Where I was yesterday

I was in San Jose for a training this last week (XSan).

To see where my google maps adventure took me, go to maps.google.com and search for '"calaveras road", milpitas, ca'. Zoom in a couple steps and switch to satellite -- note large reservoir to the northeast, and the stark dividing line between urban and empty.

Due to the closeness of the city, the satellite footage of the reservoir and surrounding valley is high-res. I can see footpaths on the reservoir dam embankment that I noted from the road.

URL-blocking for one?

Hey all -- what would be a tool one could use to block a user-specified list of URLs in a given browser? I've been searching and just come up with a) enterprise stuff, and b) commercial content-filtering packages in the $50 range.

Solutions for both IE on Windows XP and Safari/Firefox on OSX would be relevant and useful. Thanks...
