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 4.2.2" or "The on-line hacker Jargon File, version 4.2.2, 20 AUG 2000".) 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 [5]esr@snark.thyrsus.com 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 two `authorized' editions so far are described in the Revision History section; there may be more in the future. * [6]Introduction: The purpose and scope of this File * [7]A Few Terms: Of Slang, Jargon and Techspeak * [8]Revision History: How the File came to be * [9]Jargon Construction: How hackers invent jargon * [10]Hacker Writing Style: How they write * [11]Email Quotes: And the Inclusion Problem * [12]Hacker Speech Style: How hackers talk * [13]International Style: Some notes on usage outside the U.S. * [14]Lamer-speak: Crackers, Phreaks, and Lamers * [15]Pronunciation Guide: How to read the pronunciation keys * [16]Other Lexicon Conventions: How to read lexicon entries * [17]Format for New Entries: How to submit new entries for the File * [18]The Jargon Lexicon: The lexicon itself * [19]Appendix A: Hacker Folklore * [20]Appendix B: A Portrait of J.

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 40 years old. As usual with slang, the special vocabulary of hackers helps hold their culture together -- it helps hackers recognize each other's 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 [26]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 `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 [27]kluge and an [28]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. But there is more. 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, it has recently become 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 for over 15 years. 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 [29]Appendix A. The `outside' reader's attention is particularly directed to the Portrait of J. Random Hacker in [30]Appendix B. Appendix C, the [31]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. _________________________________________________________________ Node:A Few Terms, Next:[32]Revision History, Previous:[33]Introduction, Up:[34]Top 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 [35]Jargon Construction section below). In general, we have considered techspeak any term that communicates 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 [36]kluge, [37]cruft, and [38]foo. We believe specialist lexicographers will find many of the historical notes more than casually instructive. _________________________________________________________________ Node:Revision History, Next:[39]Jargon Construction, Previous:[40]A Few Terms, Up:[41]Top 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 ([42]frob and some senses of [43]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, [44]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 [45]TWENEX system rather than a host for the AI hackers' beloved [46]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 [47]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 [48]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 [49]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 [50] maintains the new File with assistance from Guy L. Steele Jr. [51]; 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.

The 2.9.6 version became the main text of "The New Hacker's Dictionary", by Eric Raymond (ed.), MIT Press 1991, ISBN 0-262-68069-6. The 3.0.0 version was published in September 1993 as the second edition of "The New Hacker's Dictionary", again from MIT Press (ISBN 0-262-18154-1). If you want the book, you should be able to find it at any of the major bookstore chains. Failing that, you can order by mail from The MIT Press 55 Hayward Street Cambridge, MA 02142 or order by phone at (800)-356-0343 or (617)-625-8481. The maintainers are committed to updating the on-line version of the Jargon File through and beyond paper publication, and will continue to make it available to archives and public-access sites as a trust of the hacker community.

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 [53], Bernie Cosell [54], Earl Boebert [55], and Joe Morris [56]. We were fortunate enough to have the aid of some accomplished linguists. David Stampe [57] and Charles Hoequist [58] contributed valuable criticism; Joe Keane [59] helped us improve the pronunciation guides. A few bits of this text quote previous works. We are indebted to Brian A. LaMacchia [60] for obtaining permission for us to use material from the "TMRC Dictionary"; also, Don Libes [61] contributed some appropriate material from his excellent book "Life With UNIX". We thank Per Lindberg [62], 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 [63] 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 [64] and Steve Summit [65] 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 several years and several different editions has only allowed him to escape co-editor credit by the slimmest of margins. Finally, George V. Reilly [66] helped with TeX arcana and painstakingly proofread some 2.7 and 2.8 versions, and Eric Tiedemann [67] contributed sage advice throughout on rhetoric, amphigory, and philosophunculism. _________________________________________________________________ Node:Jargon Construction, Next:[68]Hacker Writing Style, Previous:[69]Revision History, Up:[70]Top How Jargon Works Jargon Construction 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. * [71]Verb Doubling: Doubling a verb may change its semantics * [72]Soundalike Slang: Punning jargon * [73]The -P convention: A LISPy way to form questions * [74]Overgeneralization: Standard abuses of grammar * [75]Spoken Inarticulations: Sighing and <*sigh*>ing * [76]Anthropomorphization: Homunculi, daemons, and confused programs * [77]Comparatives: Standard comparatives for design quality _________________________________________________________________ Node:Verb Doubling, Next:[78]Soundalike Slang, Up:[79]Jargon Construction 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 [80]win, [81]lose, [82]hack, [83]flame, [84]barf, [85]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 [86]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 _________________________________________________________________ Node:Soundalike Slang, Next:[87]The -P convention, Previous:[88]Verb Doubling, Up:[89]Jargon Construction 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 [90]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 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. _________________________________________________________________ Node:The -P convention, Next:[91]Overgeneralization, Previous:[92]Soundalike Slang, Up:[93]Jargon Construction 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 [94]T and [95]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?'' [One of the best of these is a [96]Gosperism. 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] _________________________________________________________________ Node:Overgeneralization, Next:[97]Spoken Inarticulations, Previous:[98]The -P convention, Up:[99]Jargon Construction 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 [100]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 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 [101]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 [102]VAXen and [103]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 `frobbotzim' for the plural of `frobbozz' (see [104]frobnitz) and `Unices' and `Twenices' (rather than `Unixes' and `Twenexes'; see [105]Unix, [106]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. 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. _________________________________________________________________ Node:Spoken Inarticulations, Next:[107]Anthropomorphization, Previous:[108]Overgeneralization, Up:[109]Jargon Construction 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!" _________________________________________________________________ Node:Anthropomorphization, Next:[110]Comparatives, Previous:[111]Spoken Inarticulations, Up:[112]Jargon Construction 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". 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 seemds to ascribe conciousness 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 a that a human machine can have intentions, it is therefore easy for them to ascribe consciousness and intention to 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 truth but of utility. Hackers typically view simple programs from the design stance, but more complex ones are modelled using the intentional stance. _________________________________________________________________ Node:Comparatives, Previous:[113]Anthropomorphization, Up:[114]Jargon Construction 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 [115]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. _________________________________________________________________ Node:Hacker Writing Style, Next:[116]Email Quotes, Previous:[117]Jargon Construction, Up:[118]Top 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 [119]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 Latin languages (including Spanish, French, Italian, Catalan) 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 [120]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 [121]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 [122]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 [123]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 [124]random member of a larger class (this is straight from [125]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). This convention 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 tale on new life on IRCs and other line-based chat systems. I've seen that term used on alt.foobar often. Send it to Erik for the File. 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). 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 seconds long. The tilde (~) is commonly used in a quantifying sense of `approximately'; that is, ~50 means `about fifty'. On Usenet and in the [126]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: >I recently had occasion to field-test the Snafu >Systems 2300E adaptive gonkulator. The price was >right, and the racing stripe on the case looked >kind of neat, but its performance left something >to be desired. Yeah, I tried one out too. #ifdef FLAME Hasn't anyone told those idiots that you can't get decent bogon suppression with AFJ filters at today's net volumes? #endif /* FLAME */ I guess they figured the price premium for true frame-based semantic analysis was too high. Unfortunately, it's also the only workable approach. I wouldn't recommend purchase of this product unless you're on a *very* tight budget. #include -- == 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 [127]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 father was a hamster and your mother smelt of elderberries! You'll even see this with an HTML-style modifier: You seem well-suited for a career in government. Another recent (late 1990s) construction now common on USENET seems to be borrowed from Perl. It consists of using a dollar sign before an uppercased form of a word or acronym to suggest any [128]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. _________________________________________________________________ Node:Email Quotes, Next:[129]Hacker Speech Style, Previous:[130]Hacker Writing Style, Up:[131]Top 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. Because the default mailers supplied with Unix and other operating systems haven't evolved as quickly as human usage, the older conventions using a leading TAB or three or four spaces are still alive; however, >-inclusion is now clearly the prevalent form in both netnews and mail. Inclusion practice is still evolving, and disputes over the `correct' inclusion style occasionally lead to [132]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, 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). _________________________________________________________________ Node:Hacker Speech Style, Next:[133]International Style, Previous:[134]Email Quotes, Up:[135]Top 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 [136]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!"). _________________________________________________________________ Node:International Style, Next:[137]Lamer-speak, Previous:[138]Hacker Speech Style, Up:[139]Top 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 [140]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, core-gedumpt. And Spanish-speaking hackers use `linkar' (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. _________________________________________________________________ Node:Lamer-speak, Next:[141]Pronunciation Guide, Previous:[142]International Style, Up:[143]Top 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 [144]crackers, phone phreaks, and [145]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. 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. Nevertheless, this lexicon covers much of it so the reader will be able to understand what goes by on bulletin-board systems. Here is a brief guide to cracker and [146]warez d00dz usage: * Misspell frequently. The substitutions phone => fone 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 bow 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"). * Substitute `0' for `o' ("r0dent", "l0zer"). * TYPE ALL IN CAPS LOCK, SO IT LOOKS LIKE YOU'RE YELLING ALL THE TIME. These traits are similar to those of [147]B1FF, who originated as a parody of naive [148]BBS users; also of his latter-day equivalent [149]Jeff K.. Occasionally, this sort of distortion may be used as heavy sarcasm by a real hacker, as in: > I got X Windows running under Linux! d00d! u R an 31337 hax0r The only practice resembling this in actual 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 [150]lamer, [151]elite, [152]leech, [153]poser, [154]cracker, and especially [155]warez d00dz, [156]banner site, [157]ratio site, [158]leech mode. _________________________________________________________________ Node:Pronunciation Guide, Next:[159]Other Lexicon Conventions, Previous:[160]Lamer-speak, Up:[161]Top How to Use the Lexicon 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: 1. 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). 2. 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). 3. 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. 4. Vowels are represented as follows: /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 one that is often written with an upside-down `e'). 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'!) _________________________________________________________________ Node:Other Lexicon Conventions, Next:[162]Format for New Entries, Previous:[163]Pronunciation Guide, Up:[164]Top 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 after Z. The case-blindness is a feature, not a bug. The beginning of each entry is marked by a colon (:) at the left margin. This convention helps out tools like hypertext browsers that benefit from knowing where entry boundaries are, but aren't as context-sensitive as humans. In pure ASCII renderings of the Jargon File, you will see {} used to bracket words which themselves have entries in the File. This isn't done all the time for every such word, but it is done everywhere that a reminder seems useful that the term has a jargon meaning and one might wish to refer to its entry. In this all-ASCII version, headwords for topic entries are distinguished from those for ordinary entries by being followed by "::" rather than ":"; similarly, references are surrounded by "{{" and "}}" rather than "{" and "}". Defining instances of terms and phrases appear in `slanted type'. A defining instance is one which occurs near to or as part of an explanation of it. Prefixed ** 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 freeware 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: 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: 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!)

