A co-worker and friend of mine, Francis Cheng, recently started a new blog that I wanted to share:
Francis is a former engineer on the Flash Authoring team (and before that, a lawyer). He’s been in his current position on the ActionScript documentation team for several years. He’s also one of Adobe’s representatives on the ECMAScript language committee, so he’s got a better idea than anyone else I know of the internals and future of the core ActionScript language.
So far his posts have been really great if, like me, you’re interested in knowing more about the less-used features of ActionScript and also getting an early look at new features that will probably be in future versions of ActionScript.
