Meta's smart glasses face new questions from two U.S. Senators, reports Gizmodo. Oregon Sen. Ron Wyden and Massachusetts Sen. Edward Markey "are requesting that Meta provide more information before Thanksgiving on whether it conducted detailed human rights due diligence and safety testing on the product before releasing it," reports Gizmodo. The Senators also requested information from Meta about " how it evaluated the privacy risks posed by the glasses, and what kinds of safeguards are currently in place." "Although Meta identified risks to bystander privacy and vulnerable populations before launching its glasses in 2021, it nevertheless launched a product tailor-made for invading the privacy of its users and bystanders," [the senators wrote in a letter Thursday...] The glasses have also been spotted on ICE agents during raids, and have raised potential surveillance concerns. The surveillance fears were even reportedly raised by the New York Police Department's counterterrorism unit in a memo issued earlier this year.... "Meta's own disclosures confirm that imagery processed through its glasses' visual AI features may be retained and used to train AI systems, including with the assistance of human reviewers," the senators' letter states, calling the practice an invasion of privacy. "Retaining that material for AI development, thereby extending the period during which it can be accessed, disclosed, or misused, exploits people's highly sensitive information for Meta's commercial benefit."

Boom Supersonic's plans to launch its Overture passenger jet by 2029 are facing growing doubts as the company pivots toward manufacturing natural gas turbines for AI data centers. Ars Technica reports: One of the company's first customers, United Airlines CEO Scott Kirby, has expressed doubts about Boom's original plan to deliver the first Overture supersonic airliner in 2029. Kirby's latest frank assessment came during an interview with the Office Hours: Business Edition podcast that appeared on October 28, 2026. "'29 is their official timeline," Kirby told podcast host Monica Langley. "It's not going to happen in '29 -- it's going to take longer." [...] Much of Boom's recent focus has been on developing natural gas turbines to power AI data centers as an additional revenue stream. On October 22, the company unveiled another factory in Centennial, Colorado, dedicated to producing a 42-megawatt natural gas turbine called Superpower for data centers. [...] Boom described its new Superpower factory as making turbine parts while still undergoing construction. It aims to deliver the first gas turbines to AI data center customers in mid-2027 while ramping up annual production to 25 turbines in 2028 and 50 turbines by 2029. [...] Still, Boom has characterized the development of a gas turbine for data centers as being synergistic with its design of the Symphony engine for the Overture airliner. During the October announcement, it also described having completed a prototype turbine core, called Sprint Core, that is intended to eventually power both the Superpower gas turbine and Symphony engine for the airliner. That turbine core is set to undergo testing at the Colorado Air & Space Port, with Boom planning to fire the turbine for the first time before Thanksgiving. That would be a concrete development milestone, but the company still has much to do in proving it can get both its AI data center and supersonic airliner ventures off the ground.

Sculpt OS 26.10 brings quite a few new features, like scalable cursors, support for UK keyboards, better webcam support, and more, but the real meat of this release is much tastier. First, Sculpt 26.10 is the first version based on Genode's custom microkernel instead of relying on a 3rd-party kernel. This kernel - designed from the ground up for the needs of Genode and Sculpt OS in particular - is not only more "micro" than any other of the microkernels supported by Genode, it also solves long-standing deficiencies concerning CPU scheduling and kernel-memory management. Sculpt OS finally stands on Genode's own footing! Finally, Sculpt OS 26.10 pays tribute to this year's overall theme of "building bridges" by featuring our software development kit (Goa SDK) running directly on Sculpt OS without virtualization. This entails a wealth of tooling including GCC, Binutils, Git, Sequoia, Expect, Curl, man, Make, and CMake having landed on Genode. Although still young and not time-tested yet, it shows what's possible today and allows us developers to gradually shift more and more development routine into this self-hosted environment, stressing the general-purpose qualities of Genode and motivating further optimizations. ↫ Sculpt OS release 26.10 announcement This new release also completes the transition from XML to Genode's own HID language for configuration, moves from VirtualBox 6 to 7, and upgrades a whole slew of its Linux-based drivers

