CVS -- a beginner's guide
By request of my friends and colleagues. This no-brainer introduction to CVS became strangely controversial in the Fall of 1999. [Cf Henry VI Part II, Dick to Jack Cade.]
Dealing with Spammers
When I was PostMaster here I tried to deal with UCEs, spams, scams, etc. which showed up in our local mail to the annoyance of our users. The rising incidence of junk mail over time made it hard for me to respond to all of the incidents, so I wrote this DIY page for anyone who's been irritated by junk email. It is somewhat dated now but may still be educational.
Bus Schedules
