Mario AI - "Mario's inner emotive states cause behavior-determining drives. For example, Mario will collect coins if he is hungry. Whereas, when he is curious, he will explore his environment and autonomously gather knowledge about items he does not know about yet."
Researchers at the MIT Computer Science and Artificial Intelligence Laboratory, Microsoft Research, and Adobe Research have presented a technique for reconstructing an audio signal by analyzing minute vibrations of objects depicted in video. For example, the method can be used to extract intelligible speech from video of a bag of potato chips filmed from 15 feet away through soundproof glass. [more inside]

For twenty years, the fastest known algorithm to multiply two n-by-n matrices, due to Coppersmith and Winograd, took a leisurely O(n^2.376) steps. Last year, though, buried deep in his PhD thesis, Andy Stothers discussed an improvement to O(n^2.374) steps. And today, Virginia Vassilevska Williams of Berkeley and Stanford, released a breakthrough paper [pdf] that improves the matrix-multiplication time to a lightning-fast O(n^2.373) steps.

Stanford has announced new online courses for January 2012. Like the three courses currently running (1,2,3), these courses are free, open to the general public, and have no required textbook (previously). [more inside]
Stanford's 'Introduction to Artificial Intelligence' course will be offered free to anyone online this fall. The course will be taught by Sebastian Thrun (Stanford) and Peter Norvig (Google, Director of Research), who expect to deal with the historically large course size using tools like Google Moderator.

Russel Cox, one of the people behind Google's new programming language Go, has written a three part series on regular expressions. It's a nice mix of computer science theory, programming, and history: Regular Expression Matching Can Be Simple And Fast, Regular Expression Matching: the Virtual Machine Approach, and Regular Expression Matching in the Wild.
