Trailrunner7 writes "A group of researchers is claiming that they've found a root exploit that enables them to jailbreak the BlackBerry PlayBook tablet made by Research In Motion. In a video demonstration of the jailbreak, one of the researchers shows off the ability to change the settings on a PlayBook and says that he also has the ability to install the Android Market app on the tablet."

ChristW writes "Remember OpenMoko's first free and open source phones, the GTA-01 and GTA-02 (also called FreeRunner)? There is a new project called Phoenux. The German company Golden Delicous is building a new main board (called GTA-04) for the GTA01/02 case. The new hardware features a DM3730 (800 MHz) processor, a GTM601W UMTS (HSPA) module, and lots more." Would you pay extra for a phone that comes with a Debian build?

JoeRobe writes "Researchers at Harvard have developed a pneumatically-controlled rubber robot that combines undulation and quadrupedal 'crawling,' allowing it to maintain a low profile while moving. In a paper published in PNAS (abstract), they describe it as a 'soft robot, composed exclusively of soft materials (elastomeric polymers), which is inspired by animals (e.g., squid, starfish, worms) that do not have hard internal skeletons.' The robot is solely powered by relatively low pressure (10 psi), and controlled by 5 pneumatic actuators. The research was funded by DARPA." The paper is also available (not paywalled) from the researchers' project site (PDF), complete with more creepy images of the squidbot.

New submitter Juggler00 writes "I have been running DD-WRT (v24-sp2) on my Linksys WRT54GS for a couple of years now. I'm now finding that the box cannot keep up with the requests/requirements I have for it--it simply does not have the MIPS/horsepower. I am turning to the collective wisdom of the Slashdot community for 2 things: what alternative firmware should I be using (DD-WRT, Tomato, OpenWRT, or something else?) and based on the answer to this question, what is the suggested router to purchase to flash? My software requirements include DynDNS client, DHCP server providing option 66, static IP assignment based on MAC, port forwarding, and basic QoS (bittorrent lowest priority). For hardware, I'm looking for GigE ports and 802.11N (5.8GHz not a requirement)."

MojoKid writes "NVIDIA's new Tegra 3 SoC (System on a Chip) has recently been released for performance reviews in the Asus Eee Pad Transformer Prime Android tablet. Tegra 3 is comprised of a quad-core primary CPU complex with a 5th companion core for lower-end processing requirements and power management. The chip can scale up to 1.4GHz on a single core and 1.3GHz on up to four of its cores, while the companion core operates at 500MHz. It makes for a fairly impressive new tablet platform and offers performance that bests Apple's A5 dual-core processor in more than a few tests. The Asus Eee Pad Transformer Prime with optional keyboard dock and NVIDIA's Tegra 3 is set to be available in volume sometime around December 19th."

Alioth writes "The BBC has an article on the BBC Microcomputer, designed and manufactured by Acorn Computers for the BBC's Computer Literacy project. It is now 30 years since the first BBC Micro came out — a machine with a 2 MHz 6502 — remarkably fast for its day; the Commodore machines at the time only ran at 1MHz. While most U.S. readers will never have heard of the BBC Micro, the BBC's Computer Literacy project has had a huge impact worldwide since the ARM (originally meaning 'Acorn Risc Machine') was designed for the follow-on version of the BBC Micro, the Archimedes, also sold under the BBC Microcomputer label by Acorn. The original ARM CPU was specified in just over 800 lines of BBC BASIC. The ARM CPU now outsells all other CPU architectures put together. The BBC Micro has arguably been the most influential 8 bit computer the world had thanks to its success creating the seed for the ARM, even if the 'Beeb' was not well known outside of the UK."

1sockchuck writes "It's been five years since a landmark study outlined the potential benefits of DC power distribution in data centers. But adoption of DC in data centers remains limited, even as the industry aggressively pursues a wide array of other energy savings strategies. Advocates of DC distribution are hoping a new study will jump start the conversation about DC distribution, which can save energy by eliminating several wasteful AC-to-DC conversions within a data center. Meanwhile, an industry association for DC power adoption, the EMerge Alliance, has formed a new technical standards committee for data centers, and is advancing a 380-volt DC power standard. Will DC distribution ever gain momentum in data centers?"

