In order to keep my life in order I have for many years used a task management system based on Getting Things Done (GTD) by David Allen. Initially I used a system called Life Balance on PC and Palm then moved to My Life Organised on PC and Windows Mobile.
I like the way that both of these systems work but as a software guy I have always thought “I can do that!”. So now I am putting my money where my mouth is and have started my own open source GTD project. Initially I am implementing a library to handle the GTD data items (Tasks, Contexts, etc.), this will be followed by desktop, mobile and, maybe, web applications that all use the library.
The library is called BjbGtdLib, is written in Java using NetBeans and is hosted on Kenai.
Go take a look!
