Software perfection

Edward A. Dauer
You do exactly that every time you fly (commercial).

But it didn¹t stop me either.  That¹s what the humans are for.

Re: Software perfection

Mike Markowski-2
Straight out of college I was one of 100+ design engineers on the Mode-S
FAA air traffic control system - multiprocessor, fault-tolerant system,
etc.  The design docs (let alone software) filled volumes.  Much as I
hope there were zero bugs in the complex system, it was after all
designed by people...

One thing I recall is that the FAA contract permitted 1 second of down
time per year.  :-)

73,
