The Space Shuttle software?
They Write the Right Stuff
But how much work the software does is
not what makes it remarkable. What
makes it remarkable is how well the
software works. This software never
crashes. It never needs to be
re-booted. This software is bug-free.
It is perfect, as perfect as human
beings have achieved. Consider these
stats : the last three versions of the
program -- each 420,000 lines long-had
just one error each. The last 11
versions of this software had a total
of 17 errors. Commercial programs of
equivalent complexity would have 5,000
errors.
