[$] Analyzing Rust programs with Charon

Nadrieril is a long-time Rust contributor, and the maintainer of the rustc pattern-matching infrastructure. During his involvement with Rust, he has noticed a problem with the usability of the language: it is difficult to automatically extract information from a Rust crate for use with other tooling. The Charon project aims to fix that by providing a stable API for accessing internal information from the Rust compiler.

[$] Evolving the LAVD scheduler from gaming to servers

The extensible scheduler class, which enables the creation of custom CPU schedulers with BPF, has led to a burst of innovation in this area; the LAVD scheduler has, perhaps, been one of the most noteworthy schedulers to emerge. Though it was originally designed for gaming applications, the LAVD scheduler has since grown to serve other types of workloads as well. At the 2026 edition of Kernel Recipes, Changwoo Min and Gavin Guo presented an overview of this scheduler and how it has evolved over time.

A new Raspberry Pi Desktop release is finally available for x86-64

Simon Long has announced a long-awaited release of Raspberry Pi OS, based on Debian 13 ("trixie"), for x86-64 systems. We managed to find the time to update the Desktop for the Buster and Bullseye releases of Debian, but then we all just got too busy with other things, and, while we left the Bullseye version on the website for anyone who wanted it, we simply didn't have time to release any newer versions. But people kept on asking for it – we get two or three emails every week asking when the PC Desktop will be updated, and we haven't had an answer, because we honestly didn't know when we might get a chance to do it. We've continually tried to allocate time to be able to work on this, but it hasn't been easy. [...] Earlier this year, we (or rather Serge) finally got the latest version of the Desktop running on top of a Debian Trixie image. It's now based on 64-bit Debian (the amd64 architecture) rather than the older 32-bit version, as Debian itself has stopped supporting 32-bit for PC
