Type classes for Java devs & Pragmatic object-oriented tagless final

Talk #1: "Scala type classes for Java refugees" by Rafał Kucab

Abstract

The presentation will cover the basics of a very powerful and flexible concept of type classes which adds ad-hoc polymorphism to Scala language. We will go through a very simple example of how to implement and use this mechanism in your code. If you are learning Scala or you are an experienced Java developer and want to know how it works from scratch this presentation is for you.

Talk #2: "Pragmatic object-oriented tagless final" by Wojtek Pituła

Abstract

Tagless final was born in Haskell world but this doesn’t mean we have to copy it blindly. Can we get some value out of it without abandoning all the libraries and patterns people developed over the years in OOP in general and Java in particular? Let’s add classes, objects, type members and other Scala features to the picture and look at it with pure pragmatism in mind. Will it look the same?

Bio

I solve problems, sometimes with code, if absolutely necessary. In a complicated relationship with Scala for over 4 years. Trying to make laziness an art.
