Linux users who have Secure Boot enabled on their systems rely on certificates issued by Microsoft to verify the software used to boot a system is trusted by the user. One of those certificates expired recently, but that will not cause systems that are able to boot to stop doing so. There are situations where the expiration may cause problems, however, and the window for relying on existing signed binaries is shorter than it might appear. Users and administrators will want to stay on top of these changes. Over the last year, part of my job at Microsoft has been to work on this problem. LWN wrote about the certificate expiration in July 2025, and this article follows up with where we are now.

Dee Harris has published a summary of the recent "fireside chat" featuring Creative Commons founders Hal Abelson, Lawrence (Larry) Lessig, Molly Van Houweling, and Glenn Otis Brown. The chat was to mark the 25th anniversary of Creative Commons and included a look back at its history as well as a look at the landscape today:

Twenty-five years ago, a small group of people made a bet. They believed that if you gave creators a simple set of tools and licenses in language that a lawyer, a machine, and a human could all read, millions of people might choose to share their work with the world instead of locking it down.

The video of the chat is available on YouTube.

Git maintainer Junio Hamano has announced Git 2.55.0, which has non-merge commits from 100 people; 33 of those are first-time contributors to the project. LWN recently covered some of the noteworthy changes in 2.55, including new features for the experimental "git history" command, addition of the Git fsmonitor daemon for Linux systems, and more.

The xsnow application, which generates an animated snowfall effect (and other pleasant diversions) for X11 desktops, does not seem like an obvious channel for political statements. Nevertheless, xsnow's maintainer seems to have included a political protest in the program: an Easter egg that is triggered when the program's language is set to Russia ("ru"). One user has complained that this functionality should be removed from the Debian xsnow package, but Debian does not seem to have any rules that forbid such a feature outright.

The Kubernetes project has published a blog post explaining its AI policy:

The main problem is that AI has made generating code fast but there has been very little improvement in maintaining code bases. In this post, we will highlight the ways the Kubernetes community is adapting to the world of AI assisted coding.

The first step of this journey was to develop an AI policy. This seems mundane and bureaucratic but there were many PRs that derailed into discussions around AI usage. The AI policy helps steer the conversation around the project's stance on AI and provides a clear signal to contributors on how to use these tools responsibly.

Of note, the project requires disclosure when AI tools have been used to assist in the creation of a contribution but forbids the use of listing AI as a co-author or including "assisted-by" or "co-developed" trailers to attribute work to an LLM tool.

Mageia 10 has been released with the 6.18 Linux kernel, DNF 5.4.0, RPM 4.20.1, and an increase in hardware requirements for x86 32-bit systems; users now need a CPU with SSE2 features. See the release notes for a full list of updates, and the errata page for known problems.
