I heard from GitHub Two-Factor Authentication](https://github.com/blog/1614-two-factor-authentication) nearly a couple of days ago when I was reading my RSS feed. I enabled it and couldn' push to any of my repositories anymore. Learn in this blog post how to fix it.

Two-Factor Authentication

"Is a process involving two stages to verify the identity of an entity trying to access services in a computer or in a network". Github solves this authentication with sending an SMS to a device which wants to push to their platform.

(ns slack
  (:require [clj-http.client :as client]
            [clojure.data.json :as json]))

(defn send-to-slack
  "Sends a simple message to slack using an 'incoming webhook'.
   url will be of form: https://myapp.slack.com/services/hooks/incoming-webhook?token=mytoken .
   (Exact url you should use will appear on the slack integration page)
   text will be any valid message.
   This implementation could be expanded if you wanted to specify channel, username, etc.

# Let's say you were stupid and used the postgres account for something you
# shouldn't have, so you have a database owned by postgres, with all objects
# inside owned by postgres.  You regain sanity and want to transfer the
# ownership to an account that isn't a database superuser.
# 
# In most cases, reassigning ownership is as simple as using
# REASSIGNED OWNED.  However, that does not work if you are using the
# postgres account, so you have to alter the ownership manually.
#
# First, make sure you connect to the database using the postgres account.
