However, the challenge lies in finding appropriate boundaries for the areas of responsibility of these teams. This is the focus of this article.

One of the main tasks that business sets for IT as an industry is the creation of effective software, according to criteria that clearly meet the needs of this business. On the other side, one of the main prerequisites for achieving the goals that a business sets for itself is the ability to hire specialists who can create a product in the shortest possible time and/or effectively maintain it. Accordingly, to achieve this, the technology stack used, i.e. tools, must be mature enough, and widely used in the market.

Was ist eigentlich htmx?

Nicht nur, aber vor allem im JVM-Umfeld stößt man in letzter Zeit immer wieder auf die Bibliothek htmx. Das Versprechen von htmx ist dabei nichts Geringeres, als das fehlende Puzzlestück von HTML zu sein. Deswegen wollen wir uns hier diese Bibliothek im Detail anschauen. Schließlich sollten wir in der Lage sein zu beurteilen, ob es uns in unseren Projekten hilft oder ob wir doch nach etwas anderem suchen sollten.

API gut, alles gut

Unternehmen streben häufig eine Modularisierung (wie durch Microservices) an, die Teams unabhängiger voneinander arbeiten lasst. Dabei ist aber ein reines Aufteilen der Applikation in verschiedene Module/Container/Bausteine nicht ausreichend. Die Abhängigkeit oder Unabhängigkeit entscheidet sich vielmehr mit der Gestaltung der Schnittstelle, genauer: Mit der Frage, ob die gewählte Schnittstelle fachliche Implementierungsdetails preisgibt oder diese versteckt.

Automating Dependency Updates with Renovate

Regardless of whether we are working on an application or a library, we always have to deal with dependencies. We are dependent on the version of our programming language, on external or internal libraries, and on tools. In addition to the actual administrative tasks, it is also necessary to update these regularly. Even beyond performing the update itself, this means we need to learn when a new version exists. That’s why this article examines a bot-based solution that can help us with this exact issue.

Technologies for the Integration of Services

In the course of an internal study, we asked a number of INNOQ consultants about their experiences in current or past development projects. One interesting topic here was the integration of microservices and self-contained systems (SCS). Asynchronous communication is frequently used in distributed systems to enable better scalability, greater resilience, and looser coupling. In this article, you will read what insights we learned in our conversations.

Entwickeln mit ChatGPT

In der Welt der Softwareentwicklung ist das Wissen darüber, wo man Informationen findet, oft wertvoller als alles auswendig zu wissen. Doch was, wenn ein Werkzeug nicht nur Informationen liefert, sondern auch lernt, Probleme zu lösen und beim Entwickeln zu assistieren? In diesem Blog Post berichte ich aus meinem Alltag als Entwicklerin und wie mich ChatGPT bei beruflichen Aufgaben unterstützt - sei es bei der Einarbeitung in neue Programmiersprachen, dem Schreiben von Skripten oder dem Umsetzen von kreativen Ideen.

The Evolutionist

The current training and further education of software developers strongly focuses on the development of new software. Conferences and trade magazines are full of new programming languages, new tools, new hypes, which seemingly never cease to amaze. Quick results, direct feedback, and unprecedented productivity are suggested. The urge to incorporate the new into one’s software is awakened – until one is brought back to reality: their own legacy system.
