48 hours of Code School for free

Code School is running a promotion this weekend offering any of their classes free for 48 hours. I'm reviewing my jQuery and learning some Backbone.

jQuery has been in my toolset for years, but it's helpful to spend some time skimming through materials looking for gaps in my knowledge. Most of my experience with jQuery is in the 1.5 and earlier era, so maybe there will be some bits that are new to me.
