Mostly just for me to remember stuff

Python

I wanted a json utc datetime for a MQTT payload. Found the arrow module that is much like moment.js for javascript.

import arrow
print (arrow.get(arrow.utcnow()).for_json()

results in: "2015-08-27T15:03:07.427351+00:00" I'd like to trim it further and replace the +00:00 with Z. ??? and less precision on the seconds.

firewall-cmd --permanent --add-port=3000/tcp
# be sure to reload
 firewall-cmd --reload
