wabbit /wab'it/ /n./

[almost certainly from Elmer Fudd's immortal line "You wascawwy wabbit!"] 1. A legendary early hack reported on a System/360 at RPI and elsewhere around 1978; this may have descended (if only by inspiration) from a hack called RABBITS reported from 1969 on a Burroughs 5500 at the University of Washington Computer Center. The program would make two copies of itself every time it was run, eventually crashing the system. 2. By extension, any hack that includes infinite self-replication but is not a virus or worm. See fork bomb and rabbit job, see also cookie monster.

WAITS /wayts/ /n./

The mutant cousin of TOPS-10 used on a handful of systems at SAIL up to 1990. There was never an `official' expansion of WAITS (the name itself having been arrived at by a rather sideways process), but it was frequently glossed as `West-coast Alternative to ITS'. Though WAITS was less visible than ITS, there was frequent exchange of people and ideas between the two communities, and innovations pioneered at WAITS exerted enormous indirect influence. The early screen modes of EMACS, for example, were directly inspired by WAITS's `E' editor -- one of a family of editors that were the first to do `real-time editing', in which the editing commands were invisible and where one typed text at the point of insertion/overwriting. The modern style of multi-region windowing is said to have originated there, and WAITS alumni at XEROX PARC and elsewhere played major roles in the developments that led to the XEROX Star, the Macintosh, and the Sun workstations. Also invented there were bucky bits -- thus, the ALT key on every IBM PC is a WAITS legacy. One notable WAITS feature seldom duplicated elsewhere was a news-wire interface that allowed WAITS hackers to read, store, and filter AP and UPI dispatches from their terminals; the system also featured a still-unusual level of support for what is now called `multimedia' computing, allowing analog audio and video signals to be switched to programming terminals.

waldo /wol'doh/ /n./

[From Robert A. Heinlein's story "Waldo"] 1. A mechanical agent, such as a gripper arm, controlled by a human limb. When these were developed for the nuclear industry in the mid-1940s they were named after the invention described by Heinlein in the story, which he wrote in 1942. Now known by the more generic term `telefactoring', this technology is of intense interest to NASA for tasks like space station maintenance. 2. At Harvard (particularly by Tom Cheatham and students), this is used instead of foobar as a metasyntactic variable and general nonsense word. See foo, bar, foobar, quux.

walk /n.,vt./

Traversal of a data structure, especially an array or linked-list data structure in core. See also codewalker, silly walk, clobber.

walk off the end of /vt./

To run past the end of an array, list, or medium after stepping through it -- a good way to land in trouble. Often the result of an off-by-one error. Compare clobber, roach, smash the stack.

walking drives /n./

An occasional failure mode of magnetic-disk drives back in the days when they were huge, clunky washing machines. Those old dinosaur parts carried terrific angular momentum; the combination of a misaligned spindle or worn bearings and stick-slip interactions with the floor could cause them to `walk' across a room, lurching alternate corners forward a couple of millimeters at a time. There is a legend about a drive that walked over to the only door to the computer room and jammed it shut; the staff had to cut a hole in the wall in order to get at it! Walking could also be induced by certain patterns of drive access (a fast seek across the whole width of the disk, followed by a slow seek in the other direction). Some bands of old-time hackers figured out how to induce disk-accessing patterns that would do this to particular drive models and held disk-drive races.

wall /interj./

[WPI] 1. An indication of confusion, usually spoken with a quizzical tone: "Wall??" 2. A request for further explication. Compare octal forty. 3. [Unix, from `write all'] /v./ To send a message to everyone currently logged in, esp. with the wall(8) utility.

It is said that sense 1 came from the idiom `like talking to a blank wall'. It was originally used in situations where, after you had carefully answered a question, the questioner stared at you blankly, clearly having understood nothing that was explained. You would then throw out a "Hello, wall?" to elicit some sort of response from the questioner. Later, confused questioners began voicing "Wall?" themselves.

wall follower /n./

A person or algorithm that compensates for lack of sophistication or native stupidity by efficiently following some simple procedure shown to have been effective in the past. Used of an algorithm, this is not necessarily pejorative; it recalls `Harvey Wallbanger', the winning robot in an early AI contest (named, of course, after the cocktail). Harvey successfully solved mazes by keeping a `finger' on one wall and running till it came out the other end. This was inelegant, but it was mathematically guaranteed to work on simply-connected mazes --- and, in fact, Harvey outperformed more sophisticated robots that tried to `learn' each maze by building an internal representation of it. Used of humans, the term is pejorative and implies an uncreative, bureaucratic, by-the-book mentality. See also code grinder; compare droid.

