Linux Kernel 6.12 Confirmed As LTS, Will Be Supported For 'Multiple Years'
by Peter Reutemann 10 Dec '24

10 Dec '24

'Renowned Linux kernel developer Greg Kroah-Hartman announced Thursday that the Linux 6.12 kernel series has been officially marked as LTS (Long Term Support) on the kernel.org website with a predicted life expectancy of at least two years. Linux kernel 6.12 was released on November 17th, 2024, and introduces new features like real-time "PREEMPT_RT" support, a new scheduler called sched_ext, and DRM panic messages as QR codes, as well as numerous new and updated drivers for better hardware support... Linux kernel 6.12 joins the many other long-term support kernel branches, namely Linux 6.6 LTS, Linux 6.1 LTS, Linux 5.15 LTS, Linux 5.10 LTS, and Linux 5.4 LTS. Apart from the latter, the rest of them, including Linux kernel 6.12, will be officially supported until the end of December 2026. Hopefully, Linux kernel 6.12 will be supported for more than two years as the kernel maintainers usually aim for four years of support for a new LTS kernel, especially if there's demand from hardware manufacturers and other companies that aim to use a long-term supported kernel in their devices.

migration of wlug list
by Peter Reutemann 06 Dec '24

06 Dec '24

Hi everyone Thanks to Elliot Hathaway from TechnologyWise working hard behind the scenes, we now have an alternative mailman instance to keep our wlug mailing list going forward. As a reminder, the university server will be shut down next week Friday, December 13th. Thanks to Daniel Lawson, a former WLUG president, and now owner of the wlug.org.nz domain, the list will be a sub-domain under the wlug.org.nz domain. What is next? On Monday, December 9th, we will do a final migration of members and archives from the current mailman instance to the new one. Once that is done, you will receive an invitation to subscribe to the new list. If you want to continue using the list, then please accept it. This might also be a good opportunity to revisit your password and replace it with a strong one (passwords won't be migrated!). I will then make a final post on the old mailing list that the migration has finished with a link to the new one (just in case your invitation ended up in spam). After that, the old mailing list will be disabled, i.e., members removed and no longer accepting new member sign-ups. Have a good weekend!

Linux Making Inroads In PC Gaming
by Lawrence D'Oliveiro 06 Dec '24

06 Dec '24

You’d think that PC gaming was the last nearly unassailable bastion in the Windows world, where potential users who were willing to consider Linux would be few and far between. Reinforcing this idea, Valve tried to bring out its Linux-based “SteamOS” a few years ago, and failed. But then, the Steam Deck pioneered a new market segment, namely PC gaming in a handheld form factor. And here, Valve has found success with Linux -- to the point where the Windows-based competitors look overpriced and underperforming -- in short, just plain clunky. This in spite of the natural advantage of Windows in offering better compatibility with games specifically written for Windows. Now we hear that Valve is having another try at offering SteamOS for third-party hardware <https://arstechnica.com/gaming/2024/12/the-return-of-steam-machines-valve-r…>. The article suggests, and I strongly suspect it is so, that this is to allow those competitors to the Steam Deck to offer a better OS than Windows on their products. Some of them have already made noises to this effect. The Steam Deck is already so far ahead of its Windows-based competitors, that offering serious competition to the Steam Deck will only leave Windows further behind in the lurch -- further cementing the dominance of Linux in this new market segment.

Trying Out Bluesky
by Lawrence D'Oliveiro 04 Dec '24

04 Dec '24

Just signed up at Bluesky <https://bsky.app/> earlier this morning. Did some searches for stuff on Python, Blender, Linux, NZ etc. Already got into reasonably civil discussions with a bunch of people on related topics, and got some likes on my comments. Feels a lot like Twitter from, say, a decade ago. No doubt there are topics with much greater traffic than those I’ve mentioned. Possibly even some loonies and other questionable content, if you look hard enough. This seems to be a Fediverse-type system, connected via open-source protocols/software. I think there are people running their own servers, it’s not all on bluesky.social.

OpenStreetMap Migrates To Debian 12 For Enhanced Performance
by Peter Reutemann 04 Dec '24

