Overview

The world's most vibrant Haskell conference is back for an 11th great year!

Connect with hundreds of like-minded Haskell enthusiasts as we explore what's new and what's next in Haskell.

We're thrilled to once again welcome the global Haskell community to join the Haskell eXchange conference via our virtual conference platform, where across 2 jam-packed days, you'll discuss new technologies, meet future collaborators, and learn new skills through practical, coding-based sessions.

Or, if you're keen to get some face time with fellow Haskellers, why not make the trip to CodeNode in London, England, where you'll learn side-by-side with hundreds of other Haskell developers at our in-person conference

Plus, back by popular demand, our “Novice Track”day will offer a bonus day of beginner-friendly talks exclusively for online attendees.

Simon Peyton Jones delivers a keynote session at previous Haskell eXchange conference.

What is Haskell eXchange?

Haskell is an advanced, purely functional programming language. What began as a research language has evolved into a unique, cutting edge language that is used in industries as diverse as Aerospace, Automotive, Healthcare, Finance, Education, Retail, Logistics, SaaS, Online Retail, TV and Music.

Haskell eXchange is a community-focused conference for Haskell enthusiasts. At Haskell eXchange all of the content is selected by developersfor developers.

Past keynotes have included Simon Peyton Jones, Gabriele Keller, Niki Vazou, Stephanie Weirich, Sukant Hajra, Simon Marlow, and Gabriel Gonzalez. We'll be announcing this year's VIP keynotes a little closer to the event, so stay tuned! If you'd like to be among the first to hear about updates, register here.

Programme

How We Haskell: Enterprise Edition

Haskell is used in the enterprise, but the story hardly stops there. The language and ecosystem present many options, what choices are being made to facilitate mainstream development? What are the pain points? What tools are used? Do enterprise organizations expect things that are missing? How is the language itself used? Here we journey through the maze of choices with the language and the ecosystem, explore concrete choices that have been beneficial, and more.

This session follows up on last year's, Haskell in the Enterprise: A Report from in the Belly of the Whale, offering new lessons for teams using Haskell in the enterprise.

Gabriella Gonzalez on "Grace"

We are excited to welcome Gabriella Gonzalez to Haskell eXchange!

Gabriella joins us to discuss her new "Grace browser" project, which can dynamically convert a wide variety of functional programming expressions to their equivalent HTML.

Stay tuned for more details on the talk, to be announced very soon!



Gabriella Gonzalez

Gabriella is a functional programming evangelist best known for her blog, Haskell for all (haskellforall.com), and also for authoring the Dhall configuration language (dhall-lang.org). She not only promotes functional programming languages, but also draws inspiration from them to rethink and simplify imperative programming architectures. When she's not contributing to open source (@Gabriella439) she frivols away her time on Twitter (@GabriellaG439).


Just Because It Works Doesn't Mean It's Right: Finding Elegance in Quadtrees

Quadtrees are well-known containers for spatial data, but little attention has been given to them in a functional setting. In this talk we will explore the design space of quadtrees and find reusable techniques to discover elegance, in both their design and implementation.



Sandy Maguire

Sandy is an independent researcher, who spends his time dabbling in Haskell. He is the author of Thinking with Types, Algebra Driven Design, the polysemy library, and the Wingman extension for the Haskell Language Server. By day, he likes strumming guitars.


Glean: Data About Code

What if accurate semantic information about your code was available through a rich query language that produced results in milliseconds? And what if that worked at scale, so that you had information not just about the files you're working on, but the entire stack in which your code lives? You could use that to build IDE integration, code search and browsing tools, code analysis tools, as well as any ad-hoc tooling or infrastructure that needs accurate semantic information about code.

At Meta we're building Glean, an open-source system for storing and querying information about code at scale. Glean is implemented mostly in Haskell, using the open-source RocksDB engine for storage. Glean comes with indexers for several languages.

In this talk I'll take a tour through what Glean can offer, with a particular focus on how Haskell has enabled some rather nifty features that make working with Glean safer and more efficient.

Keynote by Simon Peyton Jones

We are honoured to welcome back Simon Peyton Jones to the Haskell eXchange. Since the very first Haskell eXchange in 2012, we've been lucky to have Simon join us each year to share his unique perspective on our favourite programming language. Over the years he's helped us explore everything from front end features to join points , Linear Types, and pattern matching — all the way to last year's keynote, Provably correct, asymptotically efficient, higher-order reverse-mode automatic differentiation.

