Miško Hevery will present on Angular.js:
Angular is what HTML would have been, if it was designed for web-apps. Web-apps are afterthought in HTML and it shows. What angular brings to the table is: Opinionated structure on how a CRUD application should be built. Impressive Data Binding story, where the model is the single source of the truth. Embrace HTML and turns it into declarative DSL which gives the developer the ability to make up one's own HTML tags/attributes Amazing testability story, both on unit-tests and end-to-end tests Ambert Ho will prsent on building realtime, single page apps using Backbone.js and Node.js
