With Team Topologies, Matthew Skelton and Manuel Pais have written a brilliant book how to create a high-performance software development organisation with the best team structure and interaction. Organisations are complex adaptive systems that change as the result of the interactions between their components (e.g., the teams) and the interactions with other systems (e.g., the rest of the organisation, competitors, suppliers, technology and market trends). The resulting changes are hard to predict and hard to control.

Building Qt 6.2 For Old Yocto Versions

The Qt version of an embedded Linux system is tied to the Yocto version. Yocto 2.7 (Warrior) comes with Qt 5.12, Yocto 3.1 (Dunfell) with Qt 5.14, Yocto 3.2, 3.3 and 3.4 with Qt 5.15 . There is no Yocto version with Qt 6 yet. How can we build Qt 6.2 against the SDK of old Yocto versions?

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.

Book Review: “The Art of Readable Code” by Dustin Boswell and Trevor Foucher

When I looked up the publishing date for this book, I was surprised to find out that the book is 11 years old. The content feels as if written today. The authors’ advice is as relevant as ever. I am sure that it will stay relevant at least for the next 10 years.

Almost all companies I worked with over the last 25 years had an oversupply of non-technical managers and an undersupply of technical experts in leadership positions. These companies build products with less value for the users and take longer to do so. Apple shows that companies can succeed with a functional organisation, where experts lead experts.

Although Qt comes with a unit-test framework QuickTest for QML code, hardly any QML GUIs are unit-tested, let alone developed with TDD (test-driven development). One… Read More »Developing a QML Keypad with TDD

My Talk “Hexagonal Architecture: The Standard for Qt Embedded Applications” at Meeting Embedded 2021

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.

It depends! If a C++ source file includes the header inside an extern "C" section, the header is compiled as C++. If a C source file includes the header, the header is compiled as C. Hence, the header file should be both valid C and valid C++.
