Escaping US Tech Giants Leads European YouTuber To Open Source

May 17, 2025 by Tyler August 113 Comments

The video (embedded below) by [TechAltar] is titled “1 Month without US tech giants“, but it could have been titled “1 Month with Open Source Tools” — because, as it turns out, once you get out of the ecosystem set up by the US tech giants, you’re into the world of open source software (OSS) whether you want to be or not.

From a (German-made) Tuxedo laptop running their own Linux distro to a Fairphone with e/OS (which is French), an open version of Android, [TechAlter] is very keen to point out whenever Europeans are involved, which is how we learned that KDE has a physical headquarters, and that it’s in Berlin. Who knew?

He also gives his experiences with NextCloud (also German), can be used as an OSS alternative Google Workspaces that we’ve written about before, but then admits that he was the sole user on his instance. To which one must question: if you’re the sole user, why do you need a cloud-based collaborative environment? To try it out before getting collaborators involved, presumably.

Regardless what you think of the politics motivating this video, it’s great to see open source getting greater traction. While [TechAltar] was looking for European alternatives, part of the glory of open source is that it doesn’t matter where you’re from, you can still contribute. (Unless you’re Russian.) Have you found yourself using more open source software (or hardware) of late? Do you think the current political climate could lead to a broadening of its reach? Is this the year of the linux desktop? Let us know what you think in the comments. Continue reading “Escaping US Tech Giants Leads European YouTuber To Open Source” →

RTEMS Statement Deepens Libogc License Controversy

May 14, 2025 by Tom Nardi 41 Comments

Earlier this month we covered the brewing controversy over libogc, the community-developed C library that functions as the backbone for GameCube and Wii homebrew software. Questions about how much of the library was based on leaked information from Nintendo had been circulating for decades, but the more recent accusations that libogc included code from other open source projects without proper attribution brought the debate to a head — ultimately leading Wii Homebrew Channel developer Hector Martin to archive the popular project and use its README as a central point to collect evidence against libogc and its developers.

At the time, most of the claims had to do with code being taken from the Real-Time Executive for Multiprocessor Systems (RTEMS) project. Martin and others in the community had performed their own investigations, and found some striking similarities between the two codebases. A developer familiar with both projects went so far as to say that as much as half the code in libogc was actually lifted from RTEMS and obfuscated so as to appear as original work.

While some of these claims included compelling evidence, they were still nothing more than accusations. For their part, the libogc team denied any wrongdoing. Contributors to the project explained that any resemblance between libogc code and that of either leaked Nintendo libraries or other open source projects was merely superficial, and the unavoidable result of developing for a constrained system such as a game console.

But that all changed on May 6th, when the RTEMS team released an official statement on the subject. It turns out that they had been following the situation for some time, and had conducted their own audit of the libogc code. Their determination was that not only had RTEMS code been used without attribution, but that it appeared at least some code had also been copied verbatim from the Linux kernel — making the license dispute (and its solution) far more complex.

Move Over, Lithophane: 3D Printed 3D Photos With Gaussian Splats

May 10, 2025 by Tyler August 24 Comments

If you had asked us yesterday “How do you 3D Print a Photo”, we would have said “well, that’s easy, do a lithophane”– but artist, hacker and man with a very relaxing voice [Wyatt Roy] has a much more impressive answer: Gaussian splats, rendered in resin.

Gaussian splats are a 3D scanning technique aimed at replicating a visual rather than geometry, like the mesh-based 3D-scanning we usually see on Hackaday. Using photogrammetry, a point cloud is generated with an associated 3D Gaussian function describing the colour at that point. Blend these together, and you can get some very impressive photorealistic 3D environments. Of course, printing a Gaussian smear of colour isn’t trivial, which is where the hacking comes in.

Libogc Allegations Rock Wii Homebrew Community

May 1, 2025 by Tom Nardi 59 Comments

Historically, efforts to create original games and tools, port over open source emulators, and explore a game console’s hardware and software have been generally lumped together under the banner of “homebrew.” While not the intended outcome, it’s often the case that exploring a console in this manner unlocks methods to run pirated games. For example, if a bug is found in the system’s firmware that enables a clever developer to run “Hello World”, you can bet that the next thing somebody tries to write is a loader that exploits that same bug to play a ripped commercial game.

But for those who are passionate about being able to develop software for their favorite game consoles, and the developers who create the libraries and toolchains that make that possible, the line between homebrew and piracy is a critical boundary. The general belief has always been that keeping piracy at arm’s length made it less likely that the homebrew community would draw the ire of the console manufacturers.

