        What do Google and China have in common?




            命運
      We both want to control our technological destiny.
        Google as a company, China as a country.
            Open Source makes that possible.

How does Google use Open Source?

 As Infrastructure
 • The Linux kernel
 • SSH, and other system management tools
 • The Languages and compilers that we use.
 • Engineers and others running Linux (Goobuntu)
 As building blocks
 • Our software uses many hundreds of libraries.




                                                   11
Why does Google use Open Source?

 Control and Ownership
 • Maintain our independence from external software
   companies
 Adaptability and Flexibility
 • We can drill down to repair and enhance our services
 • If we want to do something out of the ordinary, we can do
   so without showing our hand
 Roots
 • Appeals to the Google ethic

   Every time you use Google you are using Open Source


                                                               12
