netscript is a portable/multi-platform, lightweight TCP/UDP socket scripting system. It is intended to automate situations, built on a word-to-word ruleset response system. It includes wildcard support, character replacement, random replacement, argument inclusion, server timeout, initial send, display altering, multiple character dump formats, telnet protocol support, logging, program to socket dumping, executable ruleset support, reverse binding, module support, data truncation, data formatting, permission options, virtual hosting support, history storage, dynamic storage variables, directory placement, character omitting, timed rules, background support, syslog support, routing support, socket options, interactive mode, and graphical user interface support.
Checky is a document validation and analysis extension for Firefox, Mozilla, and Netscape. It provides an easy-to-use interface to many free and commercial online validation and analysis services. It allows the user to validate, analyze, view, and inspect documents containing HTML, XHTML, CSS, RDF, RSS, XML, P3P, hyperlinks, metadata, and many more. It can check Section 508 and WAI compliance of documents with many helpful services. It can help in the design, development, and maintenance of accessible documents for a semantic web.
CRM114 is a Controllable Regex Mutilator and Smart Filter, designed for easy creation of filters for things like incoming email redirection, spam filtering, system logs, or monitoring processes. Filtering rules can be either hard-coded (such as regexes), soft-coded (calculated at runtime or read from an external file or process), or learned dynamically by phrase matching (as in Bayesian filtering, Markovian matching, Winnowing, or Hyperspatial classification). This makes it possible to create very accurate filters with very little actual work. Accuracies over 99.9% are achievable.
NSC is a set of utilities for easy administration of DNS servers. You write very simple configuration files and NSC automatically generates zone files, reverse zone files, and configuration for the BIND. Among other things, it also supports classless reverse delegations and IPv6 addressing. NSC is written in POSIX shell and GNU M4, and it should run on all systems where these two languages are available. Generation of DNS daemon config files is currently limited to BIND 8 or 9, but it's very easy to add your own config file generators for other daemons.
Cassandra is a scientific data viewer based on VTK. Cassandra provides dynamic interaction with the VTK pipeline and enables the user to load plug-ins dynamically in order to perform specific tasks in data manipulation and visualisation. Cassandra is open and modular, and can easily be extended to new filters through a set of dynamically loadable plug-ins. A plug-in template is provided to help users to develop and share their own plug-ins. This approach allows users to perform complex filtering without any specific knowledge of VTK or C++.
Onyx is a powerful stack-based, multi-threaded, interpreted, general purpose programming language similar to PostScript and Forth. It can be embedded as an extension language into other applications, and was designed to have a small memory footprint. It is among the smallest embeddable interpreters available.
