Something personal for once. I was finally able to do my first real flight with a paraglider. The full flight took about 10 minutes and 600 meters in altitude difference. So exciting. :)

The result of my terrain hacking this weekend. The water looks quite cool by now. :) Can't say the same about the surface of the island. Plus I'm running into all kinds of precision issues.

I got a bit distracted from my WebGL stuff this weekend after stumbling across this simple technique to detect manipulations in compressed images. I decided to whiz up a quick JavaScript version of it. It actually works. In some cases. ;)

This is the current status of my WebGL terrain work. Next up: morphing away the cracks, and fixing the camera distance calculation. Wonder what it will turn out in the end! :)

The data: http://www.cc.gatech.edu/projects/large_models/ps.html ... maybe one day I'll get my hands on the wonderful highres swisstopo data...

Incredible footage from the ISS. It always makes me a bit proud to see what we have achieved as a species. :)

Awesome free book on computer vision by Richard Szeliski (one of the guys behind microsofts photosynth). Wanted to learn more about that anyway. :)

NaN in Javascript acts like a zombie, always looking for new victims to infect.
fuckNaN() stops the madness by creating traps for NaN values using getters/setters.

Got myself a new thinkpad. It was working with linux out of the box. But it took a few tweaks to get better battery performance and to get the fan to shut the fuck up.
