Racket (formerly PLT Scheme) is a programming language suitable for implementation tasks ranging from scripting to application development, including GUIs, Web services, etc. It includes the DrRacket programming environment, a virtual machine with a just-in-time compiler, tools for creating stand-alone executables, the Racket Web server, extensive libraries, documentation for both beginners and experts, and more. It supports the creation of new programming languages through a rich, expressive syntax system. Example languages include Typed Racket, ACL2, FrTime, and Lazy Racket.
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.
Ziproxy is a high-performance forwarding (non-caching) HTTP proxy that gzips text and HTML files, and reduces the size of images by converting them to lower quality JPEGs or JPEG 2000. It is intended to increase the speed for low-speed Internet connections (mobile, dial-up, other). It's suitable for both home and professional usage. Ziproxy is fully configurable and also features transparent proxy mode, HTML/JS/CSS optimization, operation in daemon mode, a detailed access log with compression statistics, basic authentication, and more.
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++.
Enblend is a postprocessing tool for creating panoramic images. After you align image features using a program like Hugin, there are often photometric problems that lead to ugly seams in the final composite. Enblend blends away these seams using a multiresolution spline. This technique gives good results on both low spatial frequency objects (sky and clouds) and high spatial frequency objects (trees and houses).
ivata groupware is a groupware/intranet portal system based around J2EE standards. It provides an enterprise-ready solution. It is a great tool to enable teams to find contacts in team and private address books, to share documents, to post articles and notes, to comment on articles, to receive notifications via email, to plan meetings and other events in the calendar, and to access email via the Web.
