Submission + - Open source NAS Clustering

dago writes: I've been searching for a solution to make a "network raid" out of different NAS and storage servers, each with 2-4 HDD. In particular, I'm looking at a way to aggregate that space in a RAID5 way, to have a large, redundant space for backup and archiving. Access would be via SMB/CIFS or FTP and performance doesn't really matter.

I've already tried solutions like Lustre or GlusterFS, but they doesn't seem to provide directly "RAID5 over TCP/IP", just stripping, mirroring or both (RAID 0, 1, 1+0). On the commercial side, "scale out NAS" products usually requires to buy new, specific hardware and aims at very large installations.

Did anybody already aggregated NAS storage using open source components ? How ?

Submission + - Sony's PS3 Slim uses an updated Cell chip (goodgearguide.com.au)

angry tapir writes: "The PlayStation 3 Slim gaming console from Sony Computer Entertainment is not only smaller and cheaper, but adds hardware enhancements that make it speedier, including a new Cell microprocessor. The new chip has been manufactured using an advanced 45-nanometer manufacturing process. Based on IBM's Power architecture, the chip delivers many performance improvements while drawing less power than earlier chips. The earlier console carried a Cell processor manufactured using the 65-nm process."

Submission + - Amazon, MS, Google clouds flop in stress tests (itnews.com.au)

Eponymous writes: A seven month study by academics at the University of New South Wales has found that the response times of cloud compute services of Amazon, Google and Microsoft can vary by a factor of twenty depending on the time of day services are accessed. One of the lead researchers behind the stress tests reports that Amazon's EC2, Google's AppLogic and Microsoft's Azure cloud services have limitations in terms of data processing windows, response times and a lack of monitoring and reporting tools.

Submission + - Kevin Mitnik Gets Dumped By HostedHere.Net & A (theregister.co.uk) 2

HomerMT writes: "Famed jailed and freed hacker Kevin Mitnick has recently run into troubles with major service providers and naturally there are conflicting versions of the troubles. "Over the past month, both HostedHere.net, his longtime webhost, and AT&T, his cellular provider since he was released from prison more than nine years ago, have told him they no longer want him as a customer. The reason: his status as a celebrity hacker makes his accounts too hard to defend against the legions of script kiddies who regularly attack them." But, Mr. Mitnick feels (in a fairly convincing argument) that the lack of real security on AT&T's part is not his fault and he shouldn't be punished for it. He had a stream of Twitter posts yesterday regarding his side of the story."

Finnish Guy Gets Prosthetic USB Finger Storage 113

An anonymous reader writes "Jerry had a motorcycle accident last May and lost a finger. When the doctor working on the artificial finger heard he is a hacker, the immediate suggestion was to embed a USB 'finger drive' to the design. Now he carries a Billix Linux distribution as part of his hand."

Anti-Matter Created By Laser At Livermore 465

zootropole alerts us to a press release issued today by Lawrence Livermore National Laboratory, announcing the production of 'billions of particles of anti-matter.' "Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as positrons, shoots out of the target in a cone-shaped plasma 'jet.' This new ability to create a large number of positrons in a small laboratory opens the door to several fresh avenues of anti-matter research, including an understanding of the physics underlying various astrophysical phenomena such as black holes and gamma ray bursts." The press release doesn't characterize the laser used in this experiment, but it may have been this one.

How HP Could Turn a Novelty Into a Revolution 353

RobotsDinner writes "HP's TouchSmart desktop is cool, but a blogger suggests it could be the beginning of a revolution if HP were to finally make the move of ditching Windows and building a Linux distro around the TouchSmart UI. 'Hello, HP. The UI of your latest TouchSmart computer says something about you. You may not have recognized your own weaving-in of meaning, but it comes across quite clearly if one reads just right: You want out. You want to escape the world of Windows to which Microsoft has sequestered you for the better part of two decades. Ah, but you can. No longer does Bill Gates stand guard outside your cell ... It's time to ditch Windows and build a Linux distro around the TouchSmart UI ... Your captivity of innovation under Microsoft is over. You're free. Free to invent, as you might put it.'"

Restaurant Owners Use Zapper To Cook the Books 454

Hugh Pickens passes along a NYTimes report on software programs called "zappers," which allow even technologically illiterate restaurant and store owners to siphon cash from computer cash registers to cheat tax officials. In the old days, restaurant owners who wanted to cheat kept two sets of books. But because cash registers make automated records, hiding the theft requires getting into the machine's memory and changing that record. "...the Canadian province of Quebec may be the world leader in prosecuting zapper cases. Since 1997, zappers have figured in more than 230 investigations, according to the tax collecting body Revenu Québec... In making 713 searches of merchants, Revenu Québec found 31 zapper programs that worked on 13 cash register systems. Only two known zapper cases have been prosecuted in the United States... The cash register security industry is focused on protecting patrons and owners from theft by employees, which may be one reason so few zappers are uncovered in the United States. No one hires security experts to protect the government from devious businesses... As hard as zapper software is to detect, it is easy to make, said Jeff Moss, organizer of the annual hacker convention Def Con. 'If it runs on a Windows system and you are a competent Windows administrator, you can do it,' he said."

Vegas Star Trek Experience Closing Down 234

Leebert writes "Star Trek: The Experience at the Las Vegas Hilton is closing its doors today after the attraction owner and the hotel could not work out a renewed lease deal. In its 10-year tenure, more than 3 million people have visited the Trek themed exhibit. 'Trekkies are incensed. They've scrawled reminiscences about the exhibit on the walls inside, and they're calling Cedar Fair and the hotel to complain. But their online rumor that the space the exhibit occupies will become a theater for pop star Michael Jackson is unfounded, Sternberg said. He said nothing's decided.'"

Google Chrome, the Google Browser 807

Philipp Lenssen writes "Google announced their very own browser project called Google Chrome — an announcement in the form of a comic book drawn by Scott McCloud, no less. Google says Google Chrome will be open source, include a new JavaScript virtual machine, include the Google Gears add-on by default, and put the tabs above the address bar (not below), among other things. I've also uploaded Google's comic book with all the details (details given from Google's perspective, anyway... let's see how this holds up). While Google provided the URL www.google.com/chrome there's nothing up there yet."
