A Portrait of J. Random Hacker This profile reflects detailed comments on an earlier `trial balloon' version from about a hundred Usenet respondents. Where comparatives are used, the implicit `other' is a randomly selected segment of the non-hacker population of the same size as hackerdom. An important point: Except in some relatively minor respects such as slang vocabulary, hackers don't get to be the way they are by imitating each other. Rather, it seems to be the case that the combination of personality traits that makes a hacker so conditions one's outlook on life that one tends to end up being like other hackers whether one wants to or not (much as bizarrely detailed similarities in behavior and preferences are found in genetic twins raised separately).

A Story About `Magic' Some years ago, I (GLS) was snooping around in the cabinets that housed the MIT AI Lab's PDP-10, and noticed a little switch glued to the frame of one cabinet. It was obviously a homebrew job, added by one of the lab's hardware hackers (no one knows who). You don't touch an unknown switch on a computer without knowing what it does, because you might crash the computer. The switch was labeled in a most unhelpful way. It had two positions, and scrawled in pencil on the metal switch body were the words `magic' and `more magic'. The switch was in the `more magic' position. I called another hacker over to look at it. He had never seen the switch before either. Closer examination revealed that the switch had only one wire running to it! The other end of the wire did disappear into the maze of wires inside the computer, but it's a basic fact of electricity that a switch can't do anything unless there are two wires connected to it. This switch had a wire connected on one side and no wire on its other side. It was clear that this switch was someone's idea of a silly joke. Convinced by our reasoning that the switch was inoperative, we flipped it. The computer instantly crashed. Imagine our utter astonishment. We wrote it off as coincidence, but nevertheless restored the switch to the `more magic' position before reviving the computer. A year later, I told this story to yet another hacker, David Moon as I recall. He clearly doubted my sanity, or suspected me of a supernatural belief in the power of this switch, or perhaps thought I was fooling him with a bogus saga. To prove it to him, I showed him the very switch, still glued to the cabinet frame with only one wire connected to it, still in the `more magic' position. We scrutinized the switch and its lone connection, and found that the other end of the wire, though connected to the computer wiring, was connected to a ground pin. That clearly made the switch doubly useless: not only was it electrically nonoperative, but it was connected to a place that couldn't affect anything anyway. So we flipped the switch. The computer promptly crashed. This time we ran for Richard Greenblatt, a long-time MIT hacker, who was close at hand. He had never noticed the switch before, either. He inspected it, concluded it was useless, got some diagonal cutters and {dike}d it out. We then revived the computer and it has run fine ever since. We still don't know how the switch crashed the machine. There is a theory that some circuit near the ground pin was marginal, and flipping the switch changed the electrical capacitance enough to upset the circuit as millionth-of-a-second pulses went through it. But we'll never know for sure; all we can really say is that the switch was {magic}. I still have that switch in my basement. Maybe I'm silly, but I usually keep it set on `more magic'. 1994: Another explanation of this story has since been offered. Note that the switch body was metal. Suppose that the non-connected side of the switch was connected to the switch body (usually the body is connected to a separate earth lug, but there are exceptions). The body is connected to the computer case, which is, presumably, grounded. Now the circuit ground within the machine isn't necessarily at the same potential as the case ground, so flipping the switch connected the circuit ground to the case ground, causing a voltage drop/jump which reset the machine. This was probably discovered by someone who found out the hard way that there was a potential difference between the two, and who then wired in the switch as a joke.

abbrev /*-breev'/, /*-brev'/ n. Common abbreviation for `abbreviation'.

ABEND /a'bend/, /*-bend'/ n. [ABnormal END] 1. Abnormal termination (of software); {crash}; {lossage}. Derives from an error message on the IBM 360; used jokingly by hackers but seriously mainly by {code grinder}s. Usually capitalized, but may appear as `abend'. Hackers will try to persuade you that ABEND is called `abend' because it is what system operators do to the machine late on Friday when they want to call it a day, and hence is from the German `Abend' = `Evening'. 2. [alt.callahans] Absent By Enforced Net Deprivation - used in the subject lines of postings warning friends of an imminent loss of Internet access. (This can be because of computer downtime, loss of provider, moving or illness.) Variants of this also appear: ABVND = `Absent By Voluntary Net Deprivation' and ABSEND = `Absent By Self-Enforced Net Deprivation' have been sighted.

