Modules – Microservices – Monoliths

Microservices were supposed to solve every architectural problem conceivable. Not too surprisingly, that was not the case. Now themonoliths thatwe have been developing for decades are supposed to be the solutionagain. Inthis discussion, the foundation for developing complex software systems has been forgotten: Modularization, which is far more important than the question of monoliths vs. microservices.

Automated code maintenance with OpenRewrite (Part 1)

With the large number of software development projects in most organisations, keeping these projects up to date with the latest security patches and framework updates can be quite a task. OpenRewrite is a library that provides an automated solution to this problem. Using recipes written in Java, it can perform large-scale source code refactoring during the build process, preserving as much of the original code as possible. In this blog post, I will explain how OpenRewrite works and how you can use it to refactor your code base.

Kustomize Enhancement with KRM Functions

Round-robin coding

Remote mob programming typically means one person takes on the role of typist at the screen with an open IDE, more or less typing what the others tell them to. To ensure that everyone stays on top of the work, the role of typist is frequently changed up and the current state of the code is handed over to the new typist. Our simple CLI tool called mob enables such a handover in just a few seconds by bundling the necessary Git operations into concise commands.

How to use Apple Shortcuts to integrate GPT-4o in macOS and iOS

Apple Shortcuts is a powerful app that lets you create custom workflows with multiple steps using your apps and content. You can also use it to interact with web services and APIs, such as OpenAI’s Chat Completions API for GPT-4o, which can generate text completions for any prompt or task. Yup, the thing that’s behind ChatGPT.

Blueprints

JavaScript’s approach to object orientation is different from other languages. This hasn’t been changed by the introduction of classes, even if it looks that way at first glance. Read on to learn how this unusual system works.

Diverse Themen und Bibliotheken für Tests in und mit Java

In diesem Artikel betrachten wir bunt gemischt diverse Themen und Bibliotheken rund um Tests für und mit Java. Dabei folgen wir keinem roten Faden, sondern lassen uns durch das übergreifende Thema treiben.

What is Sustainable Software?

Shortcomings of ISO 25010

Published in 2011, the ISO 25010 standard on software product quality lacks pragmatism and practical applicability. Terms like scalability, deployability, energy efficiency, safety, or code quality are missing. This article explains these shortcomings and shows that even the (draft) update from 2022 still needs polishing…

How to use and build your own distroless images

Security and efficiency are key goals in production systems. This begins when we build our application images and look for a suitable base image. So what are good base images and how do distroless images fit into this picture?

How AI will replace my job

In late 2022, I decided to try to use ChatGPT, an AI language processor, to do some of my daily software development work. Now, only a few weeks later, I am convinced AI might soon do most of my current work, at least measured by hours.

How to prepare a (not only technical) talk

As I want to improve on giving valuable (conference) talks this year, I like to introduce my current four-phase approach to preparing these. Because when you intend to improve things, it is always a good idea to start with summarizing the current state. From there you can find out what is already good and where there is room for improvement. I would love to hear / read about your tricks and ideas!

Untangling the confusion between browser defaults and JavaScript component frameworks

Behaviour over structure

We, developers, often forget why we even exist. We quite often don’t remember that our purpose is not to write software, but to solve problems. Those come in different forms, but can be generalized as “we need to start doing this”, “we need to stop doing this” or “we need to do this differently”. Those “do” and “doing” are the key, whatever “this” is. It’s the behaviour our software exhibits that is most important, almost everything else is secondary.

Frontend integration options

The integration of data and functionality in the frontend is a powerful topic that is still rarely discussed. This article aims to try and show established patterns of frontend integration and briefly name possible advantages and disadvantages.

Helm und Helmfile

Für Kubernetes gibt es inzwischen für jeden Use Case ein passendes Werkzeug. Trotzdem ist es nach wie vor eine Herausforderung, reproduzierbare und gleichzeitig flexible Rollouts für Infrastrukturkomponenten und Anwendungen für verschiedene Stages zu automatisieren – ohne in der Scripting-Hölle zu landen. Helm ist ein geeignetes Mittel, wird aber erst zusammen mit Helmfile wirklich mächtig.

Processing medical study data with Data Mesh technologies

Together with our customer CluePoints, we evaluated new technologies, tools and standards for data storage, data processing, data versioning, and data lineage. These might become useful for refactoring their self-serve data platform.

Logging in Java

Logback, Log4j, SLF4J, and many more. Anyone working with automatic logging in Java will immediately come across an entire range of libraries that, at first glance, seem to do the same thing: issue log messages. So, in this article, we want to look at why there are so many libraries in Java and how they actually differ from each other upon closer inspection.
