Recently, I had a learning experience with cron jobs and acme.sh. acme.sh is an excellent tool that simplifies the management of Let's Encrypt TLS (SSL) certificates. It makes obtaining and renewing these essential security certificates for your web server easier. Recently, I moved my server from Linode to AWS, which was a new environment for me. Initially, everything appeared to be working correctly, and I assumed everything was running smoothly. However, I forgot to migrate the cron job that acme.sh uses to renew the certificate automatically. This oversight caused my Let's Encrypt certificates to expire, resulting in security warnings and potential disruptions for visitors to my website. Opps!

You can find the timezone in Linux using the command line. The easiest way to do this is to type the "timedatectl" command and look for the "timezone" line when using modern Linux distros with systemd. There are other commands and ways to temporarily switch to a new timezone for date calculations.

In July Google promised to scale the CO2 batteries of "Energy Dome" as a long-duration energy storage solution. Now IEEE Spectrum visits its first plant in Sardinia, where 2,000 tonnes of carbon dioxide power a turbine generating 20 MW over 10 hours — storing "large amounts of excess renewable energy until it's needed..." "Google likes the concept so much that it plans to rapidly deploy the facilities in all of its key data-center locations in Europe, the United States, and the Asia-Pacific region." Developed by the Milan-based company Energy Dome, the bubble and its surrounding machinery demonstrate a first-of-its-kind "CO2 Battery," as the company calls it... And in 2026, replicas of this plant will start popping up across the globe. We mean that literally. It takes just half a day to inflate the bubble. The rest of the facility takes less than two years to build and can be done just about anywhere there's 5 hectares of flat land. The first to build one outside of Sardinia will be one of India's largest power companies, NTPC Limited. The company expects to complete its CO2 Battery sometime in 2026 at the Kudgi power plant in Karnataka, in India. In Wisconsin, meanwhile, the public utility Alliant Energy received the all clear from authorities to begin construction of one in 2026 to supply power to 18,000 homes... The idea is to provide electricity-guzzling data centers with round-the-clock clean energy, even when the sun isn't shining or the wind isn't blowing. The partnership with Energy Dome, announced in July, marked Google's first investment in long-duration energy storage... CO2 Batteries check a lot of boxes that other approaches don't. They don't need special topography like pumped-hydro reservoirs do. They don't need critical minerals like electrochemical and other batteries do. They use components for which supply chains already exist. Their expected lifetime stretches nearly three times as long as lithium-ion batteries. And adding size and storage capacity to them significantly decreases cost per kilowatt-hour. Energy Dome expects its LDES solution to be 30 percent cheaper than lithium-ion. China has taken note. China Huadian Corp. and Dongfang Electric Corp. are reportedly building a CO2-based energy-storage facility in the Xinjiang region of northwest China. Google's senior lead for energy storage says they like how Energy Dome's solution can work in any region. "They can really plug and play this." And they expect Google to help the technology "reach a massive commercial stage."

9to5Linux Weekly Roundup: December 21st, 2025  9to5Linux

Linux 6.19-rc2 Released Following A Quiet Week  Phoronix

Long-time Slashdot reader destinyland wonders if "gifts for geeks" is the next big consumer demographic: For this year's holiday celebrations, Hallmark made a special Christmas tree ornament, a tiny monitor displaying screens from the classic video game "Oregon Trail." ("Recall the fun of leading a team of oxen and a wagon loaded with provisions from Missouri to the West....") Top sites and major brands are now targeting the "tech" demographic — including programmers, sysadmins and even vintage game enthusiasts — and when Hallmark and Amazon are chasing the same customers as GitHub and Copilot, you know there's been a strange yet meaningful shift in the culture... While AI was conquering the world, GitHub published its "Ultimate gift guide for the developer in your life" just as soon as doors opened on Black Friday. So if you're wondering, "Should I push to production on New Year's Eve?" GitHub recommends their new "GitHub Copilot Amazeball," which it describes as "GitHub's magical collectible ready to weigh in on your toughest calls !" Copilot isn't involved — questions are randomly matched to the answers printed on the side of a triangle-shaped die floating in water. "[Y]ou'll get answers straight from the repo of destiny with a simple shake," GitHub promises — just like the Magic 8 Ball of yore. "Get your hands on this must-have collectible and enjoy the cosmic guidance — no real context switching required!" And GitHub's "Gift Guide for Developers" also suggests GitHub-branded ugly holiday socks and keyboard keycaps with GitHub's mascots. But GitHub isn't the only major tech site with a shopping page targeting the geek demographic. Firefox is selling merchandise with its new mascot. Even the Free Software Foundation has its own shop, with Emacs T-shirts, GNU beanies and a stuffed baby gnu ("One of our most sought-after items ... "). Plus an FSF-branded antisurveillance webcam guard. Maybe Dr. Seuss can write a new book: "How the Geeks Stole Christmas." Because this newfound interest in the geek demographic seems to have spread to the largest sites of all. Google searches on "Gifts for Programmers" now point to a special page on Amazon with suggestions like Linux crossword puzzles. But what coder could resist a book called " Cooking for Programmers? "Each recipe is written as source code in a different programming language," explains the book's description... The book is filled with colorful recipes — thanks to syntax highlighting, which turns the letters red, blue and green. There are also real cooking instructions, but presented as an array of strings, with both ingredients and instructions ultimately logged as messages to the console... Some programmers might prefer their shirts from FreeWear.org, which donates part of the proceeds from every sale to its corresponding FOSS project or organization. (There are T-shirts for Linux, Gnome and the C programming language — and even one making a joke about how hard it is to exit Vim.) But maybe it all proves that there's something for everybody. That's the real heartwarming message behind these extra-geeky Christmas gifts — that in the end, tech is, after all, still a community, with its own hallowed traditions and shared celebrations. It's just that instead of singing Christmas carols, we make jokes about Vim.

