         n. [common] A collection of arcane, unpublished, and (by implication) mostly ad-hoc techniques developed for a particular application or systems area (compare black magic ). VLSI design and compiler code optimization were (in their beginnings) considered classic examples of black art; as theory developed they became deep magic , and once standard textbooks had been written, became merely heavy wizardry. The huge proliferation of formal and informal channels for spreading around new computer-related technologies during the last twenty years has made both the term black art and what it describes less common than formerly. See also voodoo programming.

         n.,vt. [common] What data (a piece of email or netnews, or a stream of TCP/IP packets) has fallen into if it disappears mysteriously between its origin and destination sites (that is, without returning a bounce message ). I think there's a black hole at foovax ! conveys suspicion that site foovax has been dropping a lot of stuff on the floor lately (see drop on the floor ). The implied metaphor of email as interstellar travel is interesting in itself.
