Mildly interesting - but determining if a sequence of maybe random numbers actually is random is hard.<p>I'd like to see people talking about the DieHard tests, and potential problems with it. Or about the needs for different types of randomness for different applications - modelling requires large quantities of random numbers but needs to be able to recreate the same sequence later. That would be very bad for cryptography. Games need unpredictability, but true randomness isn't great. Music shuffle systems are often made less random to prevent jarring changes.
