J-Fall 2021: Hari Rangarajan – Reactive programming using RSocket

Organisation: Please excuse us for the inferior quality of the screen recording. A standard approach to connecting and communicating with microservices is needed.

J-Fall 2021: Jaap Coomans – Everything you never wanted to know about Maven versions

J-Fall 2021: Jan Ouwens – Just enough Computer Science for the busy developer

I studied Computer Science so you don’t have to! A CS degree is not a requirement for software developer roles. Nor should it be! I have worked with biologists, psychologists, and even a historian, who all were excellent coders. And that’s great! Diversity of thought leads to better software, after all.
