The Melbourne Ruby Group recently ran a Ruby Nuby night where they got a bunch of different people to do five minute presentations on various aspects of Ruby and Rails. I went along and recorded all of the presentations as screencasts. You can see them all on the Cogent Consulting screencasts page.
