Nicolas Cannasse is at it again.  This time with a PBJ (Pixel Bender File) binary file reader and writer in haXe and Pixel Bender Assembler tools. What this can do is create and decompile PBJ files with haXe, the possibilities are limitless to how this is used including dynamic pbj file creation.

The latest haXe file format library contains complete support to read and write PBJ file, enabling you to write Pixel Bender assembler directly in haXe, then compile it on-the-fly into PBJ bytes, which can then be saved on disk or loaded directly in Flash.

I plan to have much more on Pixel Bender (shaders in flash) and Adobe Alchemy (compile other languages to which is a very cool technology that involves LLVM that Nicolas also has lots of great input on.

Sean Christmann has a nice post on the AS3 AVM 2 ‘Elastic Racetrack’ cycles or virtual machine tick that runs an ES4 based javascript version of actionscript which we all know and love. The post has some info on how the AVM2 cycles run and can provide benefits to understanding frame rates and how execution is divided between script and render as well as player code from user code.
