When you work with git you can define aliases to make your experience even more productive and elegant. In this short post I’d like to present aliases that I use frequently and how they work. And I’ll start with my favorite: git recent-branches.
When you design a class you should never design it in a way that the class itself knows how it is used from the outside. Breaking this principle will make it difficult for other developers providing other implementations. I recently stumbled upon an implementation of different entities where the implementation had to provide a unique id for itself. Why this is causing problems and how you better design such a situation I’ll explain in this post.
In my current project we use Bitbucket Server as our Git backend and Jenkins with a pipeline multibranch project to build our project. For better integration of both technologies we decided to use the Bitbucket Branch Source Plugin. This enables us to trigger automated builds and maintain dynamic jobs on our Jenkins. But installing the necessary webhooks turned out to not be a trivial task.
This blog is not very old yet. I just started it a month ago and of course I wanted to know if somebody is even reading it. So after a few days I included Google Analytics to get an impression of the visitors of my page and if I even have an audience here. But barely any visit got tracked and since I didn’t even filter out my own ip I had the impression that I’m basically the only user of my page. But that impression was wrong, which I noticed when I switched to server side tracking.
After answering a question on stackoverflow about how to configure Spring Security with your own authentication mechanism I’d like to go into more details in this post. I’ll implement a simple use case where the actual authentication is done by reading the username and password from the header of a request.
I use the declarative Jenkins pipeline in my current project, but after 2 years of development we hit a barrier I wasn’t aware of. Jenkins puts the whole declarative pipeline into a single method and at a certain size the JVM fails with java.lang.RuntimeException: Method code too large!. Digging deeper it turns out that no method is allowed to exceed 64k. So I needed to find a solution for this problem.
