2. "In software development, Git /ɡɪt/ is a distributed
   revision control and source code management
   (SCM) system with an emphasis on speed. Git was
   initially designed and developed by Linus Torvalds
   for Linux kernel development in 2005. Every Git
   working directory is a full-fledged repository with
   complete history and full version tracking
   capabilities, not dependent on network access or a
   central server."

   constantly take pictures of you: while you're eating, while you're
   walking, while you're sleeping; tracking down your every move. At
   first it's a little difficult to get used to it, but the day you really need
   to know what you were wearing at your third cousin's best friend's
   brother's 17th birthday party, those photos will come in handy.)
