Helping Hacker Culture Grow Bibliography Welcome to the Jargon File This is the Jargon File, a comprehensive compendium of hacker slang illuminating many aspects of hackish tradition, folklore, and humor. This document (the Jargon File) is in the public domain, to be freely used, shared, and modified. There are (by intention) no legal restraints on what you can do with it, but there are traditions about its proper use to which many hackers are quite strongly attached. Please extend the courtesy of proper citation when you quote the File, ideally with a version number, as it will change and grow over time. (Examples of appropriate citation form: "Jargon File 4.4.4" or "The on-line hacker Jargon File, version 4.4.4, 14 Aug 2003".) The Jargon File is a common heritage of the hacker culture. Over the years a number of individuals have volunteered considerable time to maintaining the File and been recognized by the net at large as editors of it. Editorial responsibilities include: to collate contributions and suggestions from others; to seek out corroborating information; to cross-reference related entries; to keep the file in a consistent format; and to announce and distribute updated versions periodically. Current volunteer editors include: Eric Raymond Although there is no requirement that you do so, it is considered good form to check with an editor before quoting the File in a published work or commercial product. We may have additional information that would be helpful to you and can assist you in framing your quote to reflect not only the letter of the File but its spirit as well. All contributions and suggestions about this file sent to a volunteer editor are gratefully received and will be regarded, unless otherwise labelled, as freely given donations for possible use as part of this public-domain file. From time to time a snapshot of this file has been polished, edited, and formatted for commercial publication with the cooperation of the volunteer editors and the hacker community at large. If you wish to have a bound paper copy of this file, you may find it convenient to purchase one of these. They often contain additional material not found in on-line versions. The three `authorized' editions so far are described in the Revision History section; there may be more in the future. The Jargon File's online rendition uses an unusually large number of special characters.

Format for New Entries Chapter 1. Hacker Slang and Hacker Culture This document is a collection of slang terms used by various subcultures of computer hackers. Though some technical material is included for background and flavor, it is not a technical dictionary; what we describe here is the language hackers use among themselves for fun, social communication, and technical debate. The `hacker culture' is actually a loosely networked collection of subcultures that is nevertheless conscious of some important shared experiences, shared roots, and shared values. It has its own myths, heroes, villains, folk epics, in-jokes, taboos, and dreams. Because hackers as a group are particularly creative people who define themselves partly by rejection of `normal' values and working habits, it has unusually rich and conscious traditions for an intentional culture less than 50 years old. As usual with slang, the special vocabulary of hackers helps hold places in the community and expresses shared values and experiences. Also as usual, not knowing the slang (or using it inappropriately) defines one as an outsider, a mundane, or (worst of all in hackish vocabulary) possibly even a suit. All human cultures use slang in this threefold way -- as a tool of communication, and of inclusion, and of exclusion. Among hackers, though, slang has a subtler aspect, paralleled perhaps in the slang of jazz musicians and some kinds of fine artists but hard to detect in most technical or scientific cultures; parts of it are code for shared states of consciousness. There is a whole range of altered states and problem-solving mental stances basic to high-level hacking which don't fit into conventional linguistic reality any better than a Coltrane solo or one of Maurits Escher's surreal trompe l'oeil compositions (Escher is a favorite of hackers), and hacker slang encodes these subtleties in many unobvious ways. As a simple example, take the distinction between a kluge and an elegant solution, and the differing connotations attached to each. The distinction is not only of engineering significance; it reaches right back into the nature of the generative processes in program design and asserts something important about two different kinds of relationship between the hacker and the hack. Hacker slang is unusually rich in implications of this kind, of overtones and undertones that illuminate the hackish psyche. Hackers, as a rule, love wordplay and are very conscious and inventive in their use of language. These traits seem to be common in young children, but the conformity-enforcing machine we are pleased to call an educational system bludgeons them out of most of us before adolescence. Thus, linguistic invention in most subcultures of the modern West is a halting and largely unconscious process. Hackers, by contrast, regard slang formation and use as a game to be played for conscious pleasure. Their inventions thus display an almost unique combination of the neotenous enjoyment of language-play with the discrimination of educated and powerful intelligence. Further, the electronic media which knit them together are fluid, `hot' connections, well adapted to both the dissemination of new slang and the ruthless culling of weak and superannuated specimens. The results of this process give us perhaps a uniquely intense and accelerated view of linguistic evolution in action. Hacker slang also challenges some common linguistic and anthropological assumptions. For example, in the early 1990s it became fashionable to speak of `low-context' versus `high-context' communication, and to classify cultures by the preferred context level of their languages and art forms. It is usually claimed that low-context communication (characterized by precision, clarity, and completeness of self-contained utterances) is typical in cultures which value logic, objectivity, individualism, and competition; by contrast, high-context communication (elliptical, emotive, nuance-filled, multi-modal, heavily coded) is associated with cultures which value subjectivity, consensus, cooperation, and tradition. What then are we to make of hackerdom, which is themed around extremely low-context interaction with computers and exhibits primarily "low-context" values, but cultivates an almost absurdly high-context slang style? The intensity and consciousness of hackish invention make a compilation of hacker slang a particularly effective window into the surrounding culture -- and, in fact, this one is the latest version of an evolving compilation called the `Jargon File', maintained by hackers themselves since the early 1970s. This one (like its ancestors) is primarily a lexicon, but also includes topic entries which collect background or sidelight information on hacker culture that would be awkward to try to subsume under individual slang definitions. Though the format is that of a reference volume, it is intended that the material be enjoyable to browse. Even a complete outsider should find at least a chuckle on nearly every page, and much that is amusingly thought-provoking. But it is also true that hackers use humorous wordplay to make strong, sometimes combative statements about what they feel. Some of these entries reflect the views of opposing sides in disputes that have been genuinely passionate; this is deliberate. We have not tried to moderate or pretty up these disputes; rather we have attempted to ensure that everyone's sacred cows get gored, impartially. Compromise is not particularly a hackish virtue, but the honest presentation of divergent viewpoints is. The reader with minimal computer background who finds some references incomprehensibly technical can safely ignore them. We have not felt it either necessary or desirable to eliminate all such; they, too, contribute flavor, and one of this document's major intended audiences -- fledgling hackers already partway inside the culture -- will benefit from them. A selection of longer items of hacker folklore and humor is included in Appendix A. The `outside' reader's attention is particularly directed to the Portrait of J. Random Hacker in Appendix B. The Bibliography, lists some non-technical works which have either influenced or described the hacker culture. Because hackerdom is an intentional culture (one each individual must choose by action to join), one should not be surprised that the line between description and influence can become more than a little blurred. Earlier versions of the Jargon File have played a central role in spreading hacker language and the culture that goes with it to successively larger populations, and we hope and expect that this one will do likewise. Chapter 2. Of Slang, Jargon, and Techspeak Linguists usually refer to informal language as `slang' and reserve the term `jargon' for the technical vocabularies of various occupations. However, the ancestor of this collection was called the `Jargon File', and hacker slang is traditionally `the jargon'. When talking about the jargon there is therefore no convenient way to distinguish it from what a linguist would call hackers' jargon -- the formal vocabulary they learn from textbooks, technical papers, and manuals. To make a confused situation worse, the line between hacker slang and the vocabulary of technical programming and computer science is fuzzy, and shifts over time. Further, this vocabulary is shared with a wider technical culture of programmers, many of whom are not hackers and do not speak or recognize hackish slang. Accordingly, this lexicon will try to be as precise as the facts of usage permit about the distinctions among three categories: slang informal language from mainstream English or non-technical subcultures (bikers, rock fans, surfers, etc). jargon without qualifier, denotes informal `slangy' language peculiar to or predominantly found among hackers -- the subject of this lexicon. techspeak the formal technical vocabulary of programming, computer science, electronics, and other fields connected to hacking. This terminology will be consistently used throughout the remainder of this lexicon. The jargon/techspeak distinction is the delicate one. A lot of techspeak originated as jargon, and there is a steady continuing uptake of jargon into techspeak. On the other hand, a lot of jargon arises from overgeneralization of techspeak terms (there is more about this in the Jargon Construction section below). In general, we have considered techspeak any term that communicate primarily by a denotation well established in textbooks, technical dictionaries, or standards documents. A few obviously techspeak terms (names of operating systems, languages, or documents) are listed when they are tied to hacker folklore that isn't covered in formal sources, or sometimes to convey critical historical background necessary to understand other entries to which they are cross-referenced. Some other techspeak senses of jargon words are listed in order to make the jargon senses clear; where the text does not specify that a straight technical sense is under discussion, these are marked with `[techspeak]' as an etymology. Some entries have a primary sense marked this way, with subsequent jargon meanings explained in terms of it. We have also tried to indicate (where known) the apparent origins of terms. The results are probably the least reliable information in the lexicon, for several reasons. For one thing, it is well known that many hackish usages have been independently reinvented multiple times, even among the more obscure and intricate neologisms. It often seems that the generative processes underlying hackish jargon formation have an internal logic so powerful as to create substantial parallelism across separate cultures and even in different languages! For another, the networks tend to propagate innovations so quickly that `first use' is often impossible to pin down. And, finally, compendia like this one alter what they observe by implicitly stamping cultural approval on terms and widening their use. Despite these problems, the organized collection of jargon-related oral history for the new compilations has enabled us to put to rest quite a number of folk etymologies, place credit where credit is due, and illuminate the early history of many important hackerisms such as kluge, cruft, and foo. We believe specialist lexicographers will find many of the historical notes more than casually instructive. Chapter 3. Revision History The original Jargon File was a collection of hacker jargon from technical cultures including the MIT AI Lab, the Stanford AI lab (SAIL), and others of the old ARPANET AI/LISP/PDP-10 communities including Bolt, Beranek and Newman (BBN), Carnegie-Mellon University (CMU), and Worcester Polytechnic Institute (WPI). The Jargon File (hereafter referred to as `jargon-1' or `the File') was begun by Raphael Finkel at Stanford in 1975. From this time until the plug was finally pulled on the SAIL computer in 1991, the File was named AIWORD.RF[UP,DOC] there. Some terms in it date back considerably earlier (frob and some senses of moby, for instance, go back to the Tech Model Railroad Club at MIT and are believed to date at least back to the early 1960s). The revisions of jargon-1 were all unnumbered and may be collectively considered `Version 1'. In 1976, Mark Crispin, having seen an announcement about the File on the SAIL computer, FTPed a copy of the File to MIT. He noticed that it was hardly restricted to `AI words' and so stored the file on his directory as AI:MRC;SAIL JARGON. The file was quickly renamed JARGON > (the `>' caused versioning under ITS) as a flurry of enhancements were made by Mark Crispin and Guy L. Steele Jr. Unfortunately, amidst all this activity, nobody thought of correcting the term `jargon' to `slang' until the compendium had already become widely known as the Jargon File. Raphael Finkel dropped out of active participation shortly thereafter and Don Woods became the SAIL contact for the File (which was subsequently kept in duplicate at SAIL and MIT, with periodic resynchronizations). The File expanded by fits and starts until about 1983; Richard Stallman was prominent among the contributors, adding many MIT and ITS-related coinages. In Spring 1981, a hacker named Charles Spurgeon got a large chunk of the File published in Stewart Brand's CoEvolution Quarterly (issue 29, pages 26--35) with illustrations by Phil Wadler and Guy Steele (including a couple of the Crunchly cartoons). This appears to have been the File's first paper publication. A late version of jargon-1, expanded with commentary for the mass market, was edited by Guy Steele into a book published in 1983 as The Hacker's Dictionary (Harper & Row CN 1082, ISBN 0-06-091082-8). The other jargon-1 editors (Raphael Finkel, Don Woods, and Mark Crispin) contributed to this revision, as did Richard M. Stallman and Geoff Goodfellow. This book (now out of print) is hereafter referred to as `Steele-1983' and those six as the Steele-1983 coauthors. Shortly after the publication of Steele-1983, the File effectively stopped growing and changing. Originally, this was due to a desire to freeze the file temporarily to facilitate the production of Steele-1983, but external conditions caused the `temporary' freeze to become permanent. The AI Lab culture had been hit hard in the late 1970s by funding cuts and the resulting administrative decision to use vendor-supported hardware and software instead of homebrew whenever possible. At MIT, most AI work had turned to dedicated LISP Machines. At the same time, the commercialization of AI technology lured some of the AI Lab's best and brightest away to startups along the Route 128 strip in Massachusetts and out West in Silicon Valley. The startups built LISP machines for MIT; the central MIT-AI computer became a TWENEX system rather than a host for the AI hackers' beloved ITS. The Stanford AI Lab had effectively ceased to exist by 1980, although the SAIL computer continued as a Computer Science Department resource until 1991. Stanford became a major TWENEX site, at one point operating more than a dozen TOPS-20 systems; but by the mid-1980s most of the interesting software work was being done on the emerging BSD Unix standard. In April 1983, the PDP-10-centered cultures that had nourished the File were dealt a death-blow by the cancellation of the Jupiter project at Digital Equipment Corporation. The File's compilers, already dispersed, moved on to other things. Steele-1983 was partly a monument to what its authors thought was a dying tradition; no one involved realized at the time just how wide its influence was to be. By the mid-1980s the File's content was dated, but the legend that had grown up around it never quite died out. The book, and softcopies obtained off the ARPANET, circulated even in cultures far removed from MIT and Stanford; the content exerted a strong and continuing influence on hacker language and humor. Even as the advent of the microcomputer and other trends fueled a tremendous expansion of hackerdom, the File (and related materials such as the Some AI Koans in Appendix A) came to be seen as a sort of sacred epic, a hacker-culture Matter of Britain chronicling the heroic exploits of the Knights of the Lab. The pace of change in hackerdom at large accelerated tremendously -- but the Jargon File, having passed from living document to icon, remained essentially untouched for seven years. This revision contains nearly the entire text of a late version of jargon-1 (a few obsolete PDP-10-related entries were dropped after careful consultation with the editors of Steele-1983). It merges in about 80% of the Steele-1983 text, omitting some framing material and a very few entries introduced in Steele-1983 that are now also obsolete. This new version casts a wider net than the old Jargon File; its aim is to cover not just AI or PDP-10 hacker culture but all the technical computing cultures wherein the true hacker-nature is manifested. More than half of the entries now derive from Usenet and represent jargon now current in the C and Unix communities, but special efforts have been made to collect jargon from other cultures including IBM PC programmers, Amiga fans, Mac enthusiasts, and even the IBM mainframe world. Eric S. Raymond maintains the new File with assistance from Guy L. Steele Jr. ; these are the persons primarily reflected in the File's editorial `we', though we take pleasure in acknowledging the special contribution of the other coauthors of Steele-1983.

Version numbering: Version numbers should be read as major.minor.revision. Major version 1 is reserved for the `old' (ITS) Jargon File, jargon-1. Major version 2 encompasses revisions by ESR (Eric S. Raymond) with assistance from GLS (Guy L. Steele, Jr.) leading up to and including the second paper edition. From now on, major version number N.00 will probably correspond to the Nth paper edition. Usually later versions will either completely supersede or incorporate earlier versions, so there is generally no point in keeping old versions around. Our thanks to the coauthors of Steele-1983 for oversight and assistance, and to the hundreds of Usenetters (too many to name here) who contributed entries and encouragement. More thanks go to several of the old-timers on the Usenet group alt.folklore.computers, who contributed much useful commentary and many corrections and valuable historical perspective: Joseph M. Newcomer , Bernie Cosell , Earl Boebert , and Joe Morris . We were fortunate enough to have the aid of some accomplished linguists. David Stampe and Charles Hoequist contributed valuable criticism; Joe Keane helped us improve the pronunciation guides. A few bits of this text quote previous works. We are indebted to Brian A. LaMacchia for obtaining permission for us to use material from the TMRC Dictionary; also, Don Libes contributed some appropriate material from his excellent book Life With UNIX. We thank Per Lindberg , author of the remarkable Swedish-language 'zine Hackerbladet, for bringing FOO! comics to our attention and smuggling one of the IBM hacker underground's own baby jargon files out to us. Thanks also to Maarten Litmaath for generously allowing the inclusion of the ASCII pronunciation guide he formerly maintained. And our gratitude to Marc Weiser of XEROX PARC for securing us permission to quote from PARC's own jargon lexicon and shipping us a copy. It is a particular pleasure to acknowledge the major contributions of Mark Brader and Steve Summit to the File and Dictionary; they have read and reread many drafts, checked facts, caught typos, submitted an amazing number of thoughtful comments, and done yeoman service in catching typos and minor usage bobbles. Their rare combination of enthusiasm, persistence, wide-ranging technical knowledge, and precisionism in matters of language has been of invaluable help. Indeed, the sustained volume and quality of Mr. Brader's input over a decade and several different editions has only allowed him to escape co-editor credit by the slimmest of margins. Finally, George V. Reilly helped with TeX arcana and painstakingly proofread some 2.7 and 2.8 versions, and Eric Tiedemann contributed sage advice throughout on rhetoric, amphigory, and philosophunculism. Chapter 4. Jargon Construction Table of Contents Verb Doubling Soundalike Slang The -P Convention Overgeneralization Spoken inarticulations Anthropomorphization Comparatives There are some standard methods of jargonification that became established quite early (i.e., before 1970), spreading from such sources as the Tech Model Railroad Club, the PDP-1 SPACEWAR hackers, and John McCarthy's original crew of LISPers. These include verb doubling, soundalike slang, the `-P' convention, overgeneralization, spoken inarticulations, and anthropomorphization. Each is discussed below. We also cover the standard comparatives for design quality. Of these six, verb doubling, overgeneralization, anthropomorphization, and (especially) spoken inarticulations have become quite general; but soundalike slang is still largely confined to MIT and other large universities, and the `-P' convention is found only where LISPers flourish. Verb Doubling A standard construction in English is to double a verb and use it as an exclamation, such as "Bang, bang!" or "Quack, quack!". Most of these are names for noises. Hackers also double verbs as a concise, sometimes sarcastic comment on what the implied subject does. Also, a doubled verb is often used to terminate a conversation, in the process remarking on the current state of affairs or what the speaker intends to do next. Typical examples involve win, lose, hack, flame, barf, chomp: "The disk heads just crashed." "Lose, lose." "Mostly he talked about his latest crock. Flame, flame." "Boy, what a bagbiter! Chomp, chomp! Some verb-doubled constructions have special meanings not immediately obvious from the verb. These have their own listings in the lexicon. The Usenet culture has one tripling convention unrelated to this; the names of `joke' topic groups often have a tripled last element. The first and paradigmatic example was alt.swedish.chef.bork.bork.bork (a Muppet Show reference); other infamous examples have included: * alt.french.captain.borg.borg.borg * alt.wesley.crusher.die.die.die * comp.unix.internals.system.calls.brk.brk.brk * sci.physics.edward.teller.boom.boom.boom * alt.sadistic.dentists.drill.drill.drill These two traditions fuse in the newsgroup alt.adjective.noun.verb.verb.verb, devoted to humor based on deliberately confounding parts of speech. Several observers have noted that the contents of this group is excellently representative of the peculiarities of hacker humor. Soundalike Slang Hackers will often make rhymes or puns in order to convert an ordinary word or phrase into something more interesting. It is considered particularly flavorful if the phrase is bent so as to include some other jargon word; thus the computer hobbyist magazine Dr. Dobb's Journal is almost always referred to among hackers as `Dr. Frob's Journal' or simply `Dr. Frob's'. Terms of this kind that have been in fairly wide use include names for newspapers: * Boston Herald -> Horrid (or Harried) * Boston Globe -> Boston Glob * Houston (or San Francisco) Chronicle -> the Crocknicle (or the Comical) * New York Times -> New York Slime * Wall Street Journal -> Wall Street Urinal However, terms like these are often made up on the spur of the moment. Standard examples include: * Data General -> Dirty Genitals * IBM 360 -> IBM Three-Sickly * Government Property -- Do Not Duplicate (on keys) -> Government Duplicity -- Do Not Propagate * for historical reasons -> for hysterical raisins * Margaret Jacks Hall (the CS building at Stanford) -> Marginal Hacks Hall * Microsoft -> Microsloth * Internet Explorer -> Internet Exploiter * FrontPage -> AffrontPage * VB.NET -> VB Nyet * Lotus Notes -> Lotus Bloats * Microsoft Outlook -> Microsoft Outhouse * Linux -> Linsux * FreeBSD -> FreeLSD * C# -> C Flat This is not really similar to the Cockney rhyming slang it has been compared to in the past, because Cockney substitutions are opaque whereas hacker punning jargon is intentionally transparent. The -P Convention Turning a word into a question by appending the syllable `P'; from the LISP convention of appending the letter `P' to denote a predicate (a boolean-valued function). The question should expect a yes/no answer, though it needn't. (See T and NIL.) At dinnertime: Q: "Foodp?" A: "Yeah, I'm pretty hungry." or "T!" At any time: Q: "State-of-the-world-P?" A: (Straight) "I'm about to go home." A: (Humorous) "Yes, the world has a state." On the phone to Florida: Q: "State-p Florida?" A: "Been reading JARGON.TXT again, eh?" [Once, when we were at a Chinese restaurant, Bill Gosper wanted to know whether someone would like to share with him a two-person-sized bowl of soup. His inquiry was: "Split-p soup?" -- GLS] Overgeneralization A very conspicuous feature of jargon is the frequency with which techspeak items such as names of program tools, command language primitives, and even assembler opcodes are applied to contexts outside of computing wherever hackers find amusing analogies to them. Thus (to cite one of the best-known examples) Unix hackers often grep for things rather than searching for them. Many of the lexicon entries are generalizations of exactly this kind. Hackers enjoy overgeneralization on the grammatical level as well. Many hackers love to take various words and add the wrong endings to them to make nouns and verbs, often by extending a standard rule to nonuniform cases (or vice versa). For example, because porous -> porosity and generous -> generosity, hackers happily generalize: * mysterious -> mysteriosity * ferrous -> ferrosity * obvious -> obviosity * dubious -> dubiosity Another class of common construction uses the suffix `-itude' to abstract a quality from just about any adjective or noun. This usage arises especially in cases where mainstream English would perform the same abstraction through `-iness' or `-ingness'. Thus: * win -> winnitude (a common exclamation) * loss -> lossitude * cruft -> cruftitude * lame -> lameitude Some hackers cheerfully reverse this transformation; they argue, for example, that the horizontal degree lines on a globe ought to be called `lats' -- after all, they're measuring latitude! Also, note that all nouns can be verbed. E.g.: "All nouns can be verbed", "I'll mouse it up", "Hang on while I clipboard it over", "I'm grepping the files". English as a whole is already heading in this direction (towards pure-positional grammar like Chinese); hackers are simply a bit ahead of the curve. The suffix "-full" can also be applied in generalized and fanciful ways, as in "As soon as you have more than one cachefull of data, the system starts thrashing," or "As soon as I have more than one headfull of ideas, I start writing it all down." A common use is "screenfull", meaning the amount of text that will fit on one screen, usually in text mode where you have no choice as to character size. Another common form is "bufferfull". However, hackers avoid the unimaginative verb-making techniques characteristic of marketroids, bean-counters, and the Pentagon; a hacker would never, for example, `productize', `prioritize', or `securitize' things. Hackers have a strong aversion to bureaucratic bafflegab and regard those who use it with contempt. Similarly, all verbs can be nouned. This is only a slight overgeneralization in modern English; in hackish, however, it is good form to mark them in some standard nonstandard way. Thus: * win -> winnitude, winnage * disgust -> disgustitude * hack -> hackification Further, note the prevalence of certain kinds of nonstandard plural forms. Some of these go back quite a ways; the TMRC Dictionary includes an entry which implies that the plural of `mouse' is meeces, and notes that the defined plural of `caboose' is `cabeese'. This latter has apparently been standard (or at least a standard joke) among railfans (railroad enthusiasts) for many years On a similarly Anglo-Saxon note, almost anything ending in `x' may form plurals in `-xen' (see VAXen and boxen in the main text). Even words ending in phonetic /k/ alone are sometimes treated this way; e.g., `soxen' for a bunch of socks. Other funny plurals are the Hebrew-style `frobbotzim' for the plural of `frobbozz' (see frobnitz) and `Unices' and `Twenices' (rather than `Unixes' and `Twenexes'; see Unix, TWENEX in main text). But note that `Twenexen' was never used, and `Unixen' was not sighted in the wild until the year 2000, thirty years after it might logically have come into use; it has been suggested that this is because `-ix' and `-ex' are Latin singular endings that attract a Latinate plural. Among Perl hackers it is reported that `comma' and `semicolon' pluralize as `commata' and `semicola' respectively. Finally, it has been suggested to general approval that the plural of `mongoose' ought to be `polygoose'. The pattern here, as with other hackish grammatical quirks, is generalization of an inflectional rule that in English is either an import or a fossil (such as the Hebrew plural ending `-im', or the Anglo-Saxon plural suffix `-en') to cases where it isn't normally considered to apply. This is not `poor grammar', as hackers are generally quite well aware of what they are doing when they distort the language. It is grammatical creativity, a form of playfulness. It is done not to impress but to amuse, and never at the expense of clarity. Spoken inarticulations Words such as `mumble', `sigh', and `groan' are spoken in places where their referent might more naturally be used. It has been suggested that this usage derives from the impossibility of representing such noises on a comm link or in electronic mail, MUDs, and IRC channels (interestingly, the same sorts of constructions have been showing up with increasing frequency in comic strips). Another expression sometimes heard is "Complain!", meaning "I have a complaint!" Anthropomorphization Semantically, one rich source of jargon constructions is the hackish tendency to anthropomorphize hardware and software. English purists and academic computer scientists frequently look down on others for anthropomorphizing hardware and software, considering this sort of behavior to be characteristic of naive misunderstanding. But most hackers anthropomorphize freely, frequently describing program behavior in terms of wants and desires. Thus it is common to hear hardware or software talked about as though it has homunculi talking to each other inside it, with intentions and desires. Thus, one hears "The protocol handler got confused", or that programs "are trying" to do things, or one may say of a routine that "its goal in life is to X". Or: "You can't run those two cards on the same bus; they fight over interrupt 9." One even hears explanations like "... and its poor little brain couldn't understand X, and it died." Sometimes modelling things this way actually seems to make them easier to understand, perhaps because it's instinctively natural to think of anything with a really complex behavioral repertoire as `like a person' rather than `like a thing'. At first glance, to anyone who understands how these programs actually work, this seems like an absurdity. As hackers are among the people who know best how these phenomena work, it seems odd that they would use language that seems to ascribe consciousness to them. The mind-set behind this tendency thus demands examination. The key to understanding this kind of usage is that it isn't done in a naive way; hackers don't personalize their stuff in the sense of feeling empathy with it, nor do they mystically believe that the things they work on every day are `alive'. To the contrary: hackers who anthropomorphize are expressing not a vitalistic view of program behavior but a mechanistic view of human behavior. Almost all hackers subscribe to the mechanistic, materialistic ontology of science (this is in practice true even of most of the minority with contrary religious theories). In this view, people are biological machines -- consciousness is an interesting and valuable epiphenomenon, but mind is implemented in machinery which is not fundamentally different in information-processing capacity from computers. Hackers tend to take this a step further and argue that the difference between a substrate of CHON atoms and water and a substrate of silicon and metal is a relatively unimportant one; what matters, what makes a thing `alive', is information and richness of pattern. This is animism from the flip side; it implies that humans and computers and dolphins and rocks are all machines exhibiting a continuum of modes of `consciousness' according to their information-processing capacity. Because hackers accept that a human machine can have intentions, it is therefore easy for them to ascribe consciousness and intention to other complex patterned systems such as computers. If consciousness is mechanical, it is neither more or less absurd to say that "The program wants to go into an infinite loop" than it is to say that "I want to go eat some chocolate" -- and even defensible to say that "The stone, once dropped, wants to move towards the center of the earth". This viewpoint has respectable company in academic philosophy. Daniel Dennett organizes explanations of behavior using three stances: the "physical stance" (thing-to-be-explained as a physical object), the "design stance" (thing-to-be-explained as an artifact), and the "intentional stance" (thing-to-be-explained as an agent with desires and intentions). Which stances are appropriate is a matter not of abstract truth but of utility. Hackers typically view simple programs from the design stance, but more complex ones are often modelled using the intentional stance. It has also been argued that the anthropomorphization of software and hardware reflects a blurring of the boundary between the programmer and his artifacts -- the human qualities belong to the programmer and the code merely expresses these qualities as his/her proxy. On this view, a hacker saying a piece of code `got confused' is really saying that he (or she) was confused about exactly what he wanted the computer to do, the code naturally incorporated this confusion, and the code expressed the programmer's confusion when executed by crashing or otherwise misbehaving. Note that by displacing from "I got confused" to "It got confused", the programmer is not avoiding responsibility, but rather getting some analytical distance in order to be able to consider the bug dispassionately. It has also been suggested that anthropomorphizing complex systems is actually an expression of humility, a way of acknowleging that simple rules we do understand (or that we invented) can lead to emergent behavioral complexities that we don't completely understand. All three explanations accurately model hacker psychology, and should be considered complementary rather than competing. Comparatives Finally, note that many words in hacker jargon have to be understood as members of sets of comparatives. This is especially true of the adjectives and nouns used to describe the beauty and functional quality of code. Here is an approximately correct spectrum: monstrosity brain-damage screw bug lose misfeature crock kluge hack win feature elegance perfection The last is spoken of as a mythical absolute, approximated but never actually attained. Another similar scale is used for describing the reliability of software: broken flaky dodgy fragile brittle solid robust bulletproof armor-plated Note, however, that `dodgy' is primarily Commonwealth Hackish (it is rare in the U.S.) and may change places with `flaky' for some speakers. Coinages for describing lossage seem to call forth the very finest in hackish linguistic inventiveness; it has been truly said that hackers have even more words for equipment failures than Yiddish has for obnoxious people. Chapter 5. Hacker Writing Style We've already seen that hackers often coin jargon by overgeneralizing grammatical rules. This is one aspect of a more general fondness for form-versus-content language jokes that shows up particularly in hackish writing. One correspondent reports that he consistently misspells `wrong' as `worng'. Others have been known to criticize glitches in Jargon File drafts by observing (in the mode of Douglas Hofstadter) "This sentence no verb", or "Too repetetetive", or "Bad speling", or "Incorrectspa cing." Similarly, intentional spoonerisms are often made of phrases relating to confusion or things that are confusing; `dain bramage' for `brain damage' is perhaps the most common (similarly, a hacker would be likely to write "Excuse me, I'm cixelsyd today", rather than "I'm dyslexic today"). This sort of thing is quite common and is enjoyed by all concerned. Hackers tend to use quotes as balanced delimiters like parentheses, much to the dismay of American editors. Thus, if "Jim is going" is a phrase, and so are "Bill runs" and "Spock groks", then hackers generally prefer to write: "Jim is going", "Bill runs", and "Spock groks". This is incorrect according to standard American usage (which would put the continuation commas and the final period inside the string quotes); however, it is counter-intuitive to hackers to mutilate literal strings with characters that don't belong in them. Given the sorts of examples that can come up in discussions of programming, American-style quoting can even be grossly misleading. When communicating command lines or small pieces of code, extra characters can be a real pain in the neck. Consider, for example, a sentence in a vi tutorial that looks like this: Then delete a line from the file by typing "dd". Standard usage would make this Then delete a line from the file by typing "dd." but that would be very bad -- because the reader would be prone to type the string d-d-dot, and it happens that in vi(1), dot repeats the last command accepted. The net result would be to delete two lines! The Jargon File follows hackish usage throughout. Interestingly, a similar style is now preferred practice in Great Britain, though the older style (which became established for typographical reasons having to do with the aesthetics of comma and quotes in typeset text) is still accepted there. Hart's Rules and the Oxford Dictionary for Writers and Editors call the hacker-like style `new' or `logical' quoting. This returns British English to the