Linus Torvalds transformed technology twice — first with the Linux kernel, which helps power the Internet, and again with Git, the source code management system used by developers worldwide. In a rare interview with TED Curator Chris Anderson, Torvalds discusses with remarkable openness the personality traits that prompted his unique philosophy of work, engineering and life. "I am not a visionary, I'm an engineer," Torvalds says. "I'm perfectly happy with all the people who are walking around and just staring at the clouds ... but I’m looking at the ground, and I want to fix the pothole that's right in front of me before I fall in."

Jimmy Wales The birth of Wikipedia

Jennifer Pahlka Coding a better government
Can government be run like the Internet, permissionless and open? Coder and activist Jennifer Pahlka believes it can — and that apps, built quickly and cheaply, are a powerful new way to connect citizens to their governments — and their neighbors.
Charles Leadbeater The era of open innovation
In this deceptively casual talk, Charles Leadbeater weaves a tight argument that innovation isn't just for professionals anymore. Passionate amateurs, using new tools, are creating products and paradigms that companies can't.
