GNU Radio is an open source Software Defined Radio (SDR) project that was started about ten years ago by Eric Blossom, an electrical engineer. The main idea which is behind this project, as its founder says, was to turn all the hardware problems into software problems, that is move the complexity of a radio equipment from the hardware level to the software one, and get the software as close to the antenna as possible.
BlueGriffon is a new WYSIWYG content editor for the World Wide Web. Powered by Gecko, the rendering engine of Firefox 4, it's a modern and robust solution to edit Web pages in conformance to the latest Web Standards.
It's free to download (current stable version is 1.0) and is available on Windows, Mac OS X and Linux.
BlueGriffon is available in English, French, Czech, German , Hebrew, Italian, Japanese, Simplified Chinese and Spanish.
BlueGriffon is an intuitive application that provides Web authors (beginners or more advanced) with a simple User Interface allowing to create attractive Web sites without requiring extensive technical knowledge about Web Standards.
Because Gecko lives inside BlueGriffon, the document you edit will look exactly the same in Firefox 4. Advanced users can always use the Source View to hard-code their page.
BlueGriffon is tri-licensed under the Mozilla Public License 1.1, the GNU General Public License Version 2 and the GNU Lesser General Public License Version 2.1.
