Probably nothing helpful as you are already way past my understanding. Maybe look at the Darktable documentation or even the “green lantern” stuff (IIRC the name). GL or (something) Lantern is/was an open source software for Canon cameras that breaks out all DSLR features on nearly any Canon camera. Nearly a decade ago, I had a makeshift product photography studio and messed with Macbeth color charts and profiles matched to a monitor. The tutorial guides I followed were from these two projects IIRC. GL.

The main problem is when following instructions for command line tools. They might figure out how to use dnf instead of apt, but the extra layers required for ostree are not very friendly. There are a ton of potential frustrations in this area, especially with GPU stuff or hobbyist hardware like Arduino where kernel stuff is needed in userland. At least as of nearly 3 years ago, the documentation in this area sucks. I was on Silverblue for a few years and managed to get through the frustrations due to intermediate experience level. I found toolbox useless compared to distrobox. But using this with something like Arduino was annoying at best. The needed dependencies expected by whatever stuff I wanted to install was usually a big mystery with near useless error failure messages and names of packages and libraries totally unrelated to the package naming in DNF. When updating the base OS, stuff built in these containers is totally useless because I could not update the containers to the new OS image. Playing around with Flash Forth on a microcontroller was even worse. I ended up layering a bunch of stuff on the host because the containers were just not working. When I got an Nvidia machine, I went to Fedora Workstation and have had far fewer issues and frustrations. SB wasn’t bad, but it is a pain to use these if you need kernel level access. Just my $0.02. I was actually on SB for ~2-3 years.

Depends on the system. Typically, the older systems do not work like this. The GPS satellites only transmit a signal that contains their location information and the time. The device must collect several of these signals and then use trigonometry to calculate your real location in time and position. Yes there are relativistic effects due to the distance to the satellites and gravity. For instance, in home lab electrical engineering, if a person wants a really good reference clock but cannot afford a cesium atomic reference, they can use a relatively cheap GPS system to build a referenced oscillator that is disciplined by the reference clock on these satellites. I think they are cesium too, but it has been awhile since Dave Jones made YT uploads on the eevblog about it. A Garmin bicycle computer is another example. It is triangulating the signals and plotting periodic waypoints with some basic averaging. That said, WiFi routers and cellular towers are possible to use for similar triangulation. Maybe check out Hak5 if they are still around. It has been awhile since I looked them up, but they used to make pen testing red team stuff that will infer much about vulnerabilities.
