SWVKC Is A Vulkan-Powered Wayland Compositor Focused On Performance + Correctness

Sunday 26th of July 2020 04:49:08 PM
While the current Vulkan API is exhaustive enough to implement full-featured Wayland compositors and X11 window managers, to date there hasn't been too much adoption considering OpenGL is still more pervasive among hardware/drivers and it's obviously a significant effort writing a new compositor from scratch. One of the leading (among few) examples of a Vulkan-powered window manager / compositor is ChamferWM, which does continue to be developed. SWVKC meanwhile is one that has been seeing development this year as an alpha-stage Wayland Vulkan compositor...

Linux Foundation Broadens Relationship With Surveillance

  • Facebook joins The Linux Foundation as a platinum member

    Most web-based companies are built on Linux and open-source software. Two-billion member social network Facebook is no different. For years, Facebook has not only relied on open-source, it's been an active contributor to major open-source projects. These include the React JavaScript library; the Open Compute Project, which open sources data-center hardware; and Linux's cGroup2 container software. Now Facebook is joining The Linux Foundation membership at the Platinum level. [...] While Facebook has been criticized for how it deals with privacy and politics, it has impeccable open-source credentials. It was already the lead contributor of many Linux Foundation-hosted projects, such as Presto, GraphQL, Osquery, and ONNX. The company also employs many Linux kernel key developers and maintainers.

Graphics: Mesa 20.2 RC2 and DXVK 1.7.1

  • mesa 20.2.0-rc2
    Hi list,
    Available today is mesa 20.2.0-rc2. This is the second release candidate for
    the 20.2 release. Currently our open to close ratio on blocking bugs is looking
    really good. This release is dominated by changes to radeonsi, radv, and aco,
    with a few additional changes sneaking in for freedreno, meson,  etnaviv,
    st/mesa, anv, and a few utility fixes.
  • Mesa 20.2-RC2 Released With Many Fixes For RadeonSI + RADV Drivers

    The second weekly release candidate of the forthcoming Mesa 20.2 is now available for testing. Mesa 20.2 is aiming for release around the end of August or early September depending upon how the bug situation plays out. This quarterly feature release to Mesa3D brings many new Vulkan extensions, the RADV driver using ACO by default, initial support for Navi 2 GPUs, initial support for Intel Rocket Lake and DG1, OpenGL 4.3 for LLVMpipe, and much more as outlined in last week's article.

  • DXVK 1.7.1 Released With Many Game Fixes For Direct3D Over Vulkan

    It's been nearly three months without a new DXVK release for mapping Direct3D 9/10/11 atop the Vulkan API while finally today there is a big feature release out. DXVK 1.7.1 was released a few minutes ago as the first update since May. While the version number isn't significant, this version does have many changes.

  • Direct3D to Vulkan translation layer DXVK 1.7.1 is out, lots of game fixes

    After a few months since 1.7 went out, DXVK 1.7.1 is now live to further improve Direct3D to Vulkan translation. This is the project that helps to power Proton, the compatibility layer for Steam Play. This release adds support for newer Vulkan extensions, fixes bugs and has new GPU driver requirements. On the driver side, the VK_EXT_transform_feedback extension is now required which has been supported in drivers on Linux since late 2018 / early 2019. Specifically you will need at least NVIDIA 415.22 and for AMD / Intel it looks like Mesa 19 covers both.

Devices/Embedded: Raspberry Pi and Android Devices

  • Indoor air quality HAT for Raspberry Pi boasts high-res TVOC sensor

    Avnet’s $49.95 “Renesas ZMOD4410 Indoor Air Quality HAT for Raspberry Pi” can be used to measure volatile organic compounds, humidity, and temperature, as well as estimate carbon dioxide levels. Avnet has launched a Renesas ZMOD4410 Indoor Air Quality HAT for Raspberry Pi (AES-RHSEN-ZM44-G) that joins other indoor air quality measurement add-ons for the Pi including Metriful’s $44.50 Sense module and Pimoroni’s $57 Enviro+ pHAT. The ZMOD4410 HAT lacks some of the extras of those boards, but appears to offer a higher quality total volatile organic compound (TVOC) sensor with its Renesas ZMOD4410, which offers resolution ranging from parts-per-billion to parts-per-million.

  • Learn Any Programming Language with This Learning Plan

    All it takes to master any programming language is the right learning plan. If you know anything about programming you should be aware that often you can’t tell whether what you are doing is wrong until it’s too late. That’s what makes programming a frustrating skill to master — long hours doing the wrong things. But hey, whether you want to make programming your full-time job or just a hobby, you can always make the learning curve less steep. The secret to getting it right with coding is this: have a learning plan! While the plan will not do the hard lifting for you, it will definitely provide the much-needed elbow grease to keep you grounded and focused as you learn programming.

  • Matt Layman: Rendering Calendars - Building SaaS #68

    In this episode, I worked on rendering a calendar of important events in a school year. We built out the appropriate data structures, and I wrote some new model methods and added tests. On the last stream, I created a new model to track breaks in the school year. The app now shows the calendar for the school year, and I want to display the breaks on the calendar. Before digging too far into the code, I provided my thoughts about using Docker for development from a question that came from the chat.
