If you're running a Rails app in Google App Engine's flexible environment, it takes a bit of setup to get to a rails console attached to your deployed environment. I wanted to document the steps for my own reference and also as an aid to others.

Open the Google App Engine -> instances section of the Google Cloud Platform (GCP) console.
Select the "SSH" drop-down for a running instance. (Which instance? Both of my instances are in the same cluster, and both are running Rails, so it didn't matter for me. YMMV.) You have a choice about how to connect via ssh.
1. Choose "Open in browser window" to open a web-based SSH session, which is convenient but potentially awkward.
2. Choose "View gcloud command" to view and copy a gcloud command that you can use from a terminal, which lets you use your favorite terminal app but may require the extra steps of installing the gcloud command and authenticating the gcloud command with GCP.

	"Calculate the Shannon entropy, a.k.a. amount of information, in a

	freqencies like that returned by the `clojure.core/freqencies` function.

	(entropy [0 1 2 3]) ; => 2.0
	(entropy {0 2, 1 2}) ; => 1.0
