How does one defend against cosmic rays?

Keep two copies or three like RAID?

Edit: ECC ram helps for sure, but what else?

>How does one defend against cosmic rays?

Unless you are in the extremely small minority of people who would actually be affected by it (in which case your company would already have bought ECC ram and made you work with three isolated processes that need to agree to proceed): you don't. You eat shit, crash and restart.

		Well, bitflip errors are more of a vulnerability for longer lived values. This could effect fukushima style robots or even medical equipment. ECC implemented outside of ram would save vs triplicate but it was just a question related to the-above idea of an array access being assumed as in+bounds. Thank you.

You run equivalent or equal calculations simultaneously on N computers and take majority wins, aircraft control or distributed filesystem style.
