Triangle.rb - Building an API with Rails by Matthew Bass

Rails is an attractive platform for building HTTP-based APIs and it's easy to get started. In this presentation, Matthew Bass will go over the basics of creating an API controller, wiring it up with routes, and protecting it with authentication. He'll also discuss transport encodings, including the binary property list format which offers a dramatic performance boost for those of us building an API for an iOS device (in one of his own projects, he got a 30% speed boost by switching to plists).
