Recently I have learned: What a covariance matrix is. That "fuggedaboutit" means "fugGEDaboutit" and not, as I had previously mystifiedly assumed, "FUGG'Daboutit". That my cs network registration actually went through for my desktop machine, even though it seems I received no email about it; I just tried nslookuping the machine this morning, and it worked. I should hook it up after lunch and do DNS-y stuff. functor.org will soon rise again from its ashes!
