Could New Linux Code Cut Data Center Energy Use By 30%?
by Peter Reutemann 26 Jan '25

26 Jan '25

'Two computer scientists at the University of Waterloo in Canada believe changing 30 lines of code in Linux "could cut energy use at some data centers by up to 30 percent," according to the site Data Centre Dynamics. It's the code that processes packets of network traffic, and Linux "is the most widely used OS for data center servers," according to the article: The team tested their solution's effectiveness and submitted it to Linux for consideration, and the code was published this month as part of Linux's newest kernel, release version 6.13. "All these big companies — Amazon, Google, Meta — use Linux in some capacity, but they're very picky about how they decide to use it," said Martin Karsten [professor of Computer Science in the Waterloo's Math Faculty]. "If they choose to 'switch on' our method in their data centers, it could save gigawatt hours of energy worldwide. Almost every single service request that happens on the Internet could be positively affected by this." The University of Waterloo is building a green computer server room as part of its new mathematics building, and Karsten believes sustainability research must be a priority for computer scientists. "We all have a part to play in building a greener future," he said. The Linux Foundation, which oversees the development of the Linux OS, is a founder member of the Green Software Foundation, an organization set up to look at ways of developing "green software" — code that reduces energy consumption. Karsten "teamed up with Joe Damato, distinguished engineer at Fastly" to develop the 30 lines of code, according to an announcement from the university. "The Linux kernel code addition developed by Karsten and Damato was based on research published in ACM SIGMETRICS Performance Evaluation Review" (by Karsten and grad student Peter Cai). Their paper "reviews the performance characteristics of network stack processing for communication-heavy server applications," devising an "indirect methodology" to "identify and quantify the direct and indirect costs of asynchronous hardware interrupt requests (IRQ) as a major source of overhead... "Based on these findings, a small modification of a vanilla Linux system is devised that improves the efficiency and performance of traditional kernel-based networking significantly, resulting in up to 45% increased throughput..."' -- source: https://hardware.slashdot.org/story/25/01/25/2111225 Cheers, Peter

Wine 10.0 brings Arm Windows apps to Linux, still is not an emulator
by Peter Reutemann 23 Jan '25

23 Jan '25

'The open source Wine project—sometimes stylized WINE, for Wine Is Not an Emulator—has become an important tool for companies and individuals who want to make Windows apps and games run on operating systems like Linux or even macOS. The CrossOver software for Mac and Windows, Apple's Game Porting Toolkit, and the Proton project that powers Valve's SteamOS and the Steam Deck are all rooted in Wine, and the attention and resources put into the project in recent years have dramatically improved its compatibility and usefulness. Yesterday, the Wine project announced the stable release of version 10.0, the next major version of the compatibility layer that is not an emulator. The headliner for this release is support for ARM64EC, the application binary interface (ABI) used for Arm apps in Windows 11, but the release notes say that the release contains "over 6,000 individual changes" produced over "a year of development effort." ARM64EC allows developers to mix Arm and x86-compatible code—if you're making an Arm-native version of your app, you can still allow the use of more obscure x86-based plugins or add-ons without having to port everything over at once. Wine 10.0 also supports ARM64X, a different type of application binary file that allows ARM64EC code to be mixed with older, pre-Windows 11 ARM64 code. Wine's ARM64EC support does have one limitation that will keep it from working on some prominent Arm Linux distributions, at least by default: the release notes say it "requires the system page size to be 4K, since that is what the Windows ABI specifies." Several prominent Linux-on-Arm distributions default to a 16K page size because it can improve performance—when page sizes are smaller, you need more of them, and managing a higher number of pages can introduce extra CPU overhead.' -- source: https://arstechnica.com/gadgets/2025/01/wine-10-0-released-adding-linux-com… Cheers, Peter

