1/9 It sounds like a cliché 🙄, but software features are like the imaginary iceberg. Only a small part is the initial contribution, which is easily visible from a distance. But most of it is the hidden part of the ongoing maintenance.

1/4 A few weeks ago, I noticed that one of the #Strimzi refactorings that was done earlier this year did not have good unit test coverage, and I made a note about it in my TODO list. It was sitting there for some time as a very minor, unimportant issue.

Chat Control is back! 😶
Today, the Council of the EU without further debate advanced a revised CSAM regulation. After widespread protests, mandatory scanning of all messages was removed from the draft law, but much remains.
What then is in the latest version of Chat Control? 🧐

If you use #Strimzi for local #ApacheKafka development with Minikube or Kind, Keksposé is the perfect tool for exposing your Kafka cluster locally and making local application development easy. If that sounds useful, go and try it out: github.com/scholzj/keks...

When you spend too much time in the Java land, boxed primitives such as Boolean or Integer might seem like a great thing. But then you try to use an API built on them in Go. And that is when you realize what a bad idea it was.

Ok, the original proposal was maybe a bit premature. But I opened a new one that is covering more different things and approaching it from a bit more complex perspective. Surely, this one will be the real deal: github.com/strimzi/prop... 😉

1/2 In December of 2023, I wrote a blog post about our progress towards #Strimzi 1.0.0: strimzi.io/blog/2023/12.... I said there that it is unlikely to happen in 2024. Sadly, I can now say that it will not happen in 2025 either. 😞
Where is Strimzi 1.0.0?
Strimzi provides a way to run an Apache Kafka cluster on Kubernetes in various deployment configurations.

1/3 Today was the last day of my 6 months off from work. I spent it mostly by walking, traveling, reading, binge watching TV shows, and stuff like that. It might seem like I wasted six month of my life. But I found it great to be able to switch off and do "nothing" all day long.

Have you ever wished you could enable interactive delete, by default, in kubectl? Or maybe, you'd like to have custom aliases defined, but not necessarily generate hundreds of them manually? Look no further....

I wanted to test #Strimzi authentication with SASL AWS_MSK_IAM against #AmazonMSK. But after an hour of trying to setup an MSK cluster that I can access from my home lab I gave up. I guess either I'm getting old or AWS UX is even worse than it used to be. 🙄
