A zero-day exploit is a method of hacking a system. It's sort of a vulnerability that has an exploit written for it, sort of a key and a lock that go together to a given software package. It could be an internet web server. It could be Microsoft Office. It could be Adobe Reader or it could be Facebook.

The greatest fear that I have regarding the outcome for America of these disclosures is that nothing will change.

The big tech companies understood that the government had not only damaged American principles, it had hurt their businesses.

Someone recently talked about mass surveillance and the NSA revelations as being the atomic moment for computer scientists. The atomic bomb was the moral moment for physicists. Mass surveillance is the same moment for computer scientists, when they realize that the things they produce can be used to harm a tremendous number of people.

I believe that at this point in history, the greatest danger to our freedom and way of life comes from the reasonable fear of omniscient State powers kept in check by nothing more than policy documents.

So when they say I'm a low-level systems administrator, that I don't know what I'm talking about, I'd say it's somewhat misleading.

I don't want to live in a world where there's no privacy, and therefore no room for intellectual exploration and creativity.
