Hi -- this is a nice tutorial!

I did want to mention that I think your verbiage is a little off here:


Note: the environment in which these programs are executed is deterministic, so rand.Intn will always return the same number.


Don't you mean that it will always return the same sequence of numbers?

[but I see your approach in keeping it very simple. Perhaps you mean in this context that if you rerun the example you will always get the same number. ]

I mean that for each sequence of calls to Intn you will get the same sequence of return values.

Technically rand.Intn will always return the same sequence of
numbers, however in this context, re-running the example will
always produce the same value.

Fixes golang/go#12370
