An Open Letter To Solus From Its Founder Ikey Doherty

Solus, the promising Linux distribution started back in 2015 by Ikey Doherty that led to the creation of its own "Budgie" desktop, has been without its founder since this summer. While the circumstances under his decision to fade away from the project aren't clear, he is well and has shared this message to relay with the community.

Linux Kernel Developers Begin Figuring Out Vendor-Specific RISC-V Code

With the increasingly popular RISC-V open-source processor instruction set architecture (ISA), there is the possibility for vendor-specific instruction set extensions. At this point the kernel has no infrastructure in place for its RISC-V port to allow for such bits, but that is being worked on as part of bringing up AndeStar RISC-V CPUs under the Linux kernel.

Steam Survey Reports The Latest Linux Gaming Marketshare For October

October was very interesting for Linux gaming with no AAA native game ports released but a heck of a lot more Windows games are now running nicely on Linux thanks to Steam Play / Proton / DXVK. So it's quite interesting to see Valve's just-published monthly Steam Survey results for the month prior.

NVIDIA Stabilizes Its Vulkan/OpenGL Ray-Tracing Extension

It was just in mid-September that NVIDIA introduced its ray-tracing extension for Vulkan as VK_NVX_raytracing with it debuting as an "experimental" feature along with OpenGL/GLSL functionality. Already they seem happy with the design that it's being promoted to stable.

Zink For OpenGL-Over-Vulkan Currently Supports GL 2.1 But Making Progress

The Zink Gallium3D driver that is implementing OpenGL over Vulkan and using Mesa's Gallium3D driver infrastructure is beginning to run more games, work under Wayland, and more. There still is a long road ahead but at least it's becoming usable for early testers and those wishing to experiment with this project.

Intel Core i9 9900K Spectre Mitigation Benchmarks

One of the benefits with the recently launched Core i9 9900K is hardware-based mitigations for Meltdown and L1TF/Foreshadow vulnerabilities. but mitigations are still needed for the other Spectre vulnerabilities. In this article is a look at the performance impact of still needing generic Retpolines via IBPB IBRS firmware for Spectre V2 and Speculative Store Bypass disabling (SSBD) for Spectre V4.

The AMD Threadripper ECC DDR4-2666 Testing That Wasn't

Recently in our forums there has been a lot of interest in Threadripper 2 builds using ECC DDR4 memory and the impact on performance, especially now with the Threadripper 2 family being rounded out by the 2920X and 2970WX. So I set out to do some DDR4-2666 ECC UDIMM testing with Threadripper 2, but that hasn't turned out well.

Trying To Make Ubuntu 18.10 Run As Fast As Intel's Clear Linux

With the recent six-way Linux OS tests on the Core i9 9900K there was once again a number of users questioning the optimizations by Clear Linux out of Intel's Open-Source Technology Center and remarks whether changing the compiler flags, CPU frequency scaling governor, or other settings would allow other distributions to trivially replicate its performance. Here's a look at some tweaked Ubuntu 18.10 Cosmic Cuttlefish benchmarks against the latest Intel Clear Linux rolling-release from this i9-9900K 8-core / 16-thread desktop system.

Elementary's Pantheon Desktop Update Proposed For Fedora 30

Fedora Workstation 30 will continue to use the GNOME Shell by default (more than likely, GNOME 3.32) but adding to the list of alternative desktop environments could be the elementaryOS' Pantheon Desktop. Pantheon has been available for a few releases on Fedora, but this change proposal is about upgrading the desktop.
