Question: do the Japanese actually care about privacy? I know I do, but if you were to ask a Japanese person why does their country use cash, would they say “We have considered a system of payment cards and decided against it for privacy reasons” or would they just shrug and say “I dunno, I’m not in charge of payment systems, I use what I have”?
The credit companies do not insure against fraud, they simply take the money out of the merchant account and put it back into yours. Now it’s the merchant who has no recourse, if they have already shipped the product. So the only difference between CC and crypto is who is typically left holding an empty bag in case of theft - the payer or the payee. Certainly not the banks!
I’d argue in terms of assigning responsibility, it seems more fair to expect you the customer to keep your digital wallet secure from thieves, than to expect the merchant to try guess every time whether the visitor to their online store happens to be using a stolen credit card.
I want people to be able to report bugs without any trouble.
Thank you for being aware! I’ve experienced this on github.com. I’ve tried to submit issues several times to open source projects, complete with proposed code to solve a bug, but github shadowbans my account 6 hours after creating it (because I use a VPN? a third-party email provider? do not provide a phone number? who knows). I can see the issue and pull request when logged in, but they only see a 404 on their project page even if I give them a direct link. I ended up sending them a screenshot of the issue page just to convince them this was even possible. Sad to hear gitlab does it even worse now by making phone mandatory.
Am I the only one for whom "open"subtitles.org hasn’t worked in years? I literally cannot find the download button, like in those okboomer memes. Never used the API. Switched to subscene.com and haven’t had problems since.
I use ProtonVPN for everything, and I’ve started noticing more and more sites simply blocking me if I try to connect to them through ProtonVPN. As much as it sucks, I’ve more or less become acclimated to having to deal with an increased number of captchas while using a VPN; but I’m pretty angry about being blocked...
Good question to ask, since specifics of selection process may affect the decision outcome! Other variants include growing humans in a vat from scratch on demand, using Star Trek transporter clones, or abducting the necessary number of people from a pre-selected list where your name happens to be the first one. For now, imagine the potential population as the 5 billion living cognizant adults.
as X approaches infinity, the difference becomes negligible
It may be negligible to the 4.999… billion adults sleeping comfortably and securely in their beds tonight, but the problem presupposed that you have already been abducted. It remains underdefined whether you refers to you the specific person reading this meme, or a more general you-the-unfortunate who has been chosen and is now listening to this on the headphones.
It’s a standard runaway trolley problem. The trolley is traveling down the main track unless the switch is flipped to send it down the side track. The lever is labeled such that there is no ambiguity which way it is set, the blindfolds notwithstanding. The villain is pernicious and will be equally (though not exceedingly so) delighted to see you die by your own action where inaction would have had saved you. You can somehow trust that the announcement in the headphones is true and not a lie. Such as, for example, you have seen this exact situation happen many times before on TV and survivors/witnesses have described the villain to be truthful every time.
You are on the side track in scenario A. You die if you pull. Ironically, you’d be killing yourself. The dice are to make the two scenarios not equally likely.
My guess is that no to the first, since I have a 1/3 chance of being in the forked path, vs 1/15 of being in the straight path and my lever being connected.
Suppose you live in a kingdom where everyone is as selfish as you, and you’ve seen on TV many situations exactly like this one where people were tied to the tracks - usually one at a time and occasionally 10 at a time. (The villain has been prolific.) You’ve seen them all follow this logic and choose not to flip their switch, yet out of ~1500 people you have seen in peril this way, ~1000 of them have died. If only their logic had convinced them (and you) otherwise, 1000 of them could have selfishly survived! Doesn’t seem very logical to follow a course of action that kills you more often than its opposite.
(If you don’t want to imagine a kingdom where everyone is selfish, you can imagine one where x% are selfish and (100-x)% are altruistic, or some other mixture maybe with y% of people who flip the lever randomly back and forth and z% who cannot even understand the question. The point is that the paradox still exists.)
