Last couple of weeks witnessed the passing of some very influential tech giants, Steve Jobs and Dennis Ritchie are the two I am more familiar with. People are talking about the significance of the products like movie Toy Story, iPod, iPhone, iPad that were produced under Steve’s leadership; Computer industries are again reminded of the great creations such as C programming language, Unix operation system, and many useful software tools for which Denis Ritchie was one of the brains behind.  These innovations already have and will continue to have lasting impact on how we develop our computing technologies and live our lives. All these also got me thinking of the ruins at Machu Picchu too. Although the creators, Incas people, are no longer there to show the place off to us, we cannot help but be impressed by how they came to select such a site, managed to build such a self-sustaining village, designed and built their houses, Sun-dial for season keeping, and terraces for agriculture.  After some serious thoughts, I believe that useful innovations and striving for perfection should be the two most critical elements for us to build technologies and products that will have long-lasting impact.
