http://www0.cs.ucl.ac.uk/staff/d.jones/GoodPracticeRNG.pdf

rule 1, do not use systemgenerators
rule 2, use a good rng and build it into your code
rule 3, properly seed your generator

dev_random:

Do you have a radio? Tune it in between stations. Music is highly reproducible,
and although DJ's may blabber at random they may be recorded (so reproducible)
and any radio station in general is duplicated with care in the whole area of
broadcast. Do not use the FM tuner of your radio, because FM is based on a beacon
signal with the sounds wrapped around it -- in other words, the radio can recognise
absence of a station and refuse to tune in, or adapt tuning to a nearby station.
You want to use the AM tuner, which does not have these problems.

the best random number generators use radioactive decay as an entropy source
