[$] Compiling Rust to readable C with Eurydice A few years ago, the only way to compile Rust code was using the rustc compiler with LLVM as a backend. Since then, several projects, including Mutabah's Rust Compiler (mrustc), GCC's Rust support (gccrs), rust_codegen_gcc, and Cranelift have made enormous progress on diversifying Rust's compiler implementations. The most recent such project, Eurydice, has a more ambitious goal: converting Rust code to clean C code. This is especially useful in high-assurance software, where existing verification and compliance tools expect C. Until such tools can be updated to work with Rust, Eurydice could provide a smoother transition for these projects, as well as a stepping-stone for environments that have a C compiler but no working Rust compiler. Eurydice has been used to compile some post-quantum-cryptography routines from Rust to C, for example. https://lwn.net/Articles/1055211/

The Award for Excellence in Open Source goes to Greg Kroah-Hartman Daniel Stenberg, the recipient of last year's Award for Excellence in Open Source from the European Open Source Academy, presented that award to this year's recipient: Greg Kroah-Hartman. It's impossible to overstate the importance of the work Greg has done on Linux. In software, innovation grabs headlines, but stability saves lives and livelihoods. Every Android phone, every web server, every critical system running Linux depends on Greg's meticulous work. He ensures that when hospitals, banks, governments, and individuals rely on Linux, it doesn't fail them. His work represents the highest form of service: unglamorous, relentless, and essential. https://lwn.net/Articles/1056699/

Three stable kernel updates The https://lwn.net/Articles/1056694/ , https://lwn.net/Articles/1056695/ , and https://lwn.net/Articles/1056696/ stable kernel updates have been released; each contains another set of important fixes. https://lwn.net/Articles/1056693/

A proposed governance structure for openSUSE https://en.opensuse.org/User:Jeff_mahoney , who holds a vice-president position at SUSE, has posted a detailed proposal for improving the governance of the openSUSE project. It's meant to be a way to move from governance by volume or persistence toward governance by legitimacy, transparency, and process - so that disagreements can be resolved fairly and the project can keep moving forward. Introducing structure and predictability means it easier for newcomers to the project to participate without needing to understand decades of accumulated history. It potentially could provide a clearer roadmap for developers to find a place to contribute. The stated purpose is to start a discussion; this is openSUSE, so he is likely to succeed. https://lwn.net/Articles/1056593/

[$] Sub-schedulers for sched_ext The https://lwn.net/Articles/922405/ (sched_ext) allows the installation of a custom CPU scheduler built as a set of BPF programs. Its merging for the 6.12 kernel release moved the kernel away from the "one scheduler fits all" approach that had been taken until then; now any system can have its own scheduler optimized for its workloads. Within any given machine, though, it's still "one scheduler fits all"; only one scheduler can be loaded for the system as a whole. The sched_ext sub-scheduler patch series from Tejun Heo aims to change that situation by allowing multiple CPU schedulers to run on a single system. https://lwn.net/Articles/1056014/

Mourning Didier Spaier We have received the sad news that Didier Spaier, maintainer of the blind-friendly Slackware-based Slint distribution, has recently passed away. Philippe Delavalade, who posted the announcement to the Slint mailing list, said: Early 2015, I asked on the slackware list if brltty could be added in the installer; Didier answered promptly that he could do it on slint. Afterwards, he worked hard so that slint became as accessible as possible for visually impaired people. You all know that all these years, he tried and succeeded to answer as quickly as possible to our issues and questions. He will be irreplaceable. https://lwn.net/Articles/1056384/

OSI pauses 2026 board election cycle The Open Source Initiative (OSI) has https://opensource.org/blog/2026-osi-elections-update that it will not be holding the 2026 spring board election. Instead, it will be creating a working group to "review and improve OSI's board member selection process" and provide recommendations by September 2026: The public election process was designed to gather community priorities and improve board member selection, while final appointments remained with the board. Over time, that nuance has become a source of understandable confusion for community members. Many reasonably expected elections to function as elections normally do, and in fact, the board has generally adopted the electorate's recommendations. When a process feels unclear, trust suffers. When trust suffers, engagement becomes harder. This is especially problematic for an organization whose mission depends on legitimacy and credibility. [...] OSI tried its experiment for the right reasons, but a variety of factors resulted in "elections" that are performatively democratic while being gameable and representative of only a small group, and we've learned from the results. Now we are making space to align our director selection process with our bylaws, to rebuild trust, and to develop better, more durable and truly representative participation in which the global stakeholder community can be heard. LWN covered the previous OSI election in March 2025. https://lwn.net/Articles/1056376/
