  • Pixman 0.38 Released With Meson Build System Support

    Pixman 0.38 is out this morning to kick off a new week of open-source software releases. Pixman is the pixel manipulation library used by the X.Org Server, Cairo, and other Linux software projects.

    The Pixman 0.38 release isn't the most exciting update and in fact only a handful of changes over Pixman 0.36 from last November, which itself was the first update to this library in three years. Pixman doesn't see too much activity these days thanks in part to more software using Vulkan and OpenGL to benefit from GPU hardware acceleration. The two primary changes of Pixman 0.38.0 is introducing Meson build system support and implementing floating point gradient computation.

  • Vulkan 1.1.100 Released Ahead Of Vulkan's Third Birthday

    Vulkan 1.1.100 was published this morning as the latest version of this high-performance, multi-platform graphics and compute API.

    While the patch version rolled over to 100, that's about as exciting as this update gets to Vulkan API with no major changes to mark this milestone. There aren't any great new extensions or major changes to this version number, but just some documentation/specification clarifications and corrections.

  • Sway 1.0 Close To Release For This Very Promising Wayland Compositor

    Out today is the second release candidate of the feature-packed Sway 1.0 Wayland compositor that continues to be inspired by the i3 window manager.

    Since last week's Sway 1.0 RC1, the compositor entered its feature freeze until the stable release happens. As such, in today's Sway 1.0 RC2 update is just a variety of bug/regression fixes.

    The Sway 1.0 development over the past number of months has brought a lot of improvements and new features from multi-GPU support, support for new Wayland protocols, video capture support, integration around the WLROOTS library, tablet support, and many other additions.

  • NVIDIA's VDPAU Picks Up HEVC 4:4:4 Support

    While NVIDIA is no longer active promoting their Video Decode and Presentation API for Unix "VDPAU" in favor of the cross-platform, CUDA-focused Video Codec SDK with NVENC/NVDEC, the VDPAU library still sees some rare activity from time to time.

    As the first commits since November, last week libvdpau added support for the HEVC 4:4:4 profile to the VDPAU API. This support for H.265 4:4:4 video decoding was added to the libvdpau API and presumably will be exposed by the NVIDIA proprietary driver shortly if it's not already in place with its own VDPAU library build.

ExTiX 19.4 "The Ultimate Linux System" is Based on Deepin 15.9.3 and Linux 5.0

The biggest news about the ExTiX Deepin 19.4 release is that it's the first GNU/Linux distribution to be based on the upcoming Deepin Linux 15.9.3 release, which is currently in beta stages of development and has not yet been officially released by Deepin Technology. Additionally, ExTiX Deepin 19.4 comes with the Linux 5.0.8 kernel for the best possible hardware support, making ExTiX worthy for its "The Ultimate Linux System" nickname. Latest Refracta Snapshot is included as well by default for those who want to make their own ExTiX Deepin 19.4 live systems, along with Spotify and Skype apps. Read more

FreeBSD ZFS vs. ZoL Performance, Ubuntu ZFS On Linux Reference

With iX Systems having released new images of FreeBSD reworked with their ZFS On Linux code that is in development to ultimately replace their existing FreeBSD ZFS support derived from the code originally found in the Illumos source tree, here are some fresh benchmarks looking at the FreeBSD 12 performance of ZFS vs. ZoL vs. UFS and compared to Ubuntu Linux on the same system with EXT4 and ZFS. Using an Intel Xeon E3-1275 v6 with ASUS P10S-M WS motherboard, 2 x 8GB DDR4-2400 ECC UDIMMs, and Samsung 970 EVO Plus 500GB NVMe solid-state drive was used for all of this round of testing. Just a single modern NVMe SSD was used for this round of ZFS testing while as the FreeBSD ZoL code matures I'll test on multiple systems using a more diverse range of storage devices. Read more

Why Linux stands out amongst other OSes

Up until recently, Elementary OS was my platform of choice. It's an elegant, simple, and user-friendly solution for the desktop. One thing that the Elementary developers do that I believe is fairly wise is to not allow upgrades from one major release to another. In other words, if you use Elementary OS Loki, you can't upgrade to Juno. To get the benefits of Juno, you must do a full-blown re-install of the OS. Why is this route wise? My latest adventures in Linux will help explain. A few months ago, I purchased a System76 Thelio. It's a beast of a desktop, while at the same a masterful work of art. Preinstalled on that desktop machine was System76's own Pop!_OS. Based on Ubuntu, it seemed like a great way for me to dive back into the GNOME desktop. So I did. It took no time to get accustomed to the new workflow with GNOME. Once my fingers understood the new keyboard shortcuts, I was good to go. Read more
