[erlang-questions] let it crash erlang/ada [[was: Time for OTP to be Renamed?]

[Richard A. O'Keefe]

Hardware redundancy is a great way of handling hardware
failures, as long as they don't have a common cause.
An over-voltage might take out several devices.  Discs
have an uncanny tendency to fail close together.

Triple Modular Redundancy goes back to von Neumann, 1956
(http://www.nunoalves.com/papers/IEEEpotentials10/IEEEpot10-transient.pdf)
It's good at dealing with single transient errors (radiation hits part
of one device but not the others).

Independently developed versions of a software component
are as a rule developed by people who tend to think in the
same ways and make the same kinds of mistakes.
