OpenCV 4.0 is now officially out as the widely-used real-time computer vision library.

Linus Torvalds just announced the release of Linux 4.20-rc3 as his weekly test release update to the in-development Linux 4.20.

It's been a busy past few days of benchmarking after discovering earlier this week the Linux 4.20 performance was dropping, bisecting the cause to be the introduction of STIBP for cross-hyperthread Spectre V2 mitigation, and seeing just how significant is the impact. Here are my latest tests and findings.

Continuing to make Sunday mornings more entertaining are new Vulkan documentation updates on their weekly-ish update cycle.

LibreOffice 6.2 was branched from master this weekend and the first beta release tagged for this open-source, cross-platform office suite.

Google is also getting more Android vendors moving over to using DRM/KMS drivers to power their graphics/display.

At this week's Linux Plumbers Conference, David Airlie began talking about the possibility of a vendor-neutral compute stack across Intel, Radeon, and NVIDIA GPU platforms that could potentially take on NVIDIA's CUDA dominance.

While Con Kolivas' kernel patch series decided to do away with BFQ support, the GNOME-aligned Endless OS Linux distribution has decided to do the opposite in move from CFQ as the default I/O scheduler over to BFQ.

Earlier this month AMD quietly released a new version of their Optimizing C/C++ compiler in the form of AOCC 1.3. This new compiler release has more Zen tuning to try to squeeze even more performance out of Ryzen/EPYC systems when using their LLVM-based compiler.

Following the recent application period, Outreachy on Thursday announced the dozens of selected participants who will have a $5500 USD paid internship the next few months for working on open-source projects.

Back in September Code Sourcery / Mentor Graphics posted the Radeon GCC back-end they have been developing with the cooperation of AMD. This is for allowing the GCC compiler to eventually offload nicely to Radeon GPUs with its different programming languages and supported parallel programming models, particularly with OpenMP and OpenACC in mind. But for now this patch series just works with single-threaded C and Fortran programs. The second version of this port was posted for review.

Ubuntu's little known EGMDE example Mir desktop that is mostly a proving grounds for Mir development is now receiving support for XWayland for being able to run X11 applications within this example environment.

While the Radeon RX 590 that launched this week is just yet another Polaris refresh, it turns out the open-source AMD Linux graphics driver stack isn't yet playing well with retail RX 590 graphics cards. This is quite a surprise considering the PCI ID was picked up months ago and the mature Polaris Linux driver support for quite a while now, but could be like the rough Raven Ridge Linux experience where the production cards with the shipping vBIOS isn't what the developers encountered during their pre-production driver enablement.

GNOME 3.31.2 is out this Friday as the latest development release in the trek towards next March's GNOME 3.32 release.

Feral Interactive has just announced that Total War: WARHAMMER II will be released for Linux (and macOS) next week.

After releasing the Raspberry Pi 3 Model A+ yesterday, the Raspberry Pi Foundation today announced Raspbian 2018-11-13 as the latest update to their Debian-based Linux distribution for these low-cost ARM SBCs.

While we know ROCm 2.0 is coming out before year's end and that will have many improvements like complete OpenCL 2.0 support, ROCm 1.9.2 is out today as the latest stable release for this Radeon Open Compute stack.

Last night I published some benchmarks after finding Linux 4.20 is regressing in several workloads compared to Linux 4.18/4.19 and at least was affecting Intel Core i9 "HEDT" boxes. Here are more affected workloads regressing on Linux 4.20 and it's not just limited to high-end hardware.

There are many Sandy Bridge era motherboards that have been freed by Coreboot while if you are looking for more options on something (slightly) newer, a micro-ATX Haswell-era motherboard from ASRock now works under this open-source BIOS implementation.

As part of The Qt Company's ongoing improvements to their tool-kit and with Qt 5.12 being an LTS release, this cycle they focused a lot on improving the performance.

After what feels like an eternity in waiting years for Mozilla to ship their Firefox web-browser with native Wayland support enabled, their latest Firefox Nightly builds have achieved this milestone.

Being well past the Linux 4.20 merge window I have moved onto benchmarking more of this development version of the Linux kernel. Unfortunately, there are some clear performance regressions.

Last month Oracle rolled out the public beta of VirtualBox 6.0 though didn't include many user-facing changes. They have now rolled out a second beta that does add in a few more features.

For those using the NVIDIA long-lived 410 Linux driver series over the in-beta 415.xx driver series, the 410.78 driver release is out today as the newest stable binary driver build.

The RadeonSI OpenGL driver offered Vega primitive binning support the past year followed by the RADV Vulkan driver, but it hadn't been enabled by default. Those working on the RADV driver are now planning on unconditionally enabling this Vega performance optimization for up to a few percent performance boost.

It's now been nearly one year since longtime Nouveau contributor Karol Herbst joined Red Hat where one of his big projects has been working on OpenCL support for this open-source NVIDIA driver by bringing up NIR/SPIR-V support and making the necessary improvements for allowing OpenCL kernels to be represented in that IR commonly used by the Mesa drivers. The work still isn't yet in Mesa Git, but Karol this week sent out his newest patches.

PHP developers unanimously approved and already merged support for the new "preloading" concept for this web server language. PHP preloading basically allows loading PHP code that persists as long as the web server is running and that code will always be ready for each subsequent web request, which in some cases will dramatically speed-up the PHP performance on web servers.
