I'm using mxlinux "ahs" version, it comes with kde at their "ahs" repos for supporting latest hardware and graphics cards. You may also check for the non-ahs, there might be a meta-package for kde plasma and that's it..
we should definitively have a wiki (though people should use "search" too, I wonder if a wiki would help really). This "topic" comes every month. I have posted this already, here it goes again: https://github.com/anderspitman/awesome-tunneling
Perhaps a chronological view is a bonus of the idea lives on for long enough. And having links between stories, or tags can be useful at some point too... https://www.usememos.com/
You can check on arduino and ESP32 Boards for IoT. That was a hobby of mine, it never took off (albeit, a hobby so it's fine). But I learned a lot about "low level programming" that had no idea it even existed, and there was some interest overlap with self-hosting (home assistant wasn't around at the time, played with Mozilla's mqtt). The latter did took off (I still enjoy doing it).
FOSS thrives in options, and that's just great. There's a compromise between security (i.e. anonymity) and convenience (i.e. speed). This tool focus on the security side. Meanwhile, seedboxes strike a good balance to both. That's the current scenario, there are many ways to share. That diversity provides resilience to the communities ;)
Idk. Yet, I have recently found out that some are able to measure Capacitance. I think those are useful, since many times a repair work is about replacing a fat capacitor. But I am quite a neophyte on regards to electronics... Take this with a grain of salt.
