C◦mp◦se :: Conference

The practice and craft of functional programming

Compose is a conference for typed functional programmers, focused specifically on Haskell, OCaml, F#, SML, and related technologies.

Typed functional programming has been taken up widely, by industry and hobbyists alike. For many of us it has renewed our belief that code should be beautiful, and that programming can be as enjoyable as it is practical. Compose is about bringing together functional programmers of all levels of skill and experience — from technical leads to novices, and from long-time hackers to students just getting started.

Our experiences have shown that the theoretical can be put into practice with great success, and that topics once considered “advanced” can be made understandable and spread widely. For example, type systems, often considered complex, can simplify our lives by teaching compilers to do some of our reasoning for us.

Compose is about learning together — sharing knowledge, insights, techniques, and sometimes just awesome things we made.
