How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

Nginx: stat() failed (13: permission denied)

from https://stackoverflow.com/questions/25774999/nginx-stat-failed-13-permission-denied

Nginx operates within the directory, so if you can't cd to that directory from the nginx user then it will fail (as does the stat command in your log). Make sure the www-user can cd all the way to the /username/test/static. You can confirm that the stat will fail or succeed by running

sudo -u www-data stat /username/test/static

	git fetch -p
	git fsck --full

	Each YouTube video has 4 generated images. They are predictably formatted as follows:
	http://img.youtube.com/vi/<insert-youtube-video-id-here>/0.jpg
	http://img.youtube.com/vi/<insert-youtube-video-id-here>/1.jpg
	http://img.youtube.com/vi/<insert-youtube-video-id-here>/2.jpg
	http://img.youtube.com/vi/<insert-youtube-video-id-here>/3.jpg
	The first one in the list is a full size image and others are thumbnail images. The default thumbnail image (ie. one of 1.jpg, 2.jpg, 3.jpg) is:

	http://img.youtube.com/vi/<insert-youtube-video-id-here>/default.jpg
	For the high quality version of the thumbnail use a url similar to this:

	-- UUID to BYTEA:

	SELECT DECODE(REPLACE(CAST(uuid_field AS TEXT),'-',''), 'hex') FROM table;

	-- BYTEA to UUID:

	SELECT CAST(ENCODE(bytea_field, 'hex') AS UUID) FROM table;

	-- BONUS --
