Railscasts: Free Ruby on Rails Screencasts
Railscasts is a new project by Ryan Bates providing regular, free screencasts on topics relating to Ruby on Rails. As opposed to Geoffrey Grosenbach's wonderfully detailed Peepcode screencasts, Railscasts videos are very short and each is focused on a very small area. Current topics include layouts, with_scope, Symbol#to_proc, caching with instance variables, and dynamic find_by methods.
The screencasts are well produced and to the point, and feature the creepiest opening sequence of any Ruby-related screencast so far.
Note: Make sure to use the "Download" links on the Railscasts site rather than clicking on the video titles as that will result in an error.
