This is a documented case of a bit flip, not a bit flip from a cosmic ray. I'm still skeptical that cosmic rays actually cause issues for computers inside earth's atmosphere.
- devwastaken 5y agoIf you want to learn about it I'm sure there are dozens of research studies that go over it. ECC is expensive, and so is the efforts gone through to reduce "cosmic ray" interference. Generally those costs, in the software world, have good measured reasons for their existence.
- gtujbkoj 5y agoParent is saying that bit-flips are not necessarily generated by cosmic rays, not that they don't exist. RowHammer is a good example - bit flips which can be triggered through specific memory access patterns.
- datameta 5y agoI don't believe a row hammer attack can be precise enough to target a single bit.
