set -e, -u, -o, -x pipefail

The set lines

• These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing.
• With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.

• set -euxo pipefail is short for:

set -e
set -u

Remove All Subscriptions from a Specific Github Organization

This script will delete all the subscriptions in your account for the Github Organization passed to it.

This script was created when I took a new job, and my notification settings inadvertantly subscribed me to all 600+ of their repos. I wanted a better signal to noise ratio in my notifications, but I didn't want to click the "Unwatch All" button, which would remove my subscriptions to repos outside my new employer's org.

How To

1. Create a Personal Access Token with the "repo" scope, and expose it as the GITHUB_PERSONAL_ACCESS_TOKEN environment variable:

$ export GITHUB_PERSONAL_ACCESS_TOKEN=

(UPDATE (22/3/2019): Added some corrections provided by the original author.)

Writing your own OS to run on a handmade CPU is a pretty ambitious project, but I've managed to get it working pretty well so I'm going to write some notes about how I did it.
