Tuesday Pew Research announced their newest findings: that 54% of America's teens use AI help with schoolwork: One-in-five teens living in households making less than $30,000 a year say they do all or most of their schoolwork with AI chatbots' help. A similar share of those in households making $30,000 to just under $75,000 annually say this. Fewer teens living in higher-earning households (7%) say the same." "The survey did not ask students whether they had used chatbots to write essays or generate other assignments..." notes the New York Times. "But nearly 60% of teenagers told Pew that students at their school used chatbots to cheat 'very often' or 'somewhat often.'" Agreeing with that are the Pew Researchers themselves. "Our survey shows that many teens think cheating with AI has become a regular feature of student life." One worried teenager still told the researchers that AI "makes people lazy and takes away jobs." But another teenager told the researchers that "Everyone's going to have to know how to use AI or they'll be left behind." Thanks to long-time Slashdot reader theodp for sharing the article.

A start-up called Reflect Orbital "proposes to use large, mirrored satellites to redirect sunlight to Earth at night," reports the Washington Post, "with plans to bathe solar farms, industrial sites and even entire cities in light that could, if desired, reach the intensity of daylight...." Slashdot noted their idea in 2022 - but Reflect Orbital now expects to launch its first satellite in April, according to the article. "But its grand vision is largely 'aspirational,' as its young founder, Ben Nowack, told me..." Reflect Orbital's Nowack describes a scene right out of sci-fi: An extremely bright star appears on the northern horizon and makes its way across the sky, illuminating a 5-kilometer circle on Earth, then setting on the southern horizon about five minutes later, just as another such "star" appears in the north. To make the night even brighter, a customer could make 10 "stars" appear at once in the north by ordering them on an app. Two such artificial stars are in development in Reflect Orbital's factory. Nowack showed them to me on a Zoom call. The first to launch is 50 feet across, but he plans later to build them three times that size. If all goes according to plan, he'll have 50,000 of them circling the Earth in 2035 at an altitude of around 400 miles. Nowack plans to start selling the service "in mostly developing nations or places that don't have streetlights yet." Eventually, he thinks, he can illuminate major cities, turn solar fields and farms into round-the-clock operations for any business or municipality that pays for it. He likened his technology to the invention of crop irrigation thousands of years ago. "I see this as much the same thing," he said, arguing that people would no longer have to "wait for the sun to shine." The article adds that Elon Musk's SpaceX "wants to launch as many as a million satellites to serve as orbiting data centers - 70 times the number of satellites now in orbit." (America's satellite-regulation Federal Communications Commission grants a "categorical exclusion" from environmental review to satellites on the grounds that their operations "normally do not have significant effects on the human environment.") The public comment periods for the two proposals close on March 6 and March 9.

An anonymous reader quotes a report from Ars Technica: Google on Friday unveiled its plan for its Chrome browser to secure HTTPS certificates against quantum computer attacks without breaking the Internet. The objective is a tall order. The quantum-resistant cryptographic data needed to transparently publish TLS certificates is roughly 40 times bigger than the classical cryptographic material used today. Today's X.509 certificates are about 64 bytes in size, and comprise six elliptic curve signatures and two EC public keys. This material can be cracked through the quantum-enabled Shor's algorithm. Certificates containing the equivalent quantum-resistant cryptographic material are roughly 2.5 kilobytes. All this data must be transmitted when a browser connects to a site. To bypass the bottleneck, companies are turning to Merkle Trees, a data structure that uses cryptographic hashes and other math to verify the contents of large amounts of information using a small fraction of material used in more traditional verification processes in public key infrastructure. Merkle Tree Certificates, "replace the heavy, serialized chain of signatures found in traditional PKI with compact Merkle Tree proofs," members of Google's Chrome Secure Web and Networking Team wrote Friday. "In this model, a Certification Authority (CA) signs a single 'Tree Head' representing potentially millions of certificates, and the 'certificate' sent to the browser is merely a lightweight proof of inclusion in that tree." [...] Google is [also] adding cryptographic material from quantum-resistant algorithms such as ML-DSA (PDF). This addition would allow forgeries only if an attacker were to break both classical and post-quantum encryption. The new regime is part of what Google is calling the quantum-resistant root store, which will complement the Chrome Root Store the company formed in 2022. The [Merkle Tree Certificates] MTCs use Merkle Trees to provide quantum-resistant assurances that a certificate has been published without having to add most of the lengthy keys and hashes. Using other techniques to reduce the data sizes, the MTCs will be roughly the same 64-byte length they are now [...]. The new system has already been implemented in Chrome.

