out}, usually the preferred technique in languages (such as {C}) that make it possible.
:Commonwealth Hackish:: n. Hacker jargon as spoken outside the U.S., esp. in the British Commonwealth. It is reported that Commonwealth speakers are more likely to pronounce truncations like `char' and `soc', etc., as spelled (/char/, /sok/), as opposed to American /keir/ and /sohsh/. Dots in {newsgroup} names tend to be pronounced more often (so soc.wibble is /sok dot wib'l/ rather than /sohsh wib'l/). The prefix {meta} may be pronounced /mee't*/; similarly, Greek letter beta is often /bee't*/, zeta is often /zee't*/, and so forth. Preferred {metasyntactic variable}s include {blurgle}, `eek', `ook', `frodo', and `bilbo'; `wibble', `wobble', and in emergencies `wubble'; `banana', `wombat', `frog', {fish}, and so on and on (see {foo}, sense 4).
Alternatives to verb doubling include suffixes `-o-rama', `frenzy' (as in feeding frenzy), and `city' (examples: "barf city!" "hack-o-rama!" "core dump frenzy!"). Finally, note that the American terms `parens', `brackets', and `braces' for (), [], and {} are uncommon; Commonwealth hackish prefers `brackets', `square brackets', and `curly brackets'. Also, the use of `pling' for {bang} is common outside the United States.

:compact: adj. Of a design, describes the valuable property that it can all be apprehended at once in one's head. This generally means the thing created from the design can be used with greater facility and fewer errors than an equivalent tool that is not compact. Compactness does not imply triviality or lack of power; for example, C is compact and FORTRAN is not, but C is more powerful than FORTRAN. Designs become non-compact through accreting {feature}s and {cruft} that don't merge cleanly into the overall design scheme (thus, some fans of {Classic C} maintain that ANSI C is no longer compact).
:compiler jock: n. See {jock} (sense 2).
:compress: [UNIX] vt. When used without a qualifier, generally refers to {crunch}ing of a file using a particular C implementation of compression by James A. Woods et al. and widely circulated via {USENET}; use of {crunch} itself in this sense is rare among UNIX hackers. Specifically, compress is built around the Lempel-Ziv-Welch algorithm as described in "A Technique for High Performance Data Compression", Terry A. Welch, `IEEE Computer', vol. 17, no. 6 (June 1984), pp. 8-19.
:Compu$erve: n. See {CI$}. The synonyms CompuSpend and
Compu$pend are also reported.
:computer confetti: n. Syn. {chad}. Though this term is common, this use of punched-card chad is not a good idea, as the pieces are stiff and have sharp corners that could injure the eyes. GLS reports that he once attended a wedding at MIT during which he and a few other guests enthusiastically threw chad instead of rice. The groom later grumbled that he and his bride had spent most of the evening trying to get the stuff out of their hair.
:computer geek: n. One who eats (computer) bugs for a living. One who fulfills all the dreariest negative stereotypes about hackers: an asocial, malodorous, pasty-faced monomaniac with all the personality of a cheese grater. Cannot be used by outsiders without implied insult to all hackers; compare black-on-black usage of `nigger'. A computer geek may be either a fundamentally clueless individual or a proto-hacker in {larval stage}. Also called `turbo nerd', `turbo geek'. See also {propeller head}, {clustergeeking}, {geek out}, {wannabee}, {terminal junkie}, {spod}, {weenie}.
:computron: /kom'pyoo-tron`/ n. 1. A notional unit of computing power combining instruction speed and storage capacity, dimensioned roughly in instructions-per-second times megabytes-of-main-store times megabytes-of-mass-storage. "That machine can't run GNU EMACS, it doesn't have enough computrons!" This usage is usually found in metaphors that treat computing power as a fungible commodity good, like a crop yield or diesel horsepower. See {bitty box}, {Get a real computer!}, {toy}, {crank}. 2. A mythical subatomic particle that bears the unit quantity of computation or information, in much the same way that an electron bears one unit of electric charge (see also {bogon}). An elaborate pseudo-scientific theory of computrons has been developed based on the physical fact that the molecules in a solid object move more rapidly as it is heated. It is argued that an object melts because the molecules have lost their information about where they are supposed to be (that is, they have emitted computrons). This explains why computers get so hot and require air conditioning; they use up computrons. Conversely, it should be possible to cool down an object by placing it in the path of a computron beam. It is believed that this may also explain why machines that work at the factory fail in the computer room: the computrons there have been all used up by the other hardware. (This theory probably owes something to the "Warlock" stories by Larry Niven, the best known being "What Good is a Glass Dagger?", in which magic is fueled by an exhaustible natural resource called `mana'.)
:condition out: vt. To prevent a section of code from being compiled by surrounding it with a conditional-compilation directive whose condition is always false. The {canonical} examples are `#if 0' (or `#ifdef notdef', though some find this {bletcherous}) and `#endif' in C. Compare {comment out}.
:condom: n. 1. The protective plastic bag that accompanies 3.5-inch microfloppy diskettes. Rarely, also used of (paper) disk envelopes. Unlike the write protect tab, the condom (when left on) not only impedes the practice of {SEX} but has also been shown to have a high failure rate as drive mechanisms attempt to access the disk —- and can even fatally frustrate insertion. 2. The protective cladding on a {light pipe}.
:confuser: n. Common soundalike slang for `computer'. Usually encountered in compounds such as `confuser room', `personal confuser', `confuser guru'. Usage: silly.
:connector conspiracy: [probably came into prominence with the appearance of the KL-10 (one model of the {PDP-10}), none of whose connectors matched anything else] n. The tendency of manufacturers (or, by extension, programmers or purveyors of anything) to come up with new products that don't fit together with the old stuff, thereby making you buy either all new stuff or expensive interface devices. The KL-10 Massbus connector was actually *patented* by DEC, which reputedly refused to license the design and thus effectively locked third parties out of competition for the lucrative Massbus peripherals market. This is a source of never-ending frustration for the diehards who maintain older PDP-10 or VAX systems. Their CPUs work fine, but they are stuck with dying, obsolescent disk and tape drives with low capacity and high power requirements.
(A closely related phenomenon, with a slightly different intent, is the habit manufacturers have of inventing new screw heads so that only Designated Persons, possessing the magic screwdrivers, can remove covers and make repairs or install options. The Apple Macintosh takes this one step further, requiring not only a hex wrench but a specialized case-cracking tool to open the box.)
In these latter days of open-systems computing this term has fallen
somewhat into disuse, to be replaced by the observation that
"Standards are great! There are so *many* of them to choose
from!" Compare {backward combatability}.
:cons: /konz/ or /kons/ [from LISP] 1. vt. To add a new element to a specified list, esp. at the top. "OK, cons picking a replacement for the console TTY onto the agenda." 2. `cons up': vt. To synthesize from smaller pieces: "to cons up an example".
In LISP itself, `cons' is the most fundamental operation for building structures. It takes any two objects and returns a `dot-pair' or two-branched
