Everybody knows monads by now, so a talk about monads would hardly be worthwhile. Let's take it to the next level: monad transformers. You'll learn what they are, how they naturally emerge in your code base and how to make good use of them in Scala – and maybe even how to create your own.
Programmation en Logique
Prolog is one of the most underrated programming languages around; possibly because of its strange syntax and the unusual paradigm. But it is a very nice special-purpose programming language. In this talk, I introduce Prolog’s programming model, showcase some programming domains in which Prolog allows for very concise, elegant programs, and finally describe how it can also be used as a general-purpose tool.
Numeric Programming with Spire
Numeric programming is a notoriously difficult topic. For number crunching, e.g. solving systems of linear equations, we need raw performance. However, using floating-point numbers may lead to inaccurate results. On top of that, as functional programmers, we’d really like to abstract over concrete number types, which is where abstract algebra comes into play. This interplay between abstract and concrete, and the fact that everything needs to run on finite hardware, is what makes good library support necessary for writing fast & correct programs. Spire is such a library in the Typelevel Scala ecosystem. This talk is an introduction to Spire, showcasing the ‘number tower’, real-ish numbers and how to obey the law.
