My patch (#1556112) made it into the latest release of GOCR, cool.
Lately I have been working a few things. One of them is chess-related programs. I wrote a PHP program that takes a chess FEN and displays a chessboard based on it.
Right now I am working on a program, with a PHP frontend and MySQL backend, which instructs how to run through the opening properly. It will also have a section showing how often I have played this move.
I also have another program which will use a chess engine (Gnuchess, Crafty or the like) to annotate games, and then on the moves where I blunder (or miss an opportunity), it will save that move. Then it will display all the places I blunder, so that I can look at them and learn what the proper thing to do is.
