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.

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.

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++.
Creating an architecture means answering many questions about the ecosystem, in which the Qt embedded system operates. While the questions are very similar for all Qt embedded systems, the answers and their priorities differ. So, you should be able to transfer the questions and answers from my running example, a harvester terminal, to your system.

Our quest for a successful architecture of a harvester terminal continues. In this episode, we discuss when a system with a single application is good enough and when a system with multiple applications and a window manager is the better choice. Sometimes, a single-application system with a window manager is just the right choice.
