London Scala Users Group
London Scala Users Group
The London Scala User Group was founded in 2010 and has been organising monthly meetups at Skills Matter since. Come along to some of the meetups to get to know other software developers interested in the Scala programming language, reactive programming and the Typesafe platform. Learn and share skills with the creators of emerging frameworks, tools and libraries like Akka, Spray, Play, Lift, discover how other companies are using Scala or have introduced Scala skills in their engineering teams. Discuss common challenges, adopt skills in coding sessions or simply enjoy conversations with likeminded folks at the post meetup drinks at the Slaughtered Lamb.
You can find and join all our meetups by the London Scala Users' Group (LSUG) community on these pages here.
You can also find recordings (we call them SkillsCasts as they captured film, code and slides) and pictures of past talks & events on these pages.
We hope to see you soon!

An invitation to functional programming
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...

Declarative protocol messages in Scala for testing distributed systems
Featuring Patrick Tschorn
When testing distributed systems, protocol messages have to be parsed, instantiated and modified, which leads to incidental code that obscures the test narrative.

A Field Guide to DSL Design
Featuring Tomer Gabel
Scala combines a powerful type system with a lean but flexible syntax. This combination enables incredible flexibility in library design, most particularly in designing internal DSLs for many common scenarios: specification definition and matching in Specs² and ScalaTest, request routing in Spray...

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...

Using Docker, Scala and Akka for integration tests
Featuring Andreas Gies
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...
