As part of my quest to master Emacs, which is sort of a sub-quest on the way toward learning more about Lisp, I have spent a fair amount of time discovering various corners of the Emacs world. One of those is the famous "Org mode" that is used for a wide variety of organizational tasks within the editor—and not just Emacs, but for Vim...

The 4.14.336 stable kernel update has been released with a small handful of fixes; this is the end of the line for the 4.14 stable series: This is the LAST 4.14.y kernel to be released. It is now officially end-of-life. Do NOT use this kernel version anymore, please move to a newer one, as shown on the kernel.org releases page. All users of the...

Security updates have been issued by Fedora (libssh), Gentoo (FAAD2 and RedCloth), Red Hat (kpatch-patch and nss), SUSE (hawk2, LibreOffice, opera, and tar), and Ubuntu (glibc, golang-1.13, golang-1.16, linux-azure, linux-gkeop, monit, and postgresql-9.5).

A new release for any project with a fix for a 12-year old CVE is going to stand out pretty obviously; a recent release has a fix of that nature, but the trail of CVE-2012-5639 is rather elusive. The Apache OpenOffice project made its 4.1.15 release with fixes for four CVEs, including one for CVE-2012-5639 ("Loading internal / external resources without warning"), on December 22. But...

The Vcc compiler has been announced. It’s exactly what the name implies: a clang-based compiler that outputs code that runs on Vulkan. Vcc can be thought of as a GLSL and HLSL competitor, but the true intent of this project is to retire the concept of shading languages entirely. Unlike existing shading languages, Vcc makes a honest attempt to bring the entire C/C++ language...

OpenWrt developer John Crispin says: "In 2024 the OpenWrt project turns 20 years! Let's celebrate this anniversary by launching our own first and fully upstream supported hardware design." The rest of the message describes the proposed OpenWrt-native network-routing system, based Banana Pi boards; the project is being organized through the Software Freedom Conservancy. (Thanks to Dave Täht).

Thorsten Leemhuis writes about his plans for improving the kernel's regression handling in the coming year. Top-priority will be "make regzbot more useful for kernel subsystem maintainers" from now on. My tracking efforts of course will continue, but everything except regressions in the current and the previous mainline cycle might not see much attention from my side. This refocusing also means that I won't...

Anthony Shaw describes the new copy-and-patch JIT that has been proposed for Python 3.13. Copy-and-patch was selected because the compilation from bytecodes to machine code is done as a set of “templates” that are then stitched together and patched at runtime with the correct values. This means that your average Python user isn’t running this complex JIT compiler architecture inside their Python runtime. Python...

Version 4.5 ("Resilience") of the Solus distribution has been released. "This release brings updated applications and kernels, refreshed software stacks, a new installer, and a new ISO edition featuring the XFCE desktop environment."

Security updates have been issued by Debian (squid), Fedora (podman), Mageia (dropbear), SUSE (eclipse-jgit, jsch, gcc13, helm3, opusfile, qt6-base, thunderbird, and wireshark), and Ubuntu (clamav, libclamunrar, and qemu).

The 6.7 kernel was released on January 7 after a ten-week development cycle. This was, as it turns out, the busiest cycle ever with regard to the number of changesets merged. The time has come for our usual look at where all those changesets came from, with a side trip into how long kernel developers tend to stick around.

Greg Kroah-Hartman has announced the release of the 5.4.266, 4.19.304, and 4.14.335 stable kernels. They contain important fixes throughout the kernel tree.

Security updates have been issued by Debian (exim4), Fedora (chromium, perl-Spreadsheet-ParseExcel, python-aiohttp, python-pysqueezebox, and tinyxml), Gentoo (Apache Batik, Eclipse Mosquitto, firefox, R, Synapse, and util-linux), Mageia (libssh2 and putty), Red Hat (squid), SUSE (libxkbcommon), and Ubuntu (gnutls28).

Linus has released the 6.7 kernel. End result: 6.7 is (in number of commits: over 17k non-merge commits, with 1k+ merges) one of the largest kernel releases we've ever had, but the extra rc8 week was purely due to timing with the holidays, not about any difficulties with the larger release. Some of the headline features in this release are: the removal of support...

Kernel developers often go out of their way to reduce the memory used by the kernel itself; that memory is not available for the workloads that people are actually interested in running on their systems. Lower memory usage also tends to lead to better performance overall. But there are times when the expenditure of some extra memory can make the system faster. The replication...

The 6.6.10, 6.1.71, 5.15.146, and 5.10.206 stable kernels have been released. They contain numerous important fixes, as usual.

Security updates have been issued by Debian (asterisk, chromium, exim4, netatalk, and tomcat9), Fedora (chromium), Gentoo (BlueZ, c-ares, CUPS filters, RDoc, and WebKitGTK+), Oracle (firefox, squid:4, thunderbird, and tigervnc), SUSE (python-aiohttp and python-paramiko), and Ubuntu (linux-intel-iotg).

The saga of the None-aware (or null-coalescing) operators for Python continues. We last looked in on the topic a little over a year ago and noted that either adoption or a clear rejection of the idea might help tamp down its regular recurrence. That has not happened, so, predictably, it was raised again—and does not look any closer to resolution this time around.

ITWire covers the passing of Niklaus Wirth. Wirth is well-remembered for his pioneering work in programming languages and algorithms. For these achievements, he received the ACM Turing Award in 1984, inducted as a Fellow of the ACM in 1994, and a Fellow of the Computer History Museum in 2004. They include, among many, being chief designer for the programming languages Euler (1965), PL360 (1966),...

Security updates have been issued by Oracle (firefox, gstreamer1-plugins-bad-free, thunderbird, tigervnc, and xorg-x11-server), Red Hat (squid:4), SUSE (exim, libcryptopp, and proftpd), and Ubuntu (openssh and sqlite3).

Normally, when a new vulnerability is discovered and releases are coordinated with those affected, the announcement is done at a convenient time—not generally right before the end-of-year holidays, for example. The SMTP Smuggling vulnerability has taken a different path, however, with its announcement landing on December 18. That may well have been unpleasant for some administrators that had not yet updated, but it was particularly...

On his blog, Luc Lenôtre introduces Maestro, "a Unix-like kernel and operating system written from scratch in Rust". Maestro is intended to be "lightweight and compatible-enough with Linux to be usable in everyday life". The project began, in C, back in 2018, but switched over to Rust after a year-and-a-half. The current status: Maestro is a monolithic kernel, supporting only the x86 (in 32...

Version 9.1 of the Vim editor has been released. "This release is dedicated to Bram Moolenaar, Vim's lead developer for more than 30 years, who passed away half a year ago. The Vim project wouldn't exist without his work". Changes include new support for classes and objects in the scripting language, smooth scrolling support, an EditorConfig plugin, and more.
