Is there any list of "tech for a hostile world" anywhere? 
Not specific lists like "made in EU" or "privacy-friendly" or "decentralized" or whatever, but an aggregrate list of tech that's likely to be of use in an environment or world where you need to ensure your safety in some way, and build community with others to survive.
(If the listing criteria are entirely technically-oriented and don't take into account social factors, it's not what I'm looking for. Please check for this *before* recommending something.)
For an example: Reticulum would be something that might be on the list. So might alternative firmware to revive old abandoned devices. Or tools for organizing things in a communal living setting.
