In the days when processing power was expensive, writing assembler code was the benchmark, and high level languages were seen as an extravagance, C was a revelation. Near-assembler fast, bit-level operations, but still an expressive 3GL.
Wait, that’s only the beginning of the story.
Event-driven programming, Finite State Machines and NodeJS
I started out in my software engineering life writing software for embedded real-time systems and communication stacks, so I often think of myself as an async native. I’ve written a lot of code in various languages, mostly not using event-driven programming models and design patterns, but hardware interrupts, callback functions, event loops and finite state machines – I still see these as reassuringly familiar features of my original habitat. Call it the baby duck syndrome.
