Main Talk

Bindings, the Best Code is the Code Not Written, Taun Chapman

Cocoa Bindings enables you to establish a live connection between an item of data and its presentation in a view. Any change made to the data’s value, either in the view or in the object that stores the data, automatically propagates across the connection. Using Cocoa bindings reduces the glue code you once had to write to connect a view to its underlying model.

In this talk Taun Chapman will review the components that make up Cocoa Bindings and how he’s used them to great effect in his recent efforts.

An Introduction to Web Sockets, Nathaniel Symer

WebSockets is an advanced technology that makes it possible to open an interactive communication session between a client and server. With this API, you can send messages to a server and receive event-driven responses without having to poll the server for a reply. In this introduction talk Nathaniel Symer will review how the protocol works, what it could be used for, and how to use it safely; including implementing a client in Objective-C.
