Custom data pack structures with jigsaws in 1.18.2

(Last updated: 1.18.2)

This is technically a shameless rip/edit of misode's guide that shows the traditional use of newly implemented custom structure system. I myself want to tackle the jigsaw aspect a bit, hence i'm making my own guice based on his. I will show how to create a data pack that adds custom structures to the world that also utilize jigsaw blocks. So treat this as a basic jigsaw guide in world generation. There is also a data pack download of this first example.

Always leave the world and rejoin to apply the new changes! Because traditional /reload or /datapack disable & enable do not refresh changes in worldgen files!

EXAMPLE 1 - Creating a structure that uses jigsaws

Let's make a simple house with a basement and a road that will lead away from the h

Known issues

Game can randomly crash due to atomic operation failure. (MC-249933)
You cannot launch the game without authenticating/in offline mode; add --uuid=123 run arg to fix.

Changes

Random replaced with AbstractRandom

java.util.Random has been replaced with AbstractRandom in most of the code. This interface, previously under net.minecraft.world.gen.random package and now under net.minecraft.util.math.random, provides most of the operations Random supports. There are 3 vanilla implementations based on Java Random:

SimpleRandom: Not thread safe at all.

Introduction

Let me start by clarifying that the following doesn't exclusively apply to Debugify, but they serve as an excellent illustration of the heinous behavior outlined in the following. The mods in question shall therefore be collectively referred to as "Scummy Mods".

Scummy Mods are mods that incorporate or outright copy foreign code bases, without permission from the original author. They commonly state to either "replace" or "include" the original work, if any mention is given at all. Developing a mod is not easy. Many mod creators sacrifice significant chunks of their personal time and resources to their creations, essentially for free. Curseforge offers a symbolic compensation for the hours poured, but it's usually insignificant and just a nice bonus.

The Problem

The majority of the original projects are still in development. Since the creators behind Scummy Mods typically do not understand the code they copied to begin with, they lack the knowledge required to eliminate the bugs that will

A Short IPv6 Guide for Home IPv4 Admins

This guide is for homelab admins who understand IPv4s well but find setting up IPv6 hard or annoying because things work differently. In some ways, managing an IPv6 network can be simpler than IPv4, one just needs to learn some new concepts and discard some old ones.

Let’s begin.

First of all, there are some concepts that one must unlearn from ipv4:

Concept 1

	const require = (url) => {
	const head = document.getElementsByTagName('head')[0];
	const script = document.createElement('script');
	script.type = 'text/javascript';
	script.src = url;
	head.appendChild(script);
	}

	require("https://cdn.jsdelivr.net/npm/hyperformula/dist/hyperformula.full.min.js");

	.json-skin { font-family: monospace,'Courier'; }
	.json-skin ul { padding-left: 0; display: inline; list-style: none; }
	.json-skin .elm-arbol { display: inline; }
	.json-skin li { padding-left: 20px; }
	.json-skin ul.elm-object::before { content: '{'; font-weight: bold; }
	.json-skin ul.elm-object::after { content: '}'; font-weight: bold; }
	.json-skin ul.elm-array::before { content: '['; font-weight: bold; }
	.json-skin ul.elm-array::after { content: ']'; font-weight: bold; }
	.json-skin span.elm-more {cursor: pointer; }
	.json-skin span.elm-more::before { content: '...'; font-weight: bold; color: gray; }

	# Make sure to have OpenSSH setup in Termux as well as setting a password with `passwd`
	# Requires https://github.com/upa/mscp and adb platform tools on your local machine

	init_sshd() {
	adb shell -t "run-as com.termux files/usr/bin/bash -lic 'export PATH=/data/data/com.termux/files/usr/bin:$PATH; export LD_PRELOAD=/data/data/com.termux/files/usr/lib/libtermux-exec.so; sshd'"
	adb forward tcp:8022 tcp:8022;

	stop_sshd() {