style many other languages (including Spanish, French, Italian, Catalan, and German) have been using all along. Another hacker habit is a tendency to distinguish between `scare' quotes and `speech' quotes; that is, to use British-style single quotes for marking and reserve American-style double quotes for actual reports of speech or text included from elsewhere. Interestingly, some authorities describe this as correct general usage, but mainstream American English has gone to using double-quotes indiscriminately enough that hacker usage appears marked [and, in fact, I thought this was a personal quirk of mine until I checked with Usenet --ESR] One further permutation that is definitely not standard is a hackish tendency to do marking quotes by using apostrophes (single quotes) in pairs; that is, 'like this'. This is modelled on string and character literal syntax in some programming languages (reinforced by the fact that many character-only terminals display the apostrophe in typewriter style, as a vertical single quote). One quirk that shows up frequently in the email style of Unix hackers in particular is a tendency for some things that are normally all-lowercase (including usernames and the names of commands and C routines) to remain uncapitalized even when they occur at the beginning of sentences. It is clear that, for many hackers, the case of such identifiers becomes a part of their internal representation (the `spelling') and cannot be overridden without mental effort (an appropriate reflex because Unix and C both distinguish cases and confusing them can lead to lossage). A way of escaping this dilemma is simply to avoid using these constructions at the beginning of sentences. There seems to be a meta-rule behind these nonstandard hackerisms to the effect that precision of expression is more important than conformance to traditional rules; where the latter create ambiguity or lose information they can be discarded without a second thought. It is notable in this respect that other hackish inventions (for example, in vocabulary) also tend to carry very precise shades of meaning even when constructed to appear slangy and loose. In fact, to a hacker, the contrast between `loose' form and `tight' content in jargon is a substantial part of its humor! Hackers have also developed a number of punctuation and emphasis conventions adapted to single-font all-ASCII communications links, and these are occasionally carried over into written documents even when normal means of font changes, underlining, and the like are available. One of these is that TEXT IN ALL CAPS IS INTERPRETED AS `LOUD', and this becomes such an ingrained synesthetic reflex that a person who goes to caps-lock while in talk mode may be asked to "stop shouting, please, you're hurting my ears!". Also, it is common to use bracketing with unusual characters to signify emphasis. The asterisk is most common, as in "What the *hell*?" even though this interferes with the common use of the asterisk suffix as a footnote mark. The underscore is also common, suggesting underlining (this is particularly common with book titles; for example, "It is often alleged that Joe Haldeman wrote _The_Forever_War_ as a rebuttal to Robert Heinlein's earlier novel of the future military, _Starship_Troopers_."). Other forms exemplified by "=hell=", "\hell/", or "/hell/" are occasionally seen (it's claimed that in the last example the first slash pushes the letters over to the right to make them italic, and the second keeps them from falling over). On FidoNet, you might see #bright# and ^dark^ text, which was actually interpreted by some reader software. Finally, words may also be emphasized L I K E T H I S, or by a series of carets (^) under them on the next line of the text. There is a semantic difference between *emphasis like this* (which emphasizes the phrase as a whole), and *emphasis* *like* *this* (which suggests the writer speaking very slowly and distinctly, as if to a very young child or a mentally impaired person). Bracketing a word with the `*' character may also indicate that the writer wishes readers to consider that an action is taking place or that a sound is being made. Examples: *bang*, *hic*, *ring*, *grin*, *kick*, *stomp*, *mumble*. One might also see the above sound effects as , , , , , , . This use of angle brackets to mark their contents originally derives from conventions used in BNF, but since about 1993 it has been reinforced by the HTML markup used on the World Wide Web. Angle-bracket enclosure is also used to indicate that a term stands for some random member of a larger class (this is straight from BNF). Examples like the following are common: So this walks into a bar one day... There is also an accepted convention for `writing under erasure'; the text> Be nice to this fool^H^H^H^Hgentleman, he's visiting from corporate HQ. reads roughly as "Be nice to this fool, er, gentleman...", with irony emphasized. The digraph ^H is often used as a print representation for a backspace, and was actually very visible on old-style printing terminals. As the text was being composed the characters would be echoed and printed immediately, and when a correction was made the backspace keystrokes would be echoed with the string `^H'. Of course, the final composed text would have no trace of the backspace characters (or the original erroneous text). Accidental writing under erasure occurs when using the Unix talk program to chat interactively to another user. On a PC-style keyboard most users instinctively press the backspace key to delete mistakes, but this may not achieve the desired effect, and merely displays a ^H symbol. The user typically presses backspace a few times before their brain realises the problem -- especially likely if the user is a touch-typist -- and since each character is transmitted as soon as it is typed, Freudian slips and other inadvertent admissions are (barring network delays) clearly visible for the other user to see. Deliberate use of ^H for writing under erasure parallels (and may have been influenced by) the ironic use of `slashouts' in science-fiction fanzines. A related habit uses editor commands to signify corrections to previous text. This custom faded in email as more mailers got good editing capabilities, only to take on new life on IRCs and other line-based chat systems. charlie: I've seen that term used on alt.foobar often. lisa: Send it to Erik for the File. lisa: Oops...s/Erik/Eric/. The s/Erik/Eric/ says "change Erik to Eric in the preceding". This syntax is borrowed from the Unix editing tools ed and sed, but is widely recognized by non-Unix hackers as well. In a formula, * signifies multiplication but two asterisks in a row are a shorthand for exponentiation (this derives from FORTRAN, and is also used in Ada). Thus, one might write 2 ** 8 = 256. Another notation for exponentiation one sees more frequently uses the caret (^, ASCII 1011110); one might write instead 2^8 = 256. This goes all the way back to Algol-60, which used the archaic ASCII `up-arrow' that later became the caret; this was picked up by Kemeny and Kurtz's original BASIC, which in turn influenced the design of the bc(1) and dc(1) Unix tools, which have probably done most to reinforce the convention on Usenet. (TeX math mode also uses ^ for exponention.) The notation is mildly confusing to C programmers, because ^ means bitwise exclusive-or in C. Despite this, it was favored 3:1 over ** in a late-1990 snapshot of Usenet. It is used consistently in this lexicon. In on-line exchanges, hackers tend to use decimal forms or improper fractions (`3.5' or `7/2') rather than `typewriter style' mixed fractions (`3-1/2'). The major motive here is probably that the former are more readable in a monospaced font, together with a desire to avoid the risk that the latter might be read as `three minus one-half'. The decimal form is definitely preferred for fractions with a terminating decimal representation; there may be some cultural influence here from the high status of scientific notation. Another on-line convention, used especially for very large or very small numbers, is taken from C (which derived it from FORTRAN). This is a form of `scientific notation' using `e' to replace `*10^'; for example, one year is about 3e7 (that is, 3 × 10 7) seconds long. The tilde (~) is commonly used in a quantifying sense of `approximately'; that is, ~50 means `about fifty'. On Usenet and in the MUD world, common C boolean, logical, and relational operators such as |, &, ||, &&, !, ==, !=, >, <, >=, and <= are often combined with English. The Pascal not-equals, <>, is also recognized, and occasionally one sees /= for not-equals (from Ada, Common Lisp, and Fortran 90). The use of prefix `!' as a loose synonym for `not-' or `no-' is particularly common; thus, `!clue' is read `no-clue' or `clueless'. A related practice borrows syntax from preferred programming languages to express ideas in a natural-language text. For example, one might see the following: In J. R. Hacker wrote: -- == Frank Foonly (Fubarco Systems) In the above, the #ifdef/#endif pair is a conditional compilation syntax from C; here, it implies that the text between (which is a flame) should be evaluated only if you have turned on (or defined on) the switch FLAME. The #include at the end is C for "include standard disclaimer here"; the `standard disclaimer' is understood to read, roughly, "These are my personal opinions and not to be construed as the official position of my employer." The top section in the example, with < at the left margin, is an example of an inclusion convention we'll discuss below. More recently, following on the huge popularity of the World Wide Web, pseudo-HTML markup has become popular for similar purposes: Your mother was a hamster and your father smelt of elderberries! You'll even see this with an HTML-style attribute modifier: You seem well-suited for a career in government. Another recent (late 1990s) construction now common on Usenet seems to be borrowed from Unix shell syntax or Perl. It consists of using a dollar sign before an uppercased form of a word or acronym to suggest any random member of the class indicated by the word. Thus: `$PHB' means "any random member of the class `Pointy-Haired Boss'". Hackers also mix letters and numbers more freely than in mainstream usage. In particular, it is good hackish style to write a digit sequence where you intend the reader to understand the text string that names that number in English. So, hackers prefer to write `1970s' rather than `nineteen-seventies' or `1970's' (the latter looks like a possessive). It should also be noted that hackers exhibit much less reluctance to use multiply-nested parentheses than is normal in English. Part of this is almost certainly due to influence from LISP (which uses deeply nested parentheses (like this (see?)) in its syntax a lot), but it has also been suggested that a more basic hacker trait of enjoying playing with complexity and pushing systems to their limits is in operation. Finally, it is worth mentioning that many studies of on-line communication have shown that electronic links have a de-inhibiting effect on people. Deprived of the body-language cues through which emotional state is expressed, people tend to forget everything about other parties except what is presented over that ASCII link. This has both good and bad effects. A good one is that it encourages honesty and tends to break down hierarchical authority relationships; a bad one is that it may encourage depersonalization and gratuitous rudeness. Perhaps in response to this, experienced netters often display a sort of conscious formal politesse in their writing that has passed out of fashion in other spoken and written media (for example, the phrase "Well said, sir!" is not uncommon). Many introverted hackers who are next to inarticulate in person communicate with considerable fluency over the net, perhaps precisely because they can forget on an unconscious level that they are dealing with people and thus don't feel stressed and anxious as they would face to face. Though it is considered gauche to publicly criticize posters for poor spelling or grammar, the network places a premium on literacy and clarity of expression. It may well be that future historians of literature will see in it a revival of the great tradition of personal letters as art. Chapter 6. Email Quotes and Inclusion Conventions One area where conventions for on-line writing are still in some flux is the marking of included material from earlier messages -- what would be called `block quotations' in ordinary English. From the usual typographic convention employed for these (smaller font at an extra indent), there derived a practice of included text being indented by one ASCII TAB (0001001) character, which under Unix and many other environments gives the appearance of an 8-space indent. Early mail and netnews readers had no facility for including messages this way, so people had to paste in copy manually. BSD Mail(1) was the first message agent to support inclusion, and early Usenetters emulated its style. But the TAB character tended to push included text too far to the right (especially in multiply nested inclusions), leading to ugly wraparounds. After a brief period of confusion (during which an inclusion leader consisting of three or four spaces became established in EMACS and a few mailers), the use of leading > or > became standard, perhaps owing to its use in ed(1) to display tabs (alternatively, it may derive from the > that some early Unix mailers used to quote lines starting with "From" in text, so they wouldn't look like the beginnings of new message headers). Inclusions within inclusions keep their > leaders, so the `nesting level' of a quotation is visually apparent. The practice of including text from the parent article when posting a followup helped solve what had been a major nuisance on Usenet: the fact that articles do not arrive at different sites in the same order. Careless posters used to post articles that would begin with, or even consist entirely of, "No, that's wrong" or "I agree" or the like. It was hard to see who was responding to what. Consequently, around 1984, new news-posting software evolved a facility to automatically include the text of a previous article, marked with "> " or whatever the poster chose. The poster was expected to delete all but the relevant lines. The result has been that, now, careless posters post articles containing the entire text of a preceding article, followed only by "No, that's wrong" or "I agree". Many people feel that this cure is worse than the original disease, and there soon appeared newsreader software designed to let the reader skip over included text if desired. Today, some posting software rejects articles containing too high a proportion of lines beginning with `>' -- but this too has led to undesirable workarounds, such as the deliberate inclusion of zero-content filler lines which aren't quoted and thus pull the message below the rejection threshold. Inclusion practice is still evolving, and disputes over the `correct' inclusion style occasionally lead to holy wars. Most netters view an inclusion as a promise that comment on it will immediately follow. The preferred, conversational style looks like this, > relevant excerpt 1 response to excerpt > relevant excerpt 2 response to excerpt > relevant excerpt 3 response to excerpt or for short messages like this: > entire message response to message Thanks to poor design of some PC-based mail agents (notably Microsoft Outlook and Outlook Express), one will occasionally see the entire quoted message after the response, like this response to message > entire message but this practice is strongly deprecated. Though > remains the standard inclusion leader, | is occasionally used for extended quotations where original variations in indentation are being retained (one mailer even combines these and uses |>). One also sees different styles of quoting a number of authors in the same message: one (deprecated because it loses information) uses a leader of > for everyone, another (the most common) is > > > > , > > > , etc. (or >>>> , >>>, etc., depending on line length and nesting depth) reflecting the original order of messages, and yet another is to use a different citation leader for each author, say > , : , | , @ (preserving nesting so that the inclusion order of messages is still apparent, or tagging the inclusions with authors' names). Yet another style is to use each poster's initials (or login name) as a citation leader for that poster. Occasionally one sees a # leader used for quotations from authoritative sources such as standards documents; the intended allusion is to the root prompt (the special Unix command prompt issued when one is running as the privileged super-user). Chapter 7. Hacker Speech Style Hackish speech generally features extremely precise diction, careful word choice, a relatively large working vocabulary, and relatively little use of contractions or street slang. Dry humor, irony, puns, and a mildly flippant attitude are highly valued -- but an underlying seriousness and intelligence are essential. One should use just enough jargon to communicate precisely and identify oneself as a member of the culture; overuse of jargon or a breathless, excessively gung-ho attitude is considered tacky and the mark of a loser. This speech style is a variety of the precisionist English normally spoken by scientists, design engineers, and academics in technical fields. In contrast with the methods of jargon construction, it is fairly constant throughout hackerdom. It has been observed that many hackers are confused by negative questions -- or, at least, that the people to whom they are talking are often confused by the sense of their answers. The problem is that they have done so much programming that distinguishes between if (going) ... and if (!going) ... that when they parse the question "Aren't you going?" it may seem to be asking the opposite question from "Are you going?", and so to merit an answer in the opposite sense. This confuses English-speaking non-hackers because they were taught to answer as though the negative part weren't there. In some other languages (including Russian, Chinese, and Japanese) the hackish interpretation is standard and the problem wouldn't arise. Hackers often find themselves wishing for a word like French `si', German `doch', or Dutch `jawel' -- a word with which one could unambiguously answer `yes' to a negative question. (See also mu) For similar reasons, English-speaking hackers almost never use double negatives, even if they live in a region where colloquial usage allows them. The thought of uttering something that logically ought to be an affirmative knowing it will be misparsed as a negative tends to disturb them. In a related vein, hackers sometimes make a game of answering questions containing logical connectives with a strictly literal rather than colloquial interpretation. A non-hacker who is indelicate enough to ask a question like "So, are you working on finding that bug now or leaving it until later?" is likely to get the perfectly correct answer "Yes!" (that is, "Yes, I'm doing it either now or later, and you didn't ask which!"). Chapter 8. International Style Although the Jargon File remains primarily a lexicon of hacker usage in American English, we have made some effort to get input from abroad. Though the hacker-speak of other languages often uses translations of jargon from English (often as transmitted to them by earlier Jargon File versions!), the local variations are interesting, and knowledge of them may be of some use to travelling hackers. There are some references herein to `Commonwealth hackish'. These are intended to describe some variations in hacker usage as reported in the English spoken in Great Britain and the Commonwealth (Canada, Australia, India, etc. -- though Canada is heavily influenced by American usage). There is also an entry on Commonwealth Hackish reporting some general phonetic and vocabulary differences from U.S. hackish. Hackers in Western Europe and (especially) Scandinavia report that they often use a mixture of English and their native languages for technical conversation. Occasionally they develop idioms in their English usage that are influenced by their native-language styles. Some of these are reported here. On the other hand, English often gives rise to grammatical and vocabulary mutations in the native language. For example, Italian hackers often use the nonexistent verbs `scrollare' (to scroll) and `deletare' (to delete) rather than native Italian scorrere and cancellare. Similarly, the English verb `to hack' has been seen conjugated in Swedish. In German, many Unix terms in English are casually declined as if they were German verbs -- thus: mount/mounten/gemountet; grep/grepen/gegrept; fork/forken/geforkt; core dump/core-dumpen, gecoredumpt. And Spanish-speaking hackers use `linkear' (to link), `debugear' (to debug), and `lockear' (to lock). European hackers report that this happens partly because the English terms make finer distinctions than are available in their native vocabularies, and partly because deliberate language-crossing makes for amusing wordplay. A few notes on hackish usages in Russian have been added where they are parallel with English idioms and thus comprehensible to English-speakers. Chapter 9. Crackers, Phreaks, and Lamers From the early 1980s onward, a flourishing culture of local, MS-DOS-based bulletin boards developed separately from Internet hackerdom. The BBS culture has, as its seamy underside, a stratum of `pirate boards' inhabited by crackers, phone phreaks, and warez d00dz. These people (mostly teenagers running IBM-PC clones from their bedrooms) have developed their own characteristic jargon, heavily influenced by skateboard lingo and underground-rock slang. While BBS technology essentially died out after the Great Internet Explosion, the cracker culture moved to IRC and other Internet-based network channels and maintained a semi-underground existence. Though crackers often call themselves `hackers', they aren't (they typically have neither significant programming ability, nor Internet expertise, nor experience with UNIX or other true multi-user systems). Their vocabulary has little overlap with hackerdom's, and hackers regard them with varying degrees of contempt. But ten years on the brightest crackers tend to become hackers, and sometimes to recall their origins by using cracker slang in a marked and heavily ironic way. This lexicon covers much of cracker slang (which is often called "leet-speak") so the reader will be able to understand both what leaks out of the cracker underground and the occasional ironic use by hackers. Here is a brief guide to cracker and warez d00dz usage: * Misspell frequently. The substitutions phone -> fone and freak -> phreak are obligatory. * Always substitute `z's for `s's. (i.e. "codes" -> "codez"). The substitution of `z' for `s' has evolved so that a `z' is now systematically put at the end of words to denote an illegal or cracking connection. Examples : Appz, passwordz, passez, utilz, MP3z, distroz, pornz, sitez, gamez, crackz, serialz, downloadz, FTPz, etc. * Type random emphasis characters after a post line (i.e. "Hey Dudes!#!$#$!#!$"). * Use the emphatic `k' prefix ("k-kool", "k-rad", "k-awesome") frequently. * Abbreviate compulsively ("I got lotsa warez w/ docs"). * TYPE ALL IN CAPS LOCK, SO IT LOOKS LIKE YOU'RE YELLING ALL THE TIME. The following letter substitutions are common: a -> 4 e -> 3 f -> ph i -> 1 or | l -> | or 1 m -> |\/| n -> |\| o -> 0 s -> 5 t -> 7 or + Thus, "elite" comes out "31337" and "all your base are belong to us" becomes "4ll y0ur b4s3 4r3 b3l0ng t0 us", Other less common substitutions include: b -> 8 c -> ( or k or |< or /< d -> <| g -> 6 or 9 h -> |-| k -> |< or /< p -> |2 u -> |_| v -> / or \/ w -> // or \/\/ x -> >< y -> '/ The word "cool" is spelled "kewl" and normally used ironically; when crackers really want to praise something they use the prefix "uber" (from German) which comes out "ub3r" or even "|_|83r" These traits are similar to those of B1FF, who originated as a parody of naive BBS users; also of his latter-day equivalent Jeff K.. Occasionally, this sort of distortion may be used as heavy sarcasm or ironically by a real hacker, as in: > I got X Windows running under Linux! d00d! u R an 31337 hax0r The words "hax0r" for "hacker" and "sux0r" for "sucks" are the most common references; more generally, to mark a term as cracker-speak one may add "0r" or "xor". Examples: "The nightly build is sux0r today." "Gotta go reboot those b0x0rz." "Man, I really ought to fix0r my .fetchmailrc." "Yeah, well he's a 'leet VMS operat0r now, so he's too good for u s." The only practice resembling this in native hacker usage is the substitution of a dollar sign of `s' in names of products or service felt to be excessively expensive, e.g. Compu$erve, Micro$oft. For further discussion of the pirate-board subculture, see lamer, elite, leech, poser, cracker, and especially warez d00dz, banner site, ratio site, leech mode. Chapter 10. Pronunciation Guide Pronunciation keys are provided in the jargon listings for all entries that are neither dictionary words pronounced as in standard English nor obvious compounds thereof. Slashes bracket phonetic pronunciations, which are to be interpreted using the following conventions: Syllables are hyphen-separated, except that an accent or back-accent follows each accented syllable (the back-accent marks a secondary accent in some words of four or more syllables). If no accent is given, the word is pronounced with equal accentuation on all syllables (this is common for abbreviations). Consonants are pronounced as in American English. The letter `g' is always hard (as in "got" rather than "giant"); `ch' is soft ("church" rather than "chemist"). The letter `j' is the sound that occurs twice in "judge". The letter `s' is always as in "pass", never a z sound. The digraph `kh' is the guttural of "loch" or "l'chaim". The digraph `gh' is the aspirated g+h of "bughouse" or "ragheap" (rare in English). Uppercase letters are pronounced as their English letter names; thus (for example) /H-L-L/ is equivalent to /aych el el/. /Z/ may be pronounced /zee/ or /zed/ depending on your local dialect. Vowels are represented as follows: Table 10.1. Vowels a back, that ah father, palm (see note) ar far, mark aw flaw, caught ay bake, rain e less, men ee easy, ski eir their, software i trip, hit i: life, sky o block, stock (see note) oh flow, sew oo loot, through or more, door ow out, how oy boy, coin uh but, some u put, foot y yet, young yoo few, chew [y]oo /oo/ with optional fronting as in `news' (/nooz/ or /nyooz/) The glyph /@/ is used for the `schwa' sound of unstressed or occluded vowels. The schwa vowel is omitted in syllables containing vocalic r, l, m or n; that is, `kitten' and `color' would be rendered /kit'n/ and /kuhl'r/, not /kit'@n/ and /kuhl'@r/. Note that the above table reflects mainly distinctions found in standard American English (that is, the neutral dialect spoken by TV network announcers and typical of educated speech in the Upper Midwest, Chicago, Minneapolis/St. Paul and Philadelphia). However, we separate /o/ from /ah/, which tend to merge in standard American. This may help readers accustomed to accents resembling British Received Pronunciation. The intent of this scheme is to permit as many readers as possible to map the pronunciations into their local dialect by ignoring some subset of the distinctions we make. Speakers of British RP, for example, can smash terminal /r/ and all unstressed vowels. Speakers of many varieties of southern American will automatically map /o/ to /aw/; and so forth. (Standard American makes a good reference dialect for this purpose because it has crisp consonants and more vowel distinctions than other major dialects, and tends to retain distinctions between unstressed vowels. It also happens to be what your editor speaks.) Entries with a pronunciation of `//' are written-only usages. (No, Unix weenies, this does not mean `pronounce like previous pronunciation'!) Chapter 11. Other Lexicon Conventions Entries are sorted in case-blind ASCII collation order (rather than the letter-by-letter order ignoring interword spacing common in mainstream dictionaries), except that all entries beginning with nonalphabetic characters are sorted before A, except that leading dash is ignored. The case-blindness is a feature, not a bug. Prefix ** is used as linguists do; to mark examples of incorrect usage. We follow the `logical' quoting convention described in the Writing Style section above. In addition, we reserve double quotes for actual excerpts of text or (sometimes invented) speech. Scare quotes (which mark a word being used in a nonstandard way), and philosopher's quotes (which turn an utterance into the string of letters or words that name it) are both rendered with single quotes. References such as malloc(3) and patch(1) are to Unix facilities (some of which, such as patch(1), are actually open source distributed over Usenet). The Unix manuals use foo(n) to refer to item foo in section (n) of the manual, where n=1 is utilities, n=2 is system calls, n=3 is C library routines, n=6 is games, and n=8 (where present) is system administration utilities. Sections 4, 5, and 7 of the manuals have changed roles frequently and in any case are not referred to in any of the entries. Various abbreviations used frequently in the lexicon are summarized here: Table 11.1. Abbreviations abbrev. abbreviation adj. adjective adv. adverb alt. alternate cav. caveat conj. conjunction esp. especially excl. exclamation imp. imperative interj. interjection n. noun obs. obsolete pl. plural poss. possibly pref. prefix prob. probably prov. proverbial quant. quantifier suff. suffix syn. synonym (or synonymous with) v. verb (may be transitive or intransitive) var. variant vi. intransitive verb vt. transitive verb Where alternate spellings or pronunciations are given, alt. separates two possibilities with nearly equal distribution, while var. prefixes one that is markedly less common than the primary. Where a term can be attributed to a particular subculture or is known to have originated there, we have tried to so indicate. Here is a list of abbreviations used in etymologies: Table 11.2. Origins Amateur Packet Radio A technical culture of ham-radio sites using AX.25 and TCP/IP for wide-area networking and BBS systems. Berkeley University of California at Berkeley BBN Bolt, Beranek & Newman Cambridge the university in England (not the city in Massachusetts where MIT happens to be located!) CMU Carnegie-Mellon University Commodore Commodore Business Machines DEC The Digital Equipment Corporation (now HP). Fairchild The Fairchild Instruments Palo Alto development group FidoNet See the FidoNet entry IBM International Business Machines MIT Massachusetts Institute of Technology; esp. the legendary MIT AI Lab culture of roughly 1971 to 1983 and its feeder groups, including the Tech Model Railroad Club NRL Naval Research Laboratories NYU New York University OED The Oxford English Dictionary Purdue Purdue University SAIL Stanford Artificial Intelligence Laboratory (at Stanford University) SI From Système International, the name for the standard abbreviations of metric nomenclature used in the sciences Stanford Stanford University Sun Sun Microsystems TMRC Some MITisms go back as far as the Tech Model Railroad Club (TMRC) at MIT c. 1960. Material marked TMRC is from An Abridged Dictionary of the TMRC Language, originally compiled by Pete Samson in 1959 UCLA University of California at Los Angeles UK the United Kingdom (England, Wales, Scotland, Northern Ireland) Usenet See the Usenet entry WPI Worcester Polytechnic Institute, site of a very active community of PDP-10 hackers during the 1970s WWW The World-Wide-Web. XEROX PARC XEROX's Palo Alto Research Center, site of much pioneering research in user interface design and networking Yale Yale University Other etymology abbreviations such as Unix and PDP-10 refer to technical cultures surrounding specific operating systems, processors, or other environments. The fact that a term is labelled with any one of these abbreviations does not necessarily mean its use is confined to that culture. In particular, many terms labelled `MIT' and `Stanford' are in quite general use. We have tried to give some indication of the distribution of speakers in the usage notes; however, a number of factors mentioned in the introduction conspire to make these indications less definite than might be desirable. A few new definitions attached to entries are marked [proposed]. These are usually generalizations suggested by editors or Usenet respondents in the process of commenting on previous definitions of those entries. These are not represented as established jargon. Chapter 12. Format for New Entries We welcome new jargon, and corrections to or amplifications of existing entries. You can improve your submission's chances of being included by adding background information on user population and years of currency. References to actual usage via URLs and/or Google pointers are particularly welcomed. All contributions and suggestions about the Jargon File will be considered donations to be placed in the public domain as part of this File, and may be used in subsequent paper editions. Submissions may be edited for accuracy, clarity and concision. We are looking to expand the File's range of technical specialties covered. There are doubtless rich veins of jargon yet untapped in the scientific computing, graphics, and networking hacker communities; also in numerical analysis, computer architectures and VLSI design, language design, and many other related fields. Send us your jargon! We are not interested in straight technical terms explained by textbooks or technical dictionaries unless an entry illuminates `underground' meanings or aspects not covered by official histories. We are also not interested in `joke' entries -- there is a lot of humor in the file but it must flow naturally out of the explanations of what hackers do and how they think. It is OK to submit items of jargon you have originated if they have spread to the point of being used by people who are not personally acquainted with you. We prefer items to be attested by independent submission from two different sites. The Jargon File will be regularly maintained and made available for browsing on the World Wide Web, and will include a version number. Read it, pass it around, contribute -- this is your monument! The Jargon Lexicon [crunchly-1.png] The Crunchly saga begins here. (The next cartoon in the Crunchly saga is 73-05-18.) The infamous Crunchly cartoons by The Great Quux are woven into the lexicon, each next to an appropriate entry. To read them in the sequence in which they were written, chase pointers from here using the `next cartoon' information in the captions. A few don't have next pointers; these are vignettes from the 1973 Crunchland tableau spread that inaugurated the strip. Here is a framed version of the glossary.

Sometimes used ironically as a form of protest against the recent spate of software and algorithm patents and look and feel lawsuits. See also {UN*X}. :/dev/null: /dev·nuhl/, n. [from the Unix null device, used as a data sink] A notional `black hole' in any information space being discussed, used, or referred to. A controversial posting, for example, might end "Kudos to rasputin@kremlin.org, flames to /dev/null". See {bit bucket}. :/me: // [IRC; common] Under most IRC, /me is the "pose" command; if you are logged on as Foonly and type "/me laughs", others watching the channel will see "* Joe Foonly laughs". This usage has been carried over to mail and news, where the reader is expected to perform the same expansion in his or her head. :0: Numeric zero, as opposed to the letter `O' (the 15th letter of the English alphabet). In their unmodified forms they look a lot alike, and various kluges invented to make them visually distinct have compounded the confusion. If your zero is center-dotted and letter-O is not, or if letter-O looks almost rectangular but zero looks more like an American football stood on end (or the reverse), you're probably looking at a modern character display (though the dotted zero seems to have originated as an option on IBM 3270 controllers). If your zero is slashed but letter-O is not, you're probably looking at an old-style ASCII graphic set descended from the default typewheel on the venerable ASR-33 Teletype (Scandinavians, for whom Ø is a letter, curse this arrangement). (Interestingly, the slashed zero long predates computers; Florian Cajori's monumental A History of Mathematical Notations notes that it was used in the twelfth and thirteenth centuries.) If letter-O has a slash across it and the zero does not, your display is tuned for a very old convention used at IBM and a few other early mainframe makers (Scandinavians curse this arrangement even more, because it means two of their letters collide). Some Burroughs/Unisys equipment displays a zero with a reversed slash. Old CDC computers rendered letter O as an unbroken oval and 0 as an oval broken at upper right and lower left. And yet another convention common on early line printers left zero unornamented but added a tail or hook to the letter-O so that it resembled an inverted Q or cursive capital letter-O (this was endorsed by a draft ANSI standard for how to draw ASCII characters, but the final standard changed the distinguisher to a tick-mark in the upper-left corner). Are we sufficiently confused yet? :1TBS: //, n. The "One True Brace Style"; see {indent style}. :2: infix. In translation software written by hackers, infix 2 often represents the syllable to with the connotation `translate to': as in dvi2ps (DVI to PostScript), int2string (integer to string), and texi2roff (Texinfo to [nt]roff). Several versions of a joke have floated around the internet in which some idiot programmer fixes the Y2K bug by changing all the Y's in something to K's, as in Januark, Februark, etc. :404: //, n. [from the HTTP error "file not found on server"] Extended to humans to convey that the subject has no idea or no clue -- sapience not found. May be used reflexively; "Uh, I'm 404ing" means "I'm drawing a blank". :404 compliant: adj. The status of a website which has been completely removed, usually by the administrators of the hosting site as a result of net abuse by the website operators. The term is a tongue-in-cheek reference to the standard "301 compliant" Murkowski Bill disclaimer used by spammers. See also: {spam}, {spamvertize}. :@-party: /at´par`tee/, n. [from the @-sign in an Internet address] (alt.: `@-sign party' /at´si:n par`tee/) A semi-closed party thrown for hackers at a science-fiction convention (esp. the annual World Science Fiction Convention or "Worldcon"); one must have a {network address} to get in, or at least be in company with someone who does. One of the most reliable opportunities for hackers to meet face to face with people who might otherwise be represented by mere phosphor dots on their screens. Compare {boink}. The first recorded @-party was held at the Westercon (a U.S. western regional SF convention) over the July 4th weekend in 1980. It is not clear exactly when the canonical @-party venue shifted to the Worldcon but it had certainly become established by Constellation in 1983. Sadly, the @-party tradition has been in decline since about 1996, mainly because having an @-address no longer functions as an effective lodge pin. We are informed, however, that rec.skydiving members have maintained a tradition of formation jumps in the shape of an @.

