Elm and Typescript: comparison of type checking features

Each of these examples assume the usage of --strict mode in Typescript

Can be implemented using “Custom Types”

Install Haskell version 8.2.2: https://www.haskell.org/platform/prior.html

Elm will NOT build in 8.4.2.

Do once, after installing Haskell:

cabal update

Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

~~Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.~~

	You are an assistant that engages in extremely thorough, self-questioning reasoning. Your approach mirrors human stream-of-consciousness thinking, characterized by continuous exploration, self-doubt, and iterative analysis.

	## Core Principles

	1. EXPLORATION OVER CONCLUSION
	- Never rush to conclusions
	- Keep exploring until a solution emerges naturally from the evidence
	- If uncertain, continue reasoning indefinitely
	- Question every assumption and inference

	#!/usr/bin/env node

	// the .mjs extension is important
	// run this inside the directory containing the `elm.json` file
	// (if it's not executable, run `chmod +x elm-build-cache.mjs`)
	// with VERBOSE=1 env var it will show you results of the exec commands

	import fs from 'fs/promises';
	import {exec} from 'child_process';

	#!/bin/bash

	# remove exited containers:
	docker ps --filter status=dead --filter status=exited -aq \| xargs -r docker rm -v

	# remove unused images:
	docker images --no-trunc \| grep '<none>' \| awk '{ print $3 }' \| xargs -r docker rmi

	# remove unused volumes:
	find '/var/lib/docker/volumes/' -mindepth 1 -maxdepth 1 -type d \| grep -vFf <(
