Asymptote is a powerful descriptive 2D and 3D vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. It provides for figures the same high-quality level of typesetting that LaTeX does for scientific text. Asymptote is a programming language as opposed to just a graphics program. It can exploit the best features of script (command-driven) and graphical user interface (GUI) methods. High-level graphics commands are implemented in the language itself, allowing them to be easily tailored to specific applications.
Beonex Communicator is Mozilla polished for end users. It contains Navigator, Mailnews, Composer, and ChatZilla. Navigator has support for key web standards and a convenient interface. For example, it eases searching the Internet, similar to Apple's Sherlock on Macintosh. The Bookmark Manager can deal with huge collections of bookmarks and allows you to overview and sort them while you are surfing. If you want, you can track the latest headlines or webcams using the Sidebar. The Mailnews client supports multiple IMAP, POP3 and/or news accounts for each user, so you can download and manage all your email from various accounts in one place and store them on your computer or the server. Beonex puts a strong emphasis on security, privacy, and netiquette, to protect the private or confidential information on your computer and to encourage fairness.
Ellogon is a multi-lingual, cross-platform, general-purpose language engineering environment, developed in order to aid both researchers who are doing research in computational linguistics, as well as companies who produce and deliver language engineering systems. As a language engineering platform, it offers an extensive set of facilities, including tools for processing and visualising textual/HTML/XML data and associated linguistic information, support for lexical resources (like creating and embedding lexicons), tools for creating annotated corpora, accessing databases, comparing annotated data, or transforming linguistic information into vectors for use with various machine learning algorithms.
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.
HTML Include solves the problem that the Hypertext Markup Language doesn't know a command for including other files into a source file. It uses specially styled comments to refer to other files, which will be inserted at this position. Unlike to the well known Server Side Include mechanism, this tool pre-processes the HTML files, resulting in files that have all referenced source files directly embedded. Thus it does not depend on any Web-server for correct appearance. As a bonus, HTML Include also writes the current date to the "last modification" line and brower meta, which you usually forget (or do not bother) to update.
HTMLDOC converts HTML files and Web pages into indexed HTML, PostScript, and PDF files suitable for online viewing and printing. It can be used as a standalone GUI application, in a batch document processing environment, as a Web-based report generation application, or in embedded environments to support printing of HTML content. It runs on all Unix platforms as well as Mac OS X and Windows 2000 and higher.
