Marshall has copyright on his lyrics, you just said yourself patents and copyright are different things.

Sufficiently different rip-offs that don’t confuse consumers as being the original should be legal. They already are as far as copyright is concerned.

Many design patents should never have been registered, and should lose when defended in court. Design trademarks are a third similar issue.

It’s going to have some metadata to that effect yes, like a file index or number of parts or total extracted file size. I don’t know the details, I’ve used them I haven’t read the spec. rar is Rarlab’s proprietary format so there might not even be a public spec.
They’re normally all the same size except for the last part, so it’s not that file 1 is just an index.

Yes, it asks for the next part if it’s not in the same folder with the same name, doesn’t really make a difference what it’s stored on. Multipart zip and tar also exist.

Multipart archives still exist. They’re now used for file sharing websites that have a maximum file size. Before that they were for unreliable p2p networks, so you didn’t lose the parts you’d already downloaded when your peer goes offline. Originally it was to fit something big on multiple cd-roms or floppies.

Opening somthing.rar also reads the data in somthing.r01 through somthing.r15 etc

It’s good for email and personal sites (those aren’t dead, but they’re more popular for people that either write a lot or are self-employed). I’d only use a personal domain for self hosted apps if the users are just you and your family.

For something like hosting Lemmy, with users you don’t know, I wouldn’t use the same domain as where you host your other personal stuff, even if it’s not your name.

There are multiple of us! I did the exact same thing, except for using my own name. Mine ends in .re of Réunion. I think it’s fun so I’m keeping it.

For sharing it offline I have a big text widget on my phone. They usually get it if they can read it, but not if I spell it out.
