    5 meters is definitely way too short for the chair swing ride. Look at the people in the seats. It’s definitely at least 10 meters.

    Assuming 10 meters and 100 km/h, that gives about 7.9 g. That’s in the range of what fighter pilots might experience and well beyond where most people black out, so that’s still definitely too high.

    Looking it up online, this is a pretty classic physics problem and the numbers you might see around it are closer to a radius of 12 meters and a speed of 13 to 17 m/s. Taking that as 15 m/s (54 km/h), that works out to about 1.9 g, which I can subjectively say feels much closer to the real value if you ever ride on one of these.

    So, the second one is about 1.9 g






  • I recently had a complaint with a website:

    “Users are having trouble scrolling!”

    My response:

    “Are they using the scroll wheel/directly scrolling with the touchpad, or using the scroll bar?”

    They were, of course, using the scroll bar. I am now somehow responsible for design choices made at the level of the browser, because browsers have decided that the scroll bar should be nigh impossible to use. Yippee.

    Evolution doesn’t really care about quality of life, so long as an organism still reproduces. If every organism in a species is in horrendous, absolutely unconscionable pain and suffering for their entire existence but always manages to successfully pass on their genes, then the species can absolutely be deemed “successful”. In a way, we have a symbiotic relationship with e.g. cows: even if we cause them mass suffering as individuals, as a species our relationship is mutually beneficial and that’s all evolution really cares about at the end of the day.

    There are billions of cows, chickens, etc. in the world. Purely by numbers, those species are incredibly successful. Yet, If not for humans finding them tasty and easy to manage, we would not have bred them to this degree and they wouldn’t have reached this degree of success. Somehow, against all odds, being tasty/something we want to eat has somehow become an incredibly valuable and successful adaptation.

    Evolution is absolutely wild, and this really drives home the fact that evolution isn’t about the individual’s likelihood of survival, but their likelihood of reproduction.




  • and your phone only has one number… right?

    Dual-SIM phones are a thing and have been for a LONG time. They’re not as common in the US (where I’m assuming you’re from given you aren’t familiar with dual-SIM phones) but even my S22 supports it, and I think even iPhones come with it stock now. A lot of people use two SIM cards for a multitude of reasons, and so many people have two numbers. Heck, some phones even support three SIM cards.

    Dig they bring out a PC client yet btw?

    It’s been out for a long time now. You have to set it up on your phone first but then you install the application on your computer, scan a QR code to link it, and at that point you can just disable notifications on your phone if you don’t want them.



  • I do too. To be clear, I did NOT mean that we could go without it today. What I meant was that if we didn’t have it to start with, things would’ve likely still developed albeit much more slowly.

    I’ll also preface this by saying I definitely slightly misread everything before and so my reply was kinda crappy







  • DDOS is a pretty brute-force attack, so it isn’t typically relying on a vulnerability per se. Pretty much the only way to mitigate it is to have large enough infrastructure that you can detect and filter out its gobs of spammy traffic, which no Lemmy instances (at least at the moment) can really practically have. They could potentially use a service like CloudFlare, which does have that infrastructure in place, but that can be expensive. I’d imagine CloudFlare (or a competitor) is probably the best solution they can go with, at least in the short-term.
