Expanding the readme would be a good idea
The readme does not show any explanation as to what the code does, nor sample output.
It may be obvious to those who know and understand Go. However, seeing as this code has been linked to from Stack Exchange (in an answer that is about to be deleted due to lack of info/details), it might be a good idea to expand upon your readme - just to widen your audience.
Just a thought.
Your code did not running in sudo access. I have change your code and attached below
