I was just browsing around for some material on ruby and I found this page very helpful:

http://www.ruby-lang.org/en/documentation/ruby-from-other-languages/

It’s not a ruby bible or anything, but I think it is a good intro for experienced programmers.

If you install XCode for OS X 10.5, it automatically comes with a version of rails. This is (generally) not the latest version however, and you must take a few steps to update it. First you need to update rubygems with the following:

macintosh$ sudo gem install rubygems-update

macintosh$ sudo update_rubygems

After updating rubygems, you should be able to update the rest of your gems without a problem (including rails) via the following:

macintosh$ sudo gem update

After that you should be ready to build a rails app.
