I always forget these steps and have to google for them, even though they're super simple

Prereq:

• pip install gsutil
• gsutil config, have your project id ready.

1. tar --create --verbose --xz --file images.tar.xz /directory/containing/images/*
2. gsutil cp images.tar.xz gs://<bucket name>

DirectTV Now added a FreeVIEW thing where you can watch some tv shows for free, but they don't show you only the shows that are available on "FreeVIEW", because that would be too convenient.

Luckily, they helpfully mark these subscriber only shows with a badge on the /watch/shows endpoint.

Here's a bookmarklet to hide the subscriber only shows.

javascript:document.querySelectorAll("[data-label='SUBSCRIBE']").forEach( (el) => { el.parentNode.parentNode.parentNode.parentNode.style.display = 'none'; });

Scenario

You have a large audio file that has been split into multiple mp3s.

Goal

You want to merge these and convert to a m4a (optional) so that you can use it with https://github.com/scottopell/audiobook-podcast

Steps:

# Combine MP3s
ffmpeg -i "concat:$(ls *.mp3 | tr '\n' '|')" -acodec copy out.mp3

// This took me way too long to figure out.
// Needs node 8.4.0 or greater to work (I think, based on https://github.com/nodejs/node/issues/7593#issuecomment-322966866)
// The magic sauce here is that react-scripts-ts/scripts/test.js creates an inline jest config
// that it passes through. This does things like map css files properly, so if you try to use
// jest directly then it won't work.
