XED is a text editor for XML document instances. It is designed to support hand-authoring of small-to-medium-sized XML documents, and is optimized for keyboard input. It works very hard to ensure that you cannot produce a badly-formed document. Although it does not validate, the results of offline validation can be accessed, and it does read DTDs and keep track of your document structure, and provides context-based accelerators to make element and attribute entry fast and easy.
The PLLProgram is a tool to design and analyse charge-pump phase-locked loops. Loop filters up to the 4th order can be designed. The phase noise with file based VCO data can be calculated, and the transient response can be plotted. Nonlinearities of VCO gain and charge pump currents are taken into account. The program is suited for integer, fractional N, and sigma delta PLLs.
LibUFO is a C++ core library for graphical user interfaces (GUI). It is mainly used as OpenGL GUI toolkit. Most standard components (such as buttons, labels, menus, and internal frames) are included. It is customizable via look-and-feel and themes. There are three built-in video drivers (respectively using GLX/X11, WGL/Win32, and LibSDL) which are selected and loaded at run-time. You may also create your own backend or use a dummy driver to include libUFO widgets into an already existing OpenGL context.
