It’s at the point where it’s ugly but it works, so I’m going to share what I’ve learned so far. Using core.async For Timing And Control In this application, I have two kinds of entities: Timer - This holds a duration and an amount of time that has elapsed. Alarm - This is responsible for providing some kind of effect (like making a sound) when a Timer has finished.

He is able to see things that many of the rest of us cannot, and he is able to analyze and explain his thoughts with a precision that is rare even among programmers. Little did I know that there was a problem with semantic versioning. It seemed like a reasonable system, and I never gave it a second thought until I watched this presentation where Rich exposed what the semantics of this system actually were.
