- On PowerMock abuse
-
While Simon Martinelli writes about Mockito (see below), I warned about PowerMock ten years ago. The more powerful the mocking tool, the worse the code testability can be. Ergo: keep the mocking tools as simple as possible, or even better, don’t use any if you can, to design testable code from the ground up.
- Spring Team on AOT Cache Handling, Null Safety with JSpecify, and Support Durations
-
The idea of providing AOT-code along with the app to improve start-up times is getting more and more popular. I wonder what’s the burden of creating and delivering such cache vs. the performance improvement. I guess that the easier the process to create and deliver the cache, the more companies will adopt it.

I understand more or less the grid layout. With the video, I could understand subgrid. But the resizing sorcery at the end is definitely beyond my current understanding.

- Why I Don’t Use Mocking Frameworks and Why You Might Not Need Them Either

When I wrote Integration Testing from the Trenches, I described mocking a lot and in detail. However, I admit that TestContainers changed the game a lot!
- How to deal with (Rust) dependencies
-
In the article, the author lists three "good" reasons you should include a dependency:
- Dependencies that do something you don’t want to do yourself
- Dependencies that act as the canonical interface to some system facility or hardware device
- And for Rust, "Safety quarantine" crates that wrap some unsafe features in a safe wrapper
That’s a good checklist whenever you want to add a dependency to your project. Don’t add a dependency for a single function.
- Weaponizing Dependabot: Pwn Request at its finest
-
I’m amazed by the creativity of these attacks.
I’m using Renovate instead of Dependabot. So far, I didn’t configure it to auto-accept Pull Requests. This post is another reason not to do it.

- Why Senior Developers Google Basic Syntax
-
I feel seen. Lately, I had to pass a coding challenge on an online IDE that had no auto-completion. Instead of using the Kotlin or even the Java API, I had to fall back to muscle memories of years of managing indexes on collections. It worked, but the experience wasn’t pleasant, and I wasn’t happy with my code, even though it worked.
- Frustration-Free K8S for Spring Developers

Apart from the interesting talk:
- TIL: Service Binding for Kubernetes. I never heard of it before. It’s implemented by Spring Cloud and Quarkus.
- Tilt: I heard about it, but I had never seen it in action. Seems like it’s pretty powerful, but also quite complex.
