We’ll start at 17:30 with mingle. The meeting starts at 17:45. We’ll have a short break around 18:30 for food and drink.
The Door to Real-World Functional Programming
The monad design pattern is used heavily in functional languages to model side effects in what is otherwise a side effect free programming environment. The pattern can often represent a hurdle to developers learning functional programming, as it is rarely encountered in other traditional paradigms such as object orientation. But understanding monads, and being able to utilize that pattern effectively, is essential for anyone who wants to take their functional programming skills beyond the ability to solve simple toy examples.
This presentation aims to illustrate what monads are, and how the concept of monads is used in Haskell to construct programs where state and side effects are both necessary and desirable. It will do so by focusing on a set of case studies where monads provide a convenient design pattern for modeling sequences of operations.
The presentation assumes a basic understanding of Haskell and its syntax. Attendees who are unfamiliar with this language might benefit from watching the presentation "Functional Programming for the Object Oriented".
Øystein Kolsrud is a C# developer at Qlik in Lund, but has extensive experience of using both C++ and Haskell for real world applications. He holds a Master of Science degree in Computer Science and Engineering from Chalmers University of Technology and has a strong interest in computer languages in general and functional languages in particular.