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 [166]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 Some other etymology abbreviations such as [167]Unix and [168]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. _________________________________________________________________ Node:Format for New Entries, Next:[169]The Jargon Lexicon, Previous:[170]Other Lexicon Conventions, Up:[171]Top Format For New Entries You can mail submissions for the Jargon File to [172]jargon@snark.thyrsus.com.

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 Ř 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? _________________________________________________________________ Node:1TBS, Next:[215]120 reset, Previous:[216]0, Up:[217]= 0 = 1TBS // n.

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).

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.

Without a prefix, this almost invariably refers to [238]BSD Unix release 4.2. Note that it is an indication of cluelessness to say "version 4.2", and "release 4.2" is rare; the number stands on its own, or is used in the more explicit forms 4.2BSD or (less commonly) BSD 4.2. Similar remarks apply to "4.3", "4.4" and to earlier, less-widespread releases 4.1 and 2.9. _________________________________________________________________ Node:@-party, Next:[239]abbrev, Previous:[240]4.2, Up:[241]= 0 = @-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 [242]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 [243]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. _________________________________________________________________ Node:= A =, Next:[244]= B =, Previous:[245]= 0 =, Up:[246]The Jargon Lexicon = A = * [247]abbrev: * [248]ABEND: * [249]accumulator: * [250]ACK: * [251]Acme: * [252]acolyte: * [253]ad-hockery: * [254]Ada: * [255]address harvester: * [256]adger: * [257]admin: * [258]ADVENT: * [259]AFAIK: * [260]AFJ: * [261]AFK: * [262]AI: * [263]AI-complete: * [264]AI koans: * [265]AIDS: * [266]AIDX: * [267]airplane rule: * [268]Alderson loop: * [269]aliasing bug: * [270]Alice and Bob: * [271]all-elbows: * [272]alpha geek: * [273]alpha particles: * [274]alt: * [275]alt bit: * [276]Aluminum Book: * [277]ambimouseterous: * [278]Amiga: * [279]Amiga Persecution Complex: * [280]amoeba: * [281]amp off: * [282]amper: * [283]Angband: * [284]angle brackets: * [285]angry fruit salad: * [286]annoybot: * [287]annoyware: * [288]ANSI: * [289]ANSI standard: * [290]ANSI standard pizza: * [291]AOL!: * [292]app: * [293]arena: * [294]arg: * [295]ARMM: * [296]armor-plated: * [297]asbestos: * [298]asbestos cork award: * [299]asbestos longjohns: * [300]ASCII: * [301]ASCII art: * [302]ASCIIbetical order: * [303]astroturfing: * [304]atomic: * [305]attoparsec: * [306]AUP: * [307]autobogotiphobia: * [308]automagically: * [309]avatar: * [310]awk: _________________________________________________________________ Node:abbrev, Next:[311]ABEND, Previous:[312]@-party, Up:[313]= A = abbrev /*-breev'/, /*-brev'/ n.

[ABnormal END] 1. Abnormal termination (of software); [317]crash; [318]lossage. Derives from an error message on the IBM 360; used jokingly by hackers but seriously mainly by [319]code grinders. 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. _________________________________________________________________ Node:accumulator, Next:[320]ACK, Previous:[321]ABEND, Up:[322]= A = 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 [323]stack.) _________________________________________________________________ Node:ACK, Next:[324]Acme, Previous:[325]accumulator, Up:[326]= A = 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 [327]ping or [328]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 [329]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 [330]talk mode to see if the person has gone away (the standard humorous response is of course [331]NAK (sense 1), i.e., "I'm not here"). _________________________________________________________________ Node:Acme, Next:[332]acolyte, Previous:[333]ACK, Up:[334]= A = Acme n. 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 [335]insanely great", or, more likely, "This looks [336]insanely great on paper, but in practice it's really easy to shoot yourself in the foot with it." Compare [337]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 "Roadrunner" cartoons. In these cartoons, the famished Wile E. Coyote was forever attempting to catch up with, trap, and eat the Roadrunner. 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 cardboard boxes, labeled prominently with the Acme name. These devices invariably malfunctioned in improbable and violent ways. _________________________________________________________________ Node:acolyte, Next:[338]ad-hockery, Previous:[339]Acme, Up:[340]= A = acolyte n. obs.

[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 [346]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'.

A [351]Pascal-descended language that was at one time made mandatory for Department of Defense software projects by the Pentagon. Hackers are nearly unanimous in observing that, technically, it is precisely what one might expect given that kind of endorsement by fiat; designed by committee, crockish, difficult to use, and overall a disastrous, multi-billion-dollar boondoggle (one common description wss "The PL/I of the 1980s"). Hackers find Ada's exception-handling and inter-process communication features particularly hilarious. Ada Lovelace (the daughter of Lord Byron who became the world's first programmer while cooperating with Charles Babbage on the design of his mechanical computing engines in the mid-1800s) would almost certainly blanch at the use to which her name has latterly been put; the kindest thing that has been said about it is that there is probably a good small language screaming to get out from inside its vast, [352]elephantine bulk. _________________________________________________________________ Node:address harvester, Next:[353]adger, Previous:[354]Ada, Up:[355]= A = address harvester 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).

The prototypical computer adventure game, first designed by Will Crowther on the [373]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 [374]INTERCAL.) Now better known as Adventure or Colossal Cave Adventure, but the [375]TOPS-10 operating system permitted only six-letter filenames. See also [376]vadding, [377]Zork, and [378]Infocom. 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' [379]xyzzy and [380]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.

[MIT, Stanford: by analogy with `NP-complete' (see [399]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 (1999) to solve them have foundered on the amount of context information and `intelligence' they seem to require.

Derogatory term for IBM's perverted version of Unix, AIX, especially for the AIX 3.? used in the IBM RS/6000 series (some hackers think it is funnier just to pronounce "AIX" as "aches"). A victim of the dreaded "hybridism" disease, this attempt to combine the two main currents of the Unix stream ([420]BSD and [421]USG Unix) became a [422]monstrosity to haunt system administrators' dreams. For example, if new accounts are created while many users are logged on, the load average jumps quickly over 20 due to silly implementation of the user databases. For a quite similar disease, compare [423]HP-SUX. Also, compare [424]Macintrash, [425]Nominal Semidestructor, [426]ScumOS, [427]sun-stools. _________________________________________________________________ Node:airplane rule, Next:[428]Alderson loop, Previous:[429]AIDX, Up:[430]= A = 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.

[Intel] A special version of an [436]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. _________________________________________________________________ Node:aliasing bug, Next:[437]Alice and Bob, Previous:[438]Alderson loop, Up:[439]= A = 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 (`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 [440]arena. Avoidable by use of allocation strategies that never alias allocated core, or by use of higher-level languages, such as [441]LISP, which employ a garbage collector (see [442]GC). Also called a [443]stale pointer bug. See also [444]precedence lossage, [445]smash the stack, [446]fandango on core, [447]memory leak, [448]memory smash, [449]overrun screw, [450]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. _________________________________________________________________ Node:Alice and Bob, Next:[451]all-elbows, Previous:[452]aliasing bug, Up:[453]= A = 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 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, So 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 [454]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 introduces 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. _________________________________________________________________ Node:all-elbows, Next:[455]alpha geek, Previous:[456]Alice and Bob, Up:[457]= A = all-elbows adj.

