Nice idea about the GPS receiver, I hadn't thought of this workaround.
I ~recently got a Fairphone as well, and while it's the next model, the fact that I can see them still supporting the FP3 with both hardware and software was what convinced me that they'll probably keep the same promise with my model in the future.
Apart from no headphone jack and it being a little bigger than I'd like, I'm very happy with the FP4. I intend to use it until the end of its 5-year warranty, and reading about the longevity of yours makes me optimistic. Thanks for sharing!
It would be nice if popular science articles' headlines showed more nuance. "Reveal" is too strong, "suggests" would describe it better.
Interesting study regardless of what findings it represents, though. Analyzing centuries-old grain traces on blades sounds like something out of sci-fi; I wonder what tools archaeology will have at its disposal a few decades from now.
