Featured

  • Composite 0.6 Released by Dan Fithian

  • Demystifying MonadBaseControl by Alexis King

  • Remote Interactive Courses by Christine Gundry and Andres Löh

    Given the success of introducing an online version of our “Type level programming with GHC” course, we’re offering this again alongside two of our other courses: “Compact Introduction to Haskell” and “Performance and Optimisation”.

    People keep asking me, “What’s the point of Haskell, why do you folks even use it?”. How can you answer this?
