    This seems pretty cool. Is it basically about adding 9s?

      9s is really just shorthand for reliable

        Sure. Have you read it and can you give a summary of it? Several people have upvoted, so presumably the content is pretty good, but I couldn’t get a good handle from the abstract on exactly what it’s about. It says it’s about making your software reliable even when you have a software error, which sounds to me like using parts that have not so many 9s* in clever ways so as to add 9s to them. Is that what it’s about? Does he have interesting points on the topic, or is generally what you would expect?

        *If you wish, replace “have 9s” with “is reliable” everywhere.

          Its fairly long and I don’t feel comfortable trying to boil down.

          The rules it lays out are embodied in the OTP libraries that ship with Erlang. If you have a familiarity with them, then you would have a practical exposure to the ideas.

            Hmm, I don’t, although that sounds interesting. Thanks, I’ll put it on my read it later list.