accumulator n. obs. 1. Archaic term for a register. On-line use of it as a synonym for `register' is a fairly reliable indication that the user has been around for quite a while and/or that the architecture under discussion is quite old. The term in full is almost never used of microprocessor registers, for example, though symbolic names for arithmetic registers beginning in `A' derive from historical use of the term `accumulator' (and not, actually, from `arithmetic'). Confusingly, though, an `A' register name prefix may also stand for `address', as for example on the Motorola 680x0 family. 2. A register being used for arithmetic or logic (as opposed to addressing or a loop index), especially one being used to accumulate a sum or count of many items. This use is in context of a particular routine or stretch of code. "The FOOBAZ routine uses A3 as an accumulator." 3. One's in-basket (esp. among old-timers who might use sense 1). "You want this reviewed? Sure, just put it in the accumulator." (See {stack}.)

ACK /ak/ interj. 1. [common; from the ASCII mnemonic for 0000110] Acknowledge. Used to register one's presence (compare mainstream _Yo!_). An appropriate response to {ping} or {ENQ}. 2. [from the comic strip "Bloom County"] An exclamation of surprised disgust, esp. in "Ack pffft!" Semi-humorous. Generally this sense is not spelled in caps (ACK) and is distinguished by a following exclamation point. 3. Used to politely interrupt someone to tell them you understand their point (see {NAK}). Thus, for example, you might cut off an overly long explanation with "Ack. Ack. Ack. I get it now". 4. An affirmative. "Think we ought to ditch that damn NT server for a Linux box?" "ACK!" There is also a usage "ACK?" (from sense 1) meaning "Are you there?", often used in email when earlier mail has produced no reply, or during a lull in {talk mode} to see if the person has gone away (the standard humorous response is of course {NAK} (sense 1), i.e., "I'm not here").

Acme n. [from Greek `akme', highest point of perfection or achievement] The canonical supplier of bizarre, elaborate, and non-functional gadgetry - where Rube Goldberg and Heath Robinson (two cartoonists who specialized in elaborate contraptions) shop. The name has been humorously expanded as A (or American) Company Making Everything. (In fact, Acme was a real brand sold from Sears Roebuck catalogs in the early 1900s.) Describing some X as an "Acme X" either means "This is {insanely great}", or, more likely, "This looks {insanely great} on paper, but in practice it's really easy to shoot yourself in the foot with it." Compare {pistol}. This term, specially cherished by American hackers and explained here for the benefit of our overseas brethren, comes from the Warner Brothers' series of "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 wooden crates labeled prominently with the Acme name - which, probably not by coincidence, was the trade name of the animation rotation board used by cartoonists since forever. Acme devices invariably malfunctioned in improbable and violent ways.

acolyte n. obs. [TMRC] An {OSU} privileged enough to submit data and programs to a member of the {priesthood}.

Ada n. A {{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 was "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, {elephantine} bulk.

address harvester n. A robot that searches web pages and/or filters netnews traffic looking for valid email addresses. Some address harvesters are benign, used only for compiling address directories. Most, unfortunately, are run by miscreants compiling address lists to {spam}. Address harvesters can be foiled by a {teergrube}.

adger /aj'r/ vt. [UCLA mutant of {nadger}, poss. also from the middle name of an infamous {tenured graduate student}] To make a bonehead move with consequences that could have been foreseen with even slight mental effort. E.g., "He started removing files and promptly adgered the whole project". Compare {dumbass attack}.

ad-hockery /ad-hok'*r-ee/ n. [Purdue] 1. Gratuitous assumptions made inside certain programs, esp. expert systems, which lead to the appearance of semi-intelligent behavior but are in fact entirely arbitrary. For example, fuzzy-matching of input tokens that might be typing errors against a symbol table can make it look as though a program knows how to spell. 2. Special-case code to cope with some awkward input that would otherwise cause a program to {choke}, presuming normal inputs are dealt with in some cleaner and more regular way. Also called `ad-hackery', `ad-hocity' (/ad-hos'*-tee/), `ad-crockery'. See also {ELIZA effect}.

admin /ad-min'/ n. Short for `administrator'; very commonly used in speech or on-line to refer to the systems person in charge on a computer. Common constructions on this include `sysadmin' and `site admin' (emphasizing the administrator's role as a site contact for email and news) or `newsadmin' (focusing specifically on news). Compare {postmaster}, {sysop}, {system mangler}.

