Usually it's not really totally uniformly random, but still quite unpredictable :)

Appropriate sources of entropy Posted May 30, 2008 22:16 UTC (Fri) by ejr (subscriber, #51652) [Link] Search for "randomness extractor" for information on turning an unknown random distribution into a known one. It's quite difficult, but often possible. Cool combinatorics at work, and also closely related to error correcting codes and hashing. (They're all related by the concept of distance between and distinguishability of the sampled points.)
