Fair enough, I should have said that there's no other built-in way to set the time on them.
I work with 3d printers in a school that uses its own NTP server and blocks other requests. The only way I managed to set the time on the machines sort of using a raspberry pi or something, was to connect them to my phone's hotspot.
The Prusa printers have a hard coded IP address for NTP requests. There's no other way to set the time on them. At least it's to a well known public organization in the Czech Republic, but still.
I'm fairly certain you could still run that shell script on steamOS? I don't understand why an immutable distro would keep you from doing that. It's essentially what Lutris and Heroic Games launcher do.
Are you talking about an ultrasonic humidifier? AFAIK, those shoot out tiny water particles along with any bacteria that might be present, creating a health risk. You're meant to only use distilled water with those.
Can you elaborate? Is there any controversy on the Core One I'm not aware about, apart from it being less open source?