MojoKid writes "NVIDIA has just launched the GeForce GTX 560 Ti with 448 cores. Though perhaps a bit unimaginative in terms of branding, the new GeForce GTX 560 Ti with 448 cores is outfitted with the same GF110 GPU powering high-end GeForce GTX 570 and GTX 580 cards, but with a couple of its streaming multiprocessors fused off. The card has 448 CUDA cores arranged in 14 SMs, with 56 texture units and 40 ROPs. Reference specifications call for a 732MHz core clock with 1464MHz CUDA cores. 1.2GB of GDDR5 memory is linked to the GPU via a 320-bit bus and the memory is clocked at an effective 3800MHz data rate. Performance-wise, the new GPU proved to be about 10 to 15 percent faster than the original GeForce GTX 560 Ti and a few percentage points slower than the GeForce GTX 570."

MrSeb writes with an excerpt from an Extreme Tech story on the recent wild speculation about AMD abandoning x86: "Recent subpar CPU launches and product cancellations have left AMD in an ugly position, but reports that the company is preparing to jettison its x86 business are greatly exaggerated and wildly off base. Yesterday, Mercury News ran a report on AMD's struggles to reinvent itself and included this quote from company spokesperson Mike Silverman: 'We're at an inflection point. We will all need to let go of the old 'AMD versus Intel' mind-set, because it won't be about that anymore.' When we contacted Silverman, he confirmed that the original statement has been taken somewhat out of context and provided additional clarification. 'AMD is a leader in x86 microprocessor design, and we remain committed to the x86 market. Our strategy is to accelerate our growth by taking advantage of our design capabilities to deliver a breadth of products that best align with broader industry shifts toward low power, emerging markets and the cloud.' The larger truth behind Silverman's statement is that no matter what AMD does, it's not going to be 'AMD versus Intel' anymore — it's going to be AMD vs. Qualcomm, TI, Nvidia, and Intel."

a_hanso writes "Hard drives that combine a traditional spinning platter for mass storage and solid state flash memory for frequently accessed data have always been an interesting concept. They may be slower than SSDs, but not by much, and they are a lot cheaper gigabyte-for-gigabyte. CNET's Harry McCracken speculates on how soon such drives may become mainstream: 'So why would the new Momentus be more of a mainstream hit than its predecessor? Seagate says that it's 70 percent faster than its earlier hybrid drive and three times quicker than a garden-variety, non-hybrid disk. Its benchmarks for cold boots and application launches show the new drive to be just a few seconds slower than a SSD. Or, in some cases, a few seconds faster. In the end, hybrid drives are compromises, neither as cheap as ordinary drives — you can get a conventional 750GB Momentus for about $150 — nor as fast and energy-efficient as SSDs.'"

Lucas123 writes "President Obama this week issued a directive to all federal agencies to upgrade records management processes from paper-based systems that have been around since President Truman's administration to electronic records systems with Web 2.0 capabilities. Agencies have four months to come up with plans to improve their records keeping. Part of the directive is to have the National Archives and Records Administration store all long-term records and oversee electronic records management efforts in other agencies. Unfortunately, NARA doesn't have a stellar record itself (PDF) in rolling out electronic records projects. Earlier this year, due to cost overruns and project mismanagement, NARA announced it was ending a 10-year effort to create an electronic records archive."

itwbennett writes "Eurogamer published a piece on a rumored Kinect 2 system that will most likely launch with the next iteration of the Xbox line, which might be sometime between late 2012 and 2014. Eurogamer says this new Kinect won't be hobbled by the limitations of the USB 2.0 port that the current Kinect uses; instead the hardware will be designed to give the new Kinect a faster pipeline to the system's internals. What this means, says blogger Peter Smith is that 'not only can Kinect 2 read finger movements (high on the wish-list for the current hardware) but it can read lips, too. I don't think they mean this in the sense that it can extrapolate what you're saying from your lip movements, but that it can tell who in a room is speaking by matching lip movement to audio input.'"