ADVENT /ad'vent/ n. The prototypical computer adventure game, first designed by Will Crowther on the {PDP-10} in the mid-1970s as an attempt at computer-refereed fantasy gaming, and expanded into a puzzle-oriented game by Don Woods at Stanford in 1976. (Woods had been one of the authors of {INTERCAL}.) Now better known as Adventure or Colossal Cave Adventure, but the {{TOPS-10}} operating system permitted only six-letter filenames. See also {vadding}, {Zork}, and {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' {xyzzy} and {plugh} also derive from this game. Crowther, by the way, participated in the exploration of the Mammoth & Flint Ridge cave system; it actually _has_ a `Colossal Cave' and a `Bedquilt' as in the game, and the `Y2' that also turns up is cavers' jargon for a map reference to a secondary entrance. ADVENT sources are available for FTP at `ftp://ftp.wustl.edu/doc/misc/if-archive/games/source/advent.tar.Z'. There is a Colossal Cave Adventure page (http://people.delphi.com/rickadams/adventure/index.html).

AFAIK // n. [Usenet] Abbrev. for "As Far As I Know".

AFJ // n. Written-only abbreviation for "April Fool's Joke". Elaborate April Fool's hoaxes are a long-established tradition on Usenet and Internet; see {kremvax} for an example. In fact, April Fool's Day is the _only_ seasonal holiday consistently marked by customary observances on Internet and other hacker networks.

AFK [MUD] Abbrev. for "Away From Keyboard". Used to notify others that you will be momentarily unavailable online. eg. "Let's not go kill that frost giant yet, I need to go AFK to make a phone call". Often MUDs will have a command to politely inform others of your absence when they try to talk with you. The term is not restricted to MUDs, however, and has become common in many chat situations, from IRC to Unix talk.

AI /A-I/ n. Abbreviation for `Artificial Intelligence', so common that the full form is almost never written or spoken among hackers.

AI koans /A-I koh'anz/ pl.n. A series of pastiches of Zen teaching riddles created by Danny Hillis at the MIT AI Lab around various major figures of the Lab's culture (several are included under {Some AI Koans} in Appendix A). See also {ha ha only serious}, {mu}, and {{hacker humor}}.

AI-complete /A-I k*m-pleet'/ adj. [MIT, Stanford: by analogy with `NP-complete' (see {NP-})] Used to describe problems or subproblems in AI, to indicate that the solution presupposes a solution to the `strong AI problem' (that is, the synthesis of a human-level intelligence). A problem that is AI-complete is, in other words, just too hard. Examples of AI-complete problems are `The Vision Problem' (building a system that can see as well as a human) and `The Natural Language Problem' (building a system that can understand and speak a natural language as well as a human). These may appear to be modular, but all attempts so far (1999) to solve them have foundered on the amount of context information and `intelligence' they seem to require. See also {gedanken}.

AIDS /aydz/ n. Short for A* Infected Disk Syndrome (`A*' is a {glob} pattern that matches, but is not limited to, Apple or Amiga), this condition is quite often the result of practicing unsafe {SEX}. See {virus}, {worm}, {Trojan horse}, {virgin}.

AIDX /ayd'k*z/ n. 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 ({BSD} and USG Unix) became a {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 {HP-SUX}. Also, compare {Macintrash}, {Nominal Semidestructor}, {ScumOS}, {sun-stools}.

airplane rule n. "Complexity increases the possibility of failure; a twin-engine airplane has twice as many engine problems as a single-engine airplane." By analogy, in both software and electronics, the rule that simplicity increases robustness. It is correspondingly argued that the right way to build reliable systems is to put all your eggs in one basket, after making sure that you've built a really _good_ basket. See also {KISS Principle}, {elegant}.

Alderson loop n. [Intel] A special version of an {infinite loop} where there is an exit condition available, but inaccessible in the current implementation of the code. Typically this is created while debugging user interface code. An example would be when there is a menu stating, "Select 1-3 or 9 to quit" and 9 is not allowed by the function that takes the selection from the user. This term received its name from a programmer who had coded a modal message box in MSAccess with no Ok or Cancel buttons, thereby disabling the entire program whenever the box came up. The message box had the proper code for dismissal and even was set up so that when the non-existent Ok button was pressed the proper code would be called.

