Do you think the repressive Chinese government would let the media know that their country's national processor has a flaw?

The Loongson 2E & 2F processors have flaws, but it's not like the Chinese is hiding anything.

One of the flaws is this one, and there is a software workaround for it: http://bugs.gentoo.org/show_bug.cgi?id=338405

As I have seen thus far, China is working openly with the open source projects to get their changes upstream into the Linux Kernel, glibc & tools, and other applications.

I even have a port of Open Grid Scheduler (Grid Engine fork, a batch scheduler for HPC clusters) for Loongson:

Submission + - Most IPv6-certified home network gear buggy (networkworld.com)

UNH is tight-lipped about the results, but the sad fact is that most home routers and DSL/cable modems certified as IPv6-compliant by the IPv6 Forum are so full of implementation bugs that they can't be used by ISPs for IPv6 field trials. And that's not helping the Internet have a smooth, fast transition to IPv6. Though OpenWRT and DD-WRT solve the problem, ISPs point out that requiring the average consumer to upgrade their own firmware, because the manufacturer can't do IPv6 right, isn't a practical solution."

TED attendees have even been allowed to travel inside them, on a closed course. The car is a project of Google, which has been working in secret but in plain view on vehicles that can drive themselves, using artificial-intelligence software that can sense anything near the car and mimic the decisions made by a human driver."

Visually Demonstrating Chrome's Rendering Speed 140

Posted by kdawson from the want-to-see-it-again dept.
eldavojohn writes "Recent betas of Google's Chrome browser are getting seriously fast. Couple that with better hardware, on average, and it's getting down to speeds that are difficult to demonstrate in a way users can appreciate. Which is why Google felt that some Rube Goldberg-ish demonstrations with slo-mo are in order. Gone are the days of boring millisecond response time metrics."

AMD Adds OpenGL 3.0 Support To Graphics Drivers 102

Posted by timothy from the stars-are-aligning dept.
arcticstoat writes "Just a few months after The Khronos Group unveiled the Open GL 3.0 spec last year, AMD has included full support for the new API in its first WHQL driver of 2009 — Catalyst 9.1. OpenGL 3.0 requires DirectX 10-level hardware, such as AMD's Radeon HD series of GPUs. However, unlike Direct3D 10, OpenGL 3.0's features can be enabled on both Windows XP and Vista, as well as Linux and Mac OS, which could be a bonus for game developers looking for a broad base of customers. The Khronos Group claims that OpenGL 3.0 has a 'rough feature parity' with Direct3D 10, and it provides Shader Model 4.0 support, including features such as the Geometry Shader. The Khronos Group also says that the new API will interoperate with the GPGPU API OpenCL, which could allow OpenGL 3.0 to compete with the Compute Shader promised in Microsoft's DirectX 11 API."

LED Lighting As Cheap As CFLs Invented 553

Posted by Soulskill from the bright-ideas dept.
mcgrew writes "New Scientist reports that a British team has overcome the obstacles to cheap LED lighting, and that LED lamps as cheap as CFLs will be on the market in five years. Quoting: 'Gallium nitride cannot be grown on silicon like other solid-state electronic components because it shrinks at twice the rate of silicon as it cools. Crystals of GaN must be grown at 1000C, so by the time a new LED made on silicon has cooled, it has already cracked, rendering the devices unusable. One solution is to grow the LEDs on sapphire, which shrinks and cools at much the same rate as GaN. But the expense is too great to be commercially competitive. Now Colin Humphreys's team at the University of Cambridge has discovered a simple solution to the shrinkage problem. They included layers of aluminium gallium nitride in their LED design... These LEDs can be grown on silicon as so many other electronics components are. ... A 15-centimetre silicon wafer costs just $15 and can accommodate 150,000 LEDs making the cost per unit tiny.'"

Smart Robot Capable of Hunting For Its Own "Food" 191

Posted by Soulskill from the note-to-robots-i-am-not-food dept.
coondoggie writes "Ok, maybe this is getting a little too close to bringing Terminator-like robots to life. For starters, eco-friendly engine builder Cyclone Power this week inked a contract from Robotic Technologies, Inc. (RTI) to develop what it calls a beta biomass engine system that will be the heart of RTI's Energetically Autonomous Tactical Robot (EATR). The purpose of EATR is to develop and demonstrate an autonomous robotic platform able to perform long-range, long-endurance missions without the need for manual or conventional re-fueling — in other words it needs to 'eat.' According to researchers, the EATR system gets its energy by foraging, or what the firms describe as 'engaging in biologically-inspired, organism-like, energy-harvesting behavior which is the equivalent of eating. It can find, ingest, and extract energy from biomass in the environment as well as use conventional and alternative fuels (such as gasoline, heavy fuel, kerosene, diesel, propane, coal, cooking oil, and solar) when suitable.'" We can only hope they don't team up with the Multi-Robot Pursuit System project to "search for and detect a non-cooperative human."
