After midnight I noticed that the Chromatopelma cyaneopubescens sling I keep was nearly upside down in its webbing; a sign it's about to molt. When I got up, just over 8 hours later, I took a photo of the freshly molted tarantula.
The previous and first time this spider molted in my care was the 27th of April, 2020.
Now I have to wait about a week before I can feed the little spider; it first has to harden out its fangs.
There will be linear types in GHC 8.12. But don’t expect a finished product. This is our very first iteration, an MVP as it were. This is as minimal a set of features we think can be useful for anybody. But it’s still very much aimed at early adopters and eager tinkerers.

Template Haskell (TH) is a powerful tool for specializing programs and allows shifting some work from runtime to compile time. It can be a bit intimidating to use for beginners. So I thought I would write up how to use TH to turn certain kind runtime computations into compile time computations.
In particular we will turn the initialization of a fully static data structure into a compile time operation. This pattern works for many data structures but we will look at
IntSetin particular.

I’ve never worked as a professional frontend developer, so even though I’ve been writing HTML/CSS/JS for 15 years for little side projects, all of the projects have been pretty small, sometimes I don’t write any Javascript for years in between, and I often don’t quite feel like I know what I’m doing.
Partly because of that, I’ve leaned on libraries a lot! Ten years ago I used to use jQuery, and since maybe 2017 I’ve been using a lot of vue.js for my little Javascript projects (you can see a little whack-a-mole game I made here as an intro to Vue).
But last week, for the first time in a while, I wrote some plain Javascript without a library and it was fun so I wanted to talk about it a bit!
