Beautiful fractal art. Get lost in this piece; then wander into others linked below it.

I've been capturing some of the RC glider combat with an on-board HD action camera this summer. This is its first footage on a truly epic day. It requires a kind of perfect storm that happens only once or twice a year. It's a shame you can't see or feel the wind because there is so much energy. It's blowing about 20 MPH almost straight up. We pass each other frighteningly fast but these planes are built to take such abuse. View in HD at 60 FPS if you can.

Burkard Polster, otherwise known on YouTube as the Mathologer just
published two videos on solving MagicCube4D. I worked closely with him on it and think he did an incredible job. Just follow his clear instructions and you too can get yourself listed in the MagicCube4D Hall of Fame. Nothing gives you nerd bragging rights quite like that!

Wild San Francisco parrots showed up on my fire escape a few days ago. What a lovely couple. Flocks will commute over my neighborhood most days and create quite a racket but rarely stop here. They even fly in obvious couples but every once in a while there will be a lone parrot or a group of three which makes me sad. I'd like to think that they sometimes form triplets but I suspect two are always competing for the third. They sleep in a grove of ginko trees downtown and there's always a lot of drama before they settle down. I think they're a lot like us.

The most frightening image I've seen in a long time. Thanks a lot, John Oliver.

A pretty tidy result in a very exciting field.

This is how AlphaGo resigns.

Lee Sedol finally wins a game against AlphaGo in a very dramatic fashion. During the commentary the question arose as to just how AlphaGo resigns, if at all. Michael Redmond correctly guessed that it probably prints a message to the operator's screen who then resigns on its behalf. At one point the screen was visible in the background with a pop-up window in the center. I snapped a HD screen shot and straightened the oblique view of the screen back into a square and this is what I got. You can just make out the text which reads "AlphaGo resigns. The result W+resign was added to the game information." No way to know if it was accompanied by the wilting Pac Man sound.
