Blogumentation Revisited

Leider ist der Eintrag nur auf English verfügbar.Some time ago I wrote about a process called "blogumentation": Derived from the insight that arguably the best way to learn something and to internalise knowledge is to write about it and to try and explain that knowledge to others, blogumentation essentially means writing about a subject matter (e.g. a solution to a particular programming problem or a new practice you've just learned about) that you consider worth documenting and publishing the result. It means ...

CORS: What It Is and How It Works

Leider ist der Eintrag nur auf English verfügbar.Expanding on last week's article on best practices for REST API Design I'd like to point to a specific aspect working REST APIs frequently entails: A browser security feature called "Cross-Origin Resource Sharing (CORS)". This feature allows you to define which resources provided by a web application are supposed to be accessible from which origin, which in turn typically is comprised of protocol, host / domain name and port.

A Simple Yet Powerful Tool: Decision Tables

Leider ist der Eintrag nur auf English verfügbar.Decision tables are a tool for specifying which actions to perform given a number of conditions. They represent business logic in terms of rules for connecting actions with required conditions for those actions. While they might appear deceptively simple and trivial they can be a tremendously powerful tool for defining business logic and certain types of software requirements. This article on Decision Table Patterns by Hillel Wayne describes the general concept as well as patterns, ...
