> To me the beautiful thing about trying to get randomness is that as long as you have one random source then you have randomness. I.e. non-random XOR random => random. Only if the sources choose their numbers independently of each other. If the non-random is a function of the random source (e.g. the identity), then the result isn't random, it's a constant 0.
