While testing a web application, sometimes it's useful to batch test a number of URLs. Even more, some applications might not be too friendly towards free browsing, thus when testing something like this, it might be a good idea to keep some sort of state on the client (cookies for example).

Ever wondered what kind of music you listen to? Last.fm (and Audioscrobbler underneath) allows users to track their listening habits and find some other bands/songs that they might like.

Yesterday I played a bit with Ruby, RMagick and FlickrAPI. I have to admit that I'm very impressed by the ImageMagick library and the RMagick Ruby bindings seem to work very smooth.
