I spent the afternoon playing around with Google Gears in order to get a basic feel for how it works. Specifically, I wanted to see how much work it would take to add support for offline viewing for tostring.org (an online book site).

I used the Gears LocalServer API which “allows a web application to cache and serve its HTTP resources locally, without a network connection”. The implementation can be though of as a small web server that intercepts requests for remote resources and serves them (seamlessly) from a local cache. This has a couple of advantages:

I have been playing around with the jQuery Autocomplete plugin to get it working with the ActionScript 3 documentation API that I posted about earlier today.

The Autocomplete API is really nice, and pretty flexible, but one issue I ran into is that the query argument containing the user input that is passed to the server is hard coded to “q”. For my api, I needed this argument to be “api”.

I have just uploaded a new ActionScript 3 reference / online documentation API to Google App Engine. Basically, the service takes an ActionScript 3 class name (or a fragment of a class name) and returns the URL for the online documentation for the specified class.

If you have done Flash development using the Flash Authoring tool, or have done any low level work with the SWF format, then you should be familiar with the concept of symbols. Basically a symbol is a reusable object (graphics, buttons, MovieClip) that can be included in the SWF once, but referenced and used many times.

Flex 4 FXG has a similar concept of symbol, although the actual underlying implimentation is different. Using the Library and Definition elements, you can define a graphic symbol, which can then be reused multiple times within the FXG or MXML document.

As I mentioned the other day, the Flex team has released a ton of information on Flex 4. One of the new features which I am most excited about is the FXG graphic format being developed.

About a month ago, the Flex team announced that nightly builds of the next version of Flex (code named Gumbo) were now available on the opensource Flex site. Along with early versions of the SDK, the team also posted a ton of other information, including specs and API docs.

Below is a listing of links and resources about Gumbo / Flex 4. Going through these will quickly get your up to speed on what is being worked on in Flex 4, and get your ready for playing around with the new builds.
