Well, I’m running out of anti-patterns and oddly looking code from the legacy of my job-ancestors. I thinks that there are a few that are worth mentioning but don’t build up to a stand-alone post, and then its space for questions and discussions and whether exists or not a way out.Continue reading “Our Father’s Faults – Wrapping it up”
Out Fathers’ Faults – Actors and Concurrency
When I started this job and faced the joyful world of Scala and Akka I remember I was told that thanks to the Actor model you don’t have to worry about concurrency, since every issue was handled by the acting magic.
Some months later we discovered, to our dismay that this wasn’t true. Or better, it was true most of the time if you behave properly, but there are notable exceptions.Continue reading “Out Fathers’ Faults – Actors and Concurrency”
Our Fathers’ Faults – Actors – Explicit State
This post is not really specific to Scala/Akka, since I’ve seen Finite-State Machine (AKA FSM – not this FSM) abuse in every code base regardless of the language. I’ll try to stick with the specificities of my code base, but considerations and thoughts are quite general.
FSM is an elegant and concise formal construct that helps in designing and encoding and understanding simple computational agents.Continue reading “Our Fathers’ Faults – Actors – Explicit State”