Edit: I can see now how in a 100% altruistic kingdom, where you are the only selfish one and you know for sure that everyone else will logically altruistically pull the lever, it makes sense for you to not pull the lever. Presumably there is some population x% split (44% selfish/56% altruistic?) where your selfish decision will have to reverse. Weird to think that your estimate of the selfishness of the rest of the population has a relevance on your decision!
there’s no way to know which track the trolley is on
It’s a standard trolley meme problem, the trolley will keep going on the main track unless the lever is switched 😁. I thought !science_memes would be familiar with trolley problems, but I guess I get to introduce some of you! You might want to start off on some easier trolley memes first, this is advanced level stuff.
where the real lever sends it
There is not usually ambiguity with the lever. If you wish, you can have an announcement in the headphones “main track… side track…” every time you flip the lever. Your only uncertainty is which track you yourself are bound to, given how you’re blindfolded.
If 6 is rolled, then P(X|R=6) = (N-1 choose 9)/(N choose 10)
Might as well reduce that to 10/N to make the rest of the lines easier to read.
If you don’t flip it, you have a 2/3 chance of dying.
There is also a chance that your switch is not connected and someone else has control of the real one. So there is an implicit assumption that everyone else is equally logical as you and equally selfish/altruistic as you, such that whatever logic you use to arrive at a decision, they must have arrived at the same decision.
No matter what your goal is, given the information you have, flipping the switch is always the better choice.
That is my conclusion too! I was surprised to learn though in the comment thread with @pancake that the decision may be different depending on the percentage of altruism in the population. E.g. if you are the only selfish one in an altruistic society, you’d benefit from deliberately not flipping the switch. Being a selfish one in a selfish society reduces to the prisoner’s dilemma.
There was some scare in lemmy development circles recently about script injection vulnerabilities. The various apps and frontend developers “solved” the problem by peppering untrusted user input with escape sequences all over the place. User submits post? Escape title! Receive new post from a federated instance? Escape title!
Obviously if you escape the title twice and display once, it will show up weird. The problem is that the various devs haven’t agreed yet which parts of the messaging protocol are supposed to be already escaped and which are not. Ideally all user input should be stored and transmitted in raw form, and only escaped right before displaying. But due to various zealously-cautious devs we get this instead:

The recent post made me fear that a lot of you are taking this “monkey looks at double-slits” meme, which was only ever supposed to be a funny monkey meme, actually seriously.

They talk about how it was never actually possible to do this before, because it requires very fine “electron optics” and manufacturing of components, like slits and shutters, with nanometer precision. So while the thought experiment with electrons itself was proposed by Feynman in 1963 (which is probably what inspired the monkey meme and the like), it was not actually realized until 2019. I’m also now guessing that the electron quantum eraser paper from 2014 doesn’t use a double slit but some other electronic quantum circuit that is easier to work with.
The two-stripe photo to match the monkey meme, with electrons and measuring which-way information, probably doesn’t exist yet. So that’s why!
I want to clarify that the “cannot” here refers not to the inadequacy of our tools (which hypothetically could have been fixed in the future by building better tools), but by a fundamental prohibition of the quantum mechanics theory. Practically, the single-photon lasers and detectors used here are like 90%+ efficient - plenty good enough to distinguish between the two monkey scenarios. But some observables in quantum mechanics are “orthogonal” - you can measure one or the other, but not both at the same time - the math will not allow it. The typical example of that is “position” and “momentum” of a particle.
The math is quite beautiful actually, the analogy I’d use is something like asking “Which way is east at the North Pole?” In your head you can either know “This direction is east.” or “I am standing at the North Pole.” but you cannot hold both pieces of knowledge in your head at the same time.
The orthogonal observables in this experiment are the “which-way top/bottom slit” information and the “which-interference-category Pattern 4/Pattern 5” information. It’s even more beautiful in the delayed choice quantum eraser experiment that I was ranting about here. There, both pieces of information are stored orthogonally in a single photon. You can choose at a later time to either measure it one way, which will tell you the which-way info, or in a different way, which will tell you the interference category info, but there is no hypothetical way to measure it in both. The only way you can get the category info out to allow your computer to draw the interference pattern is if you guarantee that the which-way information has been irrecoverably erased. It is as if the whole universe conspires to censor this information from you! But it’s just the consequence of the math rules in use.
