The Importance of Communication in MVP Product Design

|

Successful collaboration requires great two-way communication.  That sentiment is core to our product design philosophy here at Chariot Solutions.

Enabling REPLs and conversations with Spring Boot using Spring Shell and JShell

|

Earlier this year at PhillyETE, we had a great talk by Avdi Grimm and Jessica Kerr, REPLs All The Way Up: A Rubric For Virtuous Feedback Loops. In this talk, one of the key theses was to find ways to make exploring your code easier, via REPLs, scenario setups and other means. Many years ago I used to mount the BeanShell servlet and export my Spring Context so I could write little scripts in a web page in a Spring…
