Rute (Rute Users Tutorial and Exposition) is a book on GNU/Linux that aims to be the definitive guide for new users as well as sufficing as training course material, covering both the RHCE and LPI requirements. It covers essential theory to UNIX as well as giving practical tutorials on all fundamental aspects of Unix administration, from basic commands, the theory of TCP/IP, the Linux filesystem, through to configuration of mail, DNS, and other servers, through hardware configuration and package management. It is not Unix-specific but tends to give examples suited to Debian and RedHat-like systems. Rute comes in HTML and PDF formats.
Multivalent Browser is a utility that natively views scanned paper, PDF, HTML, UNIX manual pages, and TeX DVI. The browser supports in situ annotations such as hyperlinks, highlights, notes, and executable copy editor markup on any of these formats. It boasts advanced features such as lenses and robust locations. For developers, Multivalent has an API for extensions, and the document viewers can be embedded in Java Swing-based applications.
AsciiDoc is a text document format for writing short documents, articles, books, and UNIX man pages. AsciiDoc files can be translated to HTML and DocBook markups using the asciidoc(1) command. AsciiDoc is highly configurable: both the AsciiDoc source file syntax and the backend output markups (which can be almost any type of SGML/XML markup) can be customized and extended by the user.
xslui is an XSLT applet to display Web pages with a modularized XML file in Web browsers. This applet can design page layout by arranging square blocks called "areas". Thus it is very easy to display layouts like horizontal columns. This layout feature can also separate descriptions of an area's arrangement and contents, even in different files. This feature provides Web pages with modularization and sharing of their parts. In addition, xslui has data operating elements with the xsldo library, which can operate on XML data in the same or other XML files as the display data. This feature provides separation of views and data.
Ajaqs is a Web application that organizes FAQs on a per-project basis. The UI is templatized, the content is internationalized, and the styles are highly configurable. Secure login is provided via webapp security constraints. The backend uses an O-R mapping tool to achieve independence of database-specific queries. RSS feeds provide subscribers continuous updates on a per-project or per-FAQ basis. FAQs are dynamically served up as HTML pages, and can optionally be streamed to clients as PDF content.
