jOOQ’s main value proposition is obvious: Type safe embedded SQL in Java. People who actively look for such a SQL builder will inevitably stumble upon jOOQ and love it, of course.

If you’ve read this blog before, you know that secure messaging is one of my favorite topics. However, recently I’ve been a bit disappointed. My sadness comes from the fact that lately these systems have been getting too damned good.

How would you describe retail in 2017? For some, it’s the year that marked the sector’s true transformation. Think of the Booker-Tesco deal that shattered formerly untouchable barriers, Amazon’s Whole Foods acquisition that gave the US giant a supply chain advantage that edges even closer to the customer, and brands like Dyson and Smeg who opened up their first ‘direct…

A good retrospective strengthens the team and creates a spirit of shared identity. Typically, retrospectives are held within a delivery team or a small team working on a specific topic. But sometimes, you have…
