There is a lot of information in:

and in its sequel: Dark Sun.
These are historical works, but they contain all the necessary *scientific and technological principles* to build a nuclear weapon, if you complete that with normal engineering competence. That doesn't mean that you have a *manual* to give to a technician to build a bomb, but all the scientific principles are there.
All the physical data you need can be found on: http://www.nndc.bnl.gov/
This is all the science you need to go of. The difficulty in making a nuclear weapon doesn't reside in knowing or not knowing the science and technology. It resides in the capital investment needed, and the visibility of your endeavour. And you will still need to "tune" practical stuff. For beginners, I would suggest a U-235 bomb. That's what the US started with on Hiroshima too. The plutonium bombs are harder to trigger (all the science is there, but to get the trigger right is tricky, and a matter of classical fireworks).
The reason why people don't make nuclear bombs in their basement is simply that it takes a huge capital investment, and that it will be noticed and that you will get a few classical bombs on your practice area before you really get off. Not that its science would be hidden.
Economically, that only makes sense if one can use state privileges. If you cannot use state privileges, the most efficient technology will also be the most profitable.
However, the point is that many embryonic technologies LOOK simple and efficient at naive first sight. The fact that it isn't done in reality then gives rise to conspiracy theories. But the real truth is that the technology is MUCH HARDER to put in practice than at first sight.
Do you mean "controlling you" or do you mean "spying on you" ? Controlling can be fought by learning, informing, and practising logic and science to a limited extend. The spying can be rendered difficult or useless. I run things like trackmenot, that do hundreds of random and bogus internet searches. I'm working on a project to send noise over the internet. You remember the Danish reaction to the Nazi chasing the Jews there ? Everybody put up a yellow David star.
This is nothing but the quirks of the fiat system. It is a fascinating engine. Luxembourg is one of the richest countries in the world, btw. These "debts" don't mean anything. If anything, a national debt only means how much money the country as put in circulation. That is the initial meaning of state debt. It has not the meaning of an actual debt. This is a very, very deep misunderstanding, because of the very strange nature of the fiat system. A very high debt only indicates that your country has managed to rip off the rest of the world a lot. Something to be proud of
