  1. compact

    In mathematics, particularly in topology, a set is called compact if it has the property that every open cover has a finite subcover. Specifically, a topological space or a set is said to be compact if from any arbitrary collection of open sets that covers the set or the space, a finite number of open sets can be selected that also covers the set or the space. This concept plays a significant role in areas such as real analysis, complex analysis, and general topology.

The New Hacker's Dictionary

  1. compact

    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 features 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).
