Linux Kernel 6.12 Has Been Released
by Peter Reutemann 18 Nov '24

18 Nov '24

'Slashdot unixbhaskar writes: Linus has released a fresh Linux kernel for public consumption. Please give it a try and report any glitches to the maintainers for improvement. Also, please do not forget to express your appreciation to those tireless folks who did all the hard work for you. The blog OMG Ubuntu calls it "one of the most biggest kernel releases for a while," joking that it's a "really real-time kernel." The headline feature in Linux 6.12 is mainline support for PREEMPT_RT. This patch set dramatically improves the performance of real-time applications by making kernel processes pre-emptible — effectively enabled proper real-time computing... Meanwhile, Linus Torvalds himself contributes a new method for user-space address masking designed to claw back some of the performance lost due to Spectre-v1 mitigations. You might have heard that kernel devs have been working to add QR error codes to Linux's kernel panic BSOD screen (as a waterfall of error text is often cut off and not easily copied for ad-hoc debugging). Well, Linux 6.12 adds support for those during Direct Rendering Manager panics... A slew of new RISC-V CPU ISA extensions are supported in Linux 6.12; hybrid CPU scaling in the Intel P-State driver lands ahead of upcoming Intel Core Ultra 2000 chips; and AMD P-State driver improves AMD Boost and AMD Preferred Core features. More coverage from the blog 9to5Linux highlights a new scheduler called sched_ext, Clang support (including LTO) for nolibc, support for NVIDIA's virtual command queue implementation for SMMUv3, and "an updated cpuidle tool that now displays the residency value of cpuidle states for a clearer and more detailed view of idle state information when using cpuidle-info." Linux kernel 6.12 also introduces SWIG bindings for libcpupower to make it easier for developers to write scripts that use and extend the functionality of libcpupower, support for translating normalized error addresses reported by an AMD memory controller into system physical addresses using a UEFI mechanism called platform runtime mechanism (PRM), as well as simplified loading of microcode patches on AMD Zen and newer CPUs by using the family, model, and stepping encoded in the patch revision number... Moreover, Linux 6.12 adds support for running as a protected guest on Android as well as perf and support for a bunch of new interconnect PMUs. It also adds the final conversions to the new Intel VFM CPU model matching macros, rewrites the PCM buffer allocation handling and locking optimizations, and improves the USB audio driver...

mailing list alternatives
by Peter Reutemann 18 Nov '24

18 Nov '24

Hi everyone Here is a list of all the potential options for having the WLUG mailing list continue in some form after the University of Waikato will shut down their mailman instance next month: 1. TechnologyWise would support us and host it at Catalyst (Wellington) Type: unspecified (since general hosting, could be mailman?) Comment: TW ran the BOP LUG that way 2. Linux Australia (https://lists.linux.org.au/mailman/listinfo) Type: mailman (open-source) Comment: not yet contacted whether they'd be open to it 3. Don Gould Type: unspecified (has FLOSS platform, so could be mailman) 4. NZOSS Type: discourse (open-source, at community.iridescent.nz) Comment: unlikely to migrate archives 5. Outlook Groups option Type: MS Outlook (proprietary) Comment: just email distribution, probably no archives In terms of WLUG list archives... I've experimented with hypermail (https://github.com/hypermail-project/hypermail) and was able to turn the 53MB mbox file containing all our posts from the last 25 years into 183MB of HTML. That way, we can at least ensure that the old content doesn't get lost completely. I also talked to Daniel Lawson, who's hosting the old WLUG website and wiki. Though he is not keen on managing mail (bit of a nightmare nowadays according to him), he'd be willing to host the HTML version of the archives. Please reply to this post with your preferred option(s) by Saturday night (e.g., "1" or "1 3 4"). On Sunday, I will then create a final tally (hopefully). Thanks again for your suggestions! Cheers, Peter

New systemd update will bring Windows’ infamous Blue Screen of Death to Linux
by Peter Reutemann 18 Nov '24

18 Nov '24

'Windows' infamous "Blue Screen of Death" is a bit of a punchline. People have made a hobby of spotting them out in the wild, and in some circles, they remain a byword for the supposed flakiness and instability of PCs. To this day, networked PCs in macOS are represented by beige CRT monitors displaying a BSOD. But the BSOD is supposed to be a diagnostic tool, an informational screen that technicians can use to begin homing in on the problem that caused the crash in the first place; that old Windows' BSOD error codes were often so broad and vague as to be useless doesn't make the idea a bad one. Today, version 255 of the Linux systemd project honors that original intent by adding a systemd-bsod component that generates a full-screen display of some error messages when a Linux system crashes. The systemd-bsod component is currently listed as "experimental" and "subject to change." But the functionality is simple: any logged error message that reaches the LOG_EMERG level will be displayed full-screen to allow people to take a photo or write it down. Phoronix reports that, as with BSODs in modern Windows, the Linux version will also generate a QR code to make it easier to look up information on your phone.' -- source: https://arstechnica.com/gadgets/2023/12/linux-distros-are-about-to-get-a-ki… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Debian 12.8 “Bookworm” Released with 68 Bug Fixes and 50 Security Updates
by Peter Reutemann 13 Nov '24

