Finally, after setting the skeleton of the game on day 1 and day 2, I’ve managed to get a chess board where you can actually play. Of course, it’s quite rudimentary and you’ll have to input the coordinates by typing them, but I think that for the moment it’ll do.

Yesterday I’ve started a blog post series where about writing a small chess interface in C. I’ve set up the types Color, PieceType, Piece, Square and Board, and talked about the general idea of the game. Finally, I’ve shown some of the logic behind printing and initializing the Board.

I’ve been programming in Haskell as my main language for almost a year now. Among other things, I love the concept of purity and expressiveness it provides. In fact, I’ve gotten so used to the functional paradigm that I’m having problems when writing code in other languages, as C, which kind of sucks because I’m a teaching assistant of a subject where we use that language.

I’ve just made an advisory about CVE-2013-1436. It was quite interesting to discover and exploit. A patch with a fix is already available. If you use xmonad along with xmobar or dzen, you should patch and re-compile your xmonad binary as soon as posible, or you’ll be exposed to a remote command injection vulnerability.

Unlike few years ago, current nouevau drivers work like a charm. The only major feature I was missing was the ability to control the fans because by default they’re very noisy, and for me silence is a feature. Fortunately, as Christmas gift one of the last commits of 2012 introduced this functionality.
