snydeq writes "Datacenter operators seeking increased server density may soon turn to power capping, an emerging technology that limits the amount of electricity a server can consume, InfoWorld reports. The practice, which can be applied at the rack level, ensures that no server draws above a set power level, thereby increasing datacenter capacity within a rack-level power envelope by as much as 20 percent, according to a proof-of-concept study at Baidu, China's largest search company. As with powering down servers during off hours, of course, power capping incurs calculated risk, as those in charge of business-critical applications may be reluctant to set power limits below maximum utilization. Yet given IT's need to contend with the permanent energy crisis, the notion of power capping the datacenter could prove advantageous."

igny writes "I have just recently cleaned up my home office, reducing the clutter, but I could not come up with a neat solution to my cable problem. I believe my cable usage is even below average for a slashdotter, but still I have three computers with a bunch of ethernet and power cables, two cellphones, video and photo cables, with several proprietary chargers/AC adapters, printer, two NASes with a couple of external drives, phone, audio system, routers/switches, modem ... Everything requires cables of different kinds. I believe that AC adapters still draw some power even with no device hooked to it. So I organized my power cables by usage with several power strips to turn off adapters which I use less frequently. I am asking for advice from experienced slashdotters. How do you cope with your cable problem? Do you use dedicated tables, shelves, armoire for the cables? I am still looking for a neat, efficient, and safe (I have small kids) solution."

An anonymous reader links to Ars Technica's report that (quoting) "Microsoft today announced that Windows 7 and Windows Server 2008 R2 have hit the Release to Manufacturing (RTM) milestone. The software giant still has a lot of work to do, but the bigger responsibility now falls to OEMs that must get PCs ready, Independent Software Vendors (ISVs) that are testing their new apps, and Independent Hardware Vendors (IHVs) that are preparing their new hardware. The RTM build is 7600, but it is not the same one that leaked less than two weeks ago (7600.16384). We speculated that Microsoft may end up recompiling build 7600 until it is satisfied, but it only took the company one more shot to get it right: 7600.16385 is the final build number. Microsoft refused to share the full build string, but if you trust leaks from a few days ago, it's '6.1.7600.16385.090713-1255,' which indicates that the final build was compiled over a week ago: July 13, 2009, at 12:45pm. This would be in line with the rumored RTM date but it is also the day Microsoft stated that Windows 7 had not yet hit RTM. Although the final build had been compiled, Microsoft still had to put it through testing before christening it as RTM."

eldavojohn writes "Okay, well, maybe not everyone but more than twenty companies (including Apple, Qualcomm, Motorola and Microsoft) are being sued for a generic patent that reads: 'Apparatus and methods for controlling a portable electronic device, such as an MP3 player; portable radio, voice recorder, or portable CD player are disclosed. A touchpad is mounted on the housing of the device, and a user enters commands by tracing patterns with his finger on a surface of the touchpad. No immediate visual feedback is provided as a command pattern is traced, and the user does not need to view the device to enter commands.' Sounds like their may be a few companies using that technology. The suit was filed on July 15th in the favoritest place ever to file patent claim lawsuits: Texas Eastern District Court. It's a pretty classic patent troll; they've been holding this patent since 2003 and they just noticed now that everyone and his dog are using touchpads to control portable electronic devices."

stry_cat writes "Over a year ago ICANN moved to clean up misbehaving registrars like GoDaddy. They released this scary sounding advisory. However, over a year later, problems remain. One company is now publicly complaining. Some of the biggest registrars are slammed for their actions. 'Register.com is one frustrating company. The ICANN policy clearly prohibits blocking a transfer of a domain name that has expired but not yet been deleted. Despite that, a customer trying to transfer a three-day-expired Register.com domain name told us last week that they refused to give him the necessary code to allow him to transfer — unless he pays them to renew it first. ... GoDaddy (and their reseller arm, Wild West Domains) have a different problem: They still block transfers for 60 days after a registrant's contact update, even after the ICANN update specifically prohibited doing so. They freely admit it, too. ... We see a similar problem with many transfers from Network Solutions.'"

ers81239 writes "I've recently become a Linux administrator within the Department of Defense. I am surprised to find out that the DoD actually publishes extensive guidance on minimum software versions. I guess that isn't so surprising, but the version numbers are. Kernel 2.6.30, ntp 4.2.4p7-RC2, OpenSSL 9.8k and the openssh to match, etc. The surprising part is that these are very fresh versions which are not included in many distributions. We use SUSE Enterprise quite a bit, but even openSUSE factory (their word for unstable) doesn't have these packages. Tarballing on this many systems is a nightmare and even then some things just don't seem to work. I don't have time to track down every possible lib/etc/opt/local/share path that different packages try to use by default. I think that this really highlights the trade-offs of stability and security. I have called Novell to ask about it. When vulnerabilities are found in software, they backport the patches into whatever version of the software they are currently supporting. The problem here is that doesn't give me a guarantee that the backport fixes the problem for which this upgrade is required (My requirements say to install version x or higher). There is also the question of how quickly they are providing the backports. I'm hoping that there are 100s of DoD Linux administrators reading this who can bombard me with solutions. How do you balance security with stability?"

