RTK is a toolkit to create reports from different sources (including but not limited to plain text files, XML, and SQL) in different formats (including but not limited to plain text files, HTML, OpenOffice Calc, and a graphical viewer) driven by a template file. This is an attempt to create a quality reporting tool similar to Crystal Reports or MS Access. The code is fully object oriented and designed to be highly scalable, small, and efficient.
Tao is a software package for sound synthesis using physical models. It provides a virtual acoustic material constructed from masses and springs, which can be used as the basis for building quite complex virtual musical instruments. It comes with a synthesis language for creating and playing instruments and a C++ API for those who would like to use it as an object library.
FFTExplorer is a GUI that performs spectral analysis on real-time data from a sound card or other source, and can analyze the spectra of various sound file types. It can display time-domain and frequency-domain data in a number of ways, and is an easy-to-use introduction to the topic of spectrum analysis. Beyond performing a fast Fourier transform on arbitrary data sources, it can also perform moving average noise reduction for the treatment of signals accompanied by noise. It contains a lengthy combination essay/help file on the various topics the program covers, some step-by-step examples using its own internal signal source, and a detailed example using an external source.
SignalGen is a GUI program that generates relatively low frequency signals with the use of a PC sound card. It is an entirely suitable replacement for a hardware signal generator if one doesn't require signals of a frequency higher than about 50 KHz. It creates any frequency between a fraction of one Hertz and an upper limit determined by your sound card's capabilities, typically about 50 KHz (accomplished by choosing the highest sampling frequency your sound card will provide, typically about 100 KHz). And, just like a hardware audio generator, it will create sine, triangle, square and sawtooth waves. It has a built-in scope to allow you to monitor the generated waveform in real time. Its frequency accuracy is the same as your sound card, i.e. a small fraction of one Hertz.
SlideProjector is a GUI program meant to prepare and display electronic slide shows. It relies on computer graphic files as its source of programming material, and can be made to show the images in many different ways. It retains user choices and its created slide shows as plain text files, allowing interfacing with other programs that handle image lists. It allows the user to examine and manipulate directories of graphic images, creates a plain-text "show" file containing the images chosen by the user, and then displays that show. It is compatible with the commands issued by common multimedia projectors.
NetworkControl is a utility to control and monitor network interfaces, including wireless ones (for which you see a signal strength meter, as shown). It addresses a conspicuous lack in most Linux distributions: most tend to be short on easy-to-use network utilities, even something as trivial as a robust, informative way to log on and off a dialup connection. It also provides the connection IP, configuration, and statistics (gleaned from "ifconfig" and updated every second), and provides graphical signal levels for wireless interfaces, handy for evaluating a system of wireless devices. It allows you to see network activity at a glance and lets you control your network interfaces in a fast, convenient way. It is designed to be informative and easy to use.