04 Dec '24

'OpenStreetMap (OSM), the collaborative project to create a free and open map of the world, has migrated its servers to Debian 12 (Bookworm) after 18 years on Ubuntu. This transition brings with it a number of benefits, including improved speed and closer ties with the Debian community. Why the Switch? The decision to migrate was driven by a number of factors, with performance being a key consideration. OSM's infrastructure relies heavily on physical hardware, and the team encountered significant I/O performance issues with certain kernel versions on systems using NVMe storage. Debian 12 offered a solution by allowing the installation of backported kernels, effectively resolving these performance bottlenecks. Another motivating factor was the desire to align more closely with the maintainers of the software packages that OSM relies on. Debian boasts a strong reputation for package maintenance, and many Debian maintainers are deeply invested in the software they support, ensuring prompt attention to critical bugs. A Smooth Transition The migration process was facilitated by OSM's infrastructure management practices. Their server setup is largely code-driven, and rigorous testing is performed using tools like Test Kitchen and Inspec. By adding Debian as a test target platform, the team was able to identify and address any compatibility issues early on. The required code changes were relatively minor, primarily involving adjustments to package names and configuration filenames. The transition involved the following key steps: - Frontend Server Migration: OSM successfully migrated its frontend servers to Debian 12, resulting in a Ruby version upgrade from 3.0 to 3.1. This upgrade allowed for a corresponding upgrade to the Ruby on Rails framework used for the www.openstreetmap.org website. - Networking Management Shift: OSM transitioned from using netplan, the default network management tool in Ubuntu, to systemd-networkd, Debian's preferred tool. This change streamlined network management across both Ubuntu and Debian systems, ensuring consistency. - Custom Package Management: OSM adopted aptly to manage their own Debian package repository. This shift from Ubuntu's Personal Package Archives (PPA) was driven by the need to manage pre-release or custom patches of OSM software. A Shared Community The move to Debian also reflects the strong overlap between the OSM and Debian communities. Many OSM contributors are also active within the Debian ecosystem, fostering a shared understanding and collaborative spirit.' -- source: https://ostechnix.com/openstreetmap-migrates-to-debian-12-for-enhanced-perf… Cheers, Peter

Code found online exploits LogoFAIL to install Bootkitty Linux backdoor
by Peter Reutemann 02 Dec '24

02 Dec '24

'Researchers have discovered malicious code circulating in the wild that hijacks the earliest stage boot process of Linux devices by exploiting a year-old firmware vulnerability when it remains unpatched on affected models. The critical vulnerability is one of a constellation of exploitable flaws discovered last year and given the name LogoFAIL. These exploits are able to override an industry-standard defense known as Secure Boot and execute malicious firmware early in the boot process. Until now, there were no public indications that LogoFAIL exploits were circulating in the wild. The discovery of code downloaded from an Internet-connected web server changes all that. While there are no indications the public exploit is actively being used, it is reliable and polished enough to be production-ready and could pose a threat in the real world in the coming weeks or months. Both the LogoFAIL vulnerabilities and the exploit found on-line were discovered by Binarly, a firm that helps customers identify and secure vulnerable firmware.' -- source: https://arstechnica.com/security/2024/11/code-found-online-exploits-logofai… Cheers, Peter

GIMP 3.0 - a Milestone For Open-Source Image Editing
by Peter Reutemann 30 Nov '24

30 Nov '24

'The long-awaited release of the GNU Image Manipulation Program (GIMP) 3.0 is on the way, marking the first major update since version 2.10 was released in April 2018. It now features a GTK 3 user interface and GIMP 3.0 introduces significant changes to the core platform and plugins. This release also brings performance and usability improvements, as well as more compatibility with Wayland and complex input sources. GIMP 3.0 is the first release to use GTK 3, a more modern foundation than the GTK 2 base of prior releases. GTK 4 has been available for a few years now, and is on the project's radar, but the plan was always to finish the GTK 3 work first. Moving to GTK 3 brings initial Wayland compatibility and HiDPI scaling. In addition, this allows for GIMP users to take advantage of multi-touch input, bringing pinch-to-zoom gestures to the program, and offering a better experience when working with complex peripherals, such as advanced drawing tablets. These features were not previously possible due to the limitations of GTK 2. A secondary result of the transition to GTK 3 is a refreshed user interface (UI), now with support for CSS themes included. In this release, four themes are available by default, including light, dark, and gray themes, along with a high-contrast theme for users with visual impairments. Additionally, this release has transitioned to using GTK's header bar component, typically used to combine an application's toolbar and title bar into one unit. To maintain familiarity with previous releases, however, GIMP 3.0 still supports the traditional menu interface.' -- source: https://tech.slashdot.org/story/24/11/29/134239/ Cheers, Peter

Both KDE and GNOME To Offer Official Distros
by Peter Reutemann 30 Nov '24

30 Nov '24

'KDE and GNOME have decided that because they're not big and complicated enough already, they might work better if they have their own custom distributions underneath. What's the worst that could happen? A talk from this year's KDE conference, Akademy 2024, looks like it's going to become real. The talk, by KDE developer Harald Sitter, was entitled An Operating System of Our Own, and the idea sounds simple enough: Sitter proposed an official KDE Linux distribution. Now the proposal is gathering steam and a plan is coming together for an official KDE Linux -- codenamed "Project Banana."' -- source: https://tech.slashdot.org/story/24/11/29/2055220 Cheers, Peter
