The New York Times checks in on U.S. university researchers and start-ups trying to create domestic rare-earth processing facility: There is too little money to be made in rare earths for the elements to be of much interest to mining giants, so the challenge of reestablishing a domestic industry has fallen to small companies like Phoenix Tailings, a Boston-area startup that runs the metal-making plant in Exeter, New Hampshire. A handful of other companies in the United States are processing rare earths in small quantities, including MP Materials, which owns a mine in Mountain Pass, California, and recently began producing rare-earth metal in Fort Worth, Texas. Similar efforts are underway in Europe and Asia. "It's small volumes of low-value materials that are very expensive to process," said Elsa Olivetti, a materials science and engineering professor at the Massachusetts Institute of Technology. "Meaning it's hard to make money." Phoenix Tailings' New Hampshire operation is about 2 months old, housed in a converted medical device plant. The company buys metric-ton bags of powder - a mixture of neodymium and praseodymium bound with oxygen - from mining and refining companies in the United States, South America and Australia. It funnels that flour-like material into a drying oven and eventually into furnaces that heat it to the temperature of volcanic lava. This circuit takes up less than 15,000 square feet and is designed to generate no emissions other than those associated with the electricity Phoenix Tailings uses. The closed-loop design distinguishes this process from the more energy-intensive techniques used in China, where workers scoop up molten metal with ladles. That approach releases perfluorocarbons, potent greenhouse gases that do not break down easily. In late 2024 the company was three weeks from bankruptcy - but it's recently been valued at $189 million.

Desktop Classic System is an operating system based on Debian and a customized version of the MATE Desktop Environment that hearkens back to, but is not a direct copy of, the classic Mac OS. DCS seeks to provide and sometimes even improve upon the conceptual simplicity offered by the old Macintosh. ↫ Desktop Classic System website I'm usually not particularly interested in reporting on random Linux distributions, but any one of them that defaults to a proper spatial file manager is one that I will highlight. I'm not entirely sure if this is just a supported feature of MATE's file manager, or something more custom - there are some patches to Caja here, as mentioned - but spatial file managers are a dying breed and that's a shame. They're hard to implement and even harder to get right, which is probably why few people take on the challenge. Other than that, DCS isn't particularly revolutionary or special, but I'd love for more Linux distributions to look back at what we've lost, and see if we can bring those things back.

KDE developer Herz published a detailed look at the immense amount of work they've done cleaning up the developer onboarding documentation for KDE. All that just to say that I'm finally content with the state of beginner onboarding docs in our KDE Developer Platform. That is to say, all the beginner docs fixes I wanted to add to Develop are either already there or have merge requests ready or almost ready. ↫ Herz at rabbitictranslator.com Judging by the article, KDE's developer documentation really were in need of major work, and it's great to see that thankless task being done. One of the areas where KDE lags behind GNOME is that the latter has a more vibrant application ecosystem, with tons of great GNOME applications under active development. Now, I'm not saying it's the state of KDE's documentation is the sole reason for this, but I'm sure it wasn't helping either. Improving documentation is not a particularly glamorous task, but it's vitally important nonetheless.

Reddit "has overtaken TikTok as Britain's fourth most-visited social media service," reports the Guardian: The platform has undergone huge growth over the last two years, with an 88% increase in the proportion of UK internet users it reaches. Three in five Brits online now encounter the site, up from a third in 2023, according to Ofcom. Its popularity is rising fastest with younger internet users. It is now the sixth most visited organisation of any kind by UK users aged between 18 and 24, up from 10th a year earlier. More than three-quarters of that cohort now visit it.... The UK is a boom market for the platform, with the second largest user base behind the US, according to company records. A series of factors are behind its rise. However, a change in Google's search algorithms last year to prioritise helpful content from discussion forums appears to have been a significant driver. A recent deal with Google that allows the company to train its AI model on Reddit's content also appears to have provided a boost. Reddit is the most-cited source for Google AI overviews, which is likely to see more people directed to its forums. It has a similar deal with OpenAI, which owns the most popular AI chatbot, ChatGPT. According to the article, Reddit "believes it is also benefiting from shifting internet habits, as younger users seek out human-generated reviews and opinions."

