Currently, I am dealing with a bug that leads to unstable build times. The setup consists of Jenkins, Maven and the Surefire Test plugin. Through this work, I’ve come across the fact that all the optimizations we use on our developer machines never found their way into our Jenkins pipeline. So then I started tuning […]

My current itinerary for the event Monday Tuesday Wednesday – Distributed data management in a microservice architecture – The Basics of Machine […]
About two years ago I rolled out the first productive Spring Boot application within OpenShift. One of the problems we met back then was opening HTTP sessions even though we only rolled out a stateless REST server. A few days ago, there were problems with another REST service.

Last week I received a project laptop update. From 2 CPU cores it went up to 4 cores. Also the rest of the equipment suggests that the build time should be reduced significantly. But build time did not change at all on the new laptop:
A few weeks ago I took part in the DevOxx UK Deep Dive Session Parallel and Asynchronous Programming with Streams and CompletableFuture hold by Venkat Subramaniam (@venkat_s). I did write a lot of notes. So here they are 😀
On Tuesday my desktop system killed itself, just doing restarts before even BIOS / UEFI was loaded. The system did its job in playing some games on minimal settings as the system was quite old. The NVidia Graphic Card sometimes blacked out, but a restart could fix it. So now that that system is dead […]
On may the 5th the Devoxx UK conference ist starting. As I will attend the conference, it was time to choose the right sessions.