Raymond Chen published another story from the Windows development trenches, this time about what happens when you hold down the power button. If you hold a PC's power button for 12 seconds, it will turn off at the hardware level without notifying the operating system. This is a safety feature so that you can turn of the computer even if the operating system's "Shut down" command isn't working. After eight seconds of the power button being held down, the Windows kernel realizes that the user is trying to do a force-power-off of the system, and it quickly takes a kernel dump that can be uploaded to the Windows Error Reporting service the next time you turn the system on. ↫ Raymond Chen I'm a bit confused by these numbers, because I have never seen a PC take this long to power off when holding down the power button; usually it takes only a few seconds to do so, meaning Windows would never generate said kernel dump. I tried reading through the various ATX specification documents to find more information on this, but then I remembered I'm not an electrical engineer so I have no idea what I'm looking at. The baseline is that ATX always provides standby power to the motherboard, and pressing the power button shorts the power button pin to ground, telling the PSU to power on fully. Pressing the power button if the computer is running tells the operating system to initiate a shutdown (although you can change this behaviour), but if you hold the button down for a certain number of seconds, it forces a power-off. So far, so good; basic information. It seems that the length of time you need to hold down the power button to force a power-off is dependent on the motherboard in question, handled by a microcontroller or some other IC. Virtually every source I can find says this timing is set to about 4-5 seconds, which is quite a bit shorter than the number of seconds given by Chen. Perhaps motherboard manufacturers consider the 12 seconds to be too long, and just do their own thing, regardless what the ATX specification suggests? What further complicates matters is that Chen details how the kernel dumps created after pressing the power button for 8 seconds do, in fact, get sent to Microsoft once the computer turns on again. In fact, he is one of the people who gets to see these dumps and respond to them, so obviously they are indeed rolling in. Does this mean there's a huge number of computers out there that require you to hold down the power button for 12 seconds to force a shutdown that nobody's ever seen? These emergency kernel dumps are internally classified as "long power button hold" (LPBH) failures. One of the pieces of information recorded in these emergency kernel dumps is whether the screen consists entirely of black pixels. Those failures are sub-classified as "black screen LPBH", and they go to a special virtual team for analysis. (I happen to be a member of this black screen LPBH team.) ↫ Raymond Chen What's going on here? Obviously, I'm not going to doubt Chen, so there must be something here I don't quite understand or that I'm missing. The ATX specification might suggest 12 seconds, but could Windows perhaps adapt its kernel dump behaviour - dumping much sooner than 8 seconds - based on the motherboard it's running on, maybe through information provided by the chipset drivers? I would love it if someone more knowledgeable than me can help us unravel this small mystery.

From curl 8.12 through 8.16, config files could slice variable values and include other config files without an explicit depth cap. Together, these features let curl simulate any two-counter Minsky program. Under the usual idealization of unbounded strings and resources, this construction was Turing-complete. Curl 8.17.0 added a five-level include cap that breaks this reduction. ↫ Nicolas Seriot Neat.

Google's first experimental space-based data center is operational after launching earlier this month, successfully running its Gemma 4 AI model aboard a satellite and generating a haiku about being in orbit. TechCrunch reports: The satellite, which carries four Google Tensor Processing Units (TPUs) and generates up to 1 kW of electricity, is intended to pave the way for future networks of close-flying satellites performing large inference workloads in orbit. However, the power demands of the TPU mean it can only turn one on for about 20 minutes at a time, complicating the already tricky business of space-to-ground communications. After a commissioning process that tested out the satellite's subsystems over about three weeks, the spacecraft was ready to work. When engineers on the ground sent their first prompt this week, they asked the model pre-loaded onto the satellite, Google DeepMind's Gemma 4, to write a haiku about being in space. And thus: Blue marble below Data streams in silent grace Starlight feeds my core. The ongoing test campaign will examine how the chips perform under thermal stress and in the space radiation environment. [...] If the TPUs onboard this spacecraft prove capable, the next step will be launching two more satellites equipped with the advanced chips in 2027. Those spacecraft will support higher power generation and demonstrate inter-satellite optical links.

This meant binaries to read/write individual file types, better error messages, extensive specifications and of course exports to common dataformats like JSON.

Over the last few weeks, we have been doing research on the integration of our official distribution packages when installed on a target system. In this context we have been looking at the current uses of alpm-install-scriptlet(5) files and alpm-hooks(5) in around 120 package source repositories (alpm-source-repo(7)) to better understand the underlying functionality and use-cases these two integrations offer and target. In this article we are going to look at how these two systems work, how Arch Linux is currently using them and attempt to provide suggestions for when to use which.
