Parking at Munich Airport: An Awful Experience

by Burkhard Stubert
2022/10/24

The parking experience at Munich Airport is awful. It is too easy to do something wrong, which can only be remedied by calling support. The bad user experience is caused by a bad system architecture. The pieces for a better architecture are already in place. Improving the interaction between these pieces improves the architecture and a fortiori the user experience. I can at least dream of a better parking experience in the future, although I can’t change the current one.

Signals and slots are my favourite Qt feature, as they make loose coupling between components or between layers super easy. I miss them most when I must write pure C++ code without the Qt goodies. I invite you to follow along while I translate signals and slots into function-object member variables and lambda functions, respectively.

I never got the hang of UML: overly complicated, hard to understand, too close to code. Hence, I was skeptical about C4 diagrams when I… Read More »Visualising the Architecture of Qt Embedded Systems: Context and Container Diagrams

Visualising Module Dependencies with CMake and Graphviz

CMake uses Graphviz to generate dependency graphs between the targets of a CMake project like libraries and executables. The graphs help us get an idea of the software architecture and identify the dependency hot spots.

I gave a talk at Meeting Embedded 2021 on 4 November 2021. First, I introduced the hexagonal architecture (a.k.a. ports-and-adapters architecture) in general. Then, I showed a walking skeleton of the architecture for a harvester terminal.

Creating an architecture means answering many questions about the ecosystem, in which the Qt embedded system operates. While the questions are very similar for all Qt embedded systems, the answers and their priorities differ. So, you should be able to transfer the questions and answers from my running example, a harvester terminal, to your system.
