I've [read through this thread](https://ethereum.stackexchange.com/questions/191/how-can-i-securely-generate-a-random-number-in-my-smart-contract) and [this thread](https://ethereum.stackexchange.com/questions/34988/honest-lottery-winner-generation-pseudo-random-number-obtaining) and they offer a lot of interesting techniques, but what's the minimal code snippet for the currently accepted method of generating a random number in solidity?

This isn't a super high security need, approximates and PRNG solutions are fine for my use-case, so long as it spans any of the values of uint with (not lottery level, but roughly) equal probability.
