If you work in Computer Science, you are doubtless familiar with Murphy's Law, which states that whatever can go wrong, will eventually go wrong. Faith and prayer rarely help. And this talk is not just theoretical, stories of tech disasters in the NonStop Community prove this point again and again. Over the many years since Tandem was born in the 1970s the community has learned that data is really your most important asset, and without it we have no business at all.
