Haskell eXchange 2021

The 2021 Haskell eXchange will be an online conference hosted on the Hopin platform.

At Skills Matter, we’ve chosen to see the events of the past year as a challenge to make our content and community more inclusive and accessible to all. Beyond the COVID‑19 pandemic, we have a vision of a community where knowledge sharing and skills transfer are not limited by physical barriers.

By hosting Haskell eXchange online in 2020, we were able to truly welcome a global community of Haskell enthusiasts and developers to the conference.

We are excited to be able to offer this opportunity again for 2021 and hope you can join us!

Get Involved

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

The Haskell eXchange Call for Papers is now open! At Haskell eXchange, sessions can take the form of a talk, a case study, a code-focused demo, or a panel.

We actively encourage submissions on the following topics:
  • Optimization and Performance
  • Haskell Libraries and language extensions
  • Tooling and tool suites
  • Adoption stories and real-world applications of Haskell
  • Mentoring/Community
  • Security
  • Data and Machine Learning
  • Applications built using Haskell
  • Integration of Haskell on the browser
  • Case Studies
Submit a Talk

Are you new to Haskell? You've got a unique point‑of‑view and we want to hear it.

New voices will strengthen the Haskell community and help it grow. We strongly encourage new users and first-time speakers to submit a proposal and are very excited to read proposals featuring your fresh perspective.

Submissions should be for one of the following session types (time for Q&A is included in the session lengths):

  • 45 minute talk
  • 15 minute lightning talk
Proposals must be submitted to Skills Matter by 23:59 UTC on 26 September 2021 in order to be considered by the conference’s programme committee. As this is a virtual event, priority consideration will be given to presentations that promise a socially-interactive format. Case studies are also encouraged, particularly case studies where learnings were gained from failure.

If you have an idea for an interactive format, but have technical concerns, questions or would like guidance, please contact us at conferences@skillsmatter.com. We'll be happy to offer technical support.

Talks will be selected by Skills Matter and the Haskell eXchange Programme Committee on the basis of making the conference a varied and valuable event. Submission is open to anyone. First time speakers and speakers from traditionally under-represented communities are especially encouraged to apply.

Chosen speakers will receive two free tickets to the conference: one for the speaker and one for a guest of their choosing.

Please familiarise yourself with our Code of Conduct before submitting. You can find it here.
