We've seen a lot of odd products pick up the Free Software Foundation's "Respect Your Freedom" endorsement like a USB microphone, various re-branded motherboards, and even last year certified a USB to parallel printer cable. The latest product they are endorsing -- and their first endorsement of 2020 -- is a USD 802.11 a/b/g/n PCIe half-mini card starting out at $59 USD but going up to $79 for this outdated wireless adapter...

Among many other Valve ACO back-end improvements for Mesa 20.0, one of the notable additions is this AMDGPU LLVM alternative now working for Radeon "Southern Islands" / GCN 1.0 graphics cards. With this, these original AMD GCN graphics cards may have some extra life out of Linux gaming boxes thanks to slightly higher performance some eight years after these graphics cards first launched in the Radeon HD 7000 series.

While WireGuard was merged into Linux 5.6, the Ubuntu 20.04 LTS release is currently tracking Linux 5.4 and for the April release is likely to be shipping with Linux 5.5 as the 5.6 release will be cutting it too close. But Ubuntu 20.04's kernel has now back-ported WireGuard...

With LLVM Clang 10 having added a Zen 2 scheduler model tuned for the latest AMD CPUs over the existing "znver2" tuning that had just copied the Zen 1 scheduler, here are some benchmarks looking at the LLVM Clang 9 vs. 10 compiler performance on AMD EPYC when making use of "-march=znver2" optimizations...

Since the stable release of Linux 5.5 this weekend I have been carrying out benchmarks for looking at how the performance of this newly-minted kernel compares to older releases. Here are benchmark results of Linux 5.3 vs. 5.4 vs. 5.5 with an AMD Ryzen Threadripper 3970X but the results are similar to other HEDT and lower-end systems we've tested thus far...

A new system call added to the very feature rich Linux 5.6 kernel is openat2() for more extensible behavior compared to the existing openat() functionality...

The Wine project's VKD3D initiative for translating Direct3D 12 support to Vulkan took another step forward today with patches for handling DXIL (Shader Model 6.0+) shaders with VKD3D, but the work in the current form may need to be re-worked...

LibreOffice 6.4 is out today as the latest feature update to this cross-platform, open-source office suite...

While developers are hard at work on Godot 4.0 with Vulkan support, that release won't be ready until mid-2020 so as a result Godot 3.2 is out today as their latest stable release and serving as a "long-term support" release until transitioning to Godot 4...

Intel's Andy Shevchenko sent in the x86 platform driver updates on Monday for the newly opened Linux 5.6 merge window. There is the never-ending work on dealing with quirky Windows-focused laptops to adding new Intel hardware support and other additions...

With LLVM Clang 9.0 and Linux 5.3 together it became possible to build the mainline Linux kernel with this non-GCC compiler. The x86_64 Linux kernel Clang-based kernel builds has continued to improve through newer kernel releases. This follows the mainline AArch64 (64-bit ARM) Linux kernel mainline build by Clang too, which has been of much interest by different hardware/software vendors. There hasn't been much Clang'ing kernel efforts for other architectures, but it turns out with Clang 10 and Linux 5.6 will be another working combination, this time for IBM s390...

The Time Namespace, which was originally proposed back in 2018 for allowing per-namespace offsets to the system clocks, has finally entered the mainline kernel in early 2020 with the in-development Linux 5.6 kernel...

Mozilla's Thunderbird mail client has been rather neglected the past several years with all the focus on the Firefox web browser, but as the next step forward for this mail/RSS client is now placing it under the newly-formed MZLA Technologies Corporation...

It turns out Sony is now maintaining the mainline Linux kernel's hid-sony input driver in an "official capacity now across various devices." This hid-sony driver is what traditionally has supported the various PlayStation controllers and other input devices for their hardware. But their newfound "official" support for this open-source input driver could lead to interesting predicaments...
