How to add imperative programming to a pure functional language
===

Many people bemoan languages such as Haskell for not supporting imperative
programming; they decry the need for math in their computer science.

![Math? In my computer? Yeah right.](http://i.imgur.com/YDIaEPB.jpg)

I'm here to tell you that not only does Haskell make imperative programming a
cinch, but safe and correct as well. Follow along! This post is written in

Let's Encrypt on Ubuntu 14.04, nginx with webroot auth

This document details how I setup LE on my server. Firstly, install the client as described on http://letsencrypt.readthedocs.org/en/latest/using.html and make sure you can execute it. I put it in /root/letsencrypt.

As it is not possible to change the ports used for the standalone authenticator and I already have a nginx running on port 80/443, I opted to use the webroot method for each of my domains (note that LE does not issue wildcard certificates by design, so you probably want to get a cert for www.example.com and example.com).

Configuration

For this, I placed config files into etc/letsencrypt/configs, named after <domain>.conf. The files are simple:
