A week ago I wrote about AI being used to help modernize Ubuntu's Error Tracker. Microsoft GitHub Copilot was tasked to help adapt its Cassandra database usage to modern standards. It's worked in some areas but even for a rather straight forward task, some of the generated functions ended up being "plain wrong" according to the developer involved...

On top of the Rust driver core changes and other Rust code for Linux 6.19, the modules infrastructure for this new kernel version is also bringing some new code. Surprisingly, it's taken until now for Rust kernel modules/drivers to support module parameters as is common practice for passing different options when booting the kernel or manually loading kernel drivers with extra non-default options...

Sent in for the Linux 6.19 merge window when it comes to the frame-buffer device "FBDEV" subsystem are just a set of "fixes" for FBDEV drivers and code clean-ups. But it does also include a new console font option for better supporting modern laptops with high density displays...

The Non-Volatile Memory Device (NVDIMM) subsystem updates were merged today for the in-development Linux 6.19 kernel. Most notable this cycle for the NVDIMM code is a new open-source driver addition courtesy of Microsoft...

FEX 2512 is out today as the newest monthly update for this software that enables running x86/x86_64 Linux binaries on ARM64 Linux, including the likes of Wine and Valve's Steam Play (Proton) for being able to run Windows games on 64-bit ARM Linux devices...

Flowblade 2.24 released today as the newest version of this open-source, non-linear video editing application. Flowblade 2.24 brings a number of refinements while also interesting is their commentary concerning the future with Wayland and GTK4 porting...

For anyone still relying on Solaris in production or just nostalgic Solaris users from the grand Sun Microsystems days, Solaris 11.4 SRU 87 was released by Oracle this week as one of the heavier stable release updates in recent memory...

Beyond the main set of Rust changes to land in Linux 6.19 earlier this week, as we near the end of the first week of two for the Linux 6.19 merge window... More Rust changes. This time around the driver core updates for the kernel bring a number of Rust changes...

It was a busy start of December for KDE Plasma developers in working out several hardware fixes for the current Plasma 6.5 series while also working on new Plasma 6.6 features like the per-DRM-plane color pipelines...

There have been many Intel Linux/open-source software engineers to leave the company over the past year among other setbacks for their Linux/open-source initiatives. Announced this Friday night is one of their highest profile departures of the year as it pertains to their Linux efforts...

For Linux 6.19 as what will be the first stable kernel release of 2026, the IEEE-1394 Firewire stack continues dealing with device quirks and improving support for different Firewire-connected devices. In 2026 is also when the Linux Firewire maintainer plans to begin recommending users migrate away from the IEEE-1394 bus followed by closing the Linux Firewire efforts in 2029...

The IO_uring and block subsystem changes have been merged for the Linux 6.19 merge window with a few improvements worth highlighting this cycle...

Finnish company Jolla started out 14 years ago where Nokia left off with MeeGo and developed Sailfish OS as a new Linux smartphone platform. Jolla released their first smartphone in 2013 after crowdfunding but ultimately the Sailfish OS focus the past number of years now has been offering their software stack for use on other smartphone devices. But now it seems they are trying again with a new crowd-funded smartphone...

Nearly four years have passed since AMD launched their EPYC Milan-X processors with 3D V-Cache. When recently rearranging some servers in the lab and realizing the four year anniversary was coming up in March, curiosity got the best of me in wondering where the Linux performance and energy efficiency on Milan-X is now with the latest Linux software stack compared to the numbers when Milan-X launched back in March 2022.

Intel engineer Tim Chen has sent out a second version of the proposed Cache Aware Scheduling patches for the Linux kernel to enhance the CPU performance of modern processors sporting multiple cache domains...

Venus is the VirtIO-GPU driver that allows for Vulkan support within guest virtual machines permitting sufficient host driver support and other requirements in place with hypervisors like CrosVM and QEMU. The Venus driver now supports Vulkan's mesh shader capabilities and in turn advances the DXVK-Proton support for Linux gaming within VMs...
