Doesn’t take long to get over that redd slut. I’ve been here on .world since 1.21k total users on the 9th. I haven’t touched old redd ever since. Every time I see results show up in a search, it’s like an annoying text message after leaving that cheating whore. Ive got more self-respect than any fool that responds to such nonsense. Once a cheating whore; always a cheating whore, as far as I am concerned. Welcome to the next chapter of the internet.
Other people have said the same, but Apollo was my most used App on my phone.
I find that during the day, I mainly browse Reddit on my phone, as I can’t stand not having RES on my work laptop. I’ll have to see what sort of adjustments I’ll have to make, as I was looking at using both Reddit (via browser on my laptop) and Lemmy (via wefwef on my phone) whilst the lemmy community gains a bit more traction.
This is all kinda blind speculation and there will be a formal report eventually, but as a general outline:
-When carbon fiber fails, it tends to fail spectacularly: completely and suddenly. So you can think of it not as "crushing a tin can" but more "smashing a glass lightbulb, but from all sides at once".
-If we randomly assume they were halfway down (no idea on where they actually were but as a blind guess 50% is a good starting point) that's about 200 atm of pressure. 1atm = ~15 psi, so thats about 3,000 psi. For comparison, a typical firehose is roughly 100 psi. And that can do serious damage to people: if a badly threaded cover pops off a charged hydrant, there is enough force behind that to break bones. If you were sitting next to the hydrant it'd hit you faster than you could react - you'd only know it after you'd been hit. The water outside the sub is at 30x that pressure.
-Lets assume just as an arbitrary approximation that in the first instant of the carbon fiber failing catastrophically, an area roughly equivalent to a 3ft diameter circle fails (it probably actually fails by buckling in a line then milliseconds later splitting and shattering, but we're just approximating). This means that the water that flows through is pushed by 30x as much pressure as a firehose, and that pressure is coming in across 200 times as much area as a firehose (which are typically 2.5in diameter), so there are basically 200 of those 30x-power-firehoses coming through at once.
-A 2.5in firehose will do ~300 gpm. 6000 firehoses would be 1.8 million gpm. The internal volume of a 2m diameter/4m long cylinder is about 2,500 gal. That would be completely full of water in 0.001 seconds. Of course in reality water doesn't hit full speed instantly, fluid flow is far more complex than just multiplying through like this, etc. But this just drives home that we're talking very very small fractions of a second.
-Yes, compression = heating and when its super fast there isn't much time for heat transfer so its adiabatic: wikipedia has an example under "adiabatic compression" for 10:1 compression going to about 500dec C (in an engine) and this is more like 200:1. But remember that air has low specific heat capacity and also doesn't weigh much. The specific heat capacity of water (i.e. humans, plus those 6,000 firehoses worth of water) is ~4x that of air, and the density is ~1000x as much. So if you have equal volumes of air and person, and you heat the air by 4,000 deg C, that contains roughly enough energy to heat the person by 1 deg C. And also refer back to "there isn't much time for heat transfer". So chances that this actually matters beyond detailed physics calculations are slim.
Bottom line: completely obliterated by the force of so much water under so much pressure. By the time any water entered the sub it should have been over faster than a human could perceive. No explosions or incineration though, just force.
Also, common misconception: pressure alone doesn't hurt you. You would not be directly hurt by spending time anywhere from the complete vacuum of space (0atm) to the challenger deep (1,000 atm). Obviously there are other little complications like you can't breath in 0atm and that'll kill you quickly, but the pressure itself won't. Conversely at high pressures oxygen becomes toxic which isn't great for staying alive, but the pressure itself isn't the issue. Very rapid and therefore very violent pressure CHANGE, however, can and will kill you in many horrible ways.

The wreck was found 500m away from the wreck of the Titanic, the Titan descends in a curve and not straight downwards, gives pretty good indication that they were near the depth of the ocean floor. Combine that with the fact that they descended faster than anticipated and that they lost communication right around the time they were supposed to reach the lowet point, I think they were close to the ocean floor.
The reason is federation. People actually happen to be pretty good at holding each other accountable and self-regulating when there isn't a central authority deciding what is and isn't acceptable. Bad actors naturally gravitate toward the instances that welcome them, and then the rest of us defederate from those instances to maintain the peace. Those bad instances then stagnate or fizzle out from the inactivity.
On centralized social media, what stays and goes isn't dictated by the community but a handful of people at the top, and troublemakers are often given a bigger platform than they would have had otherwise.
Mastadon is a lot bigger and older than Lemmy is, and yet it still has the same vibe as this place.
So instances choose which instances to federate with? Does this mean that if my account is on lemmy.world that I’m seeing a selection of what that instance’s owners choose?
Other way around most of the time. Instances choose who to defederate with. If you view all posts instead of local You’ll see posts across the fediverse so long as the instance owner hasn’t defederated. Defederation is also a pretty nuclear option so it’s generally not taken lightly.
I think the play is to force everyone onto the official app so we’re totally locked in. Then, they can enshittify it for maximum lucrativeness, and we won’t be able to switch away from it.
Most third-party apps don’t show ads which lessens the potential revenue for the first-party. Their idea is that by stopping these options, people will use the “official” methods which will allow serving of ads.
