@lupyuen that's a legit post! He talks up Linux /dev/urandom and that's pretty solid these days, but not too long ago there were a bunch of security key problems because the Linux random pool wasn't living up to its promises, and was giving back predictable "random" bits. May still be a problem on some low end SoCs!

@lupyuen I implement all my RNGs as sequential counters. Technically speaking the output is valid and random if you just accept it is statistically unlikely , but not impossible, to be produced randomly.
The only stipulation is you can only run it once :)
