A Weird New Scam | stderr – Remember when FTB went down for a few days around September 12 or so? Marcus Ranum explains what happened, entertainingly. The short version is, someone claimed they had a copyright on the banner image–you know, the one that says freethoughtblogs.com on it–and the hosting service shut down the site because DMCA is fundamentally broken.
Fractal Mazes – Commenter amito pointed me to their fractal maze browser app (see app, Github). (Solver beware: I’m pretty sure the first maze by Noke Lieu just doesn’t have a solution.) And then Jay McArthur linked to their own github page with a collection of more fractal mazes with citations, plus a python app. I’m proud to have made three mazes featured in both of these. I made them a long time ago (here’s one), but they’re still kicking around.
Fractal mazes are great, I love them. I first heard about fractal mazes in 2003 through MathPuzzle, and then I designed three myself almost a decade ago. You cannot solve fractal mazes with the conventional right-hand rule, but there is a computationally efficient terminating algorithm that will solve any fractal maze. Perhaps one day I will describe the algorithm.
