Built To Last: Computer Systems That Simply Cannot Fail

From ExtremeTech:

A failing computer system can be a problem in some settings, but it's catastrophic in others. No one likes when their computer crashes out while in the middle of an overnight render, but the cost of that delay is nothing compared to a failure in a mission-critical environment, such as in a hospital, on a satellite, or, in the case of Curiosity, on another planet entirely. These extraordinary settings have led to the creation of specialized computer systems that are designed to work in high-demand situations, often for years on end. They are, not surprisingly, some of the most interesting computer systems out there.
