David Coletta from the Buzzword group at Adobe Systems will be talking about how to build applications that run in both the Flex and AIR runtime environments, using substantially the same codebase.

**

What happens when you take a large, complex codebase like Buzzword that was originally targeted for web browsers, and adapt it so it can also run as an AIR application? In this talk, David will address the technical and architectural challenges of adapting a codebase so that SWF binaries can be shared between the browser version and the AIR version. First, UI considerations: for example, the browser environment favors everything happening inside a single window, while AIR supports multiple document windows. Then, technical and architectural issues: for example, the Singleton pattern works better in a browser environment where every window is its own instance of the Flash Player, but not so well in a multi-window AIR environment. He will cover techniques for abstracting areas of the code that must call AIR-only APIs. And he'll also talk about packaging code into modules that load over HTTP in the browser version and load from the file system under AIR.
