I actually had a slow day, and had a chance to start reading Philip Greenspun's Travels with Samantha, an engaging account of a trip around North America.

He also administers photo.net, a database-driven photographic resource, which includes suggestions for good places to buy equipment, as well as classifieds.

And he also has an intriguing essay on "why MIT should be tuition-free" for undergraduates. If you've ever suspected that your alma mater existed primarily to siphon money from your pocket, you should read this.
