mklinux lets one machine run several independent Linux kernels at the same time on bare metal, without a hypervisor. A host kernel owns a pool of CPUs, memory and PCI devices, carves that pool into instances, and boots a spawn kernel into each instance through kexec_file_load(). Every spawn kernel runs natively on its own CPUs, its own physical memory and its own devices. Nothing is emulated and nothing is trapped; the only thing shared is what you choose to share.

Note that this is not the old MkLinux, which was a port to PowerPC Macintosh systems.

Remind is a command-line calendar and alarm program, with an optional Tk-based graphical interface, for Linux and Unix-like operating systems. It has its own scripting language that allows users to create reminders that are difficult (if not impossible) to specify in other calendaring programs. It is wholly unsuitable for use in corporate environments that require calendar sharing and exchanging meeting invitations; however, it may be precisely the calendaring tool for users who prefer the command line and fast, flexible tools that can help keep track of messy schedules.

Vanilla OS 3, an immutable desktop Linux distribution, has been released. Notable changes in this release include support for Arm64, introduction of a Vanilla OS SDK, a rewrite of the Apx package manager using the new SDK, and much more. LWN covered Vanilla OS 2 in 2024.

Practical quantum computers have been ten years away for the last several decades. Now, however, it's beginning to look as though they will be possible in just a few years. Recent research with obfuscated results demonstrated much lower memory requirements to factor ECDSA keys on a quantum computer, with work by other researchers in the open more than halving memory use compared to the state of the art in 2023. At the same time, computer manufacturers are boasting quantum processors that retain viable superpositions over longer periods. Given how slowly software updates filter out to stable systems, it's worth looking at what configuration changes and protocol updates are needed to be safe from quantum computers now.

Version 31.1 of the Emacs editor has been released. There is a long list of changes including the removal of the Emacs dumper, a new user Lisp directory feature, a "Send to..." menu item in context-menu-mode, and many other changes; see the NEWS file for more information. Mickey Petersen, author of Mastering Emacs, also has a rundown of some of the quality-of-life features appearing in this release.

Quickshell is a toolkit for building desktop components, such as toolbars or menus. It uses QML, which is a declarative language for designing GUI applications. Quickshell helps developers create graphical tools for common desktop use cases with a focus on ease of development. It offers a convenient method for writing user interfaces and has been adopted by a number of projects, such as caelestia-shell and DankMaterialShell, that provide desktop environments for minimal window managers like Sway and niri.

Version 26.08 of the KDE Gear collection of applications has been released. Notable changes in this release include improvements in the signing features of Okular, improved file-grouping features in the Dolphin file manager, and a number of enhancements to the Kdenlive video editor. See the changelog for a full list of updates, enhancements, and bug fixes.

Furthermore, we discovered that the popular arrayref crate had recently been republished and made to depend on this crate, with the most recent versions yanked. We have removed the malicious version and unyanked the maliciously-yanked versions. Other crates by that author (internment, append-only-vec) were also affected so we have done the same for those, and locked the account as a precaution. We do not believe the author of arrayref to be acting maliciously, but their computer or credentials are likely compromised, and we are attempting to contact them.

Version 6.1.0 of the RPM Package Manager has been released. Notable changes include the ability to provide modifiers to RPM macros at definition time, improved build and verification error handling, support for signing files with PKCS11 tokens using rpmsign, as well as the addition of several new man pages. The 6.1.0 release also debuts a new release model inspired by the Linux kernel's.
