Hey Chris and all!
I was never posting much on this site, but was lurking quite a lot back in the days
I've been checking in a few times during the last years too. Now I took a new look, as I saw that pocketmatrix.com is recommended in the PowerVR Insider FAQ as a PocketPC programming resource! Seems like stuff is happening here again (though I suppose the developer part of the site was never really dead), which is nice!
After doing my Master's Thesis in computer science in a project here at Åbo Akademi University and graduating last year, I didn't want to leave for the real world outside of university, so I decided to continue as a Ph.D. student instead
Right now I'm looking into video decoding on mobile GPUs using OpenGL ES 2.0, which explains what I was doing on PowerVR's site in the first place.
I'm currently using a Nokia N900 smartphone, which I like very much. There are maybe not as many applications developed for it as for the other mobile platforms, but the browser is great.