wall time /n./

(also `wall clock time') 1. `Real world' time (what the clock on the wall shows), as opposed to the system clock's idea of time. 2. The real running time of a program, as opposed to the number of ticks required to execute it (on a timesharing system these always differ, as no one program gets all the ticks, and on multiprocessor systems with good thread support one may get more processor time than real time).

wallpaper /n./

1. A file containing a listing (e.g., assembly listing) or a transcript, esp. a file containing a transcript of all or part of a login session. (The idea was that the paper for such listings was essentially good only for wallpaper, as evidenced at Stanford, where it was used to cover windows.) Now rare, esp. since other systems have developed other terms for it (e.g., PHOTO on TWENEX). However, the Unix world doesn't have an equivalent term, so perhaps wallpaper will take hold there. The term probably originated on ITS, where the commands to begin and end transcript files were :WALBEG and :WALEND, with default file WALL PAPER (the space was a path delimiter). 2. The background pattern used on graphical workstations (this is techspeak under the `Windows' graphical user interface to MS-DOS). 3. `wallpaper file' /n./ The file that contains the wallpaper information before it is actually printed on paper. (Even if you don't intend ever to produce a real paper copy of the file, it is still called a wallpaper file.)

wango /wang'goh/ /n./

Random bit-level grovelling going on in a system during some unspecified operation. Often used in combination with mumble. For example: "You start with the `.o' file, run it through this postprocessor that does mumble-wango -- and it comes out a snazzy object-oriented executable."

wank /wangk/ /n.,v.,adj./

[Columbia University: prob. by mutation from Commonwealth slang /v./ `wank', to masturbate] Used much as hack is elsewhere, as a noun denoting a clever technique or person or the result of such cleverness. May describe (negatively) the act of hacking for hacking's sake ("Quit wanking, let's go get supper!") or (more positively) a wizard. Adj. `wanky' describes something particularly clever (a person, program, or algorithm). Conversations can also get wanky when there are too many wanks involved. This excess wankiness is signalled by an overload of the `wankometer' (compare bogometer). When the wankometer overloads, the conversation's subject must be changed, or all non-wanks will leave. Compare `neep-neeping' (under neep-neep). Usage: U.S. only. In Britain and the Commonwealth this word is extremely rude and is best avoided unless one intends to give offense.

wannabee /won'*-bee/ /n./

(also, more plausibly, spelled `wannabe') [from a term recently used to describe Madonna fans who dress, talk, and act like their idol; prob. originally from biker slang] A would-be hacker. The connotations of this term differ sharply depending on the age and exposure of the subject. Used of a person who is in or might be entering larval stage, it is semi-approving; such wannabees can be annoying but most hackers remember that they, too, were once such creatures. When used of any professional programmer, CS academic, writer, or suit, it is derogatory, implying that said person is trying to cuddle up to the hacker mystique but doesn't, fundamentally, have a prayer of understanding what it is all about. Overuse of terms from this lexicon is often an indication of the wannabee nature. Compare newbie.

Historical note: The wannabee phenomenon has a slightly different flavor now (1993) than it did ten or fifteen years ago. When the people who are now hackerdom's tribal elders were in larval stage, the process of becoming a hacker was largely unconscious and unaffected by models known in popular culture -- communities formed spontaneously around people who, as individuals, felt irresistibly drawn to do hackerly things, and what wannabees experienced was a fairly pure, skill-focused desire to become similarly wizardly. Those days of innocence are gone forever; society's adaptation to the advent of the microcomputer after 1980 included the elevation of the hacker as a new kind of folk hero, and the result is that some people semi-consciously set out to be hackers and borrow hackish prestige by fitting the popular image of hackers. Fortunately, to do this really well, one has to actually become a wizard. Nevertheless, old-time hackers tend to share a poorly articulated disquiet about the change; among other things, it gives them mixed feelings about the effects of public compendia of lore like this one.

war dialer /n./

A cracking tool, a program that calls a given list or range of phone numbers and records those which answer with handshake tones (and so might be entry points to computer or telecommunications systems). Some of these programs have become quite sophisticated, and can now detect modem, fax, or PBX tones and log each one separately. The war dialer is one of the most important tools in the phreaker's kit. These programs evolved from early demon dialers.

warez /weirz/ /n./

Widely used in cracker subcultures to denote cracked version of commercial software, that is versions from which copy-protection has been stripped. Hackers recognize this term but don't use it themselves. See warez d00dz.

warez d00dz /weirz doodz/ /n./

A substantial subculture of crackers refer to themselves as `warez d00dz'; there is evidently some connection with B1FF here. As `Ozone Pilot', one former warez d00d, wrote:

Warez d00dz get illegal copies of copyrighted software. If it has copy protection on it, they break the protection so the software can be copied. Then they distribute it around the world via several gateways. Warez d00dz form badass group names like RAZOR and the like. They put up boards that distribute the latest ware, or pirate program. The whole point of the Warez sub-culture is to get the pirate program released and distributed before any other group. I know, I know. But don't ask, and it won't hurt as much. This is how they prove their poweress [sic]. It gives them the right to say, "I released King's Quest IVXIX before you so obviously my testicles are larger." Again don't ask...

