`
`Word Origin and History for ran-dom
`
`adj.
`
`"having no definite aim or purpose," 1650s, from at random (1560s), "at great speed" (thus,
`"carelessly, haphazardly"), alteration of Middle English noun randon "impetuosity, speed"
`(c.1300), from Old French randon "rush, disorder, force, impetuosity," from randir "to run fast,"
`from Frankish *rant "a running" or some other Germanic source, from Proto-Germanic *randa
`(cf. Old High German rennen "to run," Old English rinnan "to flow, to run;" see run
`(/browse/run) (v.)).
`
`In 1980s U.S. college student slang it began to acquire a sense of "inferior, undesirable." (A
`1980 William Safire column describes it as a college slang noun meaning "person who does not
`belong on our dormitory floor.") Random access in reference to computer memory is recorded
`from 1953. Related: Randomly; randomness.

`
`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."

`(http://dictionary.reference.com/browse/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
