I threw my Canon multifunction in the dumpster the day it didn't want to scan because it was out of yellow ink... I've been in the Brotherhood ever since.
New icon is really ugly... Default launcher on Samsung phone.
Otherwise a really great app!
I know it's not Linux, but if you're looking for a Unix system, I've had good experience running SD on a M2 Max MacBook pro. It does ~1-2 iterations per second at 512 pixels.
My favourite one solved a long-standing argument between my wife and I. I like to keep my office slightly warmer than the rest of the house, and she hates wasting electricity by heating it when I'm not there. She would keep lowering the thermostat when I was not working (like on the weekends), and I'd come back on Monday and wonder why I'm freezing in front of my computer.
I solved it with Home Assistant and a smart thermostat. Now whenever my computer becomes active, it sets the thermostat to my favourite temp, and when it's asleep (or away) for more than 15 minutes, it sets it back to the "away" temp. Lights are also synchronized with the whole thing.