The studly thing to do if one is a warez d00d, it appears, is emit `0-day warez', that is copies of commercial software copied and cracked on the same day as its retail release. Warez d00ds also hoard software in a big way, collecting untold megabytes of arcade-style games, pornographic GIFs, and applications they'll never use onto their hard disks. As Ozone Pilot acutely observes:

[BELONG] is the only word you will need to know. Warez d00dz want to belong. They have been shunned by everyone, and thus turn to cyberspace for acceptance. That is why they always start groups like TGW, FLT, USA and the like. Structure makes them happy. [...] Warez d00dz will never have a handle like "Pink Daisy" because warez d00dz are insecure. Only someone who is very secure with a good dose of self-esteem can stand up to the cries of fag and girlie-man. More likely you will find warez d00dz with handles like: Doctor Death, Deranged Lunatic, Hellraiser, Mad Prince, Dreamdevil, The Unknown, Renegade Chemist, Terminator, and Twin Turbo. They like to sound badass when they can hide behind their terminals. More likely, if you were given a sample of 100 people, the person whose handle is Hellraiser is the last person you'd associate with the name.

The contrast with Internet hackers is stark and instructive. See cracker, wannabee, handle, elite; compare weenie, spod.

warlording /v./

[from the Usenet group alt.fan.warlord] The act of excoriating a bloated, ugly, or derivative sig block. Common grounds for warlording include the presence of a signature rendered in a BUAF, over-used or cliched sig quotes, ugly ASCII art, or simply excessive size. The original `Warlord' was a B1FF-like newbie c.1991 who featured in his sig a particularly large and obnoxious ASCII graphic resembling the sword of Conan the Barbarian in the 1981 John Milius movie; the group name alt.fan.warlord was sarcasm, and the characteristic mode of warlording is devastatingly sarcastic praise.

warm boot /n./

See boot.

wart /n./

A small, crocky feature that sticks out of an otherwise clean design. Something conspicuous for localized ugliness, especially a special-case exception to a general rule. For example, in some versions of csh(1), single quotes literalize every character inside them except `!'. In ANSI C, the `??' syntax used for obtaining ASCII characters in a foreign environment is a wart. See also miswart.

washing machine /n./

1. Old-style 14-inch hard disks in floor-standing cabinets. So called because of the size of the cabinet and the `top-loading' access to the media packs -- and, of course, they were always set on `spin cycle'. The washing-machine idiom transcends language barriers; it is even used in Russian hacker jargon. See also walking drives. The thick channel cables connecting these were called `bit hoses' (see hose, sense 3). 2. [CMU] A machine used exclusively for washing software. CMU has clusters of these.

washing software /n./

The process of recompiling a software distribution (used more often when the recompilation is occuring from scratch) to pick up and merge together all of the various changes that have been made to the source.

water MIPS /n./

(see MIPS, sense 2) Large, water-cooled machines of either today's ECL-supercomputer flavor or yesterday's traditional mainframe type.

wave a dead chicken /v./

To perform a ritual in the direction of crashed software or hardware that one believes to be futile but is nevertheless necessary so that others are satisfied that an appropriate degree of effort has been expended. "I'll wave a dead chicken over the source code, but I really think we've run into an OS bug." Compare voodoo programming, rain dance.

weasel /n./

[Cambridge] A naive user, one who deliberately or accidentally does things that are stupid or ill-advised. Roughly synonymous with loser.

web pointer /n./

A World Wide Web URL. See also hotlink, which has slightly different connotations.

webmaster /n./

[WWW: from postmaster] The person at a site providing World Wide Web information who is responsible for maintaining the public pages and keeping the Web server running and properly configured.

wedged /adj./

1. To be stuck, incapable of proceeding without help. This is different from having crashed. If the system has crashed, it has become totally non-functioning. If the system is wedged, it is trying to do something but cannot make progress; it may be capable of doing a few things, but not be fully operational. For example, a process may become wedged if it deadlocks with another (but not all instances of wedging are deadlocks). See also gronk, locked up, hosed. 2. Often refers to humans suffering misconceptions. "He's totally wedged -- he's convinced that he can levitate through meditation." 3. [Unix] Specifically used to describe the state of a TTY left in a losing state by abort of a screen-oriented program or one that has messed with the line discipline in some obscure way.

