Here’s a simple chat app I created as an example of using (hooks flavoured) React with Firebase, all in TypeScript. It’s a little like the YouTube superchat thing, whereby everyone can log in with single click Google authentication and all chat to each other.

Optimal scrolling for 2D games or UIs
I recently stumbled upon an old bit of code which demonstrates a technique I created for an efficient scrolling data grid on the YouView TV platform. I call it ‘Blit Scrolling’. Below is a demo of the concept.

SmoothBitmap – How to ensure Bitmap pixel smoothing in AS3
A common oversight in Flash projects, when using a Bitmap with loaded content is that Flash will revert a Bitmap’s smoothing parameter to false when you replace its bitmapData. That is, when the data loads into the Bitmap, anti-aliasing will get turned off. This is 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 much better to code defensively for it.
This little SmoothBitmap class is for just such an occasion. Instantiate it like a regular Bitmap and, no matter what another developer does with it, smooth, anti aliased pixels when scaling/rotating will be ensured. Enjoy 🙂
