Mark Surman, president of the Mozilla Corporation, has announced
leadership updates for Mozilla. This includes a Mozilla Leadership
Council made up of executives from each Mozilla organization, and new
board chairs for the not-for-profit Mozilla Foundation, the
Mozilla Corporation, and Mozilla.ai. The announcement also
indicates a desire to further “diversify” Mozilla’s focus:

We’ve recognized that Mozilla faces major headwinds in terms of both
financial growth and mission impact. While Firefox remains the core of
what we do, we also need to take steps to diversify: investing in
privacy-respecting advertising to grow new revenue in the near term;
developing trustworthy, open source AI to ensure technical and product
relevance in the mid term; and creating online fundraising campaigns
that will draw a bigger circle of supporters over the long
run. Mozilla’s impact and survival depend on us simultaneously
strengthening Firefox AND finding new sources of revenue AND
manifesting our mission in fresh ways. That is why we’re working hard
on all of these fronts.

Steven Rostedt recently posted

a patch set that could help improve the performance of certain user-space
applications by giving the scheduler more context about when they are safe to
interrupt. The patch set lets programs request a small grace window
before they can be interrupted so that they can relinquish any locks, decreasing the
amount of time that other threads have to spend waiting. Rostedt shared
performance numbers suggesting that the patch might cut the amount of time spent
acquiring locks in half for some programs — although, since his test was
specifically tuned for this case, real-world projects should expect a somewhat
less dramatic improvement. The change received some pushback from scheduler
maintainer Peter Zijlstra, who objected to the patch set’s approach.

Version
25.0.0 of the Mesa graphics library has been released. “The flashiest addition is probably the support for Vulkan 1.4 by Anv (Intel),
Asahi (Apple), Lavapipe (software), NVK (NVIDIA), PanVK (Mali), RADV (AMD),
and Turnip (Qualcomm).

Users can expect the usual flurry of improvements across all drivers and
components.“

Many of us enjoy uninterrupted access to mobile networks. However, in
remote areas or during emergencies, that connectivity may not always be
available. For such scenarios, Meshtastic offers a decentralized
wireless mesh network with open-source firmware that runs on affordable,
low-power devices.
At FOSDEM 2025, the Meshtastic
project was represented by one of its core developers, Thomas Göttgens, who
gave a talk, “Meshtastic
– off-grid communication for everyone“, in the Radio developer
room (devroom).

The Fedora Project has announced
two milestones in its journey to supporting the RISC-V architecture: a
dedicated RISC-V Koji build system instance is live in the Fedora data
center, and Fedora
41-based images are now available for RISC-V. It is also possible
to run Fedora RISC-V images using QEMU for those without supported
hardware.

Debian Developer Thomas Lange has written a blog post
in the attempt to help users find the right Debian image for their
systems.

It’s difficult to find the right Debian image. We have thousands of
ISO files and cloud images and we support multiple CPU architectures
and several download methods. The directory structure of our main
image server is like a maze, and our web pages for downloading are
also confusing.
