Evolving software like an orchardist

Software systems are usually larger, overgrown structures that developers need to bring back into shape after some time. However, creating an overview of the sprawling conglomerate of software components is challenging, let alone developing a clear plan for moving on. This blog post uses analogies from pruning apple trees to show developers how to evolve their software systems using a value-based approach.

Draw The Diff

Software developers have an idiosyncratic penchant for boxes and arrows. Back when we used to go to the office we penned them on whiteboards. Later, as the force majeure accelerated the digital transformation of our economies, we drew them online.

An Introduction to TLA+ and Its Use in Parties

TLA+ is a system for modeling all possible states of a system. On this model, you can then verify certain properties of this system. Smart people can use this to check that their thread scheduling runs all threads equally, or that their work queue will never overflow. In this article, we’ll try and verify the fraught process of ordering pizza for a pizza party as a small introduction to the concepts and syntax of TLA+.

Automated code maintenance with OpenRewrite (Part 2)

In part 1 of this series, I showed how OpenRewrite can be used to automate code maintenance tasks for software development projects in your organisation. In this post, I will demonstrate how to write your own OpenRewrite refactoring recipe. This will not only help you to perform refactoring tasks for which no recipe is publicly available, but will also deepen your knowledge and understanding of how OpenRewrite works under the hood.

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.

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.

Container-Images mit Buildpacks erzeugen

Im Rahmen dieser Kolumne habe ich mich schon häufiger auch mit Containern und Docker beschäftigt. Obwohl es sich hierbei weder um ein Java- noch um ein direktes Entwicklungsthema handelt, ist es für viele Projekte von hoher Relevanz. Schließlich spielt heute auch der Betrieb von Anwendungen für die meisten Entwicklungsteams eine hohe Rolle und dieser nutzt aktuell in vielen Fällen Container. Hier wollen wir uns mit Buildpacks eine weitere Möglichkeit im Detail anschauen, um zu einem Container-Image zu gelangen.

What is Sustainable Software?

Environmental sustainability is a very important issue, but software is something virtual, so it doesn’t seem to have an impact, right? Wrong! As software creators, we have a significant impact and can make a difference by incorporating the principles of eco-friendly software development into our understanding and practices.
