As an idea, I use an SSD as a “Default Download Directory” within qBittorrent itself, and then qB automatically moves it to a HDD when the download is fully finished. I do this because I want the write to be sequential going into my ZFS pool, since ZFS has no defragmentation capabilities.
Hardlinks are only important if you want to continue seeding the media in its original form and also have a cleaned-up/renamed copy in your Jellyfin library. If you’re going to continue to seed from the HDD, it doesn’t matter that the initial download is done on the SSD. The *arr stack will make the hardlink only after the download is finished.
Screen-sharing is part of chat apps nowadays. You’re fully within your rights to stay on IRC and pretend that featureful chat is not the norm these days, but that doesn’t mean society is going to move to IRC with you. Like it or not, encrypted chat apps have to become even more usable for the average person for adoption to go up. This reminds me of how all the old Linux-heads insisted that gaming was for children and that Linux didn’t need gaming. Suddenly now that Linux has gaming, adoption is going way up - what a coincidence.
Edit: Also for the record, I have a tech-savvy friend who refuses to move to Signal until there are custom emoji reactions, of all things. You can definitely direct your ire towards these people, but the reality is some people have a certain comfort target, and convincing them to settle for less is often harder than improving the app itself.
