In a previous blog we described how we used JUnit and Reflection to verify correct implementation of coding standards addressing Axon Upcaster consistency. We concluded that, although possible, it felt a bit like a hack because we had to change modifiers of Java variables defined as “private static final” resulting in Java security manager warnings. […]
Spring I/O 2019: a Trifork report
In 2010 I spoke at a new conference that Sergi Almar was organizing in Madrid about Spring. At that time it was mostly focused on Spanish attendees, and quite small. Over the years the conference grew larger and larger, moved to Barcelona and became the biggest community-driven Spring conference in Europe, and probably the world, […]
Top take-aways from TEQNation
Last week, on May 15, I had the pleasure of attending the TEQNation conference. While I had been to this NLJUG event before, it felt like my first time again. Not only because of the amazing new location—the industrial chic De Fabrique—also because it’s my first time attending as a budding programmer. Although, given the […]
Double proud
Silence before the storm moment. 0800 on our new 3rd floor, all fresh, all new. The room for the masterclass was ready, tables, chairs and as we’re in Amsterdam: lots of coffee. Test the projector, plenty of post-its, all sharpies in place. The start of a masterclass that we do more and more: explaining Artificial […]
Unit Testing Source Code: Verifying Axon Event Upcaster Consistency
In our last project we used a JUnit test to check consistency of all code concerned with Axon event upcasting. We think this is interesting as we basically unit test source code rather than class behavior. In this blog we describe how we implemented it and conclude with a short evaluation and we list alternative […]
Game of Thrones Network Science
“Did you know? You are just six handshakes away from meeting the President of the USA.” I am not sure when I first heard this statement, but it sure is a captivating premise. I have heard it many times since, cited as a fun-fact at family birthdays by semi-knowledgeable uncles or as super inspirational introductory […]

Experience Magenta
“Can you help my VP to better understand the importance of people over tech?” Interesting question from one of my old managers. Sure, if I can help, happy to have a coffee. Interesting setting, outskirts of Cologne, Germany. New building, all ornaments pink. Pink like my gin. We started with a coffee, and I asked […]
