Mutation Testing badge with Pitest and Stryker Dashboard
Over the years, badges have become a way for open source maintainers to show the state of their product. Badges can give a quick overview of the code quality, test coverage or build health of an open-source product. The problem with code coverage is, however, that a high coverage doesn’t mean the tests are any good. If only there was a way to show the quality of the test suite…

Setting up new infrastructure can be a tedious process. It doesn’t matter whether it is on-premise or in the cloud. Many organisations have a long process of filling forms, obtaining budget clearance, asking for priority and verifying everything is set up correctly. The cloud promises us to make things better, and at least it got a lot faster. But still, we can make many mistakes in this manual process, and if we want to duplicate a deliberately crafted setup things become even harder….

Together with four “AwesomeSauce” colleagues from Info Support, I’m attending DevNexus this year. For me, it’s the second time I’m here, as I spoke here in 2018, too.

This year I’m returning to Devoxx. I’m planning to write some notes on interesting sessions or other content. Also, I’ll be delivering my talk on Transport Layer Security tomorrow. But today was a day of catching up with old friends and attending a talk or two.
One talk really caught my attention: “Implementing a simple JVM in Rust”.

If you’ve followed recent developments in the Java ecosystem, you must know GraalVM. Many blog posts cover how you can build native executables from Java source code. This is indeed exciting: your program starts faster, and consumes less memory. Other popular topics include building Java applications that run code in other languages. You can run JavaScript, Python, Ruby or R code in the JVM. But there’s more: in fact you can run any language inside the JVM! Are you curious how? Continue reading…
