podman works on windows hosts, as long as you don’t need windows containers

you have to be more specific lol

just tesselate the world with hexagons and say you’re in a specific one? that doesn’t give precise proximity but does expose your general area.

this does the opposite, doesn’t expose your general area but let’s you determine if it is close to some other location via an expensive comparison. the precision of proximity isn’t tied to how precise a location/small a hexagon you’re exposing

sorry no, the servarr site. look at this section for docker info. I think the links from there should have most of the background info

the docker builds it uses are unofficial technically, but the source is here, you can see that the only thing it does is download the official build

the first dockerfile linked on the official site is pretty simple. read it to make sure it’s safe, then build it locally yourself.

as per the first paragraph of the intro of the linked paper, it’s safer to store this than it is an actual location. if data gets leaked it’s like leaking a hashed password instead of a plaintext one. their example is device trackers.
