Callbacks are important part of Rails. It is used everywhere from before_filter in controller to after_destroy in ActiveRecord. Callback code has undergone a lot of change in Rails3. Beside discussing the changes from Rails2, the presentation would go in detail how exactly Rails3 made callbacks faster. The talk will also discuss a few things to watch out for while declaring callbacks on ActiveRecord. We also have two lightning talks lined up: Matt Scilipoti will show us how to create new Homebrew formulas and Josh Szmajda will teach us how to use Plucky to easily query Mongo.
