System76 published a statement today regarding the recent laws coming about in California and likely Colorado and New York too around requiring age verification on operating system accounts and ultimately exposing the information (or at least age brackets) to apps and websites. System76's position is interesting given that they sell Linux-loaded desktops, workstations and laptops plus being an operating system vendor with their in-house Pop!_OS distribution and COSMIC desktop environment...

Rust 1.94 was rolled out today as the newest routine stable update for the Rust programming language...

The layoffs and restructuring at Intel in 2025 caused unfortunate hits to their Linux/open-source engineering including various driver maintainers leaving and even their CPU temperature driver being orphaned for lack of maintainers. Sent out today were a number of additional updates to the MAINTAINERS file for the Linux kernel to reflect other Intel departures in recent months. Plus some of the Altera drivers have also been orphaned now for having no upstream maintainers...

With a number of file-system improvements in Linux 6.19 and more file-system optimizations in Linux 7.0, it's past due for running some fresh file-system benchmarks. Here is a look at how the prominent file-system contenders are performing on the latest Linux 7.0 development kernel.

The Radeon R300 series turns 24 years old this year and thanks to the open-source ATI R300 Gallium3D driver that began via reverse engineering, it's still continuing to see the occasional random fixes from the open-source community...

The talk this week among open-source projects from Linux distributions to app stores like Flathub is how to deal with California's latest insanity: the Digital Age Assurance Act. California's AB 1043 state law is mandating that operating systems -- Linux included -- collect age information during account setup and exposing that age to eligible apps beginning on 1 January 2027. That leaves much uncertainty for Linux distributions and other repositories/stores and more. Canonical issued a statement today to clarify that they basically don't have a solution to announce yet...

For the past few months have been an ambitious proposal to replace FBCON with the user-space KMSCON as the default VT console starting on Fedora 44. Unfortunately, this and a few other features have now been delayed to the Fedora 45 release six months later...

A request for comments (RFC) patch series was posted today to the Linux kernel mailing list to introduce the AMD Dynamic Power and Thermal Configuration Interface "DPTCi" driver. With this driver it would provide better upstream Linux kernel support for tuning the power / performance / thermals of modern Ryzen-powered gaming handheld devices. Though don't get too excited right away as the driver was assembled in part by AI that is already causing a bit of a ruckus on the LKML due to lack of disclosure...

Google announced today that beginning later this year they are moving the Chrome web browser from its four week release cycle down to a two week release cadence...

Over the past month I have been running a lot of Linux benchmarks on Intel's new Panther Lake using the Core Ultra X7 358H and its Xe3-based Arc B390 Graphics. The Arc B390 on Linux has been quite interesting with its OpenGL and Vulkan graphics performance compared to prior generations of Intel graphics plus the Intel Compute Runtime / OpenCL performance too. In today's article are more benchmarks of the latter in looking at the Intel Rendering Toolkit and OpenVINO AI performance on the Xe3 B390 Panther Lake graphics compared to prior Lunar Lake and Meteor Lake.

There is two weeks to go until the GNOME 50 stable release while out today is the release candidate of Mutter 50. This Mutter 50.rc release brings some exciting last-minute enhancements to this Wayland compositor...

A Linux driver has been published for the ARCTIC Fan Controller to be able to read fan speeds under Linux as well as setting the PWM fan speed for each of the ten fans supported by this controller. Making this driver all the more exciting is that ARCTIC Cooling is directly working on this driver rather than just being a community/third-party creation. Furthermore, ARCTIC Cooling is working on getting this driver to the upstream Linux kernel...

Ahead of the stable GIMP 3.2 release hopefully happening soon, GIMP 3.2 RC3 was released this evening for testing...

The AMD EPYC 9755 128-core Zen 5 server processor has been benchmarked a lot at Phoronix since the EPYC 9005 "Turin" launch as their top-end Zen 5 server processor with "full fat" cores compared to the denser Zen 5C cores that extend up to the EPYC 9965 at 192 cores. For those eyeing the 128 core per socket sweet spot, there is also the EPYC 9745 that is made up of 128 Zen 5C cores that allows for a 400 Watt TDP compared to the 500 Watt EPYC 9755. Today's benchmarking is comparing the EPYC 9745 and EPYC 9755 performance and power difference.

An important default kernel behavior change worth noting in advance for the upcoming Linux 7.1 kernel is that the system will attempt to power-off automatically if encountering any fatal ACPI errors. Up to now the Linux kernel has just logged ACPI fatal errors...

Last week with my ongoing testing of the in-development Linux 7.0 kernel I found nice performance improvements for PostgreSQL and other workloads when testing on a 128-core AMD EPYC 9755 "Turin" server. Curious if those wins were due to optimizations focused on better scalability with today's "big" servers, I also ran some comparison Linux 7.0 benchmarks on the smaller AMD EPYC 4005 class servers too. Some nice wins carried over...

Work is underway by 9elements on porting Coreboot plus AMD openSIL to the first-generation Ryzen 7000 series Framework 16 laptop and is expected to be followed by a similar port to the Framework 13 Gen1 laptop too...

Zlib-rs as the Rust programming language implementation of Zlib from the Trifetca Tech Foundation is out with a shiny new release (actually, releases) today...

ASUS desktop motherboards have been seeing broader sensor monitoring support on Linux in recent years. ASUS motherboards for Intel and AMD processors have been seeing more support added thanks to the open-source community with new additions to the likes of the ASUS-EC-Sensors driver and other hardware monitoring (HWMON) driver code. This is continuing for Linux 7.1...
