The post Guide to the Total Cost of Ownership of Open-Source Software by Peter Schneider (The Qt Company) provides a smorgasbord of alternative facts why we should not use Qt LGPL but instead buy Qt Commercial. I can’t miss the irony that Schneider like many of his sales colleagues are bad-mouthing Qt LGPL to promote Qt Commercial. Qt LGPL and Commercial share the same code.

Building a CI Pipeline with CTest and CDash

We can use CMake, CTest and CDash to build a basic Continuous Integration (CI) pipeline. The pipeline builds the applications, runs the tests, collects coverage information and uploads all the results to a dashboard on a web server. All this is controlled by one CMake script executed by CTest.

In her post The five keys to a successful Google team, Julia Rozovsky summarises the recipe for successful teams: “Who is on a team matters less than how the team members interact, structure their work, and view their contributions.” Here is my commentary.

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?

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.

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.
