NSA Agents Leak Tor Bugs To Developers

Fri, 22/08/2014 - 14:29
An anonymous reader writes: We've known for a while that NSA specifically targets Tor, because they want to disrupt one of the last remaining communication methods they aren't able to tap or demand access to. However, not everybody at the NSA is on board with this strategy. Tor developer Andrew Lewman says even as flaws in Tor are rooted out by the NSA and British counterpart GCHQ, other agents from the two organizations leak those flaws directly to the developers, so they can be fixed quickly. He said, "You have to think about the type of people who would be able to do this and have the expertise and time to read Tor source code from scratch for hours, for weeks, for months, and find and elucidate these super-subtle bugs or other things that they probably don't get to see in most commercial software." Lewman estimates the Tor Project receives these reports on a monthly basis. He also spoke about how a growing amount of users will affect Tor. He suggests a massive company like Google or Facebook will eventually have to take up the task of making Tor scale up to millions of users.

The Star That Exploded At the Dawn of Time

Fri, 22/08/2014 - 05:26
sciencehabit writes To probe the dawn of time, astronomers usually peer far away; but now they've made a notable discovery close to home. An ancient star a mere thousand light-years from Earth bears chemical elements that may have been forged by the death of a star that was both extremely massive and one of the first to arise after the big bang. If confirmed, the finding means that some of the universe's first stars were so massive they died in exceptionally violent explosions that altered the growth of early galaxies.

Cause of Global Warming 'Hiatus' Found Deep In the Atlantic

Fri, 22/08/2014 - 03:02
vinces99 writes with news about a study that may account for a slowdown in air temperature rises. Following rapid warming in the late 20th century, this century has so far seen surprisingly little increase in the average temperature at the Earth's surface. More than a dozen theories have now been proposed for the so-called global warming hiatus, ranging from air pollution to volcanoes to sunspots. New research from the University of Washington shows the heat absent from the surface is plunging deep in the north and south Atlantic Ocean, and is part of a naturally occurring cycle. The study is published in Science. Subsurface ocean warming explains why global average air temperatures have flatlined since 1999, despite greenhouse gases trapping more solar heat at the Earth's surface. "Every week there's a new explanation of the hiatus," said corresponding author Ka-Kit Tung, a UW professor of applied mathematics and adjunct faculty member in atmospheric sciences. "Many of the earlier papers had necessarily focused on symptoms at the surface of the Earth, where we see many different and related phenomena. We looked at observations in the ocean to try to find the underlying cause." What they found is that a slow-moving current in the Atlantic, which carries heat between the two poles, sped up earlier this century to draw heat down almost a mile (1,500 meters). Most previous studies focused on shorter-term variability or particles that could block incoming sunlight, but they could not explain the massive amount of heat missing for more than a decade.

Scientists Developing Remote-Control Cyborg Moths

Fri, 22/08/2014 - 01:30
Zothecula writes We've been hearing a lot about the development of tiny flying sensor-equipped robots, that could be sent into areas such as disaster sites to seek out survivors or survey the damage. However, why go to the trouble of designing those robots from scratch, when there are already ready-made insects that are about the right size? That's the thinking behind research being conducted at North Carolina State University, which is aimed at converting moths into "biobots".

Latest Wikipedia Uproar Over 'Superprotection'

Thu, 21/08/2014 - 23:25
metasonix writes: As if the problems brought up during the recent 2014 Wikimania conference weren't enough, now Wikipedia is having an outright battle between its editor and administrator communities, especially on the German-language Wikipedia. The Wikimedia Foundation, currently flush with cash from its donors, keeps trying to force flawed new software systems onto the editor community, who has repeatedly responded by disabling the software. This time, however, Foundation Deputy Director Erik Moeller had the bright idea to create a new level of page protection to prevent the new software from being disabled. "Superprotection" has resulted in an outright revolt on the German Wikipedia. There has been subsequent coverage in the German press, and people have issued demands that Moeller, one of Wikipedia's oldest insiders, be removed from his job. One English Wikipedia insider started a change.org petition demanding the removal of superprotection."

