 Hi, I'm Ruben. I just started Changer Technologies in Pune a few months ago. So feel free to talk to me about it after the session. During this session that I'm going to hold, I will talk about mostly backbone and then synchronized models using Socket I.O. What that means is using Node.js in Socket I.O. you might know. It's very easy to exchange data between different clients and the server. And I want to explain how to use backbone models to only write one model for both server and clients and then have them synchronized or updated throughout your application. This will be beneficial when you're, for example, making an application where two or more users want to work on, for example, one document or one model, whatever that might be. So I will give a nice example also during the session. That's it.
