  • Porting guide from Qt 1.0 to 5.11

    We do try to keep breakages to a minimum, even in the major releases, but the changes do add up. This raises the question: How hard would it be to port a Qt application from Qt 1.0 to 5.11?

  • Thunderbolt Networking on Linux

    Thunderbolt allows for peer-to-peer network connections by connecting two computers directly via a thunderbolt cable. Mika from Intel added support for this to the 4.15 kernel. Recently, Thomas Haller from NetworkManager and I worked together to figure out what needs to be done in userspace to make it work. As it turns out, it was not that hard and the pull-request was merged swiftly.

  • What’s new in openSUSE Leap 15 – part 1

    openSUSE Leap 15 will be released on the 25th of May 2018! A new openSUSE release is always an exciting event. This means that I get to play with all kinds of new and improved software packages.

    I am aware that I can simply install openSUSE Tumbleweed and have a new release 4 or 5 times a week. But when using openSUSE Tumbleweed some time ago, I noticed that I was installing Gigabytes of new software packages multiple times per week. The reason for that is that I have the complete opposite of a minimum install. I always install a lot of applications to play / experiment with (including a lot of open source games). I am using openSUSE since 2009 and it covers all of my needs and then some. I am already happy with the available software, so there is no real reason for me to move with the speed of a rolling release. Therefore I prefer to move with the slower pace of the Leap releases.

  • UBports To Work On Unity 8 / Mir / Wayland After OTA-4

    The UBports team have put out their latest batch of answers to common questions around this project that's still working to maintain the Ubuntu Touch software stack.

    Among the project's recent work has included getting QtWebEngine working on Mir and before their Ubuntu 16.04 LTS based release they still need to figure out Chromium crashes and to resolve that as well as updating the browser. For their first release of UBports derived from Ubuntu 16.04 "Xenial" they are still going to rely upon Oxide while later on should migrate to a new browser.

  • What's Coming in OpenStack Rocky?

    The OpenStack Rocky release is currently scheduled to become generally available on August 30th, and it's expected to add a host of new and enhanced capabilities to the open-source cloud platform.

    At the OpenStack Summit here, Anne Bertucio, marketing manager at the OpenStack Foundation, and Pete Chadwick, director of product management at SUSE, outlined some of the features currently on the Rocky roadmap.

    Bertucio began the session by warning the audience that the roadmap is not prescriptive, but rather is intended to provide a general idea of the direction the next OpenStack release is taking.

  • PostgreSQL 11 Is Continuing With More Performance Improvements, JIT'ing

    PostgreSQL 11 is the next major feature release of this open-source database SQL server due out later in 2018. While it's not out yet, their release notes were recently updated for providing an overview of what's coming as part of this next major update.

    To little surprise, performance improvements remain a big focus for PostgreSQL 11 with various optimizations as well as continued parallelization work and also the recently introduced just-in-time (JIT) compilation support.

  • Tesla disclosed some of its autopilot source code after GPL violation

    Tesla, a technology company, and the independent automaker are well known for offering the safest, quickest electric cars. The company uses a lot of open source software to build its operating system and features, such as Linux Kernel, Buildroot, Busybox, QT, etc also they have always been taciturn about the finer details and tech of its popular artefacts, such as Model S, Model X, but now Elon Musk’s company has just released some of its automotive tech source code into the open source community.

A Look At The Windows vs. Linux Scaling Performance Up To 64 Threads With The AMD 2990WX

This past week we looked at the Windows 10 vs. Linux performance for AMD's just-launched Ryzen Threadripper 2990WX and given the interest from that then ran some Windows Server benchmarks to see if the performance of this 64-thread CPU would be more competitive to Linux. From those Windows vs. Linux tests there has been much speculation that the performance disparity is due to Windows scheduler being less optimized for high core/thread count processors and its NUMA awareness being less vetted than the Linux kernel. For getting a better idea, here are benchmarks of Windows Server 2019 preview versus Ubuntu Linux when testing varying thread/core counts for the AMD Threadripper 2990WX. Toggled via the BIOS was SMT as well as various CCX configurations and each step of the way comparing the Windows Server 2019 Build 17733 performance to that of Ubuntu 18.04 LTS with the Linux 4.18 kernel in various multi-threaded benchmarks supported under both operating systems.

Kernel: RISC-V and Virtual Machine

  • RISC-V's Linux Kernel Support Is Getting Into Good Shape, Userspace Starting To Work
    The RISC-V open-source processor ISA support within the mainline kernel is getting into good shape, just a few releases after this new architecture port was originally added to the Linux Git tree. The RISC-V code for Linux 4.19 includes the ISA-mandated timers and first-level interrupt controllers, which are needed to actually get user-space up and running. Besides the RISC-V first-level interrupt controller, Linux 4.19 also adds support for SiFive's platform-level interrupt controller that interfaces with the actual devices.
  • A Hearty Batch Of KVM Updates Land In Linux 4.19
    There is a lot of new feature work for the Kernel-based Virtual Machine (KVM) within the Linux 4.19 kernel.

Kate/KTextEditor Picks Up Many Improvements To Enhance KDE Text Editing

Even with KDE's annual Akademy conference happening this past week in Vienna, KDE development has been going strong especially on the usability front. The Kate text editor and the KTextEditor component within KDE Frameworks 5 have been the largest benefactors of recent improvements. This KDE text editing code now has support for disabling syntax highlighting entirely if preferred. When using syntax highlighting, there have been many KTextEditor enhancements to improve the experience as well as improvements to the highlighting for a variety of languages from JavaScript to YAML to AppArmor files.
