From deep in the network layer comes Michal Zalewski with news of a novel way to greatly extend your storage capacity: Juggling with packets. Like a juggler with more objects than hands, you can in theory send data out into the internet so that it eventually comes back to you, and store data out in orbit. With disk prices where they are, I’m not sure why you’d want to, but it’s a cool idea anyway.
Michal is also one of the authors of p0f, which is a mysterious network-level app that can identify remote systems based on passive observation of TCP packets. Poking around on his page reveals many other strange pursuits. Dark arts indeed.
