bMozilla has rolled out Firefox 145, a significant update that brings a range of usability, security and privacy enhancements, while marking a clear turning point by discontinuing official support for 32-bit Linux systems. For users on older hardware or legacy distros, this change means it’s time to consider moving to a 64-bit environment or opting for a supported version. Here’s a detailed look at what’s new, what’s changed, and what you need to know.

Linux hardware vendor Slimbook announced today the launch of the KDE Slimbook VII laptop to celebrate 8 years of collaboration with the KDE project in creating the best Plasma-powered Linux notebooks.

Initially upstreamed into the Linux 6.18 kernel is Tyr as a Rust-based GPU kernel driver for Arm Mali hardware. This is in effect a Rust alternative to the Panthor DRM kernel driver for newer Arm Mali GPUs with the Command Stream Firmware (CSF). With the latest development code for Tyr, it’s moved onto running the GNOME desktop and basic games like SuperTuxKart…

Xubuntu confirms a malicious ZIP was served in October and is switching to the Hugo static site generator to prevent similar attacks.

The Linux job market has reached unprecedented heights in 2025, with demand for professionals who possess Linux expertise continuing to surge across multiple technology sectors. Organizations worldwide are prioritizing candidates who can leverage Linux systems in cloud-native environments, AI operations, and DevOps workflows.

To avoid jumping into the directory to execute your local program or script, you can add their paths to the $PATH variable to access them from anywhere.

Project Hummingbird aims to remove the worry and streamline the deployment of secure container images for cloud-native teams.

The post Red Hat Project Hummingbird For CVE-Free, Ready-to-Deploy Container Images appeared first on FOSS Force.

Preliminary proposal is already provoking debateThe Python community is chewing over a new idea: allowing the C-based reference implementation, CPython, to incorporate Rust. It’s only at the “pre-PEP” stage, but it’s already sparked lively debate.…

Xen 4.21 is out today as the newest feature release for this open-source hypervisor backed by AMD, Arm, AWS, and other organizations. Plus with Xen’s use within automotive environments, Ford and Honda too…

The KDE Project released today KDE Plasma 6.5.3 as the third maintenance update to the latest KDE Plasma 6.5 desktop environment series with more improvements and bug fixes.

This week marks two years since the debut of the Ryzen Threadripper 7000 series processors. Given the occasion, I decided to revisit the Linux performance of the Threadripper 7980X compared to original benchmarks from November 2023 to see how the latest Linux software stack performs for these Zen 4 HEDT processors.

The Linux kernel
supports a large number of architectures.
Not all of those are supported by Linux distributions, but Debian does support
many of them, officially or unofficially. On October 26, Bastian Blank

opened a discussion about the minimum version of these architectures
that Debian should support: in particular, raising the de-facto minimum
versions in the next Debian release (“forky”). Thread participants were generally in favor of
keeping support for older architecture variants, but didn’t reach a firm
conclusion.

In mid-October, the Xubuntu
download site was compromised and had directed users to a malicious
zip file instead of the Torrent file that users expected. Elizabeth
K. Joseph has published
a postmortem of the incident, along with plans to avoid such a breach
in the future:

To be perfectly clear: this only impacted our website, and the torrent
links provided there.

If you downloaded or opened a file named “Xubuntu-Safe-Download.zip”
from the Xubuntu downloads page during this period, you should assume
it was malicious. We strongly recommend scanning your computer with a
trusted antivirus or anti-malware solution and deleting the file
immediately.

Nothing on cdimages.ubuntu.com or any of the other official Ubuntu
repositories was impacted, and our mirrors remained safe as long as
they were also mirroring from official resources.

None of the build systems, packages, or other components of Xubuntu
itself were impacted.

Recordings from the GStreamer
Conference 2025, held in London in late October, are now
available on the GStreamer Conferences Archive site. Includes the
GStreamer
State of the Union talk by Tim-Philipp Müller, State
of MPEG 2 Transport Stream (MPEG-TS) by Edward Hervey, and many
others.

Beginning yesterday and continuing today are several patch series beginning to lay the foundation in the AMDGPU kernel graphics driver for enabling some next-generation graphics IP. Due to the AMD graphics driver block by block enablement strategy and IP-based discovery adopted by their driver over the past few years, it’s not clear what this new hardware enablement is for whether it’s RDNA5 / UDNA or some RDNA4 refresh. In any event, the Linux driver enablement has begun…
