Pairdrop is probably a miracle tool for me. Just open the website and send files or text, no configuration, no fuss and it even works outside of the local network.
One day I'll finally set up my own server, but that's just for the fun of it. One hosted at https://pairdrop.net is super solid and I can't remember it failing me.
Oh... I can't imagine waking into that.
Beautiful picture by the way
