SPEAKER: François Martin   COMPANY: Karakun

KEYWORDS: Lessons learned, Technology, Tools

Over years of working with many Java codebases, I see the same mistakes being made over and over again when it comes to using Streams.

Implementierung von DDD leicht gemacht mit Spring und jMolecules

SPEAKER: Stefan Heinzer   COMPANY: ELCA Informatik AG
