Tomorrow morning, I'm teaching regular expressions in the OUCS public Perl course; anyone from the University can come along and be taught basic Perl. It's a six week course of three hours a week - to give you a clue about the pace of it, we spent three hours a couple of weeks ago just on arrays. We're talking absolute beginning programmers here. Still, it's good fun.
I spent the day writing the course; I'm pretty much ready, although I haven't written all the notes I need - I don't have anything on substitution, say, but I'm sufficiently prepared I can make it up on the hoof. Fun.
