Internet Resources for Understanding This Brave New Digital World
This page has a collection of things about the ideas of Free and/or Open Source software, hardware, and computer-related culture. (FOSS: "Free / Open Source Software")
There is an ongoing set of controversies (in philosophy, priorities, and practice) among the Free and/or Open Source community. You can't learn to understand the digital world without understanding FOSS, but understanding FOSS requires understanding the controviersies. Sorry.