There is some dispute over the origin of this term. It is usually thought to derive from a common description of recto-cranial inversion; however, it may actually have originated with older `hot-press' printing technology in which physical type elements were locked into type frames with wedges driven in by mallets. Once this had been done, no changes in the typesetting for that page could be made.

wedgie /n./

[Fairchild] A bug. Prob. related to wedged.

wedgitude /wedj'i-t[y]ood/ /n./

The quality or state of being wedged.

weeble /weeb'l/ /interj./

[Cambridge] Used to denote frustration, usually at amazing stupidity. "I stuck the disk in upside down." "Weeble...." Compare gurfle.

weeds /n./

1. Refers to development projects or algorithms that have no possible relevance or practical application. Comes from `off in the weeds'. Used in phrases like "lexical analysis for microcode is serious weeds...." 2. At CDC/ETA before its demise, the phrase `go off in the weeds' was equivalent to IBM's branch to Fishkill and mainstream hackerdom's jump off into never-never land.

weenie /n./

1. [on BBSes] Any of a species of luser resembling a less amusing version of B1FF that infests many BBS systems. The typical weenie is a teenage boy with poor social skills travelling under a grandiose handle derived from fantasy or heavy-metal rock lyrics. Among sysops, `the weenie problem' refers to the marginally literate and profanity-laden flamage weenies tend to spew all over a newly-discovered BBS. Compare spod, computer geek, terminal junkie, warez d00dz. 2. [Among hackers] When used with a qualifier (for example, as in Unix weenie, VMS weenie, IBM weenie) this can be either an insult or a term of praise, depending on context, tone of voice, and whether or not it is applied by a person who considers him or herself to be the same sort of weenie. Implies that the weenie has put a major investment of time, effort, and concentration into the area indicated; whether this is good or bad depends on the hearer's judgment of how the speaker feels about that area. See also bigot. 3. The semicolon character, `;' (ASCII 0111011).

Weenix /wee'niks/ /n./

[ITS] A derogatory term for Unix, derived from Unix weenie. According to one noted ex-ITSer, it is "the operating system preferred by Unix Weenies: typified by poor modularity, poor reliability, hard file deletion, no file version numbers, case sensitivity everywhere, and users who believe that these are all advantages". (Some ITS fans behave as though they believe Unix stole a future that rightfully belonged to them. See ITS, sense 2.)

well-behaved /adj./

1. [primarily MS-DOS] Said of software conforming to system interface guidelines and standards. Well-behaved software uses the operating system to do chores such as keyboard input, allocating memory and drawing graphics. Oppose ill-behaved. 2. Software that does its job quietly and without counterintuitive effects. Esp. said of software having an interface spec sufficiently simple and well-defined that it can be used as a tool by other software. See cat.

well-connected /adj./

Said of a computer installation, asserts that it has reliable email links with the network and/or that it relays a large fraction of available Usenet newsgroups. `Well-known' can be almost synonymous, but also implies that the site's name is familiar to many (due perhaps to an archive service or active Usenet users).

wetware /wet'weir/ /n./

[prob. from the novels of Rudy Rucker] 1. The human nervous system, as opposed to computer hardware or software. "Wetware has 7 plus or minus 2 temporary registers." 2. Human beings (programmers, operators, administrators) attached to a computer system, as opposed to the system's hardware or software. See liveware, meatware.

whack /v./

According to arch-hacker James Gosling (designer of NeWS, GOSMACS and Java), to "...modify a program with no idea whatsoever how it works." (See whacker.) It is actually possible to do this in nontrivial circumstances if the change is small and well-defined and you are very good at glarking things from context. As a trivial example, it is relatively easy to change all stderr writes to stdout writes in a piece of C filter code which remains otherwise mysterious.

whacker /n./

[University of Maryland: from hacker] 1. A person, similar to a hacker, who enjoys exploring the details of programmable systems and how to stretch their capabilities. Whereas a hacker tends to produce great hacks, a whacker only ends up whacking the system or program in question. Whackers are often quite egotistical and eager to claim wizard status, regardless of the views of their peers. 2. A person who is good at programming quickly, though rather poorly and ineptly.

whales /n./

See like kicking dead whales down the beach.

whalesong /n./

The peculiar clicking and whooshing sounds made by a PEP modem such as the Telebit Trailblazer as it tries to synchronize with another PEP modem for their special high-speed mode. This sound isn't anything like the normal two-tone handshake between conventional V-series modems and is instantly recognizable to anyone who has heard it more than once. It sounds, in fact, very much like whale songs. This noise is also called "the moose call" or "moose tones".