The `option' key on a Macintosh; use of this term usually reveals that the speaker hacked PCs before coming to the Mac (see also [473]feature key, which is sometimes incorrectly called `alt'). 3. n.,obs. [PDP-10; often capitalized to ALT] Alternate name for the ASCII ESC character (ASCII 0011011), after the keycap labeling on some older terminals; also `altmode' (/awlt'mohd/). This character was almost never pronounced `escape' on an ITS system, in [474]TECO, or under TOPS-10 -- always alt, as in "Type alt alt to end a TECO command" or "alt-U onto the system" (for "log onto the [ITS] system"). This usage probably arose because alt is more convenient to say than `escape', especially when followed by another alt or a character (or another alt and a character, for that matter). 4. 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". _________________________________________________________________ Node:alt bit, Next:[475]Aluminum Book, Previous:[476]alt, Up:[477]= A = alt bit /awlt bit/ [from alternate] adj.

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 [489]Amiga Persecution Complex). The traits of this culture are both spoofed and illuminated in [490]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 [491]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. _________________________________________________________________ Node:Amiga Persecution Complex, Next:[492]amoeba, Previous:[493]Amiga, Up:[494]= A = Amiga Persecution Complex n.

The name is from Tolkien's Pits of Angband (compare [524]elder days, [525]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).

A type of [546]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.

ANSI, along with the International Organization for Standards (ISO), standardized the C programming language (see [559]K&R, [560]Classic C), and promulgates many other important software standards. 2. n. [techspeak] A terminal may be said to be `ANSI' if it meets the ANSI X.364 standard for terminal control. Unfortunately, this standard was both over-complicated and too permissive. It has been retired and replaced by the ECMA-48 standard, which shares both flaws. 3. n. [BBS jargon] The set of screen-painting codes that most MS-DOS and Amiga computers accept. This comes from the ANSI.SYS device driver that must be loaded on an MS-DOS computer to view such codes. Unfortunately, neither DOS ANSI nor the BBS ANSIs derived from it exactly match the ANSI X.364 terminal standard. For example, the ESC-[1m code turns on the bold highlight on large machines, but in IBM PC/MS-DOS ANSI, it turns on `intense' (bright) colors. Also, in BBS-land, the term `ANSI' is often used to imply that a particular computer uses or can emulate the IBM high-half character set from MS-DOS. Particular use depends on context. Occasionally, the vanilla ASCII character set is used with the color codes, but on BBSs, ANSI and `IBM characters' tend to go together. _________________________________________________________________ Node:ANSI standard, Next:[561]ANSI standard pizza, Previous:[562]ANSI, Up:[563]= A = ANSI standard /an'see stan'd*rd/ The ANSI standard usage of `ANSI standard' refers to any practice which is typical or broadly done.

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.)

Compare [590]param, [591]parm, [592]var. _________________________________________________________________ Node:ARMM, Next:[593]armor-plated, Previous:[594]arg, Up:[595]= A = ARMM n. [acronym, `Automated Retroactive Minimal Moderation'] A Usenet [596]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 31, 1993 and proceeded to [597]spam news.admin.policy with a recursive explosion of over 200 messages. ARMM's bug produced a recursive [598]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 [599]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.

[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 of ASCII prior to June 1961) used fewer. This change allowed the inclusion of lowercase letters -- a major [629]win -- but it did not provide for accented letters or any other letterforms not used in English (such as the German sharp-S or the ae-ligature which is a letter in, for example, Norwegian). It could be worse, though. It could be much worse. See [630]EBCDIC to understand how. A history of ASCII and its ancestors is at [631]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 [632]bang, [633]excl, [634]open, [635]ques, [636]semi, [637]shriek, [638]splat, [639]twiddle, and [640]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.

The pronunciation of # as `pound' is common in the U.S. but a bad idea; [650]Commonwealth Hackish has its own, rather more apposite use of `pound sign' (confusingly, on British keyboards the pound graphic 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 [651]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 is not quite the same as tilde in typeset material but the ASCII tilde serves for both (compare [652]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 [653]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 [654]misfeature as the use of international networks continues to increase (see [655]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. _________________________________________________________________ Node:ASCII art, Next:[656]ASCIIbetical order, Previous:[657]ASCII, Up:[658]= A = ASCII art n.

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. This backfired horribly, angering a number of state attorneys-general enough to induce them to go public with plans to join the Federal suit.

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.

[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. [926]trap door; may also be called a `wormhole'. See also [927]iron box, [928]cracker, [929]worm, [930]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 talk that suggested this truly moby hack was published as "Reflections on Trusting Trust", "Communications of the ACM 27", 8 (August 1984), pp. 761-763 (text available at [931]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'. _________________________________________________________________ Node:backbone cabal, Next:[932]backbone site, Previous:[933]back door, Up:[934]= B = backbone cabal n. A group of large-site administrators who pushed through the [935]Great Renaming and reined in the chaos of [936]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 [937]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 [938]Eric Conspiracy for one example.

"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 [956]amp off, [957]slopsucker. Technically, a task running in background is detached from the terminal where it was started (and often running at a lower priority); oppose [958]foreground.

[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 [977]software bloat.

[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, Bad and Wrong" (abbreviated EBW) is reported fromm 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".

British correspondents confirm that [994]Bad Thing and [995]Good Thing (and prob. therefore [996]Right Thing and [997]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 here.

[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 ...."

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: [1005]loser, [1006]cretin, [1007]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.

[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 (see examples below). 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; 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 backedup 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." _________________________________________________________________ Node:balloonian variable, Next:[1021]bamf, Previous:[1022]baggy pantsing, Up:[1023]= B = 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.

[1029]MUD) electronic [1030]fora when a character wishes to make a dramatic entrance or exit. 2. The sound of magical transformation, used in virtual reality [1031]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 [1032]http://www.tuxedo.org/jargon/".) _________________________________________________________________ Node:banana label, Next:[1033]banana problem, Previous:[1034]bamf, Up:[1035]= B = banana label n.

See item 176 under [1043]HAKMEM, which describes a banana problem in a [1044]Dissociated Press implementation.

"Those are amazing graphics, but I missed some of the detail -- not enough bandwidth, I guess." Compare [1053]low-bandwidth. This generalized usage began to go mainstream after the Internet population explosion of 1993-1994. 2. Attention span. 3.

Common spoken name for ! (ASCII 0100001), especially when used in pronouncing a [1058]bang path in spoken hackish. In [1059]elder days this was considered a CMUish usage, with MIT and Stanford hackers preferring [1060]excl or [1061]shriek; but the spread of Unix has carried `bang' with it (esp. via the term [1062]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 [1063]shriek, [1064]ASCII. 2. interj. An exclamation signifying roughly "I have achieved enlightenment!", or "The dynamite has cleared out my brain!"

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 [1069]pound on is synonymous. _________________________________________________________________ Node:bang path, Next:[1070]banner, Previous:[1071]bang on, Up:[1072]= B = 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 [1073]hop is signified by a [1074]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 [1075]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 in 1981. 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 [1076]Internet address, [1077]the network, and [1078]sitename. _________________________________________________________________ Node:banner, Next:[1079]banner ad, Previous:[1080]bang path, Up:[1081]= B = banner n. 1. The title page added to printouts by most print spoolers (see [1082]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. 2. 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}). 3. On interactive software, a first screen containing a logo and/or author credits and/or a copyright notice. This is probably now the commonest sense. _________________________________________________________________ Node:banner ad, Next:[1083]banner site, Previous:[1084]banner, Up:[1085]= B = banner ad n.

[warez d00dz] A 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.

