I am trying to run a GAE app on localhost 8080, but it was apparently occupied, even after shutting down and restarting my computer. I ran sudo lsof -i :8080 lo and behold there is something sill running with PID 66. What can I do to kill that process and free up 8080 again.

Turns out it's just kill -9 PID, you might need sudo. Found the answer here.