New submitter rcoxdav writes "Researchers have found that the upgradeable firmware on some laser printers can be easily updated and compromised. The updated firmware could then be used to do anything from overheating the printer to compromising a network. Quoting: 'In one demonstration of an attack based on the flaw, Stolfo and fellow researcher Ang Cui showed how a hijacked computer could be given instructions that would continuously heat up the printer’s fuser – which is designed to dry the ink once it’s applied to paper – eventually causing the paper to turn brown and smoke. In that demonstration, a thermal switch shut the printer down – basically, causing it to self-destruct – before a fire started, but the researchers believe other printers might be used as fire starters, giving computer hackers a dangerous new tool that could allow simple computer code to wreak real-world havoc.'"

An anonymous reader writes "I am required to back up and wipe several hundred computers. Currently, this involves booting up each machine, running a backup script, turning the machine off, booting off a pendrive, and running some software that writes 0s to the drive several times. I was wondering if there was a faster solution. Like a server on an isolated network with a switch where I could just connect the computers up, turn them on and get the server to back up the data and wipe the drives." How would you go about automating this process?

mikejuk writes "Are we getting closer to really effective volumetric 3D display technology? A new display, designed in Russia, uses cold fog and a laser projector to create a volumetric 3D image that you can touch. A tracking device (no, it's not a Kinect) is used to detect the user's hand and moves the virtual objects in response. There have been cold fog 3D displays before, but this one has a reasonable resolution and looks near to being a finished product that could be on sale soon. Estimated price? Between $4000 and $30,000."

Zothecula writes with an excerpt from an article in Gizmag: "The FRAC Centre in Orléans, France will for the first time host an exhibition to be built entirely by flying robots. Titled 'Flight Assembled Architecture,' the six meter-high tower will be made up of 1,500 prefabricated polystyrene foam modules. The installation involves a fleet of quadrocopters that are programmed to interact, lift, transport and assemble the final tower, all the time receiving commands wirelessly from a local control room."

MrSeb writes with an article in Extreme Tech about progress toward getting an AOSP build working on the Nexus S. From the article: "Over the past week, ROM Manager extraordinaire Koush has been frantically working on making a working build of CyanogenMod 9 (Ice Cream Sandwich) for the Samsung Nexus S. The custom ROM, which is built purely from the Android Open Source Project, has now reached 'alpha 11.' All major features are present and no significant bugs remain. It's too early to say that the build is ready for prime time or mission-critical work — the final release of CM9 is due in the new year — but it's certainly stable enough for daily use. The most significant feature, if you can call it that, is that Koush's build of ICS is really very smooth — it's as nimble as Gingerbread, if not more so. Unlike the previous, non-CM build that was released last week, this alpha build of CM9 has every feature enabled, including Google Wallet, and setting a mobile data limit. As usual, the custom ROM is pre-rooted, has ROM Manager installed, and absolutely no bloatware. "

First time submitter fikx writes "How do Slashdotters manage large collections of disks? I'm hoping for a way to manage a large collection of movies that would give me menu type access to the content, and the only consumer device left seems to be the Sony disk changer, which is discontinued. I would have thought that handling disks would have been a solved problem and on sale in many forms, but I guess not. Have Slashdotters found or built solutions? Or has this problem gone the way of the typewriter?"

miller60 writes "Is preventive maintenance on data center equipment not really that preventive after all? With human error cited as a leading cause of downtime, a vigorous maintenance schedule can actually make a data center less reliable, according to some industry experts.'The most common threat to reliability is excessive maintenance,' said Steve Fairfax of 'science risk' consultant MTechnology. 'We get the perception that lots of testing improves component reliability. It does not.' In some cases, poorly documented maintenance can lead to conflicts with automated systems, he warned. Other speakers at the recent 7x24 Exchange conference urged data center operators to focus on understanding their own facilities, and then evaluating which maintenance programs are essential, including offerings from equipment vendors."

Zothecula writes "Do you think that you'll never be able to afford a robot of your own that isn't a toy? Well, if you can get Swiss robot-maker K-Team Corporation to sell you one, chances are you can easily afford a Kilobot — perhaps even a whole bunch of them. Designed and first built by Harvard University's Self-Organizing Systems Research Group, the three-legged robots aren't much larger than the 3.4-volt button cell batteries that power them, and move by vibrating across smooth, flat surfaces. They were created to study robotic swarming behavior, with the intention that tens, hundreds or even thousands of them could be used simultaneously in one experiment. Harvard has just announced that it has licensed the Kilobot technology to K-Team, which will commercially manufacture the robots so that other groups and institutions can purchase them for their own research."