[very common] The second [1094]metasyntactic variable, after [1095]foo and before [1096]baz. "Suppose we have two functions: FOO and BAR. FOO calls BAR...." 2. Often appended to [1097]foo to produce [1098]foobar. _________________________________________________________________ Node:bare metal, Next:[1099]barf, Previous:[1100]bar, Up:[1101]= B = bare metal n. 1. [common] New computer hardware, unadorned with such snares and delusions as an [1102]operating system, an [1103]HLL, or even assembler. Commonly used in the phrase `programming on the bare metal', which refers to the arduous work of [1104]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 [1105]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 [1106]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 less common 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, and in the code of hackers who just can't let go of that low-level control. See [1107]Real Programmer. In the world of personal computing, bare metal programming (especially in sense 1 but sometimes also in sense 2) is often considered a [1108]Good Thing, or at least a necessary evil (because these machines have often been sufficiently slow and poorly designed to make it necessary; see [1109]ill-behaved). There, the term usually refers to bypassing the BIOS or OS interface and writing the application to directly access device registers and machine addresses. "To get 19.2 kilobaud on the serial port, you need to get down to the bare metal." People who can do this sort of thing well are held in high regard. _________________________________________________________________ Node:barf, Next:[1110]barfmail, Previous:[1111]bare metal, Up:[1112]= B = 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 [1113]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 [1114]choke, [1115]gag. In Commonwealth Hackish, `barf' is generally replaced by `puke' or `vom'. [1116]barf is sometimes also used as a [1117]metasyntactic variable, like [1118]foo or [1119]bar. _________________________________________________________________ Node:barfmail, Next:[1120]barfulation, Previous:[1121]barf, Up:[1122]= B = barfmail 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 cm^2) and the book containing cross-sections has a picture of a barn on the cover. _________________________________________________________________ Node:barney, Next:[1134]baroque, Previous:[1135]barn, Up:[1136]= B = barney n. In Commonwealth hackish, `barney' is to [1137]fred (sense #1) as [1138]bar is to [1139]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. _________________________________________________________________ Node:baroque, Next:[1140]BASIC, Previous:[1141]barney, Up:[1142]= B = baroque adj. [common] Feature-encrusted; complex; gaudy; verging on excessive. Said of hardware or (esp.) software designs, this has many of the connotations of [1143]elephantine or [1144]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 [1145]rococo. _________________________________________________________________ Node:BASIC, Next:[1146]batbelt, Previous:[1147]baroque, Up:[1148]= B = 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 [1149]Pascal) of the cascading [1150]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] Note: the name is commonly parsed as Beginner's All-purpose Symbolic Instruction Code, but this is a [1151]backronym. BASIC was originally named Basic, simply because it was a simple and basic programming language. Because most programming language names were in fact acronyms, BASIC was often capitalized just out of habit or to be silly. No acronym for BASIC originally existed or was intended (as one can verify by reading texts through the early 1970s). Later, around the mid-1970s, people began to make up backronyms for BASIC because they weren't sure. Beginner's All-purpose Symbolic Instruction Code is the one that caught on. _________________________________________________________________ Node:batbelt, Next:[1152]batch, Previous:[1153]BASIC, Up:[1154]= B = 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. _________________________________________________________________ Node:batch, Next:[1155]bathtub curve, Previous:[1156]batbelt, Up:[1157]= B = 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." _________________________________________________________________ Node:bathtub curve, Next:[1158]baud, Previous:[1159]batch, Up:[1160]= B = 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 [1161]burn-in period, [1162]infant mortality. _________________________________________________________________ Node:baud, Next:[1163]baud barf, Previous:[1164]bathtub curve, Up:[1165]= B = 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. _________________________________________________________________ Node:baud barf, Next:[1166]baz, Previous:[1167]baud, Up:[1168]= B = baud barf /bawd barf/ n. The garbage one gets a terminal (or terminal emulator) when using a modem connection with some protocol setting (esp. line speed) incorrect, or when someone picks up a voice extension on the same line, or when really bad line noise disrupts the connection. Baud barf is not completely [1169]random, by the way; hackers with a lot of serial-line experience can usually tell whether the device at the other end is expecting a higher or lower speed than the terminal is set to. Really experienced ones can identify particular speeds. _________________________________________________________________ Node:baz, Next:[1170]bazaar, Previous:[1171]baud barf, Up:[1172]= B = baz /baz/ n. 1. [common] The third [1173]metasyntactic variable "Suppose we have three functions: FOO, BAR, and BAZ. FOO calls BAR, which calls BAZ...." (See also [1174]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 [1175]foo to produce `foobaz'. Earlier versions of this lexicon derived `baz' as a Stanford corruption of [1176]bar. However, Pete Samson (compiler of the [1177]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)." _________________________________________________________________ Node:bazaar, Next:[1178]bboard, Previous:[1179]baz, Up:[1180]= B = bazaar n.,adj. In 1997, after meditatating on the success of [1181]Linux for three years, the Jargon File's own editor ESR wrote an analytical paper on hacker culture and development models titled [1182]The Cathedral and the Bazaar. The main argument of the paper was that [1183]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 [1184]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. _________________________________________________________________ Node:bboard, Next:[1185]BBS, Previous:[1186]bazaar, Up:[1187]= B = bboard /bee'bord/ n. [contraction of `bulletin board'] 1. Any electronic bulletin board; esp. used of [1188]BBS systems running on personal micros, less frequently of a Usenet [1189]newsgroup (in fact, use of this term for a newsgroup generally marks one either as a [1190]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". _________________________________________________________________ Node:BBS, Next:[1191]BCPL, Previous:[1192]bboard, Up:[1193]= B = 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 [1194]topic groups. 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.

[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 [1199]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. _________________________________________________________________ Node:beam, Next:[1200]beanie key, Previous:[1201]BCPL, Up:[1202]= B = beam vt.

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).

Distinguished from [1231]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. _________________________________________________________________ Node:bells whistles and gongs, Next:[1232]benchmark, Previous:[1233]bells and whistles, Up:[1234]= B = bells whistles and gongs n.

(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 [1247]Berzerkeley.

Mostly working, but still under test; usu. used with `in': `in beta'. In the [1263]Real World, systems (hardware or software) software 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. _________________________________________________________________ Node:BFI, Next:[1264]bible, Previous:[1265]beta, Up:[1266]= B = BFI /B-F-I/ n.

My spies inform me that B1FF was originally created by Joe Talmadge , also the author of the infamous and much-plagiarized "Flamer's Bible".

Sources at IBM report that, in tune with the company's passion for [1315]TLAs, this is often abbreviated as `BRS' (this has also become established on FidoNet and in the PC [1316]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 [1317]molly-guard).

[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 [1332]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 [1333]little-endian, [1334]middle-endian, [1335]NUXI problem, [1336]swab. 2. An [1337]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 Networking Team had decided to do it the other way round before the Internet domain standard was established. Most gateway sites have [1338]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. _________________________________________________________________ Node:bignum, Next:[1339]bigot, Previous:[1340]big-endian, Up:[1341]= B = 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 [1342]moby, sense 4). See also [1343]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) or (on a [1344]bitty box) 2^(15) (32,768). 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 000000000000000000. _________________________________________________________________ Node:bigot, Next:[1345]bit, Previous:[1346]bignum, Up:[1347]= B = bigot n.

"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 [1354]toggle or `invert' a bit is to change it, either from 0 to 1 or from 1 to 0. See also [1355]flag, [1356]trit, [1357]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. _________________________________________________________________ Node:bit bang, Next:[1358]bit bashing, Previous:[1359]bit, Up:[1360]= B = bit bang n. Transmission of data on a serial line, when accomplished by rapidly tweaking a single output bit, in software, at the appropriate times. The technique is a simple loop with eight OUT and SHIFT instruction pairs for each byte. Input is more interesting. And full duplex (doing input and output at the same time) is one way to separate the real hackers from the [1361]wannabees. Bit bang was used on certain early models of Prime computers, presumably when UARTs were too expensive, and on archaic Z80 micros with a Zilog PIO but no SIO. In an interesting instance of the [1362]cycle of reincarnation, this technique returned to use in the early 1990s on some RISC architectures because it consumes such an infinitesimal part of the processor that it actually makes sense not to have a UART. Compare [1363]cycle of reincarnation. _________________________________________________________________ Node:bit bashing, Next:[1364]bit bucket, Previous:[1365]bit bang, Up:[1366]= B = bit bashing n. (alt. `bit diddling' or [1367]bit twiddling) Term used to describe any of several kinds of low-level programming characterized by manipulation of [1368]bit, [1369]flag, [1370]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 [1371]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 [1372]bit bang, [1373]mode bit. _________________________________________________________________ Node:bit bucket, Next:[1374]bit decay, Previous:[1375]bit bashing, Up:[1376]= B = 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 [1377]Unix, often used for [1378]/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 [1379]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 [1380]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 [1381]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. _________________________________________________________________ Node:bit decay, Next:[1382]bit rot, Previous:[1383]bit bucket, Up:[1384]= B = bit decay n.

[common] Also [1391]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 [1392]cosmic rays entry for details. The term [1393]software rot is almost synonymous. Software rot is the effect, bit rot the notional cause. _________________________________________________________________ Node:bit twiddling, Next:[1394]bit-paired keyboard, Previous:[1395]bit rot, Up:[1396]= B = bit twiddling n. [very common] 1. (pejorative) An exercise in tuning (see [1397]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 [1398]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. _________________________________________________________________ Node:bit-paired keyboard, Next:[1399]bitblt, Previous:[1400]bit twiddling, Up:[1401]= B = 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 [1402]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 [1403]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. _________________________________________________________________ Node:bitblt, Next:[1404]BITNET, Previous:[1405]bit-paired keyboard, Up:[1406]= B = bitblt /bit'blit/ n.

To use a navigator or off-line message reader to minimize time spent on-line to a commercial network service (a necessity in many places outside the U.S. where the telecoms monopolies charge per-minute for local calls). This term attained wide use in the UK, but is rare or unknown in the US. _________________________________________________________________ Node:blinkenlights, Next:[1512]blit, Previous:[1513]blink, Up:[1514]= B = blinkenlights /blink'*n-li:tz/ n. [common] Front-panel diagnostic lights on a computer, esp. a [1515]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! 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 1959 at Stanford University 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 [1516]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. 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 easy 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. _________________________________________________________________ Node:blit, Next:[1517]blitter, Previous:[1518]blinkenlights, Up:[1519]= B = blit /blit/ vt. 1.

