+ - 2015 Corvette Valet Mode Recorder illegal in some states->

Submitted by innocent_white_lamb
innocent_white_lamb (151825) writes "The 2015 Corvette has a Valet Mode that records audio and video when someone other than the owner is driving the car. Activating the Valet Mode allows you to record front-facing video as well as capture audio from within the car so you can help keep your Corvette safe when itâ(TM)s in the hands of others.

Well it turns out that recording audio from within the car may be considered a felony in some states that require notice and consent to individuals that they are being recorded and now GM is sending notices out to dealerships and customers alerting them to this fact as well as promising a future update to the PDR system."

+ - The Great Lightbulb Conspiracy 1

Submitted by HughPickens.com
HughPickens.com (3830033) writes "Markus Krajewski reports that today, with many countries phasing out incandescent lighting in favor of more-efficient and pricier LEDs, it’s worth revisiting the history of the Phoebus cartel—not simply as a quirky anecdote from the annals of technology but as a cautionary tale about the strange and unexpected pitfalls that can arise when a new technology vanquishes an old one. Prior to the Phoebus cartel’s formation in 1924, household light bulbs typically burned for a total of 1,500 to 2,500 hours; cartel members agreed to shorten that life span to a standard 1,000 hours. Each factory regularly sent lightbulb samples to the cartel’s central laboratory in Switzerland for verification. If any factory submitted bulbs lasting longer or shorter than the regulated life span for its type, the factory was obliged to pay a fine.

Though long gone, the Phoebus cartel still casts a shadow today because it reduced competition in the light bulb industry for almost twenty years, and has been accused of preventing technological advances that would have produced longer-lasting light bulbs. Will history repeat itself as the lighting industry is now going through its most tumultuous period of technological change since the invention of the incandescent bulb. "Consumers are expected to pay more money for bulbs that are up to 10 times as efficient and that are touted to last a fantastically long time—up to 50,000 hours in the case of LED lights. In normal usage, these lamps will last so long that their owners will probably sell the house they’re in before having to change the bulbs," writes Krajewski. "Whether or not these pricier bulbs will actually last that long is still an open question, and not one that the average consumer is likely to investigate." There are already reports of CFLs and LED lamps burning out long before their rated lifetimes are reached. "Such incidents may well have resulted from nothing more sinister than careless manufacturing. But there is no denying that these far more technologically sophisticated products offer tempting opportunities for the inclusion of purposefully engineered life-shortening defects.""

An anonymous reader writes "Fresh research out of the UNC Gillings and JHU Bloomberg schools of public health shows industrial farm workers are carrying livestock-associated, multidrug-resistant staph into local communities for weeks at a time. This problem has grown since its last mention on Slashdot. Unfortunately, massive industrial lobbying continues to neuter government action."

+ - beta still sucks, still getting pushed-> 1

Submitted by Anonymous Coward
An anonymous reader writes "Guys.

Beta has become toxic. It is not better than what you had, the fads aren't that interesting, the changes are if anything shinily counterproductive, you've pushed it so incessantly that you've made it hated, and it's reflecting back to you. You're *still* doggedly flogging this dead horse. Whadayawant, keep on it until your readership will lap it up while mumbling "braaaains"?

There are things you could be doing to improve slashdot, like making it less dependent on javascript to function, like making it function well also when javascript is unavailable and without requiring logging in for punishment, and things like that. Oh, and people with basic grasp of English for editors would be nice too. But beta, beta is not those things.

Let. It. Go."

+ - NVIDIA Is Better For Closed-Source Linux GPU Drivers, AMD Wins For Open-Source->

Submitted by Anonymous Coward
An anonymous reader writes "Phoronix last week tested 65 graphics cards on open source drivers under Linux and the best result was generally with the open source AMD Radeon drivers. This week they put out a 35 graphics card comparison using the proprietary AMD/NVIDIA drivers (with the other 30 cards being too old for the latest main drivers) under Ubuntu 14.04. The winner for proprietary GPU driver support on Linux was NVIDIA, which shouldn't come as much of a surprise given that Valve and other Linux game developers are frequently recommending NVIDIA graphics for their game titles while AMD Catalyst support doesn't usually come to games until later. The Radeon OpenGL performance with Catalyst had some problems, but at least its performance per Watt was respectable. Open-source fans are encouraged to use AMD hardware on Linux while those just wanting the best performance and overall experience should see NVIDIA with their binary driver."

