Many Ways to Concur
45 Mins
Talk
Intermediate
Easy concurrency is one of the main prophesied benefits of the modern functional programming (FP) languages. But the implementation of concurrency differs widely between different FP languages. In this talk, we shall explore the methods and primitives of concurrency across three FP languages: Haskell, Erlang, and Clojure (with core.async).
We shall learn about and compare the trade-offs between
- the green threads and STM channels oriented concurrency of Haskell
- everything-is-a-process and message-passing actor pattern of Erlang
- macro-based CSP transformation of Clojure/core.async

Introduction to Concurrency in Haskell
45 Mins
Demonstration
Intermediate
Haskell is widely known as a functional programming language which is great to write pure (non I/O) code and immutable data structures. But it is not well known that it has a great support for a wide variety of concurrency models too.
In this talk we shall explore the various concurrency models and primitives supported by Haskell including green threads, mutable variables, channels and software transactional memory. We shall see how the purity, laziness, and the strong type system of Haskell come together, and help write clean and modular concurrent code. We shall explore these by writing a mutli-user chat server with support for private and channel chatting.