What's a spline?

[XEROX PARC] This phrase expands to: "You have just used a term that I've heard for a year and a half, and I feel I should know, but don't. My curiosity has finally overcome my guilt." The PARC lexicon adds "Moral: don't hesitate to ask questions, even if they seem obvious."

wheel /n./

[from slang `big wheel' for a powerful person] A person who has an active wheel bit. "We need to find a wheel to unwedge the hung tape drives." (See wedged, sense 1.) The traditional name of security group zero in BSD (to which the major system-internal users like root belong) is `wheel'. Some vendors have expanded on this usage, modifying Unix so that only members of group `wheel' can go root.

wheel bit /n./

A privilege bit that allows the possessor to perform some restricted operation on a timesharing system, such as read or write any file on the system regardless of protections, change or look at any address in the running monitor, crash or reload the system, and kill or create jobs and user accounts. The term was invented on the TENEX operating system, and carried over to TOPS-20, XEROX-IFS, and others. The state of being in a privileged logon is sometimes called `wheel mode'. This term entered the Unix culture from TWENEX in the mid-1980s and has been gaining popularity there (esp. at university sites). See also root.

wheel wars /n./

[Stanford University] A period in larval stage during which student hackers hassle each other by attempting to log each other out of the system, delete each other's files, and otherwise wreak havoc, usually at the expense of the lesser users.

White Book /n./

1. Syn. K&R. 2. Adobe's fourth book in the PostScript series, describing the previously-secret format of Type 1 fonts; "Adobe Type 1 Font Format, version 1.1", (Addison-Wesley, 1990, ISBN 0-201-57044-0). See also Red Book, Green Book, Blue Book.

whizzy /adj./

(alt. `wizzy') [Sun] Describes a cuspy program; one that is feature-rich and well presented.


[UK] 1. /n.,v./ Commonly used to describe chatter, content-free remarks or other essentially meaningless contributions to threads in newsgroups. "Oh, rspence is wibbling again". Compare humma. 2. One of the preferred metasyntactic variables in the UK, forming a series with wobble, wubble, and flob (attributed to the hilarious historical comedy "Blackadder").

WIBNI // /n./

[Bell Labs: Wouldn't It Be Nice If] What most requirements documents and specifications consist entirely of. Compare IWBNI.

widget /n./

1. A meta-thing. Used to stand for a real object in didactic examples (especially database tutorials). Legend has it that the original widgets were holders for buggy whips. "But suppose the parts list for a widget has 52 entries...." 2. [poss. evoking `window gadget'] A user interface object in X graphical user interfaces.

wiggles /n./

[scientific computation] In solving partial differential equations by finite difference and similar methods, wiggles are sawtooth (up-down-up-down) oscillations at the shortest wavelength representable on the grid. If an algorithm is unstable, this is often the most unstable waveform, so it grows to dominate the solution. Alternatively, stable (though inaccurate) wiggles can be generated near a discontinuity by a Gibbs phenomenon.

WIMP environment /n./

[acronym: `Window, Icon, Menu, Pointing device (or Pull-down menu)'] A graphical-user-interface environment such as X or the Macintosh interface, esp. as described by a hacker who prefers command-line interfaces for their superior flexibility and extensibility. However, it is also used without negative connotations; one must pay attention to voice tone and other signals to interpret correctly. See menuitis, user-obsequious.


[MIT] 1. /vi./ To succeed. A program wins if no unexpected conditions arise, or (especially) if it sufficiently robust to take exceptions in stride. 2. /n./ Success, or a specific instance thereof. A pleasing outcome. "So it turned out I could use a lexer generator instead of hand-coding my own pattern recognizer. What a win!" Emphatic forms: `moby win', `super win', `hyper-win' (often used interjectively as a reply). For some reason `suitable win' is also common at MIT, usually in reference to a satisfactory solution to a problem. Oppose lose; see also big win, which isn't quite just an intensification of `win'.

win big /vi./

To experience serendipity. "I went shopping and won big; there was a 2-for-1 sale." See big win.

win win /excl./

Expresses pleasure at a win.

