Ezarcher is a set of Arch-based live Linux distribution with a number of popular desktops, including Cinnamon, GNOME, KDE Plasma, LXQt, MATE and Xfce. All desktop environments are provided in their default upstream state, without any customisations. The distribution can be installed to a hard disk using either the text-mode "archinstall" method or the graphical Calamares system installer. Unlike Arch Linux which generally deploys the latest stable kernel, Ezarcher runs exclusively on the long-term supported variant of the Linux kernel. Besides the distribution, the project also offers build templates to guide users to customise and re-build their own live medium with one of the desktop environments on offer.

CalamaroOS is a Gentoo-based Linux distribution for the desktop, using either KDE Plasma or Xfce desktop environment. It features the Calamares system installer, out-of-the-box support for Flatpak packages, support for BTRFS, XFS and F2FS filesystems, and the systemd software suite for system and service management. The project's goal is to bring the power of Gentoo Linux to an average user by eliminating the complex and time-consuming process associated with the classic Gentoo install method.

Hardened Slarpx is a Debian-based, security-oriented Linux distribution. It uses a multi-layered defense model with aggressive mitigations and extensive kernel-level hardening. Due to its highly restrictive firewall policy, anonymization tools and certain network protocols are intentionally unsupported. It includes three custom runtime security modules - Poison, Xennytsu and Silencer. Beyond passive hardening, Slarpx also focuses on active intervention, sabotage and destruction of attack paths when necessary. The distribution boots directly into the standard Debian system installer and, by default, does not include any desktop environment or window manager.

GhostBSD is a user-friendly desktop operating system based on FreeBSD. Its default desktop is MATE, but a separate community edition with Xfce is available too. It also features a selection of commonly used software, a rolling-release development model, and a bootable live image with an intuitive graphical system installer.

Solus is a Linux distribution built from scratch. It uses a forked version of the PiSi package manager, maintained as "eopkg" within Solus, and its flagship edition uses the Budgie desktop environment. Budgie was originally developed-in-house, but is now maintained as a separate project by the Buddies of Budgie team. Solus is available in GNOME, KDE Plasma and Xfce editions.

Synex is a GNU/Linux distribution based on Debian's "Stable" branch, developed with the official Debian Live Build tool. It offers four separate desktop options with GNOME, LXDE, KDE Plasma and Xfce, all of which are composed of a rather frugal set of applications in its default state, without any development tools or offices suites. Some of the distribution's main features include Calamares installer with support for both BIOS and UEFI, CUPS integration for printing and network support, out-of-the box support for Flatpak applications, official NVIDIA driver installation assistant with support for both X11 and Wayland, and additional repositories containing Microsoft Edge, OnlyOffice and Zabbix.

Greg Kroah-Hartman has announced the release of the 6.19.13, 6.18.23, 6.12.82, 6.6.135, 6.1.169, 5.15.203, and 5.10.253 stable kernels. Each contains a number of important fixes throughout the tree; users are advised to upgrade.

ENux is a desktop Linux distribution based on Debian's "Stable" branch. It integrated Bedrock Linux, a project developing scripts that mix-and-match components from various Linux distributions and integrate them into one largely cohesive system. ENux's main claim to fame is support for a large range of popular package management tools that exist in the Linux ecosystem, including apk (Alpine Linux), dpkg/apt (Debian), emerge/portage (Gentoo), nix (NixOS), pacman (Arch Linux), rpm/dnf (Fedora), xbps (Void) and zypper (openSUSE) via the unified pmm tool (from Bedrock Linux). The distribution uses the Xfce desktop and substitutes Debian's long-term supported Linux kernel with a more up-to-date version.

BigLinux is a Brazilian Linux distribution localised into Brazilian Portuguese (with support for English). It is was originally based on Kubuntu, but starting from 2017 the distribution was re-born based on deepin. It then offered two desktop environments - Cinnamon and Deepin. In 2021 the distribution switched bases and desktop environments again, migrating to Manjaro Linux and using the KDE Plasma desktop.

Shor's algorithm is the main practical example of an algorithm that runs more quickly on a quantum computer than a classical computer — at least in theory. Shor's algorithm allows large numbers to be factored into their component prime factors quickly. In reality, existing quantum computers do not have nearly enough memory to factor interesting numbers using Shor's algorithm, despite decades of research. A new paper provides a major step in that direction, however. While still impractical on today's quantum computers, the recent discovery cuts the amount of memory needed to attack 256-bit elliptic-curve cryptography by a factor of 20. More interesting, however, is that the researchers chose to publish a zero-knowledge proof demonstrating that they know a quantum circuit that shows these improvements, rather than publishing the actual knowledge of how to do it.

One of the more significant changes in the 7.0 kernel release is to use the lazy-preemption mode by default in the CPU scheduler. The scheduler developers have wanted to reduce the number of preemption modes for years, and lazy preemption looks like a step toward that goal. But then there came this report from Salvatore Dipietro that lazy preemption caused a 50% performance regression on a PostgreSQL benchmark. Investigation showed that the situation is not actually so grave, but the episode highlights just how sensitive some workloads can be to configuration changes; there may be surprises in store for other users as well.
