Here Shirky started talking about the importance of managing collaboration effectively. Large collaborative projects aren't, in fact, large collaborative projects according to Shirky. They're small collaborative projects with tight groups, that integrate very large amounts of small participatory effort. To put it another way, projects like Wikipedia and the Linux kernel may have thousands of contributors - but it's a small core of contributors who do the bulk of the work and integrate the work from others who only contribute a small amount. It's also important, says Shirky, that people cannot join the project too easily. Even given the presumption that all the participants have goodwill towards the project, he says that it shouldn't be too easy to change every aspect of a project. Some parts of the system should be easy to change, some parts should be hard.

Last Friday was my last day at the White House. As I begin my fellowship at Harvard University, I'd like to share my reflections on public service.  "On a bright February day, the previous morning's dusting of snow melting on the ground, I arrived at a White House that was, as the Washington Post put it, "stuck" in the "Dark Ages of technology." In their words, "If the Obama campaign represented a sleek, new iPhone kind of future, the first day of the Obama administration looked more like the rotary-dial past." As my team congratulated me on the new job, they handed me a stack of documents with $27 billion worth of technology projects that were years behind schedule and millions of dollars over budget. At the time, those documents were what passed for real-time updates on the performance of IT projects. My neighbor's ten year old could look up the latest stats of his favorite baseball player on his phone on the school bus, but I couldn't get an update on how we were spending billions of taxpayer dollars while at my desk in the White House. And at the same time, the President of the United States had to fight tooth and nail to simply get a blackberry.  These were symptoms of a much larger problem.

first-ever historical mapping and exploration of the full text contents of the English-language edition of Wikipedia, in time and space, with visualizations of modern history captured in under a day. Loading the entire English language edition of Wikipedia into SGI UV 2000, Mr. Leetaru was able to show how Wikipedia's view of the world unfolded over the past two centuries.

With MobileFrontend, we now have the ability to easily allow not only Wikipedia but our sister projects to have a mobile friendly view. No longer will it just be Wikipedia that has a mobile view.

"Do you mind if Microsoft drops a little future on you like a ton of bricks? This HoloDesk uses a half-silvered mirror and a Kinect sensor to "see" your hands in 3D space then project visible objects on and around them, allowing you to juggle virtual spheres, play with phones, and generally get all Minority Report up in this piece."
