How a Strong Type System Saves You Documentation, Tests, and Nerves

How a Strong Type System Saves You Documentation, Tests, and Nerves

I was recently inspired to finally write this post. Especially in weakly- or untyped languages, such as the JavaScript or PHP world, the added value of strict type systems is often not recognized. Instead, many discussions and comments revolve around the need for tests or code comments. Contrary to that, in the functional programming world, we leave such checks to the compiler. In this post I would like to give a short overview and explain how to use a strict type system for everyday checks instead of writing type checks, tests and documentation for it.

How to effectively visualize an Application Landscape in Enterprise Architecture

How to effectively visualize an Application Landscape in Enterprise Architecture

In enterprise & solution architecture, connecting boxes with arrows is an often used and overrated visualization from high-level, thru component architecture, down to data and class diagrams. However, to create a holistic view on systems, component diagrams are not enough! When it comes to analysis or transformation of a high-level application- or service-architecture, I prefer to draw an Application Landscape Diagram, which I would like to show and elaborate on in this post.

Securing isolated systems: Caveats of using plain OAUTH flows and how to solve them

Securing isolated systems: Caveats of using plain OAUTH flows and how to solve them

While OIDC and OAUTH are well-known standards, they don’t fit every purpose “out of the box.” In businesses with special regulations like banking, health care, etc., non-functional requirements to auth can be challenging. Different solutions and ways were evaluated to create a new identity provider for a medical network. The first approach was “just” using simple OAUTH by its most famous Authorization Code Flow. Of course, it failed fast, and I’ll show why and how we solved it in this post.

Online Courses for Developers - A slightly more Critical View

Online Courses for Developers - A slightly more Critical View

We have a massive skills shortage in IT, especially in development. A natural effect of this is that there are many career changers and, as a result, alternative educational opportunities. These alternatives, mostly YouTube video courses and other online offerings, are good knowledge brokers but have downsides. Especially in such a knowledge-driven environment, scientific methods are more important than entertaining course design.
