Watching the prime number generator (from the

running on the 11/23 is much more entertaining than doing it on the
modern workstation I'm typing this on:

Wow... About 10s on my old MacBook Pro, and I gave up on my ancient
FreeBSD box.
Incidentally, the Wikipedia page only lists Robert
Morris as author of
dc. If anyone here is able to edit Wikipedia, now would be a good time
to get Lorinda Cherry's name on there, too.
Anyone can edit Wikipedia; if you're an editor then you have your name
shown instead of your IP address (and someone ought to fix that stupid
"cat file | cmd" construct as well), but beware of the edit-nazis who seem
to think that they "own" something that is factually wrong and keep
changing it back to suit their own cultural views e.g. Kokoda Track vs.
Trail.
