Provides a framework to perform Non-negative Matrix Factorization (NMF). The package implements a set of already published algorithms and seeding methods, and provides a framework to test, develop and plug new/custom algorithms. Most of the built-in algorithms have been optimized in C++, and the main interface function provides an easy way of performing parallel computations on multicore machines.

libranlip is a C++ library created by G. Beliakov, which generates random variates with arbitrary Lipschitz-continuous densities via the acceptance / rejection method. The density should have a dimension of no more than about five. The user needs to supply the density function using a simple syntax, and then call the methods of construction and generation provided in libranlip.

nordlicht is a tool that converts video files into colorful barcodes. nordlicht is free software, supports a large number of styles, and is optimized for speed. It comes with a software library written in C that allows for easy integration into other programs.

This is a singleton class for parsing XML into a tree structure. How does this differ from other XML tree generators? By using XML::Parser::Lite, which is a pure perl XML parser. Using this module you can tree-ify simple XML without having to compile any C.

The pod2mdoc utility is a converter from POD into mdoc. It's meant to operate like pod2man; however, it doesn't require a Perl installation: pod2mdoc is a standalone ISC-licensed ISO C utility and should compile on any modern UNIX system.

PyEnchant is a set of language bindings and some wrapper classes to make the excellent Enchant spellchecker available as a Python module. The bindings are generated using SWIG. It includes all the functionality of Enchant with the flexibility of Python and a nice 'Pythonic' object-oriented interface. It also aims to provide some higher-level functionality than is available in the C API.

Catalyst::Helper::Controller::Scaffold is a helper for scaffolding for Catalyst, which adds easy scaffolding: # Imagine you want to generate a scaffolding controller MyApp::C::SomeTable # for a CDBI table class MyApp::M::CDBI::SomeTable script/myapp_create.pl controller SomeTable Scaffold CDBI::SomeTable

wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a Python extension module (native code) that wraps the popular wxWidgets cross platform GUI library, which is written in C++.

Net::DNS::Resolver::Programmable is a Net::DNS::Resolver descendant class that allows a virtual DNS to be emulated instead of querying the real DNS. A set of static DNS records may be supplied, or arbitrary code may be specified as a means for retrieving DNS records, or even generating them on the fly.

Honeyd is a small daemon that creates virtual hosts on a network. The hosts can be configured to run arbitrary services, and their TCP personality can be adapted so that they appear to be running certain versions of operating systems. Honeyd enables a single host to claim multiple addresses - I have tested up to 65536 - on a LAN for network simulation.