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 [1535]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. _________________________________________________________________ Node:bloatware, Next:[1536]BLOB, Previous:[1537]blivet, Up:[1538]= B = bloatware n.

The usage lives on (it's too vivid and expressive to discard) even though the write process on EPROMs is nondestructive. _________________________________________________________________ Node:blow away, Next:[1560]blow out, Previous:[1561]blow an EPROM, Up:[1562]= B = blow away vt.

Synonym for [1583]blit. This is the original form of [1584]blit and the ancestor of [1585]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 [1586]PDP-10 BLock Transfer instruction from which [1587]BLT derives; nowadays, the assembler mnemonic [1588]BLT almost always means `Branch if Less Than zero'. _________________________________________________________________ Node:Blue Book, Next:[1589]blue box, Previous:[1590]BLT, Up:[1591]= B = Blue Book n. 1.

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 [1600]phreakers 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. 2. n.

The official IBM definition is "that which binds blue boxes together." See [1607]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 [1608]dinosaur pens. 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'. _________________________________________________________________ Node:blue goo, Next:[1609]Blue Screen of Death, Previous:[1610]Blue Glue, Up:[1611]= B = blue goo n. Term for `police' [1612]nanobots intended to prevent [1613]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 [1614]nanotechnology. _________________________________________________________________ Node:Blue Screen of Death, Next:[1615]blue wire, Previous:[1616]blue goo, Up:[1617]= B = Blue Screen of Death n. [common] This term is closely related to the older [1618]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 [1619]BSOD.) The following entry from the [1620]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. _________________________________________________________________ Node:blue wire, Next:[1621]blurgle, Previous:[1622]Blue Screen of Death, Up:[1623]= B = 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 mainstreanm slang `bodge' for a clumsy improvisation or sloppy job of work.

[UK] Spoken [1631]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.

[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 [1636]parse. 2. Any of a number of variants and extensions of BNF proper, possibly containing some or all of the [1637]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 [1638]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. _________________________________________________________________ Node:boa, Next:[1639]board, Previous:[1640]BNF, Up:[1641]= B = boa [IBM] n. Any one of the fat cables that lurk under the floor in a [1642]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'. _________________________________________________________________ Node:board, Next:[1643]boat anchor, Previous:[1644]boa, Up:[1645]= B = board n. 1.

Obsolete but still working hardware, especially when used of an old S100-bus hobbyist system; originally a term of annoyance, but became more and more affectionate as the hardware became more and more obsolete. _________________________________________________________________ Node:bob, Next:[1652]bodysurf code, Previous:[1653]boat anchor, Up:[1654]= B = bob n. At [1655]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 [1656]Church of the SubGenius. Nor is it acronymized from "Brother Of [1657]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 [1658]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 inexorably snowballed. 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 [1659]Bob Code describing the Bob nature. _________________________________________________________________ Node:bodysurf code, Next:[1660]BOF, Previous:[1661]bob, Up:[1662]= B = bodysurf code n.

[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.

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 [1670]Bastard Home Page.

(var. `stupid-sort') The archetypical perversely awful algorithm (as opposed to [1676]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 [1677]bogus, [1678]brute force, [1679]lasherism. 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 constant 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. Implementation of step 2 is left as an exercise for the reader. _________________________________________________________________ Node:bogometer, Next:[1680]BogoMIPS, Previous:[1681]bogo-sort, Up:[1682]= B = bogometer /boh-gom'-*t-er/ n.

The elementary particle of bogosity (see [1697]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 [1698]bogosity, [1699]bogus; compare [1700]psyton, [1701]fat electrons, [1702]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 [1703]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.

Bogosity is measured with a [1720]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 [1721]microLenat. 2. The potential field generated by a [1722]bogon flux; see [1723]quantum bogodynamics.

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 [1741]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 [1742]bogometer, [1743]bogon, [1744]bogotify, and [1745]quantum bogodynamics and the related but unlisted [1746]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". _________________________________________________________________ Node:Bohr bug, Next:[1747]boink, Previous:[1748]bogus, Up:[1749]= B = Bohr bug /bohr buhg/ n.

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 [1780]boink).

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 [1806]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 [1807]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. _________________________________________________________________ Node:Borg, Next:[1808]borken, Previous:[1809]boot, Up:[1810]= B = 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 [1811]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 [1812]Halloween Documents reveal that this jargon is live within Microsoft itself. (Other companies, notably Intel and UUNet, have also occasionally been equated to the Borg.) See also [1813]Evil Empire, [1814]Internet Exploiter. In IETF circles, where direct pressure from Microsoft is not a daily reality, the Borg is sometimes Cisco. This usage commemmorates 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". _________________________________________________________________ Node:borken, Next:[1815]bot, Previous:[1816]Borg, Up:[1817]= B = borken adj. (also `borked') Common deliberate typo for `broken'. _________________________________________________________________ Node:bot, Next:[1818]bot spot, Previous:[1819]borken, Up:[1820]= B = bot n [common on IRC, MUD and among gamers; from `robot'] 1. An [1821]IRC or [1822]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 [1823]nicks 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 [1824]http://www.telefragged.com/thefatal/. 3. Term used, though less commonly, for a web [1825]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. _________________________________________________________________ Node:bot spot, Next:[1826]bottom feeder, Previous:[1827]bot, Up:[1828]= B = bot spot n. [MUD] The user on a MUD with the longest connect time.

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 [1833]netiquette. 2. Syn. for [1834]slopsucker, derived from the fishermen's and naturalists' term for finny creatures who subsist on the primordial ooze. (This sense is older.) _________________________________________________________________ Node:bottom-up implementation, Next:[1835]bounce, Previous:[1836]bottom feeder, Up:[1837]= B = 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. _________________________________________________________________ Node:bounce, Next:[1838]bounce message, Previous:[1839]bottom-up implementation, Up:[1840]= B = 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 [1841]bounce message. 2. [Stanford] To play volleyball. The now-demolished [1842]D. C. Power Lab building used by the Stanford AI Lab in the 1970s had a volleyball court on the front lawn. From 5 P.M. to 7 P.M. was the scheduled maintenance time for the computer, so every afternoon at 5 would come over the intercom the cry: "Now hear this: bounce, bounce!", followed by Brian McCune loudly bouncing a volleyball on the floor outside the offices of known volleyballers. 3. 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 [1843]boink. 4. To casually reboot a system in order to clear up a transient problem. Reported primarily among [1844]VMS and [1845]Unix users. 5. [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.

[common] Notification message returned to sender by a site unable to relay [1850]email to the intended [1851]Internet address recipient or the next link in a [1852]bang path (see [1853]bounce, sense 1). Reasons might include a nonexistent or misspelled username or a [1854]down relay site. Bounce messages can themselves fail, with occasionally ugly results; see [1855]sorcerer's apprentice mode and [1856]software laser. The terms `bounce mail' and `barfmail' are also common. _________________________________________________________________ Node:boustrophedon, Next:[1857]box, Previous:[1858]bounce message, Up:[1859]= B = 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). _________________________________________________________________ Node:box, Next:[1860]boxed comments, Previous:[1861]boustrophedon, Up:[1862]= B = box n. 1. 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', `MS-DOS box', etc.) "We preprocess the data on Unix boxes before handing it up to the mainframe." 2. [IBM] Without qualification but within an SNA-using site, this refers specifically to an IBM front-end processor or FEP /F-E-P/. An FEP is a small computer necessary to enable an IBM [1863]mainframe to communicate beyond the limits of the [1864]dinosaur pen. Typically used in expressions like the cry that goes up when an SNA network goes down: "Looks like the [1865]box has fallen over." (See [1866]fall over.)

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 [1873]winged comments. _________________________________________________________________ Node:boxen, Next:[1874]boxology, Previous:[1875]boxed comments, Up:[1876]= B = boxen /bok'sn/ pl.n. [very common; by analogy with [1877]VAXen] Fanciful plural of [1878]box often encountered in the phrase `Unix boxen', used to describe commodity [1879]Unix hardware.

Compare [1888]wonky, [1889]demented. Note that the noun `bozo' occurs in slang, but the mainstream adjectival form would be `bozo-like' or (in New England) `bozoish'. _________________________________________________________________ Node:BQS, Next:[1890]brain dump, Previous:[1891]bozotic, Up:[1892]= B = BQS /B-Q-S/ adj.

[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 [1897]core dump in that it saves a lot of useful [1898]state before an exit. "You'll have to give me a brain dump on FOOBAR before you start your new job at HackerCorp." See [1899]core dump (sense 4). At Sun, this is also known as `TOI' (transfer of information). _________________________________________________________________ Node:brain fart, Next:[1900]brain-damaged, Previous:[1901]brain dump, Up:[1902]= B = brain fart n. The actual result of a [1903]braino, as opposed to the mental glitch that is the braino itself.

