here we go, in no particular order:
claer=clear
gvim='nvim +Gclog +Git'
vim=nvim
vi=/usr/bin/vim
v=/usr/bin/vi
glog='git log --oneline --graph --all'
rcp='rsync -r --info=progress2 --partial'
d0='du -h --max-depth 0'
d1='du -h --max-depth 1'
ls='ls --time-style=long-iso --color=tty'
icat=chafa
ssh='TERM=xterm-256color ssh' # (kitty messes with TERM)
Harry Potter characters is a perfectly reasonable server naming scheme. Server names should be easily recognisable but not tied to any particular service/project/function on that machine (as the server may be used for other things later etc)
See RFC 1178: https://www.rfc-editor.org/rfc/rfc1178
Speaking from experience, I'd recommend not choosing protonmail because it is very difficult to cleanly stop paying and leave - forwarding mail to another address is a paid feature. It's also not very standards compliant (no IMAP/SMTP support without running a buggy bridge). Their security features are mostly useless and better security can be achieved on standards-compliant services if you try.
I can't spell when typing fast :P
