:crufty: /kruhf'tee/ [origin unknown; poss. from `crusty' or `cruddy'] adj. 1. Poorly built, possibly over-complex. The {canonical} example is "This is standard old crufty DEC software". In fact, one fanciful theory of the origin of `crufty' holds that was originally a mutation of `crusty' applied to DEC software so old that the `s' characters were tall and skinny, looking more like `f' characters. 2. Unpleasant, especially to the touch, often with encrusted junk. Like spilled coffee smeared with peanut butter and catsup. 3. Generally unpleasant. 4. (sometimes spelled `cruftie') n. A small crufty object (see {frob}); often one that doesn't fit well into the scheme of things. "A LISP property list is a good place to store crufties (or, collectively, {random} cruft)."
:crumb: n. Two binary digits; a {quad}. Larger than a {bit}, smaller than a {nybble}. Considered silly. Syn. {tayste}.
:crunch: 1. vi. To process, usually in a time-consuming or complicated way. Connotes an essentially trivial operation that is nonetheless painful to perform. The pain may be due to the triviality's being embedded in a loop from 1 to 1,000,000,000. "FORTRAN programs do mostly {number-crunching}." 2. vt. To reduce the size of a file by a complicated scheme that produces bit configurations completely unrelated to the original data, such as by a Huffman code. (The file ends up looking like a paper document would if somebody crunched the paper into a wad.) Since such compression usually takes more computations than simpler methods such as run-length encoding, the term is doubly appropriate. (This meaning is usually used in the construction `file crunch(ing)' to distinguish it from {number-crunching}.) See {compress}. 3. n. The character `#'. Used at XEROX and CMU, among other places. See {{ASCII}}. 4. vt. To squeeze program source into a minimum-size representation that will still compile or execute. The term came into being specifically for a famous program on the BBC micro that crunched BASIC source in order to make it run more quickly (it was a wholly interpretive BASIC, so the number of characters mattered). {Obfuscated C Contest} entries are often crunched; see the first example under that entry.
:cruncha cruncha cruncha: /kruhn'ch* kruhn'ch* kruhn'ch*/ interj. An encouragement sometimes muttered to a machine bogged down in a serious {grovel}. Also describes a notional sound made by groveling hardware. See {wugga wugga}, {grind} (sense 3).
:cryppie: /krip'ee/ n. A cryptographer. One who hacks or implements cryptographic software or hardware.
:CTSS: /C-T-S-S/ n. Compatible Time-Sharing System. An early (1963) experiment in the design of interactive time-sharing operating systems, ancestral to {{Multics}}, {{UNIX}}, and {{ITS}}. The name {{ITS}} (Incompatible Time-sharing System) was a hack on CTSS, meant both as a joke and to express some basic differences in philosophy about the way I/O services should be presented to user programs.
:CTY: /sit'ee/ or /C-T-Y/ n. [MIT] The terminal physically associated with a computer's system {{console}}. The term is a contraction of `Console {tty}', that is, `Console TeleTYpe'. This {{ITS}}- and {{TOPS-10}}-associated term has become less common, as most UNIX hackers simply refer to the CTY as `the console'.
:cube: n. 1. [short for `cubicle'] A module in the open-plan offices used at many programming shops. "I've got the manuals in my cube." 2. A NeXT machine (which resembles a matte-black cube).
:cubing: [parallel with `tubing'] vi. 1. Hacking on an IPSC (Intel Personal SuperComputer) hypercube. "Louella's gone cubing *again*!!" 2. Hacking Rubik's Cube or related puzzles, either physically or mathematically. 3. An indescribable form of self-torture (see sense 1 or 2).
:cursor dipped in X: n. There are a couple of metaphors in English
of the form `pen dipped in X' (perhaps the most common values of X
are `acid', `bile', and `vitriol'). These map over neatly to this
hackish usage (the cursor being what moves, leaving letters behind,
when one is composing on-line). "Talk about a {nastygram}! He
must've had his cursor dipped in acid when he wrote that one!"
