After all of the debate with the news that CoffeeScript will be bundled in Rails 3.1, I made a new site: http://doihavetousecoffeescriptinrails.com/.
If you’re looking for a real article on the subject, Peter Cooper has a great post on Ruby Inside summarizing Rails 3.1, CoffeeScript, jQuery, and SASS.
I have to say that for the past couple of hours i have been hooked by the amazing articles on this blog. Keep up the wonderful work.
