  • Authorities Reportedly Question McAfee's Ex-girlfriend
    2016-02-13T17:12:00+00:00
    netbuzz writes: While antivirus software pioneer John McAfee is in the media spotlight for his long-shot Libertarian presidential run, law enforcement authorities in Belize and the FBI have just this week reportedly questioned one of his ex-girlfriend's as they continue to investigate the 2012 murder of McAfee's American neighbor. That probe prompted McAfee to flee Belize and eventually land back in the United States. McAfee has steadfastly denied any involvement in the murder.

  • Hertz Is Pulling a Disney

    New submitter wcrowe writes: Hertz is laying off over 200 IT employees, outsourcing the work to IBM India Private Limited, which has filed paperwork for H1-B visas to bring in replacements from overseas. This sounds pretty similar to what Disney did a year ago.

  • Sci-Hub, a Site With Open and Pirated Scientific Papers
    2016-02-13T15:01:00+00:00
    lpress writes: Sci-Hub is a Russian site that seeks to remove barriers to science by providing access to pirated copies of scientific papers. It was established in 2011 by Russian neuroscientist Alexandra Elbakyan, who could not afford papers she needed for her research and it now claims to have links to 48 million pirated and open papers. I tried it out and found some papers and not others, but it provides an alternative for researchers who cannot afford access to paid journals. After visiting this site, one cannot help thinking of the case of Aaron Swartz, who committed suicide as a result of prosecution for his attempt to free scientific literature.

  • Even Einstein Doubted His Gravitational Waves
    2016-02-13T13:28:00+00:00
    Flash Modin writes: In 1936, twenty years after Albert Einstein introduced the concept, the great physicist took another look at his math and came to a surprising conclusion. 'Together with a young collaborator, I arrived at the interesting result that gravitational waves do not exist, though they had been assumed a certainty to the first approximation,' he wrote in a letter to friend Max Born. Interestingly, his research denouncing gravitational waves was rejected by Physical Review Letters, the journal that just published proof of their existence. The story shows that even when Einstein's wrong, it's because he was already right the first time.

  • BT Announces Free Service To Screen Nuisance Callers
    2016-02-13T11:39:00+00:00
    An anonymous reader writes: British telco BT is launching a free landline service for UK customers which promises to divert millions of unwanted calls. A dedicated team at BT will monitor calls made to UK numbers, across its network of over 10 million domestic landlines, to identify suspicious patterns, which could help to filter out nuisance callers. The flagged numbers will then be directed to a junk voicemail box. The company has estimated that the voicemail 'net' will catch up to 25 million cold calls every week. It explained that to achieve this success rate, it would be deploying enormous amounts of compute power to monitor and analyse large amounts of data in real-time.

    An anonymous reader writes: The website of the British Association for Counseling & Psychotherapy has been hit by a variant of the CTB-Locker ransomware. While the ransomware proclaims itself to be CTB-Locker, there are a ton of clues that reveal this may be a fake and this is actually the first ever ransomware family created to target websites and not computers.

  • New Metallic Glass Creates Potential For Smart Windows
    2016-02-13T06:12:00+00:00
    frank249 writes: A B.C. engineering lab has created metal-coated glass that transmits up to 10 per cent more light than conventional glass and opens the door to windows that function as electronics. The most immediate use of the technology is to create windows that can be programmed to absorb or reflect heat, depending on the needs of a building's occupants. Adding electronic control to windows will allow you to change the amount of light and heat passing through to more effectively use the energy provided by the sun naturally, Lead investigator Kenneth Chau credit films like Iron Man or Star Trek with providing them inspiration. "There is a dream that we can make glass smarter," he said. "These films give us concepts to strive for; the hard work is uncovering the science to make it happen." All those hours spent watching Star Trek are now starting to look like a "pretty good investment," he said. The results were published this week in the journal Scientific Reports.

  • LinkedIn Is Open Sourcing Their Testing Frameworks
    2016-02-13T03:24:00+00:00
    destinyland writes: LinkedIn is open sourcing their testing frameworks, and sharing details of their revamped development process after their latest app required a year and over 250 engineers. Their new paradigm? "Release three times per day, with no more than three hours between when code is committed and when that code is available to members," according to a senior engineer on LinkedIn's blog. This requires a three-hour pipeline where everything is automated, from committing code to releasing it into production, along with automated analyses and testing. "Holding ourselves to this constraint ensures we won't revert to using manual validation to certify our releases."

