The ROADS software is a collection of tools which can be used in building on-line catalogues of Internet resources. Key features are simple text based resource description format, World-Wide Web forms based resource description editor, WWW and WHOIS++ based search capability, automatic generation of customised views of the catalogue, automatic generation of listings of recently added resources, dynamic browsing of resources in particular subject categories, highly customizable HTML output, distributed indexing and searching across multiple WHOIS++ servers using the Common Indexing Protocol and more.
TkMan is a graphical, hypertext manual page and Texinfo browser for UNIX. TkMan boasts hypertext links, (optional) outline view of man pages, high quality display and superior navigational interface to Texinfo documents, a novel information visualization mechanism called Notemarks, full text search among man pages and Texinfo, incremental and regular expression search within pages, robust yellow highlight annotations, and more.
Elvis is a clone of vi/ex, the standard UNIX editor. Elvis supports nearly all of the vi/ex commands, in both visual mode and ex mode. Elvis adds support for multiple files, multiple windows, a variety of display modes including "hex" and "html", on-line help, WYSIWYG printing, and other miscellaneous extensions.
Obsidian is an extensible virtual world system with a fullblown multiplayer client-server architecture. It is not a VRML2 world system, though there are plans to include VRML2 as a world data format. Note that active development on this system stopped a while ago, though the code is still available for the curious. The code may not even compile on current Linux or Irix systems.
Spong is a simple system-monitoring package. It features client-based monitoring (CPU, disk, processes, logs, etc.), monitoring of network services, grouping of hosts (routers, servers, workstations, and PCs), host-specific contact and downtime information, configuration on a client-by-client basis, results displayed via the Web, history of problems, messaging (via email or pager) when problems occur, and verbose information to help diagnosis problems. It communicates via simple TCP-based messages, and is written in Perl.
Perl is a high-level, general-purpose programming language that makes easy things easy and hard things possible. It is optimized for scanning arbitrary text files and system administration. It has built-in extended regular expression matching and replacement, a dataflow mechanism to improve security with setuid scripts and is extensible via modules that can interface to C libraries.
LPRng is the Next Generation in LPR software. It supports the standard bsd lpr commands and also supports an System V interface. Other features include lightweight lpr, lpc, and lprm programs, dynamic redirection of print queues, automatic job holding, highly verbose diagnostics, multiple printers serving a single queue, client programs do not need to run SUID root, greatly enhanced security checks and a greatly improved permission and authorization mechanism. The default configuration provides a simple BSD LPR interface, but there are options to modify a wide variety of operational facilities. The companion IFHP print filter can interface to a wide variety of printers, from the latest network based high speed to vintage legacy printers.
perldbgui is a GUI for the standard Perl debugger. The GUI consists of two windows: one is a console window that's just like the regular perl debugger, the other is a source window that displays the executing source code. From the source window you can load other files, execute commonly used commands with buttons at the bottom, and execute almost any debugger command with keyboard shortcuts.
Data::Locations is a virtual file manager which allows you to write and read data (text and binary) to and from virtual files (think of bubbles). Moreover, this manager allows you to (recursively) define "magic" insertion points in these virtual files (bubbles inside other bubbles) which can be filled in (inflated) later (through a "straw", i.e., the object's reference), at any convenient time and in any order you like. Since this software acts purely in memory, there is no slowing down through costly file input/output (i.e., no temporary files).
