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."

   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.)
