New England's last coal-fired power plant "has ceased operations three years ahead of its planned retirement date," reports the New Hampshire Bulletin. "The closure of the New Hampshire facility paves the way for its owner to press ahead with an initiative to transform the site into a clean energy complex including solar panels and battery storage systems." "The end of coal is real, and it is here," said Catherine Corkery, chapter director for Sierra Club New Hampshire. "We're really excited about the next chapter...." The closure in New Hampshire - so far undisputed by the federal government - demonstrates that prolonging operations at some facilities just doesn't make economic sense for their owners. "Coal has been incredibly challenged in the New England market for over adecade," said Dan Dolan, president of the New England Power Generators Association. Merrimack Station, a 438-megawatt power plant, came online in the1960s and provided baseload power to the New England region for decades. Gradually, though, natural gas - which is cheaper and more efficient - took over the regional market... Additionally, solar power production accelerated from 2010 on, lowering demand on the grid during the day and creating more evening peaks. Coal plants take longer to ramp up production than other sources, and are therefore less economical for these shorter bursts of demand, Dolan said. In recent years, Merrimack operated only a few weeks annually. In 2024, the plant generated just0.22% of the region's electricity. It wasn't making enough money to justify continued operations, observers said. The closure "is emblematic of the transition that has been occurring in the generation fleet in New England for many years," Dolan said. "The combination of all those factors has meant that coal facilities are no longer economic in this market." Meanwhile Los Angeles - America's second-largest city - confirmed that the last coal-fired power plant supplying its electricity stopped operations just before Thanksgiving, reports the Utah News Dispatch: Advocates from the Sierra Club highlighted in a news release that shutting down the units had no impact on customers, and questioned who should "shoulder the cost of keeping an obsolete coal facility on standby...." Before ceasing operations, the coal units had been working at low capacities for several years because the agency's users hadn't been calling on the power [said John Ward, spokesperson for Intermountain Power Agency]. The coal-powered units "had a combined capacity of around 1,800 megawatts when fully operational," notes Electrek, "and as recently as 2024, they still supplied around 11% of LA's electricity. The plant sits in Utah's Great Basin region and powered Southern California for decades." Now, for the first time, none of California's power comes from coal. There's a political hiccup with IPP, though: the Republican-controlled Utah Legislature blocked the Intermountain Power Agency from fully retiring the coal units this year, ordering that they can't be disconnected or decommissioned. But despite that mandate, no buyers have stepped forward to keep the outdated coal units online. The Los Angeles Department of Water and Power (LADWP) is transitioning to newly built, hydrogen-capable generating units at the same IPP location, part of a modernization effort called IPP Renewed. These new units currently run on natural gas, but they're designed to burn a blend of natural gas and up to 30% green hydrogen, and eventually100% green hydrogen. LADWP plans to start adding green hydrogen to the fuel mix in 2026. "With the plant now idled but legally required to remain connected, serious questions remain about who will shoulder the cost of keeping an obsolete coal facility on standby," says the Sierra Club. One of the natural gas units started commerical operations last Octoboer, with the second starting later this month, IPP spokesperson John Ward told Agency]. the Utah News Dispatch.

Steven J. Vaughan-Nichols files this report from Tokyo: At the invitation-only Linux Kernel Maintainers Summit here, the top Linux maintainers decided, as Jonathan Corbet, Linux kernel developer, put it, "The consensus among the assembled developers is that Rust in the kernel is no longer experimental - it is now a core part of the kernel and is here to stay. So the 'experimental' tag will be coming off." As Linux kernel maintainer Steven Rosted told me, "There was zero pushback." This has been a long time coming. This shift caps five years of sometimes-fierce debate over whether the memory-safe language belonged alongside C at the heart of the world's most widely deployed open source operating system... It all began when Alex Gaynor and Geoffrey Thomas at the 2019 Linux Security Summit said that about two-thirds of Linux kernel vulnerabilities come from memory safety issues. Rust, in theory, could avoid these by using Rust's inherently safer application programming interfaces (API)... In those early days, the plan was not to rewrite Linux in Rust; it still isn't, but to adopt it selectively where it can provide the most security benefit without destabilizing mature C code. In short, new drivers, subsystems, and helper libraries would be the first targets... Despite the fuss, more and more programs were ported to Rust. By April 2025, the Linux kernel contained about 34 million lines of C code, with only 25 thousand lines written in Rust. At the same time, more and more drivers and higher-level utilities were being written in Rust. For instance, the Debian Linux distro developers announced that going forward, Rust would be a required dependency in its foundational Advanced Package Tool (APT). This change doesn't mean everyone will need to use Rust. C is not going anywhere. Still, as several maintainers told me, they expect to see many more drivers being written in Rust. In particular, Rust looks especially attractive for "leaf" drivers (network, storage, NVMe, etc.), where the Rust-for-Linux bindings expose safe wrappers over kernel C APIs. Nevertheless, for would-be kernel and systems programmers, Rust's new status in Linux hints at a career path that blends deep understanding of C with fluency in Rust's safety guarantees. This combination may define the next generation of low-level development work.

