Presented at JAX London 2013 Community Night
Through some famous quotes and pictures that will make you think, Guillaume Laforge, Head of Groovy Development for SpringSource, will illustrate some simple principles that he has followed on the projects he’s worked on, and walk through the lessons he’s learned throughout the journey.
