random: adj. 1. Unpredictable (closest to mathematical
   definition); weird.  "The system's been behaving pretty
   randomly."  2. Assorted; undistinguished.  "Who was at the
   conference?"  "Just a bunch of random business types."
   3. (pejorative) Frivolous; unproductive; undirected.  "He's just a
   random loser."  4. Incoherent or inelegant; poorly chosen; not
   well organized.  "The program has a random set of misfeatures."
   "That's a random name for that function."  "Well, all the names
   were chosen pretty randomly."  5. In no particular order, though
   deterministic.  "The I/O channels are in a pool, and when a file
   is opened one is chosen randomly."  6. Arbitrary.  "It generates
   a random name for the scratch file."  7. Gratuitously wrong, i.e.,
   poorly done and for no good apparent reason.  For example, a
   program that handles file name defaulting in a particularly useless
   way, or an assembler routine that could easily have been coded
   using only three registers, but redundantly uses seven for values
   with non-overlapping lifetimes, so that no one else can invoke it
   without first saving four extra registers.  What randomness!
   8. n. A random hacker; used particularly of high-school students
   who soak up computer time and generally get in the way.  9. n.
   Anyone who is not a hacker (or, sometimes, anyone not known to the
   hacker speaking); the noun form of sense 2.  "I went to the talk,
   but the audience was full of randoms asking bogus questions".
   10. n. (occasional MIT usage) One who lives at Random Hall.  See
   also J. Random, some random X.
