Machine-Vision Algorithm Learns to Transform Hand-Drawn Sketches Into Photorealistic Images.

> A more promising approach is to use machine-vision algorithms that rely on neural networks to extract features from an image and use these to produce a sketch. In this area, machines have begun to rival and even outperform humans in producing accurate sketches.

> But what of the inverse problem? This starts with a sketch and aims to produce an accurate color photograph of the original face. That’s clearly a much harder task, so much so that humans rarely even try.

> Now the machines have cracked this problem. Today, Yagmur Gucluturk, Umut Guclu, and pals at Radboud University in Denmark have taught a neural network to turn hand-drawn sketches of faces into photorealistic portraits. The work is yet another demonstration of the way intelligent machines, and neural networks in particular, are beginning to outperform humans in an increasingly wide variety of tasks.

Several years ago I got to the point where I actively avoid open source projects hosted on SourceForge. The whole SF enterprise feels scuzzy and like it is stuck circa-2001.

There's a couple of things (mainly KeePass) I use that are still hosted on SF but every time I have to download them I've got this undercurrent of resentment that I'm sure these projects don't want me feeling towards them.

Just move to GitHub already!

(on the other hand I get theoretically nervous about GitHub being so dominant…in 10 years everyone will be on GitHub and it will be the new SourceForge)

Pretty heartbreaking to read about how terrible things are in Venezuela

While Venezuelans were dying for lack of simple, inexpensive pills, their radical socialist government was spending tens of millions a year to keep a native son, Pastor Maldonado, competing in the Formula 1 global auto-racing circuit.

Venezuela’s state-owned oil company, PDVSA, spent some $45 million each year to keep Maldonado racing under its logo. Why an oil company without a retail arm and with monopoly rights to Venezuelan oil needs to advertise in the first place was never clear.

This idea that whenever something evil happens someone particular can be blamed and punished for it, in life and in politics is hopeless.
