Last month ODROID announced an Intel-powered single board computer after their experimenting with a Ryzen SBC hadn't panned out for this company known for their high-performance ARM SBCs. The ODROID-H2 has begun shipping as this $111 USD Intel x86_64 quad-core board while for your viewing pleasure today are some initial performance benchmarks of this board.
Adding to the headaches around Linux 4.19 stable is an EXT4 file-system corruption issue that has yet to be sorted out.
When the Radeon RX 590 launched two weeks ago, Linux support wasn't anticipated to be a problem with it being yet another Polaris graphics card and largely unchanged from a driver perspective compared to the RX 580 and other Polaris cards the past few years. Sadly at least for some AIB RX 590 cards, that hasn't turned out to be the case.
For several months now the mainline LLVM Clang compiler code has offered Speculative Load Hardening (SLH) for the compiler-based approach for Spectre Variant One protection for critical software that might not be mitigated by hand against Spectre V1 vulnerabilities that can be picked up by Smatch and other utilities. The Clang compiler now has support for SLH on a function-by-function basis.
It looks like the mainline Linux 4.20 kernel within a few days will be playing nicely on more AMD hardware. In particular, the Raven Ridge Zen+Vega APUs that have been rather troublesome depending upon the BIOS/motherboard since their launch almost one year ago.

Making the rounds this morning is an ASRock forum post about a motherboard accidentally and repeatedly wiping out Linux Software RAID meta-data. A few Phoronix readers have also reported similar issues such as in the forums and Twitter. This appears to stem from an UEFI issue.
In the benchmarks earlier this month looking at the Talos II POWER9 dual 22-core performance its performance was compared to various AMD Threadripper and Intel Core i9 CPUs. They were used as comparison points since all of those CPUs sport four memory channels, including the Sforza POWER9 CPUs, while IBM caters the larger LaGrange/Monza POWER9 modules with eight memory channels as competition to Xeon and EPYC. But for those wondering how the POWER9 Sforza performance compares to Intel Xeon and AMD EPYC processors, here are some benchmarks.
LunarG has shipped the latest version of the Vulkan SDK that pulls in support for the many recently introduced extensions from VK_NV_ray_tracing to VK_EXT_pci_bus_info and VK_EXT_transform_feedback, among other recent vendor extensions. There is also bug fixes and improved validation coverage for this Vulkan SDK.

Here is a look at how the Linux kernel performance has evolved since Linux 4.10, which was released back in February of 2017, up through the current Linux 4.20 development cycle ahead of its debut at the end of December or early January. All of the Linux kernel benchmarks were done on the same venerable Intel Core i7 5960X system.

Vulkan 1.1.94 is out today as the latest update to this graphics and compute API. This latest refinement to Vulkan introduces two new extensions.
One of the most passionate topics by readers in the Phoronix Forums is the Rust programming language. For about one year now "RLSL" has been in the works as a Rust-based shading language that can compile into SPIR-V. While initially I held off on writing about it to see if it would be just another small toy project, RLSL has continued maturing and seeing new functionality added in.
While GCC 9 is releasing in early 2019, for those still depending upon last year's GCC 7 compiler series, the GCC 7.4 point release will soon be out.

Released this week was AMDVLK 2018.4.2 having been released this past week as the newest open-source AMD Vulkan driver code derived from their official Vulkan driver code-base but with using the AMDGPU LLVM compiler back-end over their proprietary shader compiler. For your latest Vulkan benchmark viewing pleasure is a look at this newest AMDVLK release compared to AMDGPU-PRO 18.40 (the same fundamental Vulkan driver but with the closed-source shader compiler) and then the RADV Vulkan drivers in the form of Mesa 18.2 stable and the now in-development Mesa 19.0. These four AMD Radeon Vulkan driver combinations were tested on Fiji, Polaris, and Vega graphics processors.

Released on Thursday was PHP 7.3 RC6 as the last planned pre-release for the upcoming PHP 7.3. Here are some benchmarks looking at the PHP 7.3 performance compared to PHP releases going back to the v5.5 series on a Linux server.
With Feral Interactive's modern Linux game ports that rely upon the Vulkan graphics API for rendering, the company usually lists the Radeon R9 285 as the minimum requirement. That's generally because the R9 285 "Tonga" is the first graphics card officially supported by the AMDGPU kernel driver, which is necessary for RADV Vulkan driver support, but with non-default options it's possible to get AMDGPU+RADV working on GCN 1.0 Southern Islands and GCN 1.1 Sea Islands graphics cards. Here are some benchmarks of that experimental GCN 1.0/1.1 Vulkan support using Feral's newest Linux game port, Total War: Warhammer II, in a 25-way AMD/NVIDIA graphics card comparison for Linux gaming.
