My name is Khanh (not Khan) 🙂  I currently live in the San Francisco Bay Area and work for Cisco Systems.  Over the years I have been tinkering with various ideas and thoughts.  Some of them were published and some not.  So I created this blog to share my ideas with you and hope that this will be a platform that I can receive the comments and feedbacks from you to further develop the thoughts.  Thank you for reading 🙂
