/*
createReducer() builds a reducer function using an initial state and a map of reducer functions.
Any action whose type matches a key in the reducer map will cause createReducer()'s return value to invoke a method in the reducer map.
If you annotate your dispatch() function as DispatchFor<yourReducerHere>, it will prevent you from passing an event that it's incapable of handling.

This is mostly notes to myself in case I ever do this again.

So, I've been doing a lot of frontend development in Typescript/React, but I'm also interested in Kotlin. I'm a full-stack engineer, so the idea of making a whole application in the same language appeals to me. (I'm aware that backend development in NodeJS exists, but I'm a fan of strict typing.)

So I've been exploring Kotlin's JS backend support.

So anyways, here's how my project is set up right now:

karlrwjohnson

import {Dispatch, SetStateAction, useCallback, useLayoutEffect, useRef, useState} from "react";

/**
 * Object that stores immutable data,
 * allows components to subscribe to changes in that data,
 * and exposes functions to update the state by mapping the previous state to a new state
 *
 * Similar to Redux, except instead of dispatching actions which are consumed by a reducer,
 * it's like you dispatch the reducer functions themselves.

"""
Solution finder for puzzle in Legend of Zelda: Twilight Princess to obtain the Master Sword.

The temple is guarded by a pair of golems. When the player approaches, the ground transforms into a grid of squares.
As the player moves around the board, the golems move in response. The player must maneuver the two golems onto
two specific squares in order to proceed.

This Python script finds a solution in 801 iterations on a breadth-first search of all possible movements.
For some reason, I've annotated how it all works.

Web Development without Toolchains

Yelling at clouds

When I first started playing with web development, I was building toy websites with Microsoft FrontPage and ogling over the cool features on Dynamic Drive. It seemed like files were written by hand in text editors and published directly by copying them to FTP sites.

(Later I found out about PHP and server-rendered sites.)

Configuring Microk8s for remote access

In order to learn about Kubernetes, I've installed Microk8s on Ubuntu Server on an old laptop stashed in my basement. It seemed like a better option than Minikube because Microk8s actually claims to have auto-update. (I really want auto-update because I'm a developer - not ops. I set things up, but I'm bad at maintaining them day over day.)

I got it installed okay, but I ran into trouble connecting to it remotely. In my opinion, the documentation for doing this is SUPER CONFUSING for beginners.
