Mac OS X Problem Puts Up a Block To IPv6 204

An anonymous reader lets us know of an experiment conducted in Norway to determine real-world problems in using IPv6 today (Google translation; Norwegian original). "According to a Norwegian article in digi.no, Redpill Linpro did an experiment with regard to IPv6 on one of the largest online newspapers there (www.vg.no). They added a hidden iframe that pointed to an IPv6-enabled domain to test real-life problems about the reported IPv6 holes. The result was that mainly Mac OS X, older versions of Opera, and a few Linux distributions exhibited problems. For Mac OS X it took 75 seconds to time out before failing back to IPv4." From the consultant's report: "Mac OS X has a problem in that it will prefer 6to4-based IPv6 over IPv4-based connectivity, at least if its local IPv4 address is an RFC 1918-based private address as commonly found in NAT-ed home network environments. This is unfortunate, as 6to4 has shown itself to be much less reliable than IPv4."

Do Car Safety Problems Come From Outer Space? 437

Hugh Pickens writes "As electronic devices are made to perform more and more functions on smaller circuit chips, the systems become more sensitive and vulnerable to corruption from single event upsets. This is especially true of Toyota, which has led the auto industry in its widespread inclusion of electronic controls in the manufacture of their various car models. 'These circuit families store not just data, but their basic function electrically,' says Lloyd W. Massengill, director of engineering at the Vanderbilt Institute for Space and Defense Electronics at Vanderbilt University. 'In the unfortunate event of a particle flipping just the right bit, a circuit configured to carry out a benign action may be reprogrammed to carry out some unintended action.' Denise Chow writes in Live Science that some scientists are pointing to cosmic ray radiation as a plausible mechanism behind the sudden, unexplained acceleration reported to have occurred with the late model Toyotas."

Throttle Shared Users With OS X — Is It Possible? 403

whisper_jeff writes "I work in a design studio where the production director is also the owner's son (translation = he can do no wrong). He is fond of accessing a designer's computer via filesharing and working directly on files off of the designer's computers rather than transferring the files to his computer to work on them there. In so doing, he causes the designer's computer to grind to a near-halt as the harddrive is now tasked with his open/save requests along with whatever the designer is doing. Given that there is no way he's going to change his ways (since he doesn't see anything wrong with it...), I was wondering if there was a way to throttle a user's shared access to a computer (Mac OSX 10.5.8) so that his remote working would have minimal impact on our work. Google searches have revealed nothing helpful (maybe I should Bing it... :) so I was hoping someone with more technical expertise on Slashdot could offer a suggestion."

"Normal" Prions May Protect Myelin 81

thomst writes "Nature Neuroscience just published an online article about the function of 'normal' prions in protecting myelin, the substance that sheathes and protects sensory and motor nerves. The international study (which has 11 authors) concluded that 'normal' (i.e., not mis-folded) prions may form a protective coat around myelin. The researchers found that Prnp -/- mice (mice with the gene for prions knocked out) consistently developed progressive demyelination, inevitably leading to persistent polyneuropathy by 60 weeks of age. Their data suggest that damage to myelin sheaths cause normal prions to cleave, and the resulting prion fragments activate Schwann cells, which are known to play a part in myelin repair. This research might eventually lead to possible treatments for progressive polyneuropathies in humans, including those mediated by Creutzfeldt-Jakob disease, multiple sclerosis, Alzheimer's, and even diabetes."

Google Switching To EXT4 Filesystem 348

An anonymous reader writes "Google is in the process of upgrading their existing EXT2 filesystem to the new and improved EXT4 filesystem. Google has benchmarked three different filesystems — XFS, EXT4 and JFS. In their benchmarking, EXT4 and XFS performed equally well. However, in view of the easier upgrade path from EXT2 to EXT4, Google has decided to go ahead with EXT4."

Windows Server Trusts Samba4 Active Directory 182

Darren Ginter writes "A group of Samba v4 developers recently spent a week in Redmond to work with Microsoft on Active Directory interoperability(?!). The result? Windows Server will now join, trust and replicate a Samba-based Active Directory using Microsoft-native protocols. Although Samba v4 is still in the alpha stages, this is a huge step for open source. Or it could be a trap."

Malaria Vaccine, Via Mosquito 178

CodeShark writes "The AP is reporting that mosquitoes have been used for the first time to deliver anti-malarial vaccine through their bites. According to this article the results were crystal clear: 100% of the vaccinated group acquired immunity, everyone in the non-vaccinated control group did not. Those in the control group and developed malaria when exposed to the parasites later, the vaccinated group did not. Malaria kills nearly a million people per year, mostly children."

