Book: The Tangled Web. A Guide to Securing Modern Web Applications.

Book Review: The Tangled Web

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 Logo

Observability for Microservices

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.

Monitoring with Micrometer

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: Java by Comparison

Book Review: Java by Comparison

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

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.

Asciidoctor Deep Dive

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 Article in Informatik Spektrum

Microservices - more than a hype?

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!