The 2014 Hugo Awards

Thu, 21/08/2014 - 15:09
Dave Knott writes: WorldCon 2014 wrapped up in London this last weekend and this year's Hugo Award winners were announced. Notable award winners include: Best Novel: Ancillary Justice by Ann Leckie Best Novelette: "The Lady Astronaut of Mars" by Mary Robinette Kowal Best Novella: "Equoid" by Charles Stross Best Short Story: "The Water That Falls on You from Nowhere" by John Chu Best Graphic Story: "Time" by Randall Munroe Best Dramatic Presentation (Long Form): Gravity written by Alfonso Cuarón & Jonás Cuarón, directed by Alfonso Cuarón Best Dramatic Presentation (Short Form): Game of Thrones: "The Rains of Castamere" written by David Benioff & D.B. Weiss, directed by David Nutter The results of this year's awards were awaited with some some trepidation in the SF community, due to well-documented attempts by some controversial authors to game the voting system. These tactics appear to have been largely unsuccessful, as this is the fourth major award for the Leckie novel, which had already won the 2013 BSFA, 2013 Nebula and 2014 Clarke awards.

Study: Ad-Free Internet Would Cost Everyone $230-a-Year

Thu, 21/08/2014 - 14:27
Several readers sent word of research into the cost of internet content without ads. They looked at the amount of money spent on internet advertising last year in the U.K., and compared it to the number of U.K. internet users. On average, each user would have to pay about £140 ($230) to make up for the lost revenue of an ad-free internet. In a survey, 98% of consumers said they wouldn't be willing to pay that much for the ability to browse without advertisements. However, while most consumers regard ads as a necessary trade-off to keep the internet free, they will go to great lengths to avoid advertising they do not wish to see. Of those surveyed, 63 per cent said they skip online video ads 'as quickly as possible' – a figure that rises to 75 per cent for 16-24 year olds. Over a quarter of all respondents said they mute their sound and one in five scroll away from the video. 16 per cent use ad blocking software and 16 per cent open a new browser window or tab.

Calif. Court Rules Businesses Must Reimburse Cell Phone Bills

Thu, 21/08/2014 - 13:45
New submitter dszd0g writes The Court of Appeal of the State of California has ruled in Cochran v. Schwan's Home Service that California businesses must reimburse employees who BYOD for work. "We hold that when employees must use their personal cell phones for work-related calls, Labor Code section 2802 requires the employer to reimburse them. Whether the employees have cell phone plans with unlimited minutes or limited minutes, the reimbursement owed is a reasonable percentage of their cell phone bills." Forbes recommends businesses that require cell phone use for employees either provide cell phones to employees or establish forms for reimbursement, and that businesses that do not require cell phones establish a formal policy.

China Pulls Plug On Genetically Modified Rice and Corn

Thu, 21/08/2014 - 05:25
sciencehabit writes China's Ministry of Agriculture has decided not to renew biosafety certificates that allowed research groups to grow genetically modified (GM) rice and corn. The permits, to grow two varieties of GM rice and one transgenic corn strain, expired on 17 August. The reasoning behind the move is not clear, and it has raised questions about the future of related research in China.

How Argonne National Lab Will Make Electric Cars Cheaper

Thu, 21/08/2014 - 03:09
ashshy writes Argonne National Lab is leading the charge on next-generation battery research. In an interview with The Motley Fool, Argonne spokesman Jeff Chamberlain explains how new lithium ion chemistries will drive down the cost of electric cars over the next few years. "The advent of lithium ion has truly enabled transportation uses," Chamberlain said. "Because if you remember your freshman chemistry, you think of the periodic table -- lithium is in the upper left-hand corner of the periodic table. Only hydrogen and helium are lighter on an atomic basis."

Tor Browser Security Under Scrutiny

Wed, 20/08/2014 - 21:20
msm1267 writes: The keepers of Tor commissioned a study testing the defenses and viability of their Firefox-based browser as a privacy tool. The results (PDF) were a bit eye-opening since the report's recommendations don't favor Firefox as a baseline for Tor, rather Google Chrome. But Tor's handlers concede that budget constraints and Chrome's limitations on proxy support make a switch or a fork impossible.

Linus Torvalds: 'I Still Want the Desktop'

Wed, 20/08/2014 - 20:37
darthcamaro writes: Linux has clawed its way into lots of places these days. But at the LinuxCon conference in Chicago today Linus Torvalds was asked where Linux should go next. Torvalds didn't hesitate with his reply. "I still want the desktop," Torvalds said, as the audience erupted into boisterous applause. Torvalds doesn't see the desktop as being a kernel problem at this point, either, but rather one about infrastructure. While not ready to declare a "Year of the Linux Desktop" he still expects that to happen — one day.