Company Denies Its Robots Feed On the Dead 154

Back in January we covered the Energetically Autonomous Tactical Robot, or EATR. The EATR gets its energy by "engaging in biologically-inspired, organism-like energy-harvesting behavior which is the equivalent of eating. It can find, ingest, and extract energy from biomass in the environment ..." So many news outlets picked up the story and ran it with titles alluding to the robot "eating flesh" or even "eating corpses" that a company spokesperson put out a press release saying, "This robot is strictly vegetarian." The statement says in part, "RTI's patent pending robotic system will be able to find, ingest and extract energy from biomass in the environment. Despite the far-reaching reports that this includes 'human bodies,' the public can be assured that the engine Cyclone has developed to power the EATR runs on fuel no scarier than twigs, grass clippings and wood chips — small, plant-based items for which RTI's robotic technology is designed to forage. Desecration of the dead is a war crime under Article 15 of the Geneva Conventions, and is certainly not something sanctioned by DARPA, Cyclone or RTI."

NASA Has the Lost Tapes 256

The Shuttle launch may have been delayed by two days, but NASA has better news to report. caffiend666 writes "As speculated a few weeks ago, NASA has found and is starting to restore the lost Apollo 11 tapes. A Briefing will be held July 16th at the Newseum in Washington to 'release greatly improved video imagery from the July 1969 live broadcast of the Apollo 11 moonwalk... The original signals were recorded on high quality slow-scan TV (SSTV) tapes. What was released to the TV networks was reduced to lower quality commercial TV standards.'"

SSN Required To Buy Palm Pre 543

UltraOne writes "Sprint requires your Social Security number in order to run a credit check before they will allow you to open an account, according to a store manager in Silver Spring, MD. Since Sprint is the exclusive carrier for the Palm Pre, if you are not willing to provide an SSN, you can't buy this product. I believe a full credit check for this level of consumer purchase is a clear example of overkill. I have supplied an SSN when buying a house and renting an apartment, but never for any other consumer purchase. I have purchased my cars with cash so far, so I don't have first-hand experience, but a car loan also seems to be an appropriate place to require an SSN for a credit check. At the very least, Sprint should have an alternative for people who don't want to give out their SSN. I also found the entire experience a powerful argument against exclusive license agreements."

Device Reads Messages From Surface of the Brain 156

Al writes "Technology Review has a story about a start-up company that has developed a more-accurate and less-invasive way to read a patient's thoughts. Neurolutions, based in St Louis, has developed a small implanted device that translates signals recorded from the surface of the brain into computer commands. The device, which is less invasive than implants and more accurate than scalp electrodes, uses a grid of electrodes placed directly on the surface of the brain to monitor electrical activity. This technology is currently used to find the origin of seizures in patients with uncontrolled epilepsy before surgery. But the company says it could also help paralyzed patients control a computer and perhaps prosthetic limbs using their thoughts. Tests involving more than 20 patients have shown that people can quickly learn to move a cursor on a computer screen using their brain activity."

Research Vehicle Reaches the Bottom of the Ocean 165

timothy found BBC coverage of the voyage of the Nereus, which on May 31 dove to the bottom of the Challenger Deep in the Marianas Trench. Only two vehicles have accomplished this feat before, the last 11 years ago. "The unmanned vehicle is remotely operated by pilots aboard a surface ship via a lightweight tether. Its thin, fibre-optic tether to the research vessel Kilo Moana allows the submersible to make deep dives and be highly manoeuvrable. Nereus can also be switched into a free-swimming, autonomous vehicle. ... The Challenger Deep... is the deepest abyss on Earth at 11,000m-deep, more than 2km (1.2 miles) deeper than Mount Everest is high. At that depth, pressures reach 1,100 times those at the surface."

Ridiculous Software Bug Workarounds? 655

theodp writes "Ever get a workaround for a bug from a vendor that's so rigoddamndiculous that there has to be a clueless MBA or an ornery developer behind it? For example, Microsoft once instructed users to wiggle their mouse continuously for several minutes if they wanted to see their Oracle data make it into Excel (yes, it worked!). And more recently, frustrated HP customers were instructed to use non-HP printers as their default printer if they don't want Microsoft Office 2007 to crash (was this demoed in The Mojave Experiment?). Any other candidates for the Lame Workaround Hall of Fame?"