Winchester /n./

Informal generic term for sealed-enclosure magnetic-disk drives in which the read-write head planes over the disk surface on an air cushion. There is a legend that the name arose because the original 1973 engineering prototype for what later became the IBM 3340 featured two 30-megabyte volumes; 30--30 became `Winchester' when somebody noticed the similarity to the common term for a famous Winchester rifle (in the latter, the first 30 referred to caliber and the second to the grain weight of the charge). Others claim, however, that Winchester was simply the laboratory in which the technology was developed.

windoid /n./

In the Macintosh world, a style of window with much less adornment (smaller or missing title bar, zoom box, etc, etc) than a standard window.

window shopping /n./

[US Geological Survey] Among users of WIMP environments like X or the Macintosh, extended experimentation with new window colors, fonts, and icon shapes. This activity can take up hours of what might otherwise have been productive working time. "I spent the afternoon window shopping until I found the coolest shade of green for my active window borders -- now they perfectly match my medium slate blue background." Serious window shoppers will spend their days with bitmap editors, creating new and different icons and background patterns for all to see. Also: `window dressing', the act of applying new fonts, colors, etc. See fritterware, compare macdink.

Windoze /win'dohz/ /n./

See Microsloth Windows.

winged comments /n./

Comments set on the same line as code, as opposed to boxed comments. In C, for example:

d = sqrt(x*x + y*y);  /* distance from origin */

Generally these refer only to the action(s) taken on that line.

winkey /n./

(alt. `winkey face') See emoticon.

winnage /win'*j/ /n./

The situation when a lossage is corrected, or when something is winning.


1. /n./ An unexpectedly good situation, program, programmer, or person. 2. `real winner': Often sarcastic, but also used as high praise (see also the note under user). "He's a real winner -- never reports a bug till he can duplicate it and send in an example."

winnitude /win'*-t[y]ood/ /n./

The quality of winning (as opposed to winnage, which is the result of winning). "Guess what? They tweaked the microcode and now the LISP interpreter runs twice as fast as it used to." "That's really great! Boy, what winnitude!" "Yup. I'll probably get a half-hour's winnage on the next run of my program." Perhaps curiously, the obvious antonym `lossitude' is rare.

wired /n./

See hardwired.

wirehead /wi:r'hed/ /n./

[prob. from SF slang for an electrical-brain-stimulation addict] 1. A hardware hacker, especially one who concentrates on communications hardware. 2. An expert in local-area networks. A wirehead can be a network software wizard too, but will always have the ability to deal with network hardware, down to the smallest component. Wireheads are known for their ability to lash up an Ethernet terminator from spare resistors, for example.

wirewater /n./

Syn. programming fluid. This melds the mainstream slang adjective `wired' (stimulated, up, hyperactive) with `firewater'; however, it refers to caffeinacious rather than alcoholic beverages.

wish list /n./

A list of desired features or bug fixes that probably won't get done for a long time, usually because the person responsible for the code is too busy or can't think of a clean way to do it. "OK, I'll add automatic filename completion to the wish list for the new interface." Compare tick-list features.

within delta of /adj./

See delta.

within epsilon of /adj./

See epsilon.

wizard /n./

1. A person who knows how a complex piece of software or hardware works (that is, who groks it); esp. someone who can find and fix bugs quickly in an emergency. Someone is a hacker if he or she has general hacking ability, but is a wizard with respect to something only if he or she has specific detailed knowledge of that thing. A good hacker could become a wizard for something given the time to study it. 2. A person who is permitted to do things forbidden to ordinary people; one who has wheel privileges on a system. 3. A Unix expert, esp. a Unix systems programmer. This usage is well enough established that `Unix Wizard' is a recognized job title at some corporations and to most headhunters. See guru, lord high fixer. See also deep magic, heavy wizardry, incantation, magic, mutter, rain dance, voodoo programming, wave a dead chicken.

Wizard Book /n./

"Structure and Interpretation of Computer Programs" (Hal Abelson, Jerry Sussman and Julie Sussman; MIT Press, 1984, 1996; ISBN 0-262-01153-0), an excellent computer science text used in introductory courses at MIT. So called because of the wizard on the jacket. One of the bibles of the LISP/Scheme world. Also, less commonly, known as the Purple Book.

wizard mode /n./

[from rogue] A special access mode of a program or system, usually passworded, that permits some users godlike privileges. Generally not used for operating systems themselves (`root mode' or `wheel mode' would be used instead). This term is often used with respect to games that have editable state.

wizardly /adj./

Pertaining to wizards. A wizardly feature is one that only a wizard could understand or use properly.

wok-on-the-wall /n./

A small microwave dish antenna used for cross-campus private network circuits, from the obvious resemblance between a microwave dish and the Chinese culinary utensil.

womb box /n./

1. [TMRC] Storage space for equipment. 2. [proposed] A variety of hard-shell equipment case with heavy interior padding and/or shaped carrier cutouts in a foam-rubber matrix; mundanely called a `flight case'. Used for delicate test equipment, electronics, and musical instruments.

