OpenSCAD – The Programmers Solid 3D CAD Modeller – [via]
OpenSCAD is a software for creating solid 3D CAD objects. It is free software and available for Linux/UNIX, MS Windows and Mac OS X.
Unlike most free software for creating 3D models (such as the famous application Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. Thus it might be the application you are looking for when you are planning to create 3D models of machine parts but pretty sure is not what you are looking for when you are more interested in creating computer-animated movies.
OpenSCAD is not an interactive modeller. Instead it is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file (see examples below). This gives you (the designer) full control over the modelling process and enables you to easily change any step in the modelling process or make designes that are defined by configurable parameters.
OpenSCAD provides two main modelling techniques: First there is constructive solid geometry (aka CSG) and second there is extrusion of 2D outlines. As data exchange format format for this 2D outlines Autocad DXF files are used. In addition to 2D paths for extrusion it is also possible to read design parametes from DXF files. Besides DXF files OpenSCAD can read and create 3D models in the STL and OFF file formats.

Have your first 3D project ready for printing in minutes. Tinkercad is a new and faster way of creating designs for your 3D printer. With the help of the latest web technology you can now use a solid modeling CAD directly in your browser. The user interface is designed to get things done fast and to be quick to learn. With only three basic tools you can create a wide range of useful things. Once your project is ready simply download the STL file and start your 3D print.

Next-generation laptops won’t have hard drives. Instead, they’ll use flash memory—the same found in camera memory cards and iPhones. Flash-based drives are thinner, faster and nearly indestructible.
Like a traditional hard drive, a flash-based drive stores information in the computer-readable language of 0s and 1s. But instead of writing data by flipping magnetic poles on a spinning disk, flash memory just shuttles electrons around on a stamp-size microchip.
