Featuring Rúnar Bjarnason

Scala is not a purely functional programming language. But we can restrict ourselves to a purely functional subset of Scala. The question is: should we? This talk will make the case that the answer is unequivocally "yes". We can treat Scala as a purely functional language. But more than...

Type-Level Computations in Scala

Featuring Stefan Zeiger

Scala has a powerful type system that allows many properties of a program to be verified at compile-time. Do you still think of types as Int, String and Object? Types like ""Fold[Nat, ({ type L[X <: HList, Z <: Nat] = Succ[Z] })#L, Nat._0]"" are only a small step away....

All you don't need to know about typeclasses

Featuring Julien Sirocchi

Scala syntax is succinct, clean and easy to read, however some of the library signatures that support this are more complicated than one might expect. Type-classes use sophisticated signatures to enable clean client code. This talk is aimed at novice or intermediate Scala developers wanting to...

Developing a distributed application presents many challenges and one of the biggest is integration testing. While we have many tools at our fingertips for tackling unit tests integration tests are run manually within many projects. Most of the time this is because an integration test requires a...

Under the Hood of Scala Implicits

Featuring Alexander Podkhalyuzin

Implicit conversions and implicit parameters are fundamental and unique features of Scala that are powerful at the same time. To use these features to their maximum potential, and do so with confidence, you have to understand the specifics of how Scala compiler’s implicits search works. I will...
