Sometimes I feel like I have a decent understanding of cryptology. And then I read an article like this and realize that I know practically nothing.

"Anyone attempting to generate random numbers by deterministic means is, of course, living in a state of sin." - John von Neumann

Simply hook up your RND to the logic circuits of a Bambleweeny sub-meson brain, give it a fresh cup of really strong tea and plug it in!