This year Simon will join us with a brand new technical talk. Details will be announced closer to the conference. Stay tuned! Check out all of Simon's previous Haskell eXchange talks here.



Simon Peyton Jones

Simon Peyton Jones, MA, MBCS, CEng, graduated from Trinity College Cambridge in 1980. Simon was a key contributor to the design of the now-standard functional language Haskell, and is the lead designer of the widely-used Glasgow Haskell Compiler (GHC). He has written two textbooks about the implementation of functional languages.

After 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.


Haskell Cat: A Command Line Tool Workshop

One of the hardest things about learning Haskell is figuring out how all the pieces fit together. Maybe you've learned a bit about lazy lists and magnificent monads, but it's hard to know how to put those ideas together to make a real program.

In this workshop-style talk, you'll learn how to put the pieces together and build a working command line application from scratch. During the talk you'll see how to design and refactor the architecture of a Haskell application, how to set up a new project with cabal, learn how to design functional data structures like zipper lists, and get hands-on experience with common patterns like monad transformers. This talk is appropriate for beginner and intermediate Haskellers. You can enjoy the talk on its own, or use it as a companion piece to chapters 8, 9, and 13 of Effective Haskell.

This session will be part of our free Haskell eXchange: Novice Track on 7 December 2021. If you've heard of Haskell or Functional Programming but aren't sure where to start, our new free "Novice Track" day is the perfect no-pressure way to learn about Haskell.



Rebecca Skinner

Rebecca Skinner is a software engineer with over 10 years of experience in Haskell and functional programming across industries including fintech, security, cloud infrastructure, and data science. She's a lead software developer at Mercury, and the author of the book Effective Haskell.


Clash: Haskell for FPGA Design: It's easy as 1-2-3...419,200

FPGAs can bring the versatility of custom chip design to the desktop of the hobbyist. But what does it look like to actually make something fun out of an FPGA, and how can Haskell help with that?

In this talk, we'll find out what an FPGA even is, and then learn just enough Clash to build, in full detail, a fully functioning Flappy Bird circuit. Turns out, all we need to do is count to 419,200 and the rest just follows!



Gergő Érdi

Gergő Érdi has extended GHC by adding pattern synonyms, used SMT solvers to analyze old text adventure games, and programmed AVR microcontrollers in Rust before it was cool. Lately, his chaotic interest turned to Clash, the Haskell to FPGA compiler. This led to him writing two things: the "Retrocomputing with Clash" book, and self-introductions in the third person.


Get Involved

Would you like to speak at Haskell eXchange? We want to hear your proposals!

Speaking at a conference is a powerful way to share your ideas and influence where your favourite technologies are headed. As a speaker, you will have the opportunity to share your knowledge and experience with a global audience of practitioners. We recommend that you explore the programs from previous editions of Haskell eXchange before submitting a talk proposal. Every conference is unique, and developing an understanding of our audience and previous sessions will provide your talk with the best chances of being selected.

At Haskell eXchange we're looking for talks and workshops on all things from the world of Haskell and GHC, but also topics that brush up against that world, including other programming languages, architecture, security and more.

New this year! We are looking to hear your proposals for Half-Day and Full-day Haskell workshops.

This year we are we are actively encouraging submissions on the following topics:

  • Haskell libraries and language extensions
  • Software testing
  • Tooling and tool suites
  • Security
  • Concurrency in distributed systems
  • Integration of Haskell on the browser
  • What can Haskell learn from other languages (e.g.Scala, Racket, Rust)
  • How to make the transition from learning to real-world Haskell
  • Adoption stories and real-world applications of Haskell
  • Haskell and Hardware (e.g. Bluespec, ImplicitCAD, Clash)
  • Optimization and Performance
  • Running productive Haskell teams in industry
  • Data and Machine Learning
  • Applications built using Haskell
  • Mentoring/Community
  • This year we are especially looking for introductory talks on Advanced Haskell topics. So even if you don't have something burning hot to share, you've probably got some knowledge to share about a more intermediate topic.

Diversity Matters Scholarship

Is it rare that you see someone at tech conferences that reminds you of yourself? Then you’re probably underrepresented at tech conferences.

At Skills Matter we are committed to supporting diversity in speakers, conference participants, and the wider technology community regardless of regardless of ability, ethnicity, gender, sexual orientation, religious views (or lack thereof) and socio-economic status.

To increase diversity at Skills Matter events we offer scholarships to people from underrepresented groups in tech who wouldn’t otherwise be able to attend.

If you believe you are a member of a group that is underrepresented within the tech community or at technical conferences we encourage you to apply.
