On June 21, 2017, I will give a talk about ‘Cleaner Code with Kotlin’ at the Clean Code Days in Munich. In my talk, I will discuss where Kotlin can help us to write Clean Code and where not. Besides, I will point out how we can get rid of Java’s bloated boilerplate and why we should be careful with some of Kotlin’s features. I’m really looking forward to this conference and I’m happy to be part of it.
On March 31 2017, my colleague Fabian and I gave a talk about ‘Kotlin in Practice’ at the first JUG Saxony Camp. This conference aimed at students and was organized by the Java User Group Saxony and the Leipzig University of Applied Sciences. It was a beautiful day with many interesting talks and chats with students!
In order to take full advantage of Kotlin, we have to revisit some best practices we got used to in Java. Many of them can be replaced with better alternatives that are provided by Kotlin. Let’s see how we can write idiomatic Kotlin code and do things the Kotlin way.
Writing documentation manually for a RESTful API can be laborious. On the other hand, relying exclusively on the generation of the documentation (e.g. with swagger-ui) is often not sufficient. There are always aspects (like common use cases and workflows) that need to be described manually. Let’s see how we can combine these two approaches with the help of AsciiDoc!
Wordpress bugs me. It slows down the authoring process and comes with security issues and maintenance efforts. That’s why I moved to Hugo. Hugo is a static website generator and allows me to write effectively and offline. In this post, I show my reasons for moving from Wordpress to Hugo and point out tips and tricks for the migration.
Today I delivered a guest lecture at the Chemnitz University of Technology at the chair of Distributed and Self-organizing Systems. The lecture revolved around microservices in practice at Spreadshirt.
Coding with Kotlin is great fun. But things are getting really interesting when we try to use Kotlin in conjunction with popular frameworks like Spring Boot and Vaadin. The development with those frameworks can benefit a lot from Kotlin. However, we have to pay attention to some pitfalls.
We at Spreadshirt have started to use the JVM language Kotlin in a couple of services. This ended up in great enthusiasm. Kotlin allows us to significantly reduce the boilerplate and to write more robust and readable code. In fact, I don’t want to write Java anymore. In this post I like to show you why.
I’ve worked with Eclipse for 7 years. Now I switched to IntelliJ IDEA and I’m extremely happy with this IDE. To my mind IntelliJ IDEA is definitely superior to Eclipse. In this post I show you why.
A typical Jenkins 1.0 setup for Continuous Integration (CI) comes with some drawbacks. The job configuration is stored somewhere else but not in the version control system. This makes it hard to set up a new job correctly or to track configuration changes. Another pain point are the various tools (JDK, Maven, node, gulp etc.) that have to be installed and maintained on all Jenkins nodes. This increases the maintenance effort and can slow down the development. Let’s consider some solutions for these issues.
