John Kenneth Ousterhout is a professor of computer science at Stanford University. He founded Electric Cloud with John Graham-Cumming. Ousterhout was a professor of computer science at University of California, Berkeley where he created the Tcl scripting language and the Tk platform-independent widget toolkit, and proposed the idea of coscheduling. Ousterhout led the research group that designed the experimental Sprite operating system and the first log-structured file system. Ousterhout also led the team that developed the Magic VLSI computer-aided design (CAD) program.
Visual Molecular Dynamics (VMD) is a molecular modelling and visualization computer program. VMD is developed mainly as a tool to view and analyze the results of molecular dynamics simulations. It also includes tools for working with volumetric data, sequence data, and arbitrary graphics objects. Molecular scenes can be exported to external rendering tools such as POV-Ray, RenderMan, Tachyon, Virtual Reality Modeling Language (VRML), and many others. Users can run their own Tcl and Python scripts within VMD as it includes embedded Tcl and Python interpreters. VMD runs on Unix, Apple Mac macOS, and Microsoft Windows. VMD is available to non-commercial users under a distribution-specific license which permits both use of the program and modification of its source code, at no charge.
Eggdrop is a popular IRC bot and the oldest that is still being maintained.
GNU Ubiquitous Intelligent Language for Extensions is the preferred extension language system for the GNU Project and features an implementation of the programming language Scheme. Its first version was released in 1993. In addition to large parts of Scheme standards, Guile Scheme includes modularized extensions for many different programming tasks.
Shane's Chess Information Database (Scid) is a free and open source UNIX, Windows, Linux, and Mac application for viewing and maintaining large databases of chess games. It has features comparable to popular commercial chess software. Scid is written in Tcl/Tk and C++.
Tkinter is a Python binding to the Tk GUI toolkit. It is the standard Python interface to the Tk GUI toolkit, and is Python's de facto standard GUI. Tkinter is included with standard Linux, Microsoft Windows and macOS installs of Python.
Waikato Environment for Knowledge Analysis (Weka) is a collection of machine learning and data analysis free software licensed under the GNU General Public License. It was developed at the University of Waikato, New Zealand and is the companion software to the book "Data Mining: Practical Machine Learning Tools and Techniques".
ns is a name for a series of discrete event network simulators, specifically ns-1, ns-2, and ns-3. All are discrete-event computer network simulators, primarily used in research and teaching.
GNATS is the GNU project's issue-tracking software.
incr Tcl is a set of object-oriented extensions for the Tcl programming language. It is widely used among the Tcl community, and is generally regarded as industrial strength. Its name is a pun on "C++". Itcl implementations exist as both a package that may be dynamically loaded by a Tcl application, as well as an independent standalone language with its own interpreter.
Tk is a cross-platform widget toolkit that provides a library of basic elements of GUI widgets for building a graphical user interface (GUI) in many programming languages. It is free and open-source software released under a BSD-style software license.
Itk is a framework for building mega-widgets using the Incr Tcl object system. Mega-widgets are high-level widgets like a file browser or a tab notebook that act like ordinary Tk widgets but are constructed using Tk widgets as component parts, without having to write C code. In effect, a mega-widget looks and acts exactly like a Tk widget, but is considerably easier to implement.
wish is a Tcl interpreter extended with Tk commands, available for Unix-like operating systems supporting the X Window System, as well as macOS, Microsoft Windows, and Android. It provides developers the ability to create GUI widgets using the Tk toolkit and the Tcl programming language.
Fossil is a software configuration management, bug tracking system and wiki software server for use in software development created by D. Richard Hipp.
Tkabber is a GPL instant messaging client for the XMPP protocol which uses the Tk toolkit for the GUI. It runs on anything to which Tcl/Tk is ported: almost any X-based system, Microsoft Windows, and Mac OS X.
tkWWW is an early, now discontinued web browser and WYSIWYG HTML editor written by Joseph Wang at MIT as part of Project Athena and the Globewide Network Academy project. The browser was based on the Tcl language and the Tk (toolkit) extension but did not achieve broad user-acceptance or market share, although it was included in many Linux distributions by default. Joseph Wang wanted tkWWW to become a replacement for r r n and to become a "swiss army knife" of networked computing.
Tcl is a high-level, general-purpose, interpreted, dynamic programming language. It was designed with the goal of being very simple but powerful. Tcl casts everything into the mold of a command, even programming constructs like variable assignment and procedure definition. Tcl supports multiple programming paradigms, including object-oriented, imperative, functional, and procedural styles.
In computer science and visualization, a canvas is a container that holds various drawing elements. It takes its name from the canvas used in visual arts. It is sometimes called a scene graph because it arranges the logical representation of a user interface or graphical scene. Some implementations also define the spatial representation and allow the user to interact with the elements via a graphical user interface.
rattleCAD — is a parametric 2D CAD software specific for bicycle design, in particular for design bicycle frame, developed by an Austrian cyclist and a programmer Manfred Rosenberger since 2008. Application is written in the Tcl programming language with the Tk-based GUI.
