Arduino is an open embedded hardware and software platform designed for rapid creativity. It's both a great introduction to embedded programming and a fast track to building all kinds of cool devices like animatronics, robots, fabulous blinky things, animated clothing, games, your own little fabs... you can build what you imagine. Follow along as we learn both embedded programming and basic electronics.

"When I think of open source, Linux is the core," says William Eshagh, a technologist working on Open Government and the Nebula Cloud Computing Platform out of the NASA Ames Research Center. Eshagh recently announced the launch of code.nasa.gov, a new NASA website intended to help the organization unify and expand its open source activities. Recently I spoke with Eshagh and his colleague, Sean Herron, a technology strategist at NASA, about the new site and the roles Linux and open source play at the organization.
