Joplin is an open-source note-taking application designed to handle taking many kinds of notes, whether it is managing code snippets, writing documentation, jotting down lecture notes, or drafting a novel. Joplin has Markdown support, a plugin system for extensibility, and accepts multimedia content, allowing users to attach images, videos, and audio files to their notes. It can provide synchronization of content across devices using end-to-end encryption, or users can opt to stick to local storage only. Joplin even offers a command-line version for terminal-based usage. Joplin 3.2, the most recent feature release, brought long-awaited multi-window support, multi-column layouts, enhanced accessibility, and theme detection.

Quite a bit of work has been done in recent years to allow the kernel to make more use of large folios. That progress has not yet reached the handling of text (executable code) areas, though. During the memory-management track of the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit, Ryan Roberts ran a session on how that situation might be improved. It would be a relatively small and contained operation, but can give a measurable performance improvement.

The kernel makes extensive use of per-CPU data as a way to avoid contention between processors and improve scalability. Using the same technique in user space is harder, though, since there is little control over which CPU a process may be running on at any given time. That hasn't stopped Mathieu Desnoyers from trying, though; in the memory-management track of the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit, he presented a proposal for how user-space per-CPU memory could work.

Security updates have been issued by AlmaLinux (gimp, libxslt, python3.11, python3.12, and tomcat), Debian (ghostscript and libnet-easytcp-perl), Fedora (openvpn, perl-Data-Entropy, and webkitgtk), Red Hat (python-jinja2), SUSE (giflib, pam, and xen), and Ubuntu (apache2, binutils, expat, fis-gtm, linux-azure, linux-azure-6.8, linux-nvidia-lowlatency, linux-azure, linux-azure-fde, linux-azure-5.15, linux-azure-fde-5.15, linux-azure-fips, linux-gcp-fips, linux-hwe-5.4, linux-nvidia, linux-nvidia-tegra-igx, ruby2.7, ruby3.0, ruby3.2, ruby3.3, and vim).

In this post, we explain the HTTP 422 Error Unprocessable Content. What is it, and how can you fix it? The HTTP 422 Error belongs to the 4xx status codes and is a client-side error. It indicates that the server understood the request content, the syntax was okay, but its instructions could not be processed. This error appears in particular cases involving API interactions, so it is not a standard HTTP 4xx error.

In the following paragraphs, we will explain this error, teach you how to troubleshoot it, and how to fix it. Let’s get started!

Pahole (originally "Poke-a-hole") is a Swiss Army knife for exploring and editing debug information. Pahole is also currently involved in the kernel's build process to rearrange the information produced by various compilers into a form useful to the BPF verifier, although there are plans to render it unnecessary. Pahole maintainer Arnaldo Carvalho de Melo shared some status updates about the project at the 2025 Linux Storage, Filesystem, Memory-Management, and BPF summit. Interested readers can find his slides here.

ACM Queue looks at the security problem in the light of a report on Multics security that was published in 1974.

We are all struggling with a massive shift that has happened in the past 10 or 20 years in the software industry. For decades, software reuse was only a lofty goal. Now it's very real. Modern programming environments such as Go, Node, and Rust have made it trivial to reuse work by others, but our instincts about responsible behaviors have not yet adapted to this new reality.

The fact that the 1974 Multics review anticipated many of the problems we face today is evidence that these problems are fundamental and have no easy answers. We must work to make continuous improvements to open source software supply chain security, making attacks more and more difficult and expensive.

The kernel's swap subsystem is complex and highly optimized — though not always optimized for today's workloads. In three adjacent sessions during the memory-management track of the 2025 Linux Storage, Filesystem, Memory-Management, and BPF Summit, Kairui Song, Nhat Pham, and Usama Arif all talked about some of the problems that they are trying to solve in the Linux swap subsystem. In the first two cases, the solutions take the form of an additional layer of indirection in the kernel's swap map; the third, which enables swap-in of large folios, may or may not be worthwhile in the end.

Linus Torvalds released 6.15-rc1 and closed the 6.15 merge window on April 6. By that time, 12,633 non-merge changesets had found their way into his repository; that is substantially more than were merged during the entire 6.14 development cycle. Just under 6,000 of those changesets were merged after the first-half merge-window summary was written.

The 6.14.1, 6.13.10, 6.12.22, 6.6.86, and 6.1.133 stable kernels have all been released. They contain a relatively small collection of important fixes across the kernel tree.
