Some folks migrating 3.x projects to 4.x have run into noticeable performance degradation, especially if they are using the default skins that ship with each SDK. This article attempts to explain why and propose alternative implementations.

The Halo skins are written as highly optimized ActionScript and are based on a lightweight Flex class called ProgrammaticSkin.
Flash Builder Plug-in for SAP NetWeaver Gateway going away in April A little over a year ago the Flash Builder 4.5 plug-in for SAP NetWeaver Gateway was published as a beta on Adobe Labs (at http://labs.adobe.com/technologies/flashbuilder_sap ). As a research beta, the plug-in only works with older versions of Flash Builder (4.5 and 4.6). The plug-in was never shipped as an official product, and isn’t going to be developed further – we’ve discussed open-sourcing the project with the code owners but this is unfortunately not going to be possible.

As always, you can follow my sad little Twitter account ( @pdehaan ) to see the latest aggregated posts from my mini example blog empire (as well as other random tweets).

Last week, Adobe announced the public betas of Flex “Hero” and Flash Builder “Burrito.” You can use these tools to begin creating your own mobile applications that run Flash, AIR, and Flex content, and I recommend you check them out here and here . If you’re looking for the next step in getting started with a real-world Flex app, however, you may be interested in the following: I created an open-source application called SurveyApe , which should help you get started in the process of creating robust, real-world Flex mobile applications.
