Issue 165 2019-06-27
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.
How to Replace React Components With PureScript’s React Libraries by Thomas Honeyman
PureScript helps reduce bugs and improve the stability of complex applications. Learn how to incrementally take over a small React application using Purescript’s React and React Basic libraries while writing idiomatic code in both languages.
Render Quake 3 Arena maps with Elm and WebGL! by Andrea Peltrin
Hi folks, I would like to show you a pet project I’ve been working on during the past weeks. It’s a Quake 3 Arena map renderer, written entirely in Elm and WebGL.
An Applicative for Transactional Validation by Phil Freeman
Suppose you would like to perform multiple validations on your data before you write it to the database or some other store. In a relational database, there is a simple solution which satisfies the constraints: open a transaction, perform all validations and writes in the transaction, and commit.
Complete overkill or exactly right? Deploying a static site using nix by Matthew Pickering
This post is a question about whether the combination of nix, Cachix, Travis CI, haskell.nix and Hakyll was the perfect solution to these constraints or an exercise in overkill.
Hacking on GHC Has Never Been Easier! by Vaibhav Sagar
I wanted to focus on a small part of his presentation, which is about loading GHC into GHCi and using ghcid to automatically reload GHC on changes.
Haskell Fan Site by Ben Lynn
Weary and wary, I tend to dismiss the latest programming paradigm as a passing fad. I was astonished when I found an exception: Haskell.
HTTP/2 server library in Haskell by Kazu Yamamoto
I’m trying to develop QUIC in Haskell. In short, QUIC is a fast and reliable transport protocol based on UDP. You can think of it as TCP2. HTTP/2 over QUIC is now called HTTP/3.
Implement With Types, Not Your Brain! by Sandy Maguire
My favorite part is that having a strong type system means I don’t need to use my brain to do programming.
Lessons learned while writing a Haskell application by Gabriel Volpe
In this blog post I’ll try to share what I have identified as good practice so far and what are my personal recommendations when writing a Haskell application.
My suggestion to use Haskell is not just me being an asshole, although that does make it more fun for me. I will now try to explain in all seriousness and in all the honesty that I can muster what my opinions on languages are and why I have them.
Including but not limited to: Software Engineers/Researchers, Project Managers, Hardware Engineers, Software Integration Engineer.
We collaborate with organizations like NASA, DARPA, and AWS to explore blue sky ideas and turn them into usable technology. Some of the things we’ve worked on in the past: Formal methods, static analysis, cryptographic algorithms, abstract interpretation, type theory, formal verification, reinforcement learning, autonomous systems assurance, communication security, cyber-deception for network defense, DDoS defense, provable hardware security, and statistical anomaly detection for detecting advanced persistent threats. We think working here is awesome; see lifeatgalois.com.

Package of the week
This week’s package of the week is eventlog2html, a tool for creating interactive visualisations of eventlogs. In particular, it creates interactive charts from the heap profiling events.
