J-Fall 2018: Kenny Baas-Schwegler & João Rosa – From EventStorming to CoDDDing

To really understand what our users need so that we can build the right thing, we want to have a first-hand experience of ‘real-life stories’ before we model and create our software.

J-Fall 2018: Peter Hilton – Flat HTTP API Documentation

The way we write API docs is highly structured, natural to programmers, and wrong. HTTP API documentation typically looks nothing like the requests and responses it describes.
