Programming a Parrot AR.Drone 2.0 with Python - The Easy Way
The PS-Drone-API is a full featured SDK, written in and for Python, for Parrot's AR.Drone 2.0. It was designed to be easy to learn, but it offers the full set of the possibilities of the AR.Drone 2.0, including Sensor-Data (aka NavData), Configuration and full Video-support. The video function is not restricted to mere viewing, it is also possible to analyze video images data using OpenCV2. Obviously, the PS-Drone is perfect for teaching purposes; however, even the requirements for professional purposes can be satisfied. PS-Drone comes with a tutorial, explaining its most important commands and the drone's most important sensor values. The examples are easy to understand for people with little programming experience. A full list of commands and a description of all sensor data is available in a detailed documentation. It took several months to create PS-Drone, so it would be nice to get some donations for further development (e.g. Parrot's Bebop) and as a appreciation.

Extended C Library
Why Is libxc needed? There doesn't exist a library for ANSI C99 for common data containers, such as vectors, trees, etc. There also also doesn't exist a library for common functionality, such as error reporting/logging, string functions, configuration management (reading config files), etc... The programmer working in C doesn't have anything analogous to the Boost C++ library. The extended C library is intended to make some headway into providing this functionality. To ensure unrestricted usage the libxc project is provided under the very permissive BSD license. If you need a different license then please send me a request (lelanthran at gmail) and I'll do my best to satisfy your request. What's completed? As of writing, the following libraries have been written and tested: 1. Memory accounting/tracking 2. String operations 3. Vectors 4. Trees 5. Dictionary arrays 6. Configuration management See the wiki page for more information
