In the ever-evolving landscape of software development, maintaining high-quality and reliable software is paramount. To achieve this, rigorous testing practices and robust development methodologies are essential. This article delves into various testing strategies and tools specific to C++, emphasizing the importance of automated regression tests, test coverage, compiler warnings, code formatting, static code analysis, sanitizers, and continuous integration (CI). By adopting these practices, teams can ensure their software remains reliable, maintainable, and bug-free.

In this article, I share my initial impressions gathered from my first steps with Torizon, a Linux-based containerized embedded OS developed by Toradex. Torizon aims to simplify the user experience and customization process compared to alternatives like Yocto. It achieves this by running user applications within custom containers on a base OS, supported by an array of tools. While Torizon simplifies the setup and lowers the entry barrier for newcomers, I found it occasionally challenging as an experienced Embedded Linux and Yocto user.

Embedded Software Meetup Zürich ist zurück! Nach längerer Pause des "Embedded GNU/Linux Developer Meetup" führen wir es als "Embedded Software Meetup" wieder durch. Es geht um: Embedded Software Entwicklung Embedded Linux Zephyr Qualität Software Craftsmanship und vieles mehr. Im Fokus steht der Austausch zwischen Entwicklern und anderen gleichgesinnten. Den Anfang macht Urs Fässler mit seinem Erfahrungsbericht zu moderner Applikationsentwicklung für Embedded Linux.

Clean Code und Software Craftsmanship helfen, Embedded Systeme sicher zu machen (safety und security). Diese Botschaft hat uns Simon Künzli im aktuellen Kurs Security in Embedded Systems an der ZHAW School of Engineering vermittelt, und ich stimme absolut zu. Es sind Methoden, Prinzipen und Praktiken welche ich seit bereits 10 Jahren anwende und sehr zu schätzen gelernt habe. Vielleicht tönt TDD, BDD, CI/CD, Review und was es alles gibt abschreckend.

Public Money? Public Code! Wie have it in Switzerland. See the talk from Matthias Stürmer at OpenSource at Siemens how he did it.

Very happy to announce that I founded my own company: The go to place when you need - Quality Software - Embedded Linux Software and Systems - Open Source Specialists - Software Architecture - Shorter delivery and feedback cycles and any combination of it.

Investigating Yocto issues can be challenging. Yocto employs Bitbake, which heavily relies on variables (lists) that are set, appended, prepended, and modified across several recipes. Other recipes reference these variables to make decisions and modify additional variables. One particularly troublesome variable is DISTRO_FEATURES. Numerous recipes manipulate this variable, and any change typically triggers a rebuild of most packages. In our case a colleague was missing systemd within DISTRO_FEATURES, although it was present in my configuration.
