Installing Linux Images on Toradex Verdin Boards
In the post Setting Up Yocto Projects with kas, we built the Linux image for the Toradex Verdin iMX8M Plus. It's time to flash the image on the board using the Toradex Easy Installer (TEZI). It's
Parking at Munich Airport: An Awful Experience
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
Can We Use Trunk-Based Development for Legacy Software?
Not right away! Trunk-Based Development requires that the software builds and passes enough tests, before we integrate our changes into the main branch (a.k.a., trunk). We have enough tests, if breaking the software is highly unlikely. By
Applying TDD to Classes Accessing Files
We start with unit tests reading a file line by line with QFile. Unit tests accessing the file system are not considered unit tests, as they may be slow and may depend on each other in surprising ways (see A
Implementing Qt Signals and Slots in Pure C++
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
Applying TDD to HAL Drivers with Memory-Mapped I/O
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-
Visualising the Architecture of Qt Embedded Systems: Context and Container Diagrams
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
Setting Up Yocto Projects with kas
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.
A Basic Continuous Integration Pipeline with GitHub Actions
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
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
Reading: The five keys to a successful Google team
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.
