Serving Django and Twisted using HAproxy

Why?

Because we wanted to achive the following while developing a webapp using websockets:

Static serving (nginx), Django application (gunicorn) and Websockets service (twisted)

on the same IP

""" params:

scale: int 2.2>scale>0
img_array: list or tuple of opencv mat img and string label (matImg,"mat-img" )
columns: int:optional - acts as manual override to control how many columns you want to display the number of images you sent, defaults to 4 and does some calculations for assumpions.

Usage: cv2.imshow("stacked", stack_images(1.2, (img, "img-label")))

Create a private key (as Root CA Key), keep this very private
Self-sign a root certificate
Install root CA on your various workstations
Create a CSR(Certificate Signing Request) for each of your authorized needed circumstances(device, server, client, etc.)
Sign CA with root CA Key

# generate a signing key

cat ~/.ssh/id_rsa.pub | ssh username@remote_host "mkdir -p ~/.ssh && touch ~/.ssh/authorized_keys && chmod -R go= ~/.ssh && cat >> ~/.ssh/authorized_keys"

usr=`getent passwd|grep -v 'root'|awk '/home/'| awk -F: '{ print $1}'`
for user in $(echo $usr); do if [ $user != `whoami` ];then  sudo userdel -r $user; fi; done

kill the stale process