Common abbreviation for `abbreviation'. :ABEND: /a´bend/, /@·bend´/, n. [ABnormal END] 1. Abnormal termination (of software); {crash}; {lossage}. Derives from an error message on the IBM 360; used jokingly by hackers but seriously mainly by {code grinder}s. Usually capitalized, but may appear as `abend'. Hackers will try to persuade you that ABEND is called abend because it is what system operators do to the machine late on Friday when they want to call it a day, and hence is from the German Abend = `Evening'. 2. [alt.callahans] Absent By Enforced Net Deprivation -- used in the subject lines of postings warning friends of an imminent loss of Internet access. (This can be because of computer downtime, loss of provider, moving or illness.) Variants of this also appear: ABVND = `Absent By Voluntary Net Deprivation' and ABSEND = `Absent By Self-Enforced Net Deprivation' have been sighted. :accumulator: n. obs. 1. Archaic term for a register. On-line use of it as a synonym for register is a fairly reliable indication that the user has been around for quite a while and/or that the architecture under discussion is quite old. The term in full is almost never used of microprocessor registers, for example, though symbolic names for arithmetic registers beginning in `A' derive from historical use of the term accumulator (and not, actually, from `arithmetic'). Confusingly, though, an `A' register name prefix may also stand for address, as for example on the Motorola 680x0 family. 2. A register being used for arithmetic or logic (as opposed to addressing or a loop index), especially one being used to accumulate a sum or count of many items. This use is in context of a particular routine or stretch of code. "The FOOBAZ routine uses A3 as an accumulator." 3. One's in-basket (esp. among old-timers who might use sense 1). "You want this reviewed? Sure, just put it in the accumulator." (See {stack}.) :ACK: /ak/, interj. 1. [common; from the ASCII mnemonic for 0000110] Acknowledge. Used to register one's presence (compare mainstream Yo!). An appropriate response to {ping} or {ENQ}. 2. [from the comic strip Bloom County] An exclamation of surprised disgust, esp. in "Ack pffft!" Semi-humorous. Generally this sense is not spelled in caps (ACK) and is distinguished by a following exclamation point. 3. Used to politely interrupt someone to tell them you understand their point (see {NAK}). Thus, for example, you might cut off an overly long explanation with "Ack. Ack. Ack. I get it now". 4. An affirmative. "Think we ought to ditch that damn NT server for a Linux box?" "ACK!" There is also a usage "ACK?" (from sense 1) meaning "Are you there?", often used in email when earlier mail has produced no reply, or during a lull in {talk mode} to see if the person has gone away (the standard humorous response is of course {NAK}, i.e., "I'm not here"). :Acme: n. [from Greek akme highest point of perfection or achievement] The canonical supplier of bizarre, elaborate, and non-functional gadgetry -- where Rube Goldberg and Heath Robinson (two cartoonists who specialized in elaborate contraptions) shop. The name has been humorously expanded as A (or American) Company Making Everything. (In fact, Acme was a real brand sold from Sears Roebuck catalogs in the early 1900s.) Describing some X as an "Acme X" either means "This is {insanely great}", or, more likely, "This looks {insanely great} on paper, but in practice it's really easy to shoot yourself in the foot with it." Compare {pistol}. This term, specially cherished by American hackers and explained here for the benefit of our overseas brethren, comes from the Warner Brothers' series of "Road-runner" cartoons. In these cartoons, the famished Wile E. Coyote was forever attempting to catch up with, trap, and eat the Road-runner. His attempts usually involved one or more high-technology Rube Goldberg devices -- rocket jetpacks, catapults, magnetic traps, high-powered slingshots, etc. These were usually delivered in large wooden crates labeled prominently with the Acme name -- which, probably not by coincidence, was the trade name of the animation rotation board used by cartoonists since forever. Acme devices invariably malfunctioned in improbable and violent ways. :ad-hockery: /ad·hok'@r·ee/, n. [Purdue] 1. Gratuitous assumptions made inside certain programs, esp. expert systems, which lead to the appearance of semi-intelligent behavior but are in fact entirely arbitrary. For example, fuzzy-matching of input tokens that might be typing errors against a symbol table can make it look as though a program knows how to spell. 2. Special-case code to cope with some awkward input that would otherwise cause a program to {choke}, presuming normal inputs are dealt with in some cleaner and more regular way. Also called ad-hackery, ad-hocity (/ad-hos'@-tee/), ad-crockery. See also {ELIZA effect}. [73-10-31.png] This is {ad-hockery} in action. (The next cartoon in the Crunchly saga is 74-08-18) :address harvester: n. A robot that searches web pages and/or filters netnews traffic looking for valid email addresses. Some address harvesters are benign, used only for compiling address directories. Most, unfortunately, are run by miscreants compiling address lists to {spam}. Address harvesters can be foiled by a {teergrube}. :adger: /aj´r/, vt. [UCLA mutant of {nadger}, poss. also from the middle name of an infamous {tenured graduate student}] To make a bonehead move with consequences that could have been foreseen with even slight mental effort. E.g., "He started removing files and promptly adgered the whole project". Compare {dumbass attack}. :admin: /ad·min´/, n. Short for `administrator'; very commonly used in speech or on-line to refer to the systems person in charge on a computer. Common constructions on this include sysadmin and site admin (emphasizing the administrator's role as a site contact for email and news) or newsadmin (focusing specifically on news). Compare {postmaster}, {sysop}, {system mangler}. :ADVENT: /ad´vent/, n. The prototypical computer adventure game, first designed by Will Crowther on the {PDP-10} in the mid-1970s as an attempt at computer-refereed fantasy gaming, and expanded into a puzzle-oriented game by Don Woods at Stanford in 1976. (Woods had been one of the authors of {INTERCAL}.) Now better known as Adventure or Colossal Cave Adventure, but the {TOPS-10} operating system permitted only six-letter filenames in uppercase. See also {vadding}, {Zork}, and {Infocom}. Figure 1. Screen shot of the original ADVENT game Orange River Chamber You are in a splendid chamber thirty feet high. The walls are frozen rivers of orange stone. An awkward canyon and a good passage exit from east and west sidesof the chamber. A cheerful little bird is sitting here singing. >drop rod Dropped. >take bird You catch the bird in the wicker cage. >take rod Taken. >w At Top of Small Pit At your feet is a small pit breathing traces of white mist. A west passage end s here except for a small crack leading on. Rough stone steps lead down the pit. >down In Hall of Mists You are at one end of a vast hall stretching forward out of sight to the west. There are openings to either side. Nearby, a wide stone staircase leads downward. The hall is filled with wisps of white mist swaying to and fro almos t as if alive. A cold wind blows up the staircase. There is a passage at the top of a dome behind you. Rough stone steps lead up the dome. This game defined the terse, dryly humorous style since expected in text adventure games, and popularized several tag lines that have become fixtures of hacker-speak: "A huge green fierce snake bars the way!" "I see no X here" (for some noun X). "You are in a maze of twisty little passages, all alike." "You are in a little maze of twisty passages, all different." The `magic words' {xyzzy} and {plugh} also derive from this game. Crowther, by the way, participated in the exploration of the Mammoth & Flint Ridge cave system; it actually has a Colossal Cave and a Bedquilt as in the game, and the Y2 that also turns up is cavers' jargon for a map reference to a secondary entrance. ADVENT sources are available for FTP at ftp://ftp.wustl.edu/doc/misc/if-archive/games/source/advent.tar.Z. You can also play it as a Java applet. There is a good page of resources at the Colossal Cave Adventure Page. :adware: n. Software which is free to download and use but includes pop-up banner ads somewhere. See also {-ware}. :AFAIK: //, n. [Usenet; common] Abbrev. for "As Far As I Know". There is a variant AFAICT "As Far As I Can Tell"; where AFAIK suggests that the writer knows his knowledge is limited, AFAICT suggests that he feels his knowledge is as complete as anybody else's buit that the best available knowledge does not support firm conclusions. :AFJ: //, n. Written-only abbreviation for "April Fool's Joke". Elaborate April Fool's hoaxes are a long-established tradition on Usenet and Internet; see {kremvax} for an example. In fact, April Fool's Day is the only seasonal holiday consistently marked by customary observances on Internet and other hacker networks. :AFK: [MUD] Abbrev. for "Away From Keyboard". Used to notify others that you will be momentarily unavailable online. eg. "Let's not go kill that frost giant yet, I need to go AFK to make a phone call". Often MUDs will have a command to politely inform others of your absence when they try to talk with you. The term is not restricted to MUDs, however, and has become common in many chat situations, from IRC to Unix talk. :AI: /A·I/, n. Abbreviation for `Artificial Intelligence', so common that the full form is almost never written or spoken among hackers. :AI-complete: /A·I k@m·pleet'/, adj. [MIT, Stanford: by analogy with NP-complete (see {NP-})] Used to describe problems or subproblems in AI, to indicate that the solution presupposes a solution to the `strong AI problem' (that is, the synthesis of a human-level intelligence). A problem that is AI-complete is, in other words, just too hard. Examples of AI-complete problems are `The Vision Problem' (building a system that can see as well as a human) and `The Natural Language Problem' (building a system that can understand and speak a natural language as well as a human). These may appear to be modular, but all attempts so far (2002) to solve them have foundered on the amount of context information and `intelligence' they seem to require. See also {gedanken}. :airplane rule: n. "Complexity increases the possibility of failure; a twin-engine airplane has twice as many engine problems as a single-engine airplane." By analogy, in both software and electronics, the rule that simplicity increases robustness. It is correspondingly argued that the right way to build reliable systems is to put all your eggs in one basket, after making sure that you've built a really good basket. See also {KISS Principle}, {elegant}. :Alderson loop: n. [Intel] A special version of an {infinite loop} where there is an exit condition available, but inaccessible in the current implementation of the code. Typically this is created while debugging user interface code. An example would be when there is a menu stating, "Select 1-3 or 9 to quit" and 9 is not allowed by the function that takes the selection from the user. This term received its name from a programmer who had coded a modal message box in MSAccess with no Ok or Cancel buttons, thereby disabling the entire program whenever the box came up. The message box had the proper code for dismissal and even was set up so that when the non-existent Ok button was pressed the proper code would be called. :aliasing bug: n. A class of subtle programming errors that can arise in code that does dynamic allocation, esp. via malloc(3) or equivalent. If several pointers address (are aliases for) a given hunk of storage, it may happen that the storage is freed or reallocated (and thus moved) through one alias and then referenced through another, which may lead to subtle (and possibly intermittent) lossage depending on the state and the allocation history of the malloc {arena}. Avoidable by use of allocation strategies that never alias allocated core, or by use of higher-level languages, such as {LISP}, which employ a garbage collector (see {GC}). Also called a {stale pointer bug}. See also {precedence lossage}, {smash the stack}, {fandango on core}, {memory leak}, {memory smash}, {overrun screw}, {spam}. Historical note: Though this term is nowadays associated with C programming, it was already in use in a very similar sense in the Algol-60 and FORTRAN communities in the 1960s. :Alice and Bob: n. The archetypal individuals used as examples in discussions of cryptographic protocols. Originally, theorists would say something like: "A communicates with someone who claims to be B, So to be sure, A tests that B knows a secret number K. So A sends to B a random number X. B then forms Y by encrypting X under key K and sends Y back to A" Because this sort of thing is quite hard to follow, theorists stopped using the unadorned letters A and B to represent the main players and started calling them Alice and Bob. So now we say "Alice communicates with someone claiming to be Bob, and to be sure, Alice tests that Bob knows a secret number K. Alice sends to Bob a random number X. Bob then forms Y by encrypting X under key K and sends Y back to Alice". A whole mythology rapidly grew up around the metasyntactic names; see http://www.conceptlabs.co.uk/alicebob.html. In Bruce Schneier's definitive introductory text Applied Cryptography (2nd ed., 1996, John Wiley & Sons, ISBN 0-471-11709-9) he introduced a table of dramatis personae headed by Alice and Bob. Others include Carol (a participant in three- and four-party protocols), Dave (a participant in four-party protocols), Eve (an eavesdropper), Mallory (a malicious active attacker), Trent (a trusted arbitrator), Walter (a warden), Peggy (a prover) and Victor (a verifier). These names for roles are either already standard or, given the wide popularity of the book, may be expected to quickly become so. :All hardware sucks, all software sucks.: prov. [from {scary devil monastery}] A general recognition of the fallibility of any computer system, ritually intoned as an attempt to quell incipient {holy wars}. It is a common response to any sort of {bigot}. When discussing {Wintel} systems, however, it is often snidely appended with, `but some suck more than others.' :all your base are belong to us: A declaration of victory or superiority. The phrase stems from a 1991 adaptation of Toaplan's "Zero Wing" shoot-'em-up arcade game for the Sega Genesis game console. A brief introduction was added to the opening screen, and it has what many consider to be the worst Japanese-to-English translation in video game history. The introduction shows the bridge of a starship in chaos as a Borg-like figure named CATS materializes and says, "How are you gentlemen!! All your base are belong to us." [sic] In 2001, this amusing mistranslation spread virally through the Internet, bringing with it a slew of JPEGs and a movie of hacked photographs, each showing a street sign, store front, package label, etc. hacked to read "All your base are belong to us" or one of the other many supremely dopey lines from the game (such as "Somebody set us up the bomb!!!" or "What happen?"). When these phrases are used properly, the overall effect is both screamingly funny and somewhat chilling, reminiscent of the B movie "They Live". The original has been generalized to "All your X are belong to us", where X is filled in to connote a sinister takeover of some sort. Thus, "When Joe signed up for his new job at Yoyodyne, he had to sign a draconian NDA. It basically said: All your code are belong to us." Has many of the connotations of "Resistance is futile; you will be assimilated" (see {Borg}). Considered silly, and most likely to be used by the type of person that finds {Jeff K.} hilarious. :alpha geek: n. [from animal ethologists' alpha male] The most technically accomplished or skillful person in some implied context. "Ask Larry, he's the alpha geek here." :alpha particles: n. See {bit rot}. :alt: /awlt/ 1. n. The alt shift key on an IBM PC or {clone} keyboard; see {bucky bits}, sense 2 (though typical PC usage does not simply set the 0200 bit). 2. n. The option key on a Macintosh; use of this term usually reveals that the speaker hacked PCs before coming to the Mac (see also {feature key}, which is sometimes incorrectly called `alt'). 3. The alt hierarchy on Usenet, the tree of newsgroups created by users without a formal vote and approval procedure. There is a myth, not entirely implausible, that alt is acronymic for "anarchists, lunatics, and terrorists"; but in fact it is simply short for "alternative". 4. n.,obs. Rare alternate name for the ASCII ESC character (ASCII 0011011). This use, derives, with the alt key itself, from archaic PDP-10 operating systems, especially {ITS}. :alt bit: /awlt bit/, adj. See {meta bit}. :Aluminum Book: n. [MIT] Common LISP: The Language, by Guy L. Steele Jr. (Digital Press, first edition 1984, second edition 1990). Note that due to a technical screwup some printings of the second edition are actually of a color the author describes succinctly as "yucky green". See also {book titles}. :ambimouseterous: /am·b@·mows´ter·us/, /am·b@·mows´trus/, adj [modeled on ambidextrous] Able to use a mouse with either hand. :Amiga: n A series of personal computer models originally sold by Commodore, based on 680x0 processors, custom support chips and an operating system that combined some of the best features of Macintosh and Unix with compatibility with neither. The Amiga was released just as the personal computing world standardized on IBM-PC clones. This prevented it from gaining serious market share, despite the fact that the first Amigas had a substantial technological lead on the IBM XTs of the time. Instead, it acquired a small but zealous population of enthusiastic hackers who dreamt of one day unseating the clones (see {Amiga Persecution Complex}). The traits of this culture are both spoofed and illuminated in The BLAZE Humor Viewer. The strength of the Amiga platform seeded a small industry of companies building software and hardware for the platform, especially in graphics and video applications (see {video toaster}). Due to spectacular mismanagement, Commodore did hardly any R&D, allowing the competition to close Amiga's technological lead. After Commodore went bankrupt in 1994 the technology passed through several hands, none of whom did much with it. However, the Amiga is still being produced in Europe under license and has a substantial number of fans, which will probably extend the platform's life considerably. :Amiga Persecution Complex: n. The disorder suffered by a particularly egregious variety of {bigot}, those who believe that the marginality of their preferred machine is the result of some kind of industry-wide conspiracy (for without a conspiracy of some kind, the eminent superiority of their beloved shining jewel of a platform would obviously win over all, market pressures be damned!) Those afflicted are prone to engaging in {flame war}s and calling for boycotts and mailbombings. Amiga Persecution Complex is by no means limited to Amiga users; NeXT, {NeWS}, {OS/2}, Macintosh, {LISP}, and {GNU} users are also common victims. {Linux} users used to display symptoms very frequently before Linux started winning; some still do. See also {newbie}, {troll}, {holy wars}, {weenie}, {Get a life!}. :amp off: vt. [Purdue] To run in {background}. From the Unix shell `&' operator. :amper: n. Common abbreviation for the name of the ampersand (`&', ASCII 0100110) character. See {ASCII} for other synonyms. :and there was much rejoicing: [from the movie Monty Python and the Holy Grail.] Acknowledgement of a notable accomplishment. Something long-awaited, widely desired, possibly unexpected but secretly wished-for, with a suggestion that something about the problem (and perhaps the steps necessary to make it go away) was deeply disturbing to hacker sensibilities. In person, the phrase is almost invariably pronounced with the same portentious intonation as the movie. The customary in-person (approving) response is a weak and halfhearted "Yaaaay...", with one index finger raised like a flag and moved in a small circle. The reason for this, like most of the Monty Python oeuvre, cannot easily be explained outside its original context. Example: "changelog entry #436: with the foo driver brain damage taken care of, finally obsoleted BROKEN_EVIL_KLUDGE. Removed from source tree. (And there was much rejoicing)." :Angband: n., /ang´band/ Like {nethack}, {moria}, and {rogue}, one of the large freely distributed Dungeons-and-Dragons-like simulation games, available for a wide range of machines and operating systems. The name is from Tolkien's Pits of Angband (compare {elder days}, {elvish}). Has been described as "Moria on steroids"; but, unlike Moria, many aspects of the game are customizable. This leads many hackers and would-be hackers into fooling with these instead of doing productive work. There are many Angband variants, of which the most notorious is probably the rather whimsical Zangband. In this game, when a key that does not correspond to a command is pressed, the game will display "Type ? for help" 50% of the time. The other 50% of the time, random error messages including "An error has occurred because an error of type 42 has occurred" and "Windows 95 uninstalled successfully" will be displayed. Zangband also allows the player to kill Santa Claus (who has some really good stuff, but also has a lot of friends), "Bull Gates", and Barney the Dinosaur (but be watchful; Barney has a nasty case of halitosis). There is an official angband home page at http://thangorodrim.angband.org/ and a zangband one at http://www.zangband.org/. See also {Random Number God}. :angle brackets: n. Either of the characters < (ASCII 0111100) and > (ASCII 0111110) (ASCII less-than or greater-than signs). Typographers in the {Real World} use angle brackets which are either taller and slimmer (the ISO lang and rang characters), or significantly smaller (single or double guillemets) than the less-than and greater-than signs. See {broket}, {ASCII}. :angry fruit salad: n. A bad visual-interface design that uses too many colors. (This term derives, of course, from the bizarre day-glo colors found in canned fruit salad.) Too often one sees similar effects from interface designers using color window systems such as {X}; there is a tendency to create displays that are flashy and attention-getting but uncomfortable for long-term use. :annoybot: /@·noy·bot/, n. [IRC] See {bot}. :annoyware: n. A type of {shareware} that frequently disrupts normal program operation to display requests for payment to the author in return for the ability to disable the request messages. (Also called nagware) The requests generally require user action to acknowledge the message before normal operation is resumed and are often tied to the most frequently used features of the software. See also {careware}, {charityware}, {crippleware}, {freeware}, {FRS}, {guiltware}, {postcardware}, and {-ware}; compare {payware}. :ANSI standard: /an´see stan´d@rd/ The ANSI standard usage of ANSI standard refers to any practice which is typical or broadly done. It's most appropriately applied to things that everyone does that are not quite regulation. For example: ANSI standard shaking of a laser printer cartridge to get extra life from it, or the ANSI standard word tripling in names of usenet alt groups. This usage derives from the American National Standards Institute. ANSI, along with the International Organization for Standards (ISO), standardized the C programming language (see {K&R}, {Classic C}), and promulgates many other important software standards. :ANSI standard pizza: /an´see stan´d@rd peet´z@/ [CMU] Pepperoni and mushroom pizza. Coined allegedly because most pizzas ordered by CMU hackers during some period leading up to mid-1990 were of that flavor. See also {rotary debugger}; compare {ISO standard cup of tea}. :anti-idiotarianism: n. [very common] Opposition to idiots of all political stripes. First coined in the {blog} named Little Green Footballs as part of a post expressing disgust with inane responses to post-9/11 Islamic terrorism. Anti-idiotarian wrath has focused on Islamic terrorists and their sympathizers in the Western political left, but also routinely excoriated right-wing politicians backing repressive 'anti-terror` legislation and Christian religious figures who (in the blogosphere's view of the matter) have descended nearly to the level of jihad themselves. :AOL!: n. [Usenet] Common synonym for "Me, too!" alluding to the legendary propensity of America Online users to utter contentless "Me, too!" postings. The number of exclamation points following varies from zero to five or so. The pseudo-HTML Me, too! is also frequently seen. See also {September that never ended}. :app: /ap/, n. Short for `application program', as opposed to a systems program. Apps are what systems vendors are forever chasing developers to create for their environments so they can sell more boxes. Hackers tend not to think of the things they themselves run as apps; thus, in hacker parlance the term excludes compilers, program editors, games, and messaging systems, though a user would consider all those to be apps. (Broadly, an app is often a self-contained environment for performing some well-defined task such as `word processing'; hackers tend to prefer more general-purpose tools.) See {killer app}; oppose {tool}, {operating system}. :Archimedes: The world's first RISC microcomputer, available only in the British Commonwealth and europe. Built in 1987 in Great Britain by Acorn Computers, it was legendary for its use of the ARM-2 microprocessor as a CPU. Many a novice hacker in the Commonwealth first learnt his or her skills on the Archimedes, since it was specifically designed for use in schools and educational institutions. Owners of Archimedes machines are often still treated with awe and reverence. Familiarly, "archi". :arena: n. [common; Unix] The area of memory attached to a process by brk(2) and sbrk(2) and used by malloc(3) as dynamic storage. So named from a malloc: corrupt arena message emitted when some early versions detected an impossible value in the free block list. See {overrun screw}, {aliasing bug}, {memory leak}, {memory smash}, {smash the stack}. :arg: /arg/, n. Abbreviation for `argument' (to a function), used so often as to have become a new word (like `piano' from `pianoforte'). "The sine function takes 1 arg, but the arc-tangent function can take either 1 or 2 args." Compare {param}, {parm}, {var}. :ARMM: n. [acronym, `Automated Retroactive Minimal Moderation'] A Usenet {cancelbot} created by Dick Depew of Munroe Falls, Ohio. ARMM was intended to automatically cancel posts from anonymous-posting sites. Unfortunately, the robot's recognizer for anonymous postings triggered on its own automatically-generated control messages! Transformed by this stroke of programming ineptitude into a monster of Frankensteinian proportions, it broke loose on the night of March 30, 1993 and proceeded to {spam} news.admin.policy with a recursive explosion of over 200 messages. ARMM's bug produced a recursive {cascade} of messages each of which mechanically added text to the ID and Subject and some other headers of its parent. This produced a flood of messages in which each header took up several screens and each message ID and subject line got longer and longer and longer. Reactions varied from amusement to outrage. The pathological messages crashed at least one mail system, and upset people paying line charges for their Usenet feeds. One poster described the ARMM debacle as "instant Usenet history" (also establishing the term {despew}), and it has since been widely cited as a cautionary example of the havoc the combination of good intentions and incompetence can wreak on a network. The Usenet thread on the subject is archived here. Compare {Great Worm}; {sorcerer's apprentice mode}. See also {software laser}, {network meltdown}. :armor-plated: n. Syn. for {bulletproof}. :asbestos: adj. [common] Used as a modifier to anything intended to protect one from {flame}s; also in other highly {flame}-suggestive usages. See, for example, {asbestos longjohns} and {asbestos cork award}. :asbestos cork award: n. Once, long ago at MIT, there was a {flamer} so consistently obnoxious that another hacker designed, had made, and distributed posters announcing that said flamer had been nominated for the asbestos cork award. (Any reader in doubt as to the intended application of the cork should consult the etymology under {flame}.) Since then, it is agreed that only a select few have risen to the heights of bombast required to earn this dubious dignity -- but there is no agreement on which few. :asbestos longjohns: n. Notional garments donned by {Usenet} posters just before emitting a remark they expect will elicit {flamage}. This is the most common of the {asbestos} coinages. Also asbestos underwear, asbestos overcoat, etc. :ASCII: /as´kee/, n. [originally an acronym (American Standard Code for Information Interchange) but now merely conventional] The predominant character set encoding of present-day computers. The standard version uses 7 bits for each character, whereas most earlier codes (including early drafts of ASCII prior to June 1961) used fewer. This change allowed the inclusion of lowercase letters -- a major {win} -- but it did not provide for accented letters or any other letterforms not used in English (such as the German sharp-S ß. or the ae-ligature æ which is a letter in, for example, Norwegian). It could be worse, though. It could be much worse. See {EBCDIC} to understand how. A history of ASCII and its ancestors is at http://www.wps.com/texts/codes/index.html. Computers are much pickier and less flexible about spelling than humans; thus, hackers need to be very precise when talking about characters, and have developed a considerable amount of verbal shorthand for them. Every character has one or more names -- some formal, some concise, some silly. Common jargon names for ASCII characters are collected here. See also individual entries for {bang}, {excl}, {open}, {ques}, {semi}, {shriek}, {splat}, {twiddle}, and {Yu-Shiang Whole Fish}. This list derives from revision 2.3 of the Usenet ASCII pronunciation guide. Single characters are listed in ASCII order; character pairs are sorted in by first member. For each character, common names are given in rough order of popularity, followed by names that are reported but rarely seen; official ANSI/CCITT names are surrounded by brokets: <>. Square brackets mark the particularly silly names introduced by {INTERCAL}. The abbreviations "l/r" and "o/c" stand for left/right and "open/close" respectively. Ordinary parentheticals provide some usage information. ! Common: {bang} ; pling; excl; not; shriek; ball-bat; .

Rare: ; gozinta; thru; pipesinta (last three from UNIX); [spike]. ~ Common: ; squiggle; {twiddle} ; not. Rare: approx; wiggle; swung dash; enyay; [sqiggle (sic)]. The pronunciation of # as `pound' is common in the U.S. but a bad idea; {Commonwealth Hackish} has its own, rather more apposite use of `pound sign' (confusingly, on British keyboards the £ happens to replace #; thus Britishers sometimes call # on a U.S.-ASCII keyboard `pound', compounding the American error). The U.S. usage derives from an old-fashioned commercial practice of using a # suffix to tag pound weights on bills of lading. The character is usually pronounced `hash' outside the U.S. There are more culture wars over the correct pronunciation of this character than any other, which has led to the {ha ha only serious} suggestion that it be pronounced "shibboleth" (see Judges 12:6 in an Old Testament or Tanakh). The `uparrow' name for circumflex and `leftarrow' name for underline are historical relics from archaic ASCII (the 1963 version), which had these graphics in those character positions rather than the modern punctuation characters. The `swung dash' or `approximation' sign (?1) is not quite the same as tilde ~ in typeset material, but the ASCII tilde serves for both (compare {angle brackets}). Some other common usages cause odd overlaps. The #, $, >, and & characters, for example, are all pronounced "hex" in different communities because various assemblers use them as a prefix tag for hexadecimal constants (in particular, # in many assembler-programming cultures, $ in the 6502 world, > at Texas Instruments, and & on the BBC Micro, Sinclair, and some Z80 machines). See also {splat}. The inability of ASCII text to correctly represent any of the world's other major languages makes the designers' choice of 7 bits look more and more like a serious {misfeature} as the use of international networks continues to increase (see {software rot}). Hardware and software from the U.S. still tends to embody the assumption that ASCII is the universal character set and that characters have 7 bits; this is a major irritant to people who want to use a character set suited to their own languages. Perversely, though, efforts to solve this problem by proliferating `national' character sets produce an evolutionary pressure to use a smaller subset common to all those in use. :ASCII art: n. The fine art of drawing diagrams using the ASCII character set (mainly |, -, /, \, and +). Also known as character graphics or ASCII graphics; see also {boxology}. Here is a serious example: o----)||(--+--|<----+ +---------o + D O L )||( | | | C U A I )||( +-->|-+ | +-\/\/-+--o - T C N )||( | | | | P E )||( +-->|-+--)---+--|(--+-o U )||( | | | GND T o----)||(--+--|<----+----------+ A power supply consisting of a full wave rectifier circuit feeding a capacitor input filter circuit And here are some very silly examples: |\/\/\/| ____/| ___ |\_/| ___ | | \ o.O| ACK! / \_ |` '| _/ \ | | =(_)= THPHTH! / \/ \/ \ | (o)(o) U / \ C _) (__) \/\/\/\ _____ /\/\/\/ | ,___| (oo) \/ \/ | / \/-------\ U (__) /____\ || | \ /---V `v'- oo ) / \ ||---W|| * * |--| || |`. |_/\ //-o-\\ ____---=======---____ ====___\ /.. ..\ /___==== Klingons rule OK! // ---\__O__/--- \\ \_\ /_/ There is an important subgenre of ASCII art that puns on the standard character names in the fashion of a rebus. +--------------------------------------------------------+ | ^^^^^^^^^^^^ | | ^^^^^^^^^^^ ^^^^^^^^^ | | ^^^^^^^^^^^^^ ^^^^^^^^^^^^^ | | ^^^^^^^ B ^^^^^^^^^ | | ^^^^^^^^^ ^^^ ^^^^^^^^^^^^^^ | +--------------------------------------------------------+ " A Bee in the Carrot Patch " Within humorous ASCII art, there is for some reason an entire flourishing subgenre of pictures of silly cows.

