There are many projects I have worked on over the years. These, however, are the ones I'm still active enough in to care about sharing.
Godm
is a DataMapper for GObject. Its very simple in its current phase, but I'm using this in my own applications and that should help push it forward.
Catalina
is an object oriented database (OODB) library for GObject. It supports transactions, custom serialization, and indexes while providing a simple and fast API. This is still in early development but is rapidly solidifying.
MonoDevelop
is an integrated development environment for .NET related languages. It has the support for other languages, they just have not been implemented. The target audience is Linux users on the GNOME desktop, but many others take advantage of this great development platform. My contributions include the initial database framework, logging framework, splash screen work, and small patches to fix specific bugs.
Mono
is a cross-platform implementation of the .NET framework. It is completely white-room reverse engineered and supports a very broad range of tools and applications for the .NET framework. My contributions included documentation, bug fixes, and some database functionality.
Marina
is a RSS and Syndication reader for use within the GNOME desktop environment. It plays nicely with the emerging technologies around the desktop such as libnotify, dbus, gnome-vfs and gconf among others. Marina has lots of custom widget goodness!
Moneyclip
is a personal finance application for the GNOME desktop environment. It aims to be simple to use for personal and small-family use. While not ready for prime-time, much of the framework to get there is already in place.
Thanks for your time, and please consider contributing to any of these projects if your talents fit! And everyone can do documentation.
