Wearing a burqa is not a personal choice

Whenever there is discussion about the burqa, all such discussion is immediately shut down with people putting their fingers in their ears and shouting "choice" and "religious freedom" and refusing to hear anything else.

Even in more liberal Islamic countries it's usually taken as a sign of the woman not being chaste, in other words a "slut", if not outright a prostitute. In many of these countries women wh

Chess engines

I find chess engines, and how they have advanced in just the last ten years, really fascinating. In 1997 the chess computer Deep Blue gained a lot of notoriety for being the first computer to beat a world-reigning chess master, Garry Kasparov , in a tournament of several games with long time controls. (More specifically, 6 games were played, and the score was 3½–2½ in favor of the computer.) Since then, however, chess engines have advanced in major leaps. Note that Deep Blue was a dedicated computer for the sole purpose of playing chess. It could calculate approximately 200 million nodes (ie. chess positions) per second. Modern top chess engines will run on a regular PC, and their calculation speed on such a PC, even when using eg. 4 cores, is less than 10 million nodes per second, only a small fraction of what Deep Blue was capable of. Yet these modern chess engines, running on a regular PC, are significantly stronger than Deep Blue was, and would easily beat it (and even th
