Today I discovered the #MagicWormhole protocol. There are desktop and mobile apps and it essentially allows the transfer of a file between any two computers, as long as they are both online. You select a file, it generates both a QR code and a seed phrase of sorts that you can then give to a recipient to plug into their application, and transfer a file. I have my own home server, but for one off transfers of files that are too big for email or a messenger, this would be easier.

Private, encrypted, open-source file transfer. It used to be "Firefox Send", but Mozilla discovered people sent things Mozilla wanted no part of. So since it was open source, other people started running servers. I find it's super useful for transferring log files around the world.
