How to move to a fork after cloning
So you've cloned somebody's repo from github, but now you want to fork it and contribute back. Never fear!
Technically, when you fork "origin" should be your fork and "upstream" should be the project you forked; however, if you're willing to break this convention then it's easy.
* Off the top of my head *
1. Fork their repo on Github
2. In your local, add a new remote to your fork; then fetch it, and push your changes up to it
git remote add my-fork git@github...my-fork.git

What to do when your ubuntu distro is End-of-Life

Let's say you're using Ubuntu 13.04 (Raring Ringtail, released in April 2013) and it just went End-of-Life on you, because it's supported for only 6 months, and the deprecated packages are taken down after 12 months.

You'll probably figure this out the hard way. When you run sudo apt-get update, it will eventually report these errors:

Ign http://archive.ubuntu.com raring-updates/universe Sources/DiffIndex
Err http://security.ubuntu.com raring-security/main Sources
  404  Not Found [IP: 91.189.91.15 80]
