Immich looks particularly good to me.
It is! Been running it for a few years now and I love it.
The local ML and face detection are awesome, and not too resource intensive — i think it took less than a day to go through maybe 20k+ photos and 1k+ videos, and that was on an N100 NUC (16GB).
Works seamlessly across my iPhone, my android, and desktop.
50kW class laser.
Another source claims 1um wavelength with individual 1.5kW lasers in a hex pattern — unclear if it’s a phased array (would be awesome) or just trained on the same target (source mentions they are “combined using a mirror” so probably the latter).
Sounds like maybe high power YAG?
