What Flips Your Bit: Cosmic Ray Errors at Mozilla
I don't know folks.2 years ago I took a laptop which I wasn't using (16 GiB RAM non-ECC) => I created in Linux with Python an array ("bytes"? Don't remember exactly anymore) of ~10 or 12 GiB containing random integers => computed the array's hash and saved it.Then for ~1-2 months I recomputed from time to time the hash of that array (inbetween the laptop was in suspend-to-RAM) and compared it to the original result => it always matched, I never had any bitflips.I therefore doubt that the estimation of "1/256MB/month" is correct - I could not prove that, at least not with my laptop.
