Linux Rocket
Another from Wired Online. Amateur rocket enthusiasts are using the Linux OS to help give their rockets the smarts they need to fly. While the rockets are in no way professional, capable of carrying payload or instruments into space, they do serve to exemplify what off the shelf equipment can do. There is actually hope that these guys can get their rockets into orbit - that would be a feat for an amateur group. Kinda makes me want to start playing with rockets again!
The first chef
First came fire ... and then, as the camera shifts to the soon to be late-village idiot, you're left wondering -- just what was going through that mind -- and food is put on the fire, for the first time, and cooking is accidentally discovered by humanity. The first chef is ridiculed by grunts, then the local thug tries a sample of the burnt carcass, and soon, everybody gets queued at the McDonalds drive-thru. What happened? Richard Wrangham of Harvard believes there's more to cooking than evolutionary history would have you believe. Wrangham points out that there is no way homo sapiens could survive on just raw food. Raw food just doesn't give up calories as easily as cooked food -- and raw food makes the digestive system expend more energy to get at those calories. Cooking on the other hand breaks complex molecules down, allowing the digestive system to make easy work of them -- and cooking also softens food, allowing the body to get to the calories with less effort...