aliasing bug n. A class of subtle programming errors that can arise in code that does dynamic allocation, esp. via `malloc(3)' or equivalent. If several pointers address (`aliases for') a given hunk of storage, it may happen that the storage is freed or reallocated (and thus moved) through one alias and then referenced through another, which may lead to subtle (and possibly intermittent) lossage depending on the state and the allocation history of the malloc {arena}. Avoidable by use of allocation strategies that never alias allocated core, or by use of higher-level languages, such as {LISP}, which employ a garbage collector (see {GC}). Also called a {stale pointer bug}. See also {precedence lossage}, {smash the stack}, {fandango on core}, {memory leak}, {memory smash}, {overrun screw}, {spam}. Historical note: Though this term is nowadays associated with C programming, it was already in use in a very similar sense in the Algol-60 and FORTRAN communities in the 1960s.

Alice and Bob n. The archetypal individuals used as examples in discussions of cryptographic protocols. Originally, theorists would say something like: "A communicates with someone who claims to be B, So to be sure, A tests that B knows a secret number K. So A sends to B a random number X. B then forms Y by encrypting X under key K and sends Y back to A" Because this sort of thing is quite hard to follow, theorists stopped using the unadorned letters A and B to represent the main players and started calling them Alice and Bob. So now we say "Alice communicates with someone claiming to be Bob, and to be sure, Alice tests that Bob knows a secret number K. Alice sends to Bob a random number X. Bob then forms Y by encrypting X under key K and sends Y back to Alice". A whole mythology rapidly grew up around the metasyntactic names; see `http://www.conceptlabs.co.uk/extras/ZurichSeminarSpeech3.htm'. 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.

all your base are belong to us A declaration of victory or superiority. The phrase stems from a 1991 adaptation of Toaplan's "Zero Wing" shoot-'em-up arcade game for the Sega Genesis game console. A brief introduction was added to the opening screen, and it has what many consider to be the worst Japanese-to-English translation in video game history. The introduction shows the bridge of a starship in chaos as a Borg-like figure named CATS materializes and says, "How are you gentlemen!! All your base are belong to us." [sic] In 2001, this amusing mistranslation spread virally through the internet, bringing with it a slew of JPEGs and a movie of hacked photographs, each showing a street sign, store front, package label, etc. hacked to read "All your base are belong to us" or one of the other dopy lines from the game. When the phrase is used properly, the overall effect is both screamingly funny and somewhat chilling, reminiscent of the B movie "They Live". The original has been generalized to "All your X are belong to us", where X is filled in to connote a sinister takeover of some sort. Thus, "When Joe signed up for his new job at Yoyodyne, he had to sign a draconian NDA. It basically said, `All your code are belong to us.'" Has many of the connotations of "Resistance is futile; you will be assimilated" (see {Borg}). Considered silly, and most likely to be used by the type of person that finds {Jeff K.} hilarious.

all-elbows adj. [MS-DOS] Of a TSR (terminate-and-stay-resident) IBM PC program, such as the N pop-up calendar and calculator utilities that circulate on {BBS} systems: unsociable. Used to describe a program that rudely steals the resources that it needs without considering that other TSRs may also be resident. One particularly common form of rudeness is lock-up due to programs fighting over the keyboard interrupt. See {rude}, also {mess-dos}.

alpha geek n. [from animal ethologists' `alpha male'] The most technically accomplished or skillful person in some implied context. "Ask Larry, he's the alpha geek here."

alpha particles n. See {bit rot}.

alt /awlt/ 1. n. The alt shift key on an IBM PC or {clone} keyboard; see {bucky bits}, sense 2 (though typical PC usage does not simply set the 0200 bit). 2. n. The `option' key on a Macintosh; use of this term usually reveals that the speaker hacked PCs before coming to the Mac (see also {feature key}, which is sometimes _incorrectly_ called `alt'). 3. 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 {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".

alt bit /awlt bit/ [from alternate] adj. See {meta bit}.

Aluminum Book n. [MIT] "Common LISP: The Language", by Guy L. Steele Jr. (Digital Press, first edition 1984, second edition 1990). Note that due to a technical screwup some printings of the second edition are actually of a color the author describes succinctly as "yucky green". See also {{book titles}}.

ambimouseterous /am-b*-mows'ter-us/ or /am-b*-mows'trus/ adj. [modeled on ambidextrous] Able to use a mouse with either hand.

