Submission + - Easy-To-Clean Membrane Separates Oil From Water->

ckwu writes: A steel mesh with a novel self-cleaning coating can separate oil and water, easily lifting oil from an oil-water mixture and leaving the water behind. Unlike existing oil-water separation membranes, if the coated mesh gets contaminated with oil, it can be simply rinsed off with water and reused, without needing to be cleaned with detergents. The team was able to use the mesh to lift crude oil from a crude oil-seawater mixture, showcasing the feasibility of oil-spill cleanup. The membrane could also be used to treat oily wastewater and as a protective barrier in industrial sewer outlets to avoid oil discharge.

Submission + - Police Body Camera Business All About The Video Evidence Storage->

Lucas123 writes: Body cameras are the fastest growing segment of the police video camera business. The two largest police body camera manufacturers today — Taser and VieVu — say they've shipped devices to 41% of the nation's 18,000 police departments. But, the hardware is only the basis for the real business: video evidence storage. Last year, Taser's gross profit margins on hardware were 15.6%; the gross margins for video storage were 51%, according to Glenn Mattson, who follows Taser as an equity analyst for Ladenburg Thalmann. "There's no contest. They don't care about making money on the cameras," Mattson said. As of the first quarter of this year, more than a petabyte of police video has been uploaded to Taser's Evidence.com service. Just one of VieVu's clients, the Oakland PD, has uploaded more than a million police videos. The cost of storage, however, is so high that police departments have been forced to determine strict retention policies, that in some cases may effect the long-term handling of evidence. In Birmingham, Ala., for example, where they've deployed 300 cameras and hope to double that this year, the the video cameras themselves cost about $180,000, but the department's total outlay for a five-year contract including cloud storage with Taser will be $889,000.

Submission + - Teenage boy placed on police register after 'sexting' naked Snapchat ->

Ewan Palmer writes: A teenage boy has had a crime of making and distributing indecent images recorded against him after he sent a naked picture of himself to one of his female classmates. The 14-year-old was not formally arrested after he sent the explicit image to girl of the same age via Snapchat.

The police file against the boy will now remain active for 10 years, meaning any future employer conducting an advanced Criminal Records Bureau check will be aware of the incident.

However, it is not clear whether a police file was recorded for the girl who saved and shared the image. Under new legislation, if she had been over 18, the girl could have been convicted under the so called "revenge porn" law in the UK.

Wikipedia Blocks Hundreds of Accounts Doing Paid Editing 142

jan_jes writes: After weeks of investigation, Wikipedia has blocked 381 user accounts for "black hat" editing. The reason for the ban is that the accounts were engaged in undisclosed paid advocacy — the practice of accepting or charging money to promote external interests on Wikipedia without revealing their affiliation, in violation of Wikimedia's Terms of Use. In addition to blocking the 381 "sockpuppet" account, the editors deleted 210 articles created by these accounts.

Submission + - Browser Makers to Sever RC4 Support in Early 2016->

msm1267 writes: Google, Microsoft and Mozilla today announced they’ve settled on an early 2016 timeframe to permanently deprecate the shaky RC4 encryption algorithm in their respective browsers.

Mozilla said Firefox's shut-off date will coincide with the release of Firefox 44 on Jan. 26. Google and Microsoft said that Chrome and Internet Explorer 11 and Microsoft Edge respectively will also do so in the January-February timeframe.

Practical attacks against RC4 are growing increasingly practical, rendering the algorithm more untrustworthy by the day.

Submission + - LLVM 3.7 Delivers OpenMP 3.1 Support, ORC JIT API, New Optimizations->

An anonymous reader writes: LLVM 3.7 was released today as the newest six-month update. LLVM 3.7 has OpenMP 3.1 support via Clang, a new On-Request Compilation (ORC) JIT API, the Berkeley Packet Filter (BPF) back-end was added, the AMDGPU back-end now supports OpenGL 4.1 when paired with Mesa 11.0, and many other functional changes. Early benchmarks against GCC show its performance quite competitive with GCC5, even superior in some workloads, and should be more competitive in scientific applications with there now being OpenMP support.

Submission + - Chrome 45 Launches, Automatically Pauses Less Important Flash Content Like Ads

An anonymous reader writes: Google today launched Chrome 45 for Windows, Mac, Linux, and Android with some expected changes and new developer tools. You can update to the latest version now using the browser’s built-in silent updater or download it directly from google.com/chrome. First and foremost, Chrome now automatically pauses less important Flash content (rolling out gradually, so be patient). This has been a longtime coming from both Google and Adobe, with the goal to make Flash content more power-efficient in Chrome: In March, a setting was introduced to play less Flash content on the page, but it wasn’t turned on by default, and in June, the option was enabled in the browser’s beta channel. Now it’s being turned on for everyone.

Submission + - Lack of sleep puts you at higher risk for colds, first experimental study finds->

sciencehabit writes: Moms and sleep researchers alike have stressed the importance of solid shuteye for years, especially when it comes to fighting off the common cold. Their stance is a sensible one—skimping on sleep weakens the body’s natural defense system, leaving it more vulnerable to viruses. But the connection relied largely on self-reported, subjective surveys—until now. For the first time, a team of scientists reports that they have locked down the link experimentally, showing that sleep-deprived individuals are more than four times more likely to catch a cold than those who are well-rested.

Submission + - Pile of Bugs in Belkin Routers Allow DNS Spoofing, Credential Theft 1

Trailrunner7 writes: The CERT/CC is warning users that some Belkin home routers contain a number of vulnerabilities that could allow an attacker to spoof DNS responses, intercept credentials sent in cleartext, access the web management interface, and take other actions on vulnerable routers.

The vulnerabilities affect the Belkin N600 DB Wireless Dual Band N+ router, model F9K1102 v2 with firmware version 2.10.17, and potentially earlier versions of the firmware, as well. The vulnerabilities have not been patched by Belkin, the advisory from the CERT/CC says there aren’t any practical workarounds for them.

“DNS queries originating from the Belkin N600, such as those to resolve the names of firmware update and NTP servers, use predictable TXIDs that start at 0x0002 and increase incrementally. An attacker with the ability to spoof DNS responses can cause the router to contact incorrect or malicious hosts under the attacker’s control,” the CERT/CC advisory says.

Submission + - Red Fireworks Go Green->

An anonymous reader writes: Makers of fireworks and flares have long believed that the beautiful red color in their explosions could be attained only with chlorine-based compounds. But after these ingredients combust, they can transform into cancer-causing chemicals that then fall to the ground. New chlorine-free pyrotechnics could pave the way for a generation of red fireworks and flares that are better for the environment and for people’s health.

Chemists formulated the new explosive by replacing polyvinyl chloride on the old ingredient list with either hexamine, a preservative in citrus washing solutions, or 5-amino-1H-tetrazole, an air-bag propellant.
