Slimbook OS is an Ubuntu-based Linux distribution customised for the Slimbook line of Linux computers assembled in Spain. It offers a choice of GNOME or KDE Plasma desktops on a single ISO image which also includes some custom extensions and utilities. The distribution provides its own repositories for some software, prioritising DEB and Flatpak packages over Ubuntu's snap options. Some of the other interesting features of Slimbook OS include touchpad gestures (enabled by default), Slimbook service notifications, window tiling, the Terminator terminal emulator, a Ulauncher application for fast searching, and a day/night mode switcher.
William Woodruff, better known online as "yossarian", has published
a blog post to make the case that users should not place their trust
in trusted
publishing:
Trusted Publishing is a mechanism for establishing trust between an
external machine identity (like a CI/CD workflow) and one or more
projects on a package index/registry. The "trust" in "Trusted
Publishing" refers to that trust relationship, and not to anything
else.
It is not, and cannot be, a signal for package trust or
quality. You cannot use it to determine whether a package is safe or
"good," and PyPI consciously stymies attempts to misuse it for that
purpose by not rendering it as a "green checkmark" or anything else of
the sort.
Or as another framing: Trusted Publishing is just a form of
authentication. It doesn't tell you anything other than that an upload
was authenticated, which all uploads to PyPI are.
LWN covered trusted
publishing in June.
deepin (formerly, Deepin, Linux Deepin, Hiweed GNU/Linux) is a Debian-based distribution (it was Ubuntu-based until version 15 released in late 2015) that aims to provide an elegant, user-friendly and reliable operating system. It does not only include the best the open source world has to offer, but it has also created its own desktop environment called DDE or Deepin Desktop Environment which is based on the Qt 5 toolkit. Deepin focuses much of its attention on intuitive design. Its home-grown applications, like Deepin Software Centre, DMusic and DPlayer are tailored to the average user. Being easy to install and use, deepin can be a good Windows alternative for office and home use.
Puranjay Mohan shared some of the
work he's been doing recently on improving the
performance of read-copy-update (RCU) at the 2026
Linux
Storage, Filesystem, Memory-Management, and BPF Summit; his talk would have
been nice context to have earlier in the day when Harry Yoo and Alexei
Starovoitov led a session about the
new kmalloc_nolock() function that
allows for lockless allocation from any kernel context, and which interacts with
the RCU subsystem to allow that. This article therefore covers the two sessions
together and in the reverse order, to provide that missing context.

Version:next-20260707 (linux-next)
Released:2026-07-07
OpenSSH 10.4 has been released. In addition to a number of security
and bug fixes, there are a few notable changes; this release adds
experimental support for a composite post-quantum signature scheme
combining ML-DSA 44 and Ed25519 as described in this
IETF draft. With 10.4, if OpenSSH is compiled with sandbox support
it will fail on Linux systems that have not enabled SECCOMP
or NO_NEW_PRIVS; prior to this release, sshd would log an error
but continue operation. See the release notes for
a full list of changes.
KibaOS is a minimalist and lightweight desktop Linux distribution and live image based on Arch Linux and featuring a customised Budgie desktop. In its default state it contains a very limited set of applications. The distribution can be installed to a hard disk using the Calamares system installer. The goal of KibaOS is to provide a clean, modern and visually consistent out-of-the-box experience without requiring any post-install configuration.
Version:next-20260706 (linux-next)
Released:2026-07-06
Conversations about the kernel's filesystem implementations often involve a
layer called "iomap", but relatively few people can reliably say what iomap
actually is. That is just the kind of gap that LWN exists to fill. In
short, iomap handles the mapping between data in the filesystem space
(identified by a file of interest, and an offset within that file) and in
the storage space (which may be a memory location, or a set of blocks on a
storage device). Using that mapping, iomap handles a long list of common,
filesystem-related tasks, allowing a lot of boilerplate code to be removed
from individual filesystem implementations.

The
7.2-rc2 kernel prepatch is out for
testing. Linus said: "It's Sunday afternoon, and rc2 is out. Things
look very normal - it's not a small rc2, but it's in line with recent
releases, and slightly smaller than rc2 was in 7.1. Let's see how that all
continues, but so far so good."
Linux Q83 is a desktop Linux distribution based on Debian's "Stable" branch. Depending on the edition, it comes either with the Cinnamon desktop environment (a fork of GNOME created by Linux Mint), or COSMIC (a modern graphical desktop interface written in the Rust programming language, developed by System76). The distribution is available for Raspberry Pi and Radxa Orion O6 single-board computers, as well as standard desktops and workstations. Linux Q83 also comes with its own lightweight and resource-efficient web browser called W3.
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.
Bluestar Linux is a GNU/Linux distribution that is based on Arch Linux. The Bluestar distribution features up to date packages, a full range of desktop and multimedia software in the default installation and a live desktop DVD.
Soplos Linux is a set of desktop-oriented Linux distributions based on Debian's "Testing" featuring several popular desktop environments. It offers rolling updates, up-to-date software, a relatively lightweight and customisable desktop, compatibility with older hardware, and various speed and performance optimisation features. The distribution ships with a number of custom applications, such as Soplos Theme Manager, Soplos Plymouth Manager, Soplos Docklike (for adding and removing applications in the dock) and Soplos GRUB Editor.
ArchEZ (formerly ZestISO) is a rolling-release desktop Linux distribution based on Arch Linux. It comes in three editions, with the "KDE Gaming" variant designed for modern computers and with gaming and multimedia software as well as HDR (High Dynamic Range) video support included, while "Xfce" and "IceWM" are lightweight options designed for older systems. The "KDE Gaming" flavour also provides the Wine compatibility layer for running some Windows games and programs and offers support for Microsoft's NTFS volumes. ArchEZ uses its own graphical installation wizard called "ArchEZ Installer".
