white_dune is a graphical VRML97/X3DV editor, simple NURBS/Superformula 3D modeller, animation tool, and VRML97/X3DV commandline compiler in development. VRML97 (Virtual Reality Modeling Language) is the ISO standard for displaying 3D data over the Web via browser plugins ("HTML for realtime 3D"). X3DV is the direct successor of VRML97. VRML97 and X3DV have support for animation, real-time interaction, and multimedia (images, movies, and sounds). white_dune can read, create, and display VRML97/X3DV files and let the user change the scenegraph/fields. It also has support for stereoscopic view via "quadbuffer"-capable stereo visuals, and support for 3D input devices like a joystick, spaceball, or magnetic tracker.
GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. The software aims to provide a unified and user friendly framework for editing structured documents with different types of content: text, mathematics, graphics, interactive content. TeXmacs can also be used as an interface to many external systems for computer algebra, numerical analysis, and statistics. New presentation styles can be written by the user and new features can be added to the editor using Scheme.
CodeWorker is a versatile parsing tool and a universal source code generator. It interprets a scripting language for producing reusable, tailor-made, evolving, and reliable IT systems with a high level of automation. The file formats to parse are described in an extended-BNF syntax. Template-based scripts drive the writing of patterns for generating code or text. The code generation knows how to preserve protected areas with hand-typed code and provides code expansion, source-to-source translation, and program transformation. It provides a native translation of CodeWorker's scripts in C++.
SWISH++ is a Unix-based file indexing and searching engine (typically used to index and search files on web sites). It was based on SWISH-E although SWISH++ is a complete rewrite. SWISH++ is at least 10 times faster and can handle much larger numbers of files. Additionally, it has unique features such as selective non-indexing, on-the-fly filters, user-selectable stemming, and more.
cw is a non-intrusive real-time ANSI color wrapper for common Unix-based commands. It is designed to simulate the environment of the commands being executed, so that if a person types 'du', 'df', 'ping', etc. in their shell it will automatically color the output in real-time according to a definition file containing the color format desired. It has support for wildcard match coloring, tokenized coloring, headers/footers, case scenario coloring, command-line- dependent definition coloring, and includes over 50 pre- made definition files.
prerex is an interactive (command-line) editor and a LaTeX macro support package that can be used to create very attractive and readable prerequisite charts. A graphical front-end for the editor also provides a prerex-enabled PDF viewer. A prerequisite chart is a network of course boxes linked by prerequisite and co-requisite arrows.
Rx4RDF is a set of technologies designed to make W3C's RDF less complex and easier to use. It includes RxPath, which enables one to use familar XML technologies like XPath, XSLT, and XUpdate to query, transform and update an RDF model, Raccoon, an application server that uses an RDF model for its data store and RxPath to translate arbitrary requests to RDF resources, and ZML and RxML, alternative text formats for XML and RDF that were designed to allow novices to write XML and RDF with (nearly) the same ease as a Wiki entry.
This C code module gives the Apache 1.3.x HTTP server the ability to correctly negotiate content types for XHTML documents. Currently these are sent as text/HTML for most Web sites. This gives maximum compatibility among older Web clients, but is not recommended practice according to the W3C.
4Suite XML is a Python-based toolkit for XML application development. It features a library of integrated tools for XML processing, implementing open technologies such as DOM, SAX, XPath, XSLT, XInclude, XPointer, XLink, XUpdate, RELAX NG, and XML/SGML Catalogs. The RDF and Repository components of 4Suite are separate packages that must be installed separately, on top of 4Suite XML.
