  • How I put Linux in the enterprise

    I used to work in higher ed. In the late 1990s, we moved to a new student records system. We created an “add-on” web registration system, so students could register on-line—still a new idea in 1998. But when we finally went live, the load crushed the web servers. No one could register. We tried to fix it, but nothing worked.

    • Linux 4.12.2

      I’m announcing the release of the 4.12.2 kernel.

      All users of the 4.12 kernel series must upgrade.

      The updated 4.12.y git tree can be found at:
      git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.12.y
      and can be browsed at the normal kernel.org git web browser:

    • Linux 4.11.11
    • Linux 4.9.38
    • Linux 4.4.77
    • Linux 3.18.61
    • UBIFS Gets Statx Support, Better Encryption In Linux 4.13

      The Linux 4.13 kernel changes for the UBIFS file-system have been submitted.

      UBIFS, as a reminder, is the Unsorted Block Image File-System deigned for flash memory devices off the UBI layer. UBIFS in Linux 4.10 gained file-encryption support making use of the fscrypt functionality used as well by F2FS and EXT4. With Linux 4.13, there are UBIFS related encryption updates and fixes.

    • Linux 4.13 Thermal Management Sees Some Improvements For CPU_Cooling

      The thermal management updates have landed in the Linux 4.13 code-base.

    • Linux 4.13-rc1 Kernel Released
    • Merge window over – Linux 4.13-rc1 out

      Ok, normally I do this on Sunday afternoon, but occasionally it
      happens a day early like now to avoid people timing me.

      In fact, I was planning on doing it yesterday evening this time around
      because I was so annoyed with lots of late pull requests on Friday
      (and some today), but ended up going to dinner and not getting
      everything done, so it’s only one day early. Next time…

    • The New Changes & Features Of The Linux 4.13 Kernel

      With Linux 4.13-rc1 having been released, here’s my original look at the new features coming for the Linux 4.13 kernel and the other changes merged over the past two weeks of this new cycle.

    • Please pull NFS client changes for Linux 4.13
    • Graphics Stack

      • Mesa 17.1.5 Brings More Fixes To Open-Source GPU Driver Users

        Andres Gomez of Igalia has announced Mesa 17.1.5 as the newest point release to the current Mesa 3D stable series.

        Mesa 17.1.5 fixes a potential crash in core Mesa, has Vulkan / SPIR-V fixes, the usual notable fixes in the Intel i965 and RadeonSI drivers, and some smaller fixes to Etnaviv, OpenSWR, SVGA, and other parts of this massive user-space 3D graphics stack.

      • [Mesa-announce] [ANNOUNCE] mesa 17.1.5

        In Mesa Core we include a fix to prevent a potential crash.

      • Mesa 17.1.5 Linux Graphics Stack Released, Improves AMD Radeon & Intel Drivers

        After teasing us a couple of days ago with the upcoming availability of the fifth maintenance update to the Mesa 17.1 3D Graphics Stack for GNU/Linux distributions, Mesa developer Andres Gomez is now announcing the final release of Mesa 17.1.5.

        Mesa 17.1.5 comes only two weeks after the Mesa 17.1.4 update that probably many of you are using right now on your Linux distros, and it’s here to add an extra layer of improvements for those using AMD Radeon or Intel graphics cards. First off, Mesa 17.1.5 fixes a potential crash in Mesa Core, adds better support for the GLSL and SPIR-V compilers, and solves a linking problem with standalone Android builds.

      • Vulkan 1.0.54 Lands In Mesa For Intel ANV, Some RADV Extensions

        It’s fabulous to see how promptly the Mesa Vulkan drivers are receiving support for new extensions.

        Vulkan 1.0.54 was released on Thursday. This updated promoted the external memory and semaphores extensions from experimental to stable. They also added new extensions for 16-bit storage, dedicated allocation, storage buffer storage class, variable pointers, new memory requirements query, and external fences for external memory.

      • Difficulties and Success Stories

        This hints to a fundamental issue with our approach of using the Present extension in Xwayland. The extension was written with hardware in mind. It assumes a flip happens directly on a screen. There is no intermediate link like a Wayland compositor and if a flip has happened the old buffer is not on the screen anymore. Why do we still try to leverage the Present extension support in Xwayland then? There are two important features of a Wayland compositor we want to have with Xwayland: A tear-free experience for the user and the ability to output a buffer rendered by a direct rendering client on a hardware plane without any copies in between. Every frame is perfect should also remain valid when using some legacy application and that we want no unnecessary copies is simply a question of performance improvements. This is especially important for many of the more demanding games out there, which won’t be Wayland native in the short term and some of them maybe never. Both features need the the full Present extension support in the Xwayland DDX. Without it a direct rendering application would still use the Present extension but only with its fallback code path of copying the Pixmap’s content. And for a tear-free experience we would at least need to sync these copies to the frame events sent by the Wayland compositor or better directly allow multiple buffers, otherwise we would limit our frame rate. In both cases this means again to increase the Present extension support.

