Introduction This article is the second in a small series of articles that explain how object-oriented programming (OOP) can be applied in C in embedded software projects. In the previous article I explained when and why it makes sense to apply the concept of objects in C, and how to implement them. Doing this makes […]

I’ve finished my woodworker’s workbench to the point where I can use it. Sure, some things are still missing: the IKEA cabinets are still to be placed underneath it and the vice is not installed yet. Nevertheless, now that I have organized my tools around it a bit, the workbench is ready to be used. […]

Last week my colleague Auke Klazema held a short presentation on Test Driven Development (TDD) – you can find it on his website. He already explained me the principles of TDD some weeks earlier, and I was able to implement a small Python module the TDD-way since. My initial experience is that TDD forced me to […]

Every programming language has its own funny, unusual, and good-to-know language constructs. Today, I came to learn two such language constructs in Python. Finding a needle in a haystack Consider the following way to check if a needle exists in a haystack: When run, this will print False, as one would expect, since “Haystack” doesn’t […]
