Re:Olo (Color) on Tuesday August 18, 2026 @02:39PM (#49350484)
I don't get it. Is it saying Olo is an example of a color that can't be displayed on modern RGB displays?

I wonder if someone could sell pieces of paper which have this color?

In addition to holding the key, wouldn't you additionally need to know exactly which model to check against? So for passive detection to happen, I think each company would need to check every message against every model version? Also would need to spend resources re-invoking the each model version against each message.

Ok but how often do people provide a proof assistant verified proof for it? That's what this is. (Except that it's because the verifier had a bug.)

Gilbert Strang has an excellent free (IIRC) linear algebra course, accompanied by his excellent textbook. Kahn Academy has some surprisingly good linear algebra lectures as well, if something isn't clicking.

I'm not buying that "I am over 18, but I tell you this without revealing that I am over 18" is a real thing

Is there a name for this? I think about this all the time. I've always had a theory that some offensive words may actually be persisting longer solely because we essentially calcify their definitions and never allow them to evolve into new less offensive meanings.

Re:NixOS 25.11 Released on Monday December 01, 2025 @01:08AM (#46104060)
No, but I can empathize. I never understood the Nix language. It's impenetrable to me. I hate it so much.

I keep checking back every year or so secretly hoping they'll have upgraded the language. It's fascinating how successful Nix is given how utterly opaque the language is.

Imagine how hard moderating a forum is. Now imagine moderating the whole Internet. Everyone always thinks it's trivial. Everyone couldn't be more wrong.

> A sound that could not possibly be produced by the circuit in the PDF or any reasonable variation of the circuit.

Why not? What's wrong with the circuit?

Here's my rebuttal to your claim: I literally show a circuit of a single wire and say I'm using it on my guitar, and I could get that sound. Why? Because I didn't say I'm _only_ using the wire. I have other equipment.

> The whole thing has the feel of long AI hallucination for a vague prompt.

I really doubt the video itself is AI. Only because it doesn't need to be. It's literally just a dude sitting and talking to a camera. It would be easier to make this video than to generate it with AI.

> I can’t think of any reasonable explanation for why these videos exist or for how they were made.

Respectfully , that's a bit of a ridiculous thing to say. I'm not sure where you're going with it. Even if this was 100% AI, there would _still_ be a reason someone took the time to generate it and post it. Why does any YouTuber post a video?

> It seems completely possible that, in 3 or 4 years time, publicly available AI services will be able to produce videos of this quality and duration.

I think you're completely correct, and I think many of us share your paranoia here. But honestly, there are _plenty_ of better examples of AI slop out there, and it's sort of ironic that you've chosen to focus on one that very much doesn't appear to have any signs of AI.

Re:Banana Powered Guitar Pedal on Saturday October 18, 2025 @03:42PM (#45629886)
You seem convinced this is "fake". It's unclear what you think is fake about this.

Fruits are wet, salty, acidic objects. As such, they can be used in an electronic circuit. They have an impedance, and, if you do it right, a voltage. [1] There's nothing fake or surprising about this.

He's just placing the fruit in series with the power source of some effect pedal. Unsurprisingly, this slightly alters the power source for the pedal, creating an audible difference in effect.

It's probably not something someone would do in practice, but notably, when it comes to electric guitars, experimenting with different types of distortion is pretty common, and it's common for guitar players to get creative.

Even if this "fruit effect" is not practical (I mean, you'd get inconsistent results), it's definitely a silly and interesting enough idea to justify a YouTube video. I could even see someone using it as a gimmick for playing live.

> I think anyone with a basic understanding of electronics would see the absurdity of these circuits and wouldn’t buy the schematics

Which schematics are you referring to? I think you might be assuming he's selling the "fruit" circuit. I think he's selling circuits for effect pedals, completely independently of this "fruit" video.

No shade intended, but a philosophical conversation is unconstructive when it centers around highly ambiguous and undefined words. The word "real" does not actually have a general meaning until you give it a definition in support of your comment. (And surely you will find that if you had a definition, you would not need so much "belief" to back up your argument.)
