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

Leider ist der Eintrag nur auf Britisches Englisch 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.

(English) Second-order Affordances: Design & Quantum Superposition

Leider ist der Eintrag nur auf Britisches Englisch 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 ...

(English) REST API Design: Best Practices

Leider ist der Eintrag nur auf Britisches Englisch verfügbar.It's probably safe to say that REST (REpresentational State Transfer - originally described by Roy Fielding) is the most widely used architectural pattern when it comes to APIs in web application contexts. From statelessness, to self-descriptive messages, and hypermedia as the engine of application state (HATEOAS) REST comes with quite a few principles, constraints, patterns, and flavours, not all of which are used or applied consistently with each REST API.
