  • Linux 4.14.10 and 4.9.73 LTS Kernels Are Available to Download, Update Now

    Renowned Linux kernel maintainer and developer Greg Kroah-Hartman announced a couple of days the release and immediate availability of the Linux 4.14.10 and 4.9.73 LTS kernels.

    While Linux kernel 4.9.73 LTS is a small patch that changes a total of 22 files with 191 insertions and 56 deletions, the Linux 4.14.10 kernel is a major one, changing no less than 116 files, with 4023 insertions and 3424 deletions. According to the appended shortlog, most of the changes included in Linux kernel 4.14.10 are related to merging of the x86 low-level prep for kernel page table isolation.

  • KVM Smokes VirtualBox On Initial AMD EPYC Linux Tests

    I've been working on some AMD EPYC virtualization tests on and off the past few weeks. For your viewing before ending out the year are some initial VirtualBox vs. Linux KVM benchmarks for seeing how the guest VM performance compares.

  • Resources for learning bash/shell scripting in GNU/Linux

    There is a stigma around the word Linux, where people generally envision people with glasses, beards, and look like a hippy programmer. Funny enough, this perfectly describes Richard Stallman, the creator of GNU, the actual operating system that we simply refer to as ‘Linux’ nowadays (much to his distaste.)

    However, part of this stigma, is also that GNU/Linux users are constantly glued to terminals, hacking away code constantly to run their operating system. This once upon a time wasn’t too far off, but nowadays most users may never even see the terminal.

    However, those who do wish to dive in deeper, and really see the true power behind using a CLI, may wish to learn shell programming / scripting. The applications of doing so, are virtually boundless; from automating to maintenance.

  • KDE Goal: Usability and Productivity

    It’s been an honor to have had the community select my KDE goal: focus on usability and productivity. This is a topic that’s quite dear to my heart, as I’ve always seen a computer for a vehicle for giving substance to your thoughts. Low-quality computer operating systems and software get in your way and knock you out of a state of flow, while high quality versions let you create at the speed of thought. KDE Plasma is already pretty good in this department, but I think we can make it even better–we can turn it into the obvious choice for people who need to get things done.

  • [Stable Update] 2017-12-31 – Kernels, Xorg-Server, Mesa, Compiz, Wine, Firefox

    this is our second try with Xorg-Server v1.19.6. This time we also updated our Mesa-Stack and changed the handling of dri/drm. Some reported Compiz not working with this. Therefore we had it updated to the latest source currently available.

    Friends of Gimp may try out the latest development edition of this fantastic graphical art app. Again we have the latest Firefox and Wine added. Also linux49 and linux414 got updated to their latest point-releases.

  • Source code for Apple's 1983 Lisa computer to be made public next year

    The museum's software curator, Al Kossow, announced to a public mailing list that the source code for the Lisa computer has been recovered and is with Apple for review.

Graphics: XRGEARS and Arcan's Latest

  • XRGEARS: Infamous "Gears" Now On VR Headsets With OpenHMD, Vulkan
    Well, the virtual reality (VR) demo scene is now complete with having glxgears-inspired gears and Utah teapot rendering on VR head mounted displays with the new XRGEARS. Kidding aside about the gears and teapot, XRGEARS is a nifty new open-source project with real value by Collabora developer Lubosz Sarnecki. XRGEARS is a standalone VR demo application built using the OpenHMD initiative for tracking and Vulkan for rendering. XRGEARS supports both Wayland and X11 environments or even running off KMS itself. This code also makes use of VK_EXT_direct_mode_display with DRM leasing.
  • Arcan versus Xorg – Approaching Feature Parity
    This is the first article out of three in a series where I will go through what I consider to be the relevant Xorg feature set, and compare it, point by point, to how the corresponding solution or category works in Arcan. This article will solely focus on the Display Server set of features and how they relate to Xorg features, The second article will cover the features that are currently missing (e.g. network transparency) when they have been accounted for. The third article will cover the features that are already present in Arcan (and there are quite a few of those) but does not exist in Xorg.
  • Arcan Display Server Is Nearing Feature Parity With The X.Org Server
    The Arcan display server, which started off years ago sounding like a novelty with being a display server built off a game engine in part and other interesting features, is nearing feature parity with the X.Org Server. While most hobbyist display server projects have failed, Arcan has continued advancing and with an interesting feature set. Recently they have even been working on a virtual reality desktop and an interesting desktop in general. Arcan is getting close to being able to offering the same functionality as a traditional X.Org Server. If you are interested in a lengthy technical read about the differences between Arcan and X.Org, the Arcan developers themselves did some comparing and contrasting when it comes to the display support, windowing, input, font management, synchronization, and other areas.

CoC/Systemd Supremacy Over Linux Kernel

  • New Linux Code of Conduct Revisions: CoC Committee Added Plus Interpretation & Mediator
    The Linux Code of Conduct introduced last month that ended up being quite contentious will see some revisions just ahead of the Linux 4.19 stable kernel release. Greg Kroah-Hartman has outlined the planned changes as well as a new Code of Conduct Interpretation document. In the weeks since the Linux kernel CoC was merged, various patches were proposed but none merged yet. It turns out Greg KH was working in private with various kernel maintainers/developers on addressing their feedback and trying to come up with solutions to the contentious issues in private.
  • Some kernel code-of-conduct refinements
    Greg Kroah-Hartman has posted a series of patches making some changes around the newly adopted code of conduct. In particular, it adds a new document describing how the code is to be interpreted in the kernel community.
  • Systemd Adds Feature To Fallback Automatically To Older Kernels On Failure
    Systemd's latest feature is the concept of "boot counting" that will track kernel boot attempts and failures as part of an automatic boot assessment. Ultimately this is to provide automatic fallback to older kernels should a newer kernel be consistently failing. The feature was crafted over the past few months by Lennart Poettering himself to provide a way when making use of systemd-boot on UEFI systems it can automatically fallback to an older kernel if a newer kernel is consistently causing problems. This is treated as an add-on to the Boot Loader Specification. The systemd boot assessment is designed that it could also be used by non-UEFI systems and other boot platforms.

ODROID 'Hacker Board'

  • ODROID Rolling Out New Intel-Powered Single Board Computer After Trying With Ryzen
    While ODROID is most known for their various ARM single board computers (SBCs), some of which offer impressive specs, they have dabbled in x86 SBCs and on Friday announced the Intel-powered ODROID-H2. In the announcement they mentioned as well they were exploring an AMD Ryzen 5 2500U powered SBC computer, which offered fast performance but the price ended up being prohibitive. After the falling out with Ryzen over those cost concerns, they decided to go ahead with an Intel Geminilake SoC. Geminilake is slower than their proposed Ryzen board, but the price was reasonable and it ends up still being much faster than ODROID's earlier Apollolake SBC.
  • Odroid-H2 is world’s first Gemini Lake hacker board
    Hardkernel unveiled the Odroid-H2, the first hacker board with an Intel Gemini Lake SoC. The Ubuntu 18.10 driven SBC ships with 2x SATA 3.0, 2x GbE, HDMI and DP, 4x USB, and an M.2 slot for NVMe. When the Odroid-H2 goes on sale in November at a price that will be “higher than $100,” Hardkernel will join a small group of vendors that have launched a community backed x86-based SBC. This first open spec hacker board built around Intel’s new Gemini Lake SoC — and one of the first Gemini Lake SBCs of any kind — follows earlier Arm-based Odroid winners such as the Odroid-C2 Raspberry Pi pseudo clone and the octa-core Odroid-XU4.