  • Ubisoft Talks Splitscreen and the Division
    2016-02-13T00:39:00+00:00
    SlappingOysters writes: Ubisoft's next entry in the Tom Clancy series is pushing at the boundaries of three genres, mixing the RPG, the squad-based shooter and the MMO into The Division. The game features drop-in, drop-out co-op in a near-future, post-pandemic New York that seamlessly allows players to transition from PvE to PvP environments without any menus or lobbies. However, despite its co-op gameplay, The Division does not support splitscreen. Finder.com.au recently ran an extensive hands-on with the game, as well as an interview with Ubisoft Massive's creative director Magnus Jansén regarding the decision to forgo splitscreen co-op.

  • Smartphones May Soon Provide Earthquake Warnings
    2016-02-12T23:14:00+00:00
    sciencehabit writes: When it comes to an earthquake, just a few seconds' warning could make the difference between life and death. But many earthquake-prone countries lack the seismic networks that would give their citizens the lead time to find cover or shut down critical utilities. Now, a group of enterprising engineers is looking at a substitute network: smartphones. Using smartphones' built-in accelerometers, researchers have invented an app, released today, that they say can detect strong earthquakes seconds before the damaging seismic waves arrive. MyShake, as the app is called, could become the basis for an earthquake warning system for the world's most vulnerable regions.

  • Researchers Improve Efficiency of Plug-in Hybrid Electric Vehicles By Almost 12%
    2016-02-12T22:46:00+00:00
    hypnosec writes: A new study has put forward claims that by working on and improving the energy management system (EMS) that decides when the switch from 'all-electric' mode to 'hybrid' mode in plug-in hybrid electric vehicles, efficiency of these vehicles can be improved by as much as 12 per cent. Researchers have shown in their lab tests that blended discharge strategies wherein power from the battery is used throughout the trip, have proven to be more efficient at minimizing fuel consumption and emissions.

  • US Copyright Law Forces Wikimedia To Remove the Diary of Anne Frank
    2016-02-12T22:23:00+00:00
    Today, the Wikimedia Foundation announced its removal of The Diary of Anne Frank from Wikisource, a digital library of free texts. According to the United States' Digital Millennium Copyright Act, works are protected for 95 years from the date of publication, meaning Wikimedia is not allowed to host a copy of the book before 2042. Rogers, the Legal Counsel for the Wikimedia Foundation, says this is just one of the many examples of the overreach of the United States' current copyright law. He goes on to say, "Our removal serves as an excellent example of why the law should be changed to prevent repeated extensions of copyright terms."

  • French Court Rules That Facebook Can Now Be Sued in France
    2016-02-12T21:41:00+00:00
    An anonymous reader writes: A Paris court of appeal has ruled in favor of a French complainant whose account was suspended, because he linked to an image of the 1866 Gustav Courbet nude 'L'Origine du monde', currently residing at the Musee d'Orsay. The appeals court not only agreed that the user's suspension by Facebook constitutes censorship, but the ruling itself negates Facebook's insistence that all legal challenges take place in its native California.

  • Ask Slashdot: Do You Still Have a Pager? Do You Find It Useful?
    2016-02-12T20:59:00+00:00
    New submitter Chance Callahan writes: I am starting a business, helping a friend with his own startup, and volunteering regularly with a major political campaign (#feelthebern). One thing I have noticed is that my phone likes to die at the most inconvenient times and leaves me out of touch with people. With the business I'm starting requiring clients to be able to get ahold me quickly, I have been seriously considering getting a two-way pager. It's much easier swap out a AA battery once a month then to worry "will client X be able to get ahold me in the event of an emergency?" So, Slashdot, the million dollar question is, in the age of cell phones, do you have a pager? Do you still find it useful? Do any other "dead-tech" tools still play a big role for your communications? For example, fax machines are still big in Japan, and a lot of people keep landlines, too.
