The Y2K Bug In BSD 2.11 That Survived 2000

June 15, 2026 by No comments

A year before the arrival of the brand-new 21st millennium, the Year 2000 Bug was predicted to grind modern society to a halt and ensure that at the dawn of the year 2001, there’d be nothing left but the smoldering wreck of once great societies. Thanks to the concerted efforts of countless engineers, software developers, and many others, we were left with mostly just silly glitches, with one of these surviving bugs apparently just discovered, as [Van Heusden] reported on an NTPd bug in BSD 2.11.

To be fair, it is a pretty obscure one, as the demonstration involves BSD 2.11 on a PDP-11/70 from 1975, so it’s probably not something that still sees much use outside retrocomputing enthusiast circles. In the blog post, the demonstration involves connecting a specific adapter by Traconex, capable of receiving WWV/WWVH time signals, and setting it up for use by the NTPd prior to running the ntpd -a any -d -d -d -d command.

IKEA Storage Box Just Happens To Make Great Printer Cover

June 14, 2026 by 1 Comment

The Snapmaker U1 3D printer is an impressive machine for the price, but [Beaver Works] found the optional factory-offered top cover a wee bit expensive for his tastes. The solution? 3D print a fixture and use a clear 45 L Samla storage box from IKEA as an effective and affordable cover for the machine.

Why a cover?  A cover helps retain heat and block drafts, which can help improve print quality. A cover also keeps the machine’s insides dust and debris-free, not to mention serving as a decent barrier to curious fingers or paws.

This is a great use of an off-the-shelf product that performs at least as well as any bespoke solution. The nature of printer enclosures makes them trickier than one might think, with the size and weight of materials often driving costs up for something that seems relatively simple in concept. Getting one by 3D printing the fixtures and purchasing the bulky part locally and affordably is a great alternative. IKEA even sells the box’s lid separately, so one can buy just the box and isn’t stuck with an unused lid afterward.

Integrating off-the-shelf components into a design is often risky because much of it is outside the designer’s control. Availability can change, and a manufacturer might alter dimensions or design elements without any notice. But IKEA’s storage products are pretty well standardized and work really well for this purpose.

On the off chance you need a design tweak, [Beaver Works] has provided STEP files for the 3D-printed parts, something we always love to see.

Building Your Own X-Ray Detector Screen

June 14, 2026 by No comments

Fluoroscopy is probably the best-known method of X-ray imaging: an X-ray beam passes through the subject to be imaged, and the transmitted X-rays illuminate a phosphor screen. Dense objects, such as metal or bone, cast a shadow on the screen, which provides a real-time image of the subject’s interior. Already having access to X-ray sources, [MarcellF]’s next step was to investigate common phosphor materials, then synthesize his own.

Most common materials that fluoresce under ultraviolet light showed no activity under X-rays: fluorescein, quinine, UV fluorescent paint, and common fluorescent minerals emitted no noticeable glow under 80 kV X-ray stimulation. However, strontium aluminate phosphors did fluoresce well, with a strong afterglow, as did the phosphors in a fluorescent light bulb, some LEDs, and an electroluminescent panel. The electroluminescent panel, which used a zinc sulfide phosphor, was almost as bright as the gadolinium oxysulfide screen from a CT scanner’s detector and had no noticeable afterglow.

Hackaday Links: June 14, 2026

Times are tough out there, and many are starting to feel the pressure at the grocery store checkout line or the gas pump. But whenever you start to worry about affording life’s necessities, take comfort in the knowledge that somebody is so flush with cash that on Friday they decided to treat themselves and spend $3 million for a sealed copy of Super Mario Bros for the Nintendo Entertainment System.

Although we’re not going to say it necessarily justifies the insane price — a new record for the most ever paid for a video game, incidentally — Heritage Auctions does note in their press release that this is an exceptionally rare version of what’s admittedly one of the most iconic pieces of software ever produced. This is only one of three copies of this particular variant known to exist, which Nintendo apparently distributed to test markets in the United States ahead of the game’s official 1985 release.

In slightly more modern gaming news, Asha Sharma, the new head of Microsoft’s Xbox division, has been making some big swings to try and get Microsoft’s gaming division back on track after years of declining sales. As part of that effort, she recently penned an article detailing some of the challenges the company is facing, which includes some interesting hardware details.

