Dave Knott writes: Amazon has both announced and released a new, free game engine, Lumberyard, which offers deep integration with its Amazon Web Services server infrastructure to empower online play, and also with Twitch, its video game-focused streaming service. Lumberyard is powerful and full-featured enough to develop triple-A current-gen console games, with mobile support is coming down the road. Its core engine technology is based on Crytek's CryEngine. However, Lumberyard represents a branch of that tech, and the company is replacing or upgrading many of CryEngine's systems. Monetization for Lumberyard will come strictly through the use of Amazon Web Services' cloud computing. If you use the engine for your game, you're permitted to roll your own server tech, but if you're using a third-party provider, it has to be Amazon. Integration of Amazon's Twitch video streaming tools at a low level also helps to cement that platform's dominance in the game streaming space. Alongside Lumberyard, the company has also announced and released GameLift, a new managed service for deploying, operating, and scaling server-based online games using AWS. GameLift will be available only to developers who use Lumberyard, though it's an optional add-on. The game engine is in beta, but is freely usable and downloadable today.Read Replies (0)

An anonymous reader writes: A week ago, Google suddenly removed Adblock Fast from its Android app store. Today, the ad blocker has been reinstated, enabling Samsung users to download it once again from Google Play. Late last month, the browser preinstalled on Samsung's Android phones gained support for content-blocking plugins, and the first plugin to support the functionality was a free and open-source solution called Adblock Fast. Rocketship Apps, the maker of Adblock Fast, uploaded the Android plugin on January 29, but Google rejected an app update on February 1. The app hit Google Play's top spot for free, new productivity apps on February 2, and was pulled by Google on the same day.Read Replies (0)

MojoKid writes: Intel's latest generation of processors built on the Skylake architecture are efficient as well as seriously fast. The flagship, Core i7-6700K, is an interesting chip as it's clocked at a base 4GHz, and can peak at 4.2GHz with Turbo Boost. Of course, as fast as the 6700K is, overclocking can always help take things to the next level, or at least temporarily explore future potential. In Chi-Kui Lam's case, he did just that, and managed to break a world record for Intel processors along the way. Equipped with an ASRock motherboard, G.SKILL memory, and a beefy 1.3KW Antec power supply — not to mention liquid nitrogen — Lam managed to break through the 7GHz barrier to settle in at 7025.66MHz. A CPU-Z screenshot shows us that all cores but one were disabled — something traditionally done to improve the chances of reaching such high clock speeds.Read Replies (0)

AthanasiusKircher writes: The Atlantic has an >extended article on the recent surge in advanced math education at the primary and secondary levels in the U.S., arguing that last year's victory for the U.S. in the Math Olympiad was not a random anomaly. Participation in math camps, after-school or weekend math "academies," and math competitions has surged in recent years, with many programs having long wait lists. Inessa Rifkin, co-founder of one of these math academies, argues that the problems with math education begin in the 2nd and 3rd grades: ""The youngest ones, very naturally, their minds see math differently.... It is common that they can ask simple questions and then, in the next minute, a very complicated one. But if the teacher doesn't know enough mathematics, she will answer the simple question and shut down the other, more difficult one." These alternative math programs put a greater focus on problem-solving: "Unlike most math classes, where teachers struggle to impart knowledge to students—who must passively absorb it and then regurgitate it on a test—problem-solving classes demand that the pupils execute the cognitive bench press: investigating, conjecturing, predicting, analyzing, and finally verifying their own mathematical strategy. The point is not to accurately execute algorithms, although there is, of course, a right answer... Truly thinking the problem through—creatively applying what you know about math and puzzling out possible solutions—is more important."

jones_supa writes: These days, the motivation to use open source software for many people is to avoid backdoors placed by intelligence organizations and to avoid software that has hidden privacy-intruding characteristics. For the operating system and userspace software, open choices are already available. The last remaining island has been the firmware included in various ROM chips in a computer. Libreboot has introduced an open BIOS, but it is not available for newer systems featuring the Intel ME or AMD PSP management features. Talos' Secure Workstation fills this need, providing a modern system with 8-core POWER8 CPU, 132 GB RAM, and open firmware. The product is currently in a pre-release phase where Raptor Engineering is trying to understand if it's possible to do a production run of the machine. If you are interested, it's worth visiting the official website. Adds an anonymous reader about the new system, which rings in at a steep $3100: "While the engineers found solace in the POWER8 architecture with being more open than AMD/Intel CPUs, they still are searching for a graphics card that is open enough to receive the FSF Respect Your Freedom certification." Update: 02/08 18:44 GMT by T : See also Linux hacker and IBM employee Stewart Smith's talk from the just-completed linux.conf.au on, in which he walks through "all of the firmware components and what they do, including the boot sequence from power being applied up to booting an operating system."
Update: 02/08 23:30 GMT by T :FSF Licensing & Compliance Manager Joshua Gay wrote to correct the headline originally appeared with this story, which said that the Talos workstation described was "FSF Certified"; that claim was an error I introduced. "The FSF has not certified this hardware," says Gay, "nor is it currently reviewing the hardware for FSF certification." Sorry for the confusion.Read Replies (0)
