Space is really cool. From precision electronics, to giant rockets, spacecraft can represent the best of engineering. But sometimes things go wrong. Terribly wrong. What do exploding Soviet rockets have to do with Agile development? How did LISP and Forth hacking save part of the Galileo probe? What about that time astronauts added life-saving monkey patches... while orbiting the moon! Exactly how much damage can a little dead code do? (Hint: a lot!) This talk is for anyone whose love of a good space story is rivaled only by their passion for incredibly resilient software.
