Using events to improve testability and reduce temporal coupling.

Temporal coupling in code is usually not very obvious but can cause maintainability nightmares. Code is coupled not by direct dependencies but by depending on the state that left behind by another piece of code. Temporal coupling is not something that should be avoided but it should be expressed explicitly. Someone editing your code should be able to see clearly where dependencies lie.

Windows XP Embedded, windows as lego.

I haven't been programming much lately, I've been playing with Windows XP embedded instead. It's a great product that's not very well know. I'll probably be posting a lot more about this version of windows in the future so I thought I might start with describing my first impressions of it.
