Welcome to another issue of Haskell Weekly! Haskell is a safe, purely functional programming language with a fast, concurrent runtime. This is a weekly summary of what’s going on in its community.


  • GHC 9.2.4 released by Zubin Duggal

    The GHC developers are very happy to at announce the availability of GHC 9.2.4.

  • Diagnose memory leaks on PINNED values with GHC 9.2.1 and up by Ruben Astudillo

    But there was still a thorn on this approach: ByteStrings. On the Haskell heap these are PINNED objects. What this means is that the copying garbage collector gives them special treatment when moving values between the from space to the to space and lets them fixed in place.

  • Kinds and Higher-Kinded Types in Haskell by Gints Dreimanis

    In this article, I will introduce you to the concept of kinds. Then, we’ll use our newfound knowledge to understand what are higher-kinded types and what makes them useful.

  • Magical Haskell by Anton Antich

    Teaching modern typed functional programming and Haskell language in a fun and accessible way using real-world examples and a lot of visuals to help structure abstract concepts and develop intuition.

  • Monad Confusion and the Blurry Line Between Data and Computation by Micah Cantor

    Based on my learning experience, I do have some thoughts on why people seem to struggle so much with monads, and as a result, why so many of those tutorials exist.

  • Probabilistic programming in Haskell by Reuben Cohn-Gordon

    I’ve been doing some spring cleaning on the probabilistic programming library monad-bayes over the summer, and am putting together a website with tutorials and examples.

  • Profiling non-CPU time in Haskell by Facundo Domínguez

    In this post I’m discussing a bit the limitations of the GHC profiler, and I’m announcing timestats, a simple profiling library that you might want to grab when everything else fails.

  • Python’s Print In Haskell by Yair Chuchem

    I’m writing this post because I’m currently considering a similar solution for processing the types AST of Lamdu.
