Having built/architected/developed/consulted many Adobe Flex applications and being one of the first certified Flex instructors in the world, I’ve seen a lot of Flex applications. Some good, some bad. But no matter how many applications or who I’m talking to, I always stress the importance of securing proprietary information. By securing, I mean don’t put it in your application. Unless your are encrypting your application and decrypting at runtime, you are subject to a decompiler exposing your secrets. There are Flash decompilers that will take any SWF and give you the source: Trillix Flash Decompiler is one of the best commercial tools I’ve found. I’ve even seen guys decompile, make changes and then recompile a Flex app. This is scary! Say goodbye to licensing software in Flash. But HP just released a tool that has caught my eye as well.

Flash Player has the ability to detect if a screen reader is running on the client machine, even if JavaScript is disabled and/or the Flex application is not compiled as an “accessible swf”. This is possible with the Accessibility class. It is important to note that if the Flex application is compiled as an “accessible swf”, the screen reader will also ... (more)

FITC Mobile Presentation on iPhone Development

Just finished my presentation at FITC Mobile 2009 in Toronto. And it went very well! I had lots of questions and was able to answer all but one. The presentation was about building native iPhone applications using JavaScript and HTML instead of Objective-C. I’m currently using Titanium Mobile to does this. I’ve posted a slide share of the iPhone development presentation at On3. ... (more)

Flash Player Is Not Open = Big Fat Lie; HTML5 Is the Savior

Flash Player is open and SWF is documented The core of Flash Player is the Tamarin Virtual Machine, which is an open source project under Mozilla. While the SWF file format is not fully open, it is documented by the community on osflash.org. Additionally, there are numerous open source products that read and write SWF files. The Flash Player’s product direction has traditionally been heavily influenced by the community and their needs. The core language for Flash Player is an implementation of ECMAScript 262, which is the same specification for JavaScript. Flex also uses CSS for s... (more)
