Basecamp is a web based project collaboration tool that makes it simple to communicate and collaborate on projects. Basecamp is built on the Ruby on Rails platform but provides a webservice API to many of the application functions. WebService::Basecamp is a Perl interface to the Basecamp web service API. For more information on Basecamp, visit the Basecamp website. http://www.basecamphq.com. This module does much of the heavy lifting for you when accessing the Basecamp API. Once initialising a WebService::Basecamp object you can access the API function via method calls. The module takes care of the creation and parsing of the XML (using XML::Simple) that relays the data across the web service, however there is an option to access the XML directly (see new()). The documentation for this module is based on the Basecamp API docs available at http://www.basecamphq.com/api. It is recommended you read the official docs to become familiar with the data reference.

Pd is a real-time graphical programming environment for audio and graphical processing. It resembles the Max/MSP system but is much simpler and more portable; also Pd has two features not (yet) showing up in Max/MSP: first, via Mark Dank's GEM package, Pd can be used for simultaneous computer animation and computer audio. Second, an experimental facility is provided for defining and accessing data structures. Unofficial web site: http://puredata.org/

This module is a wrapper around Aymerick Jehanne's libwbxml (or perhaps libwbxml2, I am not sure what the distinction is) library for handling Wireless Binary XML. You must install libwbxml2 prior to installing this module. The library can be found at http://libwbxml.aymerick.com/ (libwbxml2 itself requires the expat library to be installed.) The module defines two functions: xml_to_wbxml and wbxml_to_xml.

LMDB_File is a Perl wrapper around the OpenLDAP's LMDB (Lightning Memory-Mapped Database) C library. LMDB is an ultra-fast, ultra-compact key-value data store developed by Symas for the OpenLDAP Project. See http://symas.com/mdb/ for details. LMDB_File provides full access to the complete C API, a thin Perl wrapper with an Object-Oriented interface and a simple Perl's tie interface compatible with others DBMs.

"The Goo" helps you stick "Things" together in your working environment. Things include Perl modules, Perl scripts, log files, javascripts, configuration files, database tables, templates etc. The Goo records a "Trail" as you jump quickly from Thing to Thing in a simple, text-based console. It remembers how you associate Things in your environment. Accelerate your work by quickly traversing the Trail of associations between Things. http://thegoo.org/

This module implements the classic "Naive Bayes" machine learning algorithm. It is a well-studied probabilistic algorithm often used in automatic text categorization. Compared to other algorithms (kNN, SVM, Decision Trees), it's pretty fast and reasonably competitive in the quality of its results. A paper by Fabrizio Sebastiani provides a really good introduction to text categorization: http://faure.iei.pi.cnr.it/~fabrizio/Publications/ACMCS02.pdf

This module provides a convenient way to perform cleanup or other forms of resource management at the end of a scope. It is particularly useful when dealing with exceptions: the Scope::Guard constructor takes a reference to a subroutine that is guaranteed to be called even if the thread of execution is aborted prematurely. This effectively allows lexically-scoped "promises" to be made that are automatically honoured by perl's garbage collector. For more info, see: http://www.drdobbs.com/cpp/184403758

This module replaces the standard localtime and gmtime functions with implementations that return objects. It does so in a backwards compatible manner, so that using localtime/gmtime in the way documented in perlfunc will still return what you expect. The module actually implements most of an interface described by Larry Wall on the perl5-porters mailing list here: http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2000-01/msg00241.html

Test::Spec is a declarative specification-style testing system for behavior-driven development (BDD) in Perl. The tests (a.k.a. examples) are named with strings instead of subroutine names, so your fingers will suffer less fatigue from underscore-itis, with the side benefit that the test reports are more legible. This module is inspired by and borrows heavily from RSpec (http://rspec.info/documentation/), a BDD tool for the Ruby programming language.

The Xoltar Toolkit contains utility modules for Python, including functional programming support, lazy expressions and data structures, and thread pools. It includes support for closures, curried functions, lazy expressions, lazy tuples (functional programming languages call these lazy lists, but since lists are mutable in Python, tuples are closer in meaning), and lazy equivalents for map, filter, reduce, and zip. It also includes some higher-order functions for composing functions. See also: http://www-106.ibm.com/developerworks/library/l-prog.html
