Visualizing nanotechnology in 3D with open source software

The new open source project tomviz is helping the 3D visualization of nanotechnology.

Modern computers are built with nanotechnology. A processor contains billions of transistors, each around 14 nanometers. A single bit of information on a hard disc drive is confined to a 10 nanometer domain spinning on a disc 75 miles per hour. The accelerometers in our smartphones contain nano-springs that measure gravitational forces to determine orientation.

Back to school with GRASS GIS

When we started talking about hosting a 'back to school' week at Opensource.com, I decided to take that quite literally, and went back to NC State University earlier this month to attend the inaugural Geospatial Forum at the Center for Geospatial Anaytics. Geospatial analytics and GIS (geospatial information science) is a huge field, with a number of open source tools for research and teaching available, and I wanted to learn more about how these tools are being used in the real world.
