Whatever bug is going around at the moment, I've got it again, so blogging will be light for a few days. Felt lousy Thursday morning, surfaced briefly to do a bit of blogging, then crawled back into bed and have stayed there for most of the time, gulping pseudoephedrine, paracetamol, and codeine.
I made the mistake of attempting to do some Perl scripting... but I'm sure I can undo the damage when I feel a bit better. (Note to self : Perl is bad enough when you're feeling well... never attempt it when under the influence of anti-flu medication.)
So here's a URL, which can be filed under 'Brains' or 'Space'. It also describes the way I feel at the moment.
