:cray instability: /n./ 1. A shortcoming of a program or algorithm that manifests itself only when a large problem is being run on a powerful machine (see {cray}). Generally more subtle than bugs that can be detected in smaller problems running on a workstation or mini. 2. More specifically, a shortcoming of algorithms which are well behaved when run on gentle floating point hardware (such as IEEE-standard or DEC) but which break down badly when exposed to a Cray's unique `rounding' rules.
:crayola: /kray-oh'l*/ /n./ A super-mini or -micro computer that provides some reasonable percentage of supercomputer performance for an unreasonably low price. Might also be a {killer micro}.
:crayola books: /n./ The {rainbow series} of National Computer Security Center (NCSC) computer security standards (see {Orange Book}). Usage: humorous and/or disparaging.
:crayon: /n./ 1. Someone who works on Cray supercomputers.
More specifically, it implies a programmer, probably of the CDC
ilk, probably male, and almost certainly wearing a tie
(irrespective of gender). Systems types who have a Unix background
tend not to be described as crayons. 2. A {computron} (sense 2)
that participates only in {number-crunching}. 3. A unit of
computational power equal to that of a single Cray-1. There is a
standard joke about this usage that derives from an old Crayola
crayon promotional gimmick: When you buy 64 crayons you get a free
sharpener.
:creationism: /n./ The (false) belief that large, innovative
software designs can be completely specified in advance and then
painlessly magicked out of the void by the normal efforts of a team
of normally talented programmers. In fact, experience has shown
repeatedly that good designs arise only from evolutionary,
exploratory interaction between one (or at most a small handful of)
exceptionally able designer(s) and an active user population —-
and that the first try at a big new idea is always wrong.
Unfortunately, because these truths don't fit the planning models
beloved of {management}, they are generally ignored.
:creep: /v./ To advance, grow, or multiply inexorably. In hackish usage this verb has overtones of menace and silliness, evoking the creeping horrors of low-budget monster movies.
:creeping elegance: /n./ Describes a tendency for parts of a design to become {elegant} past the point of diminishing return, something which often happens at the expense of the less interesting parts of the design, the schedule, and other things deemed important in the {Real World}. See also {creeping featurism}, {second-system effect}, {tense}.
:creeping featurism: /kree'ping fee'chr-izm/ /n./ 1. Describes a systematic tendency to load more {chrome} and {feature}s onto systems at the expense of whatever elegance they may have possessed when originally designed. See also {feeping creaturism}. "You know, the main problem with {BSD} Unix has always been creeping featurism." 2. More generally, the tendency for anything complicated to become even more complicated because people keep saying "Gee, it would be even better if it had this feature too". (See {feature}.) The result is usually a patchwork because it grew one ad-hoc step at a time, rather than being planned. Planning is a lot of work, but it's easy to add just one extra little feature to help someone … and then another … and another…. When creeping featurism gets out of hand, it's like a cancer. Usually this term is used to describe computer programs, but it could also be said of the federal government, the IRS 1040 form, and new cars. A similar phenomenon sometimes afflicts conscious redesigns; see {second-system effect}. See also {creeping elegance}.
:creeping featuritis: /kree'ping fee'-chr-i:`t*s/ /n./ Variant of {creeping featurism}, with its own spoonerization: `feeping creaturitis'. Some people like to reserve this form for the disease as it actually manifests in software or hardware, as opposed to the lurking general tendency in designers' minds. (After all, -ism means `condition' or `pursuit of', whereas -itis usually means `inflammation of'.)
:cretin: /kret'in/ or /kree'tn/ /n./ Congenital {loser}; an obnoxious person; someone who can't do anything right. It has been observed that many American hackers tend to favor the British pronunciation /kret'in/ over standard American /kree'tn/; it is thought this may be due to the insidious phonetic influence of Monty Python's Flying Circus.
