7.20 pm: Second talk- Chris Birchall, @cbirchall -Principal Software Developer at OVO Energy


Massaging case classes with shapeless


Shapeless is a powerful tool for reducing boilerplate in your Scala code, but it can be intimidating at first. I'll give a gentle introduction to some of shapeless's most fundamental tools for generic programming, including HList, Generic and LabelledGeneric, and show how you can use them to concisely convert your data from one case class representation to another. I'll also give a taste of some more advanced techniques for "massaging" data, which can be necessary when the input and output representations don't match exactly.


7.40 pm: Third talk- Jamie Pullar, @JamiePullar – Architect at Concentra Analytics


Cats MTL in action


At Concentra we have used abstract MTL patterns in our production service architecture for a number of years now.  We are currently migrating across to the cats.mtl library which brings with it a heightened level of abstraction and composability whilst removing a lot of previously required boiler plate.  In this talk I will give a brief overview of how to use cats mtl. Extol the benefits of implementing such an architecture. Share some of the more interesting consequences, as well as how we have resolved various challenges along the way.


8.00 pm: Craft beer, Pizza & laughter


9 pm+: Finish up at the local pub


Please RSVP as soon as possible as we have limited spaces available, we look forward to seeing you all on Wednesday 23rd of May.
