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