I have been moving some projects over to Rails 3 and gathering some good resources on coming up to speed on Rails 3. I thought would share 6 Great Ruby on Rails 3 Learning Resources, I hope you find them useful.
I maintain Instant Rails and looking to get it up-to-date with new Rails 3 and Ruby 1.9.2 and I would like your feedback to to what would be useful to see in a new version of Instant Rails. Please read Moving Instant Rails Forward and give me some feedback.
I ran into this problem when setting up a new MacBook Pro running Snow Leopard recently and thought others might find it useful when running into the uninitialized constant MysqlCompat::MysqlRes error when trying to connect to a MySQL from Ruby.
