how to ideally set up a new uberspace instance

create uberspace
create SSH key (with password, key longer than RSA 8192)
integrate SSH key into kitty (or your preferred program)
login SSH
uberspace tools version list php
uberspace tools version use php (whatever is newest)
do the same thing with any other software you have to use (like MongoDB and so on) now: set the newest version BEFORE you begin projects.

uberspace web header set / Permissions-Policy "browsing-topics=()"

(that's about Google Topics, formerly FLoC)
