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- ing. 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 something like a paper document would if somebody ed 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 (ing) to distinguish it from number- ing. ) 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 ed 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 ed; see the first example under that entry. 5. Pseudonym of John Draper, an early hacker and phreaker. See phreaking. 6. Lowest common denominator intensification of labor strategy. A phase of (typically though not exclusively) commercial software development when hackers are threatened by their project managers in order to work additional unpaid hours to meet some arbitrary deadline decided by a suit on a golf course. "I won't be at the hackspace tonight because there's a crunch on at work".
