  • GitHub Is Undergoing a Full-Blown Overhaul As Execs and Employees Depart
    2016-02-06T18:23:00+00:00
    mattydread23 writes: This is what happens when hot startups grow up. [GitHub] CEO Chris Wanstrath is imposing management structure where there wasn't much before, and execs are departing, partly because the company is cracking down on remote work. It's a lot like Facebook in 2009. Business Insider has the full inside story based on multiple sources in and close to the company.

  • Giant Magellan Telescope Set To Revolutionize Ground-Based Astronomy
    2016-02-06T17:24:00+00:00
    StartsWithABang writes: If you want to see farther, deeper and at higher resolution than ever before into the Universe, you need four things: the largest aperture possible, the best-quality optical systems and cameras/CCDs, the least interference from the atmosphere, and the analytical techniques and power to make the most of every photon. While the last three have improved tremendously over the past 25 years, telescope size hasn't increased at all. That's all about to change over the next decade, as three telescopes — the Giant Magellan Telescope, the Thirty Meter Telescope and the European Extremely Large Telescope — are set to take us from 8-10 meter class astronomy to 25-40 meter class. While the latter two are fighting over funding, construction rights and other political concerns, the Giant Magellan Telescope is already under construction, and is poised to be the first in line to begin the future of ground-based astronomy.

  • Even With Telemetry Disabled, Windows 10 Talks To Dozens of Microsoft Servers
    2016-02-06T16:28:00+00:00
    An esteemed reader writes: Curious about the various telemetry and personal information being collected by Windows 10, one user installed Windows 10 Enterprise and disabled all of the telemetry and reporting options. Then he configured his router to log all the connections that happened anyway. Even after opting out wherever possible, his firewall captured Windows making around 4,000 connection attempts to 93 different IP addresses during an 8 hour period, with most of those IPs controlled by Microsoft. Even the enterprise version of Windows 10 is checking in with Redmond when you tell it not to — and it's doing so frequently.

  • Let Your Pupils Do the Typing
    2016-02-06T15:29:00+00:00
    New submitter s.mathot writes: Researchers from France and the Netherlands have developed a way to—literally—write text by thinking of letters. (Academic paper [open access], non-technical blog, YouTube video.) This technique relies on small changes in pupil size that occur when you covertly (from the corner of your eye; without moving your eyes or body) attend to bright or dark objects. By presenting a virtual keyboard on which the 'keys' alternate in brightness, and simultaneously measuring the size of the eye's pupil, the technique automatically determines which letter you want to write; as a result, you can write letters by merely attending to them, without moving any part of your body, including the eyes.

  • Twitter Tackles Terrorists In Targeted Takedown
    2016-02-06T14:27:00+00:00
    Mark Wilson writes: Having previously battled trolls, Twitter has now turned its attention to terrorists and their supporters. The site has closed down more than 125,000 accounts associated with terrorism since the middle of 2015, it announced in a statement. Although a full breakdown of figures is not provided, Twitter says most of these accounts were related to ISIS. Having increased the size of its account review team, the site has reduced the time it takes to investigate accounts that are reported, and has also started to investigate 'accounts similar to those reported'.

  • Verizon's Mobile Video Won't Count Against Data Caps -- but Netflix Will
    2016-02-06T13:33:00+00:00
    Earthquake Retrofit writes: Ars Technica has a story about how Verizon Wireless is testing the limits of the Federal Communications Commission's net neutrality rules; Verizon has announced that it will exempt its own video service from mobile data caps—while counting data from competitors such as YouTube and Netflix against customers' caps.

  • Online Museum Displays Decades of Malware
    2016-02-06T11:19:00+00:00
    An anonymous reader writes: archive.org has launched a Museum of Malware, which devotes itself to a historical look at DOS-based viruses of the 1980s and 1990s, and gives viewers the opportunity to run the viruses in a DOS game emulator, and to download 'neutered' versions of the code. With an estimated 50,000 DOS-based viruses in existence by the year 2000, the Malware Museum's 65 examples should be seen as representative of an annoying, but more innocent era of digital vandalism.

  • Docker Images To Be Based On Alpine Linux
    2016-02-06T08:28:00+00:00
    New submitter Tenebrousedge writes: Docker container sizes continue a race to the bottom with a couple of environments weighing in at less than 10MB. Following on the heels of this week's story regarding small images based on Alpine Linux, it appears that the official Docker images will be moving from Debian/Ubuntu to Alpine Linux in the near future. How low will they go?