Amiga n A series of personal computer models originally sold by Commodore, based on 680x0 processors, custom support chips and an operating system that combined some of the best features of Macintosh and Unix with compatibility with neither. The Amiga was released just as the personal computing world standardized on IBM-PC clones. This prevented it from gaining serious market share, despite the fact that the first Amigas had a substantial technological lead on the IBM XTs of the time. Instead, it acquired a small but zealous population of enthusiastic hackers who dreamt of one day unseating the clones (see {Amiga Persecution Complex}). The traits of this culture are both spoofed and illuminated in The BLAZE Humor Viewer (http://www.blazemonger.com/BM/). The strength of the Amiga platform seeded a small industry of companies building software and hardware for the platform, especially in graphics and video applications (see {video toaster}). Due to spectacular mismanagement, Commodore did hardly any R&D, allowing the competition to close Amiga's technological lead. After Commodore went bankrupt in 1994 the technology passed through several hands, none of whom did much with it. However, the Amiga is still being produced in Europe under license and has a substantial number of fans, which will probably extend the platform's life considerably.

Amiga Persecution Complex n. The disorder suffered by a particularly egregious variety of {bigot}, those who believe that the marginality of their preferred machine is the result of some kind of industry-wide conspiracy (for without a conspiracy of some kind, the eminent superiority of their beloved shining jewel of a platform would obviously win over all, market pressures be damned!) Those afflicted are prone to engaging in {flame war}s and calling for boycotts and mailbombings. Amiga Persecution Complex is by no means limited to Amiga users; NeXT, {NeWS}, {OS/2}, Macintosh, {LISP}, and {GNU} users are also common victims. {Linux} users used to display symptoms very frequently before Linux started winning; some still do. See also {newbie}, {troll}, {holy wars}, {weenie}, {Get a life!}.

amoeba n. Humorous term for the Commodore Amiga personal computer.

amp off vt. [Purdue] To run in {background}. From the Unix shell `&' operator.

amper n. Common abbreviation for the name of the ampersand (`&', ASCII 0100110) character. See {{ASCII}} for other synonyms.

Angband n. /ang'band/ Like {nethack}, {moria}, and {rogue}, one of the large freely distributed Dungeons-and-Dragons-like simulation games, available for a wide range of machines and operating systems. The name is from Tolkien's Pits of Angband (compare {elder days}, {elvish}). Has been described as "Moria on steroids"; but, unlike Moria, many aspects of the game are customizable. This leads many hackers and would-be hackers into fooling with these instead of doing productive work. There are many Angband variants, of which the most notorious is probably the rather whimsical Zangband. In this game, when a key that does not correspond to a command is pressed, the game will display "Type ? for help" 50% of the time. The other 50% of the time, random error messages including "An error has occurred because an error of type 42 has occurred" and "Windows 95 uninstalled successfully" will be displayed. Zangband also allows the player to kill Santa Claus (who has some really good stuff, but also has a lot of friends), "Bull Gates", and Barney the Dinosaur (but be watchful; Barney has a nasty case of halitosis). There is an official angband home page at `http://www.phial.com/angband' and a zangband one at `http://thangorodrim.angband.org'. See also {Random Number God}.

angle brackets n. Either of the characters `

angry fruit salad n. A bad visual-interface design that uses too many colors. (This term derives, of course, from the bizarre day-glo colors found in canned fruit salad.) Too often one sees similar effects from interface designers using color window systems such as {X}; there is a tendency to create displays that are flashy and attention-getting but uncomfortable for long-term use.

annoybot /*-noy-bot/ n. [IRC] See {bot}.

annoyware n. A type of {shareware} that frequently disrupts normal program operation to display requests for payment to the author in return for the ability to disable the request messages. (Also called `nagware') The requests generally require user action to acknowledge the message before normal operation is resumed and are often tied to the most frequently used features of the software. See also {careware}, {charityware}, {crippleware}, {freeware}, {FRS}, {guiltware}, {postcardware}, and {-ware}; compare {payware}.

ANSI /an'see/ 1. n. [techspeak] The American National Standards Institute. ANSI, along with the International Organization for Standards (ISO), standardized the C programming language (see {K&R}, {Classic C}), and promulgates many other important software standards. 2. n. [techspeak] A terminal may be said to be `ANSI' if it meets the ANSI X3.64 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 X3.64 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.

ANSI standard /an'see stan'd*rd/ The ANSI standard usage of `ANSI standard' refers to any practice which is typical or broadly done. It's most appropriately applied to things that everyone does that are not quite regulation. For example: ANSI standard shaking of a laser printer cartridge to get extra life from it, or the ANSI standard word tripling in names of usenet alt groups.