[common; generalization of `Honeywell Brain Damage' (HBD), a theoretical disease invented to explain certain utter cretinisms in Honeywell [1907]Multics] adj. Obviously wrong; [1908]cretinous; [1909]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.

Debugging statements inserted into a program that emit output or log indicators of the program's [1927]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 `footrinting'). _________________________________________________________________ Node:break, Next:[1928]break-even point, Previous:[1929]bread crumbs, Up:[1930]= B = break 1. vt. To cause to be [1931]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 [1932]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 a few years ago. _________________________________________________________________ Node:break-even point, Next:[1933]breath-of-life packet, Previous:[1934]break, Up:[1935]= B = 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 [1936]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 [1937]VAXen in the early and mid-1980s. A FOOGOL implementation is available at the Retrocomputing Museum [1938]http://www.ccil.org/retro. _________________________________________________________________ Node:breath-of-life packet, Next:[1939]breedle, Previous:[1940]break-even point, Up:[1941]= B = breath-of-life packet n. [XEROX PARC] An Ethernet packet that contains bootstrap (see [1942]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 [1943]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. _________________________________________________________________ Node:breedle, Next:[1944]Breidbart Index, Previous:[1945]breath-of-life packet, Up:[1946]= B = breedle n.

The Breidbart Index takes into account the fact that excessive multi-posting [1951]EMP is worse than excessive cross-posting [1952]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". _________________________________________________________________ Node:bring X to its knees, Next:[1953]brittle, Previous:[1954]Breidbart Index, Up:[1955]= B = bring X to its knees v. [common] To present a machine, operating system, piece of software, or algorithm with a load so extreme or [1956]pathological that it grinds to a halt. "To bring a MicroVAX to its knees, try twenty users running [1957]vi -- or four running [1958]EMACS." Compare [1959]hog. _________________________________________________________________ Node:brittle, Next:[1960]broadcast storm, Previous:[1961]bring X to its knees, Up:[1962]= B = 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 [1963]robust. _________________________________________________________________ Node:broadcast storm, Next:[1964]brochureware, Previous:[1965]brittle, Up:[1966]= B = 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 [1967]network meltdown; compare [1968]mail storm. _________________________________________________________________ Node:brochureware, Next:[1969]broken, Previous:[1970]broadcast storm, Up:[1971]= B = brochureware n. Planned but non-existent product like [1972]vaporware, but with the added implication that marketing is actively selling and promoting it (they've printed brochures). Brochureware is often deployed as a strategic weapon; the idea is to con customers into not committing to an existing product of the competition's. It is a safe bet that when a brochureware product finally becomes real, it will be more expensive than and inferior to the alternatives that had been available for years. _________________________________________________________________ Node:broken, Next:[1973]broken arrow, Previous:[1974]brochureware, Up:[1975]= B = broken adj. 1.

[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 [1979]down computer). On a PC, simulated with `->/_', with the two center characters overstruck.

[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.

"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 [1994]bazaar); too often, [1995]management still does. See also [1996]creationism, [1997]second-system effect, [1998]optimism. _________________________________________________________________ Node:brown-paper-bag bug, Next:[1999]browser, Previous:[2000]Brooks's Law, Up:[2001]= B = 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. _________________________________________________________________ Node:browser, Next:[2002]BRS, Previous:[2003]brown-paper-bag bug, Up:[2004]= B = 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. _________________________________________________________________ Node:BRS, Next:[2005]brute force, Previous:[2006]browser, Up:[2007]= B = BRS /B-R-S/ n. Syn. [2008]Big Red Switch. This abbreviation is fairly common on-line. _________________________________________________________________ Node:brute force, Next:[2009]brute force and ignorance, Previous:[2010]BRS, Up:[2011]= B = 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 [2012]brute force and ignorance). The [2013]canonical example of a brute-force algorithm is associated with the `traveling salesman problem' (TSP), a classical [2014]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 [2015]bignum). Sometimes, unfortunately, there is no better general solution than brute force. See also [2016]NP-. 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 [2017]ha ha only serious, but the original Unix kernel's preference for simple, robust, and portable algorithms over [2018]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. _________________________________________________________________ Node:brute force and ignorance, Next:[2019]BSD, Previous:[2020]brute force, Up:[2021]= B = brute force and ignorance n. A popular design technique at many software houses -- [2022]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 [2023]larval stage programming; unfortunately, many never outgrow it.

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 [2033]4.2, [2034]Unix, [2035]USG Unix. _________________________________________________________________ Node:BSOD, Next:[2036]BUAF, Previous:[2037]BSD, Up:[2038]= B = BSOD /B-S-O-D/ Very commmon abbreviation for [2039]Blue Screen of Death. Both spoken and written. _________________________________________________________________ Node:BUAF, Next:[2040]BUAG, Previous:[2041]BSOD, Up:[2042]= B = BUAF // n. [abbreviation, from alt.fan.warlord] Big Ugly ASCII Font -- a special form of [2043]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 [2044]banner (sense 2) programs. These are sometimes used to render one's name in a [2045]sig block, and are critically referred to as `BUAF's. See [2046]warlording. _________________________________________________________________ Node:BUAG, Next:[2047]bubble sort, Previous:[2048]BUAF, Up:[2049]= B = BUAG // n. [abbreviation, from alt.fan.warlord] Big Ugly ASCII Graphic. Pejorative term for ugly [2050]ASCII art, especially as found in [2051]sig blocks. For some reason, mutations of the head of Bart Simpson are particularly common in the least imaginative [2052]sig blocks. See [2053]warlording. _________________________________________________________________ Node:bubble sort, Next:[2054]bucky bits, Previous:[2055]BUAG, Up:[2056]= B = 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 [2057]naive and untutored programmers, hackers consider it the [2058]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 [2059]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. _________________________________________________________________ Node:bucky bits, Next:[2060]buffer chuck, Previous:[2061]bubble sort, Up:[2062]= B = 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 [2063]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 [2064]double bucky, [2065]quadruple bucky. _________________________________________________________________ Node:buffer chuck, Next:[2066]buffer overflow, Previous:[2067]bucky bits, Up:[2068]= B = buffer chuck n. Shorter and ruder syn. for [2069]buffer overflow. _________________________________________________________________ Node:buffer overflow, Next:[2070]bug, Previous:[2071]buffer chuck, Up:[2072]= B = 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 [2073]crackers 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 [2074]overrun and [2075]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 [2076]crunches a line at a time, a short line buffer can result in [2077]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 [2078]spam, [2079]overrun screw. _________________________________________________________________ Node:bug, Next:[2080]bug-compatible, Previous:[2081]buffer overflow, Up:[2082]= B = bug n. An unwanted and unintended property of a program or piece of hardware, esp. one that causes it to malfunction. Antonym of [2083]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 [2084]COBOL) liked to tell a story in which a technician solved a [2085]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 [2086]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. 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 stereotype 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 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] _________________________________________________________________ Node:bug-compatible, Next:[2087]bug-for-bug compatible, Previous:[2088]bug, Up:[2089]= B = bug-compatible adj. [common] Said of a design or revision that has been badly compromised by a requirement to be compatible with [2090]fossils or [2091]misfeatures 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." _________________________________________________________________ Node:bug-for-bug compatible, Next:[2092]bug-of-the-month club, Previous:[2093]bug-compatible, Up:[2094]= B = bug-for-bug compatible n. Same as [2095]bug-compatible, with the additional implication that much tedious effort went into ensuring that each (known) bug was replicated. _________________________________________________________________ Node:bug-of-the-month club, Next:[2096]buglix, Previous:[2097]bug-for-bug compatible, Up:[2098]= B = 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 [2099]crackers 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 [2100]kernel-of-the-week club. _________________________________________________________________ Node:buglix, Next:[2101]bulletproof, Previous:[2102]bug-of-the-month club, Up:[2103]= B = buglix /buhg'liks/ n. [uncommon] Pejorative term referring to [2104]DEC's ULTRIX operating system in its earlier severely buggy versions. Still used to describe ULTRIX, but without nearly so much venom. Compare [2105]AIDX, [2106]HP-SUX, [2107]Nominal Semidestructor, [2108]Telerat, [2109]sun-stools. _________________________________________________________________ Node:bulletproof, Next:[2110]bullschildt, Previous:[2111]buglix, Up:[2112]= B = bulletproof adj. Used of an algorithm or implementation considered extremely [2113]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 [2114]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. [2115]armor-plated. _________________________________________________________________ Node:bullschildt, Next:[2116]bum, Previous:[2117]bulletproof, Up:[2118]= B = 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 [2119]C, Herbert Schildt's "C - The Complete Reference". One reviewer commented "The naive errors in this book would be embarassing even in a programming assignment turned in by a computer science college sophomore." _________________________________________________________________ Node:bum, Next:[2120]bump, Previous:[2121]bullschildt, Up:[2122]= B = bum 1. vt. To make highly efficient, either in time or space, often at the expense of clarity. "I managed to bum three more instructions out of that code." "I spent half the night bumming the interrupt code." In 1996, this term and the practice it describes are semi-obsolete. In [2123]elder days, John McCarthy (inventor of [2124]LISP) used to compare some efficiency-obsessed hackers among his students to "ski bums"; thus, optimization became "program bumming", and eventually just "bumming". 2. To squeeze out excess; to remove something in order to improve whatever it was removed from (without changing function; this distinguishes the process from a [2125]featurectomy). 3. n. A small change to an algorithm, program, or hardware device to make it more efficient. "This hardware bum makes the jump instruction faster." Usage: now uncommon, largely superseded by v. [2126]tune (and n. [2127]tweak, [2128]hack), though none of these exactly capture sense 2. All these uses are rare in Commonwealth hackish, because in the parent dialects of English the noun `bum' is a rude synonym for `buttocks' and the verb `bum' for buggery. _________________________________________________________________ Node:bump, Next:[2129]burble, Previous:[2130]bum, Up:[2131]= B = 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. _________________________________________________________________ Node:burble, Next:[2132]buried treasure, Previous:[2133]bump, Up:[2134]= B = burble v. [from Lewis Carroll's "Jabberwocky"] Like [2135]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. _________________________________________________________________ Node:buried treasure, Next:[2136]burn-in period, Previous:[2137]burble, Up:[2138]= B = buried treasure n. A surprising piece of code found in some program. While usually not wrong, it tends to vary from [2139]crufty to [2140]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 [2141]bubble sort! Buried treasure!" _________________________________________________________________ Node:burn-in period, Next:[2142]burst page, Previous:[2143]buried treasure, Up:[2144]= B = burn-in period n. 1. A factory test designed to catch systems with [2145]marginal components before they get out the door; the theory is that burn-in will protect customers by outwaiting the steepest part of the [2146]bathtub curve (see [2147]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 [2148]hack mode, [2149]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. _________________________________________________________________ Node:burst page, Next:[2150]busy-wait, Previous:[2151]burn-in period, Up:[2152]= B = burst page n. Syn. [2153]banner, sense 1. _________________________________________________________________ Node:busy-wait, Next:[2154]buzz, Previous:[2155]burst page, Up:[2156]= B = 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 [2157]spinning 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 time-sharing systems where a busy-waiting program may [2158]hog the processor. However, it is often unavoidable in kernel programming. In the Linux world, kernel busy-waits are usually referred to as `spinlocks'. _________________________________________________________________ Node:buzz, Next:[2159]BWQ, Previous:[2160]busy-wait, Up:[2161]= B = 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 [2162]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 [2163]spin; see also [2164]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." _________________________________________________________________ Node:BWQ, Next:[2165]by hand, Previous:[2166]buzz, Up:[2167]= B = BWQ /B-W-Q/ n. [IBM: abbreviation, `Buzz Word Quotient'] The percentage of buzzwords in a speech or documents. Usually roughly proportional to [2168]bogosity. See [2169]TLA. _________________________________________________________________ Node:by hand, Next:[2170]byte, Previous:[2171]BWQ, Up:[2172]= B = by hand adv. [common] 1. 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 [2173]eyeball search. 2. 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." _________________________________________________________________ Node:byte, Next:[2174]byte sex, Previous:[2175]by hand, Up:[2176]= B = 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 usually 8 bits, but may be 9 on 36-bit machines. Some older architectures used `byte' for quantities of 6 or 7 bits, and the PDP-10 supported `bytes' that were actually bitfields of 1 to 36 bits! These usages are now obsolete, and even 9-bit bytes have become rare in the general trend toward 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 [2177]bit. See also [2178]nybble. _________________________________________________________________ Node:byte sex, Next:[2179]bytesexual, Previous:[2180]byte, Up:[2181]= B = byte sex n.

