Some devices or software will ignore what the os or network are telling them and use their own DNS servers, mainly to bypass filtering. If that's what's happening then you're mostly out of luck. The best you could do is set up firewall rules to block those other servers, assuming they all even use port 53, but that would probably just prevent those devices from working at all.
It's not completely out of the question that you could intercept and redirect those requests, if they're not encrypted
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
The latter, I suspect. That's certainly how forming a neutron star works in the first place, because if a star gets so dense that it can form neutronium then the neutronium (which is far more dense than the core was before) can easily keep making more.
It's a similar story with black holes. Get past the threshold at which it forms, and the process runs away and swallows the whole star.
If a quark soup is more dense than neutronium, then it would be fairly all-or-nothing
The satellite uplinks these devices use is very bandwidth limited, and quite expensive. I can assure you that it's not routinely sending anything without telling you.

I'm pretty sure comments get sent back to your instance, so comments from instance B will work just fine.
I have no idea whether instance B will propogate things which have been federated to it though.
It's also not obvious that an instance you're not federated with can't do their half of the federating, if they're so inclined, and show content from instances which choose to defederate. At the end of the day you'd have to trust all involved to put in some effort to respect the decision to defederate
People keep talking about this work as if it offers some meaningful insight into how these systems behave, when the whole premise requires a fundamental misunderstanding of what GPT is actually doing.
The idea that you could present it with information but ask it not to use that information is absurd. At the end of the day it's a sophisticated word association engine. It doesn't have intent, it isn't capable of strategy.
This is like pointing out that a dog which has learned to shake hands is actually deceiving you, and it doesn't really mean any of the social things we use handshakes for (except it's worse, because the dog is actually capable of being sociable)
Fluid handling in free-fall is a nontrivial task. While it's true that linking tanks in two different vessels is also a technical challenge, there's plenty of value in demonstrating that you can pump the fluids around at all
It was different for the upper stage. That was a fast rotation messing things up, but in this case the hot staging seems to have pushed harder on the booster than they expected and lifted the fuel away from the bottom of the tank.
They've solved one sloshing issue, but the solution for this one will be different
They seem to have calculated km/h/s, and labelled it km/s/s
First stage worked beautifully, but engines started failing after stage separation and it self-destructed.
Second stage also looked like it was going perfectly, but a few seconds before its burn ended it also self-destructed for no immediately apparent reason. It was literally seconds away from achieving orbit
The rocket is very careful to keep the oxygen and methane separate. To make the tanks explode they'd need to spend a lot of time mixing them, which isn't good enough for a self-destruct. It would also behave differently in different parts of the flight. The equipment to do it would be big and heavy as well.
Instead, they use explosive charges because they're lightweight, reliable, and quick to detonate (last launch notwithstanding, because of a design problem)
The story I heard was that charging is taking far longer than usual because of cold batteries, and people are having to change much more frequently for the same reason, and between the two the demand for chargers has shot up
