The BBC reports that researchers have discovered a huge pool of meltwater beneath Greenland's ice sheet, trapped "in the air space between particles of ice, similar to the way that fruit juice stays liquid in a slush drink." From the article, based on research published in Nature Geoscience (abstract): "The scientists say the water is prevented from freezing by the large amounts of snow that fall on the surface of the ice sheet late in the summer. This insulates the water from the air temperatures which are below freezing, allowing the water to persist as liquid all year long. Other researchers believe this discovery may help explain disparities between projections of mass loss by climate models and observations from satellites."

sfcrazy writes "Ironically while Netflix's infrastructure runs on Linux and Open Source technologies, the service doesn't support Linux, the platform. Netflix is available for Mac, Windows, iOS, Android and Chrome OS but not for desktop Linux. One of the reasons could be that Netflix still uses Microsoft's Silverlight which is not supported on Linux. However Linux users have managed to get it to work on their distros. Now openSUSE users can also run Netflix using Pipelight."
A few days ago, we mentioned that the UK's ISP-level censorware software not only does a poor job of its stated job (blocking porn), but blocks at least some sex education sites, too; now, reader badger.foo writes to say that's not all: "It fell to the UK Tories to actually implement the Nanny State. Too bad Nanny Tory does not want kinds to read up on tech web sites such as slashdot.org, or civil liberties ones such as the EFF or Amnesty International. Read on for a small sample of what the filter blocks, from a blocked-by-default tech writer."
McGruber writes "The FBI Supervisory Special Agent who authored the FBI's interrogation manual submitted the document for copyright protection — in the process, making it available to anyone with a card for the Library of Congress to read. The story is particularly mind-boggling for two reasons. First, the American Civil Liberties Union fought a legal battle with the FBI over access to the document. When the FBI relented and released a copy to the ACLU, it was heavily redacted — unlike the 70-plus page version of the manual available from the Library of Congress. Second, the manual cannot even qualify for a copyright because it is a government work. Anything 'prepared by an officer or employee of the United States government as part of that person's official duties' is not subject to copyright in the United States."
theodp writes "What's wrong with this picture?" asked Code.org at its launch earlier this year, lamenting the lack of Computer Science students in a race and gender reference-free infographic. But as the organization has grown via public/private partnerships and inked agreements to drive the CS curriculum for the Chicago and NYC school systems, the same stats webpage has adopted a new gender and racial equity focus, positioning Computer Science education as "a chance to level the playing field" for women, Hispanic and African American students. The new message is consistent with the recently-forged Code.org partnership with the NSF-funded Exploring Computer Science (ECS, "a K-12/university partnership committed to democratizing computer science") and Computer Science Principles (CSP, "a new course under development that seeks to broaden participation in computing and computer science"). According to The Research Behind ECS, an "insidious 'virtual segregation' that maintains inequality" is to blame for keeping the number of African Americans and Latino/as CS students disproportionately low. So, what might the future of Code.org's proposed equity-based U.S. K-12 CS education look like? "Including culturally relevant instructional materials represented a driving focus of our course development," explained ECS Team members who now advise Code.org. "Cultural design tools encourage students to artistically express computing design concepts from Latino/a, African American, or Native American history as well as cultural activities in dance, skateboarding, graffiti art, and more. These types of lessons are important for students to build personal relationships with computer science concepts and applications – an important process for discovering the relevance of computer science for their own life." And — ironically for Code.org — it could mean less coding."
hypnosec writes "Evad3rs, the famous iOS jailbreak team, has announced an iOS 7 jailbreak that will work in all iDevices including iPhone 5S, iPhone 5C and iPad Air running iOS 7.0 through to iOS 7.0.4. The iOS 7 jailbreak was announced without much of a hype, unlike the one for iOS 6. 'Merry Christmas! The iOS 7 jailbreak has been released at http://evasi0n.com/! All donations will go to @publicknowledge, @eff and @ffii,' tweeted evad3rs." Reader FrogBlastTheVentCore adds a note of caution: "They recommend restoring your device to iOS 7.0.4 if it has received OTA updates before attempting to jailbreak."
An anonymous reader writes: "I hope there are a few open source developers on Slashdot who understand this. As a developer who works alone and remotely (while living with my own family) — and is schizophrenic — there would be times I would feel very high (a surge of uncontrollable thoughts), or low because of the kind of failures that some patients with mental illness would have, and because of the emotional difficulty of being physically alone for 8 hours a day. This led me to decide to work physically together with my co-workers. Have you been in this situation before? If you have, how well did you manage it? (Medications are a part of the therapy as well.)"