WOMBAT /wom'bat/ /adj./

[acronym: Waste Of Money, Brains, And Time] Applied to problems which are both profoundly uninteresting in themselves and unlikely to benefit anyone interesting even if solved. Often used in fanciful constructions such as `wrestling with a wombat'. See also crawling horror, SMOP. Also note the rather different usage as a metasyntactic variable in Commonwealth Hackish.

Users of the PDP-11 database program DATATRIEVE adopted the wombat as their notional mascot; the program's help file responded to "HELP WOMBAT" with factual information about Real World wombats.

wonky /wong'kee/ /adj./

[from Australian slang] Yet another approximate synonym for broken. Specifically connotes a malfunction that produces behavior seen as crazy, humorous, or amusingly perverse. "That was the day the printer's font logic went wonky and everybody's listings came out in Tengwar." Also in `wonked out'. See funky, demented, bozotic.

woofer /n./

[University of Waterloo] Some varieties of wide paper for printers have a perforation 8.5 inches from the left margin that allows the excess on the right-hand side to be torn off when the print format is 80 columns or less wide. The right-hand excess may be called `woofer'. This term (like tweeter) has been in use at Waterloo since 1972, but is elsewhere unknown. In audio jargon, the word refers to the bass speaker(s) on a hi-fi.

workaround /n./

1. A temporary kluge used to bypass, mask, or otherwise avoid a bug or misfeature in some system. Theoretically, workarounds are always replaced by fixes; in practice, customers often find themselves living with workarounds for long periods of time. "The code died on NUL characters in the input, so I fixed it to interpret them as spaces." "That's not a fix, that's a workaround!" 2. A procedure to be employed by the user in order to do what some currently non-working feature should do. Hypothetical example: "Using META-F7 crashes the 4.43 build of Weemax, but as a workaround you can type CTRL-R, then SHIFT-F5, and delete the remaining cruft by hand."

working as designed /adj./

[IBM] 1. In conformance to a wrong or inappropriate specification; useful, but misdesigned. 2. Frequently used as a sardonic comment on a program's utility. 3. Unfortunately also used as a bogus reason for not accepting a criticism or suggestion. At IBM, this sense is used in official documents! See BAD.

worm /n./

[from `tapeworm' in John Brunner's novel "The Shockwave Rider", via XEROX PARC] A program that propagates itself over a network, reproducing itself as it goes. Compare virus. Nowadays the term has negative connotations, as it is assumed that only crackers write worms. Perhaps the best-known example was Robert T. Morris's `Internet Worm' of 1988, a `benign' one that got out of control and hogged hundreds of Suns and VAXen across the U.S. See also cracker, RTM, Trojan horse, ice, and Great Worm, the.

wormhole /werm'hohl/ /n./

[from the `wormhole' singularities hypothesized in some versions of General Relativity theory] 1. obs.

A location in a monitor which contains the address of a routine, with the specific intent of making it easy to substitute a different routine. This term is now obsolescent; modern operating systems use clusters of wormholes extensively (for modularization of I/O handling in particular, as in the Unix device-driver organization) but the preferred techspeak for these clusters is `device tables', `jump tables' or `capability tables'. 2. [Amateur Packet Radio] A network path using a commercial satellite link to join two or more amateur VHF networks. So called because traffic routed through a wormhole leaves and re-enters the amateur network over great distances with usually little clue in the message routing header as to how it got from one relay to the other. Compare gopher hole (sense 2).

wound around the axle /adj./

In an infinite loop. Often used by older computer types.

wrap around /vi./

(also /n./ `wraparound' and /v./ shorthand `wrap') 1. [techspeak] The action of a counter that starts over at zero or at `minus infinity' (see infinity) after its maximum value has been reached, and continues incrementing, either because it is programmed to do so or because of an overflow (as when a car's odometer starts over at 0). 2. To change phase gradually and continuously by maintaining a steady wake-sleep cycle somewhat longer than 24 hours, e.g., living six long (28-hour) days in a week (or, equivalently, sleeping at the rate of 10 microhertz). This sense is also called phase-wrapping.

write-only code /n./

[a play on `read-only memory'] Code so arcane, complex, or ill-structured that it cannot be modified or even comprehended by anyone but its author, and possibly not even by him/her. A Bad Thing.

write-only language /n./

A language with syntax (or semantics) sufficiently dense and bizarre that any routine of significant size is automatically write-only code. A sobriquet applied occasionally to C and often to APL, though INTERCAL and TECO certainly deserve it more.

