Hexagonal Architectures: @Column(nullable = false) vs @NotNull in Java Applications

Leider ist der Eintrag nur auf English verfügbar.Recently, I came across a small and common, but all the more interesting, hands-on example of why a hexagonal architecture can help with making both the architecture and the code of an application more understandable, approachable, and maintainable. I won't be going into any details about the concept of and ideas behind hexagonal architecture here. The gist is summarised quite nicely in this quote from Tom Homberg's article on Hexagonal Architecture with Java and Spring: The ...

A few random thoughts on the development of software development in recent years

Leider ist der Eintrag nur auf English verfügbar.Last year, I replied to Tom's question "Has software development grown harder over the last years or have I just grown sluggish?" on Twitter with these incoherent ramblings of a greybeard, who has seen at least 3 fat-client-thin-client cycles: As usual it depends. Just a few examples: Spring Webflux and the "Everything has to be reactive even if the requirements don't demand it." fad is a bane. Just recently, I've been helping a client with getting ...

Excalidraw: Shapes for UML & ER Diagrams

Leider ist der Eintrag nur auf English verfügbar.Excalidraw is a fairly new (having started in January 2020) virtual whiteboard software for creating diagrams with a hand-drawn aspect. I really like the aesthetics of diagrams created with Excalidraw. They have a natural feel and elegance to them. However, when recently revising some of the diagrams for Stratospheric – From Zero to Production with Spring Boot and AWS I found Excalidraw to be lacking shapes for UML & ER diagrams. I know, not everyone is ...

A Catalogue of Design Patterns

Leider ist der Eintrag nur auf English verfügbar.Recently, I came across this well-structured as well as visually appealing catalogue of software design patterns on Refactoring.Guru. The subject of design patterns can be a somewhat dry, unwieldy one. Hence, using visuals and metaphors can come in handy when explaining both the general idea behind design patterns and specific patterns alongside with their use cases. Refactoring.Guru does a great job not only at explaining the origin and purpose of and rationale behind design patterns and ...

Towards More Considerate and More Collaborative Code Reviews

Leider ist der Eintrag nur auf English verfügbar.Software engineer Dan Goslen recently published an article on how he's going to change his approach to code reviews. The most widely used organizational pattern for conducting code reviews probably is the pull request, also called merge request. This particular pattern and the tools source code management systems provides us with to support this pattern lend themselves to a review strategy that focuses on commenting on code and minute details rather than the big picture ...

Second-order Affordances: Design & Quantum Superposition

Leider ist der Eintrag nur auf English verfügbar.A few years ago, having read a thought-provoking article by Csongor Bartus I wrote about design & quantum superposition. The main idea behind this article, and my interpretation, is that - similar to a particle, which exists in a state of quantum superposition - a design doesn't exist by itself but can only ever be realised in a given context and at a specific moment through observation by a user and possibly a ...
