● Play 2 is rewritten in Scala from scratch
● Uses Netty and Akka behind the scenes
● Java and Scala API

5. Spark
● Started by Matei Zaharia during his PhD work
● Maintained by Apache Foundation
● Written in Scala and actively uses Scala REPL
● Usually much faster than Hadoop
● Enables machine learning and ad-hoc data analysis
● Hosts other projects such as Spark Streaming and Spark SQL
● Java, Scala and Python API

6. Web frameworks
● Play 2
● akka-http (Spray)
● Scalatra
● http4s
● Finagle
● Colossus
● Lift

7. Dependency injection
● Scaldi (Oleg Ilyenko)
● MacWire (Adam Warski)
● Google Guice
● SubCut (Dick Wall)
● Cake pattern

8. Database access
● ScalikeJDBC
● Slick
● doobie (Typelevel)

9. The book
● Suited for people with no prior
experience in Scala
● Includes functional programming tutorial
● Focuses on Play 2.5