There are not many large examples of this; perhaps the best known is the ASCII animation of the original Star Wars movie at http://www.asciimation.co.nz/. There is a newsgroup, alt.ascii-art, devoted to this genre; however, see also {warlording}. :ASCIIbetical order: /as´kee·be'·t@·kl or´dr/, adj.,n. Used to indicate that data is sorted in ASCII collated order rather than alphabetical order. This lexicon is sorted in something close to ASCIIbetical order, but with case ignored and entries beginning with non-alphabetic characters moved to the beginning. "At my video store, they used their computer to sort the videos into ASCIIbetical order, so I couldn't find Crocodile Dundee until I thought to look before 2001 and 48 Hours!" :astroturfing: n. 1. The use of paid shills to create the impression of a popular movement, through means like letters to newspapers from soi-disant `concerned citizens', paid opinion pieces, and the formation of grass-roots lobbying groups that are actually funded by a PR group (AstroTurf is fake grass; hence the term). 2. What an individual posting to a public forum under an assumed name is said to be doing. This term became common among hackers after it came to light in early 1998 that Microsoft had attempted to use such tactics to forestall the U.S. Department of Justice's antitrust action against the company. The maneuver backfired horribly, angering a number of state attorneys-general enough to induce them to go public with plans to join the Federal suit. It also set anybody defending Microsoft on the net for the accusation "You're just astroturfing!". :atomic: adj. [from Gk. atomos, indivisible] 1. Indivisible; cannot be split up. For example, an instruction may be said to do several things `atomically', i.e., all the things are done immediately, and there is no chance of the instruction being half-completed or of another being interspersed. Used esp. to convey that an operation cannot be screwed up by interrupts. "This routine locks the file and increments the file's semaphore atomically." 2. [primarily techspeak] Guaranteed to complete successfully or not at all, usu. refers to database transactions. If an error prevents a partially-performed transaction from proceeding to completion, it must be "backed out", as the database must not be left in an inconsistent state. Computer usage, in either of the above senses, has none of the connotations that `atomic' has in mainstream English (i.e. of particles of matter, nuclear explosions etc.). :attoparsec: n. About an inch. atto- is the standard SI prefix for multiplication by 10^-18. A parsec (parallax-second) is 3.26 light-years; an attoparsec is thus 3.26 × 10^-18 light years, or about 3.1 cm (thus, 1 attoparsec/{microfortnight} equals about 1 inch/sec). This unit is reported to be in use (though probably not very seriously) among hackers in the U.K. See {micro-}. :Aunt Tillie: n. [linux-kernel mailing list] The archetypal non-technical user, one's elderly and scatterbrained maiden aunt. Invoked in discussions of usability for people who are not hackers and geeks; one sees references to the "Aunt Tillie test". :AUP: /A·U·P/ Abbreviation, "Acceptable Use Policy". The policy of a given ISP which sets out what the ISP considers to be (un)acceptable uses of its Internet resources. :autobogotiphobia: /aw´toh·boh·got`@·foh´bee·@/ n. See {bogotify}. :autoconfiscate: To set up or modify a source-code {distribution} so that it configures and builds using the GNU project's autoconf/automake/libtools suite. Among open-source hackers, a mere running binary of a program is not considered a full release; what's interesting is a source tree that can be built into binaries using standard tools. Since the mid-1990s, autoconf and friends been the standard way to adapt a distribution for portability so that it can be built on multiple operating systems without change. :automagically: /aw·toh·maj´i·klee/, adv. Automatically, but in a way that, for some reason (typically because it is too complicated, or too ugly, or perhaps even too trivial), the speaker doesn't feel like explaining to you. See {magic}. "The C-INTERCAL compiler generates C, then automagically invokes cc(1) to produce an executable." This term is quite old, going back at least to the mid-70s in jargon and probably much earlier. The word `automagic' occurred in advertising (for a shirt-ironing gadget) as far back as the late 1940s. :avatar: n. [in Hindu mythology, the incarnation of a god] 1. Among people working on virtual reality and {cyberspace} interfaces, an avatar is an icon or representation of a user in a shared virtual reality. The term is sometimes used on {MUD}s. 2. [CMU, Tektronix] {root}, {superuser}. There are quite a few Unix machines on which the name of the superuser account is `avatar' rather than `root'. This quirk was originated by a CMU hacker who found the terms root and superuser unimaginative, and thought `avatar' might better impress people with the responsibility they were accepting. :awk: /awk/ 1. n. [Unix techspeak] An interpreted language for massaging text data developed by Alfred Aho, Peter Weinberger, and Brian Kernighan (the name derives from their initials). It is characterized by C-like syntax, a declaration-free approach to variable typing and declarations, associative arrays, and field-oriented text processing. See also {Perl}. 2. n. Editing term for an expression awkward to manipulate through normal {regexp} facilities (for example, one containing a {newline}). 3. vt. To process data using awk(1).

Wrong. :B1FF: /bif/, BIFF, n. The most famous {pseudo}, and the prototypical {newbie}. Articles from B1FF feature all uppercase letters sprinkled liberally with bangs, typos, `cute' misspellings (EVRY BUDY LUVS GOOD OLD BIFF CUZ KØØL DOOD AN HE RITES REEL AWESUM THINGZ IN CAPITULL LETTRS LIKE THIS!!!), use (and often misuse) of fragments of {talk mode} abbreviations, a long {sig block} (sometimes even a {doubled sig}), and unbounded naivete. B1FF posts articles using his elder brother's VIC-20. B1FF's location is a mystery, as his articles appear to come from a variety of sites. However, BITNET seems to be the most frequent origin. The theory that B1FF is a denizen of BITNET is supported by B1FF's (unfortunately invalid) electronic mail address: B1FF@BIT.NET. [1993: Now It Can Be Told! My spies inform me that B1FF was originally created by Joe Talmadge , also the author of the infamous and much-plagiarized "Flamer's Bible". The BIFF filter he wrote was later passed to Richard Sexton, who posted BIFFisms much more widely. Versions have since been posted for the amusement of the net at large. See also {Jeff K.} --ESR] :B5: // [common] Abbreviation for "Babylon 5", a science-fiction TV series as revered among hackers as was the original Star Trek. :back door: n. [common] A hole in the security of a system deliberately left in place by designers or maintainers. The motivation for such holes is not always sinister; some operating systems, for example, come out of the box with privileged accounts intended for use by field service technicians or the vendor's maintenance programmers. Syn. {trap door}; may also be called a wormhole. See also {iron box}, {cracker}, {worm}, {logic bomb}. Historically, back doors have often lurked in systems longer than anyone expected or planned, and a few have become widely known. Ken Thompson's 1983 Turing Award lecture to the ACM admitted the existence of a back door in early Unix versions that may have qualified as the most fiendishly clever security hack of all time. In this scheme, the C compiler contained code that would recognize when the login command was being recompiled and insert some code recognizing a password chosen by Thompson, giving him entry to the system whether or not an account had been created for him. Normally such a back door could be removed by removing it from the source code for the compiler and recompiling the compiler. But to recompile the compiler, you have to use the compiler -- so Thompson also arranged that the compiler would recognize when it was compiling a version of itself, and insert into the recompiled compiler the code to insert into the recompiled login the code to allow Thompson entry -- and, of course, the code to recognize itself and do the whole thing again the next time around! And having done this once, he was then able to recompile the compiler from the original sources; the hack perpetuated itself invisibly, leaving the back door in place and active but with no trace in the sources. The Turing lecture that reported this truly moby hack was later published as "Reflections on Trusting Trust", Communications of the ACM 27, 8 (August 1984), pp. 761--763 (text available at http://www.acm.org/classics/). Ken Thompson has since confirmed that this hack was implemented and that the Trojan Horse code did appear in the login binary of a Unix Support group machine. Ken says the crocked compiler was never distributed. Your editor has heard two separate reports that suggest that the crocked login did make it out of Bell Labs, notably to BBN, and that it enabled at least one late-night login across the network by someone using the login name "kt". :backbone cabal: n. A group of large-site administrators who pushed through the {Great Renaming} and reined in the chaos of {Usenet} during most of the 1980s. During most of its lifetime, the Cabal (as it was sometimes capitalized) steadfastly denied its own existence; it was almost obligatory for anyone privy to their secrets to respond "There is no Cabal" whenever the existence or activities of the group were speculated on in public. The result of this policy was an attractive aura of mystery. Even a decade after the cabal {mailing list} disbanded in late 1988 following a bitter internal catfight, many people believed (or claimed to believe) that it had not actually disbanded but only gone deeper underground with its power intact. This belief became a model for various paranoid theories about various Cabals with dark nefarious objectives beginning with taking over the Usenet or Internet. These paranoias were later satirized in ways that took on a life of their own. See {Eric Conspiracy} for one example. See {NANA} for the subsequent history of "the Cabal". :backbone site: n.,obs. Formerly, a key Usenet and email site, one that processes a large amount of third-party traffic, especially if it is the home site of any of the regional coordinators for the Usenet maps. Notable backbone sites as of early 1993, when this sense of the term was beginning to pass out of general use due to wide availability of cheap Internet connections, included uunet and the mail machines at Rutgers University, UC Berkeley, {DEC}'s Western Research Laboratories, Ohio State University, and the University of Texas. Compare {leaf site}. [2001 update: This term has passed into history. The UUCP network world that gave it meaning is gone; everyone is on the Internet now and network traffic is distributed in very different patterns. Today one might see references to a "backbone router" instead --ESR] :backgammon: See {bignum} (sense 3), {moby} (sense 4), and {pseudoprime}. :background: n.,adj.,vt. [common] To do a task in background is to do it whenever {foreground} matters are not claiming your undivided attention, and to background something means to relegate it to a lower priority. "For now, we'll just print a list of nodes and links; I'm working on the graph-printing problem in background." Note that this implies ongoing activity but at a reduced level or in spare time, in contrast to mainstream `back burner' (which connotes benign neglect until some future resumption of activity). Some people prefer to use the term for processing that they have queued up for their unconscious minds (a tack that one can often fruitfully take upon encountering an obstacle in creative work). Compare {amp off}, {slopsucker}. Technically, a task running in background is detached from the terminal where it was started (and often running at a lower priority); oppose {foreground}. Nowadays this term is primarily associated with {Unix}, but it appears to have been first used in this sense on OS/360. :backreference: n. 1. In a regular expression or pattern match, the text which was matched within grouping parentheses 2. The part of the pattern which refers back to the matched text. 3. By extension, anything which refers back to something which has been seen or discussed before. "When you said `she' just now, who were you backreferencing?" :backronym: n. [portmanteau of back + acronym] A word interpreted as an acronym that was not originally so intended. This is a special case of what linguists call back formation. Examples are given under {recursive acronym} (Cygnus), {Acme}, and {mung}. Discovering backronyms is a common form of wordplay among hackers. Compare {retcon}. :backward combatability: /bak´w@rd k@m·bat'@·bil'@·tee/, n. [CMU, Tektronix: from backward compatibility] A property of hardware or software revisions in which previous protocols, formats, layouts, etc. are irrevocably discarded in favor of `new and improved' protocols, formats, and layouts, leaving the previous ones not merely deprecated but actively defeated. (Too often, the old and new versions cannot definitively be distinguished, such that lingering instances of the previous ones yield crashes or other infelicitous effects, as opposed to a simple "version mismatch" message.) A backwards compatible change, on the other hand, allows old versions to coexist without crashes or error messages, but too many major changes incorporating elaborate backwards compatibility processing can lead to extreme {software bloat}. See also {flag day}. :BAD: /B·A·D/, adj. [IBM: acronym, "Broken As Designed"] Said of a program that is {bogus} because of bad design and misfeatures rather than because of bugginess. See {working as designed}. :Bad and Wrong: adj. [Durham, UK] Said of something that is both badly designed and wrongly executed. This common term is the prototype of, and is used by contrast with, three less common terms -- Bad and Right (a kludge, something ugly but functional); Good and Wrong (an overblown GUI or other attractive nuisance); and (rare praise) Good and Right. These terms entered common use at Durham c.1994 and may have been imported from elsewhere; they are also in use at Oxford, and the emphatic form "Evil and Bad and Wrong" (abbreviated EBW) is reported from there. There are standard abbreviations: they start with B&R, a typo for "Bad and Wrong". Consequently, B&W is actually "Bad and Right", G&R = "Good and Wrong", and G&W = "Good and Right". Compare {evil and rude}, {Good Thing}, {Bad Thing}. :Bad Thing: n. [very common; always pronounced as if capitalized. Orig. fr. the 1930 Sellar & Yeatman parody of British history 1066 And All That, but well-established among hackers in the U.S. as well.] Something that can't possibly result in improvement of the subject. This term is always capitalized, as in "Replacing all of the DSL links with bicycle couriers would be a Bad Thing". Oppose {Good Thing}. British correspondents confirm that {Bad Thing} and {Good Thing} (and prob. therefore {Right Thing} and {Wrong Thing}) come from the book referenced in the etymology, which discusses rulers who were Good Kings but Bad Things. This has apparently created a mainstream idiom on the British side of the pond. It is very common among American hackers, but not in mainstream usage in the U.S. Compare {Bad and Wrong}. :bag on the side: n. [prob. originally related to a colostomy bag] An extension to an established hack that is supposed to add some functionality to the original. Usually derogatory, implying that the original was being overextended and should have been thrown away, and the new product is ugly, inelegant, or bloated. Also v. phrase, "to hang a bag on the side [of]". "C++? That's just a bag on the side of C ...." "They want me to hang a bag on the side of the accounting system." :bagbiter: /bag´bi:t·@r/, n. 1. Something, such as a program or a computer, that fails to work, or works in a remarkably clumsy manner. "This text editor won't let me make a file with a line longer than 80 characters! What a bagbiter!" 2. A person who has caused you some trouble, inadvertently or otherwise, typically by failing to program the computer properly. Synonyms: {loser}, {cretin}, {chomper}. 3. bite the bag vi. To fail in some manner. "The computer keeps crashing every five minutes." "Yes, the disk controller is really biting the bag." The original loading of these terms was almost undoubtedly obscene, possibly referring to a douche bag or the scrotum (we have reports of "Bite the douche bag!" being used as a taunt at MIT 1970-1976, and we have another report that "Bite the bag!" was in common use at least as early as 1965), but in their current usage they have become almost completely sanitized. :bagbiting: adj. [MIT; now rare] Having the quality of a {bagbiter}. "This bagbiting system won't let me compute the factorial of a negative number." Compare {losing}, {cretinous}, {bletcherous}, barfucious' (under {barfulous}) and chomping (under {chomp}). :baggy pantsing: v. [Georgia Tech] A "baggy pantsing" is used to reprimand hackers who incautiously leave their terminals unlocked. The affected user will come back to find a post from them on internal newsgroups discussing exactly how baggy their pants are, an accepted stand-in for "unattentive user who left their work unprotected in the clusters". A properly-done baggy pantsing is highly mocking and humorous. It is considered bad form to post a baggy pantsing to off-campus newsgroups or the more technical, serious groups. A particularly nice baggy pantsing may be "claimed" by immediately quoting the message in full, followed by your {sig block}; this has the added benefit of keeping the embarassed victim from being able to delete the post. Interesting baggy-pantsings have been done involving adding commands to login scripts to repost the message every time the unlucky user logs in; Unix boxes on the residential network, when cracked, oftentimes have their homepages replaced (after being politely backed-up to another file) with a baggy-pants message; .plan files are also occasionally targeted. Usage: "Prof. Greenlee fell asleep in the Solaris cluster again; we baggy-pantsed him to git.cc.class.2430.flame." Compare {derf}. :balloonian variable: n. [Commodore users; perh. a deliberate phonetic mangling of boolean variable?] Any variable that doesn't actually hold or control state, but must nevertheless be declared, checked, or set. A typical balloonian variable started out as a flag attached to some environment feature that either became obsolete or was planned but never implemented. Compatibility concerns (or politics attached to same) may require that such a flag be treated as though it were {live}. :bamf: /bamf/ 1. [from X-Men comics; originally "bampf"] interj. Notional sound made by a person or object teleporting in or out of the hearer's vicinity. Often used in {virtual reality} (esp. {MUD}) electronic {fora} when a character wishes to make a dramatic entrance or exit. 2. The sound of magical transformation, used in virtual reality {fora} like MUDs. 3. In MUD circles, "bamf" is also used to refer to the act by which a MUD server sends a special notification to the MUD client to switch its connection to another server ("I'll set up the old site to just bamf people over to our new location."). 4. Used by MUDders on occasion in a more general sense related to sense 3, to refer to directing someone to another location or resource ("A user was asking about some technobabble so I bamfed them to http://www.catb.org/~esr/jargon/".) :banana problem: n. [from the story of the little girl who said "I know how to spell `banana', but I don't know when to stop"]. Not knowing where or when to bring a production to a close (compare {fencepost error}). One may say there is a banana problem of an algorithm with poorly defined or incorrect termination conditions, or in discussing the evolution of a design that may be succumbing to featuritis (see also {creeping elegance}, {creeping featuritis}). See item 176 under {HAKMEM}, which describes a banana problem in a {Dissociated Press} implementation. Also, see {one-banana problem} for a superficially similar but unrelated usage. :bandwidth: n. 1. [common] Used by hackers (in a generalization of its technical meaning) as the volume of information per unit time that a computer, person, or transmission medium can handle. "Those are amazing graphics, but I missed some of the detail -- not enough bandwidth, I guess." Compare {low-bandwidth}; see also {brainwidth}. This generalized usage began to go mainstream after the Internet population explosion of 1993-1994. 2. Attention span. 3. On {Usenet}, a measure of network capacity that is often wasted by people complaining about how items posted by others are a waste of bandwidth. :bang: 1. n. Common spoken name for ! (ASCII 0100001), especially when used in pronouncing a {bang path} in spoken hackish. In {elder days} this was considered a CMUish usage, with MIT and Stanford hackers preferring {excl} or {shriek}; but the spread of Unix has carried `bang' with it (esp. via the term {bang path}) and it is now certainly the most common spoken name for !. Note that it is used exclusively for non-emphatic written !; one would not say "Congratulations bang" (except possibly for humorous purposes), but if one wanted to specify the exact characters "foo!" one would speak "Eff oh oh bang". See {shriek}, {ASCII}. 2. interj. An exclamation signifying roughly "I have achieved enlightenment!", or "The dynamite has cleared out my brain!" Often used to acknowledge that one has perpetrated a {thinko} immediately after one has been called on it. :bang on: vt. To stress-test a piece of hardware or software: "I banged on the new version of the simulator all day yesterday and it didn't crash once. I guess it is ready for release." The term {pound on} is synonymous. :bang path: n. [now historical] An old-style UUCP electronic-mail address specifying hops to get from some assumed-reachable location to the addressee, so called because each {hop} is signified by a {bang} sign. Thus, for example, the path ...!bigsite!foovax!barbox!me directs people to route their mail to machine bigsite (presumably a well-known location accessible to everybody) and from there through the machine foovax to the account of user me on barbox. In the bad old days of not so long ago, before autorouting mailers became commonplace, people often published compound bang addresses using the { } convention (see {glob}) to give paths from several big machines, in the hopes that one's correspondent might be able to get mail to one of them reliably (example: ...!{seismo, ut-sally, ihnp4!rice!beta!gamma!me}). Bang paths of 8 to 10 hops were not uncommon. Late-night dial-up UUCP links would cause week-long transmission times. Bang paths were often selected by both transmission time and reliability, as messages would often get lost. See {the network} and {sitename}. :banner: n. 1. A top-centered graphic on a web page. Esp. used in {banner ad}. 2. On interactive software, a first screen containing a logo and/or author credits and/or a copyright notice. 3. The title page added to printouts by most print spoolers (see {spool}). Typically includes user or account ID information in very large character-graphics capitals. Also called a burst page, because it indicates where to burst (tear apart) fanfold paper to separate one user's printout from the next. 4. A similar printout generated (typically on multiple pages of fan-fold paper) from user-specified text, e.g., by a program such as Unix's banner({1,6)}. :banner ad: n. Any of the annoying graphical advertisements that span the tops of way too many Web pages. :banner site: n. [warez d00dz] An FTP site storing pirated files where one must first click on several banners and/or subscribe to various `free' services, usually generating some form of revenues for the site owner, to be able to access the site. More often than not, the username/password painfully obtained by clicking on banners and subscribing to bogus services or mailing lists turns out to be non-working or gives access to a site that always responds busy. See {ratio site}, {leech mode}. :bar: /bar/, n. 1. [very common] The second {metasyntactic variable}, after {foo} and before {baz}. "Suppose we have two functions: FOO and BAR. FOO calls BAR...." 2. Often appended to {foo} to produce {foobar}. :bare metal: n. 1. [common] New computer hardware, unadorned with such snares and delusions as an {operating system}, an {HLL}, or even assembler. Commonly used in the phrase programming on the bare metal, which refers to the arduous work of {bit bashing} needed to create these basic tools for a new machine. Real bare-metal programming involves things like building boot proms and BIOS chips, implementing basic monitors used to test device drivers, and writing the assemblers that will be used to write the compiler back ends that will give the new machine a real development environment. 2. "Programming on the bare metal" is also used to describe a style of {hand-hacking} that relies on bit-level peculiarities of a particular hardware design, esp. tricks for speed and space optimization that rely on crocks such as overlapping instructions (or, as in the famous case described in The Story of Mel' (in Appendix A), interleaving of opcodes on a magnetic drum to minimize fetch delays due to the device's rotational latency). This sort of thing has become rare as the relative costs of programming time and machine resources have changed, but is still found in heavily constrained environments such as industrial embedded systems. See {Real Programmer}. :barf: /barf/, n.,v. [common; from mainstream slang meaning `vomit'] 1. interj. Term of disgust. This is the closest hackish equivalent of the Valspeak "gag me with a spoon". (Like, euwww!) See {bletch}. 2. vi. To say "Barf!" or emit some similar expression of disgust. "I showed him my latest hack and he barfed" means only that he complained about it, not that he literally vomited. 3. vi. To fail to work because of unacceptable input, perhaps with a suitable error message, perhaps not. Examples: "The division operation barfs if you try to divide by 0." (That is, the division operation checks for an attempt to divide by zero, and if one is encountered it causes the operation to fail in some unspecified, but generally obvious, manner.) "The text editor barfs if you try to read in a new file before writing out the old one." See {choke}. In Commonwealth Hackish, barf is generally replaced by `puke' or `vom'. {barf} is sometimes also used as a {metasyntactic variable}, like {foo} or {bar}. :barfmail: n. Multiple {bounce message}s accumulating to the level of serious annoyance, or worse. The sort of thing that happens when an inter-network mail gateway goes down or wonky. :barfulation: /bar`fyoo·lay´sh@n/, interj. Variation of {barf} used around the Stanford area. An exclamation, expressing disgust. On seeing some particularly bad code one might exclaim, "Barfulation! Who wrote this, Quux?" :barfulous: /bar´fyoo·l@s/, adj. (alt.: barfucious, /bar-fyoo-sh@s/) Said of something that would make anyone barf, if only for esthetic reasons. :barn: n. [uncommon; prob. from the nuclear military] An unexpectedly large quantity of something: a unit of measurement. "Why is /var/adm taking up so much space?" "The logs have grown to several barns." The source of this is clear: when physicists were first studying nuclear interactions, the probability was thought to be proportional to the cross-sectional area of the nucleus (this probability is still called the cross-section). Upon experimenting, they discovered the interactions were far more probable than expected; the nuclei were "as big as a barn". The units for cross-sections were christened Barns, (10^-24 cm2) and the book containing cross-sections has a picture of a barn on the cover. :barney: n. In Commonwealth hackish, barney is to {fred} (sense #1) as {bar} is to {foo}. That is, people who commonly use fred as their first metasyntactic variable will often use barney second. The reference is, of course, to Fred Flintstone and Barney Rubble in the Flintstones cartoons. :baroque: adj. [common] Feature-encrusted; complex; gaudy; verging on excessive. Said of hardware or (esp.) software designs, this has many of the connotations of {elephantine} or {monstrosity} but is less extreme and not pejorative in itself. "Metafont even has features to introduce random variations to its letterform output. Now that is baroque!" See also {rococo}. :BASIC: /bay'·sic/, n. A programming language, originally designed for Dartmouth's experimental timesharing system in the early 1960s, which for many years was the leading cause of brain damage in proto-hackers. Edsger W. Dijkstra observed in Selected Writings on Computing: A Personal Perspective that "It is practically impossible to teach good programming style to students that have had prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration." This is another case (like {Pascal}) of the cascading {lossage} that happens when a language deliberately designed as an educational toy gets taken too seriously. A novice can write short BASIC programs (on the order of 10-20 lines) very easily; writing anything longer (a) is very painful, and (b) encourages bad habits that will make it harder to use more powerful languages well. This wouldn't be so bad if historical accidents hadn't made BASIC so common on low-end micros in the 1980s. As it is, it probably ruined tens of thousands of potential wizards. [1995: Some languages called "BASIC" aren't quite this nasty any more, having acquired Pascal- and C-like procedures and control structures and shed their line numbers. --ESR] BASIC stands for "Beginner's All-purpose Symbolic Instruction Code". Earlier versions of this entry claiming this was a later {backronym} were incorrect. :batbelt: n. Many hackers routinely hang numerous devices such as pagers, cell-phones, personal organizers, leatherman multitools, pocket knives, flashlights, walkie-talkies, even miniature computers from their belts. When many of these devices are worn at once, the hacker's belt somewhat resembles Batman's utility belt; hence it is referred to as a batbelt. :batch: adj. 1. Non-interactive. Hackers use this somewhat more loosely than the traditional technical definitions justify; in particular, switches on a normally interactive program that prepare it to receive non-interactive command input are often referred to as batch mode switches. A batch file is a series of instructions written to be handed to an interactive program running in batch mode. 2. Performance of dreary tasks all at one sitting. "I finally sat down in batch mode and wrote out checks for all those bills; I guess they'll turn the electricity back on next week..." 3. batching up: Accumulation of a number of small tasks that can be lumped together for greater efficiency. "I'm batching up those letters to send sometime" "I'm batching up bottles to take to the recycling center." [crunchly-2.png] (The next cartoon in the Crunchly saga is 76-03-17:5-8) :bathtub curve: n. Common term for the curve (resembling an end-to-end section of one of those claw-footed antique bathtubs) that describes the expected failure rate of electronics with time: initially high, dropping to near 0 for most of the system's lifetime, then rising again as it `tires out'. See also {burn-in period}, {infant mortality}. :Batman factor: n. 1. An integer number representing the number of items hanging from a {batbelt}. In most settings, a Batman factor of more than 3 is not acceptable without odd stares and whispering. This encourages the hacker in question to choose items for the batbelt carefully to avoid awkward social situations, usually amongst non-hackers. 2. A somewhat more vaguely defined index of contribution to sense 1. Devices that are especially obtrusive, such as large, older model cell phones, "Pocket" PC devices and walkie talkies are said to have a high batman factor. Sleeker devices such as a later-model Palm or StarTac phone are prized for their low batman factor and lessened obtrusiveness and weight. :baud: /bawd/, n. [simplified from its technical meaning] n. Bits per second. Hence kilobaud or Kbaud, thousands of bits per second. The technical meaning is level transitions per second; this coincides with bps only for two-level modulation with no framing or stop bits. Most hackers are aware of these nuances but blithely ignore them. Historical note: baud was originally a unit of telegraph signalling speed, set at one pulse per second. It was proposed at the November, 1926 conference of the Comité Consultatif International Des Communications Télégraphiques as an improvement on the then standard practice of referring to line speeds in terms of words per minute, and named for Jean Maurice Emile Baudot (1845-1903), a French engineer who did a lot of pioneering work in early teleprinters. :baz: /baz/, n. 1. [common] The third {metasyntactic variable} "Suppose we have three functions: FOO, BAR, and BAZ. FOO calls BAR, which calls BAZ...." (See also {fum}) 2. interj. A term of mild annoyance. In this usage the term is often drawn out for 2 or 3 seconds, producing an effect not unlike the bleating of a sheep; /baaaaaaz/. 3. Occasionally appended to {foo} to produce `foobaz'. Earlier versions of this lexicon derived baz as a Stanford corruption of {bar}. However, Pete Samson (compiler of the {TMRC} lexicon) reports it was already current when he joined TMRC in 1958. He says "It came from Pogo. Albert the Alligator, when vexed or outraged, would shout `Bazz Fazz!' or `Rowrbazzle!' The club layout was said to model the (mythical) New England counties of Rowrfolk and Bassex (Rowrbazzle mingled with (Norfolk/Suffolk/Middlesex/Essex)." :bazaar: n.,adj. In 1997, after meditating on the success of {Linux} for three years, the Jargon File's own editor ESR wrote an analytical paper on hacker culture and development models titled The Cathedral and the Bazaar. The main argument of the paper was that {Brooks's Law} is not the whole story; given the right social machinery, debugging can be efficiently parallelized across large numbers of programmers. The title metaphor caught on (see also {cathedral}), and the style of development typical in the Linux community is now often referred to as the bazaar mode. Its characteristics include releasing code early and often, and actively seeking the largest possible pool of peer reviewers. After 1998, the evident success of this way of doing things became one of the strongest arguments for {open source}. :bboard: /bee´bord/, n. [contraction of `bulletin board'] 1. Any electronic bulletin board; esp. used of {BBS} systems running on personal micros, less frequently of a Usenet {newsgroup} (in fact, use of this term for a newsgroup generally marks one either as a {newbie} fresh in from the BBS world or as a real old-timer predating Usenet). 2. At CMU and other colleges with similar facilities, refers to campus-wide electronic bulletin boards. 