I've always thought the Eurovision Song Contest was interesting, not for the boring music, but because there's always one or two countries doing something weird. And then because of the ritual of countries distributing points. It will be interesting to see how these predictions by Martin O’Leary (who describes himself as a "recovering pure mathematician") will stack up against the results. Looks like he got the winner of 2012 right!
Tom Murphy (the seventh, apparently) wrote a program that brute-forces NES games and tries to find out how to win them by increasing lexicographic orderings. I love the results starting around 7:35.
Andre Torrez hacks the PS1 variable in bash to display a unicode burger. Neat idea. Unfortunately, my Linux font doesn't have a Unicode code point for that burger :( - luckily people are working on that problem.
