wabbit: /wab'it/ [almost certainly from Elmer Fudd's immortal line "You wascawwy wabbit!"] n.
   1. A legendary early hack reported on a System/360 at RPI and elsewhere around 1978. 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 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 commandswere 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.
   {Bucky bits} were also invented there --- 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/ [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
   meta-syntactic 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 machine}s.  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

wall: [WPI] interj. 1. An indication of confusion, usually spoken with a quizzical tone:
   "Wall??"  2. A request for further explication.  Compare {octal forty}. It is said that
   "Wall?" really came from `like talking to a blank wall'.  It was initially 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}, {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 {clocks} required to execute it (on a timesharing system these will
   differ, as no one program gets all the {clocks}, and on multiprocessor systems with good
   thread support one may get more processor clocks than real-time clocks).

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 {grovel}ling 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/ [Columbia University: prob. by mutation from Commonwealth slang v. `wank', to
   masturbate] n.,v. 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

wannabee: /won'*-bee/ (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] n. 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 flavour now (1991) 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.

warm boot: n. See {boot}.

wart: n. A small, {crock}y {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 obtaining ASCII characters in a foreign
   environment is a wart.  See also {miswart}.

washing machine: n. 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}).

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 na"ive user, one who deliberately or accidentally does things that
   are stupid or ill-advised.  Roughly synonymous with {loser}.

wedged: [from a common description of recto-cranial inversion] adj. 1. To be stuck, incapable
   of proceeding without help.  This is different from having crashed. If the system has
   crashed, then 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 {deadlock}s with
   another (but not all instances of wedging are deadlocks).  Being wedged is slightly milder
   than being {hung}.  See also {gronk}, {locked up}, {hosed}.  Describes a {deadlock}ed
   condition.  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.

wedgie: [Fairchild] n. A bug.  Prob. related to {wedged}.

wedgitude: /wedj'i-t[y]ood/ n. The quality or state of being {wedged}.

weeble: /weeb'l/ [Cambridge] interj. 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. 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 positive or negative depends on
   the hearer's judgment of how the speaker feels about that area. See also {bigot}.  2. The
   semicolon character, `;' (ASCII 0111011).

Weenix: /wee'niks/ [ITS] n. 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, this means 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/ [prob. from the novels of Rudy Rucker] n. 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}.

whacker: [University of Maryland: from {hacker}] n. 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}.

wheel: [from slang `big wheel' for a powerful person] n. A person who has an active a {wheel
   bit}.  "We need to find a  wheel to un{wedge} the hung tape drives."

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: [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. Syn. {K&R}.

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

WIBNI: // [Bell Labs: Wouldn't It Be Nice If] n. 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. [acronymic from `Window, Icon, Menu, Pointing device (or Pull-down menu)']
   A graphical-user-interface-based environment such as {X} or the Macintosh interface, as
   described by a hacker who prefers command-line interfaces for their superior flexibility
   and extensibility.  See {menuitis}, {user-obsequious}.

win: [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.  A {feature}.  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: interj. Expresses pleasure at a {win}.

Winchester:: n. Informal generic term for `floating-head' magnetic-disk drives in which the
   read-write head planes over the disk surface on an air cushion. 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).

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.

winner: 1. n. An unexpectedly good situation, program, programmer, or person. "So it turned
   out I could use a {lexer} generator instead of hand-coding my own pattern recognizer. What
   a win!" 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

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 {grok}s 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. Hal Abelson and Jerry Sussman's `Structure and Interpretation of Computer
   Programs' (MIT Press, 1984; ISBN 0-262-01077-1, an excellent computer science text used in
   introductory courses at MIT.  So called because of the wizard on the jacket.  One of the
   {bible}s of the LISP/Scheme world.

wizard mode: [from {rogue}] n. 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).

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

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: [Waste Of Money, Brains, And Time] adj. 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 meta-syntactic variable in
   {{Commonwealth Hackish}}.

wonky: /wong'kee/ [from Australian slang] adj. Yet another approximate synonym for {broken}.
   Specifically connotes a malfunction that produces behavior seen as crazy, humourous, 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}.

workaround: n. A temporary {kluge} inserted in a system under development or test in order to
   avoid the effects of a {bug} or {misfeature} so that work can continue.  Theoretically,
   workarounds are always replaced by {fix}es; in practice, customers often find themselves
   living with workarounds in the first couple of releases.  "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

working as designed: [IBM] adj. 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: [from `tapeworm' in John Brunner's novel `The Shockwave Rider', via XEROX PARC] n. 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
   {cracker}s 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}.

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).

write-only code: [a play on `read-only memory'] n. 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 {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, +/- 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 labours
   with a tedious or difficult task. Compare {cruncha cruncha cruncha}, {grind} (sense 4).

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 which do not result in
   immediate visual feedback.  The term can be mildly derogatory, as it is often used to refer
   to dumbed-down {user-friendly} interfaces targeted at non-programmers; a hacker has no fear
   of obscure commands. 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, this term has already made it into the OED. --- ESR]