3. The term physical bboard is sometimes used to refer to an old-fashioned, non-electronic cork-and-thumbtack memo board. At CMU, it refers to a particular one outside the CS Lounge. In either of senses 1 or 2, the term is usually prefixed by the name of the intended board (`the Moonlight Casino bboard' or `market bboard'); however, if the context is clear, the better-read bboards may be referred to by name alone, as in (at CMU) "Don't post for-sale ads on general". :BBS: /B·B·S/, n. [common; abbreviation, "Bulletin Board System"] An electronic bulletin board system; that is, a message database where people can log in and leave broadcast messages for others grouped (typically) into {topic group}s. The term was especially applied to the thousands of local BBS systems that operated during the pre-Internet microcomputer era of roughly 1980 to 1995, typically run by amateurs for fun out of their homes on MS-DOS boxes with a single modem line each. Fans of Usenet and Internet or the big commercial timesharing bboards such as CompuServe and GEnie tended to consider local BBSes the low-rent district of the hacker culture, but they served a valuable function by knitting together lots of hackers and users in the personal-micro world who would otherwise have been unable to exchange code at all. Post-Internet, BBSs are likely to be local newsgroups on an ISP; efficiency has increased but a certain flavor has been lost. See also {bboard}. :BCPL: //, n. [abbreviation, "Basic Combined Programming Language") A programming language developed by Martin Richards in Cambridge in 1967. It is remarkable for its rich syntax, small size of compiler (it can be run in 16k) and extreme portability. It reached break-even point at a very early stage, and was the language in which the original {hello world} program was written. It has been ported to so many different systems that its creator confesses to having lost count. It has only one data type (a machine word) which can be used as an integer, a character, a floating point number, a pointer, or almost anything else, depending on context. BCPL was a precursor of C, which inherited some of its features. :BDFL: [Python; common] Benevolent Dictator For Life. {Guido}, considered in his role as the project leader of {Python}. People who are feeling temporarily cheesed off by one of his decisions sometimes leave off the B. The mental image that goes with this, of a cigar-chomping caudillo in gold braid and sunglasses, is extremely funny to anyone who has ever met Guido in person. :beam: vt. [from Star Trek Classic's "Beam me up, Scotty!"] 1. To transfer {softcopy} of a file electronically; most often in combining forms such as beam me a copy or beam that over to his site. 2. Palm Pilot users very commonly use this term for the act of exchanging bits via the infrared links on their machines (this term seems to have originated with the ill-fated Newton Message Pad). Compare {blast}, {snarf}, {BLT}. :beanie key: n. [Mac users] See {command key}. :beep: n.,v. Syn. {feep}. This term is techspeak under MS-DOS/Windows and OS/2, and seems to be generally preferred among micro hobbyists. :Befunge: n. A worthy companion to {INTERCAL}; a computer language family which escapes the quotidian limitation of linear control flow and embraces program counters flying through multiple dimensions with exotic topologies. The Befunge home page is at http://www.catseye.mb.ca/esoteric/befunge/. :beige toaster: n. [obs.] An original Macintosh in the boxy beige case. See {toaster}; compare {Macintrash}, {maggotbox}. :bells and whistles: n. [common] Features added to a program or system to make it more {flavorful} from a hacker's point of view, without necessarily adding to its utility for its primary function. Distinguished from {chrome}, which is intended to attract users. "Now that we've got the basic program working, let's go back and add some bells and whistles." No one seems to know what distinguishes a bell from a whistle. The recognized emphatic form is "bells, whistles, and gongs". It used to be thought that this term derived from the toyboxes on theater organs. However, the "and gongs" strongly suggests a different origin, at sea. Before powered horns, ships routinely used bells, whistles, and gongs to signal each other over longer distances than voice can carry. [73-05-28.png] Sometimes `trouble' is spelled {bells and whistles}... (The next cartoon in the Crunchly saga is 73-06-04) :bells whistles and gongs: n. A standard elaborated form of {bells and whistles}; typically said with a pronounced and ironic accent on the `gongs'. :benchmark: n. [techspeak] An inaccurate measure of computer performance. "In the computer industry, there are three kinds of lies: lies, damn lies, and benchmarks." Well-known ones include Whetstone, Dhrystone, Rhealstone (see {h}), the Gabriel LISP benchmarks, the SPECmark suite, and LINPACK. See also {machoflops}, {MIPS}, {smoke and mirrors}. :Berkeley Quality Software: adj. (often abbreviated "BQS") Term used in a pejorative sense to refer to software that was apparently created by rather spaced-out hackers late at night to solve some unique problem. It usually has nonexistent, incomplete, or incorrect documentation, has been tested on at least two examples, and core dumps when anyone else attempts to use it. This term was frequently applied to early versions of the dbx(1) debugger. See also {Berzerkeley}. Note to British and Commonwealth readers: that's /berk´lee/, not /bark´lee/ as in British Received Pronunciation. :Berzerkeley: /b@r·zer´klee/, n. [from `berserk', via the name of a now-deceased record label; poss. originated by famed columnist Herb Caen] Humorous distortion of "Berkeley" used esp. to refer to the practices or products of the {BSD} Unix hackers. See {software bloat}, {Berkeley Quality Software}. Mainstream use of this term in reference to the cultural and political peculiarities of UC Berkeley as a whole has been reported from as far back as the 1960s. :beta: /bay´t@/, /be´t@/, /bee´t@/, n. 1. Mostly working, but still under test; usu. used with "in": in beta. In the {Real World}, hardware or software systems often go through two stages of release testing: Alpha (in-house) and Beta (out-house?). Beta releases are generally made to a group of lucky (or unlucky) trusted customers. 2. Anything that is new and experimental. "His girlfriend is in beta" means that he is still testing for compatibility and reserving judgment. 3. Flaky; dubious; suspect (since beta software is notoriously buggy). Historical note: More formally, to beta-test is to test a pre-release (potentially unreliable) version of a piece of software by making it available to selected (or self-selected) customers and users. This term derives from early 1960s terminology for product cycle checkpoints, first used at IBM but later standard throughout the industry. Alpha Test was the unit, module, or component test phase; Beta Test was initial system test. These themselves came from earlier A- and B-tests for hardware. The A-test was a feasibility and manufacturability evaluation done before any commitment to design and development. The B-test was a demonstration that the engineering model functioned as specified. The C-test (corresponding to today's beta) was the B-test performed on early samples of the production design, and the D test was the C test repeated after the model had been in production a while. :BFI: /B·F·I/, n. See {brute force and ignorance}. Also encountered in the variants BFMI, "brute force and massive ignorance" and BFBI "brute force and bloody ignorance". In some parts of the U.S. this abbreviation was probably reinforced by a company called Browning-Ferris Industries in the waste-management business; a large BFI logo in white-on-blue could be seen on the sides of garbage trucks. :BI: // Common written abbreviation for {Breidbart Index}. :bible: n. 1. One of a small number of fundamental source books such as {Knuth}, {K&R}, or the {Camel Book}. 2. The most detailed and authoritative reference for a particular language, operating system, or other complex software system. :BiCapitalization: n. The act said to have been performed on trademarks (such as {PostScript}, NeXT, {NeWS}, VisiCalc, FrameMaker, TK!solver, EasyWriter) that have been raised above the ruck of common coinage by nonstandard capitalization. Too many {marketroid} types think this sort of thing is really cute, even the 2,317th time they do it. Compare {studlycaps}, {InterCaps}. :biff: /bif/, vt. [now rare] To notify someone of incoming mail. From the BSD utility biff(1), which was in turn named after a friendly dog who used to chase frisbees in the halls at UCB while 4.2BSD was in development. There was a legend that it had a habit of barking whenever the mailman came, but the author of biff says this is not true. No relation to {B1FF}. :big iron: n. [common] Large, expensive, ultra-fast computers. Used generally of {number-crunching} supercomputers, but can include more conventional big commercial IBMish mainframes. Term of approval; compare {heavy metal}, oppose {dinosaur}. :Big Red Switch: n. [IBM] The power switch on a computer, esp. the `Emergency Pull' switch on an IBM {mainframe} or the power switch on an IBM PC where it really is large and red. "This !@%$% {bitty box} is hung again; time to hit the Big Red Switch." Sources at IBM report that, in tune with the company's passion for {TLA}s, this is often abbreviated as BRS (this has also become established on FidoNet and in the PC {clone} world). It is alleged that the emergency pull switch on an IBM 360/91 actually fired a non-conducting bolt into the main power feed; the BRSes on more recent mainframes physically drop a block into place so that they can't be pushed back in. People get fired for pulling them, especially inappropriately (see also {molly-guard}). Compare {power cycle}, {three-finger salute}; see also {scram switch}. :Big Room: n. (Also Big Blue Room) The extremely large room with the blue ceiling and intensely bright light (during the day) or black ceiling with lots of tiny night-lights (during the night) found outside all computer installations. "He can't come to the phone right now, he's somewhere out in the Big Room." :big win: n. 1. [common] Major success. 2. [MIT] Serendipity. "Yes, those two physicists discovered high-temperature superconductivity in a batch of ceramic that had been prepared incorrectly according to their experimental schedule. Small mistake; big win!" See {win big}. :big-endian: adj. [common; From Swift's Gulliver's Travels via the famous paper On Holy Wars and a Plea for Peace by Danny Cohen, USC/ISI IEN 137, dated April 1, 1980] 1. Describes a computer architecture in which, within a given multi-byte numeric representation, the most significant byte has the lowest address (the word is stored `big-end-first'). Most processors, including the IBM 370 family, the {PDP-10}, the Motorola microprocessor families, and most of the various RISC designs are big-endian. Big-endian byte order is also sometimes called network order. See {little-endian}, {middle-endian}, {NUXI problem}, {swab}. 2. An Internet address the wrong way round. Most of the world follows the Internet standard and writes email addresses starting with the name of the computer and ending up with the name of the country. In the U.K.: the Joint Academic Networking Team had decided to do it the other way round before the Internet domain standard was established. Most gateway sites have {ad-hockery} in their mailers to handle this, but can still be confused. In particular, the address me@uk.ac.bris.pys.as could be interpreted in JANET's big-endian way as one in the U.K. (domain uk) or in the standard little-endian way as one in the domain as (American Samoa) on the opposite side of the world. :bignum: /big´nuhm/, n. [common; orig. from MIT MacLISP] 1. [techspeak] A multiple-precision computer representation for very large integers. 2. More generally, any very large number. "Have you ever looked at the United States Budget? There's bignums for you!" 3. [Stanford] In backgammon, large numbers on the dice especially a roll of double fives or double sixes (compare {moby}, sense 4). See also {El Camino Bignum}. Sense 1 may require some explanation. Most computer languages provide a kind of data called integer, but such computer integers are usually very limited in size; usually they must be smaller than 2^31 (2,147,483,648). If you want to work with numbers larger than that, you have to use floating-point numbers, which are usually accurate to only six or seven decimal places. Computer languages that provide bignums can perform exact calculations on very large numbers, such as 1000! (the factorial of 1000, which is 1000 times 999 times 998 times ... times 2 times 1). For example, this value for 1000! was computed by the MacLISP system using bignums: 40238726007709377354370243392300398571937486421071 46325437999104299385123986290205920442084869694048 00479988610197196058631666872994808558901323829669 94459099742450408707375991882362772718873251977950 59509952761208749754624970436014182780946464962910 56393887437886487337119181045825783647849977012476 63288983595573543251318532395846307555740911426241 74743493475534286465766116677973966688202912073791 43853719588249808126867838374559731746136085379534 52422158659320192809087829730843139284440328123155 86110369768013573042161687476096758713483120254785 89320767169132448426236131412508780208000261683151 02734182797770478463586817016436502415369139828126 48102130927612448963599287051149649754199093422215 66832572080821333186116811553615836546984046708975 60290095053761647584772842188967964624494516076535 34081989013854424879849599533191017233555566021394 50399736280750137837615307127761926849034352625200 01588853514733161170210396817592151090778801939317 81141945452572238655414610628921879602238389714760 88506276862967146674697562911234082439208160153780 88989396451826324367161676217916890977991190375403 12746222899880051954444142820121873617459926429565 81746628302955570299024324153181617210465832036786 90611726015878352075151628422554026517048330422614 39742869330616908979684825901254583271682264580665 26769958652682272807075781391858178889652208164348 34482599326604336766017699961283186078838615027946 59551311565520360939881806121385586003014356945272 24206344631797460594682573103790084024432438465657 24501440282188525247093519062092902313649327349756 55139587205596542287497740114133469627154228458623 77387538230483865688976461927383814900140767310446 64025989949022222176590433990188601856652648506179 97023561938970178600408118897299183110211712298459 01641921068884387121855646124960798722908519296819 37238864261483965738229112312502418664935314397013 74285319266498753372189406942814341185201580141233 44828015051399694290153483077644569099073152433278 28826986460278986432113908350621709500259738986355 42771967428222487575867657523442202075736305694988 25087968928162753848863396909959826280956121450994 87170124451646126037902930912088908694202851064018 21543994571568059418727489980942547421735824010636 77404595741785160829230135358081840096996372524230 56085590370062427124341690900415369010593398383577 79394109700277534720000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000. :bigot: n. [common] A person who is religiously attached to a particular computer, language, operating system, editor, or other tool (see {religious issues}). Usually found with a specifier; thus, Cray bigot, ITS bigot, APL bigot, VMS bigot, Berkeley bigot. Real bigots can be distinguished from mere partisans or zealots by the fact that they refuse to learn alternatives even when the march of time and/or technology is threatening to obsolete the favored tool. It is truly said "You can tell a bigot, but you can't tell him much." Compare {weenie}, {Amiga Persecution Complex}. :bikeshedding: [originally BSD, now common] Technical disputes over minor, marginal issues conducted while more serious ones are being overlooked. The implied image is of people arguing over what color to paint the bicycle shed while the house is not finished. :binary four: n. [Usenet] The finger, in the sense of digitus impudicus. This comes from an analogy between binary and the hand, i.e. 1=00001=thumb, 2=00010=index finger, 3=00011=index and thumb, 4=00100. Considered silly. Prob. from humorous derivative of {finger}, sense 4. :bit: n. [from the mainstream meaning and "Binary digIT"] 1. [techspeak] The unit of information; the amount of information obtained from knowing the answer to a yes-or-no question for which the two outcomes are equally probable. 2. [techspeak] A computational quantity that can take on one of two values, such as true and false or 0 and 1. 3. A mental flag: a reminder that something should be done eventually. "I have a bit set for you." (I haven't seen you for a while, and I'm supposed to tell or ask you something.) 4. More generally, a (possibly incorrect) mental state of belief. "I have a bit set that says that you were the last guy to hack on EMACS." (Meaning "I think you were the last guy to hack on EMACS, and what I am about to say is predicated on this, so please stop me if this isn't true.") "I just need one bit from you" is a polite way of indicating that you intend only a short interruption for a question that can presumably be answered yes or no. A bit is said to be set if its value is true or 1, and reset or clear if its value is false or 0. One speaks of setting and clearing bits. To {toggle} or invert a bit is to change it, either from 0 to 1 or from 1 to 0. See also {flag}, {trit}, {mode bit}. The term bit first appeared in print in the computer-science sense in a 1948 paper by information theorist Claude Shannon, and was there credited to the early computer scientist John Tukey (who also seems to have coined the term software). Tukey records that bit evolved over a lunch table as a handier alternative to bigit or binit, at a conference in the winter of 1943-44. :bit bashing: n. (alt.: bit diddling or {bit twiddling}) Term used to describe any of several kinds of low-level programming characterized by manipulation of {bit}, {flag}, {nybble}, and other smaller-than-character-sized pieces of data; these include low-level device control, encryption algorithms, checksum and error-correcting codes, hash functions, some flavors of graphics programming (see {bitblt}), and assembler/compiler code generation. May connote either tedium or a real technical challenge (more usually the former). "The command decoding for the new tape driver looks pretty solid but the bit-bashing for the control registers still has bugs." See also {mode bit}. :bit bucket: n. [very common] 1. The universal data sink (originally, the mythical receptacle used to catch bits when they fall off the end of a register during a shift instruction). Discarded, lost, or destroyed data is said to have gone to the bit bucket. On {Unix}, often used for {/dev/null}. Sometimes amplified as the Great Bit Bucket in the Sky. 2. The place where all lost mail and news messages eventually go. The selection is performed according to {Finagle's Law}; important mail is much more likely to end up in the bit bucket than junk mail, which has an almost 100% probability of getting delivered. Routing to the bit bucket is automatically performed by mail-transfer agents, news systems, and the lower layers of the network. 3. The ideal location for all unwanted mail responses: "Flames about this article to the bit bucket." Such a request is guaranteed to overflow one's mailbox with flames. 4. Excuse for all mail that has not been sent. "I mailed you those figures last week; they must have landed in the bit bucket." Compare {black hole}. This term is used purely in jest. It is based on the fanciful notion that bits are objects that are not destroyed but only misplaced. This appears to have been a mutation of an earlier term `bit box', about which the same legend was current; old-time hackers also report that trainees used to be told that when the CPU stored bits into memory it was actually pulling them "out of the bit box". See also {chad box}. Another variant of this legend has it that, as a consequence of the "parity preservation law", the number of 1 bits that go to the bit bucket must equal the number of 0 bits. Any imbalance results in bits filling up the bit bucket. A qualified computer technician can empty a full bit bucket as part of scheduled maintenance. The source for all these meanings, is, historically, the fact that the {chad box} on a paper-tape punch was sometimes called a bit bucket. [75-10-04.png] A literal {bit bucket}. (The next cartoon in the Crunchly saga is 76-02-14) :bit decay: n. See {bit rot}. People with a physics background tend to prefer this variant for the analogy with particle decay. See also {computron}, {quantum bogodynamics}. :bit rot: n. [common] Also {bit decay}. Hypothetical disease the existence of which has been deduced from the observation that unused programs or features will often stop working after sufficient time has passed, even if `nothing has changed'. The theory explains that bits decay as if they were radioactive. As time passes, the contents of a file or the code in a program will become increasingly garbled. There actually are physical processes that produce such effects (alpha particles generated by trace radionuclides in ceramic chip packages, for example, can change the contents of a computer memory unpredictably, and various kinds of subtle media failures can corrupt files in mass storage), but they are quite rare (and computers are built with error-detecting circuitry to compensate for them). The notion long favored among hackers that cosmic rays are among the causes of such events turns out to be a myth; see the {cosmic rays} entry for details. The term {software rot} is almost synonymous. Software rot is the effect, bit rot the notional cause. :bit twiddling: n. [very common] 1. (pejorative) An exercise in tuning (see {tune}) in which incredible amounts of time and effort go to produce little noticeable improvement, often with the result that the code becomes incomprehensible. 2. Aimless small modification to a program, esp. for some pointless goal. 3. Approx. syn. for {bit bashing}; esp. used for the act of frobbing the device control register of a peripheral in an attempt to get it back to a known state. :bit-paired keyboard: n.,obs. (alt.: bit-shift keyboard) A non-standard keyboard layout that seems to have originated with the Teletype ASR-33 and remained common for several years on early computer equipment. The ASR-33 was a mechanical device (see {EOU}), so the only way to generate the character codes from keystrokes was by some physical linkage. The design of the ASR-33 assigned each character key a basic pattern that could be modified by flipping bits if the SHIFT or the CTRL key was pressed. In order to avoid making the thing even more of a kluge than it already was, the design had to group characters that shared the same basic bit pattern on one key. Looking at the ASCII chart, we find: high low bits bits 0000 0001 0010 0011 0100 0101 0110 0111 1000 1001 010 ! " # $ % & ' ( ) 011 0 1 2 3 4 5 6 7 8 9 This is why the characters !"#$%&'() appear where they do on a Teletype (thankfully, they didn't use shift-0 for space). The Teletype Model 33 was actually designed before ASCII existed, and was originally intended to use a code that contained these two rows: low bits high 0000 0010 0100 0110 1000 1010 1100 1110 bits 0001 0011 0101 0111 1001 1011 1101 1111 10 ) ! bel # $ % wru & * ( " : ? _ , . 11 0 1 2 3 4 5 6 7 8 9 ' ; / - esc del The result would have been something closer to a normal keyboard. But as it happened, Teletype had to use a lot of persuasion just to keep ASCII, and the Model 33 keyboard, from looking like this instead: ! " ? $ ' & - ( ) ; : * / , . 0 1 2 3 4 5 6 7 8 9 + ~ < > × | Teletype's was not the weirdest variant of the {QWERTY} layout widely seen, by the way; that prize should probably go to one of several (differing) arrangements on IBM's even clunkier 026 and 029 card punches. When electronic terminals became popular, in the early 1970s, there was no agreement in the industry over how the keyboards should be laid out. Some vendors opted to emulate the Teletype keyboard, while others used the flexibility of electronic circuitry to make their product look like an office typewriter. Either choice was supported by the ANSI computer keyboard standard, X4.14-1971, which referred to the alternatives as "logical bit pairing" and "typewriter pairing". These alternatives became known as bit-paired and typewriter-paired keyboards. To a hacker, the bit-paired keyboard seemed far more logical -- and because most hackers in those days had never learned to touch-type, there was little pressure from the pioneering users to adapt keyboards to the typewriter standard. The doom of the bit-paired keyboard was the large-scale introduction of the computer terminal into the normal office environment, where out-and-out technophobes were expected to use the equipment. The typewriter-paired standard became universal, X4.14 was superseded by X4.23-1982, bit-paired hardware was quickly junked or relegated to dusty corners, and both terms passed into disuse. However, in countries without a long history of touch typing, the argument against the bit-paired keyboard layout was weak or nonexistent. As a result, the standard Japanese keyboard, used on PCs, Unix boxen etc. still has all of the !"#$%&'() characters above the numbers in the ASR-33 layout. :bitblt: /bit´blit/, n. [from {BLT}, q.v.:] 1. [common] Any of a family of closely related algorithms for moving and copying rectangles of bits between main and display memory on a bit-mapped device, or between two areas of either main or display memory (the requirement to do the {Right Thing} in the case of overlapping source and destination rectangles is what makes BitBlt tricky). 2. Synonym for {blit} or {BLT}. Both uses are borderline techspeak. :bits: pl.n. 1. Information. Examples: "I need some bits about file formats." ("I need to know about file formats.") Compare {core dump}, sense 4. 2. Machine-readable representation of a document, specifically as contrasted with paper: "I have only a photocopy of the Jargon File; does anyone know where I can get the bits?". See {softcopy}, {source of all good bits} See also {bit}. :bitty box: /bit´ee boks/, n. 1. A computer sufficiently small, primitive, or incapable as to cause a hacker acute claustrophobia at the thought of developing software on or for it. Especially used of small, obsolescent, single-tasking-only personal machines such as the Atari 800, Osborne, Sinclair, VIC-20, TRS-80, or IBM PC. 2. [Pejorative] More generally, the opposite of `real computer' (see {Get a real computer!}). See also {mess-dos}, {toaster}, and {toy}. :bixie: /bik´see/, n. Variant {emoticon}s used BIX (the BIX Information eXchange); the term survived the demise of BIX itself. The most common ({smiley}) bixie is <@_@>, representing two cartoon eyes and a mouth. These were originally invented in an SF fanzine called APA-L and imported to BIX by one of the earliest users. :black art: n. [common] A collection of arcane, unpublished, and (by implication) mostly ad-hoc techniques developed for a particular application or systems area (compare {black magic}). VLSI design and compiler code optimization were (in their beginnings) considered classic examples of black art; as theory developed they became {deep magic}, and once standard textbooks had been written, became merely {heavy wizardry}. The huge proliferation of formal and informal channels for spreading around new computer-related technologies during the last twenty years has made both the term black art and what it describes less common than formerly. See also {voodoo programming}. :black hat: 1. [common among security specialists] A {cracker}, someone bent on breaking into the system you are protecting. Oppose the less comon white hat for an ally or friendly security specialist; the term gray hat is in occasional use for people with cracker skills operating within the law, e.g. in doing security evaluations. All three terms derive from the dress code of formulaic Westerns, in which bad guys wore black hats and good guys white ones. 2. [spamfighters] `Black hat', `white hat', and `gray hat' are also used to denote the spam-friendliness of ISPs: a black hat ISP harbors spammers and doesn't terminate them; a white hat ISP terminates upon the first LART; and gray hat ISPs terminate only reluctantly and/or slowly. This has led to the concept of a hat check: someone considering a potential business relationship with an ISP or other provider will post a query to a {NANA} group, asking about the provider's hat color. The term albedo has also been used to describe a provider's spam-friendliness. :black hole: n.,vt. [common] What data (a piece of email or netnews, or a stream of TCP/IP packets) has fallen into if it disappears mysteriously between its origin and destination sites (that is, without returning a {bounce message}). "I think there's a black hole at foovax!" conveys suspicion that site foovax has been dropping a lot of stuff on the floor lately (see {drop on the floor}). The implied metaphor of email as interstellar travel is interesting in itself. Readily verbed as blackhole: "That router is blackholing IDP packets." Compare {bit bucket} and see {RBL}. :black magic: n. [common] A technique that works, though nobody really understands why. More obscure than {voodoo programming}, which may be done by cookbook. Compare also {black art}, {deep magic}, and {magic number} (sense 2). :Black Screen of Death: [prob.: related to the Floating Head of Death in a famous Far Side cartoon.] A failure mode of {Microsloth Windows}. On an attempt to launch a DOS box, a networked Windows system not uncommonly blanks the screen and locks up the PC so hard that it requires a cold {boot} to recover. This unhappy phenomenon is known as The Black Screen of Death. See also {Blue Screen of Death}, which has become rather more common. :blammo: v. [Oxford Brookes University and alumni, UK] To forcibly remove someone from any interactive system, especially talker systems. The operators, who may remain hidden, may "blammo" a user who is misbehaving. Very similar to archaic MIT gun; in fact, the blammo-gun is a notional device used to "blammo" someone. While in actual fact the only incarnation of the blammo-gun is the command used to forcibly eject a user, operators speak of different levels of blammo-gun fire; e.g., a blammo-gun to `stun' will temporarily remove someone, but a blammo-gun set to `maim' will stop someone coming back on for a while. :blargh: /blarg/, n. [MIT; now common] The opposite of {ping}, sense 5; an exclamation indicating that one has absorbed or is emitting a quantum of unhappiness. Less common than {ping}. :blast: 1. v.,n. Synonym for {BLT}, used esp. for large data sends over a network or comm line. Opposite of {snarf}. Usage: uncommon. The variant `blat' has been reported. 2. vt. [HP/Apollo] Synonymous with {nuke} (sense 3). Sometimes the message Unable to kill all processes. Blast them (y/n)? would appear in the command window upon logout. :blat: n. 1. Syn. {blast}, sense 1. 2. See {thud}. :bletch: /blech/, interj. [very common; from Yiddish/German `brechen', to vomit, poss. via comic-strip exclamation `blech'] Term of disgust. Often used in "Ugh, bletch". Compare {barf}. :bletcherous: /blech'@·r@s/, adj. Disgusting in design or function; esthetically unappealing. This word is seldom used of people. "This keyboard is bletcherous!" (Perhaps the keys don't work very well, or are misplaced.) See {losing}, {cretinous}, {bagbiting}, {bogus}, and {random}. The term {bletcherous} applies to the esthetics of the thing so described; similarly for {cretinous}. By contrast, something that is losing or bagbiting may be failing to meet objective criteria. See also {bogus} and {random}, which have richer and wider shades of meaning than any of the above. :blinkenlights: /blink'@n·li:tz/, n. [common] Front-panel diagnostic lights on a computer, esp. a {dinosaur}. Now that dinosaurs are rare, this term usually refers to status lights on a modem, network hub, or the like. This term derives from the last word of the famous blackletter-Gothic sign in mangled pseudo-German that once graced about half the computer rooms in the English-speaking world. One version ran in its entirety as follows: ACHTUNG! ALLES LOOKENSPEEPERS! Alles touristen und non-technischen looken peepers! Das computermachine ist nicht fuer gefingerpoken und mittengrabben. Ist easy schnappen der springenwerk, blowenfusen und poppencorken mit spitzensparken. Ist nicht fuer gewerken bei das dumpkopfen. Das rubbernecken sichtseeren keepen das cotten-pickenen hans in das pockets muss; relaxen und watchen das blinkenlichten. This silliness dates back at least as far as 1955 at IBM and had already gone international by the early 1960s, when it was reported at London University's ATLAS computing site. There are several variants of it in circulation, some of which actually do end with the word `blinkenlights'. In an amusing example of turnabout-is-fair-play, German hackers have developed their own versions of the blinkenlights poster in fractured English, one of which is reproduced here: ATTENTION This room is fullfilled mit special electronische equippment. Fingergrabbing and pressing the cnoeppkes from the computers is allowed for die experts only! So all the "lefthanders" stay away and do not disturben the brainstorming von here working intelligencies. Otherwise you will be out thrown and kicked anderswhere! Also: please keep still and only watchen astaunished the blinkenlights. See also {geef}. Old-time hackers sometimes get nostalgic for blinkenlights because they were so much more fun to look at than a blank panel. Sadly, very few computers still have them (the three LEDs on a PC keyboard certainly don't count). The obvious reasons (cost of wiring, cost of front-panel cutouts, almost nobody needs or wants to interpret machine-register states on the fly anymore) are only part of the story. Another part of it is that radio-frequency leakage from the lamp wiring was beginning to be a problem as far back as transistor machines. But the most fundamental fact is that there are very few signals slow enough to blink an LED these days! With slow CPUs, you could watch the bus register or instruction counter tick, but at 33/66/150MHz it's all a blur. Despite this, a couple of relatively recent computer designs of note have featured programmable blinkenlights that were added just because they looked cool. The Connection Machine, a 65,536-processor parallel computer designed in the mid-1980s, was a black cube with one side covered with a grid of red blinkenlights; the sales demo had them evolving {life} patterns. A few years later the ill-fated BeBox (a personal computer designed to run the BeOS operating system) featured twin rows of blinkenlights on the case front. When Be, Inc. decided to get out of the hardware business in 1996 and instead ported their OS to the PowerPC and later to the Intel architecture, many users suffered severely from the absence of their beloved blinkenlights. Before long an external version of the blinkenlights driven by a PC serial port became available; there is some sort of plot symmetry in the fact that it was assembled by a German. Finally, a version updated for the Internet has been seen on news.admin.net-abuse.email: ACHTUNG! ALLES LOOKENSPEEPERS! Das Internet is nicht fuer gefingerclicken und giffengrabben. Ist eas y droppenpacket der routers und overloaden der backbone mit der spammen und der me-tooen. Ist nicht fuer gewerken bei das dumpkopfen. Das mausklicken sichtseeren keepen das bandwit-spewin hans in das pockets muss; relaxen und watchen das cursorblinken. This newest version partly reflects reports that the word `blinkenlights' is (in 1999) undergoing something of a revival in usage, but applied to networking equipment. The transmit and receive lights on routers, activity lights on switches and hubs, and other network equipment often blink in visually pleasing and seemingly coordinated ways. Although this is different in some ways from register readings, a tall stack of Cisco equipment or a 19-inch rack of ISDN terminals can provoke a similar feeling of hypnotic awe, especially in a darkened network operations center or server room. The ancestor of the original blinkenlights posters of the 1950s was probably this: [gefingerpoken.jpg] We are informed that cod-German parodies of this kind were very common in Allied machine shops during and following WWII. Germans, then as now, had a reputation for being both good with precision machinery and prone to officious notices. :blit: /blit/, vt. 1. [common] To copy a large array of bits from one part of a computer's memory to another part, particularly when the memory is being used to determine what is shown on a display screen. "The storage allocator picks through the table and copies the good parts up into high memory, and then blits it all back down again." See {bitblt}, {BLT}, {dd}, {cat}, {blast}, {snarf}. More generally, to perform some operation (such as toggling) on a large array of bits while moving them. 2. [historical, rare] Sometimes all-capitalized as BLIT: an early experimental bit-mapped terminal designed by Rob Pike at Bell Labs, later commercialized as the AT&T 5620. (The folk etymology from "Bell Labs Intelligent Terminal" is incorrect. Its creators liked to claim that "Blit" stood for the Bacon, Lettuce, and Interactive Tomato.) :blitter: /blit´r/, n. [common] A special-purpose chip or hardware system built to perform {blit} operations, esp. used for fast implementation of bit-mapped graphics. The Commodore Amiga and a few other micros have these, but since 1990 the trend has been away from them (however, see {cycle of reincarnation}). Syn. {raster blaster}. :blivet: /bliv'@t/, n. [allegedly from a World War II military term meaning "ten pounds of manure in a five-pound bag"] 1. An intractable problem. 