GeoTypes is a Python library that implements both the OpenGIS/PostGIS and standard PostgreSQL geometry types. It integrates with the psycopg Python/PostgreSQL interface. It provides implementations of all of the OpenGIS/PostGIS classes, except (x,y,m) and (x,y,z,m). It currently supports the EWKB, HEXEWKB, WKB, and WKT formats.
MyPixmania is an application that eases the use of the MyPixmania.com Web site. This Web site allows users to store picture albums, and sells the ability to send printed versions of these pictures. This application is easier to use than the site's Web-based form, especially when uploading a large number of pictures.
Shipyard is a module to process data in a format inspired by email headers (RFC 2822). The goal of shipyard is to have a simple, human readable, and human writable replacement for CSV that works better for long data and many rows and doesn’t need difficult escaping rules for special characters.
Moonshiner is a graphical frontend for Ghostscript's PostScript-to-PDF converter. While Ghostscript (and its wrapper ps2pdf) is a very powerful instrument, it is quite challenging to use its parameters on the command line, especially if you often change the settings as to what kind of color conversion, image resampling, etc. you want Ghostscript to perform. While the author has never used Adobe's Distiller, and thus cannot really compare the two, Moonshiner (as the name suggests) is supposed to be a work-alike for the Linux world (at least GUI-wise, as the actual work is of course done by Ghostscript).
PyMultimethods is a library that enables users to create multimethods (a.k.a. generic functions) in Python. In other words, you can create multiple versions of the same function/method. The one that is invoked depends on the runtime parameters. This is similar to polymorphism in the sense that the object type determines which version of the function is invoked. Multimethods go beyond the polymorphism found in conventional object oriented languages, however, because all parameters are taken into account (as opposed to only the "implied this", as in C++ or Java). PyMultimethods can also be used to "overload" a function or method.
