Study anticapitalism and go on from there. I`d recommend anarchism and World History.
Ps.: In tech & programming specifically, I think Free Software is a beautiful idea.
Ps.: I`ll add, why I think this is(my original point), is that I think it's very nice to understand(or try to understand) what is the `structure/mechaniscs of the world`, I mean, to me it would be the same to study capitalism as it is to study anticapitalism(that is, the more you see how it works, the more you`ll see stuff that is flawed), some would disagree with this, of course. Contrary to what many think, ideology to me means NOT seeing reality as it is(so I'm not talking about intantile, superficial, ideas/agenda here), so I think it's absolutely fair the everybody should take some understanding of it based on people who wanted to figure out found out, even if not 100%. Since the more correct is your model of things, the better you can act on them(you can't engineer a car with wrong math, for example). To me, personally, getting my mind out of the techie neophile mindset and knowing broader and deeper stuff gives me plenty of ideas on things to do. Even more so, that since I'm using this 'footing', I can then try to see if it matches reality and goes on to have real-world effects! ;P But anyway, what I`m saying is sort of a longer road, to try to get interested and understand other topics and then look to your habilities and see what you can do with them about the other thing. That's where the project I'm trying to work on came from and it's really meant to be a drop in the ocean and a simple program etc, but it's something I really care about since it's tied to deep layers of my person and perspective on `world`, `society`, `individuals`, `species`, etc.