2. A crucial piece of hardware that can't be fixed or replaced if it breaks. 3. A tool that has been hacked over by so many incompetent programmers that it has become an unmaintainable tissue of hacks. 4. An out-of-control but unkillable development effort. 5. An embarrassing bug that pops up during a customer demo. 6. In the subjargon of computer security specialists, a denial-of-service attack performed by hogging limited resources that have no access controls (for example, shared spool space on a multi-user system). This term has other meanings in other technical cultures; among experimental physicists and hardware engineers of various kinds it seems to mean any random object of unknown purpose (similar to hackish use of {frob}). It has also been used to describe an amusing trick-the-eye drawing resembling a three-pronged fork that appears to depict a three-dimensional object until one realizes that the parts fit together in an impossible way. [blivet.png] This is a blivet :bloatware: n. [common] Software that provides minimal functionality while requiring a disproportionate amount of diskspace and memory. Especially used for application and OS upgrades. This term is very common in the Windows/NT world. So is its cause. :BLOB: 1. n. [acronym: Binary Large OBject] Used by database people to refer to any random large block of bits that needs to be stored in a database, such as a picture or sound file. The essential point about a BLOB is that it's an object that cannot be interpreted within the database itself. 2. v. To {mailbomb} someone by sending a BLOB to him/her; esp. used as a mild threat. "If that program crashes again, I'm going to BLOB the core dump to you." :block: v. [common; from process scheduling terminology in OS theory] 1. vi. To delay or sit idle while waiting for something. "We're blocking until everyone gets here." Compare {busy-wait}. 2. block on vt. To block, waiting for (something). "Lunch is blocked on Phil's arrival." :blog: n. [common] Short for weblog, an on-line web-zine or diary (usually with facilities for reader comments and discussion threads) made accessible through the World Wide Web. This term is widespread and readily forms derivatives, of which the best known may be {blogosphere}. :Bloggs Family: n. An imaginary family consisting of Fred and Mary Bloggs and their children. Used as a standard example in knowledge representation to show the difference between extensional and intensional objects. For example, every occurrence of "Fred Bloggs" is the same unique person, whereas occurrences of "person" may refer to different people. Members of the Bloggs family have been known to pop up in bizarre places such as the old {DEC} Telephone Directory. Compare {Dr. Fred Mbogo}; {J. Random Hacker}; {Fred Foobar}. :blogosphere: The totality of all {blog}s. A culture heavily overlapping with but not coincident with hackerdom; a few of its key coinages ({blogrolling}, {fisking}, {anti-idiotarianism}) are recorded in this lexicon for flavor. Bloggers often divide themselves into warbloggers and techbloggers. The techbloggers write about technology and technology policy, while the warbloggers are more politically focused and tend to be preoccupied with U.S. and world response to the post-9/11 war against terrorism. The overlap with hackerdom is heaviest among the techbloggers, but several of the most prominent warbloggers are also hackers. Bloggers in general tend to be aware of and sympathetic to the hacker culture. :blogrolling: [From the American political term `logrolling', for supporting another's pet bill in the legislature in exchange for reciprocal support,] When you hotlink to other bloggers' blogs (and-or other bloggers' specific blog entries) in your blog, you are blogrolling. This is frequently reciprocal. :blow an EPROM: /bloh @n ee´prom/, v. (alt.: blast an EPROM, burn an EPROM) To program a read-only memory, e.g.: for use with an embedded system. This term arose because the programming process for the Programmable Read-Only Memories (PROMs) that preceded present-day Erasable Programmable Read-Only Memories (EPROMs) involved intentionally blowing tiny electrical fuses on the chip. The usage lives on (it's too vivid and expressive to discard) even though the write process on EPROMs is nondestructive. :blow away: vt. To remove (files and directories) from permanent storage, generally by accident. "He reformatted the wrong partition and blew away last night's netnews." Oppose {nuke}. :blow out: vi. [prob.: from mining and tunneling jargon] Of software, to fail spectacularly; almost as serious as {crash and burn}. See {blow past}, {blow up}, {die horribly}. :blow past: vt. To {blow out} despite a safeguard. "The server blew past the 5K reserve buffer." :blow up: vi. 1. [scientific computation] To become unstable. Suggests that the computation is diverging so rapidly that it will soon overflow or at least go {nonlinear}. 2. Syn. {blow out}. :BLT: /B·L·T/, /bl@t/, /belt/, n.,vt. Synonym for {blit}. This is the original form of {blit} and the ancestor of {bitblt}. It referred to any large bit-field copy or move operation (one resource-intensive memory-shuffling operation done on pre-paged versions of ITS, WAITS, and TOPS-10 was sardonically referred to as "The Big BLT"). The jargon usage has outlasted the {PDP-10} BLock Transfer instruction from which {BLT} derives; nowadays, the assembler mnemonic {BLT} almost always means "Branch if Less Than zero". :blue box: n. 1. obs. Once upon a time, before all-digital switches made it possible for the phone companies to move them out of band, one could actually hear the switching tones used to route long-distance calls. Early {phreaker}s built devices called blue boxes that could reproduce these tones, which could be used to commandeer portions of the phone network. (This was not as hard as it may sound; one early phreak acquired the sobriquet "Captain Crunch" after he proved that he could generate switching tones with a plastic whistle pulled out of a box of Captain Crunch cereal!) There were other colors of box with more specialized phreaking uses; red boxes, black boxes, silver boxes, etc. There were boxes of other colors as well, but the blue box was the original and archetype. 2. n. An {IBM} machine, especially a large (non-PC) one. :Blue Glue: n. [IBM; obs.] IBM's SNA (Systems Network Architecture), an incredibly {losing} and {bletcherous} communications protocol once widely favored at commercial shops that didn't know any better (like other proprietary networking protocols, it became obsolete and effectively disappeared after the Internet explosion c.1994). The official IBM definition is "that which binds blue boxes together." See {fear and loathing}. It may not be irrelevant that Blue Glue is the trade name of a 3M product that is commonly used to hold down the carpet squares to the removable panel floors common in {dinosaur pen}s. A correspondent at U. Minn. reports that the CS department there has about 80 bottles of the stuff hanging about, so they often refer to any messy work to be done as using the blue glue. :blue goo: n. Term for `police' {nanobot}s intended to prevent {gray goo}, denature hazardous waste, destroy pollution, put ozone back into the stratosphere, prevent halitosis, and promote truth, justice, and the American way, etc. The term "Blue Goo" can be found in Dr. Seuss's Fox In Socks to refer to a substance much like bubblegum. `Would you like to chew blue goo, sir?'. See {nanotechnology}. :Blue Screen of Death: n. [common] This term is closely related to the older {Black Screen of Death} but much more common (many non-hackers have picked it up). Due to the extreme fragility and bugginess of Microsoft Windows, misbehaving applications can readily crash the OS (and the OS sometimes crashes itself spontaneously). The Blue Screen of Death, sometimes decorated with hex error codes, is what you get when this happens. (Commonly abbreviated {BSOD}.) The following entry from the Salon Haiku Contest, seems to have predated popular use of the term: Windows NT crashed. I am the Blue Screen of Death No one hears your screams. :blue wire: n. [IBM] Patch wires (esp. 30 AWG gauge) added to circuit boards at the factory to correct design or fabrication problems. Blue wire is not necessarily blue, the term describes function rather than color. These may be necessary if there hasn't been time to design and qualify another board version. In Great Britain this can be bodge wire, after mainstream slang bodge for a clumsy improvisation or sloppy job of work. Compare {purple wire}, {red wire}, {yellow wire}, {pink wire}. :blurgle: /bler´gl/, n. [UK] Spoken {metasyntactic variable}, to indicate some text that is obvious from context, or which is already known. If several words are to be replaced, blurgle may well be doubled or tripled. "To look for something in several files use `grep string blurgle blurgle'." In each case, "blurgle blurgle" would be understood to be replaced by the file you wished to search. Compare {mumble}, sense 7. :BNF: /B·N·F/, n. 1. [techspeak] Acronym for Backus Normal Form (later retronymed to Backus-Naur Form because BNF was not in fact a normal form), a metasyntactic notation used to specify the syntax of programming languages, command sets, and the like. Widely used for language descriptions but seldom documented anywhere, so that it must usually be learned by osmosis from other hackers. Consider this BNF for a U.S. postal address: ::= ::= | "." ::= [] | ::= [] ::= "," This translates into English as: "A postal-address consists of a name-part, followed by a street-address part, followed by a zip-code part. A personal-part consists of either a first name or an initial followed by a dot. A name-part consists of either: a personal-part followed by a last name followed by an optional jr-part (Jr., Sr., or dynastic number) and end-of-line, or a personal part followed by a name part (this rule illustrates the use of recursion in BNFs, covering the case of people who use multiple first and middle names and/or initials). A street address consists of an optional apartment specifier, followed by a street number, followed by a street name. A zip-part consists of a town-name, followed by a comma, followed by a state code, followed by a ZIP-code followed by an end-of-line." Note that many things (such as the format of a personal-part, apartment specifier, or ZIP-code) are left unspecified. These are presumed to be obvious from context or detailed somewhere nearby. See also {parse}. 2. Any of a number of variants and extensions of BNF proper, possibly containing some or all of the {regexp} wildcards such as * or +. In fact the example above isn't the pure form invented for the Algol-60 report; it uses [], which was introduced a few years later in IBM's PL/I definition but is now universally recognized. 3. In {science-fiction fandom}, a `Big-Name Fan' (someone famous or notorious). Years ago a fan started handing out black-on-green BNF buttons at SF conventions; this confused the hacker contingent terribly. :boa: n. Any one of the fat cables that lurk under the floor in a {dinosaur pen}. Possibly so called because they display a ferocious life of their own when you try to lay them straight and flat after they have been coiled for some time. It is rumored within IBM that channel cables for the 370 are limited to 200 feet because beyond that length the boas get dangerous -- and it is worth noting that one of the major cable makers uses the trademark `Anaconda'. :board: n. 1. In-context synonym for {bboard}; sometimes used even for Usenet newsgroups (but see usage note under {bboard}, sense 1). 2. An electronic circuit board. :boat anchor: n. [common; from ham radio] 1. Like {doorstop} but more severe; implies that the offending hardware is irreversibly dead or useless. "That was a working motherboard once. One lightning strike later, instant boat anchor!" 2. A person who just takes up space. 3. Obsolete but still working hardware, especially when used of an old, bulky, quirky system; originally a term of annoyance, but became more and more affectionate as the hardware became more and more obsolete. Auctioneers use this term for a large, undesirable object such as a washing machine; actual boating enthusiasts, however, use "mooring anchor" for frustrating (not actually useless) equipment. :bob: n. At Demon Internet, all tech support personnel are called "Bob". (Female support personnel have an option on "Bobette"). This has nothing to do with Bob the divine drilling-equipment salesman of the {Church of the SubGenius}. Nor is it acronymized from "Brother Of {BOFH}", though all parties agree it could have been. Rather, it was triggered by an unusually large draft of new tech-support people in 1995. It was observed that there would be much duplication of names. To ease the confusion, it was decided that all support techs would henceforth be known as "Bob", and identity badges were created labelled "Bob 1" and "Bob 2". ("No, we never got any further" reports a witness). The reason for "Bob" rather than anything else is due to a {luser} calling and asking to speak to "Bob", despite the fact that no "Bob" was currently working for Tech Support. Since we all know "the customer is always right", it was decided that there had to be at least one "Bob" on duty at all times, just in case. This sillyness snowballed inexorably. Shift leaders and managers began to refer to their groups of "bobs". Whole ranks of support machines were set up (and still exist in the DNS as of 1999) as bob1 through bobN. Then came alt.tech-support.recovery, and it was filled with Demon support personnel. They all referred to themselves, and to others, as "bob", and after a while it caught on. There is now a Bob Code describing the Bob nature. :bodge: [Commonwealth hackish] Syn. {kludge} or {hack} (sense 1). "I'll bodge this in now and fix it later". :BOF: /B·O·F/, /bof/, n. 1. [common] Abbreviation for the phrase "Birds Of a Feather" (flocking together), an informal discussion group and/or bull session scheduled on a conference program. It is not clear where or when this term originated, but it is now associated with the USENIX conferences for Unix techies and was already established there by 1984. It was used earlier than that at DECUS conferences and is reported to have been common at SHARE meetings as far back as the early 1960s. 2. Acronym, "Beginning of File". :BOFH: //, n. [common] Acronym, Bastard Operator From Hell. A system administrator with absolutely no tolerance for {luser}s. "You say you need more filespace? Seems to me you have plenty left..." Many BOFHs (and others who would be BOFHs if they could get away with it) hang out in the newsgroup alt.sysadmin.recovery, although there has also been created a top-level newsgroup hierarchy (bofh.*) of their own. Several people have written stories about BOFHs. The set usually considered canonical is by Simon Travaglia and may be found at the Bastard Home Page. BOFHs and BOFH wannabes hang out on {scary devil monastery} and wield {LART}s. :bogo-sort: /boh`goh·sort´/, n. (var.: stupid-sort) The archetypical perversely awful algorithm (as opposed to {bubble sort}, which is merely the generic bad algorithm). Bogo-sort is equivalent to repeatedly throwing a deck of cards in the air, picking them up at random, and then testing whether they are in order. It serves as a sort of canonical example of awfulness. Looking at a program and seeing a dumb algorithm, one might say "Oh, I see, this program uses bogo-sort." Esp. appropriate for algorithms with factorial or super-exponential running time in the average case and probabilistically infinite worst-case running time. Compare {bogus}, {brute force}. A spectacular variant of bogo-sort has been proposed which has the interesting property that, if the Many Worlds interpretation of quantum mechanics is true, it can sort an arbitrarily large array in linear time. (In the Many-Worlds model, the result of any quantum action is to split the universe-before into a sheaf of universes-after, one for each possible way the state vector can collapse; in any one of the universes-after the result appears random.) The steps are: 1. Permute the array randomly using a quantum process, 2. If the array is not sorted, destroy the universe (checking that the list is sorted requires O(n) time). Implementation of step 2 is left as an exercise for the reader. :bogometer: /boh·gom'·@t·er/, n. A notional instrument for measuring {bogosity}. Compare the {Troll-O-Meter} and the `wankometer' described in the {wank} entry; see also {bogus}. :BogoMIPS: /bo´go·mips/, n. The number of million times a second a processor can do absolutely nothing. The {Linux} OS measures BogoMIPS at startup in order to calibrate some soft timing loops that will be used later on; details at the BogoMIPS mini-HOWTO. The name Linus chose, of course, is an ironic comment on the uselessness of all other {MIPS} figures. :bogon: /boh´gon/, n. [very common; by analogy with proton/electron/neutron, but doubtless reinforced after 1980 by the similarity to Douglas Adams's `Vogons'; see the Bibliography in Appendix C and note that Arthur Dent actually mispronounces `Vogons' as `Bogons' at one point] 1. The elementary particle of bogosity (see {quantum bogodynamics}). For instance, "the Ethernet is emitting bogons again" means that it is broken or acting in an erratic or bogus fashion. 2. A query packet sent from a TCP/IP domain resolver to a root server, having the reply bit set instead of the query bit. 3. Any bogus or incorrectly formed packet sent on a network. 4. By synecdoche, used to refer to any bogus thing, as in "I'd like to go to lunch with you but I've got to go to the weekly staff bogon". 5. A person who is bogus or who says bogus things. This was historically the original usage, but has been overtaken by its derivative senses 1--4. See also {bogosity}, {bogus}; compare {psyton}, {fat electrons}, {magic smoke}. The bogon has become the type case for a whole bestiary of nonce particle names, including the `clutron' or `cluon' (indivisible particle of cluefulness, obviously the antiparticle of the bogon) and the futon (elementary particle of {randomness}, or sometimes of lameness). These are not so much live usages in themselves as examples of a live meta-usage: that is, it has become a standard joke or linguistic maneuver to "explain" otherwise mysterious circumstances by inventing nonce particle names. And these imply nonce particle theories, with all their dignity or lack thereof (we might note parenthetically that this is a generalization from "(bogus particle) theories" to "bogus (particle theories)"!). Perhaps such particles are the modern-day equivalents of trolls and wood-nymphs as standard starting-points around which to construct explanatory myths. Of course, playing on an existing word (as in the `futon') yields additional flavor. Compare {magic smoke}. :bogon filter: /boh´gon fil'tr/, n. Any device, software or hardware, that limits or suppresses the flow and/or emission of bogons. "Engineering hacked a bogon filter between the Cray and the VAXen, and now we're getting fewer dropped packets." See also {bogosity}, {bogus}. :bogon flux: /boh´gon fluhks/, n. A measure of a supposed field of {bogosity} emitted by a speaker, measured by a {bogometer}; as a speaker starts to wander into increasing bogosity a listener might say "Warning, warning, bogon flux is rising". See {quantum bogodynamics}. :bogosity: /boh·go´s@·tee/, n. 1. [orig. CMU, now very common] The degree to which something is {bogus}. Bogosity is measured with a {bogometer}; in a seminar, when a speaker says something bogus, a listener might raise his hand and say "My bogometer just triggered". More extremely, "You just pinned my bogometer" means you just said or did something so outrageously bogus that it is off the scale, pinning the bogometer needle at the highest possible reading (one might also say "You just redlined my bogometer"). The agreed-upon unit of bogosity is the {microLenat}. 2. The potential field generated by a {bogon flux}; see {quantum bogodynamics}. See also {bogon flux}, {bogon filter}, {bogus}. :bogotify: /boh·go´t@·fi:/, vt. To make or become bogus. A program that has been changed so many times as to become completely disorganized has become bogotified. If you tighten a nut too hard and strip the threads on the bolt, the bolt has become bogotified and you had better not use it any more. This coinage led to the notional autobogotiphobia defined as `the fear of becoming bogotified'; but is not clear that the latter has ever been `live' jargon rather than a self-conscious joke in jargon about jargon. See also {bogosity}, {bogus}. :bogue out: /bohg owt/, vi. To become bogus, suddenly and unexpectedly. "His talk was relatively sane until somebody asked him a trick question; then he bogued out and did nothing but {flame} afterwards." See also {bogosity}, {bogus}. :bogus: adj. 1. Non-functional. "Your patches are bogus." 2. Useless. "OPCON is a bogus program." 3. False. "Your arguments are bogus." 4. Incorrect. "That algorithm is bogus." 5. Unbelievable. "You claim to have solved the halting problem for Turing Machines? That's totally bogus." 6. Silly. "Stop writing those bogus sagas." Astrology is bogus. So is a bolt that is obviously about to break. So is someone who makes blatantly false claims to have solved a scientific problem. (This word seems to have some, but not all, of the connotations of {random} -- mostly the negative ones.) It is claimed that bogus was originally used in the hackish sense at Princeton in the late 1960s. It was spread to CMU and Yale by Michael Shamos, a migratory Princeton alumnus. A glossary of bogus words was compiled at Yale when the word was first popularized there about 1975-76. These coinages spread into hackerdom from CMU and MIT. Most of them remained wordplay objects rather than actual vocabulary items or live metaphors. Examples: amboguous (having multiple bogus interpretations); bogotissimo (in a gloriously bogus manner); bogotophile (one who is pathologically fascinated by the bogus); paleobogology (the study of primeval bogosity). Some bogowords, however, obtained sufficient live currency to be listed elsewhere in this lexicon; see {bogometer}, {bogon}, {bogotify}, and {quantum bogodynamics} and the related but unlisted {Dr. Fred Mbogo}. By the early 1980s `bogus' was also current in something like hacker usage sense in West Coast teen slang, and it had gone mainstream by 1985. A correspondent from Cambridge reports, by contrast, that these uses of bogus grate on British nerves; in Britain the word means, rather specifically, `counterfeit', as in "a bogus 10-pound note". According to Merriam-Webster, the word dates back to 1825 and originally referred to a counterfeiting machine. :Bohr bug: /bohr buhg/, n. [from quantum physics] A repeatable {bug}; one that manifests reliably under a possibly unknown but well-defined set of conditions. Antonym of {heisenbug}; see also {mandelbug}, {schroedinbug}. :boink: /boynk/ 1. [Usenet: variously ascribed to the TV series Cheers, Moonlighting, and Soap]v. To have sex with; compare {bounce}, sense 2. (This is mainstream slang.) In Commonwealth hackish the variant `bonk' is more common. 2. n. After the original Peter Korn `Boinkon' {Usenet} parties, used for almost any net social gathering, e.g., Miniboink, a small boink held by Nancy Gillett in 1988; Minniboink, a Boinkcon in Minnesota in 1989; Humpdayboinks, Wednesday get-togethers held in the San Francisco Bay Area. Compare {@-party}. 3. Var of bonk; see {bonk/oif}. :bomb: 1. v. General synonym for {crash} (sense 1) except that it is not used as a noun; esp. used of software or OS failures. "Don't run Empire with less than 32K stack, it'll bomb." 2. n.,v. Atari ST and Macintosh equivalents of a Unix panic or Amiga {guru meditation}, in which icons of little black-powder bombs or mushroom clouds are displayed, indicating that the system has died. On the Mac, this may be accompanied by a decimal (or occasionally hexadecimal) number indicating what went wrong, similar to the Amiga {guru meditation} number. {MS-DOS} machines tend to get {locked up} in this situation. :bondage-and-discipline language: n. A language (such as {Pascal}, Ada, APL, or Prolog) that, though ostensibly general-purpose, is designed so as to enforce an author's theory of `right programming' even though said theory is demonstrably inadequate for systems hacking or even vanilla general-purpose programming. Often abbreviated `B&D'; thus, one may speak of things "having the B&D nature". See {Pascal}; oppose {languages of choice}. :bonk/oif: /bonk/, /oyf/, interj. In the U.S. {MUD} community, it has become traditional to express pique or censure by bonking the offending person. Convention holds that one should acknowledge a bonk by saying "oif!" and there is a myth to the effect that failing to do so upsets the cosmic bonk/oif balance, causing much trouble in the universe. Some MUDs have implemented special commands for bonking and oifing. Note: in parts of the U.K. `bonk' is a sexually loaded slang term; care is advised in transatlantic conversations (see {boink}). Commonwealth hackers report a similar convention involving the `fish/bang' balance. See also {talk mode}. :book titles: There is a tradition in hackerdom of informally tagging important textbooks and standards documents with the dominant color of their covers or with some other conspicuous feature of the cover. Many of these are described in this lexicon under their own entries. See {Aluminum Book}, {Camel Book}, {Cinderella Book}, {daemon book}, {Dragon Book}, {Orange Book}, {Purple Book}, {Wizard Book}, and {bible}; see also {rainbow series}. Since about 1993 this tradition has gotten a boost from the popular O'Reilly and Associates line of technical books, which usually feature some kind of exotic animal on the cover and are often called by the name of that animal. :boot: v.,n. [techspeak; from `by one's bootstraps'] To load and initialize the operating system on a machine. This usage is no longer jargon (having passed into techspeak) but has given rise to some derivatives that are still jargon. The derivative reboot implies that the machine hasn't been down for long, or that the boot is a {bounce} (sense 4) intended to clear some state of {wedgitude}. This is sometimes used of human thought processes, as in the following exchange: "You've lost me." "OK, reboot. Here's the theory...." This term is also found in the variants cold boot (from power-off condition) and warm boot (with the CPU and all devices already powered up, as after a hardware reset or software crash). Another variant: soft boot, reinitialization of only part of a system, under control of other software still running: "If you're running the {mess-dos} emulator, control-alt-insert will cause a soft-boot of the emulator, while leaving the rest of the system running." Opposed to this there is hard boot, which connotes hostility towards or frustration with the machine being booted: "I'll have to hard-boot this losing Sun." "I recommend booting it hard." One often hard-boots by performing a {power cycle}. Historical note: this term derives from bootstrap loader, a short program that was read in from cards or paper tape, or toggled in from the front panel switches. This program was always very short (great efforts were expended on making it short in order to minimize the labor and chance of error involved in toggling it in), but was just smart enough to read in a slightly more complex program (usually from a card or paper tape reader), to which it handed control; this program in turn was smart enough to read the application or operating system from a magnetic tape drive or disk drive. Thus, in successive steps, the computer `pulled itself up by its bootstraps' to a useful operating state. Nowadays the bootstrap is usually found in ROM or EPROM, and reads the first stage in from a fixed location on the disk, called the `boot block'. When this program gains control, it is powerful enough to load the actual OS and hand control over to it. :Borg: n. In Star Trek: The Next Generation the Borg is a species of cyborg that ruthlessly seeks to incorporate all sentient life into itself; their slogan is "You will be assimilated. Resistance is futile." In hacker parlance, the Borg is usually {Microsoft}, which is thought to be trying just as ruthlessly to assimilate all computers and the entire Internet to itself (there is a widely circulated image of Bill Gates as a Borg). Being forced to use Windows or NT is often referred to as being "Borged". Interestingly, the {Halloween Documents} reveal that this jargon is live within Microsoft itself. See also {Evil Empire}, {Internet Exploiter}. Other companies, notably Intel and UUNet, have also occasionally been equated to the Borg. In IETF circles, where direct pressure from Microsoft is not a daily reality, the Borg is sometimes Cisco. This usage commemorates their tendency to pay any price to hire talent away from their competitors. In fact, at the Spring 1997 IETF, a large number of ex-Cisco employees, all former members of Routing Geeks, showed up with t-shirts printed with "Recovering Borg". :borken: adj. (also borked) Common deliberate typo for `broken'. :bot: n [common on IRC, MUD and among gamers; from "robot"] 1. An {IRC} or {MUD} user who is actually a program. On IRC, typically the robot provides some useful service. Examples are NickServ, which tries to prevent random users from adopting {nick}s already claimed by others, and MsgServ, which allows one to send asynchronous messages to be delivered when the recipient signs on. Also common are `annoybots', such as KissServ, which perform no useful function except to send cute messages to other people. Service bots are less common on MUDs; but some others, such as the `Julia' bot active in 1990--91, have been remarkably impressive Turing-test experiments, able to pass as human for as long as ten or fifteen minutes of conversation. 2. An AI-controlled player in a computer game (especially a first-person shooter such as Quake) which, unlike ordinary monsters, operates like a human-controlled player, with access to a player's weapons and abilities. An example can be found at http://www.telefragged.com/thefatal/. 3. Term used, though less commonly, for a web {spider}. The file for controlling spider behavior on your site is officially the "Robots Exclusion File" and its URL is "http:///robots.txt") Note that bots in all senses were `robots' when the terms first appeared in the early 1990s, but the shortened form is now habitual. :bottom feeder: n. 1. An Internet user that leeches off ISPs -- the sort you can never provide good enough services for, always complains about the price, no matter how low it may be, and will bolt off to another service the moment there is even the slimmest price difference. While most bottom feeders infest free or almost free services such as AOL, MSN, and Hotmail, too many flock to whomever happens to be the cheapest regional ISP at the time. Bottom feeders are often the classic problem user, known for unleashing spam, flamage, and other breaches of {netiquette}. 2. Syn. for {slopsucker}, derived from the fishermen's and naturalists' term for finny creatures who subsist on the primordial ooze. (This sense is older.) :bottom-post: v. In a news or mail reply, to put the response to a news or email message after the quoted content from the parent message. This is correct form, and until around 2000 was so universal on the Internet that neither the term `bottom-post' nor its antonym {top-post} existed. Hackers consider that the best practice is actually to excerpt only the relevent portions of the parent message, then intersperse the poster's response in such a way that each section of response appears directly after the excerpt it applies to. This reduces message bulk, keeps thread content in a logical order, and facilitates reading. :bottom-up implementation: n. Hackish opposite of the techspeak term top-down design. It has been received wisdom in most programming cultures that it is best to design from higher levels of abstraction down to lower, specifying sequences of action in increasing detail until you get to actual code. Hackers often find (especially in exploratory designs that cannot be closely specified in advance) that it works best to build things in the opposite order, by writing and testing a clean set of primitive operations and then knitting them together. Naively applied, this leads to hacked-together bottom-up implementations; a more sophisticated response is middle-out implementation, in which scratch code within primitives at the mid-level of the system is gradually replaced with a more polished version of the lowest level at the same time the structure above the midlevel is being built. :bounce: v. 1. [common; perhaps by analogy to a bouncing check] An electronic mail message that is undeliverable and returns an error notification to the sender is said to bounce. See also {bounce message}. 2. To engage in sexual intercourse; prob.: from the expression `bouncing the mattress', but influenced by Roo's psychosexually loaded "Try bouncing me, Tigger!" from the Winnie-the-Pooh books. Compare {boink}. 3. To casually reboot a system in order to clear up a transient problem (possibly editing a configuration file in the process, if it is one that is only re-read at boot time). Reported primarily among {VMS} and {Unix} users. 