Real Time, Real Fast

As web applications continue to become more interactive and sophisticated, real-time messaging and updates are becoming increasingly prevalent. One of the hottest new APIs in HTML5 is WebSocket, which enables true duplex communication without the overhead, complexity, and extraneous latency of HTTP-based solutions. See how the WebSocket removes these barriers to create optimal real-time delivery of messages from servers to browsers, including mobile. Although WebSocket is an exciting new API, we can easily fallback to HTTP-based techniques when WebSocket is not available with Dojo?s Socket API. The server-side is equally important, and real-ti me messaging has pushed the need for asynchronous I/O in the server. The Tunguska library is one example of create scalable real-time applications using the Node.js platform that is so perfectly suited for Comet.

This presentation will also cover the use of streaming abstractions to minimize buffering, and will consider the performance implications of topic-based publish-subscribe distribution versus filtering techniques.

Dojo 2.0: Modular, Mobile, and Reinventing Web App Development

The Dojo Toolkit is one of the original Ajax toolkits, and has reinvented itself again through a series of improvements in modularity, performance, API improvements, adjustments for HTML5 and mobile platforms, and much more to provide a stellar platform for building web apps.

Learn how Dojo's adoption of CommonJS AMD makes it a perfect toolkit for including source code from other microtoolkits, to create the most extremely optimized JavaScript toolkit for your application, big or tiny. Learn about the wide variety of new features and approaches that are available now in Dojo, as well as the forthcoming Dojo 2.0 release.

Never Bet Against the Open Web

The open web is quickly either replacing, diminishing, or lowing the barrier to entry for all native platform capabilities. Strategies for logically separating data and user experience concerns create web app architectures that are easy to modify to work anywhere.

We'll talk through engaging examples, and as an audience, make our predictions for when the web will be viable in emerging areas.
