More than a decade after Apple acquired the CUPS source-code and its lead developer, that developer, Michael Sweet, recently parted ways with Apple.

Linus Torvalds has just released Linux 5.5 as stable.

MPV 0.32 is out today as the newest update to this open-source video player based on MPlayer.

Formally announced earlier this month was Kubuntu Focus as the most polished KDE laptop we've ever tested. Besides offering a great KDE desktop experience, the Kubuntu Focus offers high-end specs while now there is a slightly cheaper base model introduced.

Linux 5.5 is likely to be released later today and with that are many new features. But as soon as 5.5 is released it marks the opening of the Linux 5.6 merge window and this next kernel has us particularly exciting... It's certainly shaping up to be one of the most exciting kernel cycles in recent times with many blockbuster features and improvements.

Dracut that is used for generating the initramfs image on Linux distributions like Fedora / RHEL, Debian, openSUSE, and many other distributions could be much faster.

Fedora IoT already uses swap-on-ZRAM by default given IoT devices are often running with limited amounts of RAM, but for Fedora Workstation 33 the developers are looking at enabling SWAP-on-ZRAM by default for all new installations.

KDE developers were busy as always this week working to polish up the forthcoming KDE Plasma 5.18 and other areas of their open-source desktop stack.

The widely-used SQLite embedded database library saw its first major release of 2020 this week.

Earlier this month I wrote about Intel SST Core-Power patches as part of Intel's Speed Select's functionality for more control over per-core power/frequency behavior based upon the software running on each core. The "core-power" profile support appears ready now for Linux 5.6.

As shown yesterday the new video BIOS of the Radeon RX 5600 XT paired with the corrected SMC firmware on Linux yields impressive performance improvements that -- similar to Windows -- allows the card to compete better with NVIDIA's GeForce RTX 2060. For Linux users, activating the Valve-funded ACO compiler back-end for the Radeon "RADV" Vulkan driver helps turn up the competition even more.

It's already been over nine months since the release of Solus 4 while now this popular Linux desktop distribution has been succeeded by Solus 4.1

Patches written two months ago for Intel's ANV open-source Vulkan driver have now been merged ahead of the imminent Mesa 20.0 feature freeze and branching.

Some exciting news this week for Firefox users running on Wayland...

In addition to the AMD RadeonSI Gallium3D driver's on-disk shader cache and in-memory shader cache there is now a "live shader cache" to help with deduplication of compiled shader objects.

The release candidate of OPNsense 20.1 is available this weekend, the FreeBSD/HardenedBSD-based networking/firewall OS that forked from pfSense now a half-decade ago.

One of the features that didn't materialize in time for Wine 5.0 as the annual stable Wine release was the work-in-progress Vulkan back-end to WineD3D. Rather than going from Direct3D to OpenGL as WineD3D currently does, there has been efforts to introduce a Vulkan back-end similar to the likes of DXVK.

Coming a few weeks past DXVK 1.5.1 is now version 1.5.2 and it brings with it quite a number of improvements.

Weston 8.0 was released today as the newest version of this reference Wayland compositor.

Yesterday I put together some statistics on the AMD vs. Intel contributions to the upstream Linux kernel during the 2010s, but a request coming in off that was how do NVIDIA's contributions compare. Here is a look at the NVIDIA contributions to the Linux kernel over the past decade.

Everything is aligning that the Linux 5.5 kernel is likely to be released this coming Sunday rather than being pushed off for another week of testing.

As more last minute work for the upcoming Mesa 20.0 is initial OpenGL tessellation support for Intel's OpenSWR driver.

NVIDIA on Thursday introduced Nsight Graphics 2020.1 that to its profiling support can now handle OpenGL + Vulkan interoperability for games/applications making use of both APIs. While not many game engines / apps are yet using the likes of OpenGL 4.6 ARB_gl_spirv, Nsight is ready.

While the Linux 5.5 kernel isn't even released yet, it's ideally coming out on Sunday should there not be a one week delay. But in any event Arm's Will Deacon has already sent in the pull request of the ARM architecture changes for Linux 5.6.

The MIPS-based SGI Octane IRIX workstations were first introduced in the late 90's while recently there has been a resurgence in the work on getting these vintage PCs running off a mainline Linux kernel.

After missing their original target of transitioning to Intel Gallium3D by default for Mesa 19.3 as the preferred OpenGL Linux driver on Intel graphics hardware, this milestone has now been reached for Mesa 20.0!

ZFS On Linux 0.8.3 is out today as the first official update to ZoL since last September.

While the Linux 5.5 kernel is expected to be released as soon as this Sunday, a last minute change to the AMDGPU DRM driver makes the Renoir graphics no longer treated as experimental. With that, there is open-source support out-of-the-box rather than being hidden behind a kernel module flag.

In addition to WireGuard being part of "net-next" as the networking subsystem material targeting the upcoming Linux 5.6 cycle, there is another big last minute addition to the networking space: the Flow Queue PIE packet scheduler has been merged.

As last minute material for Mesa 20.0 is making Valve's "ACO" AMD compiler back-end for the RADV Vulkan driver in better shape for GFX6/GCN1.0 graphics hardware.

Driven by curiosity sake, here is a look at how the total number of AMD and Intel developers contributed to the upstream Linux kernel during the 2010s as well as the total number of commits each year from the respective hardware vendors.

LibreOffice 6.4 is set to be released in the coming days while succeeding that will now be LibreOffice 7.0.

Flatpak 1.6 was an exciting update for this Linux application sandboxing/distribution tech in that it started laying the foundation to support a paid app store but elsewhere in the code-base a security issue came about.

Last year Linux kernel developers began removing support for Intel's Memory Protection Extensions (MPX) and that looks like it will be finished up in the forthcoming Linux 5.6 cycle.

Red Hat Enterprise Linux 8.2 entered public beta this week as the latest installment to RHEL8.

As we have been eagerly talking about for the past week, the Linux kernel's k10temp driver was updated for better AMD CPU CCD temperatures and voltage/current reporting. Those improvements have been quickly evolving thanks to the work of the open-source community with AMD still sadly holding the datasheets concerning the power/temperature registers close to their vest. A new version of k10temp was sent out on Wednesday.

While Apple still isn't officially supporting the Vulkan graphics/compute API in remaining focused on their Metal drivers, MoltenVK at least has been updated for Vulkan 1.2 in allowing developers to target this Vulkan-to-Metal abstraction layer for macOS and iOS.

Mesa developers are planning to end feature work on Mesa 20.0 next week as this first quarter update to the Mesa 3D graphics stack.
