Reminds me of the possibly apocryphal story of the missile whos guidance system had a memory leak.
They profiled the memory leak and gave the chip enough RAM that it wouldn't fill up before the missile exploded. Problem solved!
- thfuran 4y agoThere are in service commercial planes that need to be routinely rebooted to prevent counters from overflowing, so I really wouldn't be surprised about similar sorts of issues in single use devices.

- saltcured 4y agoEarly in my career, before "turbo" or "boost" frequencies were a thing in commodity CPU products, I heard a similar tale about boosting the speed of the signal processors in a defensive radar system. The thought was that you would rather overheat and perform the calculation than protect the circuit and lose the ship. It's kind of a hail mary strategy. It definitely gave me a visceral feeling for how one should be ready to re-frame their systems analyses, even if apocryphal.
