Haskell eXchange 2015
Topics covered at #haskellxFeaturing two days of talks, demos and discussions, the Haskell eXchange is an opportunity for Haskellers to meet, talk, learn, share skills and exchange ideas. Everyone is welcome to join, whether an expert or a beginner, whether commercial user, academic or hobbyist.
Line Up 2015
View this year's speakers, topics and workshops/tutorials here.
The Haskell eXchange is an independent conference organised for and by the community. We are therefore looking forward to these year's talks and workshops in particular on:
- Talks about Haskell libraries and tools
- Experience reports on the use of Haskell in various environments
- Tutorials on the use of Haskell itself, or particular Haskell libraries and tools
- Coding techniques, tips and tricks
- Talks about the implementation of Haskell compilers and tools
- Ideas for language design and the future of Haskell
- Impressions of other programming languages that are related to Haskell
There will be three types of session:
- 45 minute talks
- 15 minute lightning talks
- 2+ hour hands on sessions / tutorials
Haskell Infrastructure Hackathon
There will be a Haskell Hackathon following the conference. Find out more here.

Lastly, even if you want to do none of these things, I think you may enjoy the adventure. Core is a tiny but super-expressive language that can express all of Haskell, including all the types, and more beside. It pulls off this trick by drawing directly on System F, a mathematical calculus from type theory. Functional programming is amazing: serious theory leads directly to beautiful implementations.

About the speaker...
Simon Peyton JonesAfter two years in industry, he spent seven years as a lecturer at University College London, and nine years as a professor at Glasgow University before moving to Microsoft Research (Cambridge) in 1998. His main research interest is in functional programming languages, their implementation, and their application. He has led a succession of research projects focused around the design and implementation of production-quality functional-language systems for both uniprocessors and parallel machines. More generally, he is interested in language design, rich type systems, software component architectures, compiler technology, code generation, runtime systems, virtual machines, and garbage collection. He is particularly motivated by direct use of principled theory to practical language design and implementation -- that's one reason he loves functional programming so much. |

The story covers: - picking a dynamically-typed functional language, suffering from it and recovering; - surviving in a cruel stringly-typed world of Unix; - implementing system software in Haskell and operating it; - overcoming challenges of Haskell deployment; - using Haskell to integrate with various 3rd-party services; - successfully abandoning traditional DevOps tooling that plagues the industry.

There have been multiple attempts at proving that Haskell can be used to write games, but none have been definitive enough to convince those outside the community. Keera Studios was founded as a way to turn this situation around, by creating more and more complex games and demonstrate, by example, the possibilities and benefits of functional programming. To prove that Haskell is a suitable choice for game programming, we want to do real multimedia and interact with real modern hardware, target (at least some) gaming platforms; and show that FP principles and techniques are beneficial for game development. Our work in game programming has demonstrated that Haskell is a worthy contestant. We have created games that interact with Kinect, Wiimotes and Leapmotion, use OpenGL and SDL2 (SDL is used in games such as Angry Birds) for multimedia, target mobile platforms such as Android and are available for purchase on Google Play. We have also explored different ways to take advantage of pure functional programming, either by means of an embedded DSL (like in our Cross-platform Graphical Adventure Game Engine GALE) or using FRP (Keera Magic Cookies, Keera Breakout), and also for game testing and profiling purposes. In this workshop I will demonstrate, by example, how to write games that combine these features, what to watch for, where the current challenges lie, and how we can, as a community, use the creative and fun process of game programming to bring Haskell to the world and vice versa. Whoever wants to follow the talk with their own laptops should be able to compile this haskell package: https://github.com/keera-studios/haskell-game-programming There's no need to read/process the material ahead. If it compiles, they are good to go. It usually takes just 2-7 minutes on my machine, so if they can't get it working before the talk, that's ok. I strongly recommend using a sandbox. |

About the speaker...
Oliver CharlesFast forward to 2014, and Oliver is perhaps best known for his yearly 24 Days of Hackage series of blog posts, where he spends 24 days at the end of the year blogging about different Haskell libraries. Whether it's game programming, database querying, type safety, or high performant data processing - there's probably a library about it that he's blogged about! Oliver is currently the author of a collection of Haskell libraries, a developer for CircuitHub.com, and an active speaker with the London Haskell User Group. |

Since Docker is a fairly new technology, there is still room for exploration to find the best way to set up development environments. In this talk I will give a short introduction to Docker and I will show how I set up my development environment using Docker containers. The main benefits of this setup will be portability across dev machines and isolating the development environment. To underline these benefits, I will demonstrate how I created and deployed a chat bot using Haskell. Join us at the Haskell eXchange in 2016!Want to learn about the latest innovations in Haskell?

About the speaker...
Neil MitchellNeil is a strong believer in the functional approach, finding the combination of conciseness, static-typing and testability to offer significant advantages. He is currently developing a number of open source Haskell projects, all of which can be found on his Github page or on Hackage. He welcomes both contributions via pull requests and bug reports via the GitHub issue trackers. Some of my more popular projects include:
