Unreleased OQO 2+ OLED Version Sells For $6,500
psych787 writes "OQO's product line — much loved by their community at oqotalk — has recently suffered a slow, agonizing death. After dropping warranty repairs, not returning several units sent in, disconnecting phonelines, and leaving trash at their headquarters, a couple of units have survived and found eBay. The last one went for $4.5k. Now the only PC for sale to include an OLED has gone for $6.5k. At that price, perhaps a competitor bought the device to come up with something that meets the same market?"Read more of this story at Slashdot.
Bootkit Bypasses TrueCrypt Encryption
mattOzan writes with this excerpt from H-online: "At Black Hat USA 2009, Austrian IT security specialist Peter Kleissner presented a bootkit called Stoned which is capable of bypassing the TrueCrypt partition and system encryption. The bootkit uses a 'double forward' to redirect I/O interrupt 13h, which allows it to insert itself between the Windows calls and TrueCrypt."Read more of this story at Slashdot.
Cheap, Cross-Platform Electronic Circuit Simulation Software?
dv82 writes "I teach circuits and electronics at the undergraduate level, and have been using the free student demo version of OrCad for schematic capture and simulation because (a) it comes with the textbook and (b) it's powerful enough for the job. Unfortunately OrCad runs only under Windows, and students increasingly are switching to Mac (and some Linux netbooks). Wine and its variants will not run OrCad, and I don't wish to require students to purchase Windows and run with a VM. The only production-quality cross-platform CAD tool I have found so far is McCad, but its demo version is so limited in total allowed nets that it can't even run a basic opamp circuit with a realistic 741 opamp model. gEDA is friendly to everything BUT Windows, and is nowhere near as refined as OrCad. I would like students to be able to run the software on their laptops without a network connection, which eliminates more options. Any suggestions?"Read more of this story at Slashdot.
Toyota Reveals A Humanoid Robot That Can Run
Peter writes "Toyota researchers have unveiled a new humanoid robot that can run at 7 km/h, which is faster than Honda's humanoid robot ASIMO. Toyota's robot can also keep itself balanced when pushed, as shown in the video."Read more of this story at Slashdot.
IBM Uses Call-Detail Records To Identify "Friends"
theodp writes "Big Blue may know what you did last summer. Or at least who you called. In a move out of the NSA's playbook, IBM Research has been scrutinizing the call-detail records of 'one of the largest mobile operators in the world' (PDF). By analyzing who calls whom, and for how long, IBM claims its patent-pending snooping software can now identify circles of 'friends' who tend to exhibit the same profit-threatening behavior. 'We believe that our analysis is a first of its kind that exploits the underlying social network in a telecom call graph,' boasted a team of IBM researchers and a UMD prof. For now, IBM seems to have focused on using the info to see if your friends are churners, so you can be dealt with pro-actively lest you follow their lead and bolt. However, IBM suggests its SNAzzy data mining technology (Social Network Analysis for Telecom Business Intelligence) has a bright future, noting it 'is also capable of analyzing any kind of social network or graph, not just telecom networks.'"Read more of this story at Slashdot.
Generating Fast MD5 Collisions With ATI Video Cards
An anonymous reader writes "Yesterday at Black Hat USA 2009, a talk entitled MD5 Chosen-Prefix Collisions on GPUs (whitepaper) (Both PDFs) presented an implementation written in assembly language for ATI video cards that achieves 1.6 billion MD5 hash/sec, or 2.2 billion MD5 hash/sec with reversing, on an ATI Radeon HD 4850 X2. This is faster than the much-publicized 1.4-1.9 billion hash/sec figure that was supposedly reached on a PlayStation 3 by Nick Breese at Black Hat Europe 2008 (he later noticed an error in his benchmarking tool). Compared to the cluster of 215 PlayStation 3s that was used to create a rogue CA in December 2008, Marc Bevand claimed a cluster of 12 machines with 24 video cards would be a bit faster, consume 5 times less power, and be 10 times cheaper."Read more of this story at Slashdot.
How To Make Electronic Displays With Mood Ring Ink
Soychemist writes "Print some thermochromic ink onto a sheet of paper, put metal heating elements on the other side, and you have a rudimentary color-changing display. Chemists in the Whitesides Group at Harvard think that the devices could be used to provide a simple readout from cheap medical tests and kits that check water for pollutants. In the past year, the same scientists have made a three-cent medical test and improvised a centrifuge with an egg beater. Their aim is to invent useful gizmos with everyday materials."Read more of this story at Slashdot.
Apple Keyboard Firmware Hack Demonstrated
Anonymouse writes with this excerpt from SemiAccurate: "Apple keyboards are vulnerable to a hack that puts keyloggers and malware directly into the device's firmware. This could be a serious problem, and now that the presentation and code (PDF) is out there, the bad guys will surely be exploiting it. The vulnerability was discovered by K. Chen, and he gave a talk on it at Black Hat this year (PDF). The concept is simple: a modern Apple keyboard has about 8K of flash memory, and 256 bytes of working RAM. For the intelligent, this is more than enough space to have a field day. ... The new firmware can do anything you want it to. Chen demonstrated code which, when you put in a password and hit return, starts playing back the last five characters typed in, LIFO. It is a rudimentary keylogger; a proof of concept more than anything else. Since there is about 1K of flash free in the keyboard itself, you can log quite a few keystrokes totally transparently."Read more of this story at Slashdot.
The Ethics of Selling GPLed Software For the iPhone
SeanCier writes "We're a small (two-person) iPhone app developer whose first game has recently been released in the App store. In the process, we've inadvertently stepped in it, bringing up a question of the GPL and free software ethics that I'm hoping the Slashdot community can help us clear up, one way or the other. XPilot, a unique and groundbreaking UNIX-based game from the early/mid nineties, was a classic in its day, but was forgotten and has been dead for years, both in terms of use and development. My college roommate and I were addicted to it at the time, even running game servers and publishing custom maps. As it's fully open source (GPLv2), and the iPhone has well over twice the graphics power of the SGI workstations we'd used in college, we decided it was a moral imperative to port it to our cellphones. In the process, we hoped, we could breathe life back into this forgotten classic (not to mention turning a years-old joke into reality). We did so, and the result was more playable than we'd hoped, despite the physical limitations of the phone. We priced it at $2.99 on the App store (we don't expect it to become the Next Big Thing, but hoped to recoup our costs — such as server charges and Apple's annual $99 developer fee), released the source on our web page, then enthusiastically tracked down every member of the original community we could find to let them know of the hoped-for renaissance. Which is where things got muddy. After it hit the App store, one of the original developers of XPilot told us he feels adamantly that we're betraying the spirit of the GPL by charging for it." Read on for the rest of Sean's question.Read more of this story at Slashdot.
CentOS Administrator Reappears
str8edge sends word that Lance Davis, the CentOS project administrator who had mysteriously gone absent, has now returned and is working with the development team to get things back on track. From their announcement: "The CentOS Development team had a routine meeting today with Lance Davis in attendance. During the meeting a majority of issues were resolved immediately and a working agreement was reached with deadlines for remaining unresolved issues. There should be no impact to any CentOS users going forward. The CentOS project is now in control of the CentOS.org and CentOS.info domains and owns all trademarks, materials, and artwork in the CentOS distributions. We look forward to working with Lance to quickly complete all the agreed upon issues. More information will follow soon."Read more of this story at Slashdot.
Electric Company Wants Monthly Fee For Solar Users
7-Vodka writes "Xcel Energy customers who have their own solar panels are worried about a new fee being proposed by the company. A monthly fee to pay for transmission and distribution of energy would be charged to customers who have solar panels, irrespective of their energy use for the month. An Xcel Energy spokesman said the fee is to ensure that regular customers don't subsidize the 'connectivity fees' for the solar panel customers who don't pay when they generate as much as they use. When pressed, the spokesman admitted that nobody actually pays a 'connectivity fee,' yet they wanted to prevent the mooching from occurring in the future (presumably when they hit everyone with such a fee). He also called the absence of a connectivity fee for solar customers a 'double subsidy' because many solar customers receive rebates to install the panels."Read more of this story at Slashdot.
Original Futurama Cast Seals Deal With Fox
Svippy writes "As we discussed earlier, 20th Century Fox Television was attempting to recast Futurama. As it turns out, this was just part of a big negotiation ploy, and the original cast have now completed their deals to return with the show's new episodes. For those of you who did not follow the story, a chronology of the events and reactions from the cast members are available at Infosphere and Voice Actors in the News. Series creators Matt Groening and David X. Cohen said, 'We are thrilled to have our incredible cast back. The call has already gone out to the animators to put the mouths back on the characters.'"Read more of this story at Slashdot.
FCC Probing Apple, AT&T Rejection of Google Voice
suraj.sun writes with an update to the news from a few days ago about Apple pulling Google Voice apps for the iPhone. Their actions have raised the interest of the FCC, which is now beginning an investigation into the matter. "In a letter sent to Apple, the FCC asked the company why it turned down Google Voice for the iPhone and pulled several other Google Voice-related programs from the iPhone's only sanctioned online mart. The FCC also sent similar letters to both AT&T — Apple's exclusive carrier partner in the US — and Google, asking both firms to provide more information on the issue. The FCC's letter asked Apple whether it rejected Google Voice and dumped other applications on its own, or 'in consultation with AT&T,' and if the latter, to describe the conversations the partners had. In other questions, the FCC asked Apple whether AT&T has any role in the approval of iPhone applications, wants the company to explain how Google Voice differs from any other VoIP software that has been approved, and requested a list of all applications that have been rejected and why."Read more of this story at Slashdot.
A Short History of Btrfs
diegocgteleline.es writes "Valerie Aurora, a Linux file system developer and ex-ZFS designer, has posted an article with great insight on how Btrfs, the file system that will replace Ext4, was created and how it works. Quoting: 'When it comes to file systems, it's hard to tell truth from rumor from vile slander: the code is so complex, the personalities are so exaggerated, and the users are so angry when they lose their data. You can't even settle things with a battle of the benchmarks: file system workloads vary so wildly that you can make a plausible argument for why any benchmark is either totally irrelevant or crucially important. ... we'll take a behind-the-scenes look at the design and development of Btrfs on many levels — technical, political, personal — and trace it from its origins at a workshop to its current position as Linus's root file system.'"Read more of this story at Slashdot.
Apple and the Scalability of Secrecy
RobotsDinner writes "Anil Dash has a thoughtful exploration of Apple's notorious devotion to secrecy, and argues that not only is there a limit to its feasibility, but that recent events show Apple has reached that limit already. 'If the ethical argument is unpersuasive, then focus on the long-term viability of your marketing and branding efforts, and realize that a technology company that is determined to prevent information from being spread is an organization at war with itself. Civil wars are expensive, have no winners, and incur lots of casualties.'"Read more of this story at Slashdot.