ANSI standard pizza /an'see stan'd*rd peet'z*/ [CMU] Pepperoni and mushroom pizza. Coined allegedly because most pizzas ordered by CMU hackers during some period leading up to mid-1990 were of that flavor. See also {rotary debugger}; compare {ISO standard cup of tea}.

Anthropomorphization Semantically, one rich source of jargon constructions is the hackish tendency to anthropomorphize hardware and software. English purists and academic computer scientists frequently look down on others for anthropomorphizing hardware and software, considering this sort of behavior to be characteristic of naive misunderstanding. But most hackers anthropomorphize freely, frequently describing program behavior in terms of wants and desires. Thus it is common to hear hardware or software talked about as though it has homunculi talking to each other inside it, with intentions and desires. Thus, one hears "The protocol handler got confused", or that programs "are trying" to do things, or one may say of a routine that "its goal in life is to X". Or: "You can't run those two cards on the same bus; they fight over interrupt 9." One even hears explanations like "... and its poor little brain couldn't understand X, and it died." Sometimes modelling things this way actually seems to make them easier to understand, perhaps because it's instinctively natural to think of anything with a really complex behavioral repertoire as `like a person' rather than `like a thing'. At first glance, to anyone who understands how these programs actually work, this seems like an absurdity. As hackers are among the people who know best how these phenomena work, it seems odd that they would use language that seems to ascribe 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 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 often modelled using the intentional stance. It has also been argued that the anthropomorphization of software and hardware reflects a blurring of the boundary between the programmer and his artifacts - the human qualities belong to the programmer and the code merely expresses these qualities as his/her proxy. On this view, a hacker saying a piece of code 'got confused' is really saying that _he_ (or she) was confused about exactly what he wanted the computer to do, the code naturally incorporated this confusion, and the code expressed the programmer's confusion when executed by crashing or otherwise misbehaving. Note that by displacing from "I got confused" to "It got confused", the programmer is not avoiding responsibility, but rather getting some analytical distance in order to be able to consider the bug dispassionately. Both explanations accurately model hacker psychology, and should be considered complementary rather than competing.

AOL! n. [Usenet] Common synonym for "Me, too!" alluding to the legendary propensity of America Online users to utter contentless "Me, too!" postings. The number of exclamation points following varies from zero to five or so. The pseudo-HTML Me, too! is also frequently seen. See also {September that never ended}.

app /ap/ n. Short for `application program', as opposed to a systems program. Apps are what systems vendors are forever chasing developers to create for their environments so they can sell more boxes. Hackers tend not to think of the things they themselves run as apps; thus, in hacker parlance the term excludes compilers, program editors, games, and messaging systems, though a user would consider all those to be apps. (Broadly, an app is often a self-contained environment for performing some well-defined task such as `word processing'; hackers tend to prefer more general-purpose tools.) See {killer app}; oppose {tool}, {operating system}.

arena n. [common; Unix] The area of memory attached to a process by `brk(2)' and `sbrk(2)' and used by `malloc(3)' as dynamic storage. So named from a `malloc: corrupt arena' message emitted when some early versions detected an impossible value in the free block list. See {overrun screw}, {aliasing bug}, {memory leak}, {memory smash}, {smash the stack}.

arg /arg/ n. Abbreviation for `argument' (to a function), used so often as to have become a new word (like `piano' from `pianoforte'). "The sine function takes 1 arg, but the arc-tangent function can take either 1 or 2 args." Compare {param}, {parm}, {var}.

ARMM n. [acronym, `Automated Retroactive Minimal Moderation'] A Usenet {cancelbot} created by Dick Depew of Munroe Falls, Ohio. ARMM was intended to automatically cancel posts from anonymous-posting sites. Unfortunately, the robot's recognizer for anonymous postings triggered on its own automatically-generated control messages! Transformed by this stroke of programming ineptitude into a monster of Frankensteinian proportions, it broke loose on the night of March 31, 1993 and proceeded to {spam} news.admin.policy with a recursive explosion of over 200 messages. ARMM's bug produced a recursive {cascade} of messages each of which mechanically added text to the ID and Subject and some other headers of its parent. This produced a flood of messages in which each header took up several screens and each message ID and subject line got longer and longer and longer. Reactions varied from amusement to outrage. The pathological messages crashed at least one mail system, and upset people paying line charges for their Usenet feeds. One poster described the ARMM debacle as "instant Usenet history" (also establishing the term {despew}), and it has since been widely cited as a cautionary example of the havoc the combination of good intentions and incompetence can wreak on a network. Compare {Great Worm}; {sorcerer's apprentice mode}. See also {software laser}, {network meltdown}.