Longtime Slashdot reader AmiMoJo shares a report from Clean Energy Wire: Renewable energy sources covered nearly 56 percent of Germany's gross electricity consumption in 2025, according to preliminary figures by energy industry group BDEW and research institute ZSW. Despite a 'historically weak' first quarter of the year for wind power production and a significant drop in hydropower output, the share of renewables grew by 0.7 percentage points compared to the previous year thanks to an increase in installed solar power capacity. Solar power output increased by 18.7 percent over the whole year, while the strong growth in installed capacity from previous years could be sustained, with more than 17 gigawatts (GW) added to the system. With March being the least windy month in Germany since records began in 1950, wind power output, on the other hand, faced a drop of 5.2 percent compared to 2024. However, stronger winds in the second and third quarter compensated for much of the early-year decrease. Onshore turbines with a capacity of 5.2 GW were added to the grid, a marked increase from the 3.3 GW in the previous year. Due to significantly less precipitation this year compared to 2024, hydropower output dropped by nearly one quarter (24.1%), while remaining only a fraction (3.2%) of total renewable power output.

There's a new Haiku monthly activity report, and this one's a true doozy. Let's start with the biggest news. The most notable development in November was the introduction of a port of the Go programming language, version 1.18. This is still a few years old (from 2022; the current is Go 1.25), but it's far newer than the previous Go port to Haiku (1.4 from 2014); and unlike the previous port which was never in the package repositories, this one is now already available there (for x86_64 at least) and can be installed via pkgman. ↫ Haiku activity report As the project notes, they're still a few versions behind, but at least it's a lot more modern of an implementation than they had before. Now that it's in the repositories for Haiku, it might also attract more people to work on the port, potentially bringing even newer versions to the BeOS-inspired operating system. Welcome as it may be, this new Go port isn't the only big ticket item this month. Haiku can now gracefully recover from an app_server crash, something it used to be able to do a long time ago, but which was broken for a long time. The app_server is Haiku's display server and window manager, so the ability to restart it at runtime after a crash, and have it reconnect with still-running applications, is incredibly welcome. As far as I can tell, all modern operating systems can do this by now, so it's great to have this functionality restored in Haiku. Of course, aside from these two big improvements, there's the usual load of fixes and changes in applications, drivers, and other components of the operating system.

Alpine Linux maintainer Ariadne Conill has published a very interesting blog post about the shortcomings of both sudo and doas, and offers a potential different way of achieving the same goals as those tools. Systems built around identity-based access control tend to rely on ambient authority: policy is centralized and errors in the policy configuration or bugs in the policy engine can allow attackers to make full use of that ambient authority. In the case of a SUID binary like doas or sudo, that means an attacker can obtain root access in the event of a bug or misconfiguration. What if there was a better way? Instead of thinking about privilege escalation as becoming root for a moment, what if it meant being handed a narrowly scoped capability, one with just enough authority to perform a specific action and nothing more? Enter the object-capability model. ↫ Ariadne Conill To bring this approach to life, they created a tool called capsudo. Instead of temporarily changing your identity, capsudo can grant far more fine-grained capabilities that match the exact task you're trying to accomplish. As an example, Conill details mounting and unmounting - with capsudo, you can not only grant the ability for a user to mount and unmount whatever device, but also allow the user to only mount or unmount just one specific device. Another example given is how capsudo can be used to give a service account user to only those resources the account needs to perform its tasks. Of course, Conill explains all of this way better than I ever could, with actual example commands and more details. Conill happens to be the same person who created Wayback, illustrating that they have a tendency to look at problems in a unique and interesting way. I'm not smart enough to determine if this approach makes sense compared to sudo or doas, but the way it's described it does feel like a superior, more secure solution.

Unix has been enormously successful over the past 55 years. It started out as a small experiment to develop a time-sharing system (i.e., a multi-user operating system) at AT&T Bell Labs. The goal was to take a few core principles to their logical conclusion. The OS bundled many small tools that were easy to combine, as it was illustrated by a famous exchange between Donald Knuth and Douglas McIlroy in 1986. Today, Unix lives on mostly as a spiritual predecessor to Linux, Net/Free/OpenBSD, macOS, and arguably, ChromeOS and Android. Usenet tells us about the height of its early popularity. ↫ Gábor Nyéki There are so many amazing stories in this article, I honestly have no idea what to highlight. So first and foremost, I want you to read the whole thing yourself, as everyone's bound to have their own personal favourite section that resonates the most. My personal favourite story from the article - which is just an aside, to illustrate that even the asides are great - is that when Australia joined Usenet in 1983, new posts to Usenet were delivered to the country by airmail. On magnetic tape. Once per week. The overarching theme here is that the early days of UNIX, as documented on Usenet, were a fascinating wild west of implementations, hacks, and personalities, which, yes, clashed with each other, but also spread untold amounts of information, knowledge, and experience to every corner of the world. I hope Nyéki will write more of these articles.

Over the course of 2025, every single major cloud provider has failed. In June, Google Cloud had issues taking down Cloud Storage for many users. In late October, Amazon Web Services had a massive outage in their main hub, us-east-1, affecting many services as well as some people's beds. A little over a week later Microsoft Azure had a [widespread outage][Azure outage] that managed to significantly disrupt train service in the Netherlands, and probably also things that matter. Now last week, Cloudflare takes down large swaths of the internet in a way that causes non-tech people to learn Cloudflare exists. And every single time, people share that one XKCD comic.

After Gandi was bought up and started taking extortion level prices for their domains I've been looking for an excuse to migrate registrar. Last week I decided to bite the bullet and move to Porkbun as I have another domain renewal coming up. However after setting up an account and paying for the transfer for 4 domains, I realized their DNS services are provided by Cloudflare! I personally do not use Cloudflare, and stay far away from all of their products for various reasons.
