Wiring up a Google Form to GitHub is not that difficult with a little bit of Apps Script automation. All you need is a Google account, a GitHub account, and a web browser...

Set up your GitHub Personal Access Token

Personal access tokens provide an easy way to interact with the GitHub API without having to mess with OAuth. If you don't already have a personal access token with repo or public_repo access, visit your GitHub settings page and generate a new token.

Be sure to copy your token some place safe and keep it secure. Once generated, you will not be able to view or copy the token again.

Set up the Form & Spreadsheet

1. Create a Google Form.

# script to remove stylesheets, style tags, and inline styles from an HTML file
# 1. remove <link rel="stylesheet" ...>
# 2. remove <style> ... </style>
# 3. remove style="..." attributes
# notes:
#   perl "0777" is so that perl sees newlines as "any character" (so <link> can wrap onto new lines)
#   "|gms" helps with the same thing. see https://regex101.com/
# example:
#   ./naked.sh index.html > index-naked.html

How to run things as a service on Ubuntu

I run things on my server. I'd like to run them in the background, so they restart when the server restarts.

I was running them "in the background" with tmux, which I had to set up again every time the server restarted. This was annoying. So, here I run them as a service.

I had a vague knowledge of services, because some things I use are one, like nginx and murmur for mumble.
