Only a brief update on the Brain Drain project for now: I have managed to get the new layout for the phone app working in Android. I now have room for defining and selecting tags to go along with the measurements. What I still have to do is actually enable this functionality in full.
Anyway, to keep you entertained waiting for the next more sizeable update, here is an interesting blog I found: 0 FPS. It covers graphics programming, geometry and algorithms. Has some pretty nice articles. Enjoy!
