If you want _real_ random, you have to use a non-computer source for
your randomness. The best you get on a computer is pseudo-random.
Often it's very good pseudo-random -- most of the time, good enough
for most purposes -- but it isn't true randomness of the sort that is
delivered by (for example) particle decay.
