Is Scrum Democratic?

Hi, Is Scrum democratic? This question keeps coming up. Time and time again, I find myself in teams where this question becomes the focal point. The keyword that often comes up is “self-organized team.” How much autonomy does a self-organized team have? Undoubtedly: The team organizes its work on its own. The Product Owner decides which tasks are to be tackled and in which order. And he is a part of the team.

Redundant Information

Hi, “After importing, we unpack the file and read the meta-information.” “And where do we write it?” “This information is stored in different databases. The path information is distributed across all service databases so that they know how to access the files. Other data is stored in the system database and in each tenant database.” Does that sound normal to you? It shouldn’t. What we are experiencing here is information duplication. “But Marcus, why is that so bad? We just need the information in different places.”

Editor Fluency

Hi, Today, I gave a presentation titled “Pragmatic Programming with Kotlin” at KKON. It was once again a great pleasure. And because the RabbitMQ Summit is coming up this Friday, followed by the W-JAX in two weeks, I really didn’t feel like creating more slides. So, I opted for live coding. That way, I’m certainly faster in preparation (tm). But aside from my laziness, there was another reason why I chose to do this.

Deliberate Practice

Hi, Currently, I am practicing calligraphy. My handwriting has always been purely “functional.” Every day, I write out all the letters of the alphabet, focusing on the quality of each stroke. Five years ago, I practiced touch-typing. Every day for 10 minutes on https://www.keybr.com/ . Seven years ago, I banished my mouse within the IDE. I had to learn how to operate everything using the keyboard alone. And ten years ago, I focused on the Shell. I performed all operations on my system there.

Java 21 is GA!

Hi, Java 21 has finally reached General Availability (GA) status since Tuesday 🎉 For months, I’ve taken every opportunity to talk about how virtual threads are the highlight of this release for me. For instance, in this or this old newsletter. And that hasn’t changed. I believe virtual threads are one of the most significant improvements in years. Whether everything turns out as expected remains to be seen. But of course, there are also other features that shouldn’t go unmentioned.
