Google, the search engine to end all search engines.
Developed at StanfordUniversity. (An ex-WaikatoUniversity student from the Digital Libraries lab used to work for Google.)
Probably the world's biggest Linux Cluster. (Currently processes over 150 million queries a day, searching a multi-terabyte web index for every query with an average response time of less than a quarter of a second, with near-100% uptime.)