Quilter’s AI designs dual-PCB system in record time  TechRadar

"On Saturday, videos shared widely on social media showed Waymo vehicles stopped mid-intersection with hazard lights flashing, forcing other cars to maneuver around them," reports the San Francisco Chronicle. The Independent notes that "Without working traffic lights, the driverless cars were seemingly left confused, with many halting in their tracks and causing major traffic jams. Local riders and pedestrians shared photos and videos of the vehicles stuck at intersections with long lines of drivers piling up behind them..." In some instances, several Waymos were piled up in front of a single intersection. "6 Waymos parked at a broken traffic light blocking the roads. Seems like they were not trained for a power outage," another social media user wrote. More from CNBC: San Francisco resident Matt Schoolfield said he saw at least three Waymo autonomous vehicles stopped in traffic Saturday around 9:45 p.m. local time, including one he photographed near Arguello Boulevard and Geary Street. "They were just stopping in the middle of the street," Schoolfield said. The power outages began around 1:09 p.m. Saturday and peaked roughly two hours later, affecting about 130,000 customers, according to Pacific Gas and Electric. As of Sunday morning, about 21,000 customers remained without power, mainly in the Presidio, the Richmond District, Golden Gate Park and parts of downtown San Francisco. PG&E said the outage was caused by a fire at a substation that resulted in "significant and extensive" damage, and said it could not yet provide a precise timeline for full restoration... Amid the disruption, Tesla CEO Elon Musk posted on X: "Tesla Robotaxis were unaffected by the SF power outage." Unlike Waymo, Tesla does not operate a driverless robotaxi service in San Francisco. Tesla's local ride-hailing service uses vehicles equipped with "FSD (Supervised)," a premium driver assistance system. The service requires a human driver behind the wheel at all times... The Waymo pause in San Francisco indicates cities are not yet ready for highly automated vehicles to inundate their streets, said Bryan Reimer, a research scientist at the MIT Center for Transportation and co-author of "How to Make AI Useful." "Something in the design and development of this technology was missed that clearly illustrates it was not the robust solution many would like to believe it is," he said. [He recommends "human backup systems in place around highly automated systems, including robotaxis."] State and city regulators will need to consider what the maximum penetration of highly automated vehicles should be in their region, Reimer added, and AV developers should be held responsible for "chaos gridlock," just as human drivers would be held responsible for how they drive during a blackout. Waymo did not say when its service would resume and did not specify whether collisions involving its vehicles had occurred during the blackout.