write-only memory /n./

The obvious antonym to `read-only memory'. Out of frustration with the long and seemingly useless chain of approvals required of component specifications, during which no actual checking seemed to occur, an engineer at Signetics once created a specification for a write-only memory and included it with a bunch of other specifications to be approved. This inclusion came to the attention of Signetics management only when regular customers started calling and asking for pricing information. Signetics published a corrected edition of the data book and requested the return of the `erroneous' ones. Later, around 1974, Signetics bought a double-page spread in "Electronics" magazine's April issue and used the spec as an April Fools' Day joke. Instead of the more conventional characteristic curves, the 25120 "fully encoded, 9046 x N, Random Access, write-only-memory" data sheet included diagrams of "bit capacity vs. Temp.", "Iff vs. Vff", "Number of pins remaining vs. number of socket insertions", and "AQL vs. selling price". The 25120 required a 6.3 VAC VFF supply, a +10V VCC, and VDD of 0V, @Math{+/-} 2%.

Wrong Thing /n./

A design, action, or decision that is clearly incorrect or inappropriate. Often capitalized; always emphasized in speech as if capitalized. The opposite of the Right Thing; more generally, anything that is not the Right Thing. In cases where `the good is the enemy of the best', the merely good -- although good -- is nevertheless the Wrong Thing. "In C, the default is for module-level declarations to be visible everywhere, rather than just within the module. This is clearly the Wrong Thing."

wugga wugga /wuh'g* wuh'g*/ /n./

Imaginary sound that a computer program makes as it labors with a tedious or difficult task. Compare cruncha cruncha cruncha, grind (sense 4).

wumpus /wuhm'p*s/ /n./

The central monster (and, in many versions, the name) of a famous family of very early computer games called "Hunt The Wumpus", dating back at least to 1972 (several years before ADVENT) on the Dartmouth Time-Sharing System. The wumpus lived somewhere in a cave with the topology of an dodecahedron's edge/vertex graph (later versions supported other topologies, including an icosahedron and Möbius strip). The player started somewhere at random in the cave with five `crooked arrows'; these could be shot through up to three connected rooms, and would kill the wumpus on a hit (later versions introduced the wounded wumpus, which got very angry). Unfortunately for players, the movement necessary to map the maze was made hazardous not merely by the wumpus (which would eat you if you stepped on him) but also by bottomless pits and colonies of super bats that would pick you up and drop you at a random location (later versions added `anaerobic termites' that ate arrows, bat migrations, and earthquakes that randomly changed pit locations).

This game appears to have been the first to use a non-random graph-structured map (as opposed to a rectangular grid like the even older Star Trek games). In this respect, as in the dungeon-like setting and its terse, amusing messages, it prefigured ADVENT and Zork and was directly ancestral to the latter (Zork acknowledged this heritage by including a super-bat colony). Today, a port is distributed with SunOS and as freeware for the Mac. A C emulation of the original Basic game is available at the Retrocomputing Museum, http://www.ccil.org/retro.

WYSIAYG /wiz'ee-ayg/ /adj./

Describes a user interface under which "What You See Is All You Get"; an unhappy variant of WYSIWYG. Visual, `point-and-shoot'-style interfaces tend to have easy initial learning curves, but also to lack depth; they often frustrate advanced users who would be better served by a command-style interface. When this happens, the frustrated user has a WYSIAYG problem. This term is most often used of editors, word processors, and document formatting programs. WYSIWYG `desktop publishing' programs, for example, are a clear win for creating small documents with lots of fonts and graphics in them, especially things like newsletters and presentation slides. When typesetting book-length manuscripts, on the other hand, scale changes the nature of the task; one quickly runs into WYSIAYG limitations, and the increased power and flexibility of a command-driven formatter like TeX or Unix's troff becomes not just desirable but a necessity. Compare YAFIYGI.

WYSIWYG /wiz'ee-wig/ /adj./

Describes a user interface under which "What You See Is What You Get", as opposed to one that uses more-or-less obscure commands that do not result in immediate visual feedback. True WYSIWYG in environments supporting multiple fonts or graphics is a a rarely-attained ideal; there are variants of this term to express real-world manifestations including WYSIAWYG (What You See Is Almost What You Get) and WYSIMOLWYG (What You See Is More or Less What You Get). All these can be mildly derogatory, as they are often used to refer to dumbed-down user-friendly interfaces targeted at non-programmers; a hacker has no fear of obscure commands (compare WYSIAYG). On the other hand, EMACS was one of the very first WYSIWYG editors, replacing (actually, at first overlaying) the extremely obscure, command-based TECO. See also WIMP environment. [Oddly enough, WYSIWYG has already made it into the OED, in lower case yet. --ESR]
