Seriously, what's the point? I'm not saying it's pointless, but if the goal is to learn more about technology, why programming? Unless you're actually going to use it somehow, it's going to be a tremendous pain in the butt to learn and retain all these new ideas. Even if you do learn a bit about programming, there are always going to be professionals out there that can do it faster, more efficiently, and more securely than you can -- and if it's something for a business, you should probably be going with them.
If all you want to do is learn more about technology, subscribing to Popular Mechanics and reading it every month would be a good place to start. Or even just reading Slashdot every day.
If the goal is to learn more about computers, then it would probably be a lot more practical to learn about hardware than programming. Learn what the different basic parts of a computer are, what they look like, what types there are, how to replace them... that kind of stuff.
For a car analogy, instead of learning about the software that makes your car work, you should be learning about how to change the fluids and diagnose simple problems, check the tire tread... that kind of stuff.
