- Back to basics: accessing Kubernetes pods
-
Kubernetes is a colossal beast. You need to understand many different concepts before it starts being useful. When everything is set up, you’ll probably want to expose some pods to the outside of the cluster. Kubernetes provides different ways to do it: I’ll describe them in this post.
Despite a bit old, I think the post is still relevant.
- Detaching GraalVM from the Java Ecosystem Train
-
- The GraalVM team are transitioning to focus on non-Java Graal Languages including GraalPy and GraalJS. Details are expected to be announced later.
- GraalVM for JDK 24 was the final GraalVM release licensed and supported as part of Oracle Java SE Products. Customers requiring further updates to legacy GraalVM versions should download them via Oracle Support.
- Oracle JDK 24 was the final release to include the experimental and optional Graal JIT.
- GraalVM Early Adopter technology, including Native Image, is being discontinued for Java SE Product customers. The goals of improving the startup time, time to peak performance, and footprint of Java programs are being pursued further in OpenJDK’s Project Leyden as a standard part of Java.
This one can be open to so many interpretations that I’ll avoid commenting. Wait and see.

- Twelve years of blogging
-
In the early days of Twitter, I focused on two blogs: Petri Kainulainen's and Vlad Mihalcea's; the former focused on testing, and the latter on JPA. I don’t see Petri’s posts anymore (I’m happy to see he’s still blogging), but I still stumble upon Vlad’s. They are always very interesting to read. Even better, we met a couple of times and I’m happy to count him as a friend. Icing on the cake, he speaks very good French!
- Documentation
-
Lots of good advices, but I’m far from sure about the AI-related ones. Call me old-fashioned, but for me, the reference site for documentation is still The Documentation System. Granted, it focuses on a much higher level. They aren’t actually exclusive.

The post makes an interesting point, but this part strikes a particular chord in me:
Even if the big technical debates do have definite answers, no working software engineer is ever in a position to know what those answers are, because you can only fit so much experience into one career. We are all at least partly relying on our own personal experience: on our particular set of engineering values.

Interesting read. However, if I need to try convince my whole hierarchy about the soundness of my decision, I feel like I’m wasting time. I’m amazed by people who do this as their job, and I’ll definitely be very supportive of any boss who does this for me.
