Photocopiers and printers have included anti-counterfeiting tech for decades, so there is precedent for this kind of thing. And this is addressing a real growing problem: https://www.cbsnews.com/sanfrancisco/news/santa-rosa-167-gun... https://da.santaclaracounty.gov/da-task-force-seizes-ghost-g... https://www.vvng.com/3d-printed-firearm-recovered-after-man-...

But money counterfeiting is a different proposition: the printer is blocking exactly known patterns found on real currency. In fact, many bill designs incorporate patterns that are easily machine detectable for this purpose.

Blocking the printing of parts of mechanisms is a completely different beast, because the functionality is only discernible after final assembly of the individual parts, which can be shaped in a variety of ways. Most of these parts are unique to guns or at least usable in other kinds of designs. E.g. the same trigger lever design could be used for a ghost gun or a nerf gun or a water pistol. So where would yiu draw the line of all the classifier sees is G code that combines support structures, the actual surfaces and infill of some arbitrary collection of parts?

I'm against guns in generally, but this classification problem seems particularly ill posed and I don't want it to result in tamper-resistant printers stopping people from tinkering and taking the fun out of printing. The US should just outlaw the casual carrying of guns of individuals in public. That's not a violation of the second amendment.

Based on the fact that Claude Opus 4.8 decided I needed a cybersecurity exemption to debug a stupid pure virtual call bug (basically virtual method called inside of destructor) that I had already found, oh boy, I sure would love to have my 3D prints analyzed by Anthropic safe guards. We should also ensure that nothing shaped like a dildo can be printed without scanning our face and genitalia and keeping it on file wi…

I'm getting a lot of refusals these days from multiple LLMs on multiple fronts for silly stuff, a lot more than I had for a while. If this is where things are really going, I think open weight models have a big future.

I tried to photo copy a dollar bill when I was a kid on a dinky inkjet printer. It printed half way then spit out something about counterfeit prevention. I scanned the bill, printed the top half, fed the paper back in, and printed the bottom half. This can only actually stop the completely unmotivated.

You managed to defeat the first layer of defense - the warning. The yellow identifying dots were present on your printed copy, should you have decided become a precocious criminal successful enough to warrant the attention of the Secret Service.

Why does California since Arnold left office feel the need to regulate above the average other states regulate? [in fairness gov Brown would veto some of the crazier ideas that arrived at his desk] Why do the pols feel like they have to pick fights in so many places? I doubt there’s a majority of voters who want this.

You think too highly of California voters.

All they have to do if frame it as an unnecessary freedom that only conservatives and wackos want to keep and they will 100% support it.

They see their state as a sort of oasis in the country and will do whatever it takes to keep the guns out. They really believe they’re just a few laws away from solving any issue a “reasonable” American could face.

> The required technology is not possible - 3D printers read code, not intent; they cannot tell what a shape is for. "Anthropic announces Project Disarm, a new model designed for 3d printer manufacturers to quickly infer whether the intent of an stl file is a weapon. The printer first submits the job to the cloud, and only after it's approved will it print." Not that I want this future, just that I can imagine it.

The future is almost certainly the terrible path: "applications phoning home to judge whether a use case is approved by the company." All writing is on the wall, and directionally that's the way software and hardware has been moving. We have unfortunately normalized the idea that users must have this ongoing tethered relationship to the product manufacturers and software developers, who measure, change, and control t…

Echoes of Network Neutrality problems, where BigCo is permitted to block or degrade sites about how to cancel your BigCo service.

If that becomes current law I don’t want to ever hear about Europe being over-regulated compared to the US…

There are several snarky knee-jerk reactions in the comments here, but state assemblies pass things all the time that ultimately fail to pass or get vetoed. Now the public will debate it, contact their state senators to give their opinions...it's all part of the process.

Here's a series of models, which of these is a gun part? https://imgur.com/a/p3UtJqW

Money anti-counterfeiting is trivial, it's just 5 dots arranged in a specific pattern. Deciding what is a gun part is impossible, even for an expert human.
