	/*****************************************************************************
	* QuantCup 1: Price-Time Matching Engine
	*
	* Submitted by: voyager
	*
	* Design Overview:
	* In this implementation, the limit order book is represented using
	* a flat linear array (pricePoints), indexed by the numeric price value.
	* Each entry in this array corresponds to a specific price point and holds
	* an instance of struct pricePoint. This data structure maintains a list

xdp screen cast example, modified to pipe to ffmpeg

	mkfifo /tmp/gfifo

	./xdp-screen-cast-ffmpeg.py & # or run in another terminal
	# Note the gstreamer pipeline
	# 'pipewiresrc fd=%d path=%u ! videorate ! video/x-raw,framerate=60/1 ! videoconvert ! filesink location=/tmp/gfifo'
	# I specified a 60/1 frameerate. You can do other pre-processing here, or offload it to ffmpeg.

	# Encode the stream and pipe to netcat
	# note: must specify correct resolution here
	# we can now use h264_nvenc, mpegts, and anything else ffmpeg has

VSCode config to disable popular extensions' annoyances (telemetry, notifications, welcome pages, etc.)

	// I'm tired of extensions that automatically:
	// - show welcome pages / walkthroughs
	// - show release notes
	// - send telemetry
	// - recommend things
	//
	// This disables all of that stuff.
	// If you have more config, leave a comment so I can add it!!

Zoom claims that meetings are end-to-end encrypted in their white paper and marketing materials, but meetings are only encrypted in transit, and are available in plaintext to Zoom servers and employees. (source)
