Adobe efforts in the Open Source world are not new at all, but now they have better : a new open source website to keep you up to date on Adobe open source activities. Adobe projects already in the open source website include mainly :

BlazeDS : server-based Java remoting and web messaging technology that enables developers to easily connect to back-end distributed data and push data in real-time to Adobe® Flex™ and Adobe AIR™ applications for more responsive rich Internet application (RIA) experiences.

Flex 3 SDK : Adobe® Flex™ 3 is a cross platform, open source framework for creating rich Internet applications that run identically in all major browsers and operating systems. The Adobe® Flex™ SDK is the foundation of Flex, providing the core Flex compilers, component library and debugger. Using only the free SDK and an IDE of your choice, you can build and deploy rich Flex applications.

Adobe Media Gallery : The Adobe Media Gallery (AMG) is a Flash web photo and video gallery whose appearance and behavior can be customized via XML files.

Tamarin : The Tamarin project, which is based on code contributed from Adobe, is designed to implement the upcoming version of the ECMAScript 4th Edition language specification. Tamarin will be used by Mozilla within the next generation of SpiderMonkey, the core JavaScript engine embedded in Firefox®, Mozilla's free Web browser, as well as within the ActionScript™ Virtual Machine within Adobe® Flash® Player.

Webkit : The WebKit library is used to render HTML and execute JavaScript in Adobe® AIR™. Adobe AIR allows web developers to deploy rich Internet applications on the desktop.

An interesting open source experience from Adobe to show the power of Adobe products. The new website is available at opensource.adobe.com. products released under different open source licenses including the Mozilla Public License (MPL) and the LGPL v3
