Hosting your own services. Preferably at home and on low-power or shared hardware.

it takes time to be good at it, but maybe you could start with Yunohost and slowly learn the ropes.
a book - https://ziurkes.group.lt/book/4399/s/unix-and-linux-system-administration-handbook (use it as a reference, not as a novel - it is more than 1k pages)
Well 1k pages does sound a little off putting (not because inherently bad, just because my real life only permits so much time for tech shenanigans). Yunohost I have looked into and that might be an option I could get along with. It seems to be a bit like the Softaculous installer that comes with my shared hosting, I think.
Edit: didn't even say thank you for the book link - btw is that a bookwyrm instance?
yep, bookwyrm ;)
Soo, do you happen to have a list of bookwyrm instances one could check out? Asking for a bookwyrm
Honestly, if it's just for you and family or friends, just take the Yunohost route! Super easy to do everything :)
