[Gllug] Thoughts on secondhand server guide price

> /dev/urandom is a bit faster than /dev/random (usually)

And a little bit less secure :-)

"A counterpart to /dev/random is /dev/urandom ("unlocked" random source)
which reuses the internal pool to produce more pseudo-random bits. This
means that the call will not block, but the output may contain less
entropy than the corresponding read from /dev/random. The intent is to
serve as a cryptographically secure pseudorandom number generator. This
may be used for less secure applications."
