This thread will be a dumping ground for the nifty scripts ChatGPT made me, so I don’t lose them, also to share them with anyone that might want to do the same or a similar task.
This script will list all the droplets in Digital Ocean, along with their tags. It then takes the tag and passes it to a cURL command that uses the Tailscale API to remove that device from Tailscale. In the last step, all the droplets in Digital Ocean are deleted.

This script creates a bunch of Digital Ocean droplets. It’ll make up to 10 of the cheapest droplets, 1 per region.
It will also add the machine to Tailscale and place a tag on the droplet on Digital Ocean the Tailscale device ID so when it’s time to delete the droplet, we can use that tag to also remove it from Tailscale.

This python script goes through a directory of ripped Bluray discs and looks at each disc to find the main feature (usually the largest m2ts file) and then uses ffprobe to find the length of that feature.
Once it has the biggest file and the length, it passes that info on to ffmpeg to take 9 random screenshots of the video and saves them in a directory with the same name as the disc.
