Hailo is a fast and lightweight markov engine intended to replace AI::MegaHAL. It has a Mouse (or Moose) based core with pluggable storage, tokenizer, and engine backends. It is similar to MegaHAL in functionality. The main differences (with the default backends) are better scalability, drastically less memory usage, an improved tokenizer, and tidier output. With this distribution, you can create, modify, and query Hailo brains. To use Hailo in event-driven POE applications, you can use the POE::Component::Hailo wrapper. One example is POE::Component::IRC::Plugin::Hailo, which implements an IRC chat bot.
RTK (Ruckus Tool Kit) is a high-performance, Perl-based, dynamic, content-generation system. It provides a nearly transparent bridge between HTML-based code pages and traditional CGI-based systems. It has been designed to automatically take advantage of existing systems, such as basic CGI, Apache's mod_perl, FastCGI, and SpeedyCGI, but does not require such systems for high-performance optimization.
VoiceXML::Client is a library that provides Perl programs with the ability to act as a user agent that fetches Voice Extensible Markup Language (VoiceXML) documents, parses them, and then executes the instructions therein by playing prompts and collecting user DTMF input/voice recordings through a handle to some type of telephone or other device interface. VoiceXML::Client's focus is on the client side. The XML documents are generated by a distinct process of your choice, unrelated to the library.
Zero RRD Framework provides a central HTTP-based service for importing into standard RRD databases and for generating graphs. A lightweight, easily extendable agent for the data sources pushes updates with minimal resource consumption to the master service using HTTP. With the introduction of VMs for the service, it's easy to test-drive the application and even the architecture (connecting agents to the service in the VM).
