here are the latest set of urls for the apple 4k sdr videos/screensavers ( https://9to5mac.com/2018/09/17/tvos-12-features/ ) which includes the nasa/ISS space flyovers:

the url was found here:

JohnCoates/Aerial#463 (comment)

quote:

"The format changed somewhat; you need to extract the JSON out of here https://sylvan.apple.com/Aerials/resources.tar. The JSON includes the URLs to the videos and the time markers for the tvOS 12 captions as a dictionary, keyed by time. The values of this dictionary are keys which can be found in the strings plists."

I hate when my images turn out like this:

import cv2 # opencv
import numpy as np

font_scale = 1.5
font = cv2.FONT_HERSHEY_PLAIN

# set the rectangle background to white
rectangle_bgr = (255, 255, 255)
# make a black image
img = np.zeros((500, 500))

How To - Upload and add Images to markdown files in Gist

Markdown files allow embedding images in it. However it requires the image to be hosted at some location and we can add the url of the image to embed it.

Example: ![Alternate image text](https://someurl/imagelocation/image.png)

We can use services like imgur or other services to host the images and use the hosted URL.