alphadogg writes "Inside a plain-looking garage on the Massachusetts Institute of Technology's campus, undergraduate Radu Gogoana and his team of fellow students are working on a project that could rival what major automobile manufacturers are doing. The team's goal is to build an all-electric car with similar performance capabilities of gasoline-only counterparts, which includes a top speed of about 161 kph, a family sedan capacity, a range of about 320 kilometers and the ability to recharge in about 10 minutes. They hope to complete the project, which they chronicle on their blog, by the third quarter of 2010. Each member of MIT's Electric Vehicle Team works almost 100 hours a week on the project they call elEVen. 'Right now the thing that differentiates us is that we're exploring rapid recharge,' Gogoana said during an interview. He said that many of today's electric vehicles take between two to 12 hours to recharge and he doesn't know of any commercially available, rapidly recharging vehicles."

schliz writes "Scientists from the University of York have come up with a new recycling technique that extracts PVA from used LCD panels to create a 'a bioactive sponge.' The technique could allow recovered PVA to be used in pills, wound dressings and tissue scaffolds that aid human tissue regeneration. It could also keep waste LCD screens from incineration or landfill altogether."

The leader is Zeus, with 3.6 million compromised PCs so far. The Zeus Trojan uses key-logging techniques to steal user names, passwords, account numbers and credit card numbers, and it injects fake HTML forms into online banking login pages to steal user data. At the bottom of the list is Conficker, which despite its celebrity status has compromised just 210,000 US computers so far."

BBCWatcher writes "In CPU news, IBM says that its POWER7 servers will start shipping in the first half of 2010, on schedule or perhaps even a few months early if you believe Wikipedia. Moreover, upgrades from a wide variety of POWER6 models will be mere CPU swaps, with the upgraded servers keeping their same serial numbers. (Bean counters like that.) POWER7 sports up to 8 cores per die, 4 threads per core, a clock speed a Hertz or two above 4 GHz, 45 nm process manufacturing, on-chip DDR3, and up to 1,000 micropartitions per machine. IBM claims that POWER7 will offer about 256 Gflops per die and two to three times the performance per watt as POWER6. IBM wants to keep taking orders now for its POWER6 gear (duh), so its sales reps are allegedly ready and eager to deal on 6-cum-7 packages. And it looks like that cunning plan could work rather well given Sun's Rock CPU cancellation and HP's delay of Tukwila Itanium to 2010. (Is anybody still in the server CPU race except IBM, Intel, and maybe AMD?) In 2006, POWER7 won the contest for a DARPA supercomputing R&D grant of $244 million, so you could say that each US citizen is in for about a dollar already."

BayaWeaver writes "Slate reports that the F-22 Raptor has been cancelled by the Senate. At an estimated price tag of $339 million per aircraft, even the powerful military-industrial-congressional complex couldn't keep this Cold War program alive in these hard times. They look very cool though and have appeared in movies like Hulk and Transformers. But not to worry too much about the future of the military-industrial-congressional complex: the F-35 Lightning II begins production next year! As a side note, in 2007 a squadron of Raptors became deaf, dumb and blind when they flew over the International Date Line."

Mike Lawrie writes "The so-called Canadian DMCA has had a long history. Historically, proposed legislation has favoured the views of CRIA, the Canadian arm of the RIAA almost completely. However, this time around the government is consulting the public before drafting the bill. They have launched a (Linux-based!) website designed to provide a public forum for discussion. Now is the time to speak up."

Michael J. Ross writes "Slow Web page loading can discourage visitors to a site more than any other problem, regardless of how attractive or feature-rich the given site might be. Consequently, many Web developers hope to achieve faster response times using AJAX (Asynchronous JavaScript and XML), since only portion(s) of an AJAX page need to be reloaded. But for many rich Internet applications (RIAs), such potential performance gains can be lost as a result of non-optimized JavaScript, graphics, and CSS files. Steve Souders — a Web performance expert previously at Yahoo and now with Google — addresses these topics in his second book, Even Faster Web Sites: Performance Best Practices for Web Developers." Read on for the rest of Michael's review.

After enjoying several years of popularity, music games seem to be drawing less and less interest from gamers lately. Guitar Hero and Rock Band titles have been conspicuously absent from a list of the 20 best-selling software titles in the past two months, and one report estimates that revenue from those games has dropped by almost half. Analyst Jesse Divnich suggests that there's no longer much room for dramatic improvements in game play, saying, "it would be erroneous to assume that any franchise or brand can grow unless it brings something new to the table. After a while, utility to the gamer will diminish and he/she will surely move on." Nevertheless, the companies are happy to continue to rely on DLC sales while working on new releases. Harmonix is showing off a trailer and a partial set list for The Beatles: Rock Band, and Neversoft has detailed a number of new features and tracks for Guitar Hero 5.

Al writes "Researchers from the University of Connecticut have created a new light-emitting material by doping spun strands of salmon DNA with fluorescent dyes. The material, which is robust because DNA is such a strong polymer, absorbs energy from ultraviolet light and gives off different colors depending on the amounts of dye it contains. A team led by chemistry professor Gregory Sotzing created the new material by mixing salmon DNA with two types of dye, then pumping the solution from a fine needle while a voltage is applied between the needle tip and a grounded copper plate covered with a glass slide. As the liquid jet comes out, it dries and forms long nanofibers that are deposited on the glass slide as a mat. The researchers then spin this nanofiber mat directly on the surface of an ultraviolet LED to make a white-light emitter. The color-tunable DNA material relies on an energy-transfer mechanism between two different fluorescent dyes, and the DNA keeps the dye molecules separated at a distance of 2 to 10 nanometers from each other."
