"Within 24 hours of the first US-Israeli strikes on Iran, ships in the region's waters found their navigation systems had gone haywire," reports CNN, "erroneously indicating that the vessels were at airports, a nuclear power plant and on Iranian land. "The location confusion was a result of widespread jamming and spoofing of signals from global positioning satellite systems." Used by all sides in conflict zones to disrupt the paths of drones and missiles, the process involves militaries and affiliated groups intentionally broadcasting high-intensity radio signals in the same frequency bands used by navigation tools. Jamming results in the disruption of a vehicle's satellite-based positioning while spoofing leads to navigation systems reporting a false location. Though commercial vessels are not the target, the electronic interference disrupted the navigation systems of more than 1,100 commercial ships in UAE, Qatari, Omani and Iranian waters on February 28, according to a report from Windward, a shipping intelligence firm. Jamming and spoofing also slowed marine traffic moving through the Strait of Hormuz, a congested shipping lane that handles roughly 20% of the world's oil and gas exports and where precise navigation is essential, Windward's data showed.... Daily incidents have more than doubled, rising from 350 when the conflict began to 672 by March 2, the firm reported. As use of this warfare tactic grows, experts worry the impacts could reach far beyond battlespaces.... In June 2025, electronic interference with navigation systems was thought to be a factor in the collision between two oil tankers, Adalynn and Front Eagle, off the coast of the UAE... The number of global positioning system signal loss events affecting aircraft increased by 220% between 2021 and 2024, according to data from the International Air Transport Association. Last year, IATA said that the aviation industry must act to stay ahead of the threat. Cockpits are seeing their navigation displays "literally drift away from reality," said a commercial pilot, who didn't want to be identified because he was not permitted to speak publicly. He said that he and his colleagues have experienced map shifts, where the aircraft location appears to move up to 1 mile away from the actual flight path, false altitude information that leads to phantom "pull up" commands, and systems suggesting an aircraft was on a taxiway, a path that connects runways with various airport facilities, when taking off. These incidents force pilots to rely on manual actions that increase workload, often during the most exhausting points of long-haul flights, he said. "Alternative navigational tools that don't rely on GPS, but instead harness quantum technology, are also in development," the article points out, "but remain a long way off operational use."

"Seagate says it is now shipping its Mozaic 4+ HAMR-based hard drives at up to 44TB per drive," writes Slashdot reader BrianFagioli, "with production deployments already underway at two hyperscale cloud providers. "The company claims the platform is the only heat-assisted magnetic recording [HAMR] implementation currently operating at scale, and it is targeting a path from today's 4+TB per disk toward 10TB per disk, eventually enabling 100TB-class drives." In a one-exabyte deployment, Seagate estimates Mozaic could improve infrastructure efficiency by roughly 47% compared to standard 30TB drives, cutting both footprint and energy consumption... HAMR uses a tiny laser to heat the disk surface during writes, allowing higher recording density without sacrificing stability. With most major cloud storage providers reportedly qualified on the Mozaic platform, Seagate is positioning spinning disks, not flash, as the long-term answer for cost-effective AI-scale data growth.

"Reservation holders, it's finally time to get ready," writes long-time Slashdot reader AirHog. The EV news site Electrek reports: Aptera Motors, "the little startup that could," announced another important milestone... completing the first example of its flagship solar EV on its validation assembly line in Southern California... While the validation line at its headquarters remains a low-volume assembly process, its successful operation represents the startup's transition from hand-built validation SEVs to a more structured assembly line process that will be fine-tuned for mass production... With low-volume assembly now being validated, Aptera is starting to publicly utter encouraging terms like "EPA certification" and, better yet, that holy grail of "initial customer deliveries." Before then, however, the Aptera Solar EVs built on this low-volume validation line will be used for testing programs such as thermal validation, brake performance, and "some destructive testing." Aptera shared that its assembly and integration team has grown to become the largest at the startup, "reflecting the beginning of its transition from engineering development to testing and production execution"... As of March 2026, Aptera says it has over 50,000 reservations totaling over $2 billion in sales if all were to solidify following the launch of a deliverable vehicle. Clean Technica notes the vehicles' "generous cargo space that comes out to 60% more storage than a Honda Accord and 20% more storage than a Prius, according to the company." "Built with recyclable materials, this eco-friendly vehicle features a lightweight carbon fiber structure and no-welding assembly for maximum cost and production efficiency," Aptera adds. The emphasis on lightweighting supports the goal of engineering a car that can travel on the electricity provided by its onboard solar panels. The company currently advertises that the vehicle can travel 40 miles on solar power alone, with the battery providing extra juice as needed. Ideally, the car can keep recharging itself with sunlight, further elongating the time between charging sessions... [Its range is up to 1,000 miles with plug-in charging.] The new autocycle could also appeal to drivers who enjoy the challenge of hypermiling, which involves deploying a suite of driving techniques to minimize fuel consumption. Hypermiling can apply to gas-powered cars, but the magic really kicks in with the regenerative braking capability of EVs. Aptera's onboard solar panels add another dimension to the fun.

And when a Redox monthly progress report is here, Haiku's monthly report is never far behind (or vice versa, depending on the month). Haiku's February was definitely a busy month, but there's no major tentpole changes or new features, highlighting just how close Haiku is to a new regular beta release. The OpenBSD drivers have been synchronised wit upstream to draw in some bugfixes, there's a ton of smaller fixes to various applications like StyledEdit, Mail, and many more, as well a surprisingly lost list f various file system fixes, improving the drivers for file systems like NTFS, Btrfs, XFS, and others. There's more, of course, so just like with Redox, head on over to pour over the list of smaller changes, fixes, and improvements. Just like last month, I'd like to mention once again that you really don't need to wait for the beta release to try out Haiku. The operating system has been in a fairly stable and solid condition for a long time now, and whatever's the latest nightly will generally work just fine, and can be updated without reinstallation.

February has been a busy month for Redox, the general purpose operating system written in Rust. For instance, the COSMIC compositor can now run on Redox as a winit window, the first step towards fully porting the compositor from COSMIC to Redox. Similarly, COSMIC Settings now also runs on Redox, albeit with only a very small number of available settings as Redox-specific settings panels haven't been made yet. It's clear the effort to get the new COSMIC desktop environment from System76 running on Redox is in full swing. Furthermore, Vulkan software can now run on Redox, thanks to enabling Lavapipe in Mesa3D. There's also a ton of fixes related to the boot process, the reliability of multithreading has been improved, and there's the usual long list of kernel, driver, and Relibc improvements as well. A major port comes in the form of NodeJS, which now runs on Redox, and helped in uncovering a number of bugs that needed to be fixed. Of course, there's way more in this month's progress report, so be sure to head on over and read the whole thing.

One day, I suddenly wondered how to detect when a USB device is plugged or unplugged from a computer running Linux. For most users, this would be solved by relying on libusb. However, the use case I was investigating might not actually want to do so, and so this led me down a poorly-documented rabbit hole. ↫ ArcaneNibble (or R) And ArcaneNibble (or R) is taking you down with them.

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.
