Motion Extraction with JavaScript (Interactive Demo)

This code demonstrates a simple motion extraction technique using JavaScript and HTML5's video and canvas elements. It captures frames from either a live camera feed or an uploaded video, inverts the colors, and blends consecutive frames to isolate motion changes. Users can adjust resolution, delay between snapshots, and toggle a freeze-frame mode to lock the reference frame, allowing for a clear view of motion in relation to the frozen frame.

Inspired by CodeParade's video, this project highlights the power of real-time video processing using basic browser technologies.

Things to consider when building a cross-platform game:

Minimum button sizes for touch displays and small screen (eg steamdeck, mobile, nintendo switch hand held mode) is about 60 pixels. Anything smaller will fail lotcheck (Apple, Android, Nintendo).
Visual feedback of UI interactions (Android, Apple -> they'll reject a feature/showcase of your game if you don't have this).
Safe area/layout considerations. Avoid things like notches and app switch "chin". If you're making a game that can render edge to edge/without letter boxing, test at an aspect ratio of 21:12 (1680x960). Your safe are should be centered with an aspect ratio of 16:9 (placement of UI controls should always be in the safe area or they may be inaccesible because of notches and beveled edges).
Button input detection with keyboard, touch, and gamepad. Navigation using keyboard, gamepad, mouse.
Anything below 22px font size is pretty much unreadable on small screens (mobile, Steam Deck, Switch Lite).
Text fields is a world of p

Tuning Windows 10 for Slow Machines

This guide is for those who dares to install Windows 10 on slow netbooks (1GB of RAM).
Though Windows update program is over, you still may use old Windows product keys from license stickers to install Windows 10 on old machines.

	# Windows XML String Resolver
	# Author: ThioJoe
	#
	# Purpose: This script takes an XML file that contains string references (e.g., "@shell32.dll,-1234")
	# and resolves them to their actual string values. It's particularly useful for working with
	# Windows resource files or any XML that uses similar string reference formats.
	#
	# How to Use:
	# 1. Open PowerShell and navigate to the path containing this script using the 'cd' command.
	# 2. Run the following command to allow running scripts for the current session:

	# Get All Shell Folder Shortcuts Script (Updated 8/10/2024)
	# Original source: https://gist.github.com/ThioJoe/16eac0ea7d586c4edba41b454b58b225
	# This PowerShell script is designed to find and create shortcuts for all special shell folders in Windows.
	# These folders can be identified through their unique Class Identifiers (CLSIDs) or by their names.
	# The script also generates CSV files listing these folders and associated tasks/links.

	# How to Use:
	# 1. Open PowerShell and navigate to the path containing this script using the 'cd' command.
