Here's an alternative to AirDrop! https://github.com/spieglt/FlyingCarpet Linux, Mac, and Windows, requires no network, just two laptops with wireless cards.
Thanks! I will be using this a lot.
I use Syncthing for this kind of transfer involving non-Macs although that's because I'm always transferring between a set of known hosts, not ad-hocly. Works well enough.
syncthing is great, but i find it a bit difficult to use for one-off or one-way transfers
Snapdrop[1] works quite well if you're on the same network. It's cross platform, you only need a reasonably recent web browser.
I pine for the days of drop.io to return before it was acquired and dropped (BA-dum PSH!). That was, hands down, the best and easiest way to get files from one place to another.
