<p>The default number generator is deterministic, so it&rsquo;ll
produce the same sequence of numbers each time by default.
To make it non-deterministic, give it a seed that changes.
To produce varying sequences, give it a seed that changes.

intend to be secret, use <code>crypto/rand</code> for those.</p>
