compact
adj. Of a design, describes the valuable property that it can all be apprehended at once in one's head. This generally means the thing created from the design can be used with greater facility and fewer errors than an equivalent tool that is not compact. Compactness does not imply triviality or lack of power; for example, C is compact and FORTRAN is not, but C is more powerful than FORTRAN. Designs become non-compact through accreting {feature}s and {cruft} that don't merge cleanly into the overall design scheme (thus, some fans of {Classic C} maintain that ANSI C is no longer compact).
compiler jock
n. See {jock} (sense 2).
compress
[UNIX] vt. When used without a qualifier, generally refers to {crunch}ing of a file using a particular C implementation of compression by James A. Woods et al. and widely circulated via {USENET}; use of {crunch} itself in this sense is rare among UNIX hackers. Specifically, compress is built around the Lempel-Ziv-Welch algorithm as described in "A Technique for High Performance Data Compression", Terry A. Welch, `IEEE Computer', vol. 17, no. 6 (June 1984), pp. 8-19.