      • It Looks Like Intel Could Begin Pushing Graphics Tech More Seriously

        It’s been a while now since last seeing some major graphics advancements on Intel CPUs. With Skylake/Kabylake we are on “Gen 9″ graphics, Kabylake-Refresh / Coffeelake is still Gen9 graphics, Broadwell was on Gen8, Haswell on Gen7.5, and IvyBridge on Gen 7. But with upcoming launches past Kabylake-Refresh/Coffeelake, it looks like we’ll be stamping out Gen 10, Gen 11, and Gen 12.

      • Codeplay Release “clspv”, an OpenCL Tool for Vulkan Enabled Devices

        In collaboration with Google, Codeplay is proud to announce the release of a new open-source tool allowing the compilation of OpenCL C language kernels to run on the Vulkan API.

      • Best be precise

        KSysGuard — the system monitor — on FreeBSD seems oddly precise.

      • Plasma Wayland and Qt 5.9 and beyond

        As you might know Qt 5.8 created challenging problems for our Wayland session and threw our efforts back quite a bit. In this post I want to discuss the actual problems it created, how we are addressing them and looking into the future.

      • The Regressed State Of KDE Plasma On Wayland, But Things Should Get Better

        KWin maintainer Martin Gräßlin has written a blog post explaining the issues they’ve run into with KDE Plasma on Wayland and how changes to Qt have set them back months in their Wayland session support.

      • Akademy Schedule

        The workshops and lightning talks and BoFs are being planned, too. I’m glad Anu Mittal has mentioned her QML + JS workshop, it’s a great topic for getting started with application development. QML is something I’ve never gotten in to, but should, so I’ve penciled this workshop into my schedule as well.

      • [Krita] GSoC’17-Week #4
      • KF5 Applications Porting

        Next week, KDE developers will release the beta of KDE Applications 17.08. This release will again have more applications and nearly all games ported to Qt5/KF5. While Qt4 is already no longer supported for over a year, KDE has decided to support Qt4/kdelibs4-based applications a bit longer.

        The 17.08 release, however, will be the last to include Qt4/kdelibs4-based applications. This means, 17.12 will only include applications that are based on Qt5/KF5. See this mailing list discussion.

      • Kdenlive 17.04.3 released

        In comparison to previous versions this was the least exciting development cycle, in terms of new features, since all focus has been on the code refactoring which will bring more stability and new features. Don’t miss the next Café to keep track on the progress and share your thoughts if you like.

      • Solus 2017.04.18.0 review – Second time lucky?

        Solus 2017 looks like a nice distro, with some obvious visual caveats and tiny functional quirks. It’s reasonable enough than I’m determined to test it on non-UEFI hardware, where I’ll hopefully have more luck. But on a UEFI platform, it seems hopeless. I don’t know there should be a problem when so many other distros do just fine without any issues. Solus seems to be a special snowflake, and it does not cooperate well with a modern and complex system.

        All in all, I cannot recommend the distro, because the outcome may still be harmful. If a distro cannot install properly, the results can be unpredictable. My testing shows some very favorable things, and Budgie looks quite all right now, but as a package, Solus just doesn’t handle UEFI well. I’ll report back after a third, and hopefully lucky test, but you are warned to carefully proceed until the hardware side has been polished. Double sigh. Maybe another another time.

      • Pale Moon browser new release, better media support

        I have updated my palemoon.SlackBuild and have uploaded fresh Slackware packages for this new Pale Moon 27.4.0. As previously shared with you, I diverge from the official developers’ recommendations about how to compile this browser on Linux. For instance the gcc compiler I used on Slackware 14.2 is gcc-5.3.0 (which is part of this distro release). On -current I failed compiling with the gcc-7.1.0 compiler which is the default there and I had to create a “gcc5” package for gcc-5.4.0 (which was an earlier gcc version in slackware-current). I wrote an article on this very blog about that gcc5 package if you are interested, it can be installed in parallel with Slackware’s own gcc-7. There are some other differences, mainly in the way I optimize my build.
