This made me think. Is a cosmic ray human error because we were unable to prevent it damaging the system?
- kaba0 4y agoHow many cosmic ray bitflips happen? Even without ECC ram I’m fairly sure I have never seen any affect me, so there is that (even data hoarders with terabytes of data stored with e.g. ZFS seldom report problems due to that - when they start to see checksum errors it likely means a soon to fail harddrive instead) Also, if I’m not mistaken, in airplanes which are much more likely to get hit by cosmic rays at high altitude, they often use redundant CPUs that work in lockstep with each other. So.. in the end it is human error I guess? Handling unexpected cases should be done well as well.
