Too socially prevalent. Most people know about this change, but they still use the old one. Anything official are now using the standard age, though.
Anyone born on Jan 1st stays one year old for the whole year since people gain age every time the year changes. This does mean that a person can be born on Dec 31st, and be two year old next day.
I don't think Lemmy ever claimed they're decentralised, because it has a specific meaning that sets itself apart from being federated, and Lemmy certainly isn't decentralised.
The whole freedom of federation comes from the fact that if you don't like something, you're free to set up your own stuff and do it there. In practice, it doesn't work that well as advertised especially for something like Lemmy, which creates an additional layer of isolation (communities) within itself, but it requires a large group of people in a single community to work. I think Lemmy needs a way to '"merge" communities across instance.
() creates a subshell, and & runs the command in background. The $@ means everything after the first argument, so the <command> is executed like a normal command. I am not sure why this works, but it has worked more consistently than nohup, disown, and it's a lot shorter than most other solutions.
IIRC disown is a shell built-in command, so its use is a bit limited. Not sure if & is also a built-in, but I found disown to not work in some situations. Besides, it's shorter.
I have a script named d in my PATH and it contains this:
("$@" > /dev/null 2>&1 &)
It allows me to run any program in a fully detached state in a way that works even if the terminal that started the program closes, and it's as simple as d <command>.
