Stardate 44429.6. Today we will be heading into the deep realms of logging... Wait not this is Log Captains not Captains Log. We will in instead a fun and interactive way look through a deceptively difficult problem in computer science, how to keep a log consistent across more than one machine. We will get in depth and look at the subtle problems that can occur in such systems and actually see the varying failure modes. We will even cover the algorithm of algorithms Paxos and how it works.Be not afraid of the algorithms for they will shed their secrets when tennis balls are applied! Yellow tennis balls!