"Perhaps no group of fans, industry workers, and consumers is more intense about AI use than gamers...." writes New York magazine's "Intelligencer" column: Just this month, the latest Postal game was axed by its publisher, which was "overwhelmed with negative responses" from the "concerned Postal community" after fans spotted AI-generated material in the game's trailer. The developers of Arc Raiders were accused of using AI instead of voice actors, leading to calls for boycotts, while the developers of the Call of Duty franchise were called out for AI-generated assets that players found strewn across Black Ops 7.Games that weren't developed with generative AI are getting caught up in accusations anyway, while workers at Electronic Arts are going to the press to describe pressure from bosses to adopt AI tools. Nintendo has sworn off using generative AI, as has the company behind the Cyberpunk series. Valve, the company that operates Steam, now requires AI disclosures on listed games and surveys all submitters. Perhaps sensing the emergence of a new constituency, California congressman Ro Khanna responded in November to the Call of Duty backlash:"We need regulations that prevent companies from using AI to eliminate jobs to extract greater profits," he posted on X.... AI is often seen as a tool for managers to extract more productivity and justify layoffs. Among players, it can foster a sense that gamers are being tricked or ripped off, while also dovetailing with more general objections to generative AI. It can sometimes be hard to tell whether gamer backlash is a bellwether or an outlier, an early signal from our youngest major creative industry or a localized and unique fit of rage. The sheer number of incidents here suggests the former, which foretells bitter, messy, and confusing fights to come in entertainment beyond gaming — where, notably, technologies referred to as "AI" have previously been embraced with open arms. And now "the price of the sort of memory PC gamers most want to buy has skyrocketed" (per Tom's Hardware). "The rush to build data centers is making it much more expensive to game. Nobody's going to be happy about that." Insider Gaming shares another example of anti-AI sentiment in the gaming industry: The Indie Game Awards took place on December 18, and, as many could assume, Clair Obscur: Expedition 33 took home the awards for Game of the Year and Debut Game. However, things have changed and The Indie Game Awards are making a big decision to strip the Clair Obscur and developer Sandfall Interactive of their awards over the use of gen AI in the game. In an announcement made on Saturday afternoon, Six One Indie, the creators of the show, said that it's removal comes after the discovery after voting was done, and the show was recorded. "The Indie Game Awards have a hard stance on the use of gen AI throughout the nomination process and during the ceremony itself," the statement reads. "When it was submitted for consideration, representatives of Sandfall Interactive agreed that no gen AI was used in the development of Clair Obscur: Expedition 33. Polygon notes the award-stripping is "due to inclusion of generative AI assets at launch that were quickly patched out." Quotes from earlier in the year from Sandfall Interactive's FranÃois Meurisse made the rounds on social media last week amid a news cycle caught up in the use of generative AI in games... In June, the Spanish outlet El País published a story including an interview conducted around Clair Obscur's launch, in which Meurisse admitted that Sandfall used a minimal amount generative AI in some form during the game's development... Clair Obscur: Expedition 33 launched with what some suspected to be AI-generated textures that, as it clarified to El País, were then replaced with custom assets in a swift patch five days after release.

GnuCash 5.14 Open-Source Accounting Software Adds Support for US Bonds  9to5Linux

An anonymous reader shared this report from the site It's FOSS: Linux gives you plenty of ways to install software: native distro packages, Flatpak, Snap, AppImage, source builds, even curl-piped installers. The catch is that each one solves a different problem, yet none of them fully eliminates the "works here, breaks there" reality across all distros. Package Forge (PkgForge) is a new project with a narrower mission: deliver truly distro-independent portable applications that run the same way across systems.... It's not a new packaging format in and of itself, nor is it trying to replace AppImages. Instead, it's an ecosystem that publishes portable packages and static binaries in curated repositories, paired with a package manager designed to install and manage them. One of the ways PkgForge stands out from some portable app efforts on Linux is its focus on accessible documentation and a security-minded distribution model. The project primarily delivers prebuilt binary packages, keeps transparent build logs, and relies on checksum verification. This helps reduce the spread of ad-hoc install scripts and the need for local compilation, which has long been a common pattern when downloading Linux software directly (and still is for many projects today). To make life easier for the end-user, the project maintains its own frontend, called Soar... which you can use like an additional package manager, and let it handle installation, updates, and system integration. It also allows you to search for apps and utilities without having to dig through the repos online. Alternatively, you can search the PkgForge repos manually, and download and manage individual portable packages on your own. This is preferable if you're building a portable toolkit on a USB drive, testing a single app temporarily, or simply want full control over where files live... Even if it doesn't replace Flatpak, Snap, or AppImage, it helps give definition to what a more flexible, truly distro-independent future for portable Linux apps could look like.

Ubuntu 26.04 LTS Confirms its Kernel Version  OMG! Ubuntu

Long-time Slashdot reader theodp writes: Last September, tech-backed nonprofit Code.org pledged to engage 25 million K-12 schoolchildren in an "Hour of AI" this school year. Preliminary numbers released this week by the Code.org Advocacy Coalition showed that [halfway through the five-day event Computer Science Education Week] 13.1 million users had participated in the inaugural Hour of AI, attaining 52.4% of its goal of 25 million participants. In a pivot from coding to AI literacy, the Hour of AI replaced Code.org's hugely-popular Hour of Code this December as the flagship event of Computer Science Education Week (December 8-14). According to Code.org's 2024-25 Impact Report, "in 2024–25 alone, students logged over 100 million Hours of Code, including more than 43 million in the four months leading up to and including CS Education Week." Minecraft participated with their own Hour of AI lessons. ("Program an AI Agent to craft tools and build shelter before dusk falls in this iconic challenge!") And Google contributed AI Quests, "a gamified, in-class learning experience" allowing students to "step into the shoes of Google researchers using AI to solve real-world challenges." Other participating organizations included the Scratch Foundation, Lego Education, Adobe, and Roblox. And Microsoft contributed two — including one with their block-based programming environment Microsoft MakeCode Arcade, with students urged to "code and train your own super-smart bug using AI algorithms and challenge other AI bugs in an epic Tower battle for ultimate Bug Arena glory!"
