We discuss the main concepts behind event-driven programming, which, after object-oriented programming, is another fundamental stepping stone in understanding modern embedded software.

In this article, I discuss asynchronous event-driven programming and how it's done in Twisted. Because reading about code only gets you so far, I cite examples from a real Twisted application ...

That’s why P, or an equivalent safe asynchronous event-driven programming language, is essential and should be a required tool in every IoT or microservices developer’s toolkit.
