garg0yle writes "Scientists are repurposing Wiimotes as scientific sensors to help measure wind speed or evaporation from lakes, among other things. At about $40 per unit, the controller is much cheaper than specialized sensors. The scientists are still considering how to add storage and extend the battery life."

swsuehr writes "The Book of Xen: A Practical Guide for the System Administrator provides an excellent resource for learning about Xen virtualization. I frequently need to create test environments for examples that appear in various books and magazine articles (in the interest of full disclosure, I've never written for the publisher of this book). In the days before virtualization that meant finding and piecing together hardware. Like many readers, I've been using virtualization in one form or another for several years, including Xen. This book would've saved hours searching around the web looking for tidbits of information and sifting through what works and doesn't work in setting up Xen environments. The authors have done the sifting for me within the ~250 pages of the book. But far beyond, the authors also convey their experience with Xen using walkthroughs, tips, and recommendations for Xen in the real world." Read on for the rest of Steve's review.

jamie sends in a blog post from MySQL co-founder Monty Widenius calling for help to "save MySQL from Oracle's clutches." While the US DoJ approved Oracle's purchase of Sun back in August, the European Commission has been less forthcoming. Widenius points out that Oracle has been using their customers to put pressure on the EC, and he questions Oracle's commitment to MySQL, saying their vague promises aren't good enough. He writes: "Oracle has NOT promised (as far as I know and certainly not in a legally binding manner): To keep (all of) MySQL under an open source license; Not to add closed source parts, modules or required tools; To not raise MySQL license or MySQL support prices; To release new MySQL versions in a regular and timely manner; To continue with dual licensing and always provide affordable commercial licenses to MySQL to those who needs them (to storage vendors and application vendors) or provide MySQL under a more permissive license; To develop MySQL as an Open Source project; To actively work with the community; Apply submitted patches in a timely manner; To not discriminate patches that make MySQL compete more with Oracle's other products; To ensure that MySQL is improved also in manners that make it compete even more with Oracle's main offering."

An anonymous reader writes "Researchers at the University of Tokyo, led by electrical engineering professor Takao Someya, have created a new kind of low-cost, plastic, flash memory storage device. Although not as dense or stable as its silicon cousin, the plastic flash memory is useful because of its low cost, simple manufacturing process, and potential use in e-paper or other flexible devices. To demonstrate the memory, Someya's group integrated a 676-memory-cell device with a rubber pressure sensor. The flexible sensor-memory device, which is less than 700 micrometers thick, can record pressure patterns and retain them for up to a day."

An anonymous reader writes "The long-time Linux kernel module for block replication over TCP, DRBD, has been accepted as part of the main Linux kernel. Amid much fanfare and some slight controversy, Linus has pulled the DRBD source into the 2.6.33 tree, expected to release February, 2010. DRBD has existed as open source and been available in major distros for 10 years, but lived outside the main kernel tree in the hands of LINBIT, based in Vienna. Being accepted into the main kernel tree means better cooperation and wider user accessibility to HA data replication."

1sockchuck writes "A supercomputing center in Quebec has transformed a huge concrete silo into the CLUMEQ Colossus, a data center filled with HPC clusters. The silo, which is 65 feet high with two-foot thick concrete walls, previously housed a Van de Graaf accelerator dating to the 1960s. It was redesigned to house three floors of server cabinets, arranged so cold air can flow from the outside of the facility through the racks and return via an interior 'hot core.' The construction and operation of the unique facility (PDF) are detailed in a presentation from CLUMEQ."

toruonu writes "Yesterday evening the Large Hadron Collider at CERN for the first time accelerated protons in both directions of the ring to 1.18 TeV. Even though the 1 TeV barrier per beam was first broken a week ago, this marks the first time that the beam was in the machine in both directions at the same time, allowing possibly for collisions at a center of mass energy of 2.36 TeV. Although the test lasted mere minutes, it was enough to have detectors record the very first events at 2.36 TeV. LHC passes Tevatron (the particle collider at Fermilab that operates at 1.96 TeV) and becomes the highest energy particle collider in the world (so far it was effectively just the highest energy storage ring...)"

