A History of Software in 64 Programs

Monday, November 14th, 2011

This is a new exiting book project I’m working on now scheduled for release in 2012 with ISBN 978-1908043337. If your company would like to have its programs considered for inclusion please let me know and send a copy just in case I would need to include screenshots. I’ll update about this project soon.