4. [VM/CMS programmers] Automatic warm-start of a machine after an error. "I logged on this morning and found it had bounced 7 times during the night" 6. [IBM] To {power cycle} a peripheral in order to reset it. :bounce message: n. [common] Notification message returned to sender by a site unable to relay {email} to the intended Internet address recipient or the next link in a {bang path} (see {bounce}, sense 1). Reasons might include a nonexistent or misspelled username or a {down} relay site. Bounce messages can themselves fail, with occasionally ugly results; see {sorcerer's apprentice mode} and {software laser}. The terms bounce mail and barfmail are also common. :boustrophedon: n. [from a Greek word for turning like an ox while plowing] An ancient method of writing using alternate left-to-right and right-to-left lines. This term is actually philologists' techspeak and typesetters' jargon. Erudite hackers use it for an optimization performed by some computer typesetting software and moving-head printers. The adverbial form `boustrophedonically' is also found (hackers purely love constructions like this). :box: n. A computer; esp. in the construction foo box where foo is some functional qualifier, like graphics, or the name of an OS (thus, Unix box, Windows box, etc.) "We preprocess the data on Unix boxes before handing it up to the mainframe." :boxed comments: n. Comments (explanatory notes attached to program instructions) that occupy several lines by themselves; so called because in assembler and C code they are often surrounded by a box in a style something like this: /************************************************* * * This is a boxed comment in C style * *************************************************/ Common variants of this style omit the asterisks in column 2 or add a matching row of asterisks closing the right side of the box. The sparest variant omits all but the comment delimiters themselves; the `box' is implied. Oppose {winged comments}. :boxen: /bok´sn/, pl.n. [very common; by analogy with {VAXen}] Fanciful plural of {box} often encountered in the phrase `Unix boxen', used to describe commodity {Unix} hardware. The connotation is that any two Unix boxen are interchangeable. :boxology: /bok·sol'@·jee/, n. Syn. {ASCII art}. This term implies a more restricted domain, that of box-and-arrow drawings. "His report has a lot of boxology in it." Compare {macrology}. :bozotic: /boh·zoh´tik/, /boh·zo´tik/, adj. [from the name of a TV clown even more losing than Ronald McDonald] Resembling or having the quality of a bozo; that is, clownish, ludicrously wrong, unintentionally humorous. Compare {wonky}, {demented}. Note that the noun `bozo' occurs in slang, but the mainstream adjectival form would be `bozo-like' or (in New England) `bozoish'. :brain dump: n. [common] The act of telling someone everything one knows about a particular topic or project. Typically used when someone is going to let a new party maintain a piece of code. Conceptually analogous to an operating system {core dump} in that it saves a lot of useful {state} before an exit. "You'll have to give me a brain dump on FOOBAR before you start your new job at HackerCorp." See {core dump} (sense 4). At Sun, this is also known as TOI (transfer of information). :brain fart: n. The actual result of a {braino}, as opposed to the mental glitch that is the braino itself. E.g., typing dir on a Unix box after a session with DOS. :brain-damaged: adj. 1. [common; generalization of "Honeywell Brain Damage" (HBD), a theoretical disease invented to explain certain utter cretinisms in Honeywell {Multics}] adj. Obviously wrong; {cretinous}; {demented}. There is an implication that the person responsible must have suffered brain damage, because he should have known better. Calling something brain-damaged is really bad; it also implies it is unusable, and that its failure to work is due to poor design rather than some accident. "Only six monocase characters per file name? Now that's brain-damaged!" 2. [esp. in the Mac world] May refer to free demonstration software that has been deliberately crippled in some way so as not to compete with the product it is intended to sell. Syn. {crippleware}. :brain-dead: adj. [common] Brain-damaged in the extreme. It tends to imply terminal design failure rather than malfunction or simple stupidity. "This comm program doesn't know how to send a break -- how brain-dead!" :braino: /bray´no/, n. Syn. for {thinko}. See also {brain fart}. :brainwidth: n. [Great Britain] Analagous to {bandwidth} but used strictly for human capacity to process information and especially to multitask. "Writing email is taking up most of my brainwidth right now, I can't look at that Flash animation." :bread crumbs: n. 1. Debugging statements inserted into a program that emit output or log indicators of the program's {state} to a file so you can see where it dies or pin down the cause of surprising behavior. The term is probably a reference to the Hansel and Gretel story from the Brothers Grimm or the older French folktale of Thumbelina; in several variants of these, a character leaves a trail of bread crumbs so as not to get lost in the woods. 2. In user-interface design, any feature that allows some tracking of where you've been, like coloring visited links purple rather than blue in Netscape (also called footprinting). :break: 1. vt. To cause to be {broken} (in any sense). "Your latest patch to the editor broke the paragraph commands." 2. v. (of a program) To stop temporarily, so that it may debugged. The place where it stops is a breakpoint. 3. [techspeak] vi. To send an RS-232 break (two character widths of line high) over a serial comm line. 4. [Unix] vi. To strike whatever key currently causes the tty driver to send SIGINT to the current process. Normally, break (sense 3), delete or {control-C} does this. 5. break break may be said to interrupt a conversation (this is an example of verb doubling). This usage comes from radio communications, which in turn probably came from landline telegraph/teleprinter usage, as badly abused in the Citizen's Band craze of the early 1980s. :break-even point: n. In the process of implementing a new computer language, the point at which the language is sufficiently effective that one can implement the language in itself. That is, for a new language called, hypothetically, FOOGOL, one has reached break-even when one can write a demonstration compiler for FOOGOL in FOOGOL, discard the original implementation language, and thereafter use working versions of FOOGOL to develop newer ones. This is an important milestone; see {MFTL}. Since this entry was first written, several correspondents have reported that there actually was a compiler for a tiny Algol-like language called Foogol floating around on various {VAXen} in the early and mid-1980s. A FOOGOL implementation is available at the Retrocomputing Museum http://www.catb.org/retro/. :breath-of-life packet: n. [XEROX PARC] An Ethernet packet that contains bootstrap (see {boot}) code, periodically sent out from a working computer to infuse the `breath of life' into any computer on the network that has happened to crash. Machines depending on such packets have sufficient hardware or firmware code to wait for (or request) such a packet during the reboot process. See also {dickless workstation}. The notional kiss-of-death packet, with a function complementary to that of a breath-of-life packet, is recommended for dealing with hosts that consume too many network resources. Though `kiss-of-death packet' is usually used in jest, there is at least one documented instance of an Internet subnet with limited address-table slots in a gateway machine in which such packets were routinely used to compete for slots, rather like Christmas shoppers competing for scarce parking spaces. :breedle: n. See {feep}. :Breidbart Index: /bri:d´bart ind@ks/ A measurement of the severity of spam invented by long-time hacker Seth Breidbart, used for programming cancelbots. The Breidbart Index takes into account the fact that excessive multi-posting {EMP} is worse than excessive cross-posting {ECP}. The Breidbart Index is computed as follows: For each article in a spam, take the square-root of the number of newsgroups to which the article is posted. The Breidbart Index is the sum of the square roots of all of the posts in the spam. For example, one article posted to nine newsgroups and again to sixteen would have BI = sqrt(9) + sqrt(16) = 7. It is generally agreed that a spam is cancelable if the Breidbart Index exceeds 20. The Breidbart Index accumulates over a 45-day window. Ten articles yesterday and ten articles today and ten articles tomorrow add up to a 30-article spam. Spam fighters will often reset the count if you can convince them that the spam was accidental and/or you have seen the error of your ways and won't repeat it. Breidbart Index can accumulate over multiple authors. For example, the "Make Money Fast" pyramid scheme exceeded a BI of 20 a long time ago, and is now considered "cancel on sight". :bricktext: [Usenet: common] Text which is carefully composed to be right-justified (and sometimes to have a deliberate gutter at mid-page) without use of extra spaces, just through careful word-length choices. A minor art form. The best examples have something of the quality of imagist poetry. :bring X to its knees: v. [common] To present a machine, operating system, piece of software, or algorithm with a load so extreme or {pathological} that it grinds to a halt.: "To bring a MicroVAX to its knees, try twenty users running {vi} -- or four running {EMACS}." Compare {hog}. :brittle: adj. Said of software that is functional but easily broken by changes in operating environment or configuration, or by any minor tweak to the software itself. Also, any system that responds inappropriately and disastrously to abnormal but expected external stimuli; e.g., a file system that is usually totally scrambled by a power failure is said to be brittle. This term is often used to describe the results of a research effort that were never intended to be robust, but it can be applied to commercial software, which (due to closed-source development) displays the quality far more often than it ought to. Oppose {robust}. :broadcast storm: n. [common] An incorrect packet broadcast on a network that causes most hosts to respond all at once, typically with wrong answers that start the process over again. See {network meltdown}; compare {mail storm}. :broken: adj. 1. Not working according to design (of programs). This is the mainstream sense. 2. Improperly designed, This sense carries a more or less disparaging implication that the designer should have known better, while sense 1 doesn't necessarily assign blame. Which of senses 1 or 2 is intended is conveyed by context and nonverbal cues. 3. Behaving strangely; especially (when used of people) exhibiting extreme depression. :broken arrow: n. [IBM] The error code displayed on line 25 of a 3270 terminal (or a PC emulating a 3270) for various kinds of protocol violations and "unexpected" error conditions (including connection to a {down} computer). On a PC, simulated with `->/_', with the two center characters overstruck. Note: to appreciate this term fully, it helps to know that "broken arrow" is also military jargon for an accident involving nuclear weapons.... :broken-ring network: Pejorative hackerism for "token-ring network", an early and very slow LAN technology from IBM that lost the standards war to Ethernet. Though token-ring survives in a few niche markets (such as factory automation) that put a high premium on resistance to electrical noise, the term is now (2000) primarily historical. :BrokenWindows: n. Abusive hackerism for the {crufty} and {elephantine} {X} environment on Sun machines; properly called `OpenWindows'. :broket: /broh´k@t/, /broh´ket`/, n. [rare; by analogy with `bracket': a `broken bracket'] Either of the characters < and >, when used as paired enclosing delimiters. This word originated as a contraction of the phrase `broken bracket', that is, a bracket that is bent in the middle. (At MIT, and apparently in the {Real World} as well, these are usually called {angle brackets}.) :Brooks's Law: prov. "Adding manpower to a late software project makes it later" -- a result of the fact that the expected advantage from splitting development work among N programmers is O(N) (that is, proportional to N), but the complexity and communications cost associated with coordinating and then merging their work is O(N^2) (that is, proportional to the square of N). The quote is from Fred Brooks, a manager of IBM's OS/360 project and author of The Mythical Man-Month (Addison-Wesley, 1975, ISBN 0-201-00650-2), an excellent early book on software engineering. The myth in question has been most tersely expressed as "Programmer time is fungible" and Brooks established conclusively that it is not. Hackers have never forgotten his advice (though it's not the whole story; see {bazaar}); too often, {management} still does. See also {creationism}, {second-system effect}, {optimism}. :brown-paper-bag bug: n. A bug in a public software release that is so embarrassing that the author notionally wears a brown paper bag over his head for a while so he won't be recognized on the net. Entered popular usage after the early-1999 release of the first Linux 2.2, which had one. The phrase was used in Linus Torvalds's apology posting. :browser: n. A program specifically designed to help users view and navigate hypertext, on-line documentation, or a database. While this general sense has been present in jargon for a long time, the proliferation of browsers for the World Wide Web after 1992 has made it much more popular and provided a central or default techspeak meaning of the word previously lacking in hacker usage. Nowadays, if someone mentions using a `browser' without qualification, one may assume it is a Web browser. :BRS: /B·R·S/, n. Syn. {Big Red Switch}. This abbreviation is fairly common on-line. :brute force: adj. Describes a primitive programming style, one in which the programmer relies on the computer's processing power instead of using his or her own intelligence to simplify the problem, often ignoring problems of scale and applying naive methods suited to small problems directly to large ones. The term can also be used in reference to programming style: brute-force programs are written in a heavyhanded, tedious way, full of repetition and devoid of any elegance or useful abstraction (see also {brute force and ignorance}). The {canonical} example of a brute-force algorithm is associated with the `traveling salesman problem' (TSP), a classical {NP-}hard problem: Suppose a person is in, say, Boston, and wishes to drive to N other cities. In what order should the cities be visited in order to minimize the distance travelled? The brute-force method is to simply generate all possible routes and compare the distances; while guaranteed to work and simple to implement, this algorithm is clearly very stupid in that it considers even obviously absurd routes (like going from Boston to Houston via San Francisco and New York, in that order). For very small N it works well, but it rapidly becomes absurdly inefficient when N increases (for N = 15, there are already 1,307,674,368,000 possible routes to consider, and for N = 1000 -- well, see {bignum}). Sometimes, unfortunately, there is no better general solution than brute force. See also {NP-} and {rubber-hose cryptanalysis}. A more simple-minded example of brute-force programming is finding the smallest number in a large list by first using an existing program to sort the list in ascending order, and then picking the first number off the front. Whether brute-force programming should actually be considered stupid or not depends on the context; if the problem is not terribly big, the extra CPU time spent on a brute-force solution may cost less than the programmer time it would take to develop a more `intelligent' algorithm. Additionally, a more intelligent algorithm may imply more long-term complexity cost and bug-chasing than are justified by the speed improvement. Ken Thompson, co-inventor of Unix, is reported to have uttered the epigram "When in doubt, use brute force". He probably intended this as a {ha ha only serious}, but the original Unix kernel's preference for simple, robust, and portable algorithms over {brittle} `smart' ones does seem to have been a significant factor in the success of that OS. Like so many other tradeoffs in software design, the choice between brute force and complex, finely-tuned cleverness is often a difficult one that requires both engineering savvy and delicate esthetic judgment. :brute force and ignorance: n. A popular design technique at many software houses -- {brute force} coding unrelieved by any knowledge of how problems have been previously solved in elegant ways. Dogmatic adherence to design methodologies tends to encourage this sort of thing. Characteristic of early {larval stage} programming; unfortunately, many never outgrow it. Often abbreviated BFI: "Gak, they used a {bubble sort}! That's strictly from BFI." Compare {bogosity}. A very similar usage is said to be mainstream in Great Britain. :BSD: /B·S·D/, n. [abbreviation for `Berkeley Software Distribution'] a family of {Unix} versions for the {DEC} {VAX} and {PDP-11} developed by Bill Joy and others at {Berzerkeley} starting around 1977, incorporating paged virtual memory, TCP/IP networking enhancements, and many other features. The BSD versions (4.1, 4.2, and 4.3) and the commercial versions derived from them (SunOS, ULTRIX, and Mt. Xinu) held the technical lead in the Unix world until AT&T's successful standardization efforts after about 1986; descendants including Free/Open/NetBSD, BSD/OS and MacOS X are still widely popular. Note that BSD versions going back to 2.9 are often referred to by their version numbers alone, without the BSD prefix. See also {Unix}. :BSOD: /B·S·O·D/ Very common abbreviation for {Blue Screen of Death}. Both spoken and written. :BUAF: //, n. [abbreviation, from alt.fan.warlord] Big Ugly ASCII Font -- a special form of {ASCII art}. Various programs exist for rendering text strings into block, bloob, and pseudo-script fonts in cells between four and six character cells on a side; this is smaller than the letters generated by older {banner} (sense 2) programs. These are sometimes used to render one's name in a {sig block}, and are critically referred to as BUAFs. See {warlording}. :BUAG: //, n. [abbreviation, from alt.fan.warlord] Big Ugly ASCII Graphic. Pejorative term for ugly {ASCII art}, especially as found in {sig block}s. For some reason, mutations of the head of Bart Simpson are particularly common in the least imaginative {sig block}s. See {warlording}. :bubble sort: n. Techspeak for a particular sorting technique in which pairs of adjacent values in the list to be sorted are compared and interchanged if they are out of order; thus, list entries `bubble upward' in the list until they bump into one with a lower sort value. Because it is not very good relative to other methods and is the one typically stumbled on by {naive} and untutored programmers, hackers consider it the {canonical} example of a naive algorithm. (However, it's been shown by repeated experiment that below about 5000 records bubble-sort is OK anyway.) The canonical example of a really bad algorithm is {bogo-sort}. A bubble sort might be used out of ignorance, but any use of bogo-sort could issue only from brain damage or willful perversity. :bucky bits: /buh´kee bits/, n. 1. [obs.] The bits produced by the CONTROL and META shift keys on a SAIL keyboard (octal 200 and 400 respectively), resulting in a 9-bit keyboard character set. The MIT AI TV (Knight) keyboards extended this with TOP and separate left and right CONTROL and META keys, resulting in a 12-bit character set; later, LISP Machines added such keys as SUPER, HYPER, and GREEK (see {space-cadet keyboard}). 2. By extension, bits associated with `extra' shift keys on any keyboard, e.g., the ALT on an IBM PC or command and option keys on a Macintosh. It has long been rumored that bucky bits were named for Buckminster Fuller during a period when he was consulting at Stanford. Actually, bucky bits were invented by Niklaus Wirth when he was at Stanford in 1964--65; he first suggested the idea of an EDIT key to set the 8th bit of an otherwise 7-bit ASCII character). It seems that, unknown to Wirth, certain Stanford hackers had privately nicknamed him `Bucky' after a prominent portion of his dental anatomy, and this nickname transferred to the bit. Bucky-bit commands were used in a number of editors written at Stanford, including most notably TV-EDIT and NLS. The term spread to MIT and CMU early and is now in general use. Ironically, Wirth himself remained unaware of its derivation for nearly 30 years, until GLS dug up this history in early 1993! See {double bucky}, {quadruple bucky}. :buffer chuck: n. Shorter and ruder syn. for {buffer overflow}. :buffer overflow: n. What happens when you try to stuff more data into a buffer (holding area) than it can handle. This problem is commonly exploited by {cracker}s to get arbitrary commands executed by a program running with root permissions. This may be due to a mismatch in the processing rates of the producing and consuming processes (see {overrun} and {firehose syndrome}), or because the buffer is simply too small to hold all the data that must accumulate before a piece of it can be processed. For example, in a text-processing tool that {crunch}es a line at a time, a short line buffer can result in {lossage} as input from a long line overflows the buffer and trashes data beyond it. Good defensive programming would check for overflow on each character and stop accepting data when the buffer is full up. The term is used of and by humans in a metaphorical sense. "What time did I agree to meet you? My buffer must have overflowed." Or "If I answer that phone my buffer is going to overflow." See also {spam}, {overrun screw}. :bug: n. An unwanted and unintended property of a program or piece of hardware, esp. one that causes it to malfunction. Antonym of {feature}. Examples: "There's a bug in the editor: it writes things out backwards." "The system crashed because of a hardware bug." "Fred is a winner, but he has a few bugs" (i.e., Fred is a good guy, but he has a few personality problems). Historical note: Admiral Grace Hopper (an early computing pioneer better known for inventing {COBOL}) liked to tell a story in which a technician solved a {glitch} in the Harvard Mark II machine by pulling an actual insect out from between the contacts of one of its relays, and she subsequently promulgated {bug} in its hackish sense as a joke about the incident (though, as she was careful to admit, she was not there when it happened). For many years the logbook associated with the incident and the actual bug in question (a moth) sat in a display case at the Naval Surface Warfare Center (NSWC). The entire story, with a picture of the logbook and the moth taped into it, is recorded in the Annals of the History of Computing, Vol. 3, No. 3 (July 1981), pp. 285--286. The text of the log entry (from September 9, 1947), reads "1545 Relay #70 Panel F (moth) in relay. First actual case of bug being found". This wording establishes that the term was already in use at the time in its current specific sense -- and Hopper herself reports that the term bug was regularly applied to problems in radar electronics during WWII. [bugpic.png] The `original bug' Indeed, the use of bug to mean an industrial defect was already established in Thomas Edison's time, and a more specific and rather modern use can be found in an electrical handbook from 1896 (Hawkin's New Catechism of Electricity, Theo. Audel & Co.) which says: "The term `bug' is used to a limited extent to designate any fault or trouble in the connections or working of electric apparatus." It further notes that the term is "said to have originated in quadruplex telegraphy and have been transferred to all electric apparatus." The latter observation may explain a common folk etymology of the term; that it came from telephone company usage, in which "bugs in a telephone cable" were blamed for noisy lines. Though this derivation seems to be mistaken, it may well be a distorted memory of a joke first current among telegraph operators more than a century ago! Or perhaps not a joke. Historians of the field inform us that the term "bug" was regularly used in the early days of telegraphy to refer to a variety of semi-automatic telegraphy keyers that would send a string of dots if you held them down. In fact, the Vibroplex keyers (which were among the most common of this type) even had a graphic of a beetle on them (and still do)! While the ability to send repeated dots automatically was very useful for professional morse code operators, these were also significantly trickier to use than the older manual keyers, and it could take some practice to ensure one didn't introduce extraneous dots into the code by holding the key down a fraction too long. In the hands of an inexperienced operator, a Vibroplex "bug" on the line could mean that a lot of garbled Morse would soon be coming your way. Further, the term "bug" has long been used among radio technicians to describe a device that converts electromagnetic field variations into acoustic signals. It is used to trace radio interference and look for dangerous radio emissions. Radio community usage derives from the roach-like shape of the first versions used by 19th century physicists. The first versions consisted of a coil of wire (roach body), with the two wire ends sticking out and bent back to nearly touch forming a spark gap (roach antennae). The bug is to the radio technician what the stethoscope is to the stereotypical medical doctor. This sense is almost certainly ancestral to modern use of "bug" for a covert monitoring device, but may also have contributed to the use of "bug" for the effects of radio interference itself. Actually, use of bug in the general sense of a disruptive event goes back to Shakespeare! (Henry VI, part III - Act V, Scene II: King Edward: "So, lie thou there. Die thou; and die our fear; For Warwick was a bug that fear'd us all.") In the first edition of Samuel Johnson's dictionary one meaning of bug is "A frightful object; a walking spectre"; this is traced to `bugbear', a Welsh term for a variety of mythological monster which (to complete the circle) has recently been reintroduced into the popular lexicon through fantasy role-playing games. In any case, in jargon the word almost never refers to insects. Here is a plausible conversation that never actually happened: "There is a bug in this ant farm!" "What do you mean? I don't see any ants in it." "That's the bug." A careful discussion of the etymological issues can be found in a paper by Fred R. Shapiro, 1987, "Entomology of the Computer Bug: History and Folklore", American Speech 62(4):376-378. [There has been a widespread myth that the original bug was moved to the Smithsonian, and an earlier version of this entry so asserted. A correspondent who thought to check discovered that the bug was not there. While investigating this in late 1990, your editor discovered that the NSWC still had the bug, but had unsuccessfully tried to get the Smithsonian to accept it -- and that the present curator of their History of American Technology Museum didn't know this and agreed that it would make a worthwhile exhibit. It was moved to the Smithsonian in mid-1991, but due to space and money constraints was not actually exhibited for years afterwards. Thus, the process of investigating the original-computer-bug bug fixed it in an entirely unexpected way, by making the myth true! --ESR] [73-07-29.png] It helps to remember that this dates from 1973. (The next cartoon in the Crunchly saga is 73-10-31) :bug-compatible: adj. [common] Said of a design or revision that has been badly compromised by a requirement to be compatible with {fossil}s or {misfeature}s in other programs or (esp.) previous releases of itself. "MS-DOS 2.0 used \ as a path separator to be bug-compatible with some cretin's choice of / as an option character in 1.0." :bug-for-bug compatible: n. Same as {bug-compatible}, with the additional implication that much tedious effort went into ensuring that each (known) bug was replicated. :bug-of-the-month club: n. [from "book-of-the-month club", a time-honored mail-order-marketing technique in the U.S.] A mythical club which users of sendmail(8) (the Unix mail daemon) belong to; this was coined on the Usenet newsgroup comp.security.unix at a time when sendmail security holes, which allowed outside {cracker}s access to the system, were being uncovered at an alarming rate, forcing sysadmins to update very often. Also, more completely, fatal security bug-of-the-month club. See also {kernel-of-the-week club}. :bulletproof: adj. Used of an algorithm or implementation considered extremely {robust}; lossage-resistant; capable of correctly recovering from any imaginable exception condition -- a rare and valued quality. Implies that the programmer has thought of all possible errors, and added {code} to protect against each one. Thus, in some cases, this can imply code that is too heavyweight, due to excessive paranoia on the part of the programmer. Syn. {armor-plated}. :bullschildt: /bul´shilt/, n. [comp.lang.c on USENET] A confident, but incorrect, statement about a programming language. This immortalizes a very bad book about {C}, Herbert Schildt's C - The Complete Reference. One reviewer commented "The naive errors in this book would be embarrassing even in a programming assignment turned in by a computer science college sophomore." :bump: vt. Synonym for increment. Has the same meaning as C's ++ operator. Used esp. of counter variables, pointers, and index dummies in for, while, and do-while loops. :burble: v. [from Lewis Carroll's Jabberwocky] Like {flame}, but connotes that the source is truly clueless and ineffectual (mere flamers can be competent). A term of deep contempt. "There's some guy on the phone burbling about how he got a DISK FULL error and it's all our comm software's fault." This is mainstream slang in some parts of England. :buried treasure: n. A surprising piece of code found in some program. While usually not wrong, it tends to vary from {crufty} to {bletcherous}, and has lain undiscovered only because it was functionally correct, however horrible it is. Used sarcastically, because what is found is anything but treasure. Buried treasure almost always needs to be dug up and removed. "I just found that the scheduler sorts its queue using {bubble sort}! Buried treasure!" :burn a CD: v. To write a software or document distribution on a CDR. Coined from the fact that a laser is used to inscribe the information by burning small pits in the medium, and from the fact that disk comes out of the drive warm to the touch. Writable CDs can be done on a normal desk-top machine with a suitable drive (so there is no protracted release cycle associated with making them) but each one takes a long time to make, so they are not appropriate for volume production. Writable CDs are suitable for software backups and for short-turnaround-time low-volume software distribution, such as sending a beta release version to a few selected field test sites. Compare {cut a tape}. :burn-in period: n. 1. A factory test designed to catch systems with {marginal} components before they get out the door; the theory is that burn-in will protect customers by outwaiting the steepest part of the {bathtub curve} (see {infant mortality}). 2. A period of indeterminate length in which a person using a computer is so intensely involved in his project that he forgets basic needs such as food, drink, sleep, etc. Warning: Excessive burn-in can lead to burn-out. See {hack mode}, {larval stage}. Historical note: the origin of "burn-in" (sense 1) is apparently the practice of setting a new-model airplane's brakes on fire, then extinguishing the fire, in order to make them hold better. This was done on the first version of the U.S. spy-plane, the U-2. :burst page: n. Syn. {banner}, sense 1. :busy-wait: vi. Used of human behavior, conveys that the subject is busy waiting for someone or something, intends to move instantly as soon as it shows up, and thus cannot do anything else at the moment. "Can't talk now, I'm busy-waiting till Bill gets off the phone." Technically, busy-wait means to wait on an event by {spin}ning through a tight or timed-delay loop that polls for the event on each pass, as opposed to setting up an interrupt handler and continuing execution on another part of the task. In applications this is a wasteful technique, and best avoided on timesharing systems where a busy-waiting program may {hog} the processor. However, it is often unavoidable in kernel programming. In the Linux world, kernel busy-waits are usually referred to as spinlocks. :buzz: vi. 1. Of a program, to run with no indication of progress and perhaps without guarantee of ever finishing; esp. said of programs thought to be executing tight loops of code. A program that is buzzing appears to be {catatonic}, but never gets out of catatonia, while a buzzing loop may eventually end of its own accord. "The program buzzes for about 10 seconds trying to sort all the names into order." See {spin}; see also {grovel}. 2. [ETA Systems] To test a wire or printed circuit trace for continuity, esp. by applying an AC rather than DC signal. Some wire faults will pass DC tests but fail an AC buzz test. 3. To process an array or list in sequence, doing the same thing to each element. "This loop buzzes through the tz array looking for a terminator type." :buzzword-compliant: [also buzzword-enabled] Used (disparagingly) of products that seem to have been specified to incorporate all of this month's trendy technologies. Key buzzwords that often show up in buzzword-compliant specifications as of 2001 include `XML', `Java', `peer-to-peer', `distributed', and `open'. :BWQ: /B·W·Q/, n. [IBM: abbreviation, `Buzz Word Quotient'] The percentage of buzzwords in a speech or documents. Usually roughly proportional to {bogosity}. See {TLA}. :by hand: adv. 1. [common] Said of an operation (especially a repetitive, trivial, and/or tedious one) that ought to be performed automatically by the computer, but which a hacker instead has to step tediously through. "My mailer doesn't have a command to include the text of the message I'm replying to, so I have to do it by hand." This does not necessarily mean the speaker has to retype a copy of the message; it might refer to, say, dropping into a subshell from the mailer, making a copy of one's mailbox file, reading that into an editor, locating the top and bottom of the message in question, deleting the rest of the file, inserting `>' characters on each line, writing the file, leaving the editor, returning to the mailer, reading the file in, and later remembering to delete the file. Compare {eyeball search}. 2. [common] By extension, writing code which does something in an explicit or low-level way for which a presupplied library routine ought to have been available. "This cretinous B-tree library doesn't supply a decent iterator, so I'm having to walk the trees by hand." :byte: /bi:t/, n. [techspeak] A unit of memory or data equal to the amount used to represent one character; on modern architectures this is invariably 8 bits. Some older architectures used byte for quantities of 6, 7, or (especially) 9 bits, and the PDP-10 supported bytes that were actually bitfields of 1 to 36 bits! These usages are now obsolete, killed off by universal adoption of power-of-2 word sizes. Historical note: The term was coined by Werner Buchholz in 1956 during the early design phase for the IBM Stretch computer; originally it was described as 1 to 6 bits (typical I/O equipment of the period used 6-bit chunks of information). The move to an 8-bit byte happened in late 1956, and this size was later adopted and promulgated as a standard by the System/360. The word was coined by mutating the word `bite' so it would not be accidentally misspelled as {bit}. See also {nybble}. :byte sex: n. [common] The byte sex of hardware is {big-endian} or {little-endian}; see those entries. :bytesexual: /bi:t`sek´shu·@l/, adj. [rare] Said of hardware, denotes willingness to compute or pass data in either {big-endian} or {little-endian} format (depending, presumably, on a {mode bit} somewhere). See also {NUXI problem}. :Bzzzt! Wrong.: /bzt rong/, excl. [common; Usenet/Internet; punctuation varies] From a Robin Williams routine in the movie Dead Poets Society spoofing radio or TV quiz programs, such as Truth or Consequences, where an incorrect answer earns one a blast from the buzzer and condolences from the interlocutor. A way of expressing mock-rude disagreement, usually immediately following an included quote from another poster. The less abbreviated "*Bzzzzt*, wrong, but thank you for playing" is also common; capitalization and emphasis of the buzzer sound varies.

