Security Company Tries To Hide Flaws By Threatening Infringement Suit

Slashdot - Mon, 2014-10-20 23:20
An anonymous reader writes: An RFID-based access control system called IClass is used across the globe to provide physical access controls. This system relies on cryptography to secure communications between a tag and a reader. Since 2010, several academic papers have been released which expose the cryptographic insecurity of the IClass system. Based on these papers, Martin Holst Swende implemented the IClass ciphers in a software library, which he released under the GNU General Public License. The library is useful to experiment with and determine the security level of an access control system (that you own or have explicit consent to study). However, last Friday, Swende received an email from INSIDE Secure, which notified him of (potential) intellectual property infringement, warning him off distributing the library under threat of "infringement action." Interestingly, it seems this is not the first time HID Global has exerted legal pressure to suppress information.

A Look At Orion's Launch Abort System

Slashdot - Mon, 2014-10-20 22:40
An anonymous reader writes: With the construction of Orion, NASA's new manned spacecraft, comes the creation of a new Launch Abort System — the part of the vehicle that will get future astronauts back to Earth safely if there's a problem at launch. The Planetary Society's Jason Davis describes it: "When Orion reaches the apex of its abort flight, it is allowed to make its 180-degree flip. The capsule of astronauts, who have already realized they will not go to space today, experience a brief moment of weightlessness before the capsule starts falling back to Earth, heat shield down. The jettison motor fires, pulling the LAS away from Orion. ... Orion, meanwhile, sheds its Forward Bay Cover, a ring at the top of the capsule protecting the parachutes. Two drogue chutes deploy, stabilizing the wobbling capsule. The drogues pull out Orion's three main chutes, no doubt eliciting a sigh of relief from the spacecraft's occupants."

32 Cities Want To Challenge Big Telecom, Build Their Own Gigabit Networks

Slashdot - Mon, 2014-10-20 21:26
Jason Koebler writes: More than two dozen cities in 19 states announced today that they're sick of big telecom skipping them over for internet infrastructure upgrades and would like to build gigabit fiber networks themselves and help other cities follow their lead. The Next Century Cities coalition, which includes a couple cities that already have gigabit fiber internet for their residents, was devised to help communities who want to build their own broadband networks navigate logistical and legal challenges to doing so.

Rumor: Lenovo In Talks To Buy BlackBerry

Slashdot - Mon, 2014-10-20 19:31
BarbaraHudson writes: The CBC, the Financial Post, and The Toronto Sun are all reporting a possible sale of BlackBerry to Lenovo. From the Sun: "BlackBerry shares rose more than 3% on Monday after a news website said Chinese computer maker Lenovo Group might offer to buy the Canadian technology company. Rumors of a Lenovo bid for BlackBerry have swirled many times over the last two years. Senior Lenovo executives at different times have indicated an interest in BlackBerry as a means to strengthen their own handset business. The speculation reached a crescendo in the fall of 2013, when BlackBerry was exploring strategic alternatives. Sources familiar with the situation however, told Reuters last year that the Canadian government had strongly hinted to BlackBerry that any sale to Lenovo would not win the necessary regulatory approvals due to security concerns. Analysts also have said any sale to Lenovo would face regulatory obstacles, but they have suggested that a sale of just BlackBerry's handset business and not its core network infrastructure might just pass muster with regulators."

Which Android Devices Sacrifice Battery-Life For Performance?

Slashdot - Mon, 2014-10-20 18:50
MojoKid writes: A couple of weeks ago, Futuremark began handing out copies of PCMark for Android to members of the press, in an effort to get its leaderboards filled while the finishing touches were being put on the app. That might give you pause in that the results, generated today, are not going to be entirely accurate when the final version comes out, but that's not the case. Futuremark has encouraged publication of results generated with the benchmark. What makes PCMark for Android useful benchmark is that it not only tests for performance, but also for battery-life and performance combined. As such, you can easily figure out which devices sacrifice battery-life for performance and which ones have a good blend of both. The HTC One M8 really stands out, thanks to its nearly balanced performance/battery-life ratio. A result like that might make you think that neither value could be that great, but that's not the case at all. In fact, the battery-life rating on that phone places far beyond some of the other models, only falling short to the OnePlus One. And speaking of that phone, it becomes obvious with PCMark why it's so hyped-up of late; it not only delivers solid performance, it boasts great battery-life as well.

More Eye Candy Coming To Windows 10

Slashdot - Mon, 2014-10-20 16:47
jones_supa writes Microsoft is expected to release a new build of the Windows 10 Technical Preview in the very near future, according to their own words. The only build so far to be released to the public is 9841 but the next iteration will likely be in the 9860 class of releases. With this new build, Microsoft has polished up the animations that give the OS a more comprehensive feel. When you open a new window, it flies out on to the screen from the icon and when you minimize it, it collapses back in to the icon on the taskbar. It is a slick animation and if you have used OS X, it is similar to the one used to collapse windows back in to the dock. Bah.

Help ESR Stamp Out CVS and SVN In Our Lifetime

Slashdot - Mon, 2014-10-20 16:07
mtaht writes ESR is collecting specifications and donations towards getting a new high end machine to be used for massive CVS and SVN repository conversions, after encountering problems with converting the whole of netbsd over to git. What he's doing now sort of reminds me of holding a bake sale to build a bomber, but he's well on his way towards Xeon class or higher for the work. What else can be done to speed up adoption of git and preserve all the computer history kept in source code repositories? ESR says he'll match funds toward the purchase of the needed hardware, so if you want to help drive him into bankruptcy, now's your chance.

NASA's HI-SEAS Project Results Suggests a Women-Only Mars Crew

Slashdot - Mon, 2014-10-20 15:25
globaljustin writes "Alan Drysdale, a systems analyst in advanced life support and a contractor with NASA concluded, "Small women haven't been demonstrated to be appreciably dumber than big women or big men, so there's no reason to choose larger people for a flight crew when it's brain power you want," says Drysdale. "The logical thing to do is to fly small women." Kate Greene, who wrote the linked article, took part in the first HI-SEAS experiment in Martian-style living, and has some compelling reasons for an all-women crew, energy efficiency chief among them: Week in and week out, the three female crew members expended less than half the calories of the three male crew members. Less than half! We were all exercising roughly the same amount—at least 45 minutes a day for five consecutive days a week—but our metabolic furnaces were calibrated in radically different ways. During one week, the most metabolically active male burned an average of 3,450 calories per day, while the least metabolically active female expended 1,475 calories per day. It was rare for a woman on crew to burn 2,000 calories in a day and common for male crew members to exceed 3,000. ... The calorie requirements of an astronaut matter significantly when planning a mission. The more food a person needs to maintain her weight on a long space journey, the more food should launch with her. The more food launched, the heavier the payload. The heavier the payload, the more fuel required to blast it into orbit and beyond. The more fuel required, the heavier the rocket becomes, which it in turn requires more fuel to launch.
