The Quiplash Showdown: Go vs Scala
summary
A Quiplash clone called justcloud gets built in both Go and Scala and the comparison drills into actual choices: Go uses goroutines, channels and mutexes to implement a run Loop per game, Scala uses actors (Peco/Petco/PCO in the transcript) and immutable case classes; both scale to hundreds of thousands of lightweight threads/actors. Timeouts are implemented with goroutine sleeps vs futures + pipeToSelf, responses use ask/! operators. The Scala actor version is preferred for simpler state/timeouts; both implementations run.
