  • Why building web-apps in Haskell is harder than it ought to be

    I was enjoying writing Haskell till the time I was dealing with JSONs and talking to the Telegram API. But as soon as I wanted to deal with the database, write HTML templates, or process forms, I was hitting a lot of friction.

  • OverloadedLabels Considered Awesome

  • Bitrot-free Scripts

    There are good reasons why people like to use scripting languages. This blog post is going to demonstrate doing some non-trivial work with Haskell, and do so with a fully reproducible and trivially installed toolchain, supported on multiple operating systems.

  • Foundation: an alternative prelude with batteries and no dependencies

    This package has the following goals: provide a better and more efficient prelude than base’s prelude.
