FFmpeg has been removed from Ubuntu 14.04 and was replaced by Libav. This decision has been reversed so that FFmpeg is available now in Ubuntu 15.04 again, but there is still no official package for 14.04. In this tutorial, I will show you how to install FFmpeg from mc3man ppa. Add the mc3man ppa:

sudo add-apt-repository ppa:mc3man/trusty-media
And confirm the following message by pressing <enter>:

Also note that with apt-get a sudo apt-get dist-upgrade is needed for initial setup & with some package upgrades
More info: https://launchpad.net/~mc3man/+archive/ubuntu/trusty-media
Press [ENTER] to continue or ctrl-c to cancel adding it
Update the package list.

Rails changed the default behavior for WEBrick somewhere around version 4. Instead of binding to 0.0.0.0, it will now default to localhost.

This makes life difficult when you're running Rails inside a VM like Vagrant, mostly because it won't work. ;)

Fortunately, you can force Rails back into the old universal address with the following snippet

# config/boot.rb

# ... end of existing file

synth

class AddFieldsToDelayedJobs < ActiveRecord::Migration
  def change
    add_column :delayed_jobs, :signature, :string
    add_column :delayed_jobs, :args, :text
  end
end

# config/routes.rb
resources :documents do
  scope module: 'documents' do
    resources :versions do
      post :restore, on: :member
    end

    resource :lock
  end
end

Here's an example of how to embed a Gist on GitHub Pages:

{% gist 5555251 %}

All you need to do is copy and paste the Gist's ID from the URL (here 5555251), and add it to a gist tag surrounded by {% and %}.
