3D printed spring, magnet, hall effect sensor by the looks of it.

That video is very annoying and doesn't in any way replace just having a screenshot of it running.

Yeah I’ve had one, still do, it never gets used because it’s a project car. Compared with one button press and coming back to a print in a few hours, it’s a constant nightmare of debugging, print issues, and manually changing filaments that

I’ve been running mine offline for years, I don’t know why other people haven’t been. They’re the only competent and reliable printer that isn’t a project car in itself, but they’re obviously not completely trustworthy. Easily fixed with an

Seems a little pointless, your keys can't be stolen but they can be instantly used by malware to persist across anything you have access to. The keys don't have any value in their own right, the access they provide does.

More or less, no desktop OS other than Qubes and MacOS (to a very limited extent) can handle the user being even vaguely compromised, much less a user with privilege. Keys to the kingdom are already in the user domain, SSH keys, all your em

Intentionally interfering with 911 would probably be a poor decision.

The ones you hear about are caught quickly, I’m more worried about the non obvious ones. So far none of these have been as simple as changing a true to a false and bypassing all auth for all products or something, and would that be caught b

The language matters, but your original guess was actually correct, you can do tricks with sha256 where you only end up calculating a fraction of the total double hash in order to get a pass or fail. Modern bitcoin miners do a double sha256

Yes, Anubis is just non standard and obscure, the proof of work bit is completely irrelevant (except for getting people on their phone to not visit your website).

Anybody can prompt Claude to implement this, which was my point, it doesn't stop bots because a bot can literally write the bypass! My prompt was the proof of work function from the repository, asked it to make an implementation in C t

It doesn't matter if your hottest loop is using string comparisons, as another poster pointed out in C you aren't even doing the majority of the second hash because you know the result (or enough of it) before finishing it. The Ja

Bravo, you even implemented the midstate speedup from Bitcoin, that's way more impressive.

Ironically I used a LLM to write a bypass for this ridiculous tool, doing hashing in a browser makes no sense, Claude's very bad implementation of it in C does tens of megahash a second and passes all of the challenges nearly instantly

That's a bit surprising to me, wonder what the root cause of that was. It seems to be shared across multiple products at once so maybe they had a bad batch of cells?

I've never had any issues with brand name, not dollar store power banks and I've been using them for more than a decade. I'd totally expect a $5 pink power bank from a alphabet amazon seller to be an issue, but anything moder

That's a kind of meaningless comparison. Peanuts are about 8kJ per gram supposedly, by your measure we should ban even small amounts of peanuts on planes because 100 grams of them contain more energy than a hand grenade. Without talkin

My first ever programming was with the original brick, I made a scanner with the light sensor and a terrible python script that took the values from the serial port and turned them into a bitmap.

I occasionally saw a readme with a couple of Emoji in it, but the behavior where every title, every bullet point, every sentence ends with one or more of them is utterly obnoxious. There's something about the sources that chatGPT uses

That’s not really correct, modern color eink displays actually change color, there’s different pigments inside each cell and others are created visually using dithering. Only the older type are monochrome displays with a color filter behave

They’re Sharp memory displays, functionally LCDs but with memory for retention under each pixel. They are not and have never been eink.

They more or less have colored particles hanging around in goop and those get pushed around within a small sealed cell by electrostatic charges, there’s presumably some fundamental limit on the total quantity of the colored particles within
