DIY Laptop 178

Posted by Hemos on Monday March 05, 2007 @10:10AM from the from-the-ground-up dept.

Brietech writes "Ever felt like building your own laptop from (almost literally) scratch? This is a microcontroller-based "laptop" built from the ground up from a handful of chips and other hardware found lying around. It runs a self-hosted development environment, allowing the user to write and edit programs in "Chris++" on the machine, and then compile and run them. The carpentry looks like it could use some work, but it's a neat project!"

Computer Forensics to Help Solve Pioneer Mystery 113

Posted by Hemos on Monday March 05, 2007 @09:37AM from the deconstructing-the-past dept.

Matthew Sparkes writes "Launched 35 years ago on Friday, Pioneer 10 was the first spacecraft to reach the outer Solar System and return pictures of Jupiter, closely followed by Pioneer 11. However, the twin Pioneer spacecraft drifted off course (see number 8) by hundreds of thousands of kilometres during their three-decade mission, and NASA eventually lost contact with them. An international team of scientists, including many amatuer hobbyists, are re-analysing the tracking and telemetry data in the hope of discovering the reason."

This finding about leopard spots has nothing to do with Turing machines. It is less well known among computer scientists that Turing has also done fundamental research in the field of chemical pattern formation (http://en.wikipedia.org/wiki/Alan_Turing#Pattern_ formation_and_mathematical_biology). BTW this is no news. It is well known that spotted patterns can be reproduced by reaction diffusion equations. These mechanisms have been thoroughly studied using computer simulations since the '80s. A really interesting result would be to find the actual chemical processes in the leopard that produce the spots, but no experimental evidence yet ...
