To obtain certain lighting effects, you sometimes need to attach things to your flash head, such as gel filters or bounce cards. Normally, this involves fussing around trying to strap things down with a rubber band or opting to gum up your equipment with sticky-backed velcro or tape. Instead you can create a cheap speed […]
Hadoop is a Java-based distributed application and storage framework that’s designed to run on thousands of commodity machines. You can think of it as an open source approximation of Google’s search infrastructure. Yahoo!, in fact, runs many components of its search and ad products on Hadoop, and it’s not too surprising that they are a […]

Gene Hacker created a 3D printer out of LEGO. It’s like a lo-rez reprap that operates in polar coordinates instead of the more familiar cartesian system. This is still very alpha and his demos show some promising 3D blobs of frosting. With that in mind, however, most of the basic functionality of a rapid fabrication […]

By 2001, he started placing orders for technical documentation and had chosen his target machine, a Block I Apollo Guidance Computer.