armor-plated n. Syn. for {bulletproof}.

asbestos adj. [common] Used as a modifier to anything intended to protect one from {flame}s; also in other highly {flame}-suggestive usages. See, for example, {asbestos longjohns} and {asbestos cork award}.

asbestos cork award n. Once, long ago at MIT, there was a {flamer} so consistently obnoxious that another hacker designed, had made, and distributed posters announcing that said flamer had been nominated for the `asbestos cork award'. (Any reader in doubt as to the intended application of the cork should consult the etymology under {flame}.) Since then, it is agreed that only a select few have risen to the heights of bombast required to earn this dubious dignity -- but there is no agreement on _which_ few.

asbestos longjohns n. Notional garments donned by {Usenet} posters just before emitting a remark they expect will elicit {flamage}. This is the most common of the {asbestos} coinages. Also `asbestos underwear', `asbestos overcoat', etc.

ASCII /as'kee/ n. [originally an acronym (American Standard Code for Information Interchange) but now merely conventional] The predominant character set encoding of present-day computers. The standard version uses 7 bits for each character, whereas most earlier codes (including early drafts of ASCII prior to June 1961) used fewer. This change allowed the inclusion of lowercase letters -- a major {win} -- but it did not provide for accented letters or any other letterforms not used in English (such as the German sharp-S or the ae-ligature which is a letter in, for example, Norwegian). It could be worse, though. It could be much worse. See {{EBCDIC}} to understand how. A history of ASCII and its ancestors is at `http://www.wps.com/texts/codes/index.html'. Computers are much pickier and less flexible about spelling than humans; thus, hackers need to be very precise when talking about characters, and have developed a considerable amount of verbal shorthand for them. Every character has one or more names -- some formal, some concise, some silly. Common jargon names for ASCII characters are collected here. See also individual entries for {bang}, {excl}, {open}, {ques}, {semi}, {shriek}, {splat}, {twiddle}, and {Yu-Shiang Whole Fish}. This list derives from revision 2.3 of the Usenet ASCII pronunciation guide. Single characters are listed in ASCII order; character pairs are sorted in by first member. For each character, common names are given in rough order of popularity, followed by names that are reported but rarely seen; official ANSI/CCITT names are surrounded by brokets: . Square brackets mark the particularly silly names introduced by {INTERCAL}. The abbreviations "l/r" and "o/c" stand for left/right and "open/close" respectively. Ordinary parentheticals provide some usage information. ! Common: {bang}; pling; excl; not; shriek; ball-bat; .

Rare: ; gozinta; thru; pipesinta (last three from UNIX); [spike]. ~ Common: ; squiggle; {twiddle}; not. Rare: approx; wiggle; swung dash; enyay; [sqiggle (sic)]. The pronunciation of `#' as `pound' is common in the U.S. but a bad idea; {{Commonwealth Hackish}} has its own, rather more apposite use of `pound sign' (confusingly, on British keyboards the 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 {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 {angle brackets}). Some other common usages cause odd overlaps. The `#', `$', `>', and `&' characters, for example, are all pronounced "hex" in different communities because various assemblers use them as a prefix tag for hexadecimal constants (in particular, `#' in many assembler-programming cultures, `$' in the 6502 world, `>' at Texas Instruments, and `&' on the BBC Micro, Sinclair, and some Z80 machines). See also {splat}. The inability of ASCII text to correctly represent any of the world's other major languages makes the designers' choice of 7 bits look more and more like a serious {misfeature} as the use of international networks continues to increase (see {software rot}). Hardware and software from the U.S. still tends to embody the assumption that ASCII is the universal character set and that characters have 7 bits; this is a major irritant to people who want to use a character set suited to their own languages. Perversely, though, efforts to solve this problem by proliferating `national' character sets produce an evolutionary pressure to use a _smaller_ subset common to all those in use.