Researchers Find Security Flaws In Backscatter X-ray Scanners

Wed, 20/08/2014 - 19:55
An anonymous reader writes: Researchers from UC San Diego, University of Michigan, and Johns Hopkins say they've found security vulnerabilities in full-body backscatter X-ray machines deployed to U.S. airports between 2009 and 2013. In lab tests, the researchers were able to conceal firearms and plastic explosive simulants from the Rapiscan Secure 1000 scanner, plus modify the scanner software so it presents an "all-clear" image to the operator even when contraband was detected. "Frankly, we were shocked by what we found," said lead researcher J. Alex Halderman. "A clever attacker can smuggle contraband past the machines using surprisingly low-tech techniques."

Helsinki Aims To Obviate Private Cars

Wed, 20/08/2014 - 19:08
New submitter NBSCALIDBA writes: Eeva Haaramo reports on Helsinki's ambitious plan to transform city transportation. From on-demand buses to city bikes to Kutsuplus mini-transport vans, the Finnish capital is trying to change the whole concept of getting around in a city. "Under the plan, all these services will be accessed through a single online platform. People will be able to buy their transport in service packages that work like mobile phone tariffs: either as a complete monthly deal or pay as you go options based on individual usage. Any number of companies can use the platform to offer transport packages, and if users find their travel needs change, they'll be able to switch packages or moved to a rival with a better deal."

Google Receives Takedown Request Every 8 Milliseconds

Wed, 20/08/2014 - 17:43
Via TorrentFreak comes news that Google is now being asked to remove one million links per day (or an average of one takedown notice every 8ms). In 2008, they received one takedown request approximately every six days. From the article: The massive surge in removal requests is not without controversy. It’s been reported that some notices reference pages that contain no copyrighted material, due to mistakes or abuse, but are deleted nonetheless. Google has a pretty good track record of catching these errors, but since manual review of all links is unachievable, some URLs are removed in error. ... The issue has also piqued the interest of U.S. lawmakers. Earlier this year the House Judiciary Subcommittee had a hearing on the DMCA takedown issue, and both copyright holders, Internet service providers, and other parties are examining what they can do to optimize the process. In the meantime, the number of removal requests is expected to rise and rise, with 10 million links per week being the next milestone.

Qt Upgrades From LGPLv2.1 to LGPLv3

Wed, 20/08/2014 - 16:29
Digia has announced that existing Qt modules will now be covered under the LGPLv3 in addition to the LGPLv2.1, GPLv3, and the enterprise (proprietary) license. New modules will be dropping LGPLv2.1 and GPLv3+ and be released under the LGPLv3 and GPLv2+ instead. This should be a good move: new Qt modules will be Apache license compatible, LGPLv3 code can trivially be converted to GPLv3, and Digia is even releasing a few modules it intended to make proprietary as Free Software. The KDE Free Qt Foundation is on board. The move was made because of device vendors exploiting a loophole in the GPLv2/LGPLv2.1 that denied users the right to modify Qt or write their own applications. Digia has some self-interest as well, since those vendors were exploiting the tivoization loophole to avoid buying enterprise licenses. From the announcement: We also consider locked-down consumer devices using the LGPL’ed version of Qt to be harmful for the Qt ecosystem. ... Because of this, we are now adding LGPL v3 as a licensing option to Qt 5.4 in addition to LGPL v2.1. All modules that are part of Qt 5.3 are currently released under LGPL v2.1, GPL v3 and the commercial license. Starting with Qt 5.4, they will be released under LGPL v2.1, LGPL v3 and the commercial license. ... In Qt 5.4, the new Qt WebEngine module will be released under LGPL v3 in the open source version and under a LGPLv2.1/commercial combination for Qt Enterprise customers. ... Adding LGPLv3 will also allow us to release a few other add-ons that Digia before intended to make available solely under the enterprise license. ... The first module, called Qt Canvas3D, will give us full WebGL support inside Qt Quick. ... The second module is a lightweight WebView module ... There is a final add-on that will get released under LGPL v3. This module will give native look and feel to the Qt Quick Controls on Android. This module can’t be released under LGPL v2.1, as it has to use code that is licensed under Apache 2.0, a license that is incompatible with LGPL v2.1, but compatible with LGPL v3.