+ - Researchers create jet fuel from water, carbon dioxide, and sunlight->

Submitted by MarkWhittington
MarkWhittington (1084047) writes "Chemistry World reported on Friday that a group of European researchers have made a giant step toward inventing a process that will create jet fuel from sunlight, water and carbon dioxide. If and when the process can be brought to an industrial scale it could make greenhouse gasses, considered a dire problem by some, into a valuable resource. It might even make jet plane travel carbon neutral.

The idea is that at high temperatures, water and carbon dioxide break apart into hydrogen, carbon monoxide and oxygen. Then hydrogen and carbon monoxide combines to become syngas. Then using the well-known Fischer-Tropsch process can be converted into kerosene or gasoline.

The trick has always been to remove the excess oxygen, which tends to make the syngas more explosive and therefore dangerous. The European researchers have hit upon the idea of using cerium oxide. When heated with concentrated sunlight the cerium oxide released oxygen which is piped out. When the syngas is created, the cerium reacts with carbon dioxide and water to produce hydrogen and carbon monoxide, absorbing the excess oxygen. Then the cerium oxide is blasted again with sunlight repeating the cycle."

+ - Do backups on Linux no longer matter?-> 5

Submitted by cogcritter
cogcritter (3614357) writes "In June of 2009, the dump/restore utilities version 0.4b42 for Linux's ext3 filesystem were released. This was the last version where incremental dumps could actually be used. A bug introduced in 0.4b43, one year later, causes restore to fail when processing an incremental backup unless, basically, no directory deletions occurred since the level 0 part of the backup set was taken.

The bug is certainly present in Debian Wheezy, and comments in Debian's defect tracking system suggest that the bug has permeated out into other distros as well.

How can Linux's backup/restore tools for its popular ext2/ext3 filesystem be broken for 3+ years, and nobody seems to care? Does nobody take backups? Or do they not use incremental backups? How many people are going to find themselves scrambling when they next NEED to restore a filesystem, and find themselves in possession of long-broken tools?

Just in case this article is where some hapless sysadmin ends up, the workaround is to go to dump.sf.net, go to the files section, pull down the 0.4b42 version and build it for yourself. For me, I think going forward I'm going to switch to filesystem mirroring using rsync."

+ - NASA to Catalog and Release Its Open Source Codes

Submitted by Anonymous Coward
An anonymous reader writes "By the end of next week, NASA will release a master catalog of over 1,000 software projects it has conducted over the years and will provide instructions on how the public can obtain copies of the source codes. NASA's goal is to eventually 'host the actual software code in its own online repository, a kind of GitHub for astronauts.' Since these are open source codes, anyone can use them for private or commercial purposes without having to pay royalties or copyright fees. Scientists not affiliated with NASA have already adapted some of NASA's software. 'In 2005, marine biologists adapted the Hubble Space Telescope’s star-mapping algorithm to track and identify endangered whale sharks. That software has now been adapted to track polar bears in the arctic and sunfish in the Galapagos Islands.' The Hubble Space Telescope's scheduling software has reportedly also been used to schedule MRIs at hospitals and as control algorithms for online dating services. The possibilities could be endless."

Michael Glasser (3588513) writes "I have used Linux off and on for years, not as my main OS but to keep myself informed, but I had not used KDE much since they went to version 4. I recently played with it some on Mint — and was appalled with what I found. Just on the topic of creating and deleting files I found massive numbers of errors, more than can easily be explained in text: http://youtu.be/N7-fZJaJUv8. It includes inconsistencies, incorrect notifications — including ones that can lead to overwriting data or making you think you already have, and more. How can anyone take these developers seriously when they clearly do not put any thought into their product?"

An anonymous reader writes "Achilleas Tsitroulis of Brunel University, UK, Dimitris Lampoudis of the University of Macedonia, Greece and Emmanuel Tsekleves of Lancaster University, UK, have investigated the vulnerabilities in WPA2 and present its weakness. They say that this wireless security system might now be breached with relative ease by a malicious attack on a network. They suggest that it is now a matter of urgency that security experts and programmers work together to remove the vulnerabilities in WPA2 in order to bolster its security or to develop alternative protocols to keep our wireless networks safe from hackers and malware.
