The first stable release of the Thunderbird mail client for Android is now available: Just over two years ago, we announced our plans to bring Thunderbird to Android by taking K-9 Mail under our wing. The journey took a little longer than we had originally anticipated and there was a lot to learn along the way, but the wait is finally over! For all...

Security updates have been issued by AlmaLinux (buildah), Debian (python-git, texlive-bin, and xorg-server), Mageia (chromium-browser-stable), Red Hat (kernel), SUSE (Botan, go1.22-openssl, go1.23-openssl, grafana, libgsf, pcp, pgadmin4, python310-pytest-html, python313, xorg-x11-server, and xwayland), and Ubuntu (nano, python-urllib3, and xorg-server, xwayland).

Mozilla has announced the release of a new version of Firefox. This version has the usual mix of security fixes and new features, as well as a handful of deprecations. The release removes support for HTTP/2 Push, but adds hardware acceleration for SVGs, support for wide color gamuts on more platforms, and restores support for remote debugging via USB.

Fedora Linux 41 has been released. See the "what's new" pages for Fedora Workstation and Fedora KDE, to learn more about the latest in those editions. There is also a new Fedora Miracle Window Manager Spin that offers the Miracle tiling window manager for Wayland.

The first program that Martin Pool ever wrote, he said, had bugs; the ones he's writing now most likely have bugs too. The talk Pool gave at RustConf this year was about a way to try to write programs with fewer bugs. He has developed a tool called cargo-mutants that highlights gaps in test coverage by identifying functions that can be broken without causing...

A project called Flock has announced its existence. Flock is a fork of the Flutter user-interface toolkit project, motivated by frustration with the resources that Google is putting into Flutter. We describe Flock as "Flutter+". In other words, we do not want, or intend, to fork the Flutter community. Flock will remain constantly up to date with Flutter. Flock will add important bug fixes,...

Debian Developer Russell Coker has written up an analysis of the remote exploit of CUPS announced in September: He seems to have a different experience to me of reporting bugs, I have had plenty of success getting bugs fixed without hyping them. I just report the bug, wait a while, and it gets fixed. [...] I was quite confident that my systems wouldn't be...

The Open Source Initiative (OSI) has announced the release of version 1.0 of the Open Source AI Definition: The OSAID offers a standard by which community-led, open and public evaluations will be conducted to validate whether or not an AI system can be deemed Open Source AI. This first stable version of the OSAID is the result of multiple years of research and collaboration,...

Sparrow Li presented virtually at RustConf 2024 about the current state of and future plans for the Rust compiler's performance. The compiler is relatively slow to compile large programs, although it has been getting better over time. The next big performance improvement to come will be parallelizing the compiler's parsing, type-checking, and related operations, but even after that, the project has several avenues left to...

Rong Xu and Han Shen described the kernel-optimization techniques that Google uses in the toolchains track at the 2024 Linux Plumbers Conference. They talked about automatic feedback-directed optimization (AutoFDO), which can be used with the Propeller optimizer to produce kernels with better performance using profile information gathered from real workloads. There is a fair amount of overlap between these tools and the BOLT post-link...

Security updates have been issued by AlmaLinux (kernel, python3.12, and python3.9), Debian (activemq, chromium, libheif, nss, and twisted), Fedora (chromium, dnsdist, dotnet8.0, edk2, glibc, libdigidocpp, mbedtls3.6, NetworkManager-libreswan, oath-toolkit, podman-tui, prometheus-podman-exporter, python-fastapi, python-openapi-core, python-platformio, python-rpyc, python-starlette, rust-pyo3, rust-pyo3-build-config, rust-pyo3-ffi, rust-pyo3-macros, rust-pyo3-macros-backend, suricata, thunderbird, and yarnpkg), Mageia (cpanminus, libgsf, mozjs78, redis, and thunderbird), Oracle (firefox, python3.12, python3.9, and python39:3.9 and python39-devel:3.9), Red Hat (edk2, grafana, httpd,...

Linus has released 6.12-rc5 for testing. rc5 looks perfectly normal, and maybe even on the small side of normal. The diffstat looks nice and flat too, with the exception of the removal of the da8xx fbdev driver due to it having been replaced by the tilcdc driver. And I'm sure we're all thinking the same thing: "What lovely descriptive driver names we have".

The Open Source Initiative (OSI) has been working on defining Open Source AI—that is what constitutes an AI system that can be used, studied, modified, and shared for any purpose—for almost two years. Its board will be voting on the Open Source AI Definition (OSAID) on Sunday, October 27, with the 1.0 version slated to be published on October 28. It is never possible to please...

A pair of talks in the toolchains track at the 2024 Linux Plumbers Conference covered different tools that can be used to optimize the kernel. First up was Maksim Panchenko to describe the binary optimization and layout tool (BOLT) that Meta uses on its production kernels. It optimizes the kernel binary by rearranging it to improve its code locality for better performance. A subsequent...

Security updates have been issued by Debian (distro-info-data), Fedora (libtiff), Mageia (firefox and oath-toolkit), Red Hat (krb5), and SUSE (openssl-1_1).

Small objects can lead to large email threads. In this case, the GNU C Library (glibc) community has been having an extensive debate over the handling of zero-byte allocations. Specifically, what should happen when a program calls realloc() specifying a size of zero? This is, it seems, a topic about which some people, at least, have strong feelings.

Security updates have been issued by AlmaLinux (grafana, NetworkManager-libreswan, python3.11, and python39:3.9 and python39-devel:3.9), Fedora (dotnet6.0, koji, python-fastapi, python-openapi-core, python-platformio, python-starlette, rust-pyo3, rust-pyo3-build-config, rust-pyo3-ffi, rust-pyo3-macros, rust-pyo3-macros-backend, and yarnpkg), Oracle (grafana, kernel, linux-firmware, NetworkManager-libreswan, and python3.11), Slackware (php81), and SUSE (apache2, buildah, cups-filters, go1.21-openssl, podman, postgresql16, python-pyOpenSSL, and webkit2gtk3).

Currently in Rust, there is no efficient and safe way to turn an array of bytes into a structure that corresponds to the array. Changing that was the topic of Jack Wrenn's talk this year at RustConf: "Safety Goggles for Alchemists". The goal is to be able to "transmute" — Rust's name for this kind of conversion — values into arbitrary user-defined types in...

Version 14.0 of the privacy-focused Tor browser has been released. This is our first stable release based on Firefox ESR 128, incorporating a year's worth of changes shipped upstream in Firefox. As part of this process we've also completed our annual ESR transition audit, where we reviewed and addressed over 200 Bugzilla issues for changes in Firefox that may negatively affect the privacy and...

Jakub Kadlčík announced on his blog that Fedora's Copr build system will be dropping support for building modules (groups of RPM packages that are built, installed, and shipped together) soon: The Fedora Modularity project never really took off, and building modules in Copr even less so. We've had only 14 builds in the last two years. It's not feasible to maintain the code for...

In July, at the GNOME annual general meeting (AGM), held at GUADEC 2024, the message from the GNOME Foundation board was that all was well, financially speaking. Not great, but the foundation was on a break-even budget and expected to go into its next fiscal year with a similar budget and headcount. On October 7, however, the board announced that it had had to make...

Security updates have been issued by Debian (dmitry, libheif, and python-sql), Fedora (suricata and wireshark), SUSE (cargo-c, libeverest, protobuf, and qemu), and Ubuntu (golang-1.22, libheif, unbound, and webkit2gtk).
