Submission + - Folding@home killing the planet

Drakaal writes: "Folding@Home is Killing the planet

Folding@Home costs nearly $70million, uses 584gigawatt hours of power, and produces 730 kilotons of Carbon dioxide. Is fighting mad cow worth it? This article weighs the cost benefit of donating electricity and CPU Cycles, VS. the Real Cost of the project."

Submission + - Keep your avatars happy or else

coondoggie writes: "Smile and the world smiles with you? Seems so, even in cyberspace. Ohio State University research released today says the simulated emotions of digital characters on Web sites have a real impact on potential customers looking at them. The study, appearing in the International Journal of Human-Computer Studies, found that digital characters might be better merchants if they act consistently happy, even if the products they're selling — such as novels or movies — are heart-wrenchingly sad. Still...If your avatar is going down to protest Second Life headquarters, you might want to look a little mean. http://www.networkworld.com/community/?q=node/1265 2"

Submission + - Inside the kernel of a Windows Alternative

holden writes: "NewsForge is talking about a recent talk ReactOS lead kernel developer, Alex Ionescu, gave about the internals of ReactOS. In his talk, Ionescu explains the similarities between ReactOS and Windows. and how ReactOS is close to being API compatible with Windows Server 2003. The talk looks at a lot of the technical details of how the ReactOS team implements the Windows NT kernel functionality, along with some of the problems they've faced from graphics drivers which use hard-coded values and work-arounds they are considering."

Submission + - VIPeR: Israel's Killer Robot

Guy Yernisberg writes: Israeli defense contractor Elbit Systems has just completeted the final model of its new VIPeR autonomous defense robot. It's armed with an Uzi submachine gun and can throw grenades. It has an onboard camera for aiming and identifying possible targets. The problem is, once armed, it shoots at everything it can see. It's supposedly intended for use against Palestinian and Lebanese guerilla fighters — but they live amongst the civilians and not in "combat zones" as the IDF claims. Releasing a killing machine in the middle of a city might not be such a good idea after all.

Submission + - Auto-parallelizing compiler from Codeplay

Max Romantschuk writes: "Parallelization of code is a very tricky thing. We've all heard of the challeges with Cell, and with dual and quad core pocessors this is becoming an ever more important issue to deal with. The Inquirer writes about a new auto-parallelizing compiler called Sieve from Codeplay: What Sieve is is a C++ compiler that will take a section of code and parallelize it for you with a minimum hassle. All you really need to do is take the code you want to run across multiple CPUs and put beginning and end tags on the parts you want to run in parallel.

Is this the Silver Bullet of parallelization? There's more info on Sieve on Codeplay's site."

HP Disables VT On Some Intel Laptops 258

snoukka writes "I just bought a new HP nx9420 laptop in order to use it with Linux, XEN, and windows on XEN. I was very disappointed when I noticed that the processor had this feature but VT is disabled in BIOS by HP and cannot be enabled! Disabled!? It's like buying a car with turbo and finding out after buying it that this turbo 'feature' was disabled." The forum thread goes back to last August and is still live. The latest post from an HP rep indicates that new firmware for the nx9420 should be available later this week in which the ability to switch on VT is enabled. It's not clear whether other HP products, in which VT was also disabled, will also get new firmware.

Skype Unleashed Onto Cell Phones 74

An anonymous reader writes "Today Hutchinson announced that it would provide unlimited cell phone to cell phone Skype calls via a 3G connection. This new service, called X-series, is part of a new alliance made up of Skype, Sling Media, Yahoo, Nokia, Google, eBay, Microsoft, Orb and Sony Ericsson. According to the article, users will also be able to 'search Google and Yahoo, send MSN instant messages to their friends, watch their TVs from a Slingbox, access their computer at home with Orb and buy or sell stuff on eBay.' Users will only get charged a monthly fee for access, in a similar way to broadband charges."

Screenshot Accounts 'Delisted' on Flickr 210

An anonymous reader writes "Flickr and Second Life fans seem to have collided head-on over a little known policy on Flickr that 'delists' an account from public areas, including search, when more than half of your content is non-photographic in nature. Flickr stated that most people searching the site are looking for photographic content so the restriction is in place merely to keep the site focused on its original intent. From the article: 'As a result, many screenshots on Flickr are AWOL — at least as far as the general public is concerned. That's angering and confusing some of the people who carefully stage scenes in the popular virtual world and religiously post the results online.'"

A Look at FreeNAS Server 214

NewsForge (Also owned by VA) has a quick look at FreeNAS, an open source network attached storage server that can be deployed on pretty much any old PC you have sitting around the house. From the article: "The software, which is based on FreeBSD, Samba, and PHP, includes an operating system that supports various software RAID models and a Web user interface. The server supports access from Windows machines, Apple Macs, FTP, SSH, and Network File System (NFS), and it takes up less than 16MB of disk space on a hard drive or removable media."

UK Government Wants Private Encryption Keys 822

An anonymous reader writes "Businesses and individuals in Britain may soon have to give their encryption keys to the police or face imprisonment. The UK government has said it will bring in the new powers to address a rise in the use of encryption by criminals and terrorists." From the article: "Some security experts are concerned that the plan could criminalise innocent people and drive businesses out of the UK. But the Home Office, which has just launched a consultation process, says the powers contained in Part 3 are needed to combat an increased use of encryption by criminals, paedophiles, and terrorists. 'The use of encryption is... proliferating,' Liam Byrne, Home Office minister of state told Parliament last week. 'Encryption products are more widely available and are integrated as security features in standard operating systems, so the Government has concluded that it is now right to implement the provisions of Part 3 of RIPA... which is not presently in force.'"

Homeland Security Uncovers Critical Flaw in X11 517

Amy's Robot writes "An open-source security audit program funded by the U.S. Department of Homeland Security has flagged a critical vulnerability in the X Window System (X11) which is used in Unix and Linux systems. A missing parentheses in a bit of code is to blame. The error can grant a user root access, and was discovered using an automated code-scanning tool." While serious, the flaw has already been corrected.

Canadian Music Stars Fight Against DRM 506

An anonymous reader writes "Some of Canada's best known musicians, including Avril Lavigne, Sarah McLachlin, Sum 41, and Barenaked Ladies, have formed a new copyright coalition. The artists say in a press release that they oppose file sharing lawsuits, the use of DRM, and DMCA-style legislation and that they want record labels to stop claiming that they represent their views."

Internet2 Gets a New Backbone 175

wrong_fuel writes "A few of you know that Internet2 and NLR (National Lambda Rail) have been in talks for some time regarding a merger of the two networks. Those talks have fallen apart and Internet2's contracts with Qwest communications had already been allowed to lapse. Internet2 has now reached an agreement with an unnamed carrier for its next generation backbone. The new network will likely be named later this year (the old one was referred to as "Abilene") and current member Universities will be migrated off of Abilene by September 2007."
