V8

V8 is Google’s open source high-performance JavaScript and WebAssembly engine, written in C++. It is used in Chrome and in Node.js, among others. It implements ECMAScript and WebAssembly, and runs on Windows 7 or later, macOS 10.12+, and Linux systems that use x64, IA-32, ARM, or MIPS processors. V8 can run standalone, or can be embedded into any C++ application.

SpiderMonkey

SpiderMonkey is Mozilla’s JavaScript and WebAssembly Engine, used in Firefox, Servo and various other projects. It is written in C++, Rust and JavaScript. You can embed it into C++ and Rust projects, and it can be run as a stand-alone shell. It can also be [compiled](https://bytecodealliance.org/articles/making-javascript-run-fast-on

Create croped RTSP live stream from existing RTSP live stream

I needed a croped section of a RTSP live stream from a UniFi Protect camera, since I am filming my yard from a shed and wanted to see a cutout of the front door from my 4K camera.
This article will show you how to enable the RTSP live stream on the UniFi Protect camera, how to setup a streaming server and how to actually execute the processing of the live stream.

Enable UniFi Protect RTSP live stream

The following screenshots are made from UniFi Protect application on version 2.7.18

Go to "UniFi devices"
Click on the desired camera in the camera list

Gitlab Docker / Caddy / Portainer (plus bonus XWiki)

This is how I was able to get Gitlab CE Docker to run behind a Caddy reverse proxy, created from Portainer stack.

This has taken quite a lot of searching, so I figured that I'd write it up in a location that I could easily refer to it in the future.

There are a handful of items that are initially needed here:

Caddy and its network
Portainer

	const esbuild = require('esbuild');
	const { cp, readFile, writeFile } = require('fs/promises');
	const { exists } = require('fs-extra');

	const OutputDIR = './build';
	const InputFile = `./main-source.js`;
	const OutputFile = `${OutputDIR}/node-red.js`;
	const FinalPKG = `${OutputDIR}/package.json`;
	const GotSourceFile = './node_modules/got/dist/source/index.js';
	const GotPackageFile = './node_modules/got/package.json';

	// 3D Dom viewer, copy-paste this into your console to visualise the DOM as a stack of solid blocks.
	// You can also minify and save it as a bookmarklet (https://www.freecodecamp.org/news/what-are-bookmarklets/)

	const SHOW_SIDES = false; // color sides of DOM nodes?
	const COLOR_SURFACE = true; // color tops of DOM nodes?
	const COLOR_RANDOM = false; // randomise color?
	const COLOR_HUE = 190; // hue in HSL (https://hslpicker.com)
	const MAX_ROTATION = 180; // set to 360 to rotate all the way round
