Projects

Database Adapter

For my contract I created a database adapter that embeds Python in a C application. The adapter translates ISAM calls from legacy C code to a MySQL database, making it possible to manipulate the data with modern tools without having to re-write all the legacy code. Python allowed a very quick development cycle, essential for software that does not initially have a clear design.

I also wrote data conversion utilities to moveprintouts from the customer's old application to the SQL database and a reporting program to create a government-required XML report. To manage the project I installed the excellent web-based trac project management system, also written in Python, and migrated Enigmatix, Inc.'s CVS repository to Subversion.

Multimedia Bindings

Boost.python is useful for exposing libraries written in C or C++ to Python. I have released bindings for ogg, vorbis, theora, shout, and xmms to allow Python programs to manipulate multimedia for streaming, encoding and decoding, and playback.

Networking Kit

I implemented the OSC networking protocol in Python to complement a server written in C++. This open source project has been successful, allowing at least one artist to control real-time 3d animation in Blender.

MIDP Game

Ported a Java applet to MIDP for play on a mobile phone.
