I find it deeply disturbing that there isn't some simple sanity check that prevents the device from delivering a fatal dose.

- shabble 15y agoI don't know about diabetes and insulin specifically, but what constitutes a fatal dose might not be easily calculable up-front. Obviously, there'll be a dose that will be deadly in all cases - the LD100. But the statistical "half the people given this dose" LD50 measure could easily vary by ± 100% or more. Things like metabolic rate, body-weight, route of administration, insulin tolerance, and relative blood-sugar levels could all factor into the dosing system, and I'm guessing the whole point of having it remotely configurable is to minimise the processing effort on the embedded chunk.
- carbocation 15y agoI see that your self-asserted lack of domain-specific knowledge did not prevent you from giving the correct answer. Good.
