Step 1: Install Ubuntu

Step 2: Add a deploy user and optionally a user for yourself.

Assuming you're logged in as root add these users and login as "not root."

adduser deploy
adduser [yourname] #optionally
vim /etc/group
# add your users to the sudo group like so: 
  sudo:x:27:isaac,deploy
vim /etc/ssh/sshd_config
# add to file or if they exist set the flags to no.

The problem

If you read enough files created on a windows box you'll eventually run into this. ""\xEF\xBB\xBFyour expected string" instead of "your expected string". I recently ran into again while parsing some csv files exported in windows. In order to parse the string you'll need to remove what is called a Byte Order Mark.

Solution

Just search for "\xEF\xBB\xBF" and remove it.

One of the only differences I've noticed is installing mysql is slightly different.
