Low Quality Alloy Cause of Shuttle Main Tank Issue 118

Posted by Soulskill from the heisenberg-compensators-were-acting-up dept.
BJ_Covert_Action writes "NASA engineers have finally discovered the root cause of the cracks that have been found on space shuttle Discovery's main external tank. The main tank, one of the 'Super Lightweight Tank' models developed by Lockheed-Martin, employs an aluminum-lithium alloy developed by Lockheed-Martin specifically for this application. The new alloy is used in various structural stringers throughout the SLWT design. Unfortunately, the batch of this alloy used in the tank that is currently mated with the Discovery shuttle appears to be of low quality. The alloy used in the stringers has a 'mottled' appearance, compared to the nominal appearance typically used in the main tank stringers (see picture in article). This appearance is indicative of a fracture threshold that is significantly lower than typical. NASA has determined, through testing, that this low grade alloy has only 65% of the fracture strength of the nominal alloy typically used. NASA engineers have devised a potential fix to the problem that they are currently testing to ensure the repair will cause no unintended consequences. NASA plans to have the Discovery shuttle ready to launch again by February 24th, 2011."

AMD Demos Llano Fusion APU, Radeon 6800 Series 116

Posted by timothy from the onward-ever-onward dept.
MojoKid writes "At a press event for the impending launch of AMD's new Radeon HD 6870 and HD 6850 series graphics cards, the company took the opportunity to provide an early look at the first, fully functional samples of their upcoming 'Llano' processor, or APU (Applications Processer Unit). For those unfamiliar with Llano, it's 32nm 'Fusion' product that integrates CPU, GPU, and Northbridge functions on a single die. The chip is a low-power derivative of the company's current Phenom II architecture fused with a GPU that will target a wide range of operating environments at speeds of 3GHz or higher. Test systems showed the integrated GPU had no trouble running Alien vs. Predator at a moderate resolution with DirectX 11 features enabled. In terms of the Radeon 6800 series, board shots have been unveiled today, as well as scenes from AMD's upcoming tech demo, Mecha Warrior, showcasing the new graphics technology and advanced effects from the open source Bullet Physics library."

UK ISPs Profit From Coughing Up Customer Data 59

Posted by Soulskill from the they-call-it-monetization-of-assets dept.
nk497 writes "ISPs in the UK are charging as much as £120 to hand customer data over to rightsholders looking for proof of piracy, according to the Federation Against Software Theft. While ISPs have to hand over log details for free in criminal cases, they are free to charge in civil cases — and can set the price. 'In 2006, we ran Operation Tracker in which we identified about 130 users who were sharing copies of a security program over the web,' said John Lovelock, chief executive of FAST. 'In the end we got about 100 names out of them, but that cost us £12,000, and that was on top of the investigative costs and the legal fees.'"

New Mars Rover Rolls For the First Time 100

Posted by Soulskill from the keep-them-doggies-rollin dept.
wooferhound writes "Like proud parents savoring their baby's very first steps, mission team members gathered in a gallery above a clean room at NASA's Jet Propulsion Laboratory to watch the Mars Curiosity rover roll for the first time. Engineers and technicians wore bunny suits while guiding Curiosity through its first steps, or more precisely, its first roll on the clean room floor. The rover moved forward and backward about 1 meter (3.3 feet). Mars Science Laboratory (aka Curiosity) is scheduled to launch in fall 2011 and land on the Red Planet in August 2012. Curiosity is the largest rover ever sent to Mars. It will carry 10 instruments that will help search an intriguing region of the Red Planet for two things: environments where life might have existed, and the capacity of those environments to preserve evidence of past life."

New LLVM Debugger Subproject Already Faster Than GDB 174

Posted by timothy from the pop-will-eat-itself dept.
kthreadd writes "The LLVM project is now working on a debugger called LLDB that's already faster than GDB and could be a possible alternative in the future for C, C++, and Objective-C developers. With the ongoing success of Clang and other LLVM subprojects, are the days of GNU as the mainstream free and open development toolchain passé?" LLVM stands for Low Level Virtual Machine; Wikipedia as usual has a good explanation of the parent project.

When Rewriting an App Actually Makes Sense 289

Posted by timothy from the old-app-was-starting-to-fester dept.
vlangber writes "Joel Spolsky wrote a famous blog post back in 2000 called 'Things You Should Never Do, Part I,' where he wrote the following: '[T]he single worst strategic mistake that any software company can make: They decided to rewrite the code from scratch.' Here is a story about a software company that decided to rewrite their application from scratch, and their experiences from that process."

Wine 1.2 Release Candidate Announced 165

Posted by timothy from the vintage-2010 dept.
An anonymous reader writes "After evolving over 15 years to get to 1.0, a mere 2 years later and Wine 1.2 is just about here. There have been many many improvements and plenty of new features added. Listing just a few (doing no justice to the complete change set): many new toolbar icons; support for alpha blending in image lists; much more complete shader assembler; support for Arabic font shaping and joining, and a number of fixes for video rendering; font anti-aliasing configuration through fontconfig; and improved handling of desktop link files. Win64 support is the milestone that marks this release. Please test your favorite applications for problems and regressions and let the Wine team know so fixes can be made before the final release. Find the release candidate here."

Microsoft Kills Support For XP SP2 315

Posted by timothy from the too-soon? dept.
Trailrunner7 writes "Microsoft's announcement this week that it is preparing to end support for machines running Windows XP SP2 not only represents a challenge for the thousands of businesses still running SP2, but also is the end of an era for both Microsoft and its customers. It wasn't until 2004 that the final release of XP SP2 hit the streets, but when it did, it represented a huge step forward in security for Windows users. It wasn't necessarily the feature set that mattered as much as the fact that the protections were enabled by default and taken out of the users' hands."

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."

MPAA Asks Again For Control Of TV Analog Ports 466

Posted by Soulskill from the keep-barking-up-that-tree dept.
suraj.sun passes along this excerpt from the Consumerist: "The Motion Picture Association of American wants to rent movies to TV viewers earlier in the release window, but they don't want anyone potentially streaming that video out to other appliances. That's why last week they went back to the FCC to once again ask for the power to disable analog ports on consumer television sets. This capability is called selectable output control or SOC, and the FCC banned it back in 2003. SOC would allow 'service operators, such as cable companies, to turn off analog outputs on consumer electronics devices, only allowing digital plugs' such as HDMI. The MPAA is arguing that if they could directly turn those plugs on and off, they could offer more goods to consumers."
