Last year Golan Levin's son decided to build a car. Aside from the minor inconvenience of being 4 years old, the younger Levin faced an engineering challenge. His Tinkertoys, which he wanted to use for the vehicle's frame, wouldn't attach to his K'Nex, the pieces he wanted to use for the wheels. It took his father, an artist, hacker and professor at Carnegie Mellon, a year to solve that problem. In the process he cracked open a much larger one: In an age when anyone can share, download and create not just digital files but also physical things, thanks to the proliferation of cheap 3-D printers, are companies at risk of losing control of the objects they sell?

The aim of the Askemos project is to enable reliable and justiciable data processing, with the goal of producing "Software that can last 200 years." The first implementations of an Askemos peer can be obtained from ball.askemos.org. The Askemos web site itself is served from the Askemos/BALL development network. Follow here for more details. Note that Askemos concerns the abstract specification exclusively; including data formats, protocols, service interfaces etc. - not the actual implementations. Askemos combines incorruptible privilege delegation and non-repudiable replication of communicating processes into a trustworthy network. Physical machines under control of their operators execute applications processes under permanent multilateral audit. The network's honest majority of hosts provides users with exclusive control, and thus real ownership of processes. Askemos models a kind of "virtual constitutional state" where physical hosts bear witness to the interactions of virtual agents (akin to citizens). Self verifying identifiers can confirm that original documents have not beentampered with. The real potential for using Askemos is for identity and time stamp services, informationmanagement in public administration and libraries attaching metadata and archives, with the goal of establishing robust systems that can endure for centuries. German tax law, for instance, has storage requirements, which makes Askemos interesting even for private, individual use. Also Activist groups, non-profits and people who desire privacy and reliability in a chaotic and unpredictable world have much to gain from this software.

PopFab is a multi-tool for the 21st century. At its heart is a computer-controlled motion platform and a means of attaching various toolheads. These enable PopFab to make objects from a digital plan in a variety of ways: current capabilities include 3D printing (as you are about to see), milling, vinyl cutting, and drawing - with more on the way. PopFab has traveled the world as a carry-on item of luggage to Saudi Arabia and Germany, and within the USA to Aspen in Colorado. We hope that this is only the beginning.
