System: Debian/Ubuntu/Fedora. Might work for others as well.

As mentioned here, to update a go version you will first need to uninstall the original version.

To uninstall, delete the /usr/local/go directory by:

Open Chrome Developer tools and click the Network tab.
Navigate to the page with the video and get it to start playing.
Filter the list of files to "m3u8".
Find master.m3u8 or index.m3u8 and click on it.
Save the file to disk and look inside it.
If the file contains a single m3u8 master url, copy that one instead.
Run the program m3u8x.
Paste the same m3u8 url in both textboxes (URL and Quality URL) and click "Headers" and set the referral url and user-agent from the request as found in Chrome.

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).

When writing a string of multiple utility classes, always do so in an order with meaning. The "Concentric CSS" approach works well with utility classes (i.e,. 1. positioning/visibility 2. box model 3. borders 4. backgrounds 5. typography 6. other visual adjustments). Once you establish a familiar pattern of ordering, parsing through long strings of utility classes will become much, much faster so a little more effort up front goes a long way!
Always use fewer utility classes when possible. For example, use mx-2 instead of ml-2 mr-2 and don't be afraid to use the simpler p-4 lg:pt-8 instead of the longer, more complicated pt-4 lg:pt-8 pr-4 pb-4 pl-4.
Prefix all utility classes that will only apply at a certain breakpoint with that breakpoint's prefix. For example, use block lg:flex lg:flex-col lg:justify-center instead of block lg:flex flex-col justify-center to make it very clear that the flexbox utilities are only applicable at the

	// keeping the same pattern
	export default await new Promise(async $export => {
	// export the module
	$export({my: 'module'});
	});

	// dropping the Promise all together
	export default await (async () => {
	// await async dependencies
	// export the module
