Bitcoin Full Node on AWS Free Tier

Launch one T2 micro instance, using Ubuntu 14.04 LTS AMI.
Open SSH and Bitcoin Protocol TCP ports: 22, 8333.
Attach 40GB EBS (General-Purpose SSD) volume for blockchain storage to /dev/sdf.

The pricing should be ~3$ for the first year (assuming 30GB upload per month). See here for more details.

Two of the most useful shortcuts utilize the Fn (function) keys. It is therefore recommended that you enable the "Use all F1, F2, etc. keys as standard function keys" option [System Preferences > Keyboard].
Be sure to enable the Mac OS X 10.5+ keymap in Android Studio [Preferences > Keymap].
A fairly complete shortcut list can be found here.
