I've honestly thought of hacker spirit as embodying a kind of homesteader ethos in a way. There's this homesteading book I bought a long time ago when I was in college, rich with illustrations on how to do everything from raise animals and grow food to building a house, processing lumber, drilling a well, everything. The same fascination I have with homesteading and DIY culture extends into my interest in technology, and I suspect this is the same with a lot of developers as well.
