Word Origin & History

random 
"having no definite aim or purpose," 1655, from at random (1565), "at great speed" (thus, "carelessly, haphazardly"), alteration of M.E. randon "impetuosity, speed" (c.1305), from O.Fr. randon "rush, disorder, force, impetuosity," from randir "to run fast," from Frankish *rant "a running," from P.Gmc. *randa (cf. O.H.G. rennen "to run," O.E. rinnan "to flow, to run"). In 1980s college student slang, it began to acquire a sense of "inferior, undesirable." Random access in ref. to computer memory is recorded from 1953.

Computing Dictionary

randomness
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."
[The Jargon File]
