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
A client recently asked me to help them get a legacy HAL driver under test. They want to use TDD to maintain and extend the driver. We ran into a couple of problems, because the tests run on a 64-bit
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 first heard about them. When I saw Simon Brown using them in his talk Modular
Kas makes Yocto builds simple. Based on a YAML configuration file, kas starts a container, clones the layer repositories, initialises the conf files and starts building. Each Yocto version builds only on specific host Linux versions. The kas container frees Yocto builds from this restriction.
In a previous post, I built a basic CI pipeline with CTest that uploaded its results to a CDash board. It worked fine except that we had to start the pipeline manually from the command line. In this post, we
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
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.
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
Welcome to Episode 28 of My Newsletter on Qt Embedded Systems This will be the last episode of my newsletter. From now on, I'll do all my writing on my blog. So, you won't have to
Welcome to Episode 27 of My Newsletter on Qt Embedded Systems The war is back in Europe! In a criminal act, Russia is attacking and invading Ukraine - for the second time in 8 years. My heart goes out to
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. Generating Dependency Graphs My running
I am using TDD to implement a hardware-independent mock QCanBusDevice. We can use MockCanBusDevice in unit, integration and acceptance tests - without access to a hardware CAN bus. A terminal application can also use it in its own process to
