KK, Jenkins and the Triumph of Technology
Kohsuke Kawaguchi is the most brilliant developer and creator I have gotten the chance to work with (we work together at CloudBees). I just got back from the Jenkins Users Conference , where 450 people from around the world (literally) attended and another 500+ watched via live video stream. In his keynote, KK reviewed his concerns with having created Jenkins. (It is the defacto "Continuous Integration Server". Many, many companies use it to "build, test and deploy" their software - meaning it winds up being the glue that glues the pieces together of many of the applications people use today like Yahoo, Netflix, EBay, Amazon Kindle, cell phones, etc. Not to mention big companies like Cisco, AMEX, Macy's, Nordstrom and literally tens of thousands of others.) To "build, test and deploy" all of these applications, he estimates it takes 3 Facebook sized data centers running pretty much full time 24 hours a day, 7 days a week, 365 days a year
