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 to…

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 hi…

Version 1.95.0 of the Rust language has been released. Changes include the addition of a cfg_select! macro, the capability to use if let guards to allow conditionals based on pattern matching , and many newly stabilized APIs. See the release notes for a full list of changes.

Version 15.0 of the Forgejo code-collaboration platform has been released. Changes include repository-specific access tokens, a number of improvements to Forgejo Actions , user-interface enhancements, and more. Forgejo 15.0 is considered a long-term-support (LTS) release, and will be supported through July 15, 2027. The previous LTS, version 11.0, will reach end of life on July 16, 2026. See the announcement and release notes for a full list of changes.

The 7.1 merge window opened on April 12 with the release of the 7.0 kernel. Since then, 3,855 non-merge changesets have been pulled into the mainline repository for the next release. This merge window is thus just getting started, but there has still been a fair amount of interesting work moving into the mainline.

Version 26.04 of the KDE Gear collection of applications has been released. Notable changes include improvements in the Merkuro Calendar schedule view and event editor, support for threads in the NeoChat Matrix chat client, as well as the ability to add keyboard shortcuts in the Dolphin file manager " to nearly any option in any menu, plugin or extension ". See the changelog for a full list of updates, enhancements, and bug fixes.

OnlyOffice CEO Lev Bannov has recently claimed that the Euro-Office fork of the OnlyOffice suite violates the GNU Affero General Public License version 3 (AGPLv3). Krzysztof Siewicz of the Free Software Foundation (FSF) has published an article on the FSF's position on adding terms to the AGPLv3. In short, the Siewicz concludes that OnlyOffice has added restrictions to the license that are not compatible with the AGPLv3, and those restrictions can be removed by recipients of the code. We urge O…

Many people dislike the proliferation of Large Language Models (LLMs) in recent years, and so make an understandable attempt to avoid them. That may not be possible in general, but there are two new forks of Vim that seek to provide an editing environment with no LLM-generated code. EVi focuses on being a modern Vim without LLM-assisted contributions, while Vim Classic focuses on providing a long-term maintenance version of Vim 8. While both are still in their early phases, the projects look to…

The Zig project has announced version 0.16.0 of the Zig programming language. This release features 8 months of work : changes from 244 different contributors , spread among 1183 commits . Perhaps most notably, this release debuts I/O as an Interface , but don't sleep on the Language Changes or enhancements to the Compiler , Build System , Linker , Fuzzer , and Toolchain which are also included in this release. LWN last covered Zig in December 2025.

Part of the "fun" that comes with curating a self-hosted music library is tagging music so that it has accurate and uniform metadata, such as the band names, album titles, cover images, and so on. This can be a tedious endeavor, but there are quite a few open-source tools to make this process easier. One of the best, or at least my favorite, is MusicBrainz Picard . It is a cross-platform music-tagging application that pulls information from the well-curated, crowdsourced MusicBrainz database pr…

Version 4.0.0 of the OpenSSL cryptographic library has been released. This release includes support for a number of new cryptographic algorithms and has a number of incompatible changes as well; see the announcement for the details.
