Ah, my bad then.
- Comment on Test of a prototype quantum internet runs under New York City for half a month 2 months ago:
… 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).
- Comment on Test of a prototype quantum internet runs under New York City for half a month 2 months ago:
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)
- Comment on Im counting the days for a Piefed app so i can switch over and be able to forget about ml drama and weirdness 3 months ago:
“The transgender topic” is already weird as a statement (kinda like “the gay agenda”, it comes off as only considering it as a political statement?), and “clearly promoted by the bourgeoisie” implies it’s bad.
“Gas far as […] lgbt flags on government buildings”: it’s… not far at all? Again, weird statement.
“Biological male” is both wrong for the boxer (she’s cis) and generally used for transphobia (trans women on HRT aren’t biological males by any reasonable definition). It’s also generally conspiratorial.
Overall it’s not explicitly transphobic or bad, but it shows at minimum a very misinformed perspective.

How do you know how much of the disc is used?
- Comment on Microsoft wants to hide the 'Sign out' button in Windows 11 behind a Microsoft 365 ad 7 months ago:
Fair. Powertoys is really extensive. I quite like Pop (or gnome’s? Not sure) tiling window manager though.
- Comment on Microsoft wants to hide the 'Sign out' button in Windows 11 behind a Microsoft 365 ad 7 months ago:
PopOS’s COSMIC menu is like that I think (you can search files, the web, even stuff like turning volume up and down)? But I’ve never tried to run it outside of PopOS.
- Comment on The next Cortana: Copilot on Windows is no reason to buy a new PC 7 months ago:
You’re totally right. I started reading the article, got distracted, and thought I’d already read it. I agree with you then.
I still don’t trust Microsoft to not phone all your inputs home though.
- Comment on The next Cortana: Copilot on Windows is no reason to buy a new PC 7 months ago:
I don’t think Windows’ Copilot is locally processed? Could very well be wrong but I thought it was GPT-4 which is absurd to run locally.
- Comment on TransTerm: A terminal based youtube to mp3, wav and transcriber with a nice TUI (giving back to the community) 10 months ago:
For the screenshot you might want to use a terminal that doesn’t have bloom, a CRT filter, and a background, I genuinely can’t see the TUI.
- Comment on Hyperloop One to Shut Down After Failing to Reinvent Transit 11 months ago:
Lol I didn’t get the reference before
(There was a post about Switzerland considering legalizing cocaine cus they have so much and it’s so pure & common, apparently)
- Comment on Hyperloop One to Shut Down After Failing to Reinvent Transit 11 months ago:
Uh. Buddy. They absolutely are known for building a shitload of trains. There’s the Gottard, which is the longest tunnel through a mountain, and I think also the steepest railtracks in the world?
You’ve never heard of swiss trains always being on time?
- Comment on Study finds that Chat GPT will cheat when given the opportunity and lie to cover it up later. 11 months ago:
Neural networks are named like that because they’re based on a model of neurons from the 50s, which was then adapted further to work better with computers (so it doesn’t resemble the model much anymore anyway). A more accurate term is Multi-Layer Perceptron.
We now know this model is… effectively completely wrong.
Additionally, the main part (or glue, really) of LLMs is not even an MLP, but a “self-attention” layer. You can’t say LLMs work like a brain, because they don’t. The rest is debatable but it’s important to remember that there are billions of dollars of value in selling the dream of conscious AI.
- Comment on OpenAI was working on advanced model so powerful it alarmed staff 11 months ago:
Nah. Programming is… really hard to automate, and machine learning more so. The actual programming for it is pretty straightforward, but to make anything useful you need to get training data, clean it, and design a structure, which is much too general for an LLM.
- Comment on Results of the "Can you tell which images are AI generated?" survey 1 year ago:
Yeah, but the bridge is correctly over the river and the buildings aren’t really merged. Tough though.
The second one got me tho
- Comment on [Survey] Can you tell which images are AI generated? 1 year ago:
Sure, it’s not proof, but it gives a good starting point. Non-overfitted images would still have this effect (to a lesser extent), and this would never happen to a human. And it’s not like the prompts were the image labels, the model just decided to use the stock image as a template (obvious in the case with the painting).
- Comment on [Survey] Can you tell which images are AI generated? 1 year ago:
Personally, I have no issue with models made from stuff obtained with explicit consent. Otherwise you’re just exploiting labor without consent.
(Also if you’re just making random images for yourself, w/e)
((Also also, text models are a separate debate and imo much worse considering they’re literally misinformation generators))
Note: if anybody wants to reply with “actually AI models learn like people so it’s fine”, please don’t. No they don’t. Bugger off. arxiv.org/pdf/2212.03860.pdf here have a source.
- Comment on Server box just died, recommendations for a new one? 1 year ago:
To be honest, I don’t think it’s worth the bother. This is just an i3-5 something, and I got all the working parts off of it. But it’s good a good idea, thanks!
- Comment on Server box just died, recommendations for a new one? 1 year ago:
Well, I fully disassembled it, and I’ve found some components that are heating up a lot and probably making the buzzing noise.
However I have no idea what they are, if they’re the problem or some connected component. The label doesn’t return anything, so I think this 'uns a goner :(
- Comment on Server box just died, recommendations for a new one? 1 year ago:
Thank you! I’m not gonna try and fix the box itself, but somebody suggested it might be the power supply.
- Comment on Server box just died, recommendations for a new one? 1 year ago:
I… don’t know why I didn’t think of that. I’ll have to check if I have another.
- Comment on Server box just died, recommendations for a new one? 1 year ago:
Yes, it’s laptop RAM
- Comment on Server box just died, recommendations for a new one? 1 year ago:
I got this one for free because a company couldn’t be bothered to reinstall windows

… which is maybe why things that are essentially critical to a developed country’s lifestyle probably shouldn’t simply be companies. If we go off of “it’s not profitable”, public transport wouldn’t be any good, postal services would suck, etc.
The internet should be a public service like mail.
Also, in the US they paid the ISPs to hook everyone up to fiber, and then they just… didn’t.
- Comment on Striking actor Stephen Fry says his voice was stolen from the Harry Potter audiobooks and replicated by AI 1 year ago:
Uh no people definitely did. Mostly the people that actually knew how this shit worked. But even laypeople complained when it was just Dall-E and Midjourney.
- Comment on ChatGPT Has Liberal Bias, Say Researchers 1 year ago:
Mhm, but with the way LLMs work, it’s not possible to actually remove bias since it’s baked into the training data. Any adjustment towards “neutral” would be biased by what the adjuster considers neutral.
