UAC Whitelist Hole In Windows 7
Microsoft went an interesting way with UAC and security in Vista. If you are running as a normal user, then if you attempt to do an operation that requires elevated priviliges, then you get prompted for an admin user id and password. Which is what you want.
Where it goes weird is if you are running as administrator then it prompts you with the allow or deny box. This is silly for power users, but for people who only used the older versions of windows and don't know much about the other user rights model in other OSes, then at least it does provide some information that some software is trying to do something significant.
I always thought the point of UAC was to push people to run as a normal user for their day to day operations. However, I don't believe Microsoft attempted to do even a little bit of education and the UAC prompt itself is not very informative.
However, I don't think Microsoft should be blasted for UAC: They tried something new and interesting to attempt to make their OS more secure.
As for the story, as long as the behavior when running as a normal user is not affected, then I don't really think it matters.
Diamond Age Approaching?
Fine. We have universal constructors, but we still need to know how to program those machines to do what we want.
Will we really know in 10 years how to properly pin point a race / group and be able to execute the biggest genocide ever?
Will we know how to use it to make a mighty nuke?
It is obviously important to think about those things but knowing how to use a hammer and a saw does not make you a home builder.
