HipHop Virtual Machine, or HHVM, reduces the median page-saving time for editors from about 7.5 seconds to 2.5 seconds, and the mean page-saving time from about 6 to 3 seconds. Below, I’ll explain the technical background for HHVM on MediaWiki and some of the far-reaching benefits of this change that will go beyond the recent performance gains. » Ori Livneh | blog.wikimedia.org
Two-player limit Texas hold’em poker has finally been solved, according to a study published in Science today. Scientists have designed a computer program, named Cepheus, with a strategy for the game that is so close to perfect that statistical analysis shows it can’t be defeated by a human poker player, even if that player competed against the computer for an entire lifetime. This means that no matter how the game starts out, the computer will win or break even in the long run — making it essentially unbeatable. » Cepheus ...
The background is set, you know why I took interest now it’s time to tell what solidified the decision. Each change made to the OpenBSD codebase undergoes a code review before it’s committed to the tree. If you managed to get that far in this article you perfectly know why I deem that of upmost importance. No matter how many features your software has, if your documentation is sub-par then your software is most likely useless. The quality of OpenBSD documentation is on a level I didn’t expect even after reading about it in so many places. Not only will you get information on how something works, what’s possible and how to use it. It will also tell you the best practices for using the tool and warn you about the common pitfalls. ...
Reading the documents, I have the feeling that the NSA can 1) decrypt weak crypto and 2) steal keys. Let’s focus on the crypto first. SSH supports different key exchange algorithms, ciphers and message authentication codes. The server and the client choose a set of algorithms supported by both, then proceed with the key exchange. Some of the supported algorithms are not so great and should be disabled completely. If you leave them enabled but prefer secure algorithms, then a man in the middle might downgrade you to bad ones. This hurts interoperability but everyone uses OpenSSH anyway. ...

A summary of some problems I faced when tinkering with Quake to get it play nicely on an oscilloscope. After seeing some cool clips like this mushroom thing and of course Youscope, playing Quake on a scope seemed like a great idea. It ticks all the marks that make me happy: low-poly, realtime rendered and open source. » Pekka Väänänen | lofibucket.com
Este jueves, 1 de enero, entra en vigor gran parte de la ley Lassalle de propiedad intelectual y con ella su artículo 32.2, que obliga a los editores y autores a cobrar —aunque no quieran— cuando los agregadores de Internet enlacen y distribuyan sus contenidos. Estos son los aspectos clave a tener en cuenta sobre el denominado canon AEDE. » M.M. | 20minutos.es
The Futurama writers had a rule that the show’s more obscure jokes couldn’t be central to the plot. So the background is stuffed with nods to mathematics, science, history, and literature. Numbers are often translated into math problems (instead of Studio 54, the crew visits Studio 1²2¹3³). Robot information is conveyed in binary (”The Honking” references the ”Redrum” scene in The Shining, when Bender is perplexed to see ”0101100101” written in blood on a wall, but then realizes that it reads ”1010011010” in the mirror, a series of digits that translates to ”666”). And of course, there’s the Alienese language. But the writers also built entire episodes around the Banach-Tarski paradox and the premise of three-dimensional characters entering two-dimensional space. ...
In May of this year, LinuxGizmos and Linux.com collaborated on a joint survey, asking our readers to choose their favorite open-spec hacker SBCs from a list of 32 that run Linux and/or Android. Our SBC survey winners, ranked one to five, included the Raspberry Pi, BeagleBone Black, Odroid-XU, CubieTruck, and Banana Pi single board computers. Thanks to the flood of new open-spec, community-backed boards, as well as the demise of others, we have updated our list for this end-of-year snapshot. ...
