This is an article after my own heart.  Due to my modeling and cryptography work, I’ve spent a lot of time studying random number generators.  The biggest problem with RNG’s is there are two camps: the academic ones that freak out if the initial source of entropy isn’t 100% entirely random and well thought out and those that are more practical about the issue and focus more on the algorithm being correct and performing well.  You can go browse the Linux Kernel Mailing list to see this in action.
