:gang bang: n. The use of large numbers of loosely coupled programmers in an attempt to wedge a great many features into a product in a short time. Though there have been memorable gang bangs (e.g., that over-the-weekend assembler port mentioned in Steven Levy's `Hackers'), most are perpetrated by large companies trying to meet deadlines and produce enormous buggy masses of code entirely lacking in {orthogonal}ity. When market-driven managers make a list of all the features the competition has and assign one programmer to implement each, they often miss the importance of maintaining a coherent design. See also {firefighting}, {Mongolian Hordes technique}, {Conway's Law}.

:garbage collect: vi. (also `garbage collection', n.) See {GC}.

:garply: /gar'plee/ [Stanford] n. Another metasyntactic variable (see {foo}); once popular among SAIL hackers.

:gas: [as in `gas chamber'] 1. interj. A term of disgust and hatred, implying that gas should be dispensed in generous quantities, thereby exterminating the source of irritation. "Some loser just reloaded the system for no reason! Gas!" 2. interj. A suggestion that someone or something ought to be flushed out of mercy. "The system's getting {wedged} every few minutes. Gas!" 3. vt. To {flush} (sense 1). "You should gas that old crufty software." 4. [IBM] n. Dead space in nonsequentially organized files that was occupied by data that has been deleted; the compression operation that removes it is called `degassing' (by analogy, perhaps, with the use of the same term in vacuum technology). 5. [IBM] n. Empty space on a disk that has been clandestinely allocated against future need.

:gaseous: adj. Deserving of being {gas}sed. Disseminated by Geoff Goodfellow while at SRI; became particularly popular after the Moscone-Milk killings in San Francisco, when it was learned that the defendant Dan White (a politician who had supported Proposition 7) would get the gas chamber under Proposition 7 if convicted of first-degree murder (he was eventually convicted of manslaughter).

:GC: /G-C/ [from LISP terminology; `Garbage Collect'] 1. vt. To clean up and throw away useless things. "I think I'll GC the top of my desk today." When said of files, this is equivalent to {GFR}. 2. vt. To recycle, reclaim, or put to another use. 3. n. An instantiation of the garbage collector process.

`Garbage collection' is computer-science jargon for a particular class of strategies for dynamically reallocating computer memory. One such strategy involves periodically scanning all the data in memory and determining what is no longer accessible; useless data items are then discarded so that the memory they occupy can be recycled and used for another purpose. Implementations of the LISP language usually use garbage collection.

In jargon, the full phrase is sometimes heard but the {abbrev} is more frequently used because it is shorter. Note that there is an ambiguity in usage that has to be resolved by context: "I'm going to garbage-collect my desk" usually means to clean out the drawers, but it could also mean to throw away or recycle the desk itself.

:GCOS:: /jee'kohs/ n. A {quick-and-dirty} {clone} of System/360 DOS that emerged from GE around 1970; originally called GECOS (the General Electric Comprehensive Operating System). Later kluged to support primitive timesharing and transaction processing. After the buyout of GE's computer division by Honeywell, the name was changed to General Comprehensive Operating System (GCOS). Other OS groups at Honeywell began referring to it as `God's Chosen Operating System', allegedly in reaction to the GCOS crowd's uninformed and snotty attitude about the superiority of their product. All this might be of zero interest, except for two facts: (1) The GCOS people won the political war, and this led in the orphaning and eventual death of Honeywell {{Multics}}, and (2) GECOS/GCOS left one permanent mark on UNIX. Some early UNIX systems at Bell Labs used GCOS machines for print spooling and various other services; the field added to `/etc/passwd' to carry GCOS ID information was called the `GECOS field' and survives today as the `pw_gecos' member used for the user's full name and other human-ID information. GCOS later played a major role in keeping Honeywell a dismal also-ran in the mainframe market, and was itself ditched for UNIX in the late 1980s when Honeywell retired its aging {big iron} designs.

:GECOS:: /jee'kohs/ n. See {{GCOS}}.
