An earlier hn post about learning Ruby (http://news.ycombinator.com/item?id=4068633) got me thinking and since I haven't seen a good list of Ruby learning resources all together in one place in a while I put together a few of what I think are some of the better resources, in no particular order - most are just ruby, a few are for Rails. I'm sure I've missed a few good ones so let me know what those are.
