Haskell: A Practical Introduction

Together with the System Programming Ghent group, we are organizing an intro to Haskell. We'll try a more practical approach, starting with a two simple practical problem and solving them using Haskell (a lazy and expressive functional programming language):
1. A (very!) basic ray tracer
2. A simple web service
Through these examples, we will be learning the fundamentals of Haskell, including concepts like pure functions, monads for side effects, and algebraic data types.
