There's already 5,000 sensors embedded in Antarctica's ice to look for evidence of neutrinos, reports the Washington Post. But in November scientists drilled six new holes at least a mile and a half deep and installed cables with hundreds more light detectors - an upgrade to the massive 15-year-old IceCube Neutrino Observatory to detect the charged particles produced by lower-energy neutrinos interacting with matter: When they do, the neutrinos produce charged particles that travel through the ice at nearly the speed of light, creating a blue glow called Cherenkov radiation... "Within the first couple years, we should be making much better measurements," [said Erin O'Sullivan, an associate professor of physics at Uppsala University in Sweden and a spokesperson for the project.] "There's hope to expand the detector, by an order of magnitude in volume, so the important thing there is we're not just seeing a few neutrino point sources, but we're starting to be a true telescope. ... That's really the dream." The scientists spent seven years planning the upgrade, according to the article. "To drill holes a mile and a half deep takes about 30 hours, and 18 more hours to return to the surface," the article points out. "Then, the race begins because almost immediately, the hole starts to shrink as the water refreezes." ("If it takes too much time, the principal investigator says, "the instruments don't fit in anymore!")

Interesting Engineering reports: US tech giant Google announced on Tuesday that it will build a new data center in Pine Island, Minnesota. The new facility will be powered by 1.9 gigawatts (GW) of clean energy from wind and solar, coupled with a 300-megawatt battery, claimed to be the 'world's largest', with a 30-gigawatt-hour (GWh) capacity and 100-hour duration... The planned battery would dwarf a 19 GW lithium-ion project in the UAE... Form Energy's batteries work very differently from most large batteries today. Instead of using lithium like the batteries in electric cars, they store electricity by making iron rust and then reversing the rusting process to release the energy when needed... Form's iron-air batteries are heavier and less efficient than their counterparts; they can only return about 50% to 70% of the energy used to charge them, while lithium-ion batteries return more than 90%. However, Form's batteries have one distinct advantage. They are cheaper than lithium-ion batteries, costing about $20 per kilowatt-hour of storage, which is almost three times as cheap... It will store 150 MWh of electricity and can supply to the grid for up to 100 hours, delivering about 1.5 MW at peak output. Thanks to long-time Slashdot reader schwit1 for sharing the article.

CNN reports that images from Iran's capital "have shown cars jammed along Tehran's street, with heavy traffic on major roads after today's wave of attacks by the US and Israel." And though Iran has a population of 93 million, the attacks suddenly plunged Iran into "a near-total internet blackout with national connectivity at 4% of ordinary levels," according to internet monitoring experts at NetBlocks. CNN reports: Since Iran's brutal crackdown earlier this year, the regime has made progress to allow only a subset of people with security clearance to access the international web, experts said. After previous internet shutdowns, some platforms never returned. The Iranian government blocked Instagram after the internet shutdown and protests in 2022, and the popular messaging app Telegram following protests in 2018. The International Atomic Energy Agency announced an hour ago that they're "closely monitoring developments" - keeping in contact with countries in the region and so far seeing "no evidence of any radiological impact." They're also urging "restraint to avoid any nuclear safety risks to people in the region."

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.
