Haskell Weekly

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.

Featured

• Another weekend side project: Spatial voter modeling in Haskell by Chris Smith

  I now have a reasonably realistic statistical model of voting behavior, as well as analysis tools for visualizing and analyzing election systems and methodologies and their practical effects.

• Fearless Tinkering is Functional by Heneli Kailahi

  Is functional programming worth learning? This series is the sales pitch I wish I had received when first being introduced to the world of functions.

• From Fibonacci to Haskell with some spicy mathematics by Timothy Samson

  Here’s a story about math and programming, with the Fibonacci sequence as it’s protagonist.

• MySQL Persistent Support for Haskell on Windows by Jappie Klooster

  This is a small instructional blog post, primarily for my own reference, on how to get MySQL support for programs on Windows. These steps are for native Windows support. There’s no WSL involvement.

• Using Haskell with devenv.sh by Domen Kožar

  Most of our code is written in Haskell, so I’d love to support it as a first-class citizen.

• Why I use the Twain web framework by Gil Mizrahi

  Recently I’ve been using Twain for all of my newer web apps instead of Scotty and previously Spock, and I wanted to share why.

In brief

• Haskell Foundation DevOps Weekly Log, 2023-07-05 by Bryan Richter

  In the last week, I have finished splitting my spurious failure-handling bot into its own package, and I am nearly finished implementing retry backoff.

• IOG GHC Update #13 by IOG

  Biweekly update from the GHC DevX team at IOG.

Show & tell

• GHCup version 0.1.19.3 by Julian Ospald

  This release mainly introduces nightly support.

• monoidal-stats by Chris Smith

  I just pulled this out of the voronoizer code I wrote a few weeks ago, because I ended up wanting it for another side project.

• purely-poker by Ola Berglund

  I just finished a weekend project, a poker equity evaluator, to practice parallelism (turns out it was ridiculously easy, as can be seen on line 99).

• Stamina by Domen Kožar

  A library for retrying in Haskell has been brewing in my mind for a few years now, based on everything we’ve learned so far.

• toml-parser by Eric Mertens

  I’ve updated my old TOML package with a number of features that I think make it unique among the other offerings on Hackage.
