@nprofile1q... Is this (unified attestation) an analog of whatever it is that google does in apps that ends up with things like banking apps needing google services? Or am I thinking of something completely different?
@nprofile1q... I have a copy of this. I can wholeheartedly recommend it as grade A adventure, generally excellent, and just an absolute delight to read.
The other aspect of alternative communications that I've been very curious about for a while is the LoRa mesh networks. Very low bandwidth, but enough for text.
@nprofile1q... there are apps that can do that, but it relies on everyone having the same app. Years ago, at burningman in the states a bunch of used one. I think it was firechat - defunct now by the look of it. Created a local mesh using wi-fi. Didn't work perfectly, but often worked enough.
