Josh Suereth discusses Scala: expressions, abstracting behaviors, FP & OOP, Futures & Promises, libraries with implicit classes and value classes, tracking lexical state with implicit values.
Adam Warski shows how to replace features of DI containers with plain Scala code using MacWire, and adding interceptors using macros.
Marc-Daniel Ortega shares code snippets showing how to implement some logic in a functional language inspired by “Functional Programming in Scala”, avoiding the OOP influence.
Stefan Chis demoes building a Lisp dialect in Scala, covering: parsing code, defining data types and functions, evaluating expressions, implementing higher order functions.
Adam Rosien introduces scalaz, how to use it to make code simpler and type safer, how it compensates for Scala issues, and how it encapsulates DI and data validation.
Olivier Chafik discusses how to make a practical use of reified trees in Scala, with two applications: run-time (re)compilation for extreme speed, and conversion to another language (OpenCL).
Sadek Drobi introduces the Play Framework for developers interested in doing web programming in a functional language.
Trisha Gee demoes building a web application using Java, HTML5, Angular.js, Mongo.DB, Groovy and microservices in one hour.
Age Mooij shares some tips&tricks for the Scala developer: type aliases, type and class tag, auto-lifted partial functions, nostacktrace, type classes, context bounds, low priority default implicits.
Deepak Giridharagopal discusses "immutable infrastructure", PuppetDB and complex invariants, PuppetDB’s architecture, the experience of bringing Clojure to a Ruby shop and lessons learned from that.
Jamie Allen reviews some of the actor patterns as implemented in Akka and Scala.
Jamie Allen describes three patterns using Akka actors: handling a lack of guaranteed delivery, distributing tasks to worker actors and implementing distributed workers in an Akka cluster.
