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.

1. Open the Google App Engine -> instances section of the Google Cloud Platform (GCP) console.

2. 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.

When programming apps for Android, you usually want to test them on real Android devices.
This little gist describes how to do so using Ubuntu 14.

First, you need to download and install the Android development IDE (http://developer.android.com/sdk/index.html) and create an Android project which you want to debug.

Next, you need to setup the debugging mode on your Android device. Starting in Android 4.2 you need to enable the developer options first: 1) Go to settings 2) Go to About Phone 3) Tap the build number 10 times (or more, not sure ;)) and you will get the notification that you enabled it.

Then go to the developer settings and enable the debug mode for your phone. 

Now you think you can just plug it into your USB mode? - Nope.
