How does this work?

  Each button is a separate image that links to my website, which records the letter, and then redirects you back to GitHub. The top part of the screen is dynamically generated, and you can view it directly here: https://kbd.jse.li/screen.gif https://kbd.jse.li/screen.gif

    Doesn't GitHub cache fetched images? Any tricks required to get GitHub to refresh the image?

      For most use cases, like for CI badges, setting cache-control and etag headers will suffice, but GitHub still caches it (just for a shorter time? I don't know the specifics). Luckily, you can request that they purge their cache for a specific file [0] so I've got a goroutine that calls it once per second [1] [0] https://docs.github.com/en/github/authenticating-to-github/about-anonymized-image-urls#removing-an-image-from-camos-cache https://docs.github.com/en/github/authenticating-to-github/a...
