: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 offense.
: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 flavor 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.
:warlording: [from the USENET group alt.fan.warlord] v. 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 quote}s, ugly {ASCII art}, or simply excessive size. The original `Warlord' was a {BIFF}-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, {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}.
