Developers working hard on the Kdenlive open-source video editor are preparing to unveil their significantly refactored code-base in the upcoming KDE Applications 18.08 release. But for helping weed out the bugs, you can now test an AppImage for this big release that is nearly two years in the making...

Back in March we looked at the cooling performance of Noctua's AMD EPYC heatsinks for cooling these Zen-based server processors. The Noctua heatsinks tested did a wonderful job testing those socket SP3 processors so when the Austrian company announced a few weeks ago their Xeon Scalable heatsink line-up, we decided it would be interesting to see how their latest Intel server heatsinks perform.

First of all, Happy Independence Day to the Phoronix readers in the United States. On this rather light day, here is a look back at the most popular Phoronix articles during the second quarter of the year. During Q2-2018 were 924 original news articles published with new content each and everyday and that's in addition to another 68 featured Linux hardware reviews / multi-page benchmark articles...

A few days back we reported on the Red hat progress with supporting WebRTC-based screen-casting under Wayland that's working both for KDE Plasma and GNOME Shell. Given all the concerns over the years in supporting screen sharing / remote desktop under Wayland and the bits only coming together recently, Red Hat's Jan Grulich has offered up a guide...

When it comes to the growing number of changes slated for Fedora 29, while most of the feature plans benefit all supported CPU architectures, there are also some ARM-specific improvements planned...

With the BUS1 in-kernel IPC mechanism continuing to be off in the distance as a potential successor to the current form of D-Bus, the BUS1 developers continue working on Dbus-Broker as the "Linux D-Bus Message Broker" that retains compatibility with the D-Bus specification while offering higher performance and greater scalability...

For those currently making use of Ubuntu 18.04 LTS with its default graphics stack (Linux 4.15 + Mesa 18.0) and are wondering if it makes sense upgrading to a newer version of the Linux kernel and/or Mesa, here is an extensive Mesa+AMDGPU comparison testing four graphics driver configurations across three popular AMD Radeon graphics cards.

The end of July marks one year since the release of OpenGL 4.6 but sadly it doesn't look like the Mesa drivers will meet that anniversary for having working open-source OpenGL 4.6 compliance in the mainline Mesa code-base...

In late May Spectre V4 was made public and coinciding with the public reveal was the Linux kernel patches for the Speculative Store Bypass Disable (SSBD) mode for mitigating this latest side-channel attack. For SSBD on Intel CPUs, updated microcode is required and those patched microcode files are now being delivered down through new BIOS updates from motherboard vendors. In recent days with seeing ASUS motherboards get the updated supported, I decided to run some initial Core i7 Coffeelake benchmarks with/without the SSBD support being enabled in the Linux kernel.

With the Linux 4.18 kernel development settling nicely, I've been ramping up tests lately on the Linux Git state. For those curious, here are some fresh benchmarks using the current AMD flagship EPYC processor of Linux 4.16, 4.17, and 4.18 Git...

Yet another notable change proposal for Fedora 29 is to "remove excessive linking", which could help program start-up times, but may be too late for happening with the current Fedora Linux release cycle...

The second release candidate of the upcoming NetBSD 8.0 is now available...

A few days back I wrote about some Intel open-source Vulkan "ANV" driver optimizations that really help the Skyrim game under DXVK with Wine to allow for a playable experience with Intel onboard graphics. Those patches have now been merged into Mesa 18.2...

Haiku OS continues working towards its long-awaited beta and there continues to be other improvements made for this BeOS-inspired platform...

It's been about three years since last carrying out any file-system performance benchmarks of Reiser4, but being curious how it stacks up against the current state of today's mainline Linux file-systems, here are some fresh performance tests of Reiser4 using the Linux 4.17 kernel. The Reiser4 performance was compared to Reiserfs, EXT4, Btrfs, XFS, and F2FS.

Fedora is planning to discontinue the POWER PPC64 architecture support within their Linux distribution as far as the big endian flavor is concerned. But PPC64LE (little endian) is where they will exclusively focus their POWER architecture attention...

It was just shy of four years that SUSE was effectively acquired by Micro Focus as yet another changing of the guard for this long-standing German enterprise Linux distribution. Now today it's been announced that a Swedish private equity fund will be acquiring SUSE...

Three years after Kolab Systems raised more than $100k USD to develop "RoundCube Next" as a next-generation mail and communication platform, there is little to show for it and no active development...

Last week we noted how some of the code to boot the RISC-V SiFive HiFive Unleashed development board was closed-source. That upset some in the Coreboot community with hoping for a more open development board built around the RISC-V open-source processor ISA. The good news is that SiFive will soon be releasing the necessary code for initialization as open-source...

A few days back I wrote about workarounds for getting FreeBSD running stable on AMD Ryzen via a script to adjust some of the CPU's MSRs based upon a recently-updated AMD revision guide. That script, which was making use of FreeBSD's cpucontrol utility for adjusting the bits, has now morphed into a kernel patch...

Earlier this month the Laminar Research crew responsible for the realistic, cross-platform X-Plane flight simulator presented at the FlightSimExpo about their work on porting the flight simulator to Vulkan and other ongoing improvements...