The third letter of the English alphabet. 2. ASCII 1000011. 3. The name of a programming language designed by Dennis Ritchie during the early 1970s and immediately used to reimplement {Unix}; so called because many features derived from an earlier compiler named `B' in commemoration of its parent, BCPL. (BCPL was in turn descended from an earlier Algol-derived language, CPL.) Before Bjarne Stroustrup settled the question by designing {C++}, there was a humorous debate over whether C's successor should be named `D' or `P'. C became immensely popular outside Bell Labs after about 1980 and is now the dominant language in systems and microcomputer applications programming. C is often described, with a mixture of fondness and disdain varying according to the speaker, as "a language that combines all the elegance and power of assembly language with all the readability and maintainability of assembly language" See also {languages of choice}, {indent style}. [ansi-c.png] The Crunchly on the left sounds a little ANSI. :C Programmer's Disease: n. The tendency of the undisciplined C programmer to set arbitrary but supposedly generous static limits on table sizes (defined, if you're lucky, by constants in header files) rather than taking the trouble to do proper dynamic storage allocation. If an application user later needs to put 68 elements into a table of size 50, the afflicted programmer reasons that he or she can easily reset the table size to 68 (or even as much as 70, to allow for future expansion) and recompile. This gives the programmer the comfortable feeling of having made the effort to satisfy the user's (unreasonable) demands, and often affords the user multiple opportunities to explore the marvelous consequences of {fandango on core}. In severe cases of the disease, the programmer cannot comprehend why each fix of this kind seems only to further disgruntle the user. :C&C: // [common, esp. on news.admin.net-abuse.email] Contraction of "Coffee & Cats". This frequently occurs as a warning label on USENET posts that are likely to cause you to {snarf} coffee onto your keyboard and startle the cat off your lap. :C++: /C'·pluhs·pluhs/, n. Designed by Bjarne Stroustrup of AT&T Bell Labs as a successor to {C}. Now one of the {languages of choice}, although many hackers still grumble that it is the successor to either Algol 68 or Ada (depending on generation), and a prime example of {second-system effect}. Almost anything that can be done in any language can be done in C++, but it requires a {language lawyer} to know what is and what is not legal -- the design is almost too large to hold in even hackers' heads. Much of the {cruft} results from C++'s attempt to be backward compatible with C. Stroustrup himself has said in his retrospective book The Design and Evolution of C++ (p. 207), "Within C++, there is a much smaller and cleaner language struggling to get out." [Many hackers would now add "Yes, and it's called {Java}" --ESR] :calculator: n. Syn. for {bitty box}. :Camel Book: n. Universally recognized nickname for the book Programming Perl, by Larry Wall and Randal L. Schwartz, O'Reilly and Associates 1991, ISBN 0-937175-64-1 (second edition 1996, ISBN 1-56592-149-6; third edition 2000, 0-596-00027-8, adding as authors Tom Christiansen and Jon Orwant but dropping Randal Schwartz). The definitive reference on {Perl}. :camelCase: A variable in a programming language is sait to be camelCased when all words but the first are capitalized. This practice contrasts with the C tradition of either running syllables together or marking syllable breaks with underscores; thus, where a C programmer would write thisverylongname or this_very_long_name, the camelCased version would be thisVeryLongName. This practice is common in certain language communities (formerly Pascal; today Java and Visual Basic) and tends to be associated with object-oriented programming. Compare {BiCapitalization}; but where that practice is primarily associated with marketing, camelCasing is not aimed at impressing anybody, and hackers consider it respectable. :camelCasing: See {PascalCasing}. :can't happen: The traditional program comment for code executed under a condition that should never be true, for example a file size computed as negative. Often, such a condition being true indicates data corruption or a faulty algorithm; it is almost always handled by emitting a fatal error message and terminating or crashing, since there is little else that can be done. Some case variant of "can't happen" is also often the text emitted if the `impossible' error actually happens! Although "can't happen" events are genuinely infrequent in production code, programmers wise enough to check for them habitually are often surprised at how frequently they are triggered during development and how many headaches checking for them turns out to head off. See also {firewall code} (sense 2). :cancelbot: /kan´sel·bot/ [Usenet: compound, cancel + robot] 1. Mythically, a {robocanceller} 2. In reality, most cancelbots are manually operated by being fed lists of spam message IDs. :Cancelmoose[tm]: /kan´sel·moos/ [Usenet] The archetype and model of all good {spam}-fighters. Once upon a time, the 'Moose would send out spam-cancels and then post notice anonymously to news.admin.policy, news.admin.misc, and alt.current-events.net-abuse. The 'Moose stepped to the fore on its own initiative, at a time (mid-1994) when spam-cancels were irregular and disorganized, and behaved altogether admirably -- fair, even-handed, and quick to respond to comments and criticism, all without self-aggrandizement or martyrdom. Cancelmoose[tm] quickly gained near-unanimous support from the readership of all three above-mentioned groups. Nobody knows who Cancelmoose[tm] really is, and there aren't even any good rumors. However, the 'Moose now has an e-mail address () and a web site (http://www.cm.org/.) By early 1995, others had stepped into the spam-cancel business, and appeared to be comporting themselves well, after the 'Moose's manner. The 'Moose has now gotten out of the business, and is more interested in ending spam (and cancels) entirely. :candygrammar: n. A programming-language grammar that is mostly {syntactic sugar}; the term is also a play on `candygram'. {COBOL}, Apple's Hypertalk language, and a lot of the so-called `4GL' database languages share this property. The usual intent of such designs is that they be as English-like as possible, on the theory that they will then be easier for unskilled people to program. This intention comes to grief on the reality that syntax isn't what makes programming hard; it's the mental effort and organization required to specify an algorithm precisely that costs. Thus the invariable result is that `candygrammar' languages are just as difficult to program in as terser ones, and far more painful for the experienced hacker. [The overtones from the old Chevy Chase skit on Saturday Night Live should not be overlooked. This was a Jaws parody. Someone lurking outside an apartment door tries all kinds of bogus ways to get the occupant to open up, while ominous music plays in the background. The last attempt is a half-hearted "Candygram!" When the door is opened, a shark bursts in and chomps the poor occupant. [There is a similar gag in "Blazing Saddles" --ESR] There is a moral here for those attracted to candygrammars. Note that, in many circles, pretty much the same ones who remember Monty Python sketches, all it takes is the word "Candygram!", suitably timed, to get people rolling on the floor. -- GLS] :canonical: adj. [very common; historically, `according to religious law'] The usual or standard state or manner of something. This word has a somewhat more technical meaning in mathematics. Two formulas such as 9 + x and x + 9 are said to be equivalent because they mean the same thing, but the second one is in canonical form because it is written in the usual way, with the highest power of x first. Usually there are fixed rules you can use to decide whether something is in canonical form. The jargon meaning, a relaxation of the technical meaning, acquired its present loading in computer-science culture largely through its prominence in Alonzo Church's work in computation theory and mathematical logic (see {Knights of the Lambda Calculus}). Compare {vanilla}. Non-technical academics do not use the adjective `canonical' in any of the senses defined above with any regularity; they do however use the nouns canon and canonicity (not **canonicalness or **canonicality). The canon of a given author is the complete body of authentic works by that author (this usage is familiar to Sherlock Holmes fans as well as to literary scholars). `The canon' is the body of works in a given field (e.g., works of literature, or of art, or of music) deemed worthwhile for students to study and for scholars to investigate. The word `canon' has an interesting history. It derives ultimately from the Greek kanon (akin to the English `cane') referring to a reed. Reeds were used for measurement, and in Latin and later Greek the word `canon' meant a rule or a standard. The establishment of a canon of scriptures within Christianity was meant to define a standard or a rule for the religion. The above non-techspeak academic usages stem from this instance of a defined and accepted body of work. Alongside this usage was the promulgation of `canons' (`rules') for the government of the Catholic Church. The techspeak usages ("according to religious law") derive from this use of the Latin `canon'. Hackers invest this term with a playfulness that makes an ironic contrast with its historical meaning. A true story: One Bob Sjoberg, new at the MIT AI Lab, expressed some annoyance at the incessant use of jargon. Over his loud objections, GLS and RMS made a point of using as much of it as possible in his presence, and eventually it began to sink in. Finally, in one conversation, he used the word canonical in jargon-like fashion without thinking. Steele: "Aha! We've finally got you talking jargon too!" Stallman: "What did he say?" Steele: "Bob just used `canonical' in the canonical way." Of course, canonicality depends on context, but it is implicitly defined as the way hackers normally expect things to be. Thus, a hacker may claim with a straight face that `according to religious law' is not the canonical meaning of canonical. :careware: /keir´weir/, n. A variety of {shareware} for which either the author suggests that some payment be made to a nominated charity or a levy directed to charity is included on top of the distribution charge. Syn.: {charityware}; compare {crippleware}, sense 2. :cargo cult programming: n. A style of (incompetent) programming dominated by ritual inclusion of code or program structures that serve no real purpose. A cargo cult programmer will usually explain the extra code as a way of working around some bug encountered in the past, but usually neither the bug nor the reason the code apparently avoided the bug was ever fully understood (compare {shotgun debugging}, {voodoo programming}). The term `cargo cult' is a reference to aboriginal religions that grew up in the South Pacific after World War II. The practices of these cults center on building elaborate mockups of airplanes and military style landing strips in the hope of bringing the return of the god-like airplanes that brought such marvelous cargo during the war. Hackish usage probably derives from Richard Feynman's characterization of certain practices as "cargo cult science" in his book Surely You're Joking, Mr. Feynman! (W. W. Norton & Co, New York 1985, ISBN 0-393-01921-7). :cascade: n. 1. A huge volume of spurious error-message output produced by a compiler with poor error recovery. Too frequently, one trivial syntax error (such as a missing `)' or `}') throws the parser out of synch so that much of the remaining program text is interpreted as garbaged or ill-formed. 2. A chain of Usenet followups, each adding some trivial variation or riposte to the text of the previous one, all of which is reproduced in the new message; an {include war} in which the object is to create a sort of communal graffito. :case and paste: n. [from `cut and paste'] The addition of a new {feature} to an existing system by selecting the code from an existing feature and pasting it in with minor changes. Common in telephony circles because most operations in a telephone switch are selected using case statements. Leads to {software bloat}. In some circles of EMACS users this is called `programming by Meta-W', because Meta-W is the EMACS command for copying a block of text to a kill buffer in preparation to pasting it in elsewhere. The term is condescending, implying that the programmer is acting mindlessly rather than thinking carefully about what is required to integrate the code for two similar cases. At {DEC} (now HP), this is sometimes called clone-and-hack coding. :case mod: [from `case modification'] 1. Originally a kind of hardware hack on a PC intended to support {overclocking} (e.g. with cutouts for oversized fans, or a freon-based or water-cooling system). 2. Nowadays, similar drastic surgery that's done just to make a machine look nifty. The commonest case mods combine acrylic case windows with LEDs to give the machine an eerie interior glow like a B-movie flying saucer. More advanced forms of case modding involve building machines into weird and unlikely shapes. The effect can be quite artistic, but one of the unwritten rules is that the machine must continue to function as a computer. :casters-up mode: n. [IBM, prob. fr. slang belly up] Yet another synonym for `broken' or `down'. Usually connotes a major failure. A system (hardware or software) which is down may be already being restarted before the failure is noticed, whereas one which is casters up is usually a good excuse to take the rest of the day off (as long as you're not responsible for fixing it). :casting the runes: n. What a {guru} does when you ask him or her to run a particular program and type at it because it never works for anyone else; esp. used when nobody can ever see what the guru is doing different from what J. Random Luser does. Compare {incantation}, {runes}, {examining the entrails}; also see the AI koan about Tom Knight in Some AI Koans (in Appendix A). A correspondent from England tells us that one of ICL's most talented systems designers used to be called out occasionally to service machines which the {field circus} had given up on. Since he knew the design inside out, he could often find faults simply by listening to a quick outline of the symptoms. He used to play on this by going to some site where the field circus had just spent the last two weeks solid trying to find a fault, and spreading a diagram of the system out on a table top. He'd then shake some chicken bones and cast them over the diagram, peer at the bones intently for a minute, and then tell them that a certain module needed replacing. The system would start working again immediately upon the replacement. :cat: vt. [from catenate via {Unix} cat(1)] 1. [techspeak] To spew an entire file to the screen or some other output sink without pause (syn. {blast}). 2. By extension, to dump large amounts of data at an unprepared target or with no intention of browsing it carefully. Usage: considered silly. Rare outside Unix sites. See also {dd}, {BLT}. Among Unix fans, cat(1) is considered an excellent example of user-interface design, because it delivers the file contents without such verbosity as spacing or headers between the files, and because it does not require the files to consist of lines of text, but works with any sort of data. Among Unix haters, cat(1) is considered the {canonical} example of bad user-interface design, because of its woefully unobvious name. It is far more often used to {blast} a file to standard output than to concatenate two files. The name cat for the former operation is just as unintuitive as, say, LISP's {cdr}. Of such oppositions are {holy wars} made.... See also {UUOC}. :catatonic: adj. Describes a condition of suspended animation in which something is so {wedged} or {hung} that it makes no response. If you are typing on a terminal and suddenly the computer doesn't even echo the letters back to the screen as you type, let alone do what you're asking it to do, then the computer is suffering from catatonia (possibly because it has crashed). "There I was in the middle of a winning game of {nethack} and it went catatonic on me! Aaargh!" Compare {buzz}. :cathedral: n.,adj. [see {bazaar} for derivation] The `classical' mode of software engineering long thought to be necessarily implied by {Brooks's Law}. Features small teams, tight project control, and long release intervals. This term came into use after analysis of the Linux experience suggested there might be something wrong (or at least incomplete) in the classical assumptions. :cd tilde: /C·D til·d@/, vi. To go home. From the Unix C-shell and Korn-shell command cd ~, which takes one to one's $HOME (cd with no arguments happens to do the same thing). By extension, may be used with other arguments; thus, over an electronic chat link, cd ~coffee would mean "I'm going to the coffee machine." :CDA: /C·D·A/ The "Communications Decency Act", passed as section 502 of a major telecommunications reform bill on February 8th, 1996 ("Black Thursday"). The CDA made it a federal crime in the USA to send a communication which is "obscene, lewd, lascivious, filthy, or indecent, with intent to annoy, abuse, threaten, or harass another person." It also threatened with imprisonment anyone who "knowingly" makes accessible to minors any message that "describes, in terms patently offensive as measured by contemporary community standards, sexual or excretory activities or organs". While the CDA was sold as a measure to protect minors from the putative evils of pornography, the repressive political aims of the bill were laid bare by the Hyde amendment, which intended to outlaw discussion of abortion on the Internet. To say that this direct attack on First Amendment free-speech rights was not well received on the Internet would be putting it mildly. A firestorm of protest followed, including a February 29th 1996 mass demonstration by thousands of netters who turned their {home page}s black for 48 hours. Several civil-rights groups and computing/telecommunications companies mounted a constitutional challenge. The CDA was demolished by a strongly-worded decision handed down in 8th-circuit Federal court and subsequently affirmed by the U.S. Supreme Court on 26 June 1997 ("White Thursday"). See also {Exon}. :cdr: /ku´dr/, /kuh´dr/, vt. [from LISP] To skip past the first item from a list of things (generalized from the LISP operation on binary tree structures, which returns a list consisting of all but the first element of its argument). In the form cdr down, to trace down a list of elements: "Shall we cdr down the agenda?" Usage: silly. See also {loop through}. Historical note: The instruction format of the IBM 704 that hosted the original LISP implementation featured two 15-bit fields called the address and decrement parts. The term cdr was originally Contents of Decrement part of Register. Similarly, car stood for Contents of Address part of Register. The cdr and car operations have since become bases for formation of compound metaphors in non-LISP contexts. GLS recalls, for example, a programming project in which strings were represented as linked lists; the get-character and skip-character operations were of course called CHAR and CHDR. :chad: /chad/, n. 1. [common] The perforated edge strips on printer paper, after they have been separated from the printed portion. Also called {selvage}, {perf}, and {ripoff}. 2. The confetti-like paper bits punched out of cards or paper tape; this has also been called chaff, computer confetti, and keypunch droppings. It's reported that this was very old Army slang (associated with teletypewriters before the computer era), and has been occasionally sighted in directions for punched-card vote tabulators long after it passed out of live use among computer programmers in the late 1970s. This sense of `chad' returned to the mainstream during the finale of the hotly disputed U.S. presidential election in 2000 via stories about the Florida vote recounts. Note however that in the revived mainstream usage chad is not a mass noun and `a chad' is a single piece of the stuff. There is an urban legend that chad (sense 2) derives from the Chadless keypunch (named for its inventor), which cut little u-shaped tabs in the card to make a hole when the tab folded back, rather than punching out a circle/rectangle; it was clear that if the Chadless keypunch didn't make them, then the stuff that other keypunches made had to be `chad'. However, serious attempts to track down "Chadless" as a personal name or U.S. trademark have failed, casting doubt on this etymology -- and the U.S. Patent Classification System uses "chadless" (small c) as an adjective, suggesting that "chadless" derives from "chad" and not the other way around. There is another legend that the word was originally acronymic, standing for "Card Hole Aggregate Debris", but this has all the earmarks of a {backronym}. It has also been noted that the word "chad" is Scots dialect for gravel, but nobody has proposed any plausible reason that card chaff should be thought of as gravel. None of these etymologies is really plausible. [74-12-31.png] This is one way to be {chad}less. (The next cartoon in the Crunchly saga is 75-10-04) :chad box: n. A metal box about the size of a lunchbox (or in some models a large wastebasket), for collecting the {chad} (sense 2) that accumulated in {Iron Age} card punches. You had to open the covers of the card punch periodically and empty the chad box. The {bit bucket} was notionally the equivalent device in the CPU enclosure, which was typically across the room in another great gray-and-blue box. :chain: 1. vi. [orig. from BASIC's CHAIN statement] To hand off execution to a child or successor without going through the {OS} command interpreter that invoked it. The state of the parent program is lost and there is no returning to it. Though this facility used to be common on memory-limited micros and is still widely supported for backward compatibility, the jargon usage is semi-obsolescent; in particular, most Unix programmers will think of this as an {exec}. Oppose the more modern subshell. 2. n. A series of linked data areas within an operating system or application. Chain rattling is the process of repeatedly running through the linked data areas searching for one which is of interest to the executing program. The implication is that there is a very large number of links on the chain. :chainik: /chi:´nik/ [Russian, literally "teapot"] Almost synonymous with {muggle}. Implies both ignorance and a certain amount of willingness to learn, but does not necessarily imply as little experience or short exposure time as {newbie} and is not as derogatory as {luser}. Both a novice user and someone using a system for a long time without any understanding of the internals can be referred to as chainiks. Very widespread term in Russian hackish, often used in an English context by Russian-speaking hackers esp. in Israel (e.g. "Our new colleague is a complete chainik"). FidoNet discussion groups often had a "chainik" subsection for newbies and, well, old chainiks (eg. su.asm.chainik, ru.linux.chainik, ru.html.chainik). Public projects often have a chainik mailing list to keep the chainiks off the developers' and experienced users' discussions. Today, the word is slowly slipping into mainstream Russian due to the Russian translation of the popular yellow-black covered "foobar for dummies" series, which (correctly) uses "chainik" for "dummy", but its frequent (though not excessive) use is still characteristic hacker-speak. :channel: n. [IRC] The basic unit of discussion on {IRC}. Once one joins a channel, everything one types is read by others on that channel. Channels are named with strings that begin with a `#' sign and can have topic descriptions (which are generally irrelevant to the actual subject of discussion). Some notable channels are #initgame, #hottub, callahans, and #report. At times of international crisis, #report has hundreds of members, some of whom take turns listening to various news services and typing in summaries of the news, or in some cases, giving first-hand accounts of the action (e.g., Scud missile attacks in Tel Aviv during the Gulf War in 1991). :channel hopping: n. [common; IRC, GEnie] To rapidly switch channels on {IRC}, or a GEnie chat board, just as a social butterfly might hop from one group to another at a party. This term may derive from the TV watcher's idiom, channel surfing. :channel op: /chan´l op/, n. [IRC] Someone who is endowed with privileges on a particular {IRC} channel; commonly abbreviated chanop or CHOP or just op (as of 2000 these short forms have almost crowded out the parent usage). These privileges include the right to {kick} users, to change various status bits, and to make others into CHOPs. :chanop: /chan'·op/, n. [IRC] See {channel op}. :char: /keir/, /char/, /kar/, n. Shorthand for `character'. Esp.: used by C programmers, as char is C's typename for character data. :charityware: /cha´rit·ee·weir`/, n. Syn. {careware}. :chase pointers: 1. vi. To go through multiple levels of indirection, as in traversing a linked list or graph structure. Used esp. by programmers in C, where explicit pointers are a very common data type. This is techspeak, but it remains jargon when used of human networks. "I'm chasing pointers. Bob said you could tell me who to talk to about...." See {dangling pointer} and {snap}. 2. [Cambridge] pointer chase or pointer hunt: The process of going through a {core dump} (sense 1), interactively or on a large piece of paper printed with hex {runes}, following dynamic data-structures. Used only in a debugging context. :chawmp: n. [University of Florida] 16 or 18 bits (half of a machine word). This term was used by FORTH hackers during the late 1970s/early 1980s; it is said to have been archaic then, and may now be obsolete. It was coined in revolt against the promiscuous use of `word' for anything between 16 and 32 bits; `word' has an additional special meaning for FORTH hacks that made the overloading intolerable. For similar reasons, /gaw´bl/ (spelled `gawble' or possibly `gawbul') was in use as a term for 32 or 48 bits (presumably a full machine word, but our sources are unclear on this). These terms are more easily understood if one thinks of them as faithful phonetic spellings of `chomp' and `gobble' pronounced in a Florida or other Southern U.S. dialect. For general discussion of similar terms, see {nybble}. :check: n. A hardware-detected error condition, most commonly used to refer to actual hardware failures rather than software-induced traps. E.g., a parity check is the result of a hardware-detected parity error. Recorded here because the word often humorously extended to non-technical problems. For example, the term child check has been used to refer to the problems caused by a small child who is curious to know what happens when s/he presses all the cute buttons on a computer's console (of course, this particular problem could have been prevented with {molly-guard}s). :cheerfully: adv. See {happily}. :chemist: n. [Cambridge] Someone who wastes computer time on {number-crunching} when you'd far rather the machine were doing something more productive, such as working out anagrams of your name or printing Snoopy calendars or running {life} patterns. May or may not refer to someone who actually studies chemistry. :Chernobyl chicken: n. See {laser chicken}. :Chernobyl packet: /cher·noh´b@l pak'@t/, n. A network packet that induces a {broadcast storm} and/or {network meltdown}, in memory of the April 1986 nuclear accident at Chernobyl in Ukraine. The typical scenario involves an IP Ethernet datagram that passes through a gateway with both source and destination Ether and IP address set as the respective broadcast addresses for the subnetworks being gated between. Compare {Christmas tree packet}. :chicken head: n. [Commodore] The Commodore Business Machines logo, which strongly resembles a poultry part (within Commodore itself the logo was always called chicken lips). Rendered in ASCII as `C='. With the arguable exception of the {Amiga}, Commodore's machines were notoriously crocky little {bitty box}es, albeit people have written multitasking Unix-like operating systems with TCP/IP networking for them. Thus, this usage may owe something to Philip K. Dick's novel Do Androids Dream of Electric Sheep? (the basis for the movie Blade Runner; the novel is now sold under that title), in which a `chickenhead' is a mutant with below-average intelligence. :chickenboner: n. [spamfighters] Derogatory term for a spammer. The image that goes with it is of an overweight redneck with bad teeth living in a trailer, hunched in semi-darkness over his computer and surrounded by rotting chicken bones in half-eaten KFC buckets and empty beer cans. See http://www.spamfaq.net/terminology.shtml#chickenboner for discussion. :chiclet keyboard: n. A keyboard with a small, flat rectangular or lozenge-shaped rubber or plastic keys that look like pieces of chewing gum. (Chiclets is the brand name of a variety of chewing gum that does in fact resemble the keys of chiclet keyboards.) Used esp. to describe the original IBM PCjr keyboard. Vendors unanimously liked these because they were cheap, and a lot of early portable and laptop products got launched using them. Customers rejected the idea with almost equal unanimity, and chiclets are not often seen on anything larger than a digital watch any more. :Chinese Army technique: n. Syn. {Mongolian Hordes technique}. :choad: /chohd/, n. Synonym for `penis' used in alt.tasteless and popularized by the denizens thereof. They say: "We think maybe it's from Middle English but we're all too damned lazy to check the OED." [I'm not. It isn't. --ESR] This term is alleged to have been inherited through 1960s underground comics, and to have been recently sighted in the Beavis and Butthead cartoons. Speakers of the Hindi, Bengali and Gujarati languages have confirmed that `choad' is in fact an Indian vernacular word equivalent to `fuck'; it is therefore likely to have entered English slang via the British Raj. :choke: v. [common] To reject input, often ungracefully. "NULs make System V's lpr(1) choke." "I tried building an {EMACS} binary to use {X}, but cpp(1) choked on all those #defines." See {barf}, {vi}. :chomp: vi. 1. To {lose}; specifically, to chew on something of which more was bitten off than one can. Probably related to gnashing of teeth. 2. To bite the bag; See {bagbiter}. A hand gesture commonly accompanies this. To perform it, hold the four fingers together and place the thumb against their tips. Now open and close your hand rapidly to suggest a biting action (much like what Pac-Man does in the classic video game, though this pantomime seems to predate that). The gesture alone means `chomp chomp' (see Verb Doubling in the Jargon Construction section of the Prependices). The hand may be pointed at the object of complaint, and for real emphasis you can use both hands at once. Doing this to a person is equivalent to saying "You chomper!" If you point the gesture at yourself, it is a humble but humorous admission of some failure. You might do this if someone told you that a program you had written had failed in some surprising way and you felt dumb for not having anticipated it. :chomper: n. Someone or something that is chomping; a loser. See {loser}, {bagbiter}, {chomp}. :CHOP: /chop/, n. [IRC] See {channel op}. :Christmas tree: n. A kind of RS-232 line tester or breakout box featuring rows of blinking red and green LEDs suggestive of Christmas lights. :Christmas tree packet: n. A packet with every single option set for whatever protocol is in use. See {kamikaze packet}, {Chernobyl packet}. (The term doubtless derives from a fanciful image of each little option bit being represented by a different-colored light bulb, all turned on.) Compare {Godzillagram}. :chrome: n. [from automotive slang via wargaming] Showy features added to attract users but contributing little or nothing to the power of a system. "The 3D icons in Motif are just chrome, but they certainly are pretty chrome!" Distinguished from {bells and whistles} by the fact that the latter are usually added to gratify developers' own desires for featurefulness. Often used as a term of contempt. :chug: vi. To run slowly; to {grind} or {grovel}. "The disk is chugging like crazy." :Church of the SubGenius: n. A mutant offshoot of {Discordianism} launched in 1981 as a spoof of fundamentalist Christianity by the `Reverend' Ivan Stang, a brilliant satirist with a gift for promotion. Popular among hackers as a rich source of bizarre imagery and references such as "Bob" the divine drilling-equipment salesman, the Benevolent Space Xists, and the Stark Fist of Removal. Much SubGenius theory is concerned with the acquisition of the mystical substance or quality of {slack}. There is a home page at http://www.subgenius.com/. :CI$: //, n. Hackerism for `CIS', CompuServe Information Service. The dollar sign refers to CompuServe's rather steep line charges. Often used in {sig block}s just before a CompuServe address. Syn. {Compu$erve}. :Cinderella Book: n. [CMU] Introduction to Automata Theory, Languages, and Computation, by John Hopcroft and Jeffrey Ullman, (Addison-Wesley, 1979). So called because the cover depicts a girl (putatively Cinderella) sitting in front of a Rube Goldberg device and holding a rope coming out of it. On the back cover, the device is in shambles after she has (inevitably) pulled on the rope. See also {book titles}. :Classic C: /klas´ik C/, n. [a play on `Coke Classic'] The C programming language as defined in the first edition of {K&R}, with some small additions. It is also known as `K&R C'. The name came into use while C was being standardized by the ANSI X3J11 committee. Also `C Classic'. An analogous construction is sometimes applied elsewhere: thus, `X Classic', where X = Star Trek (referring to the original TV series) or X = PC (referring to IBM's ISA-bus machines as opposed to the PS/2 series). This construction is especially used of product series in which the newer versions are considered serious losers relative to the older ones. :clean: 1. adj. Used of hardware or software designs, implies `elegance in the small', that is, a design or implementation that may not hold any surprises but does things in a way that is reasonably intuitive and relatively easy to comprehend from the outside. The antonym is `grungy' or {crufty}. 2. v. To remove unneeded or undesired files in a effort to reduce clutter: "I'm cleaning up my account." "I cleaned up the garbage and now have 100 Meg free on that partition." :click of death: n. A syndrome of certain Iomega ZIP drives, named for the clicking noise that is caused by the malady. An affected drive will, after accepting a disk, will start making a clicking noise and refuse to eject the disk. A common solution for retrieving the disk is to insert the bent end of a paper clip into a small hole adjacent to the slot. "Clicked" disks are generally unusable after being retrieved from the drive. The clicking noise is caused by the drive's read/write head bumping against its movement stops when it fails to find track 0 on the disk, causing the head to become misaligned. This can happen when the drive has been subjected to a physical shock, or when the disk is exposed to an electromagnetic field, such as that of the CRT. Another common cause is when a package of disks is armed with an anti-theft strip at a store. When the clerk scans the product to disarm the strip, it can demagnetize the disks, wiping out track 0. There is evidence that the click of death is a communicable disease; a "clicked" disk can cause the read/write head of a "clean" drive to become misaligned. Iomega at first denied the existence of the click of death, but eventually offered to replace free of charge any drives affected by the condition. :CLM: /C·L·M/ [Sun: `Career Limiting Move'] 1. n. An action endangering one's future prospects of getting plum projects and raises, and possibly one's job: "His Halloween costume was a parody of his manager. He won the prize for `best CLM'." 2. adj. Denotes extreme severity of a bug, discovered by a customer and obviously missed earlier because of poor testing: "That's a CLM bug!" :clobber: vt. To overwrite, usually unintentionally: "I walked off the end of the array and clobbered the stack." Compare {mung}, {scribble}, {trash}, and {smash the stack}. :clock: n.,v. 1. [techspeak] The master oscillator that steps a CPU or other digital circuit through its paces. This has nothing to do with the time of day, although the software counter that keeps track of the latter may be derived from the former. 2. vt. To run a CPU or other digital circuit at a particular rate. "If you clock it at 1000MHz, it gets warm.". See {overclock}. 3. vt. To force a digital circuit from one state to the next by applying a single clock pulse. "The data must be stable 10ns before you clock the latch." :clocks: n. Processor logic cycles, so called because each generally corresponds to one clock pulse in the processor's timing. The relative execution times of instructions on a machine are usually discussed in clocks rather than absolute fractions of a second; one good reason for this is that clock speeds for various models of the machine may increase as technology improves, and it is usually the relative times one is interested in when discussing the instruction set. Compare {cycle}, {jiffy}. :clone: n. 1. An exact duplicate: "Our product is a clone of their product." Implies a legal reimplementation from documentation or by reverse-engineering. Also connotes lower price. 2. A shoddy, spurious copy: "Their product is a clone of our product." 3. A blatant ripoff, most likely violating copyright, patent, or trade secret protections: "Your product is a clone of my product." This use implies legal action is pending. 4. [obs] PC clone: a PC-BUS/ISA/EISA/PCI-compatible 80x86-based microcomputer (this use is sometimes spelled klone or PClone). These invariably have much more bang for the buck than the IBM archetypes they resemble. This term fell out of use in the 1990s; the class of machines it describes are now simply PCs or Intel machines. 5. [obs.] In the construction Unix clone: An OS designed to deliver a Unix-lookalike environment without Unix license fees, or with additional `mission-critical' features such as support for real-time programming. {Linux} and the free BSDs killed off this product category and the term with it. 6. v. To make an exact copy of something. "Let me clone that" might mean "I want to borrow that paper so I can make a photocopy" or "Let me get a copy of that file before you {mung} it". :clone-and-hack coding: n. [DEC] Syn. {case and paste}. :clover key: n. [Mac users] See {feature key}. :clue-by-four: [Usenet: portmanteau, clue + two-by-four] The notional stick with which one whacks an aggressively clueless person. This term derives from a western American folk saying about training a mule "First, you got to hit him with a two-by-four. That's to get his attention." The clue-by-four is a close relative of the {LART}. Syn. clue stick. This metaphor is commonly elaborated; your editor once heard a hacker say "I smite you with the great sword Cluebringer!" :clustergeeking: /kluh´st@r·gee`king/, n. [CMU] Spending more time at a computer cluster doing CS homework than most people spend breathing. :co-lo: /koh´loh`/, n. [very common; first heard c.1995] Short for `co-location', used of a machine you own that is physically sited on the premises of an ISP in order to take advantage of the ISP's direct access to lots of network bandwidth. Often in the phrases co-lo box or co-lo machines. Co-lo boxes are typically web and FTP servers remote-administered by their owners, who may seldom or never visit the actual site. :coaster: n. 1. Unuseable CD produced during failed attempt at writing to writeable or re-writeable CD media. Certainly related to the coaster-like shape of a CD, and the relative value of these failures. "I made a lot of coasters before I got a good CD." 2. Useless CDs received in the mail from the likes of AOL, MSN, CI$, Prodigy, ad nauseam. In the U.K., beermat is often used in these senses. :coaster toaster: A writer for recordable CD-Rs, especially cheap IDE models that tend to produce a high proportion of {coaster}s. :COBOL: /koh´bol/, n. [COmmon Business-Oriented Language] (Synonymous with {evil}.) A weak, verbose, and flabby language used by {code grinder}s to do boring mindless things on {dinosaur} mainframes. Hackers believe that all COBOL programmers are {suit}s or {code grinder}s, and no self-respecting hacker will ever admit to having learned the language. Its very name is seldom uttered without ritual expressions of disgust or horror. One popular one is Edsger W. Dijkstra's famous observation that "The use of COBOL cripples the mind; its teaching should, therefore, be regarded as a criminal offense." (from Selected Writings on Computing: A Personal Perspective) See also {fear and loathing}, {software rot}. :COBOL fingers: /koh´bol fing´grz/, n. Reported from Sweden, a (hypothetical) disease one might get from coding in COBOL. The language requires code verbose beyond all reason (see {candygrammar}); thus it is alleged that programming too much in COBOL causes one's fingers to wear down to stubs by the endless typing. "I refuse to type in all that source code again; it would give me COBOL fingers!" :cobweb site: n. A World Wide Web Site that hasn't been updated so long it has figuratively grown cobwebs. :code: 1. n. The stuff that software writers write, either in source form or after translation by a compiler or assembler. Often used in opposition to "data", which is the stuff that code operates on. Among hackers this is a mass noun, as in "How much code does it take to do a {bubble sort}?", or "The code is loaded at the high end of RAM." Among scientific programmers it is sometimes a count noun equilvalent to "program"; thus they may speak of "codes" in the plural. Anyone referring to software as "the software codes" is probably a {newbie} or a {suit}. 2. v. To write code. In this sense, always refers to source code rather than compiled. "I coded an Emacs clone in two hours!" This verb is a bit of a cultural marker associated with the Unix and minicomputer traditions (and lately Linux); people within that culture prefer v. `code' to v. `program' whereas outside it the reverse is normally true. :code grinder: n. 1. A {suit}-wearing minion of the sort hired in legion strength by banks and insurance companies to implement payroll packages in RPG and other such unspeakable horrors. In its native habitat, the code grinder often removes the suit jacket to reveal an underplumage consisting of button-down shirt (starch optional) and a tie. In times of dire stress, the sleeves (if long) may be rolled up and the tie loosened about half an inch. It seldom helps. The {code grinder}'s milieu is about as far from hackerdom as one can get and still touch a computer; the term connotes pity. See {Real World}, {suit}. 2. Used of or to a hacker, a really serious slur on the person's creative ability; connotes a design style characterized by primitive technique, rule-boundedness, {brute force}, and utter lack of imagination. Contrast {hacker}, {Real Programmer}. :code monkey: n 1. A person only capable of grinding out code, but unable to perform the higher-primate tasks of software architecture, analysis, and design. Mildly insulting. Often applied to the most junior people on a programming team. 2. Anyone who writes code for a living; a programmer. 3. A self-deprecating way of denying responsibility for a {management} decision, or of complaining about having to live with such decisions. As in "Don't ask me why we need to write a compiler in COBOL, I'm just a code monkey." :Code of the Geeks: n. see {geek code}. :code police: n. [by analogy with George Orwell's `thought police'] A mythical team of Gestapo-like storm troopers that might burst into one's office and arrest one for violating programming style rules. May be used either seriously, to underline a claim that a particular style violation is dangerous, or ironically, to suggest that the practice under discussion is condemned mainly by anal-retentive {weenie}s. "Dike out that goto or the code police will get you!" The ironic usage is perhaps more common. :codes: n. [scientific computing] Programs. This usage is common in people who hack supercomputers and heavy-duty {number-crunching}, rare to unknown elsewhere (if you say "codes" to hackers outside scientific computing, their first association is likely to be "and cyphers"). :codewalker: n. A program component that traverses other programs for a living. Compilers have codewalkers in their front ends; so do cross-reference generators and some database front ends. Other utility programs that try to do too much with source code may turn into codewalkers. As in "This new vgrind feature would require a codewalker to implement." :coefficient of X: n. Hackish speech makes heavy use of pseudo-mathematical metaphors. Four particularly important ones involve the terms coefficient, factor, index of X, and quotient. They are often loosely applied to things you cannot really be quantitative about, but there are subtle distinctions among them that convey information about the way the speaker mentally models whatever he or she is describing. Foo factor and foo quotient tend to describe something for which the issue is one of presence or absence. The canonical example is {fudge factor}. It's not important how much you're fudging; the term simply acknowledges that some fudging is needed. You might talk of liking a movie for its silliness factor. Quotient tends to imply that the property is a ratio of two opposing factors: "I would have won except for my luck quotient." This could also be "I would have won except for the luck factor", but using quotient emphasizes that it was bad luck overpowering good luck (or someone else's good luck overpowering your own). Foo index and coefficient of foo both tend to imply that foo is, if not strictly measurable, at least something that can be larger or smaller. Thus, you might refer to a paper or person as having a high bogosity index, whereas you would be less likely to speak of a high bogosity factor. Foo index suggests that foo is a condensation of many quantities, as in the mundane cost-of-living index; coefficient of foo suggests that foo is a fundamental quantity, as in a coefficient of friction. The choice between these terms is often one of personal preference; e.g., some people might feel that bogosity is a fundamental attribute and thus say coefficient of bogosity, whereas others might feel it is a combination of factors and thus say bogosity index. :cokebottle: /kohk´bot·l/, n. Any very unusual character, particularly one you can't type because it isn't on your keyboard. MIT people used to complain about the `control-meta-cokebottle' commands at SAIL, and SAIL people complained right back about the `escape-escape-cokebottle' commands at MIT. After the demise of the {space-cadet keyboard}, cokebottle faded away as serious usage, but was often invoked humorously to describe an (unspecified) weird or non-intuitive keystroke command. It may be due for a second inning, however. The OSF/Motif window manager, mwm(1), has a reserved keystroke for switching to the default set of keybindings and behavior. This keystroke is (believe it or not) `control-meta-bang' (see {bang}). Since the exclamation point looks a lot like an upside down Coke bottle, Motif hackers have begun referring to this keystroke as cokebottle. See also {quadruple bucky}. :cold boot: n. See {boot}. :COME FROM: n. A semi-mythical language construct dual to the `go to'; COME FROM
