Add missing log function

Without a logging solution, we do silly things to just make some kind of noise
such that someone may hear us, come to our aid, and save us from ourselves.
Mankind has now used radio broadcasting for over a century and so our RF
emissions have traveled more than 100 lightyears from Earth. At that distance,
they are very faint and observers would need to have very sensitive equipment
specifically directed at us. Who's listening?
