The restartable sequences feature, which was added to the 4.18 kernel in 2018, exists to enable better performance in certain types of threaded applications. While there are users for restartable sequences, they tend to be relatively specialized code; this is not a tool that most application developers reach for. Over time, though, the use of restartable sequences has grown, and it looks to grow further as the feature is tied to new capabilities provided by the kernel. As restartable sequences become less of a niche feature, though, some problems have turned up; fixing one of them may involve an ABI change visible in user space.

SmartOS is an open-source UNIX-like operating system based on illumos, a community fork of OpenSolaris. It features four technologies - ZFS (a combined file system and logical volume manager), DTrace (a dynamic tracing framework for troubleshooting kernel and application problems), Zones (a lightweight virtualisation solution), KVM and bhyve (two full virtualisation solutions for running a variety of guest operating systems, including Linux, Windows, BSD and Plan9). SmartOS is designed to be particularly suitable for building clouds and generating appliances.

The Amnesic Incognito Live System (Tails) is a Debian-based live DVD/USB with the goal of providing complete Internet anonymity for the user. The product ships with several Internet applications, including web browser, IRC client, mail client and instant messenger, all pre-configured with security in mind and with all traffic anonymised. To achieve this, Incognito uses the Tor network to make Internet traffic very hard to trace.

The National Institute of Standards and Technology (NIST) has finalized a lightweight cryptography standard to protect even the smallest networked devices from cyberattacks.

Published as Ascon-Based Lightweight Cryptography Standards for Constrained Devices (NIST Special Publication 800-232), the standard offers tools for securing data created and transmitted by billions of IoT devices, along with other small electronics such as RFID tags and medical implants.

OSMC (formerly Raspbmc) is a Debian-based minimal Linux distribution that brings the Kodi media centre software to a Raspberry Pi, Apple TV and Vero devices. This device has an excellent form factor and enough power to handle media playback, making it an ideal component in a low-cost HTPC (Home Theatre Personal Computer) setup, yet delivering the same Kodi experience that can be enjoyed on much more costly platforms.

Voyager Live is an Xubuntu-based distribution and live DVD showcasing the Xfce desktop environment. Its features include the Avant Window Navigator or AWN (a dock-like navigation bar), Conky (a program which displays useful information on the desktop), and over 300 photographs and animations that can be used as desktop backgrounds. The project also develops several other editions of Voyager Live - a "GE" edition with GNOME Shell, a "GS" variant for Gamers, and a separately-maintained flavour based on Debian's "stable" branch.

• Front: Debian; CPython; huge zero folio; kexec handover; FHS; Koka programming language
• Briefs: PyPI domain checks; Firefox 142.0; Git v2.51; Ghostty; LibreOffice 25.8; Zig 0.15.1; Quotes; ...
• Announcements: Newsletters, conferences, security updates, patches, and more.

The Zig project has announced version 0.15.1 of the language. The release, much like the last one, includes incremental progress toward the goal of completely dropping LLVM and improving compile time, as well as a handful of breaking changes as the language team wrestles with past API design. The biggest change this time around is to the standard library Reader and Writer interfaces, which have been completely rearranged in the name of performance and reducing unneeded copies.

All existing std.io readers and writers are deprecated in favor of the newly provided std.Io.Reader and std.Io.Writer which are non-generic and have the buffer above the vtable - in other words the buffer is in the interface, not the implementation. This means that although Reader and Writer are no longer generic, they are still transparent to optimization; all of the interface functions have a concrete hot path operating on the buffer, and only make vtable calls when the buffer is full.

These changes are extremely breaking. I am sorry for that, but I have carefully examined the situation and acquired confidence that this is the direction that Zig needs to go. I hope you will strap in your seatbelt and come along for the ride; it will be worth it.
