Well, for starters there are two well engineered solutions pre-built and battle tested that can be applied to arbitrary problems, by HN readers, now. Further, instead of the "build the perfect system" philosophy put forward in the presentation (ie. formal analysis), both solutions use the alternative "tolerate and control for failure".
