… what you said is correct, but that’s superposition, not entanglement. Entanglement is when you create a product state of several qubits that cannot be decomposed into a tensor product of basic states (a single proton/photon/whatever).

Oh yeah, that. My bad, mixed 'em up.
The original algorithm doesn’t use entanglement, though! Just the fact that measurements can change the state. You can pick an axis to measure a quantum state in. If you pick two axes that are diagonal to each other, measuring a state in the “wrong” axis can give a random result (the first time), whereas the “right” one always gives the original data.
So the trick is to have the sender encode their bits into a randomly-picked axis per bit (the quantum states), send the states over, and then the receiver decodes them along a random axis as well. On average, half the axes will match up and those bits will correspond. The other bits are junk (random). They then tell each other the random axes they picked, which identifies the right bits!
They can compare a certain amount of their “correct” bits: if there’s an eavesdropper, they must have measured in the wrong state half the time (on average). Measurement changes the state into its own axis, so the receiver gets a random bit instead of the right one half the time. 25% of the time, the bits mismatch, when they should always correspond.
You can have post-quantum cryptography using classical computation, though
(“Simply” pick a problem with no quantum acceleration. I think Elliptic Curves Cryptography works, but I’m not an expert)
Neat! I can’t wait for Cosmic, it’s shaping up to be so nice
Very nice! Does/will cosmic have the ability to style buttons? Those are the main factorio UI feature imo (that and so many slots, which aren’t a normal UI element)
Ahh, that makes sense. Powers of two are real convenient. Your math is a little wrong though: X != (X & 0xFF) + (X >> 8), but X = (X & 0xFF) + (X >> 8) << 8
The right half can be removed entirely if you’re doing modulo 16, since the first 4 bits will always be 0. So it simply becomes X & 15
! Much cleaner for sure.
Would you happen to remember what the optimization was, mathematically?
https://stackoverflow.com/questions/20036698/subdivide-a-modulo-function-16-bit-but-can-only-do-8-bits-at-a-time#20036828 seems to say that it’s “impossible afaik”, and I can’t seem to optimize it myself (though this kind of math isn’t my forte)
Block the community?
I’m not an OS dev, I have no idea how stuff this low-level works.
I’d suggest some kind of “press this key to view debug information” text (or make it documented but not visible, to avoid people just pressing whatever button is written on the screen)
Last one is the only one I actually got (and MHA actually). It’s animal crossing. Edit: Oh! Second to last is Artemis Fowl

I’ll stick with AP for now but I’ll keep an eye on it, then.
Nostr is culturally vaguely american, and it’s hard to distinguish the libertarians from the Trumpists there (I’ve seen several posts saying “Trump will be better for Bitcoin”, for example). Libertarians and republicans both sell themselves as “small government”.
“Leftist libertarians” generally call themselves anarchists, in my experience.
I checked out Nostr relatively recently and it seemed to me it was full of cryptobros and extremely right-wing people (libertarians, Trump fanatics. A ton of racism and queerphobia, also a bunch of conspiracy thinking). Has anything changed?
Out of curiosity, I looked up the numbers. This is correct, they make 9.2 billion per quarter from ads and 10.7 billion from subscriptions. I can’t find expenses per-segment, but in 2023 their total “Cost of revenues” was 37 billion. I doubt everything other than youtube costs less than 17 billion, so they’re definitely making a profit.

This applies to at least NewPipe and yt-dlp, probably basically every such tool. Also, if you use logged-in cookies and download, they sometimes ban your account! Fun!

Ah, my bad then.