ASCII art n. The fine art of drawing diagrams using the ASCII character set (mainly `|', `-', `/', `\', and `+'). Also known as `character graphics' or `ASCII graphics'; see also {boxology}. Here is a serious example: o----)||(--+--||-+ | +-\/\/-+--o - T C N )||( | | | | P E )||( +-->|-+--)---+--|(--+-o U )||( | | | GND T o----)||(--+--|

ASCIIbetical order /as'kee-be'-t*-kl or'dr/ adj.,n. Used to indicate that data is sorted in ASCII collated order rather than alphabetical order. This lexicon is sorted in something close to ASCIIbetical order, but with case ignored and entries beginning with non-alphabetic characters moved to the beginning. "At my video store, they used their computer to sort the videos into ASCIIbetical order, so I couldn't find `"Crocodile" Dundee' until I thought to look before `2001' and `48 HRS.'!"

astroturfing n. The use of paid shills to create the impression of a popular movement, through means like letters to newspapers from soi-disant `concerned citizens', paid opinion pieces, and the formation of grass-roots lobbying groups that are actually funded by a PR group (astroturf is fake grass; hence the term). 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. It also set anybody defending Microsoft on the net for the accusation "You're just astroturfing!".

atomic adj. [from Gk. `atomos', indivisible] 1. Indivisible; cannot be split up. For example, an instruction may be said to do several things `atomically', i.e., all the things are done immediately, and there is no chance of the instruction being half-completed or of another being interspersed. Used esp. to convey that an operation cannot be screwed up by interrupts. "This routine locks the file and increments the file's semaphore atomically." 2. [primarily techspeak] Guaranteed to complete successfully or not at all, usu. refers to database transactions. If an error prevents a partially-performed transaction from proceeding to completion, it must be "backed out," as the database must not be left in an inconsistent state. Computer usage, in either of the above senses, has none of the connotations that `atomic' has in mainstream English (i.e. of particles of matter, nuclear explosions etc.).

attoparsec n. About an inch. `atto-' is the standard SI prefix for multiplication by 10^(-18). A parsec (parallax-second) is 3.26 light-years; an attoparsec is thus 3.26 * 10^(-18) light years, or about 3.1 cm (thus, 1 attoparsec/{microfortnight} equals about 1 inch/sec). This unit is reported to be in use (though probably not very seriously) among hackers in the U.K. See {micro-}.

AUP /A-U-P/ Abbreviation, "Acceptable Use Policy". The policy of a given ISP which sets out what the ISP considers to be (un)acceptable uses of its Internet resources.

autobogotiphobia /aw'toh-boh-got`*-foh'bee-*/ n. See {bogotify}.

autoconfiscate [originally from Cygnus Solutions, later Red Hat Software] To set up or modify a source-code {distribution} so that it configures and builds using the GNU project's autoconf/automake/libtools suite. Among open-source hackers, a mere running binary of a program is not considered a full release; what's interesting is a source tree that can be built into binaries using standard tools. Since the mid-1990s, autoconf and friends been the standard way to adapt a distribution for portability so that it casn be built on multiple operating systems without change.

automagically /aw-toh-maj'i-klee/ adv. Automatically, but in a way that, for some reason (typically because it is too complicated, or too ugly, or perhaps even too trivial), the speaker doesn't feel like explaining to you. See {magic}. "The C-INTERCAL compiler generates C, then automagically invokes `cc(1)' to produce an executable." This term is quite old, going back at least to the mid-70s in jargon and probably much earlier. The word `automagic' occurred in advertising (for a shirt-ironing gadget) as far back as the late 1940s.

avatar n. Syn. [in Hindu mythology, the incarnation of a god] 1. Among people working on virtual reality and {cyberspace} interfaces, an "avatar" is an icon or representation of a user in a shared virtual reality. The term is sometimes used on {MUD}s. 2. [CMU, Tektronix] {root}, {superuser}. There are quite a few Unix machines on which the name of the superuser account is `avatar' rather than `root'. This quirk was originated by a CMU hacker who found the terms `root' and `superuser' unimaginative, and thought `avatar' might better impress people with the responsibility they were accepting.

awk /awk/ 1. n. [Unix techspeak] An interpreted language for massaging text data developed by Alfred Aho, Peter Weinberger, and Brian Kernighan (the name derives from their initials). It is characterized by C-like syntax, a declaration-free approach to variable typing and declarations, associative arrays, and field-oriented text processing. See also {Perl}. 2. n. Editing term for an expression awkward to manipulate through normal {regexp} facilities (for example, one containing a {newline}). 3. vt. To process data using `awk(1)'. = B =
