Qt is a comprehensive, object-oriented development framework that enables development of high-performance, cross-platform rich-client and server-side applications. When you implement a program with Qt, you can run it on the X Window System (Unix/X11), Apple Mac OS X, and Microsoft Windows NT/9x/2000/XP by simply compiling the source code for the platform you want. Qt is the basis for the KDE desktop environment, and is also used in numerous commercial applications such as Google Earth, Skype for Linux, and Adobe Photoshop Elements.

The Open Real-Time Ethernet (ORTE) is an implementation of the Real-Time Publish-Subscribe (RTPS) communication protocol. RTPS is a new application layer protocol targeted to real-time communication areas, and is built on the top of standard UDP stack. Since there are many TCP/IP stack implementations under many operating systems, and RTPS does not have any other special hardware or software requirements, it should be easily ported to many target platforms. Because it uses only UDP, it retains control of timing and reliability.
Super Grub Disk is a bootable floppy or CDROM that is oriented towards system rescue, specifically for repairing the booting process. Super Grub Disk is simply a Grub Disk with a lot of useful menus.

GNU libmicrohttpd is a small C library for embedding HTTP server functionality into other applications. It is reentrant, fast, supports HTTP 1.1, and permits listening on multiple ports. The API is simple and still powerful enough to allow programmers to use the entire HTTP feature set. SSL/TLS support is available as an option.
As a plugin API, Frei0r's main emphasis is on simplicity, to round up the most common video effects into simple filters, sources, and mixers that can be controlled by parameters. Frei0r plugins can be shared by many host applications, avoiding duplicate efforts by different projects. Frei0r is not meant as a competing standard to more ambitious efforts trying to satisfy the needs of many different applications and more complex effects, as it doesn't provides things like an extensive parameter mechanism or event handling.
