    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


  • 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.















  • 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.
