Fun fact: bit-flips in microcontrollers usually don't originate with cosmic radiation, but with chip packaging which is (or can be) very slightly radioactive.

A pretty bad edge case with an old intel cpu was mentioned in the linked video as well.

An interesting case of bitflips also came up a couple of months back having to do with google’s certificate transparency log. https://news.ycombinator.com/item?id=27728287
