It’s unlikely to cause anything to outright fail, but it will certainly be creating bottlenecks and inefficiencies

That’s going to be a problem whatever solution you come up with, because of the federated nature of the lemmy system.

There’s no central authority to hand out usernames, so if two people sign up to different instances with the same username, any design which didn’t attach instance name to each username would fail. The only way around it would be for each instance to contact every other instance which exists, including the ones which haven’t federated yet, and negotiate ownership of the new username, and that’s just not possible

The crew of Apollo 13 weren’t really stranded, as such. They were far from home and not sure if they had the means to get home before the supplies ran out, which is a different problem

While that sort of analysis probably isn’t impossible, it is computationally unrealistic to do in realtime on a language which wasn’t designed for it.

It’s the sort of thing which is simple in 99% of cases, but the last 1% might well be impossible. Sadly it’s the last 1% you need to worry about, because anyone trying to defeat your system is going to find them

There’s no need to leave earth, just lift it into a medium earth orbit. There are literally thousands of kilometres in between low earth orbit (where there are lots of communications, spy, navigation and weather satellites) and geosynchronous (where there are lots of communications satellites), and outside of those two there’s virtually nothing there

In principle they could have pulled out slightly, if there’s jostling and tiny movements in skull then you’d expect them to work loose over time if they’re not securely anchored

Well it’s definitely alive, that’s not a terribly high bar (plants and sponges qualify, after all).

The ethics question is whether it’s a person yet (or should be treated like one)

The Artemis 1 launch was also staggeringly expensive, and yet to be repeated.

In the time it’s taken to develop that rocket, SpaceX has gone from it’s very first real flight (by which I mean actually achieving something, rather than a pure test flight) to launching far more every year than the entire rest of the world combined. Note that by that definition, Artemis hasn’t had a single “real” flight yet.

It depends on what exactly gets cut or punctured, of course, but my understanding is that without proper surgical intervention it can be an exceptionally slow and painful way to die.

The organs in the gut are mostly intestines. You’re not going to die just because they’ve spilled out, but you’re going to be bleeding pretty badly and if whatever caused them to spill out is still around then you’re pretty screwed.

The bigger problem is that it’s unlikely they’ve just spilled out, they’re probably also sliced open. Now you’re in serious trouble, because there’s lots of blood in there so now you’re bleeding really badly. You’ve also got blood and the content of your digestives system mixing together, and that means some very nasty bacteria which are normally safely contained now have access to your blood.

I suspect the most likely dangerous situation is a stab wound. In that case you’ll probably experience internal bleeding. There are no shortage of places for blood to go inside your body around there, including into your digestive system. I don’t think there’s anything much to stop blood from flowing endlessly into there, and you could bleed to death even if the external wound doesn’t look like it’s bleeding all that badly.

In summary, getting stabbed in the gut will contaminate your blood and lead to potentially endless bleeding which can’t be treated with bandages because it’s inside. Even if you avoid bleeding to death, you’re probably going to die from a massive infection

Perhaps not, but it would make it far easier for any sympathetic brain surgeon you managed to find who was willing to try and fix the problem for you.

The key thing is not needing that specific company to help, but needing generic expert assistance is fine

I find it makes my life easier, personally, because I can set up and tear down environments I’m playing with easily.

As for your user & permissions concern, are you aware that docker these days can be configured to map “root” in the container to a different user? Personally I prefer to use podman though, which doesn’t have that problem to begin with

Podman supports docker compose just fine. You have to run it as a service, so that it can expose a socket like docker does, but it supports doing exactly that

Because a container is only as isolated from the host as you want it to be.

Suppose you run a container and mount the entire filesystem into it. If that container is running as root, it can then read and write anything it likes (including password databases and /etc/sudo)

The only thing I’d add is “not particularity nice to the Muslims living there” is putting it mildly.

Because there’s always tension, Israel takes its security very seriously. Unlike most countries, who put a token effort into security most of the time, Israel really is an armed fortress. That makes it very easy for someone with an itchy trigger finger to shoot someone who didnt deserve shooting. Even with the best will in the world, it would happen from time to time.

That, of course, makes the Palestinians very angry. An angry population poses more of a threat, and is more likely to do something genuinely aggressive. The Israeli security is thus tightened further, and their soldiers get even itchier trigger fingers and around and around we go.

It doesn’t take long before everyone involved has a personal grudge for one reason or another, and things can get really vicious.

Personally, I’m alarmed that a bear only merits closing half. Did the guests in the other half do something to make themselves unpopular?
