Installing Flask on a live Linux (Ubuntu) server:
#	you need a paypal or a credit card
	sign up for a domain name. use google e.g., netregistry / crazydomains, about $15 per year
	sign up for cheapest web hosting plan. i use binary lane $4 per month
	write down IP address and root password
	point domain (nameserver) to IP address
	point registered domain name to nameservers
	change ubuntu (linux) root password. if you dont like the browser container window use PuTTY
	update and upgrade your server OS
	install Apache2 HTTP server
	use Certbot to enable TLS on HTTP (aka HTTPS)
	use SSH for file transfer. i like FileZilla
	sudo update-alternatives --set python /usr/bin/python3.6 if you dont want 2.x
	(pip) install flask
	use WSGI to forward requests to flask