As such, homebrew libraries and tools are held to a particularly high standard. Homebrew can only thrive if developed transparently, and every effort must be taken to avoid tainting the code with proprietary information or code. Any deviation could be the justification a company like Nintendo or Sony needs to swoop in.

Unfortunately, there are fears that covenant has been broken in light of multiple allegations of impropriety against the developers of libogc, the C library used by nearly all homebrew software for the Wii and GameCube. From potential license violations to uncomfortable questions about the origins of the project, there’s mounting evidence that calls the viability of the library into question. Some of these allegations, if true, would effectively mean the distribution and use of the vast majority of community-developed software for both consoles is now illegal.

A Tale Of Nuclear Shenanigans From Down Under

April 6, 2025 by Jenny List 47 Comments

It’s likely that among the readers of this article there will be many who collect something. Whether it’s rare early LEDs or first-year-of-manufacture microprocessors, you’ll scour the internet to find them, and eagerly await mystery packages from the other side of the world.

There’s a tale emerging from Australia featuring just such a collector, whose collection now has him facing a jail sentence for importing plutonium. The story however is not so clear-cut, featuring a media frenzy and over-reaction from the authorities worthy of Gatwick Airport. [Explosions&Fire] has a rather long video unpacking the events, which we’ve placed below the break.

Emmanuel Lidden is an element collector, someone who tries to assemble an entire Periodic Table in their collection. He ordered a range of elements from an American element collectors’ supply website, including samples of plutonium and thorium. He seems to have been unaware he was committing any crime, with the microscopic samples available from legitimate websites with no warnings attached. The case becomes murkier as the Australian authorities flagged the thorium sample and instructed the courier not to deliver it, which they did anyway. Then a raid of the type you’d expect for the terrorists who stole the plutonium in Back To The Future was launched, along with that Gatwick-esque media frenzy.

We’re inclined to agree that the penalty likely to be meted out to him for buying a sliver of a Soviet smoke detector embedded in a Lucite cube seems overly steep, but at the same time his obvious naivety over dealing in radioactive materials marks him as perhaps more than a little foolhardy. It’s something over which to ponder though, have we managed to amass anything illegal disguised as outdated devices? Have you? Perhaps it’s something to discuss in the comments.

The Everlasting Hunt For The Loch Ness Monster

April 1, 2025 by Jenny List 8 Comments

When a Loch Ness Monster story appears at the start of April, it pays to check the date on the article just to avoid red faces. But there should be no hoax with this one published on the last day of March, scientists from the UK’s National Oceanography Centre were conducting underwater robotics tests in Scotland’s Loch Ness, and stumbled upon a camera trap lost by Nessie-hunters in the 1970s. Just to put the cherry on the cake of a perfect news story, the submarine in question is the famous “Boaty McBoatface”, so named as a consolation after the British Antarctic Survey refused to apply the name to their new ship when it won an online competition.

The Most Extreme Instamatic in The World

An NOC scientist holds the camera in its container — Sadly the NOC haven’t released close-ups of the inner workings of the device.

The camera trap has survived five decades underwater thanks to a sturdy glass housing, and appears to be quite an ingenious device. A humble Kodak Instamatic camera with a 126 film and a flash bulb is triggered and has its film advanced by a clockwork mechanism, in turn operated by a bait line. Presumably because of the four flash bulbs in the Kodak’s flash cube, it’s reported that it could capture four images. The constant low temperature at the bottom of a very deep loch provided the perfect place to store exposed film, and they have even been able to recover some pictures. Sadly none of then contain a snap of Nessie posing for the camera.

Hackaday Links: March 30, 2025

March 30, 2025 by Dan Maloney 11 Comments

The hits just keep coming for the International Space Station (ISS), literally in the case of a resupply mission scheduled for June that is now scrubbed thanks to a heavy equipment incident that damaged the cargo spacecraft. The shipping container for the Cygnus automated cargo ship NG-22 apparently picked up some damage in transit from Northrop Grumman’s Redondo Beach plant in Los Angeles to Florida. Engineers inspected the Cygnus and found that whatever had damaged the container had also damaged the spacecraft, leading to the June mission’s scrub.

Mission controllers are hopeful that NG-22 can be patched up enough for a future resupply mission, but that doesn’t help the ISS right now, which is said to be running low on consumables. To fix that, the next scheduled resupply mission, a SpaceX Cargo Dragon slated for an April launch, will be modified to include more food and consumables for the ISS crew. That’s great, but it might raise another problem: garbage. Unlike the reusable Cargo Dragons, the Cygnus cargo modules are expendable, which makes them a great way to dispose of the trash produced by the ISS crew since everything just burns up on reentry. The earliest a Cygnus is scheduled to dock at the ISS again is sometime in this autumn, meaning it might be a long, stinky summer for the crew.
