WWW-Analytics-MultiTouch is a tool and a Perl library for multi-touch Web analytics. Unlike typical last-session attribution Web analytics, multi-touch gives insight into all of the various marketing channels to which a visitor is exposed before finally making the decision to buy.
Math-Random-Xorshift is a Perl module that contains a straightforward implementation of the Xorshift PRNG algorithm proposed by G. Marsaglia in 2003. The algorithm is extremely fast and passes the Diehard test, though it is not reliable enough statistically. This module is useful for games and similar applications.
TCB::Conference is a DBIx::Frame object written to track external registrants for the 2003 TCB Summer School. It provides external forms for registrants to apply with; internal scripts, for local users to track who has applied and what their status is; and administrative scripts for adding, modifying, or deleting this information. It was used for a single conference, but may be useful again.
XML::XPath locates nodes in XML documents using the XPath syntax. It aims to fully comply with the specification while trying to be as quick as possible. It is also extensible for XSLT and XPointer. It is entirely Perl-based to minimize dependencies and ease installation, and does not use XML::DOM, although it can build DOM trees using a SAX event driver.
Hook::LexWrap allows you to install a pre- or post-wrapper (or both) around an existing subroutine. Unlike other modules that provide this capacity (e.g. Hook::PreAndPost and Hook::WrapSub), Hook::LexWrap implements wrappers in such a way that the standard 'caller' function works correctly within the wrapped subroutine.
