randomness (1)An inexplicable misfeature; gratuitous inelegance.randomness (2)A hack or crock that depends on a complex combinationof coincidences (or, possibly, the combination upon which thecrock depends for its accidental failure to malfunction)."This hack can output characters 40--57 by putting thecharacter in the four bit accumulator field of an XCT and thenextracting six bits - the low 2 bits of the XCT opcode arethe right thing." "What randomness!"randomness (3)Of people, synonymous with "flakiness". The connotation isthat the person so described is behaving weirdly,incompetently, or inappropriately for reasons which are (a)too tiresome to bother inquiring into, (b) are probably asinscrutable as quantum phenomena anyway, and (c) are likely topass with time. "Maybe he has a real complaint, or maybe it'sjust randomness. See if he calls back."randomness