Wrong., Previous:[2185]byte sex, Up:[2186]= B = bytesexual /bi:t`sek'shu-*l/ adj. [rare] Said of hardware, denotes willingness to compute or pass data in either [2187]big-endian or [2188]little-endian format (depending, presumably, on a [2189]mode bit somewhere). See also [2190]NUXI problem. _________________________________________________________________ Node:Bzzzt! Wrong., Next:[2191]C, Previous:[2192]bytesexual, Up:[2193]= B = Bzzzt! Wrong. /bzt rong/ excl.

The name of a programming language designed by Dennis Ritchie during the early 1970s and immediately used to reimplement [2391]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 [2392]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. See also [2393]languages of choice, [2394]indent style. 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". _________________________________________________________________ Node:C Programmer's Disease, Next:[2395]C&C, Previous:[2396]C, Up:[2397]= C = 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 [2398]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. _________________________________________________________________ Node:C&C, Next:[2399]C++, Previous:[2400]C Programmer's Disease, Up:[2401]= C = C&C // [common, esp. on news.admin.net-abuse.email] Contraction of "Coffee & Cats".

Now one of the [2407]languages of choice, although many hackers still grumble that it is the successor to either Algol 68 or [2408]Ada (depending on generation), and a prime example of [2409]second-system effect. Almost anything that can be done in any language can be done in C++, but it requires a [2410]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 [2411]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."

Frequently used in an imperative sense, as in "Can that print job, the LPT just popped a sprocket!" Synonymous with [2425]gun. It is said that the ASCII character with mnemonic CAN (0011000) was used as a kill-job character on some early OSes.

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.

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 ([2438]moose@cm.org) and a web site ([2439]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. _________________________________________________________________ Node:candygrammar, Next:[2440]canonical, Previous:[2441]Cancelmoose[tm], Up:[2442]= C = candygrammar n. A programming-language grammar that is mostly [2443]syntactic sugar; the term is also a play on `candygram'. [2444]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] _________________________________________________________________ Node:canonical, Next:[2445]card walloper, Previous:[2446]candygrammar, Up:[2447]= C = 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 [2448]Knights of the Lambda Calculus). Compare [2449]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'. _________________________________________________________________ Node:card walloper, Next:[2450]careware, Previous:[2451]canonical, Up:[2452]= C = card walloper 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 [2465]shotgun debugging, [2466]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.

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.

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 [2488]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. _________________________________________________________________ Node:cat, Next:[2489]catatonic, Previous:[2490]casting the runes, Up:[2491]= C = cat [from `catenate' via [2492]Unix cat(1)] vt. 1.

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 [2496]canonical example of bad user-interface design, because of its woefully unobvious name. It is far more often used to [2497]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 [2498]cdr.

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 mass demonstration by thousands of netters who turned their [2519]home pages 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 on in 8th-circuit Federal court and subsequently affirmed by the U.S. Supreme Court on 26 June 1997 (`White Thursday').

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. _________________________________________________________________ Node:chad, Next:[2525]chad box, Previous:[2526]cdr, Up:[2527]= C = chad /chad/ n. 1.

Historical note: One correspondent believes `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'. There is a legend that the word was originally acronymic, standing for "Card Hole Aggregate Debris", but this has all the earmarks of a [2531]backronym. _________________________________________________________________ Node:chad box, Next:[2532]chain, Previous:[2533]chad, Up:[2534]= C = chad box n. A metal box about the size of a lunchbox (or in some models a large wastebasket), for collecting the [2535]chad (sense 2) that accumulated in [2536]Iron Age card punches. You had to open the covers of the card punch periodically and empty the chad box. The [2537]bit bucket was notionally the equivalent device in the CPU enclosure, which was typically across the room in another great gray-and-blue box. _________________________________________________________________ Node:chain, Next:[2538]channel, Previous:[2539]chad box, Up:[2540]= C = chain 1. vi. [orig. from BASIC's CHAIN statement] To hand off execution to a child or successor without going through the [2541]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 [2542]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. _________________________________________________________________ Node:channel, Next:[2543]channel hopping, Previous:[2544]chain, Up:[2545]= C = channel n. [IRC] The basic unit of discussion on [2546]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). _________________________________________________________________ Node:channel hopping, Next:[2547]channel op, Previous:[2548]channel, Up:[2549]= C = channel hopping n. [common; IRC, GEnie] To rapidly switch channels on [2550]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'. _________________________________________________________________ Node:channel op, Next:[2551]chanop, Previous:[2552]channel hopping, Up:[2553]= C = channel op /chan'l op/ n. [IRC] Someone who is endowed with privileges on a particular [2554]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 [2555]kick users, to change various status bits, and to make others into CHOPs. _________________________________________________________________ Node:chanop, Next:[2556]char, Previous:[2557]channel op, Up:[2558]= C = chanop /chan'-op/ n. [IRC] See [2559]channel op. _________________________________________________________________ Node:char, Next:[2560]charityware, Previous:[2561]chanop, Up:[2562]= C = char /keir/ or /char/; rarely, /kar/ n. Shorthand for `character'. Esp. used by C programmers, as `char' is C's typename for character data. _________________________________________________________________ Node:charityware, Next:[2563]chase pointers, Previous:[2564]char, Up:[2565]= C = charityware /cha'rit-ee-weir`/ n. Syn. [2566]careware. _________________________________________________________________ Node:chase pointers, Next:[2567]chawmp, Previous:[2568]charityware, Up:[2569]= C = 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 [2570]dangling pointer and [2571]snap. 2. [Cambridge] `pointer chase' or `pointer hunt': The process of going through a [2572]core dump (sense 1), interactively or on a large piece of paper printed with hex [2573]runes, following dynamic data-structures. Used only in a debugging context. _________________________________________________________________ Node:chawmp, Next:[2574]check, Previous:[2575]chase pointers, Up:[2576]= C = 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 [2577]nybble. _________________________________________________________________ Node:check, Next:[2578]cheerfully, Previous:[2579]chawmp, Up:[2580]= C = 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 [2581]molly-guards). _________________________________________________________________ Node:cheerfully, Next:[2582]chemist, Previous:[2583]check, Up:[2584]= C = cheerfully adv. See [2585]happily. _________________________________________________________________ Node:chemist, Next:[2586]Chernobyl chicken, Previous:[2587]cheerfully, Up:[2588]= C = chemist n. [Cambridge] Someone who wastes computer time on [2589]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 [2590]life patterns. May or may not refer to someone who actually studies chemistry. _________________________________________________________________ Node:Chernobyl chicken, Next:[2591]Chernobyl packet, Previous:[2592]chemist, Up:[2593]= C = Chernobyl chicken n.

