As of 14.04 Ubuntu no longer has ffmpeg in its default repositories. If you want to install it you'll have to add a new repo first.

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.

November 10, 2014

1. Create your gem:

Here is the most modern approach to gem crafting:

bundle gem gemname
cd gemname

edit your_gem.gemspec and add description, summary, required gems and optional website. Add required gems for development such as rspec, rails or minitest to the Gemfile.

2. Add testing framework:

RSpec:
rspec --init
touch spec/your_gem_spec.rb
Minitest:
# Rakefile
