Pieter Hintjens presents a decade of research and practice in designing protocols using cheap experimentation, exploring of new avenues, and smooth accumulation of gradual change, driven by real use.
Pieter Hintjens founded the ZeroMQ community in 2007, and over 30 of his RFCs drive that ecosystem. In 2007 he also founded the Digital Standards Organization (Digistan), which defined legal templates and processes for decentralized protocol development.
Software is Changing the World. QCon empowers software development by facilitating the spread of knowledge and innovation in the developer community. A practitioner-driven conference, QCon is designed for technical team leads, architects, engineering directors, and project managers who influence innovation in their teams.
Points I found useful for me
2. 2 kinds of data - high volume, low latency and almost never changes; another low volume, latency not an issue and change all the time - business kind. First may use fast binary encoding. Second may use json and whatever.
Other stuff - about evolving protocols, testing, collaboration, writing contracts, cost of design.