TuxCare Stops Microsoft From Killing .NET 6.0
by Peter Reutemann 17 Jan '25

17 Jan '25

'TuxCare today announced that it’s added Microsoft’s .NET 6.0 to the roster of open-source platforms its supporting through its Endless Lifecycle Support program. This means that organizations that wish to continue using the platform, which reached end of life on Nov 12, 2024 and no longer receives updates, can continue to safely do so. TuxCare’s service will supply security patches for any vulnerabilities that arise in the software, just as it continues to patch long dead Linux distros. In times past, continuing to keep expired software in production was considered to be bad policy. These days, however, it’s becoming more common for sysadmins and DevOps teams to rely on services like TuxCare rather than go through the often frustrating and always time consuming and costly ordeal of upgrading, a process that often breaks essential secondary components which then have to be upgraded or fixed. When FOSS Force spoke with Joao Correia, a technical evangelist for both TuxCare and its parent company CloudLinux, he was quick to point out that supporting a product from Microsoft is something new, not only for TuxCare but for any of the companies that offer aftermarket support for expired open-source projects. “That’s somewhat of a departure in that we are now touching on proprietary Microsoft space which we hadn’t touched before,” he said. “At the same time, it’s an open-source project, and we have lots of experience with those types of projects and maintaining them.”' -- source: https://fossforce.com/2025/01/tuxcare-stops-microsoft-from-killing-net-6-0/ Cheers, Peter

Debian 12.9 “Bookworm” Arrives with 72 Bug Fixes and 38 Security Updates
by Peter Reutemann 14 Jan '25

14 Jan '25

'Today, the Debian Project announced the release and general availability of Debian 12.9 as the eighth ISO update to the latest Debian GNU/Linux 12 “Bookworm” operating system series. Coming a little over two months after Debian 12.8 and powered the Linux 6.1 LTS series, Debian 12.9 is the eighth point release of Debian Bookworm. Yes, eighth, 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. As with previous updates, Debian 12.9 is here to provide updated installation media to those who want to deploy the latest Debian Bookworm operating system on new hardware and they had issues with previous Debian 12 versions or don’t want to download hundreds of updates from the repositories after the installation. In numbers, this new release includes a total of 72 bug fixes for miscellaneous packages and 38 security updates. Details about these security and miscellaneous bug fixes can be found on the release announcement page.' -- source: https://9to5linux.com/debian-12-9-bookworm-arrives-with-72-bug-fixes-and-38… -- release: https://www.debian.org/News/2025/20250111 Cheers, Peter

Mastodon’s founder cedes control, refuses to become next Musk or Zuckerberg
by Peter Reutemann 14 Jan '25

14 Jan '25

'Mastodon announced Monday that it's shifting its structure over the next six months to become wholly owned by a European nonprofit organization—"affirming the intent that Mastodon should not be owned or controlled by a single individual." This takes control of the social network away from its previous "ultimate decision-maker," Eugen Rochko. As founder, Rochko initially took the reins to ensure the decentralized platform would never be for sale and "would be free of the control of a single wealthy individual." His grand vision remains to leave Mastodon users in control of the social network, making their own decisions about what content is allowed or what appears in their timelines. The news comes after leaders of other social networks, like Mark Zuckerberg and Elon Musk, have sparked backlash over sudden changes to popular apps like Facebook, Instagram, and X (formerly Twitter). For years, Musk has drawn criticism for changing Twitter's hate speech policies through his X rebranding. And more recently, Zuckerberg this month defended Meta's decision to relax hate speech policies (permitting women to be called "property" and gay people to be called "mentally ill") by calling bans on such speech "out of touch with mainstream discourse." Mastodon is hoping to provide an alternative social network for users who are potentially frustrated with their lack of control over their timelines and content on other networks. But to achieve the "envisioned independence" for all users, Mastodon's structure needed to "evolve," the blog said, "as the community grew" to about 1.5 million monthly active users in 2023. Remaining headquartered in Europe primarily, Mastodon's day-to-day operations will be managed by the new European not-for-profit entity, "establishing a new legal home for Mastodon." The user experience on Mastodon won't be affected much by the transition to a nonprofit owner, Mastodon said. But "changes are definitely in the pipeline."' -- source: https://arstechnica.com/tech-policy/2025/01/mastodon-becomes-nonprofit-to-m… Cheers, Peter

