Starting Scala: Between Confusion and For-Comprehension
summary
A beginner-oriented Scala talk that walks from zero to a working backend, focusing on practical technologies: Play2 for routes and controllers, Akka for concurrency, and Slick for database queries. It covers common stumbling blocks (avoiding mutable vars, for-comprehensions needing uniform result types, and having to handle Option/Future explicitly), mentions exercises and ecosystem activity, and presents a playful teaching product called Scala Quest (Kickstarter-funded).
