The fear, uncertainty and doubt (FUD) is been slung around by profiteers like folding chairs at a WWE event. The haters are still being haters. Nothing new there. But now I see JavaScript companies’ desperate pleas for Flex developers to start using their HTML5 software. The context is all wrong here.  Very, very few Flex developers have shifted, moved, changed over, or whatever you want to call it… to HTML5 (or anything else JS-based.) There is not a move to HTML5 I will go as far as to say that there is not a move to HTML5. The simple fact is that, developers are being developers. No matter the background, we are always trying to broadening our skill sets. This includes HTML5 since it started showing up a few years ago. For anyone to imply, or state outright, that there is some mass exodus from Flex is completely false! The reality is still the same, Flash Player ... (more)

Back and Forth

For over a decade now, we have been trained to use the "back" and "forward" buttons in our Web browser to review or backtrack previously viewed content. We are trained to the point that there are even keyboard shortcuts. Unfortunately, this can be a problem when browsing Flex applications. Being the well-trained users that we are, we often forget that we could cause the Flex application to reload unwittingly. Fortunately, there is a solution that is built into the Flex SDK and HTML templates that are generated in a Flex Builder project. By default, Flex enables history managemen... (more)

Adobe Flash and Flex Accessibility with Screen Readers

First, yes, screen readers can read Flex applications. And yes, its fairly easy. But, I’ll discuss how in a future post. But, if you’d rather send people to your old HTML version of your site when using a read, there is good news. 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)

Security Soapbox – Decompile Flash/Flex

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: Tr... (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)
