Stopping Entropy with ArchUnit
2019-05-08
So your team has agreed on naming conventions for classes and how to structure classes in packages. Last week you found out that a specific class is error prone to use. Writing this down in a Wiki will not allow for automatic checks. Tools that produce dashboards look nice at first sight, but will fall into oblivion soon.
My talk at Devoxx UK shows how to automate architecture rules and best practices as ArchUnit tests. It will compare ArchUnit with other tools to show limits and advantages of this approach.
Vue.js Aync Components with Loading Indicator
2018-05-06
At the Vue.js Frankfurt Meetup I’ve presented the benefits and caveats of asynchronous Vue.js components.
For now, there are only some slides. I plan to extend it to a proper blog post soon.
DevOps: Fast, reliable and safe delivery
2019-04-30
At the beginning of the century Nicolas Carr claimed that “IT doesn’t matter”. But today software delivers the services and products we consume, and every improvement requires changes to the software. Companies strive to test their new ideas faster and more reliable than their competitors. To do this, a company needs to re-invent its organisation, technology and culture for DevOps.
In our article in Informatik Spektrum Björn and me summarize who needs DevOps, how it works. We also detail the challenges and benefits.

Book Review: Made to Stick
2019-02-20
When you write, write for your readers, they say. But will your readers remember it? Will they even read the article to its end?
Chip Heath and Dan Heath answer the question why some ideas survive and others die, i. e. why they are being remembered or forgotten.

Hosting simplified by a CDN
2019-02-02
Last year I moved my personal website and our Meetup’s homepage to Netlify, a content delivery network (CDN). I was astounded about the minimal steps necessary make it work. It simplified both the setup and the day-to-day operations for me.
This article takes you through the minimal, yet real world steps to set up the homepage of the Vue.js Frankfurt Meetup with Netlify.

Book Review: The Tangled Web
2018-11-21
A good friend and colleague lent me this book.
Although the title “The Tangled Web” gave a different idea, the subtitle “A Guide to Securing Modern Web Applications” pointed to its security background.
It turned out to be a dive into the history and workarounds of the web!
Observability for Microservices
2018-11-04
To be able to identify and analyse problems, applications in a microservice environment need to provide standardized information to enable efficient operations. This talk presents four areas that are part of observability: status information, logs, metrics, and traces.

The next conference is near – on September 29th I’ll present a talk about Monitoring, Metrics and Spring Boot at the JUG Saxony Day in Dresden. The focus will be how to use Micrometer and Prometheus in your projects.
Book Review: Java by Comparison
2018-07-18
The full title reads “Java by Comparison - Become a Java Craftsman in 70 Examples”.
When I first heard of the book I was sceptical: Is there really enough common ground for 70 good code examples? Would the examples be the starting point of an argument if you would show them to a team of programmers? After a conference in Berlin, Simon offered me a free copy to read.
Dotfiles for crossplatform projects
2018-04-06
Whenever I start a new project, I like to check in configurations to Git, so that every other developer uses the same settings as I did. This also leads to more reproducible build.
This post summarizes the different files and their interdependencies.

2018-03-22

The cycle is now complete. There is a lot of material to read, watch and try-out!
Asciidoctor Deep Dive
2018-03-16
Asciidoc is a markup language for documentation. Asciidoctor is a popular implementation of a rendering engine for Asciidoc.
I’ve given a talk Asciidoctor Deep Dive at the JavaLand conference. I post the code samples, the slides and a video recording here.
In the talk I share my experiences with Asciidoctor, tips and tricks and hints to style your PlantUML diagrams. I also show how to get most out of Asciidoctor PDF generation using templates and extensions.
Microservices - more than a hype?
2017-10-29
For the German magazine Informatik Spektrum I wrote an article capturing the current ideas of microservices as an introduction.
It’s based on my project experience over the last two years. A free online-version of the article is available as well!