German router maker is latest company to inadvertently clarify the LGPL license
by Peter Reutemann 13 Jan '25

13 Jan '25

'The GNU General Public License (GPL) and its "Lesser" version (LGPL) are widely known and used. Still, every so often, a networking hardware maker has to get sued to make sure everyone knows how it works. The latest such router company to face legal repercussions is AVM, the Berlin-based maker of the most popular home networking products in Germany. Sebastian Steck, a German software developer, bought an AVM Fritz!Box 4020 (PDF) and, being a certain type, requested the source code that had been used to generate certain versions of the firmware on it. According to Steck's complaint (translated to English and provided in PDF by the Software Freedom Conservancy, or SFC), he needed this code to recompile a networking library and add some logging to "determine which programs on the Fritz!Box establish connections to servers on the Internet and which data they send." But Steck was also concerned about AVM's adherence to GPL 2.0 and LGPL 2.1 licenses, under which its FRITZ!OS and various libraries were licensed. The SFC states that it provided a grant to Steck to pursue the matter. AVM provided source code, but it was incomplete, as "the scripts for compilation and installation were missing," according to Steck's complaint. This included makefiles and details on environment variables, like "KERNEL_LAYOUT," necessary for compilation. Steck notified AVM, AVM did not respond, and Steck sought legal assistance, ultimately including the SFC. Months later, according to the SFC, AVM provided all the relevant source code and scripts, but the suit continued. AVM ultimately paid Steck's attorney fee. The case proved, once again, that not only are source code requirements real, but the LGPL also demands freedom, despite its "Lesser" name, and that source code needs to be useful in making real changes to firmware—in German courts, at least. "The favorable result of this lawsuit exemplifies the power of copyleft—granting users the freedom to modify, repair, and secure the software on their own devices," the SFC said in a press release. "Companies like AVM receive these immense benefits themselves. This lawsuit reminded AVM that downstream users must receive those very same rights under copyleft."' -- source: https://arstechnica.com/gadgets/2025/01/suing-wi-fi-router-makers-remains-a… Cheers, Peter

Linux Foundation bands together Chromium browser makers in a “neutral space”
by Peter Reutemann 10 Jan '25

10 Jan '25

'Supporters of Chromium-Based Browsers sounds like a very niche local meetup, one with hats and T-shirts that barely fit the name. But it's really a "neutral space" for funding and support, corralling together some big names with a stake in the future of Chrome's open source roots, Chromium. The Linux Foundation, a nonprofit started in 2000 that has grown to support a broader range of open source projects, spurred the initiative. In a press release, the Foundation states that the project will allow "industry leaders, academia, developers, and the broader open source community" to work on Chromium, with "much-needed funding and development support for open development of projects." A few names you don't often see together are already on board: Google, Meta, Microsoft, and Opera. Krystian Kolondra, executive vice president of browsers at Opera, stated in a release that "as one of the major browsers contributing to the Chromium project," Opera would "look forward to collaborating with members of the project to foster this growth and keep building innovative and compelling products for all users." How will this work? Kind of how Chromium has been working already. The group will have an open governance model, according to the Foundation, based on other Foundation initiatives based on "transparency, inclusivity, and community-driven development." The Linux Foundation's structure supports Kubernetes, Node.js, RISC-V, ONAP, and, of course, Linux, in such a manner. A Technical Advisory Committee will ensure the work done in the group "meets the needs of the wider Chromium community." Otherwise, the Chromium projects will keep to their existing governance structures.' -- source: https://arstechnica.com/gadgets/2025/01/google-meta-microsoft-and-opera-agr… Cheers, Peter