An anonymous reader shared this report from Electrek: Tesla has released a new video showing a Tesla Semi truck charging at a massive 1.2 megawatts (MW), finally giving us a clear look at the charging speeds that will enable long-haul electric trucking...> Tesla claimed the Semi would be able to charge 70% of its range in 30 minutes. For a truck with a 500-mile range and an estimated battery pack of around 800-900 kWh, that requires an incredibly high power output, well beyond the 250 kW or even 350 kW we see on passenger EVs in North America. Today, the official Tesla Semi account on X released a video showing exactly that. In the video, Tesla engineers are seen monitoring a charging session where the power output climbs to a peak of 1.2 MW (1,206 kW). This is consistent with the capabilities Tesla announced for its new V4 Cabinet architecture earlier this year. The V4 cabinets are designed to support 400V-1000V vehicle architectures and can deliver up to 500 kW for cars (like the Cybertruck) and up to 1.2 MW for the Semi. There is some information missing from the video. For example, we don't see the state-of-charge of the truck, so we don't at what battery percentage Tesla Semi can achieve and maintain this charge rate. Peak speed is one thing, but sustaining that power without overheating the pack or the cable is the real challenge. The liquid-cooled charging cable and the immersion-cooled connector (part of the Megawatt Charging System or a high-power proprietary Tesla solution, though Tesla has been leaning toward MCS compatibility) seem to be doing their job.... This comes just as Tesla is gearing up for volume production of the Semi at its new factory expansion near Gigafactory Nevada. The automaker is targeting a start of production in the first half of 2026 and a ramp up to volume production in the second half.

It shouldn't be surprising that the HP-UX FAQ eventually grew an entry for "how can I make a 712 run headless". It was possible, and to do it you had to change the firmware "console" path. The 712 firmware would not allow you to do this, to keep you locked to a keyboard and frame buffer console, but some of the HP-UX standalone tools could be used to change this without the firmware getting in the way, so the FAQ recipe was roughly "abort the boot sequence, at the BOOT_ADMIN> prompt, do not start the HP-UX kernel but some diagnostic tool, and then at the tools prompt, type a magic sequence without any mistake or you'll be very, very, very sorry". There was no exaggeration in these words: the magic sequence is conspath 2/0/4.0x283, which is everything but intuitive and easy to remember. ↫ Miod Vallat What a great story.

Same as last year, this is a summary of what I've been up to throughout the year. See also the recap/retrospection published by my friends (antiz, jvoisin, orhun).

• Uploaded 467 packages to Arch Linux
  • Most of them being reproducible, meaning I provably didn't abuse my position of compiling the binaries
  • 35 of them are signal-desktop
  • 29 of them are metasploit
• Made 53 uploads to Debian
  • All of them being related to my work in the debian-rust team, that I've been a part of since 2018

With the update to driver version 590, the NVIDIA driver no longer supports Pascal (GTX 10xx) GPUs or older. We will replace the nvidia package with nvidia-open, nvidia-dkms with nvidia-open-dkms, and nvidia-lts with nvidia-lts-open. Impact: Updating the NVIDIA packages on systems with Pascal, Maxwell, or older cards will fail to load the driver, which may result in a broken graphical environment. Intervention required for Pascal/older users: Users with GTX 10xx series and older cards must switch to the legacy proprietary branch to maintain support:

• Uninstall the official nvidia, nvidia-lts, or nvidia-dkms packages.
• Install nvidia-580xx-dkms from the AUR

Users with Turing (20xx and GTX 1650 series) and newer GPUs will automatically transition to the open kernel modules on upgrade and require no manual intervention.
