n 1: (thermodynamics) a thermodynamic quantity representing the
amount of energy in a system that is no longer available
for doing mechanical work; "entropy increases as matter and
energy in the universe degrade to an ultimate state of
inert uniformity" [syn: randomness, entropy, S]
2: the quality of lacking any predictable order or plan [syn:
randomness, haphazardness, stochasticity, noise] |
randomness
(foldoc) | 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."

Despite the negative connotations of most jargon uses of this term have, it
is worth noting that randomness can actually be a valuable resource, very
useful for applications in cryptography and elsewhere. Computers are so
thoroughly deterministic that they have a hard time generating high-quality
randomness, so hackers have sometimes felt the need to built
special-purpose contraptions for this purpose alone. One well-known website
offers random bits generated by radioactive decay. Another derives random
bits from chaotic systems in analog electronics. Originally, the latter
site got its random bits by doing photometry on lava lamps. Hackers
invariably found this hilarious. If you have to ask why, you'll never get
it.)
