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 organised.
"The program has a random set of misfeatures." "That's a
random name for that function." "Well, all the names were
chosen pretty randomly."
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. A random hacker; used particularly of high-school students
who soak up computer time and generally get in the way.
9. Anyone who is not a hacker (or, sometimes, anyone not
known to the hacker speaking). "I went to the talk, but the
audience was full of randoms asking bogus questions".
10. (occasional MIT usage) One who lives at Random Hall. See
