The compiler for ESP32 is not installed. (Why is this not in the turorial???) Basically follow https://randomnerdtutorials.com/installing-the-esp32-board-in-arduino-ide-windows-instructions/. You can have both "Additional Boards Manager URLs" by concatening them with "," like: https://dl.espressif.com/dl/package_esp32_index.json,https://raw.githubusercontent.com/e-radionicacom/Croduino-Board-Definitions-for-Arduino-IDE/master/package_Croduino_Boards_index.json Install the package "esp32" by "Espressif Systems.

This config allows the usage of a dedicated interface from wireguard (or openvpn or whatever) to be used by programs without tunneling all internet traffic to it (default gateway). The program must be able to bind to a specific network interface (the one from wireguard or openvpn). Since only one default route can exist, we use the fact that with iproute2 it is possible to have muliple routing tables where one default route for each table is allowed. The findigns are based on the article here: https://www.thomas-krenn.com/de/wiki/Zwei_Default_Gateways_in_einem_System

Pre-defined (rather "named") tables can be found in /etc/iproute2/rt_tables. This file holds a mapping between the id and the name (separated by whitespace). In commands these names can be used instead of the id but this is not required but might be easier to remember what table is used for what connection. Pretty much any free id can be used. If you look closely when using the wireguard default routing, you can see table 51821 in the output

Add this to the JVM parameters: --add-modules jdk.incubator.foreign -Dforeign.restricted=permit

WARNING: unbinding the amdgpu driver does currently NOT work! https://gitlab.freedesktop.org/drm/amd/-/issues/1081

Writeup based on Ubuntu 20.04.2 LTS with xfce and two GPUs from AMD with the amdgpu driver (open source).

Pre-requisites

Pre-requitsite is that you have a basic understanding what are you doing and that you have your IOMMU working.

	So for anyone that has raged hard over this and cursed the people that made Jigsaw into oblivian becuase this fucking shit makes only problems.

	Trying to launch Openjfx with java 11, 12 or whatever in IntelliJ with maven only gives
	```
	Caused by: java.lang.IllegalAccessError: class com.sun.javafx.fxml.FXMLLoaderHelper (in unnamed module @0x6804e207) cannot access class com.sun.javafx.util.Utils (in module javafx.graphics) because module javafx.graphics does not export com.sun.javafx.util to unnamed module @0x6804e207
	```
	in your luckyest moment (Ignoring a lot of other shit error messages).

	I may have found out what the hell it is doing. So IntelliJ launches an "Application" either with everything on the classpath or with module path support.
	If your app has NO module-info.java then everything is put on classpath which makes unnamed modules and the module definition inside the dependencies are then completely wrong and dont work.

	#!/bin/bash
	# This file is in the same folder as the other file below. Is called by youtube-dl after the download as "processor".
	# We get the filename as parameter and extract the video id from it. Then we pass it to "tcd", the chat downloader.
	# Finally, we change the filename of the downloaded chat to match the filename of the downloaded video.
	filename="$1"
	id=$(echo "$filename" \| sed -En 's/v([0-9]+)-.*/\1/p')
	tcd --format irc --video "$id"
	mv "${id}.log" "${filename%.*}.chat"

	struct va_list; // shitty hack
	typedef struct va_list *va_list;

	typedef int jint;
	typedef long long jlong;
	typedef signed char jbyte;

	typedef unsigned char jboolean;
	typedef unsigned short jchar;
	typedef short jshort;

	@SneakyThrows
	public static HttpRequest.Builder applyProxy(HttpRequest.Builder httpRequest, URI proxy) {
	URI originalUri = httpRequest.build().uri();
	String hostname = originalUri.getHost();
	URI proxyUri =
	new URI(
	"http",
	originalUri.getAuthority(),
	proxy.getHost(),
	proxy.getPort(),

	You might have the circumstance that you have a program sandboxed in a VM in VirtualBox.
	But you want to control the program with shortcuts as if it was running on the host.
	An example would be voice chat software where you want to toggle the microphone.

	You need the HEX values of the keyboard scancodes ("the description of the location on the keyboard", not the character to press!).
	Search for "scancode list" on google; e.g. http://www.winfaq.de/faq_html/Content/tip1500/onlinefaq.php?h=tip1576.htm

	# send ctrl (left) + shift (left)
	VBoxManage controlvm <vmName> keyboardputscancode 1D 2A
	# send "m"

	//First argument is how much is consumed (in millibuckets) in one go and the second how long it lasts (in ticks). NOT balanced, just an example
	mods.tconstruct.Fuel.registerFuel(<liquid:pyrotheum> * 50, 25);
