Version 2.0 of the Aqualung gapless music player has been released. Aqualung supports playback of a wide range of audio formats, ripping CDs to WAV, FLAC, Ogg Vorbis, or MP3, and subscribing to podcasts via RSS or Atom feeds. The primary change in this release is the...
The kernel's slab allocator is responsible for the allocation of small (usually sub-page) chunks of memory. For many workloads, the speed of object allocation and freeing is one of the key factors in overall performance, so it is not surprising that a lot of effort has gone...
The AlmaLinux project has published a request for comments (RFC) on rebuilding Fedora's Extra Packages for Enterprise Linux (EPEL), which provides additional software for Red Hat Enterprise Linux (RHEL) and its derivatives, to support older x86_64 hardware that is not...
The Emacs extensible text editor (among other things) has made a security release to address two vulnerabilities. Emacs 30.1 has fixes for CVE-2025-1244, which is a shell-command-injection flaw in the man.el man page browser and for CVE-2024-53920, which is a code-execution...

The 6.14-rc4 kernel prepatch is out for testing. 'This continues to be the right kind of 'boring' release: nothing in particular stands out in rc4'.

The pytest-mh project is a plugin that provides a multi-host test framework for the popular pytest unit-testing framework and test runner. Work on pytest-mh started in 2023 to solve a multitude of issues that cropped up for developers and testers when testing the SSSD...

At the end of January we ran this article on the discussions around a set of Rust bindings for the kernel's DMA-mapping layer. Many pixels have been expended on the topic since across the net, most recently in this sprawling email thread. Linus Torvalds has now made his...

Version 1.85.0 of the Rust language has been released. Changes in the release include support for async closures, some convenience iterators for tuples, and a number of stabilized APIs. The headline feature, though, is that this release stabilizes the Rust 2024 edition,...
The maximum filesystem block size that the kernel can support has always been limited by the host page size for Linux, even if the filesystems could handle larger block sizes. The large-block-size (LBS) patches that were merged for the 6.12 kernel removed this limitation in...
Atomic block writes, which have been discussed here a few times in the past, are block operations that either complete fully or do not occur at all, ensuring data consistency and preventing partial (or 'torn') writes. This means the disk will, at all times, contain either...

Steven Rostedt recently posted a patch set that could help improve the performance of certain user-space applications by giving the scheduler more context about when they are safe to interrupt. The patch set lets programs request a small grace window before they can be...
