Karma is a Web service provider for tracking "karma" points of users who are distributed across several separate Web applications. It is useful for when sites want to allow community contributions to content, but certain higher types of content should only be able to be submitted by people who have demonstrated the ability to contribute value at lower levels. The vision is to create a generic karma service where a central server instance provides its services to several related Web applications. Those applications are the clients of the karma server instance. They can quickly and securely submit and retrieve karma for their users.
XapianFu is a Ruby library for working with Xapian databases. It builds on the GPL licensed Xapian Ruby bindings, but provides an interface more in-line with "The Ruby Way"(tm) and is considerably easier to use. For example, you can work almost entirely with Hash objects, and XapianFu will handle converting the Hash keys into Xapian term prefixes when indexing and when parsing queries. It also handles storing and retrieving hash entries as Xapian::Document values. XapianFu basically gives you a persistent Hash with full text indexing (and ACID transactions).
GPS Tool is a flexible tool for downloading and processing GPS data on Mac OS X. The tool itself is a front-end for various cross-platform tools, namely GPS Babel and scripts which are used to download GPS data. The tool is very easy to use and allows you to define preset processing scripts for batch processing large amounts of GPS data. The plugin system allows you to integrate device discovery and GPS data download into an easy-to-use GUI.
Winnow efficiently trains and operates any number of unique Bayesian (Naive Bayes) classifiers on large sets of content. It has very high performance and works with very small training and unbalanced training sets. It has been used to power an innovative Web feed reader that uses smart tags, which learn and find the content you want to see, from more sources than you can follow with traditional feed readers. It works particularly well with Ruby and Ruby on Rails.