13 Nov '24

'The Debian Project announced today the release and general availability of Debian 12.8 as the seventh ISO update to the latest Debian GNU/Linux 12 “Bookworm” operating system series. Powered by a newer kernel in the Linux 6.1 LTS series, Debian 12.8 is here a little over two months after Debian 12.7 as the seventh point release of Debian Bookworm. Yes, seventh, because Debian 12.3 was never released due to an issue in the EXT4 file system leading to data corruption so it doesn’t count. Debian 12.8 provides those who want to deploy the latest Debian Bookworm operating system on new hardware an up-to-date installation media where they won’t have to download hundreds of updates from the repositories after the installation. In numbers, this new release includes a total of 68 bug fixes for miscellaneous packages and 50 security updates. Details about these security and miscellaneous bug fixes can be found on the release announcement page.' -- source: https://9to5linux.com/debian-12-8-bookworm-released-with-68-bug-fixes-and-5… Cheers, Peter

decommissioning of mailman server
by Peter Reutemann 11 Nov '24

11 Nov '24

Hi everyone Just received word from the university that, as part of their continuing move to proprietary Microsoft services, they are decommissioning their mailman server instance by December 13th and only university-related lists will be moved to an MS service. This, of course, will affect our WLUG mailing list. Any ideas where to go to? Google Groups*? Other free hosting sites for such a low-traffic list? Cheers, Peter * Not sure about import options (posts/members).

GIMP 3.0 Release Candidate Is Now Available for Public Testing
by Peter Reutemann 07 Nov '24

07 Nov '24

'The development team behind the popular GIMP open-source image editing software announced today the general availability of the Release Candidate (RC) milestone of the highly anticipated GIMP 3.0 release. Featuring a much-refined interface, GIMP 3.0 introduces massive improvements to color management, a stable public API to allow porting of plug-ins and scripts from the GIMP 2.10 series, support for loading layers from TIFF files saved in the Autodesk Sketchbook format, and support for 64 bits per pixel images for the BMP format. GIMP 3.0 also promises improvements to non-destructive editing by introducing an optional “Merge Filters” checkbox at the bottom of NDE filters that merges down the filter immediately after it’s committed, along with non-destructive filters on layer groups and the implementation of storing version of filters in GIMP’s XCF project files. “This will allow us to update filters in the future without impacting how older project files look when they’re opened. Additional work will be needed in GEGL to fully implement this feature, but that can be done after 3.0 without impacting existing project files,” said the devs. Among other noteworthy changes, the updated UI of GIMP 3.0 allows the use of the mouse scroll wheel to flip through different dockable dialogue tabs, GEGL and babl components have been updated with new features and many improvements, such as Inner Glow, Bevel, and GEGL Styles filters, and some plugins saw small enhancements. On top of all that, GIMP 3.0 also comes with a new logo, a new splash screen, improvements to the legacy icon theme to look great on HiDPI screens, and the ability to export images with different settings while leaving the original image unchanged.' -- source: https://9to5linux.com/gimp-3-0-release-candidate-is-now-available-for-publi… Cheers, Peter

Linux Mint and Framework Laptops Join Forces
by Peter Reutemann 07 Nov '24

07 Nov '24

'Linux Mint and Framework Laptops Join Forces The October 2024 edition of Linux Mint’s Monthly News brings exciting updates, including a significant announcement about collaboration with Framework Laptops, having potential to advance Mint’s compatibility with hardware designed with flexibility, repairability, and sustainability in mind. For those unfamiliar, unlike most traditional laptops, which are often difficult or impossible to repair or upgrade, Framework laptops are built to be user-friendly, making it easy to replace or upgrade components. This modular approach extends the laptop’s lifespan and promotes sustainability by reducing e-waste. According to Clement Lefebvre, the driving force behind the Linux Mint project, the team recently received Framework’s Laptop 13, and initial impressions are promising. But more importantly, this partnership could open new avenues for Linux Mint, allowing the development team to work with advanced components and technologies featured in Framework’s offerings that haven’t previously been on the project’s radar. Of course, this also means that if compatibility progresses smoothly, Linux Mint could confidently recommend Framework Laptops to its community without hesitation. As Lefebvre noted, the full review of the Laptop 13 will be available in next month’s update, but early sentiments are already positive. Apart from that, the Linux Mint team is currently working on integrating Night Light support into the Cinnamon desktop environment, thus aiming to reduce eye strain for its users. Furthermore, efforts are ongoing to migrate key Cinnamon dialogs to Clutter, enhancing functionality and design. This includes familiar dialogs like the one used to unlock keyrings or confirm display settings.' -- source: https://linuxiac.com/linux-mint-and-framework-laptops-join-forces/ Cheers, Peter
