quote: Until fairly recently, cpu's had no direct way to generate random numbers. Intel's Pentium III introduced a hardware random number generator that uses thermal noise "to generate high-quality random and nondeterministic numbers". Wikipedia says thermal noise (a.k.a. Johnson–Nyquist noise) is "the electronic noise generated by the thermal agitation of the charge carriers (usually the electrons) inside an electrical conductor at equilibrium, which happens regardless of any applied voltage." Is thermal noise simply more random than taking a sample of the system clock to generate a random number, or does it follow the laws of quantum mechanics and is truly nondeterministic.
