Submission + - Large Hadron Collider gears up for Huge Data Flows 1

Hugh Pickens writes: "Live Science has an interesting story on the flood of information that will pour from the Large Hadron Collider (LHC), the world's next-generation particle accelerator, an underground ring 27 kilometers around located at the European Centre for Nuclear Research (CERN) in Geneva, Switzerland, starting in mid-2008. Detectors stationed around the LHC ring will produce 15 trillion gigabytes of data every year, data that will be farmed out to computing centers worldwide. In the LHC computing model, data from the experiments will flow through tiers. The Tier 0 center at CERN takes the data directly from the experiments, stores a copy and sends it to Tier 1 sites. The Compact Muon Solenoid (CMS) experiment has seven Tier 1 sites in seven nations, and each site partitions its portion of the data based on the types of particles detected and sends these sub-samples off to one of the 30 CMS Tier 2 sites where researchers and students finally get their hands on the data. "We are really good at moving data from Fermilab to our Tier 2 center," says physicist Ken Bloom at the University of Nebaska where scientists have achieved the fastest rates for any Tier 1-to-Tier 2 connection worldwide. "We can manage a terabyte an hour easily, and a terabyte in half an hour is possible.""

Submission + - Intel Answers Phenom with Unsupported CPU (pcper.com)

Vigile writes: "Sure the AMD Phenom is getting a lot of attention today but Intel wasn't going to let AMD's parade run without raining on it. In a response that seems more than a little strange, Intel brought in the release of performance data on the Core 2 Extreme QX9770 processor which runs at 3.20 GHz on a 1600 MHz front-side bus. What makes this release odd is that AMD's parts don't even come close to competing with the existing Intel high-end CPUs and that there is no chipset from Intel or elsewhere that actually supports a 1600 MHz FSB! Using current motherboards that were overclocked to run the QX9770, the performance of the new processor is simply the fastest desktop processor we have seen."

Submission + - Nano propellers for drug deliveries

Roland Piquepaille writes: "Researchers at the University of Illinois at Chicago (UIC) have used molecular dynamics simulations to build a nanoscale propeller with molecule-sized blades. This is the first time that researchers are looking at nanodevices able to pump fluids. However, they recognize that such devices will not be available before several years. If these nano propellers ever come on the market, they would be used for applications such as precisely targeting medicines and regulating flow into and out of cells. Read more for additional details and a picture of such a nano propeller."

Submission + - Google cookies expire after two years (bbc.co.uk)

An anonymous reader writes: The BBC is reporting that Google says that its cookies will now expire after two years, rather than in 2038 — if the user does not visit the website first. 'Peter Fleischer, Google's global privacy counsel, said in a statement: "After listening to feedback from our users and from privacy advocates, we've concluded that it would be a good thing for privacy to significantly shorten the lifetime of our cookies."'

Submission + - Torvalds Says GPLv3 Backers Full Of "Hot Air&# (informationweek.com)

AlexGr writes: "Last week Paul McDougall wrote in InformationWeek that Linux creator Linus Torvalds called advocates of the Free Software Foundation's GPLv3 license "hypocrites." A few readers complained he had not provided a complete picture of Torvald's feelings. They were right. Linus also thinks FSF leaders are "controlling," "condescending," and full of "hot air." And he's got more choice words for GPLv3 itself. http://www.informationweek.com/blog/main/archives/ 2007/07/the_linus_files.html"

Submission + - Gott: Get to Mars Before 2053 Or Else (nytimes.com)

An anonymous reader writes: The NY Times has a piece in which J. Richard Gott III claims we most likely have only 46 years remaining to get off the planet, and that other possible civilizations in the galaxy missed the window. From the article: "The sobering facts," Dr. Gott says, "are that in a 13.7 billion-year-old universe, we've only been around 200,000 years, and we're only on one tiny planet. The Copernican answer to Enrico Fermi's famous question — Where are the extraterrestrials? — is that a significant fraction must be sitting on their home planets."

OLPC Has Kill-Switch Theft Deterrent 138

Sid writes "Ars Technica reports that the One Laptop Per Child (OLPC) XO has an anti-theft daemon in the OS that can be used to remotely disable machines, much like WGA. The Project added the kill switch at the behest of a few countries concerned about laptop theft. From the report, 'OLPC has responded to such concerns by developing an anti-theft daemon that the project claims cannot be disabled, even by a user with root access. Participating countries can then provide identifying information such as a serial number to a given country's OLPC program oversight entity, which can then disable the devices in certain scenarios.'"

Submission + - Cold Fusion Reborn?

Icarus1919 writes: New Scientist reports that the scientist who discovered a possible fusion reaction by bombarding a solvent with neutrons and sonic waves (known as cold fusion because you don't have to deal with those sun-like temperatures and magnetic fields) has recently been exonerated of accusations of scientific misconduct Purdue University following the verification of his results by another scientist. Is cold fusion back?

Submission + - Topcoder 2007 announced - marathon added

chrisg_chrisg writes: ""TopCoder is thrilled to announce the 2007 TopCoder Open, sponsored by AOL and $260,000 in prize money."
The link to the competition homepage: http://www.topcoder.com/tc?module=Static&d1=tourna ments&d2=tco07&d3=about

There are 4 competitions:
Algorithm (corresponding to SRMs)
Component (don't know much about those)
Marathon (a much welcome addition)
Studio (a chance for graphic and web designers too to become rich and famous..)
Apparently you can participate in more than one competition.

See you there, I'm "chrisg" in the marathon competitions :)
If you don't have a topcoder account, you can get one before registering to the competition."

Submission + - Hard Disk Study Leaves Google Surprised

bugg_tb writes: The BBC is reporting on a study performed by Google engineers on regular 'off the shelf' hard drives that Google uses for caching data and how they perform and the likelyhood of them to fail. The author states: "We expected to notice a very strong and consistent correlation between high utilisation and higher failure rates. "However our results appear to paint a more complex picture. First, only very young and very old age groups appear to show the expected behaviour." The report concludes that: there was a clear trend showing "that lower temperatures are associated with higher failure rates". "Only at very high temperatures is there a slight reversal of this trend." You can see the full report here
