  • Fedora Looks To Build Firefox With Clang For Better Performance & Compilation Speed
    Following the move by upstream Mozilla in switching their Linux builds of Firefox from being compiled by GCC to LLVM Clang, Fedora is planning the same transition of compilers in the name of compilation speed and resulting performance. FESCo Ticket 2020 laid out the case, "Mozilla upstream switches from gcc to clang and we're going to follow upstream here due to clang performance, maintenance costs and compilation speed. Tom Stellard (clang maintainer) has asked me to file this ticket to comply with Fedora processes."

    SolidRun’s “ClearFog CX 8K” SBC is built around a “CEx7 A8040” COM Express Type 7 module that runs Linux on a quad -A72 Armada A8040. Features include 4x 10GbE SFP+ ports and mini-PCIe, M.2, and SATA expansion. In August, SolidRun updated its ClearFog line of Linux-driven router boards with a high-end ClearFog GT 8K SBC with the same 2GHz, quad-core, Cortex-A72 Marvell Armada A8040 SoC found on its MacchiatoBIN Double Shot Mini-ITX board. Now, the company has returned to the headless (no graphics) Armada A8040 with the ClearFog CX 8K. [..] It’s rare to see an Arm-based Type 7 module.
  • Watch Out: Clicking “Check for Updates” Still Installs Unstable Updates on Windows 10
    Microsoft hasn’t learned its lesson. If you click the “Check for Updates” button in the Settings app, Microsoft still considers you a “seeker” and will give you “preview” updates that haven’t gone through the normal testing process. This problem came to everyone’s attention with the release of the October 2018 Update. It was pulled for deleting people’s files, but anyone who clicked “Check for Updates” in the first few days effectively signed up as a tester and got the buggy update. The “Check for Updates” button apparently means “Please install potentially updates that haven’t gone through a normal testing process.”

  • Will Concerns Break Open Source Containers?
    Open source containers, which isolate applications from the host system, appear to be gaining traction with IT professionals in the U.S. defense community. But for all their benefits, security remains a notable Achilles’ heel for a couple of reasons. First, containers are still fairly nascent, and many administrators are not yet completely familiar with their capabilities. It’s difficult to secure something you don’t completely understand. Second, containers are designed in a way that hampers visibility. This lack of visibility can make securing containers extremely taxing.

  • How Shared, Open Data Can Help Us Better Overcome Disasters
    WHEN A MASSIVE earthquake and tsunami hit the eastern coast of Japan on March 11, 2011, the Fukushima Daiichi Nuclear Power Plant failed, leaking radioactive material into the atmosphere and water. People around the country as well as others with family and friends in Japan were, understandably, concerned about radiation levels—but there was no easy way for them to get that information. I was part of a small group of volunteers who came together to start a nonprofit organization, Safecast, to design, build, and deploy Geiger counters and a website that would eventually make more than 100 million measurements of radiation levels available to the public. We started in Japan, of course, but eventually people around the world joined the movement, creating an open global data set. The key to success was the mobile, easy to operate, high-quality but lower-cost kit that the Safecast team developed, which people could buy and build to collect data that they might then share on the Safecast website.

  • Someone messed with Linux.org's DNS to deface the website's homepage [Ed: That's not "deface"' but more like redirect and it's not the site's DNS system but something upstream, another company that's at fault]
    SO IMAGINE YOU REALLY LOVE OPEN SOURCE; you've poured yourself a glass of claret from a wine box and have settled into a night of perusing Linux.org. You feel a tingle of excitement as you type in the URL - you're old skool - but that sours to despair as you see a defaced website greet your eyes. Yep, it looks like someone managed to get into the Linux.org website's domain name service (DNS) settings and point the domain to another server that served up a defaced webpage, which depending on when you may have accessed it, greeted visitors with racial slurs, an obscene picture and a protest against the revised Linux kernel developer code of conduct.
