NASA's Hubble Space Telescope unexpectedly captured a rare, early-stage breakup of comet C/2025 K1 (ATLAS) just days after it first began disintegrating. Phys.org reports: "Sometimes the best science happens by accident," said co-investigator John Noonan, a research professor in the Department of Physics at Auburn University in Alabama. "This comet got observed because our original comet was not viewable due to some new technical constraints after we won our proposal. We had to find a new target -- and right when we observed it, it happened to break apart, which is the slimmest of slim chances." Noonan didn't know K1 was fragmenting until he viewed the images the day after Hubble took them. "While I was taking an initial look at the data, I saw that there were four comets in those images when we only proposed to look at one," said Noonan. "So we knew this was something really, really special." Hubble caught K1 fragmenting into at least four pieces, each with a distinct coma, the fuzzy envelope of gas and dust that surrounds a comet's icy nucleus. Hubble cleanly resolved the fragments, but to ground-based telescopes, at the time they only appeared as barely distinguishable, bright blobs. [...] "Never before has Hubble caught a fragmenting comet this close to when it actually fell apart. Most of the time, it's a few weeks to a month later. And in this case, we were able to see it just days after," said Noonan. "This is telling us something very important about the physics of what's happening at the comet's surface. We may be seeing the timescale it takes to form a substantial dust layer that can then be ejected by the gas." The findings have been published in the journal Icarus.

schwit1 shares a report from the BBC: A French officer has reportedly revealed the location of an aircraft carrier deployed towards the Middle East after publicly registering a run on sports app Strava. French news outlet Le Monde first reported the officer, referred to as Arthur, logged a 35-minute run on the app while exercising on the deck of aircraft carrier Charles de Gaulle on 13 March. He used a smartwatch to record his run and upload the activity to the app, the paper said, creating a map that showed his location. [...] The location of the vessel was said by Le Monde to have been northwest of Cyprus, around 100km (62 miles) from the Turkish coast, with satellite images capturing the carrier and its escort. A representative from the French Armed Forces said the officer's behavior "does not comply with current guidelines," which "sailors are regularly made aware of."

An anonymous reader quotes a report from CNBC: The Trump administration on Friday issued (PDF) a legislative framework for a single national policy on artificial intelligence, aiming to create uniform safety and security guardrails around the nascent technology while preempting states from enacting their own AI rules. The six-pronged outline broadly proposes a slew of regulations on AI products and infrastructure, ranging from implementing new child-safety rules to standardizing the permitting and energy use of AI data centers. It also calls on Congress to address thorny issues surrounding intellectual-property rights and craft rules "preventing AI systems from being used to silence or censor lawful political expression or dissent." The administration said in an official release that it wants to work with Congress "in the coming months" to convert its framework into a bill that President Donald Trump can sign. The White House wants to codify the framework into law "this year" and believes it can generate bipartisan support, Michael Kratsios, director of the White House Office of Science and Technology Policy, said in an interview with Fox News on Thursday evening. That won't be easy in a deeply divided Congress where Republicans hold thin and often fractious majorities, and where Trump has already urged GOP lawmakers to prioritize his controversial voter-ID bill above all else ahead of the November midterms. BCLP has an interactive map that tracks the proposed, failed and enacted AI regulatory bills from each state.

Earlier this year, Microsoft openly acknowledged the sorry state of Windows 11, and made vague promises about possible improvements somewhere in the near future, but stayed away from making any concrete promises. Today, the company published a blog post with some more details, including some actual concrete, tangible changes it's going to implement over the coming two months. In coming builds, you'll be able to move the taskbar to any side of the screen, instead of it being locked to the bottom, thereby reintroducing a feature present since Windows 95. They're also scaling back their obsession with ramming "AI" in every corner of Windows, and will be removing Copilot integrations from Snipping Tool, Photos, Widgets, and Notepad. Furthermore, and this is a big one among Windows users I'm sure, Windows Update will be placed under user control once again, allowing them to ignore updates, postpone them indefinitely, reboot without applying updates, and so on. These are the tangible improvements we'll be able to point to and say the company kept their word, and they all feel like welcome changes. There's also a few promises that feel far more vague and less tangible, like the ever-present, long-running promise to "improve File Explorer". I feel like Microsoft's been promising to fix their horrible file manager for years now, without much to show for it, so I hope this time will be different. The company also wants to improve Widgets, the Windows Insider Program, and the Feedback Hub application. These all feel less tangible, and will be harder to quantify and benchmark. Beyond these first round of improvements that we're supposed to be seeing over the coming two months, Microsoft also promises to implement wider improvements across the board, with the usual suspects like better performance, quicker application launches, improved reliability, lower memory usage, and so on. They also promise to move more core Windows user interface components to WinUI 3, including the Start menu, which is currently written in React. Windows Search is another common pain point among Windows users, and here, Microsoft promises to improve its performance and clearly separate local from online results (but no word on making search exclusively local). There's some more details in the blog post, but overall, it sounds great. However, words without actions are about as meaningful as a White House statement on the war with Iran, so seeing is believing.

When Google said they were going to require verification from every single Android developer that would end the ability to install applications from outside of the Play Store (commonly wrongfully referred to as "sideloading"), it caused quite a backlash. The company then backtracked a little bit, and said they would come up with an "advanced flow" to make sure installing applications from outside of the Play Store remained possible. Well, Google has detailed this "advanced flow", and as everyone expected, it's such a massive list of onerous hoops to jump through they might as well just lock Android down to the Play Store and get it over with. First, if a developer is verified, you can download their applications to your device and install them the same way you can do now. Second, developers with "limited distribution accounts", such as students or hobby projects, can share their applications with up to 20 devices without verification. Third, and this is where the fun starts, we have unverified developers - basically what all Android developers sharing applications outside of the Play Store are now. Here's the full "advanced flow" as described by Google to allow you to install an application from an unverified developer: Setting aside the fact that developer verification is, in and of itself, a massive problem, I'm kind of okay with a few scary warnings, a disclaimer, and perhaps a single reboot to enable installing applications outside of the Play Store - a few things to make normal people shrug their shoulders and not bother. However, adding enabling developer mode and a goddamn 24-hour waiting period is batshit insanity, and clearly has the intention of discouraging everyone, effectively locking Android to the Play Store. Android is already basically an entirely locked-down, closed-source platform, and once this "advanced flow" comes into force, there's virtually no difference between iOS and Android, especially for us Europeans who get similarly onerous anti-user nonsense when trying to install alternative application stores on iOS. I see no reason to buy Android over iOS at this point - might as well get the faster phone with better update support.

What happens if you make a Linux syscall in a Windows application? So yeah, you can make Linux syscalls from Windows programs, as long as they're running under Wine. Totally useless, but the fact that such a Frankenstein monster of a program could exist is funny to me. ↫ nicebyte at gpfault.net The fact that this works is both surprising and unsurprising at the same time.

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.

In the recent blog post on the work funded by Sovereign Tech Fund (STF), we provided an overview of the "File Hierarchy for the Verification of OS Artifacts" (VOA) and the voa project as its reference implementation. VOA is a generic framework for verifying any kind of distribution artifacts (i.e. files) using arbitrary signature verification technologies. The voa CLI ⌨️ The voa project offers the voa(1) command line interface (CLI) which makes use of the voa(5) configuration file format for technology backends. It is recommended to read the respective man pages to get …