Jacob Appelbaum isn't shy about his role as a pro-privacy (and anti-secrecy) activist and hacker. A long-time contributor to the Tor project, and security researcher more generally, Appelbaum stood in for the strategically absent Julian Assange at HOPE in 2010, and more recently delivered Edward Snowden's acceptance speech when Snowden was awarded the Government Accountability Project's Whistleblower Prize. Now, he reports, his Berlin apartment appears to have been burglarized, and his computers tampered with. As reported by Deutsche Welle, "Appelbaum told [newspaper the Berliner Zeitung] that somebody had broken into his apartment and used his computer in his absence. 'When I flew away for an appointment, I installed four alarm systems in my apartment,' Appelbaum told the paper after discussing other situations which he said made him feel uneasy. 'When I returned, three of them had been turned off. The fourth, however, had registered that somebody was in my flat - although I'm the only one with a key. And some of my effects, whose positions I carefully note, were indeed askew. My computers had been turned on and off.'" It's not the first time by any means that Appelbaum's technical and political pursuits have drawn attention of the unpleasant variety.
savuporo writes "The two days of DARPA's humanoid robotics challenge are now over. 16 teams entered in three categories — custom built humanoid, DARPA supplied Atlas platform, and a non-humanoid form — and competed in eight different tasks. The all-Japanese SCHAFT team scored 27 out of 32 maximum points, followed by IHMC Robotics and Tartan Rescue, with 20 and 18 points. The tasks included challenges like driving a vehicle, climbing ladders and walls, using handheld tools to cut through walls, etc. All robots had a mix of autonomy and teleoperated controls to accomplish the tasks. Full details on scores can be found here. The eight teams that scored highest will get continued funding from DARPA to compete in the final challenge in 2014. Two NASA teams also entered, and the JPL-built non-humanoid RoboSimian placed 5th, whereas the JSC built and touted 'Valkyrie' came out of competition with zero points. Team SCHAFT and Boston Dynamics (building the Atlas platform) were recently acquired by Google."
An anonymous reader writes "About 2 years ago, Jonas Pfeil, created a Throwable Panorama Ball: A rugged, grapefruit-sized ball with 36 fixed-focus, 2-megapixel digital camera sensors that capture simultaneously when thrown in the air, creating a full spherical panorama of the surrounding scene. Now, an Indiegogo campaign aims to produce the the camera (Now known as Panono) available for about $500. The quality of the sample images is impressive: the resolution is quite good and most importantly, the stitching artifacts are hardly visible."
Hugh Pickens DOT Com writes "Shona Ghosh writes at PC Pro that the final deadline for Windows XP support in April 2014 will act as the starting pistol for developing new exploits as hackers reverse-engineer patches issued for Windows 7 or Windows 8 to scout for XP vulnerabilities. "The very first month that Microsoft releases security updates for supported versions of Windows, attackers will reverse-engineer those updates, find the vulnerabilities and test Windows XP to see if it shares [them]," says Tim Rains, the director of Microsoft's Trustworthy Computing group. Microsoft says that XP shared 30 security holes with Windows 7 and Windows 8 between July 2012 and July 2013. Gregg Keizer says that if a major chunk of the world's PCs remains tied to XP, as seems certain, Microsoft will face an unenviable choice: Stick to plan and put millions of customers at risk from malware infection, or backtrack from long-standing policies and proclamations."

Walking The Walk writes "Canada's spy agency deliberately withheld information from the courts in an effort to do an end-run around the law when it applied for top-secret warrants to intercept the communications of Canadians abroad, a Federal Court judge said Friday. CSIS assured Judge Richard Mosley the intercepts would be carried out from inside Canada, and controlled by Canadian government personnel, court records show. However, Canadian officials then asked for intercept help from foreign intelligence allies without telling the court. 'It is clear that the exercise of the court's warrant issuing has been used as protective cover for activities that it has not authorized,' Mosley wrote in redacted reasons."
SonicSpike writes "Overstock plans to become the first big U.S. online retailer to accept Bitcoin, as Patrick Byrne, the company's libertarian chief executive, warms to the virtual currency as a refuge from government control. Mr Byrne told the Financial Times that Overstock planned to start accepting Bitcoin next year – possibly by the end of the second quarter – a decision that he said was driven mainly by his own political philosophy. 'I think a healthy monetary system at the end of the day isn't an upside down pyramid based on the whim of a government official, but is based on something that they can't control,' Mr Byrne said."