adeelarshad82 writes to tell us that Fusion Garage seems to be ignoring the drama surrounding the "CrunchPad" and is planning to launch their "JooJoo" tablet this Friday at midnight. Unfortunately, the device will be a long way from the imagined $200 price point, weighing in at a hefty $499. "The JooJoo comes in black and has a capacitive touch screen, enough graphic power to deliver full high-definition video, offline capabilities, and a 4GB solid-state drive, though 'most of the storage is done in the cloud,' Rathakrishnan said. He promised 5 hours of battery life. In a demo during the webcast, the device powered on in about 10 seconds, and showed icons for web-based services like Twitter, Hulu, CNN, and Gmail, though the JooJoo will not come pre-loaded with any apps, Rathakrishnan said. Scroll through them with your finger as you would on the iPhone. In terms of the ownership drama, Rathakrishnan said that TechCrunch editor Arrington has created an 'incomplete and distorted story.'"

storagedude points out this article about one of the perils of digital storage, the author of which "says massive digital archives are threatened by simple bit errors that can render whole files useless. The article notes that analog pictures and film can degrade and still be usable; why can't the same be true of digital files? The solution proposed by the author: two headers and error correction code (ECC) in every file."

1sockchuck writes "NASA has built its Nebula cloud computing platform inside a data center container so it can add capacity quickly, bringing extra containers online in 120 days. Nebula will provide on-demand computing power for NASA researchers managing large data sets and image repositories. 'Nebula has been designed to automatically increase the computing power and storage available to science- and data-oriented web applications as demand rises,' explains NASA's Chris Kemp. NASA has created the project using open source components and will release Nebula back to the open source community. 'Hopefully we can provide a good example of a successful large-scale open source project in the government and pave the way for similar projects in other agencies,' the Nebula team writes on its blog."

Glyn Moody writes "The response to Google's Chromium OS has been rather lukewarm. But suppose it's just part of something much bigger: a netbook computer from Google that would cost absolutely nothing. Because all the apps and data are stored in the cloud, storage requirements would be minimal; screens are getting cheaper, and the emphasis on lean code means that a low-cost processor could be used. Those relatively small hardware costs could then be covered by advertising in the apps — after all, they are just Web pages. Interestingly, Google has not only rolled out advertising to more of its services recently, it has also started running AdSense ads in the desktop application Google Earth. Would you accept a free Google netbook — or is the price you would pay in terms of the company knowing even more about what you do on an hour-by-hour basis just too high?"

bennyboy64 contributes this excerpt from CRN Australia: "The CSIRO will this week launch a new supercomputer which uses a cluster of GPUs [pictures] to gain a processing capacity that competes with supercomputers over twice its size. The supercomputer is one of the world's first to combine traditional CPUs with the more powerful GPUs. It features 100 Intel Xeon CPU chips and 50 Tesla GPU chips, connected to an 80 Terabyte Hitachi Data Systems network attached storage unit. CSIRO science applications have already seen 10-100x speedups on NVIDIA GPUs."

Vigile writes "The new Colossus SSD comes in capacities starting at 256GB and going all the way up to 1TB in a standard 3.5-in hard drive form factor. This larger size was required because the drive actually integrates not one but four Indilinx SSD controllers and three total RAID controllers in a nested RAID-0 array. All of this goodness combines to create an incredibly fast drive that beats most other options in terms of write speeds and is competitive in read tests as well. Using some custom 'garbage collection' firmware, the drive works around the fact that TRIM commands aren't supported in RAID configurations to maintain high speeds through the life of the SSD."

aaaaaaargh! writes "I'm using a laptop with Ubuntu 8.04 for work, a netbook with Ubuntu 9.10 when I'm outside, Mac OS X 10.5 for hobby projects, and Windows XP for gaming. For backups, I'm currently using Jungle Disk and Apple's Time Machine, and I use a local svn repository for my work data. Now I need to frequently exchange and synchronize OpenOffice and Latex files and source code in various cross-platform programming languages between one machine and another. Options range from putting everything online (but Jungle Disk disks seem to be too slow for anything else than backup), storing my data on external media like USB sticks or SD cards, or working with copies by synchronizing folders over the network. I don't want to give my data away to some server outside without strong encryption (controlled by me, including the source code) and external media like USB sticks are a bit too fragile according to my taste. The solution should be reliable, relatively failsafe, as simple as possible, and allow me to continue to use Jungle Disk for backup. So what would you recommend?"

judgecorp writes "UK company Iceotope has launched liquid-cooling technology which it says surpasses what can be done with water or air-cooling and can cut data centre cooling costs by up to 93 percent. Announced at Supercomputing 2009 in Portland, Oregon, the 'modular Liquid-Immersion Cooled Server' technology wraps each server in a cool-bag-like device, which cools components inside a server, rather than cooling the whole data centre, or even a traditional 'hot aisle.' Earlier this year, IBM predicted that in ten years all data centre servers might be water-cooled." Adds reader 1sockchuck, "The Hot Aisle has additional photos and diagrams of the new system."

