From WordNet (r) 3.0 (2006) :

  randomness
      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]

From The Jargon File (version 4.4.7, 29 Dec 2003) :

  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.)

     2. A hack or crock that depends on a complex combination
     of coincidences (or, possibly, the combination upon which the

     "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!"
