Oskar Wickström

Finite-state machines? Your compiler wants in!

When modeling problem domains, we collect different possible states, legal transitions between states, and relevant data for each state. Finite-state machines emerge. To verify that programs are constructed correctly, and to have a living machine-verified documentation, we should let the compiler in on our trade secrets.

In this talk we will look at motivations and examples of encoding finite-state machines, using the expressive type systems of Haskell and PureScript. We will see how they help us in implementing our model, and how they communicate a high-level design.

Oskar Wickström

After some years of musical education, Oskar Wickström began his journey into the world of software. He’s currently doing remote work in Haskell. Among the technical topics that interest Oskar are functional programming, systems design, web technology, and programming languages. His more aesthetic side, which mostly involves music, draws him towards graphics and UI design every now and then.
