HaskellerZ Meetup Group

Main HaskellerZ meetup page.

This repository mainly hosts the slides from past meetups. The README moreover serves as a drafting document for upcoming meetups.

In general, we'll have a HaskellerZ meetup every last thursday of January until October every year. Note that we welcome guests and will happily adjust our schedule if they would like to give a talk.

Suggested topics for upcoming meetups

This is a list of meetup topics suggested by HaskellerZ members. If you would like to give a talk about one of these topics or suggest a different one please message the organizers (preferably Martin O.) on HaskellerZ meetup page.

  • Type Level Programming (Phantom Types)
  • Yesod Framework
  • Software Transactional Memory (runtime characteristics)
  • Dependent Types for Haskell
  • Functional data types (abstractions) vs imperative data types (abstractions)
  • Ways of modeling side effects (I/O) in programming languages
  • Recent advances in parsing libraries in Haskell
  • Conduit, Pipes, IOStreams and similar streaming libraries
