6:00 - 7:00: Introduction to WebSockets: All the Bi-Directional Duplexing You Can Handle

One of the most exciting new additions to the suite of technology collectively known as "HTML 5" is an official WebSocket standard. This finally allows full duplex bi-directional communication between a client and server over HTTP.

However, the technology is still new and rapidly changing. In this talk, Johnny will explain what a WebSocket is, how it works, how to implement it on browsers that don't natively support it, and how it relates to other technologies and platforms such as HTTP long polling, Comet, Flash Sockets, mobile, and JSONP. He'll also discuss the different types of server implementations, scaling strategies, and how a it can be integrated into an existing application.


7:30 - 9:00: HTML5 Game Development

Video games are fun to play, but they are much more fun to develop. Taking an idea for a game to fruition in the browser is one of the most gratifying experiences for a software developer. And it makes testing the best part of your day!

In this talk, you'll see how to implement a game using HTML5 APIs such as Canvas, Audio, and Local Storage. With the Canvas API you can implement static games, such as board games or puzzles, with relative ease. But in this talk, we'll tackle the more difficult realm of the game spectrum by looking at the implementation of a full-blown arcade game, complete with smooth animation, sprites, and yes, explosions.

We will cover a great deal of ground in this demo-fueled overview of game development, including:

  • Animation with the Canvas API
  • Scrolling backgrounds
  • Implementing sprites
  • Developing a behavior-based game framework
  • Collision detection
  • Using sounds
  • Improving performance through timelines and profiling
  • Implementing controls, such as scoreboards
  • Making toast

Implementing a game is the most fun you can have with a computer. And we'll have a lot of fun exploring how it's done. Come join us!
