"Often when I woke in the night, horrific pictures sprang unbidden to my mind—Satan, cupping his hand below Sniff's chin to drink the blood that welled from a great wound on his face; old Rodolf, usually so benign, standing upright to hurl a four-pound rock at Godi's prostrate body; Jodeo tearing a strip of skin from Dé's thigh; Figan, charging and hitting, again and again, the stricken, quivering body of Goliath, one of his childhood heroes. ..."

Nominative determinism strikes again.

I seem to have set a world record.

A few months ago, I was playing Beggar My Neighbour with Iain and, after the game had gone on long past bedtime, we wondered if it might go on forever. I thought this was an interesting question and after the game did finally end (he won), I looked into it and found that nobody knows whether there are any infinite games of Beggar My Neighbour. There are only a finite number of possible games, and computers are fast these days, so I wondered if it might be possible to check all the games and answer this open question.

Well, even with today's fast computers (and a whole lot of them - access to a whole lot of computers is one of the useful things about working at Google), it would take an unreasonably long time to play all possible games of BMN, but maybe I'd get lucky and find an infinite game (if any exist) quickly. Or maybe I'd find a new "longest known" game and set a record - which I've done.

Some photos from our holiday in Wales, including a terrifying ascent of Crib Goch, the beautiful Pembrokeshire coast and Viktoria's first trip to Wimpy

On the one hand it's great if econometricians use these tools, on the other hand all this info is already available on Wikipedia to the even slightly interested - why would people need to wait until someone writes in in their economics journal?
