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.
HF Technical Track Elections Results - 2021 by Emily Pillmore
I’m pleased to announce that the Haskell Foundation Technical Track (HFTT) Elections have concluded, and we have a brand new set of members.
Induction without core-size blow-up by Edsko de Vries & Adam Gundry
The approach described there does however not directly apply to the case of anonymous records. This is the topic we will tackle in this part 2.
Into the Future by Andrew Boardman
In the previous post I talked about what the Haskell Foundation has been up to for the first seven months, now I want to discuss where we’re heading.
Proving Equivalence of Polysemy Interpreters by Sandy Maguire
Last week we looked at how to do property-testing for a
polysemyeffects’ laws. Today, we’ll investigate how to show that two interpretations are equivalent.
Template Haskell — Use Cases by Arnau Abella
In this blog post, we are going explore a bunch of interesting Template Haskell’s use cases: Type Class Derivation, N-ary Function Generation, Compile-time Static Input Validation, Arbitrary IO at Compile Time.
We are currently accepting applications for full-stack software professionals to join our small, but talented, multidisciplinary team.
Trying to hire a Haskell developer? You should advertise with us!
In my last post, I showed how we can solve Modulo Solitaire (and hopefully other BFS problems as well) using a certain API for BFS.
Denotational homomorphic testing by Divesh Otwani
I ended up using something that I’ve been calling denotational homomorphic testing. In this post, I’ll walk through how I ended up with this and why this is legitimately helpful.
Epsiode 3: Gabriella Gonzalez by The Haskell Interlude
We talk about Dhall, Nix, and Haskell, learn why Gabriella’s packages are sometimes called after characters of computer games, and get to know her elevator pitch for educating Haskell.
Initial and final encodings of free monads by Li-yao Xia
Free monads are often introduced as an algebraic data type, an initial encoding. Thanks to that, the term “free monads” tends to be confused with that encoding, even though “free monads” originally refers to a representation-independent idea.
Using IO without the IO Monad! by Monday Morning Haskell
In this article we’re going to demonstrate how we can get limited IO effects within our function. That is, we’ll write our type signature to allow a couple specific IO actions, without opening the door to all kinds of craziness.
Virtual Haskell Cohack by Chris Smith
Tackle a personal project, ask or answer your Haskell questions, help a newbie get up and running (or get help yourself), or start a new collaboration with other community members.
