Excursions: Went to the Imperial War Museum on Saturday. Lots and lots of aeroplanes (plus various other kinds of vehicle). One of the exibits was an old (late 1940s, I think) radar guidence system for an anti-aircraft gun. How did they do that without microprocessors? If it were designed today, you can bet that it would be running NT or somesuch.
WebDAV: Had a browse through the specs (plus the delta-V versioning protocol), and it looks good. Looking forward to subversion even more now.
