If you want to write a unit test which verifies that something implements a particular interface, or extends a particular class, here’s how…
One of the most problematic constraints when developing applications for mobile or Set Top Box is video memory (AKA VRAM). You often will not have control over how much video memory is allocated to your application, or what the fallback behaviour is when your application uses too much.

Remember kids: You don’t have to please ALL your customers, just the ones you want to keep.
The first Law: conservation of users
Users are not created or destroyed, only converted to or from using a competitor’s product. Continue reading O’Donnell’s 3 Laws of User Dynamics
Improving the usability of an interface, by making it do more or less what the user actually expects of it, is a pretty good route to an overall sound user experience. Yet, there’s one key mistake almost every interface I’ve looked at makes in this regard – what I call the Spurious Stimulus Response. That is… Continue reading Wait for it…
I just tried packaging a game, written in AS3, for my iPad, PlayBook and BlackBerry 10 Dev Alpha device – works pretty well!
Unlike the iPad, the BlackBerry PlayBook has rather poor international keyboard support, with no method for entering chinese characters. I like the way iOS achieves this, so went about building my own version in ActionScript. Continue reading Chinese Handwriting Recognition App
A common oversight when using Bitmaps with loaded content is that Flash will revert a Bitmap’s smoothing parameter to false when you replace its bitmapData. It’s simple enough to fix, but since you may not know if someone is going to replace the bitmapData of a Bitmap you have created – then it’s often better to code defensively around it.
This little SmoothBitmap class is for just such an occassion. Instantiate it like a regular Bitmap and, no matter what another developer does with it, smooth pixels when scaling/rotating will be ensured.
It gets scary out there sometimes. During my freelance career I’ve worked at a lot of different companies and have seen such coding horrors as you cannot imagine. So I thought I’d start immortalising some of them – so that we can all learn better coding practices, by looking at the bad.
Starter for 10 – What’s wrong with this picture?
public function doSomething(stuff:String):void
var newPixels:BitmapData = new BitmapData(someUint, someUint, true, 0);
someBitmap.bitmapData = newPixels;
Did you spot the fubar? It’s not an obvious one. Continue reading CODING WRONGS – Where do I start with the bad?