A network packet that induces a [2598]broadcast storm and/or [2599]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 [2600]Christmas tree packet. _________________________________________________________________ Node:chicken head, Next:[2601]chiclet keyboard, Previous:[2602]Chernobyl packet, Up:[2603]= C = 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 (see [2604]amoeba), Commodore's machines were notoriously crocky little [2605]bitty boxes (see also [2606]PETSCII), 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. _________________________________________________________________ Node:chiclet keyboard, Next:[2607]Chinese Army technique, Previous:[2608]chicken head, Up:[2609]= C = 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. _________________________________________________________________ Node:Chinese Army technique, Next:[2610]choad, Previous:[2611]chiclet keyboard, Up:[2612]= C = Chinese Army technique n. Syn. [2613]Mongolian Hordes technique. _________________________________________________________________ Node:choad, Next:[2614]choke, Previous:[2615]Chinese Army technique, Up:[2616]= C = 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. _________________________________________________________________ Node:choke, Next:[2617]chomp, Previous:[2618]choad, Up:[2619]= C = choke v. 1. [common] To reject input, often ungracefully. "NULs make System V's lpr(1) choke." "I tried building an [2620]EMACS binary to use [2621]X, but cpp(1) choked on all those #defines." See [2622]barf, [2623]gag, [2624]vi. 2. [MIT] More generally, to fail at any endeavor, but with some flair or bravado; the popular definition is "to snatch defeat from the jaws of victory." _________________________________________________________________ Node:chomp, Next:[2625]chomper, Previous:[2626]choke, Up:[2627]= C = chomp vi. 1. To [2628]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 [2629]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 "[2630]Verb Doubling" in the "[2631]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. _________________________________________________________________ Node:chomper, Next:[2632]CHOP, Previous:[2633]chomp, Up:[2634]= C = chomper n. Someone or something that is chomping; a loser.

[IRC] See [2641]channel op. _________________________________________________________________ Node:Christmas tree, Next:[2642]Christmas tree packet, Previous:[2643]CHOP, Up:[2644]= C = 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. _________________________________________________________________ Node:Christmas tree packet, Next:[2645]chrome, Previous:[2646]Christmas tree, Up:[2647]= C = Christmas tree packet n. A packet with every single option set for whatever protocol is in use. See [2648]kamikaze packet, [2649]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 [2650]Godzillagram. _________________________________________________________________ Node:chrome, Next:[2651]chug, Previous:[2652]Christmas tree packet, Up:[2653]= C = 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 [2654]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. _________________________________________________________________ Node:chug, Next:[2655]Church of the SubGenius, Previous:[2656]chrome, Up:[2657]= C = chug vi. To run slowly; to [2658]grind or [2659]grovel. "The disk is chugging like crazy." _________________________________________________________________ Node:Church of the SubGenius, Next:[2660]Cinderella Book, Previous:[2661]chug, Up:[2662]= C = Church of the SubGenius n. A mutant offshoot of [2663]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 [2664]slack. There is a home page at [2665]http://www.subgenius.com/. _________________________________________________________________ Node:Cinderella Book, Next:[2666]CI$, Previous:[2667]Church of the SubGenius, Up:[2668]= C = Cinderella Book [CMU] n. "Introduction to Automata Theory, Languages, and Computation", by John Hopcroft and Jeffrey Ullman, (Addison-Wesley, 1979). So called because the cover depicts a girl (putatively Cinderella) sitting in front of a Rube Goldberg device and holding a rope coming out of it. On the back cover, the device is in shambles after she has (inevitably) pulled on the rope. See also [2669]book titles. _________________________________________________________________ Node:CI$, Next:[2670]Classic C, Previous:[2671]Cinderella Book, Up:[2672]= C = CI$ // n. Hackerism for `CIS', CompuServe Information Service. The dollar sign refers to CompuServe's rather steep line charges. Often used in [2673]sig blocks just before a CompuServe address. Syn.

[a play on `Coke Classic'] The C programming language as defined in the first edition of [2678]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. _________________________________________________________________ Node:clean, Next:[2679]CLM, Previous:[2680]Classic C, Up:[2681]= C = 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 [2682]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." _________________________________________________________________ Node:CLM, Next:[2683]clobber, Previous:[2684]clean, Up:[2685]= C = 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!" _________________________________________________________________ Node:clobber, Next:[2686]clock, Previous:[2687]CLM, Up:[2688]= C = clobber vt. To overwrite, usually unintentionally: "I walked off the end of the array and clobbered the stack."

[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 100MHz, it gets warm.". See [2696]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." _________________________________________________________________ Node:clocks, Next:[2697]clone, Previous:[2698]clock, Up:[2699]= C = 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 [2700]cycle, [2701]jiffy. _________________________________________________________________ Node:clone, Next:[2702]clone-and-hack coding, Previous:[2703]clocks, Up:[2704]= C = 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. `PC clone:' a PC-BUS/ISA or EISA-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. 5. 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. 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 [2705]mung it". _________________________________________________________________ Node:clone-and-hack coding, Next:[2706]clover key, Previous:[2707]clone, Up:[2708]= C = clone-and-hack coding n.

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 [2717]LART. Syn. `clue stick'.

[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 bandwidthm. 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. _________________________________________________________________ Node:coaster, Next:[2724]COBOL, Previous:[2725]co-lo, Up:[2726]= C = 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.

[COmmon Business-Oriented Language] (Synonymous with [2730]evil.) A weak, verbose, and flabby language used by [2731]card wallopers to do boring mindless things on [2732]dinosaur mainframes. Hackers believe that all COBOL programmers are [2733]suits or [2734]code grinders, 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."

Reported from Sweden, a (hypothetical) disease one might get from coding in COBOL. The language requires code verbose beyond all reason (see [2740]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!" _________________________________________________________________ Node:cobweb site, Next:[2741]code, Previous:[2742]COBOL fingers, Up:[2743]= C = cobweb site 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. This is a mass noun, as in "How much code does it take to do a [2747]bubble sort?", or "The code is loaded at the high end of RAM." Anyone referring to software as "the software codes" is probably a [2748]newbie or a [2749]suit. _________________________________________________________________ Node:code grinder, Next:[2750]code monkey, Previous:[2751]code, Up:[2752]= C = code grinder n. 1. A [2753]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 [2754]code grinder's milieu is about as far from hackerdom as one can get and still touch a computer; the term connotes pity. See [2755]Real World, [2756]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, [2757]brute force, and utter lack of imagination.

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 [2764]management decision, or of complaining about having to live with such decisions.

[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 [2772]weenies. "Dike out that goto or the code police will get you!" The ironic usage is perhaps more common. _________________________________________________________________ Node:codes, Next:[2773]codewalker, Previous:[2774]code police, Up:[2775]= C = codes n. [scientific computing] Programs. This usage is common in people who hack supercomputers and heavy-duty [2776]number-crunching, rare to unknown elsewhere (if you say "codes" to hackers outside scientific computing, their first association is likely to be "and cyphers"). _________________________________________________________________ Node:codewalker, Next:[2777]coefficient of X, Previous:[2778]codes, Up:[2779]= C = 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." _________________________________________________________________ Node:coefficient of X, Next:[2780]cokebottle, Previous:[2781]codewalker, Up:[2782]= C = 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 [2783]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'. _________________________________________________________________ Node:cokebottle, Next:[2784]cold boot, Previous:[2785]coefficient of X, Up:[2786]= C = 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 [2787]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 [2788]bang). Since the exclamation point looks a lot like an upside down Coke bottle, Motif hackers have begun referring to this keystroke as `cokebottle'.
