Anyways, haven't been too active lately. Been working with a friend on a secret project that I can't say much about. It's been a great learning experience for both of us though.
We've been sharing what we learned and all. I finally can say that I've finally found a use for linear algebra with vector transformations. I've implementing this in my WiiControll app for easy modification of joystick values, since a single matrix can be used to scale, transpose, rotate and/or flip a vector in addition may other operations.
Also, I've learned about the XML language for files. It's an awesome tree structured markup language comparable to HTML, though it is used everywhere! I'll also be implementing this into WiiControll for better forward compatibility.