MojoKid writes "When Fusion-io's first ioDrive product hit the market, it was claimed to be a 'disruptive technology' by some industry analysts, with the potential to set the storage industry on its ear. Of course the first version of the ioDrive was an enterprise-class product that showed the significant potential of PCI Express direct-attached SSD storage, but its cost was such that the mainstream market couldn't possibly justify it, no matter what the upside performance looked like. Then we heard of Fusion-io's more consumer-targeted play, the ioXtreme, that was announced this past summer. Fusion-io has only very recently released these new, lower cost cards to market. The first-ever full performance review of the product over at HotHardware shows the half-height PCI Express X4 cards are capable of a robust 800MB/sec read bandwidth and about 300MB/sec of write bandwidth. The cards particularly excel versus a standard SSD at random read/write requests and even perform relatively well with small block transfers."

Lucas123 writes "A start-up launched a new DVD archive product this week: a disc that it says will hold its data for 1,000 years. The company, Cranberry, says its DiamonDisc product, which can be used in any standard DVD player, is not subject to deterioration from heat, UV rays or material rot due to humidity or other elements because it has no dyes, adhesives or reflective materials like standard DVD discs, and its discs are made from a vastly more durable synthetic stone. Data is laid down on the platter much in the same way as a standard DVD disc, but with DiamonDisc the burner etches much deeper pits. Cranberry said it is also working on producing a Blu-ray version of its 1,000-year disc."

PeterAitch writes "The UK government's Home Office has put a hold on their surveillance project to track details of everybody's email, mobile phone, text, and Web use after being warned of problems with privacy as well as technical feasibility and high costs." Four hours before the above Guardian story was filed, the BBC reported that the same Home Office insisted that it will push ahead with plans "to compel communication service providers to collect and retain records of communications from a wider range of internet sources, from social networks through to chatrooms and unorthodox methods, such as within online games."

MojoKid writes "HotHardware has posted a sneak peek at a new motherboard Asus has coming down the pipe with USB 3.0 and SATA 6G support. The Asus P7P55D-E Premium has a PLX PCI Express Gen 2 switch implementation that connects to NEC USB 3.0 and Marvell SATA 6G controller chips. With a USB 3.0 enabled external hard drive connected to a USB 2.0 port and then to the board's USB 3.0 port, there were some rather impressive gains to observe. When connected to a USB 3.0 port, the external hard drive was about 5 — 6x faster versus connecting over USB 2.0, with total throughput in excess of 130MB/sec. On the other hand, benchmarks with Seagate's new Barracuda XT SATA 6G drive show little performance difference but a burst rate that is off the charts. According to ATTO, there are slight overall performance benefits to be had connecting the drive to the SATA 6G controller, but the deltas were quite small; somewhere in the neighborhood of 5MB/s or so."

DustyShadow writes "In the case In re United States, Judge Mosman ruled that there is no constitutional requirement of notice to the account holder because the Fourth Amendment does not apply to e-mails under the third-party doctrine. 'When a person uses the Internet, the user's actions are no longer in his or her physical home; in fact he or she is not truly acting in private space at all. The user is generally accessing the Internet with a network account and computer storage owned by an ISP like Comcast or NetZero. All materials stored online, whether they are e-mails or remotely stored documents, are physically stored on servers owned by an ISP. When we send an e-mail or instant message from the comfort of our own homes to a friend across town the message travels from our computer to computers owned by a third party, the ISP, before being delivered to the intended recipient. Thus 'private' information is actually being held by third-party private companies."" Updated 2:50 GMT by timothy: Orin Kerr, on whose blog post of yesterday this story was founded, has issued an important correction. He writes, at the above-linked Volokh Conspiracy, "In the course of re-reading the opinion to post it, I recognized that I was misreading a key part of the opinion. As I read it now, Judge Mosman does not conclude that e-mails are not protected by the Fourth Amendment. Rather, he assumes for the sake of argument that the e-mails are protected (see bottom of page 12), but then concludes that the third party context negates an argument for Fourth Amendment notice to the subscribers."
