Yes, but the phones of all your peers will have that shit on them.

What are you talking about? I exchanged multiple mails per day when I had a problem.

Also as others have mentioned, the parts are still available on their website.

Please don’t call yourself stupid. The common internet slang for that is ELI5 or “explain [it] like I’m 5 [years old]”.

I’ll also try to explain it:

Docker is a way to run a program on your machine, but in a way that the developer of the program can control.
It’s called containerization and the developer can make a package (or container) with an operating system and all the software they need and ship that directly to you.

You then need the software docker (or podman, etc.) to run this container.

Another advantage of containerization is that all changes stay inside the container except for directories you explicitly want to add to the container (called volumes).
This way the software can’t destroy your system and you can’t accidentally destroy the software inside the container.

Yeah, flatpaks that just write into $HOME/.var are a prime example of how not to do it.

You code in Java, of course you should self flagellate on a daily basis just for that. The entire ecosystem is completely fucked.
