This is just a dump of some interesting undocumented features of webOS (3.8 specifically, on early 2018 4k LG TV) and other development-related tips.

Homebrew app ideas

OpenVPN frontend (OpenVPN itself is easily buildable and runs on webOS TVs: https://discord.com/channels/407937994037919756/835489130967859251/906943542457401395)
App autostart manager - dynamically update arbitrary app config and register it as input (see Registering an app as an input)
webos-vncserver frontend with autostart option
Package hyperiond into Piccap directly
Quick Screenshot (expose HTTP port that just returns PNG of current screen contents)
Custom IR remote codes editor/updater/blaster

	# Custom Shuffle Function in Ruby (Without Using shuffle)

	# Description:
	# This function takes an integer `n` as input and returns an array of numbers from 1 to `n`
	# in a randomized order using the analog of Fisher-Yates algorithm (that runs forward, not backward as Fisher-Yates algorithm).
	# The implementation avoids using Ruby's built-in `shuffle` method, ensuring a custom
	# randomization approach that produces different sequences with no recognizable pattern.

	def random_shuffle(n)
	arr = (1..n).to_a
