  • Out in NYC, the bodegas all have a little plaquard saying that either 1: listed prices include a 2% credit card fee and you can save by using cash, or 2: listed prices may not match your final charge because they add a 2% fee on top for credit cards.

    Which is the same thing effectively but it can be sometimes confusing if you’re trying to watch for the fee.

    Anecdotally, I have sometimes noticed the cashier will say a price, and then say a slightly different price when I pull out the card. So it’s not like they always apply the fee regardless. At least some of the time anyway.

    Not universal of course. I don’t remember if that’s also true for grocery stores, and it’s probably not the case for big chains but honestly I don’t know.


  • Aphantasia is neat. I have to wonder how it affects the way we see the world. I’m 1. It doesn’t really take concentration, which I see on here? it’s not any harder than just a simple internal monologue anyways. But that’s always in motion whether I want it or not so 🤷

    That’s including lights and reflections, but like that’s constructed by me, and so I might imagine a light reflection incorrectly. again just like I might have a definition incorrect for internal monologue.

    Anyways, sure. Imagining is part of it. Like placing yourself in the situation in front of you. I don’t need adult videos to do so though. But like, having full HD imagination doesn’t replace videos of any kind, or else I wouldn’t watch YouTube either ya knoe







  • Yup, it’s why O(N+10) and even O(2N) are effectively the same as O(N) on your CS homework. Speaking too generally, once you’re dithering over the efficiency of an algorithm processing a 100-item dataset you’ve probably gone too far in weeds. And optimizations can often lead to messy code for not a lot of return.

    That’s mostly angled at new grads (or maybe just at me when I first started). You’ve probably got bigger problems to solve than shaving a few ms from the total runtime of your process.


  • The problem breaks down into a few broad sub problems, as I see it.

    1. Confirming the reviewer or voter is who they say they are (to prevent one entity from making multiple reviews).
    2. Confirming the reviewer or voter is a valid stakeholder. This is domain-specific, but can be such metrics as “citizen of country”, or “verified purchaser”.
    3. Confirming the intent of the reviewer. This meaning people who were paid off (buyers who are offered a gift card for a positive review, which happens plenty on Amazon), or discounting review bombs when a game “goes woke”.

    1 and 2 have solutions. Steam cares about whether you’re a verified purchaser, and the barrier to entry of “1 purchase of a game per vote” is certainly enough to make things harder to bot. Amazon might be able to do the same, but so much of the transaction happens outside their purview that a foolproof system would be hard. Not that it’s in their interest to do so, though.

    For places like Reddit or Lemmy, verifying one human per up vote is going to be impossible. New accounts are cheap and easy as a core function of the product. bot detection is only going to get harder, too.

    If you used some centralized certificate system (like SSL certs), you could maybe get as granular as one vote per machine, but not without massive privacy invasions. The government does this for voting kinda, but we make a point to keep those private identifiers the government gives private.