The file system of the Windows operating system is NTFS, whether you're running it on a desktop/laptop or server. It's the only file system Windows can run on and boot from, at least officially, so you're not even given a choice of file systems for the boot volume like you are on, say, desktop Linux. That's about to change, though: Microsoft has finally announced that Windows Server will be able to boot from ReFS. We're excited to announce that Resilient File System (ReFS) boot support is now available for Windows Server Insiders in Insider Preview builds. For the first time, you can install and boot Windows Server on an ReFS-formatted boot volume directly through the setup UI. With ReFS boot, you can finally bring modern resilience, scalability, and performance to your server's most critical volume - the OS boot volume. ↫ chcurlet-msft at Microsoft's Tech Community Without diving too much into the weeds, ReFS can roughly be seen as Microsoft's answer to modern file systems like ZFS and Btrfs, with comparable design goals and feature sets. It's been around since 2012, but only for Windows Server, and with every Windows Server release since, the company has improved performance, added new features, and fixed bugs. Now, in 2026, it seems Microsoft thinks ReFS is ready to be used as a bootable file system for Windows Server. If you want to try this for yourself, you need to be a Windows Insider and make sure you have Windows Server build 29531.1000.260206-1841 or newer. During installation, the Windows installer will ask you to choose between NTFS and ReFS; the rest of the installation process will be pretty much the same as before. Now all we need is to wait for ReFS to become an option on client versions of Windows too, which would mark - arguably - only the second time in history Windows transitioned from one default filesystem to the another.

Encryption backdoors, social media bans for children, creepy age verification for applications - what will they think of next? The latest brilliant idea by US lawmakers sure is a hell of a doozy: legally mandated age verification in every single operating system. Colorado's SB26-051, introduced last month, would require operating systems to register the owner's age, which third-party apps can then leverage to determine if the user is an adult. The bill calls for the device owner to register their birthdate or age, but for the purposes of creating an "age bracket," which can then be shared to an app developer through an API to learn their age range, according to BiometricUpdate.com. Ball also said the legislation was based on California's bill AB 1043, which was passed last year. It too requires OS makers to create a way for the device owner to register their age bracket, which can then be shared to app developers over an API. The California law starts to take effect January 1, 2027. ↫ Michael Kan at PCMag Age verification to protect children sounds innocent enough, but if you have more than two brain cells to rub together it's crystal clear that what we're really looking at is the true end of privacy and online anonymity. If age verification is only used by certain applications, it's easy enough to avoid them, but if it becomes part of Windows, desktop Linux, Android, it's truly game over. Nobody will be anonymous online ever again, and nobody will have any sense of privacy left when opening up their computer. Worse yet, if you do end up using an operating system that doesn't adhere to this law, or you hack out or circumvent the age verification nonsense, you'll automatically become an easy target for law enforcement. Clearly, if you circumvent age verification, you must be up to no good, right? Of course, as we've seen in countries with heavily deteriorating democracies and freedoms, like the US or Hungary, even merely opposing the government will be classified as "up to no good", and let's not even get started about the various minorities these countries are actively trying to eradicate. If something like this is enshrined in law in your country, you're fucked.

FreeBSD has its jails technology, and it seems NetBSD might be getting something similar soon. Jails for NetBSD aims to bring lightweight, kernel-enforced isolation to NetBSD. The system is intended to remain fully NetBSD-native. Isolation and policy enforcement are integrated into the kernel's security framework rather than implemented in a separate runtime layer. It does not aim to become a container platform. It does not aim to provide virtualization. ↫ Matthias Petermann It has all the usual features you have come to expect from jails, like resource quota, security profiles, logging, and so on. Processes inside jails have no clue they're in a jail, and using supervisor mode, jails are descendent from a single process and remain visible in the host process table. Of course, there's many more features listed in the linked article. It's in development and not a default part of NetBSD at this time. The project, led by Matthias Petermann, is developed out of tree, with an unofficial NetBSD 10.1 ISO with the jails feature included available as well.

While starting this post I realized I have been maintaining personal infrastructure for over a decade! Most of the things I've self-hosted is been for personal uses. Email server, a blog, an IRC server, image hosting, RSS reader and so on. All of these things has all been a bit all over the place and never properly streamlined. Some has been in containers, some has just been flat files with a nginx service in front and some has been a random installed Debian package from somewhere I just forgot.
