:cuspy: /kuhs'pee/ [WPI: from the DEC abbreviation CUSP, for `Commonly
Used System Program', i.e., a utility program used by many people]
adj. 1. (of a program) Well-written. 2. Functionally excellent. A
program that performs well and interfaces well to users is cuspy.
See {rude}. 3. [NYU] Said of an attractive woman, especially one
regarded as available. Implies a certain curvaceousness.
:cut a tape: vi. To write a software or document distribution on magnetic tape for shipment. Has nothing to do with physically cutting the medium! Early versions of this lexicon claimed that one never analogously speaks of `cutting a disk', but this has since been reported as live usage. Related slang usages are mainstream business's `cut a check', the recording industry's `cut a record', and the military's `cut an order'.
All of these usages reflect physical processes in obsolete recording and duplication technologies. The first stage in manufacturing an old-style vinyl record involved cutting grooves in a stamping die with a precision lathe. More mundanely, the dominant technology for mass duplication of paper documents in pre-photocopying days involved "cutting a stencil", punching away portions of the wax overlay on a silk screen. More directly, paper tape with holes punched in it was an inportant early storage medium.
:cybercrud: /si:'ber-kruhd/ [coined by Ted Nelson] n. Obfuscatory tech-talk. Verbiage with a high {MEGO} factor. The computer equivalent of bureaucratese.
:cyberpunk: /si:'ber-puhnk/ [orig. by SF writer Bruce Bethke and/or editor Gardner Dozois] n.,adj. A subgenre of SF launched in 1982 by William Gibson's epoch-making novel `Neuromancer' (though its roots go back through Vernor Vinge's `True Names' (see "{True Names … and Other Dangers}" in appendix C) to John Brunner's 1975 novel `The Shockwave Rider'). Gibson's near-total ignorance of computers and the present-day hacker culture enabled him to speculate about the role of computers and hackers in the future in ways hackers have since found both irritatingly na"ive and tremendously stimulating. Gibson's work was widely imitated, in particular by the short-lived but innovative "Max Headroom" TV series. See {cyberspace}, {ice}, {jack in}, {go flatline}.
:cyberspace: /si:'ber-spays/ n. 1. Notional `information-space' loaded with visual cues and navigable with brain-computer interfaces called `cyberspace decks'; a characteristic prop of {cyberpunk} SF. At the time of this writing (mid-1991), serious efforts to construct {virtual reality} interfaces modeled explicitly on Gibsonian cyberspace are already under way, using more conventional devices such as glove sensors and binocular TV headsets. Few hackers are prepared to deny outright the possibility of a cyberspace someday evolving out of the network (see {network, the}). 2. Occasionally, the metaphoric location of the mind of a person in {hack mode}. Some hackers report experiencing strong eidetic imagery when in hack mode; interestingly, independent reports from multiple sources suggest that there are common features to the experience. In particular, the dominant colors of this subjective `cyberspace' are often gray and silver, and the imagery often involves constellations of marching dots, elaborate shifting patterns of lines and angles, or moire patterns.
:cycle: 1. n. The basic unit of computation. What every hacker wants more of (noted hacker Bill Gosper describes himself as a "cycle junkie"). One can describe an instruction as taking so many `clock cycles'. Often the computer can access its memory once on every clock cycle, and so one speaks also of `memory cycles'. These are technical meanings of {cycle}. The jargon meaning comes from the observation that there are only so many cycles per second, and when you are sharing a computer the cycles get divided up among the users. The more cycles the computer spends working on your program rather than someone else's, the faster your program will run. That's why every hacker wants more cycles: so he can spend less time waiting for the computer to respond. 2. By extension, a notional unit of *human* thought power, emphasizing that lots of things compete for the typical hacker's think time. "I refused to get involved with the Rubik's Cube back when it was big. Knew I'd burn too many cycles on it if I let myself." 3. vt. Syn. {bounce}, {120 reset}; from the phrase `cycle power'. "Cycle the machine again, that serial port's still hung."
:cycle crunch: n. A situation where the number of people trying to use the computer simultaneously has reached the point where no one can get enough cycles because they are spread too thin and the system has probably begun to {thrash}. This is an inevitable result of Parkinson's Law applied to timesharing. Usually the only solution is to buy more computer. Happily, this has rapidly become easier in recent years, so much so that the very term `cycle crunch' now has a faintly archaic flavor; most hackers now use workstations or personal computers as opposed to traditional timesharing systems.
:cycle drought: n. A scarcity of cycles. It may be due to a {cycle crunch}, but it could also occur because part of the computer is temporarily not working, leaving fewer cycles to go around. "The {high moby} is {down}, so we're running with only half the usual amount of memory. There will be a cycle drought until it's fixed."
:cycle of reincarnation: [coined by Ivan Sutherland ca. 1970] n. Term used to refer to a well-known effect whereby function in a computing system family is migrated out to special-purpose peripheral hardware for speed, then the peripheral evolves toward more computing power as it does its job, then somebody notices that it is inefficient to support two asymmetrical processors in the architecture and folds the function back into the main CPU, at which point the cycle begins again. Several iterations of this cycle have been observed in graphics-processor design, and at least one or two in communications and floating-point processors. Also known as `the Wheel of Life', `the Wheel of Samsara', and other variations of the basic Hindu/Buddhist theological idea.
