  • Basic Data Scraping in Haskell Part 1: HTTP and JSON by Zac Wood

    In this short series, I will walk you through scraping JSON data from the web using basic libraries, and eventually bringing it into the IHP web framework to be used in an actual application.

  • Compile-Time Evaluation in Haskell by Vladislav Zavialov

    That’s why you are about to see not one, not two, but three ways to do compile-time evaluation in Haskell (there may be more, but let’s not get too esoteric).

  • Elementary programming by Michael Peyton Jones

    So we have a dilemma: abstraction is great for the advanced users, but is inevitably going to make your code hard for less advanced users to understand.

  • A First Look at Info Table Profiling by Matthew Pickering & David Eichmann

    In this post, we are going to use a brand-new (at the time of writing) and still somewhat experimental profiling method in GHC to show how to identify a memory leak and the code causing it.

  • Hacking Haskell in a Scottish castle by Satnam Singh

    At some point I hope to move back to Scotland to start a software company in a castle. We will specialize in using Haskell to write high quality code for discerning customers.

  • Issue #2 by Bind the Gap

    We are delighted to present our second issue of Bind The Gap (BTG), which also happens to be the special festive winter issue!

  • Lessons Learned From A Year Of Writing Haskell by Adam Wespiser

    The majority of my Haskell experience is in the form of writing code for web servers that talk to databases serve up APIs, although I am very interested in compilers and language research!
