Artificial intelligence, algorithmic pricing, and collusion | VOX, CEPR Policy Portal
Antitrust agencies are concerned that the autonomous pricing algorithms increasingly used by online vendors may learn to collude. This column uses experiments with pricing algorithms powered by AI in a controlled environment to demonstrate that even relatively simple algorithms systematically learn to play sophisticated collusive strategies. Most worrying is that they learn to

Look ma, no locks | CompuTruthing
We describe a systematic approach for replacing locks with tasks. In this approach thread blocking is replaced by properly scheduling of tasks.

Donald Knuth's Annual Christmas Lecture | Stanford Center for Professional Development
A Conjecture That Had To Be True A few months ago, the speaker did some extensive calculations relating to a curious problem in combinatorial geometry; and the resulting numbers satisfied an amazing formula. Although this formula was known to be true only in the five or six smallest cases of the problem, it was impossible to imagine a decent world in which the formula would not hold universally. Come to the lecture and learn about the interesting sequel.

Don’t invert that matrix
There is hardly ever a good reason to invert a matrix. What do you do if you need to solve Ax = b where A is an n x n matrix? Isn't the solution A-1 b? Yes,
