The objective of the NIST Web Metrics Testbed is to explore the feasibility of a range of tools and techniques that support rapid, remote, and automated testing and evaluation of website usability. There are currently six components: 1. Web Static Analyzer Tool (WebSAT): checks web page HTML against typical usability guidelines. 2. Web Category Analysis Tool (WebCAT): lets the usability engineer construct and conduct a web category analysis (card-sorting). 3. Web Variable Instrumenter Program (WebVIP): instruments a website to capture a log of user interaction. 4. Framework for Logging Usability Data (FLUD): a file format and parser for representation of user interaction logs (such as those captured by WebVIP). 5. VisVIP Tool: produces a 3D visualization of user navigation paths through a website, based on FLUD data. 6. TreeDec: adds navigation aids to the pages of a website.
Data Architect is a database modelling tool capable of building ERD diagrams, reverse engineering of existing databases, and creation and modification of databases. It includes a powerful SQL editor and support for various database backends through ODBC. It is available both on Windows and Linux.
DXSpider is a Ham Radio program that connects to other similar programs by radio or the internet and provides a real-time information service to Ham Radio operators rather like IRC. It is designed to become a complete replacement for the original DOS implementation written by Dick Newell AK1A.
KeyKit is a multi-tasking interpreted programming language (inspired by awk) designed exclusively for realtime and algorithmic MIDI manipulation. KeyKit's GUI provides several dozen tools for algorithmic music experimentation, including a multi-track sequencer and drum pattern editor. The GUI and all tools are completely written in the KeyKit language itself. This allows users to add new tools and operations to the existing tools, even while the system is running. Complete C source code and precompiled executables for Windows and Linux are provided.
OpenVerse is similar to other graphical chat systems like Excite Chat and Microsoft Chat, with the main differences being that OpenVerse is open source software, has no advertisements, and also runs on a variety of systems including Windows, Unix, Macintosh, and just about anything else for which you can find a copy of TCL/TK.
Tkinter is Python's de facto standard GUI (Graphical User Interface) package. It is a thin object-oriented layer on top of Tcl/Tk. To use Tkinter, you don't need to write Tcl code, but you will need to consult the Tk documentation and occasionally the Tcl documentation (since Tk's low-level event handling mechanism is considered part of Tcl).
