In order to collaborate, a system of rules is required that affords good hygiene, fault tolerance, and effective communication to coordinate, share knowledge, and provide trusted feedback. These rules form a number of protocols which enable the group to act as a system that is greater than the sum of the individual components. Protocols provide the foundation on which the quality attributes of a system are delivered. Qualities such as performance, resilience, and security. In this talk we will explore the history of protocols [...] Download slides and read the full abstract here: https://gotober.com/2019/sessions/889/interaction-protocols-its-all-about-good-manners TIMECODES 00:00 Introduction 00:27 Interaction Protocols 03:19 How significant are protocols for software development? 05:02 Evolutionary Biology & Communication 05:19 Facial Expressions 06:03 Manners & Etiquette 06:34 Hygiene Disease 08:04 Courtesy Society 09:02 Formal Protocols 10:02 Good conditions to succeed 10:32 Concurrent & Distributed Systems 10:57 How should components Interact? 12:07 418 "I'm a teapot" 13:57 How should we document our protocols? 14:07 API vs Protocol 15:57 What could possibly go wrong? 17:13 Multicast Example 20:02 ACK / NAK Implosion 24:41 Who cares about waste? 25:17 Don't use text codecs!