  • Avast SafeZone Browser Lets Attackers Access Your Filesystem
    2016-02-06T05:39:00+00:00
    An anonymous reader writes: Just two days after Comodo's Chromodo browser was publicly shamed by Google Project Zero security researcher Tavis Ormandy, it's now Avast's turn to be publicly scorned for failing to provide a "secure" browser for its users. Called SafeZone, and also known as Avastium, Avast's custom browser is offered as a bundled download for all who purchase or upgrade to a paid version of Avast Antivirus 2016. This poor excuse of a browser was allowing attackers to access files on the user's filesystem just by clicking on malicious links. The browser wouldn't even have to be opened, and the malicious link could be clicked in "any" browser.

    An anonymous reader writes: On Tuesday, a new simple solution for streaming torrents directly in your browser showed up on the Web. By Friday, infamous torrent site The Pirate Bay had already adopted it. The Pirate Bay now features "Stream It!" links next to all its video torrents. As a result, you can play movies, TV shows, and any other video content directly in the same window you use to browse the torrent site.

    MarkWhittington writes: According to a story in the Palm Beach Post, Edgar Mitchell, the sixth man to walk on the moon, has died at the age of 85. He flew as lunar module pilot on board Apollo 14, which flew to and from the moon between January 31, 1971 and February 9, 1971. His crewmates were Alan Shepard and Stuart Roosa. Apollo 14 was the return to flight for the moon landing program after the near disaster of Apollo 13 in April 1970, and explored the Fra Mauro highlands on the lunar surface. NASA marks Mitchell's passing as well.

  • Nintendo Hits Snooze On Sleep-Tracking Device
    2016-02-05T23:30:00+00:00
    In October 2014, Nintendo announced a plan to develop a sleep-tracking app and device. This device would use microwave sensors to monitor important sleep data throughout the night, to optimize users' slumber time and encourage a healthier rest cycle. Now, Nintendo has announced that the sleep app has been put to sleep indefinitely; the company is instead focusing on its new mobile games and next-generation console.

  • Some Reversible USB-C Cables/Adapters Could Cause Irreversible Damage
    2016-02-05T22:47:00+00:00
    TheRealHocusLocus writes: Three Decembers ago I lauded the impending death of the trapezoid. Celebration of the rectangle might be premature however, because in the rush-to-market an appalling number of chargers, cables and legacy adapters have been discovered to be non-compliant. There have been performance issues with bad USB implementation all along, but now — with improved conductors USB-C offers to negotiate up to 3A in addition the 900ma base, so use of a non-compliant adapter may result in damage. Google engineer and hero Benson Leung has been waging a one-man compliance campaign of Amazon reviews to warn of dodgy devices and praise the good. Reddit user bmcclure937 offers a spreadsheet summary of the reviews. It's a jungle out there, don't get fried.

  • Scareware Signed With Apple Cert Targets OS X Machines
    2016-02-05T22:06:00+00:00
    msm1267 writes: A unique scareware campaign targeting Mac OS X machines has been discovered, and it's likely the developer behind the malware has been at it a while since the installer that drops the scareware is signed with a legitimate Apple developer certificate. "Sadly, this particular developer certificate (assigned to a Maksim Noskov) has been used for probably two years in similar attacks," said Johannes Ullrich, dean of research of the SANS Institute's Internet Storm Center, which on Thursday publicly disclosed the campaign. "So far, it apparently hasn't been revoked by Apple."

  • Foxconn Set To Acquire Sharp Corporation For $5.6 Billion
    2016-02-05T21:46:00+00:00
    Foxconn, a Taiwanese electronics contract manufacturing/assembly company, is reported to be finalizing a deal to acquire Sharp Corporation for $5.6 billion, with the beleaguered company having finally rejected a proposed government rescue package in favor of the deal. Foxconn, formerly known as Hon Hai Precision Industry Co. Ltd, was brought to media attention in 2010, when the company installed suicide nets to stop the high number of employee suicides at company dorms. Although it seems out of the ordinary that one of the world's few producers of LCD panels is negotiating with Foxconn, the deal is expected to go through, making it one of the biggest foreign takeovers of a Japanese company.