According to the blog post, she claims that in February, the cost of memory and storage components for the Xbox console had doubled compared to the previous year. But those numbers have jumped again, and by the time the holidays roll around, she expects they’ll be paying five times what they did in 2024. That’s bad news for anyone looking to put an Xbox under the tree come Christmas, but even worse news as the company works on the console’s successor. Considering that today’s hardware from Sony and Microsoft can already set you back $700 USD depending on which version you get, it seems like we’re approaching a point where gaming consoles could price themselves out of the market.

Bavarian Court Tells Gemini It Can’t Be A Real Boy Until It Tells The Truth

June 14, 2026 by 37 Comments

Does anyone like Google’s AI summaries? If so, they weren’t on the Judge’s bench in a specific Bavarian courtroom recently, where it was ruled that yes, Google is liable for the hallucinations of its search engine AI.

This was a civil case brought by a pair of Munich companies, both of whom were wrongfully slandered by LLM hallucinations. Google took the position that this information must have existed somewhere, and like presenting links to libelous websites — something they have no obligation to avoid — they should not be held accountable for what the summary at the top of the search results says.

Why Not Yserver? It’s Xserver, But Rust-y.

June 14, 2026 by 17 Comments

If you’re not into Wayland as a display manager, it seems like your options are slowly dwindling. Xorg isn’t exactly a hotbed of activity, and the one fork everyone knows about is best known as a political lightning rod. Luckily, Rust developers can apparently never see a tool without pulling it into their heavily oxidized bucket of crabs, so we now have another option: the creatively named yserver, released under the MIT license by [joske].

The name, yserver, for the record, is just a placeholder name, but we rather like the simple logic of “Y comes after X” — sure, you could call it X12, but that could imply continuity, and this is a clean break. It’s also not a full reimplementation of the huge, sprawling mess that Xorg has become over the decades. It can’t launch multiple screens and thus lacks full multi-monitor support. So, for now, it may be too bare-bones for some people’s use cases.

As it uses Vulkan, it is limited to relatively modern hardware, but has been tested on Intel, AMD, Nvidia, and Apple chips. The target kernel is good old Linux, but the docs do cover compiling for FreeBSD; just be aware that that’s very much a secondary target. FreeBSD users are probably used to that, though.

On Linux, a standalone DRM/KMS yserver can successfully run not just window managers but full desktops — specifically MATE, Cinnamon, and XFCE, as they’re not on the Wayland bandwagon. It even supports Compiz, in case you missed the cube and wiggly window animations. You can also use yserver via Xwayland or even Xorg. Speaking of Xorg, [joske] has run the X.Org X Test Suite (xts5) against this proposed successor, and it currently scores 66.2%, which seems pretty good considering the project explicitly does not plan to copy all of Xorg’s functionality.

Aside from multiple screens, one thing that would have been neat to see is support for the Asterinas rust-based Linux-compatible kernel — though if that project achieves full Linux compatibility, that may be a non-issue. Even if you aren’t an oxidization enthusiast, you might find reasons to be happy to see more competition in the display-manager market — after all, Wayland Will Never Be Ready For Every X11 User. If Xorg really is destined to the slow death critics predict, perhaps yserver could cover the holdouts.

OpenCAL: Computed Axial Lithographic 3D Printing For Everyone

June 14, 2026 by 10 Comments

Computed Axial Lithographic printing gets even closer to the Star Trek replicator fantasy than any other 3D printer we’ve seen: there’s a machine, it glows with a mysterious bluish light, and an object appears. OK, the object is appearing inside a spinning vat of photochemical ooze, not in thin air, but that’s a detail. It’s still very cool tech, and now it’s open source enough to replicate with full documentation and a GitHub repository.

This project is descended from the same Berkeley research that we featured last year, but at that point, they were inviting everyone to join their Discord server, and that was about it. At the time, we put on our old man outfit to yell at clouds and say, “A Discord shouldn’t count as open source!” For once, it looks like those geriatric grumblings were heeded. There is still a corporate-hosted chat server named for a malignant goddess, and you’re still invited, but now there’s also actual, searchable documentation!
