  • 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    While NVIDIA is no longer active promoting their Video Decode and Presentation API for Unix "VDPAU" in favor of the cross-platform, CUDA-focused Video Codec SDK with NVENC/NVDEC, the VDPAU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.

Variscite unveils two i.MX8 QuadMax modules

Variscite announced Linux-powered “VAR-SOM-MX8” and “SPEAR-MX8” modules with an up to an i.MX8 QuadMax SoC plus up to 8GB LPDDR4 and 64GB eMMC. It also previewed a VAR-SOM-6UL COM. At Embedded World next week in Nuremberg, Germany, Variscite will showcase its Linux and Android driven i.MX8-family computer-on-modules, including new VAR-SOM-MX8 and SPEAR-MX8 modules that feature NXP’s highest-end i.MX8 SoC up to a QuadMax model (see farther below). We have already covered most of the other showcased products, including the 14nm fabricated, quad -A53 i.MX8M Mini based DART-MX8M-Mini. When we covered the DART-MX8M-Mini in September, Variscite didn’t have an image or product page, but both are now available here Read more

Programming: Developer Happiness, Rblpapi 0.3.8 and Python

  • Developer happiness: What you need to know
    A person needs the right tools for the job. There's nothing as frustrating as getting halfway through a car repair, for instance, only to discover you don't have the specialized tool you need to complete the job. The same concept applies to developers: you need the tools to do what you are best at, without disrupting your workflow with compliance and security needs, so you can produce code faster. Over half—51%, to be specific—of developers spend only one to four hours each day programming, according to ActiveState's recent Developer Survey 2018: Open Source Runtime Pains. In other words, the majority of developers spend less than half of their time coding. According to the survey, 50% of developers say security is one of their biggest concerns, but 67% of developers choose not to add a new language when coding because of the difficulties related to corporate policies.
  • Rblpapi 0.3.8: Keeping CRAN happy
    A minimal maintenance release of Rblpapi, now at version 0.3.9, arrived on CRAN earlier today. Rblpapi provides a direct interface between R and the Bloomberg Terminal via the C++ API provided by Bloomberg (but note that a valid Bloomberg license and installation is required). This is the ninth release since the package first appeared on CRAN in 2016. It accomodates a request by CRAN / R Core to cope with staged installs which will be a new feature of R 3.6.0. No other changes were made (besides updating a now-stale URL at Bloomberg in a few spots and other miniscule maintenance). However, a few other changes have been piling up at the GitHub repo so feel free to try that version too.
