@lupyuen Hi! quick technical question, how portable is the work you've done on the #PineCone to other #BL602 based boards? looking at this one: https://www.analoglamb.com/product/bl602-risc-v-wifi-bt-board-dt-bl10/

@lupyuen Well one of your stash looks like a DHT11, and that's even on the first page of https://crates.io/keywords/embedded-hal-driver

@lupyuen Yes: Use #Rust drivers based on embedded-hal, then you don't need to find those matching your OS or port anything.

@lupyuen brb, buying more Raspberry Pi's. :P

@lupyuen Almost certainly yes. Remember from an epidemiology point of view, lots of people were saying the privacy-preserving versions wouldn't work very well anyway. So no surprise there was pressure on multiple angles to have privacy in name only.

Fact is the contact tracing efforts have found that it mainly spreads at hospitals, at essential jobs, and within families. The short encounters that tracing apps monitor best don't matter anyway. You need relatively long exposure to get infected.

@lupyuen I think cryptographers were far too willing to promote tracing in general by coming up with "private" schemes for it. Those schemes helped legitimize the idea in general, including the versions with no privacy at all.
