nl is a python library, that exposes a declarative API that allows us to build sentences and rules. These are used as input for a knowledge base built on the CLIPS production system. CLIPS builds a Rete network with the rules and sentences, which can then be queried for the consecuences of those in a most efficient way.

The main claim of nl is to offer a syntax that can accommodate any coherent theory that we may build with the natural language (in the same sense as something like the semantic web's OWL-Full would), while at the same time being based on a simple finite domain first order theory. This theory is NL, a discussion of which can be found here. This discussion is probably required reading to understand the breadth and the limits of nl, but not to start using it.

Cherry Blossom is a blogging system written in Python. It was written specifically because I had a lot of pyblosxom blog entries on my previous blog, but I wanted to use cherrypy instead of plain-ol cgi. It adds features like object publishing, session support, access to lots of cherrypy plugins, access to GET and POST vars as method parameters, and others. This software's been running my blog (http://billmill.org) for over two years now, and has survived a couple redditings and a flood from stumbleupon, all without a hiccup.

— a development environment for making digital art

Field is an open-source software project initiated by OpenEnded Group, for the creation of their digital artworks. It is an environment for writing code to rapidly and experimentally assemble and explore algorithmic systems. It is visual, it is hybrid, it is code-based. We think that it has something to offer a diverse range of programmers and artists.

Based on ideas started at the MIT Media Lab, Field was in development in-house for around 6 years. But for the last 16 months it has been quietly available online as an open source project. We are pleased to announce the initial "beta" binary open-source releases for Intel-based Macs OS X 10.5 or 10.6.

This library provides a Python Language API for visualization of air traffic situation.

Generally “fail fast” is a good engineering principle, because it’s helps you find problems sooner, and makes debugging much easier.

solrpy is a python client for solr, an enterprise search server built on top of lucene. solrpy allows you to add documents to a solr instance, and then to perform queries and gather search results from solr using your favorite programming language--python.

PyLucene is a Python extension for accessing Java Lucene. Its goal is to allow you to use Lucene's text indexing and searching capabilities from Python. It is API compatible with the latest version of Java Lucene, version 2.9.0 as of October 13th, 2009.

PyLucene is not a Lucene port but a Python wrapper around Java Lucene. PyLucene embeds a Java VM with Lucene into a Python process. The PyLucene Python extension, a Python module called lucene, is machine-generated by JCC.
