Just wanted to let you know, there's an error in your feed for Planet Python.

If you go to http://planetpython.org/ and scroll down to your entry for "Running Bottle Apps in Docker Containers on macOS", you will see that the URL is https://www.fullstackpython.com/first-steps-bottle-web-apps-docker-containers.html

However, that URL gets a 404. The correct URL has a /blog/ in the middle.

It's always been that way, as far as I am aware.
