The AP explanation is exactly right. The value of an object reference is the reference itself. i.e. when you evaluate the reference, it's a no-op; you just get the reference back.
The entire goal of elementary school science education should be to convince kids that science is fun and interesting. When I was in elementary school, the teachers managed to make even the most interesting topics boring by forcing us to write reports and logs of everything we did. For someone who hated writing, this was torture. I think I like science despite elementary school, not because of it.
The reason he has to boot it twice sometimes is that the PRAM battery is dead; he needs to get a new one. The fact that it sometimes works probably means that the battery's voltage is right around the cutoff for working; he should really replace it if he intends to use the computer. The hardware of the 6100 has a weird quirk that causes boot failures if the PRAM battery is dead.
There's something fishy here. Icons in the Dock always bounce to the same height; they don't bounce "higher and higher." Are the computers NetBooted off a server? If so, network congestion could be the problem. Kerberos also shouldn't take nearly that long; perhaps your Kerberos server is obscenely slow. I think you're referring to issues specific to your (poor) implementation, not Mac OS X itself.
I worked on the project; shadowduck has it exactly right. GRACE had a map only after the map was provided at the registration desk; all navigation before arrival at the desk was done with vision and human-robot interaction.
The United States is located on North America, just as Canada is. Of course it's continental. It's the AAAI, not the USAAI (United States Association for Artificial Intelligence, which, as far as I know, doesn't exist).
Grace is controlled by two computers mounted inside it, each of which runs Linux. Metrica's vision system also has a dedicated computer running Linux. Speech recognition is done by Viavoice, which (unfortunately) runs on a Windows laptop, also mounted on the robot.

Vikia, the face, is female, since its developers felt that females tend to interact better socially. Since Vikia is female, and it was chosen for the robot, Grace cannot very well be either male or genderless, can it?
There's a discrepency between the article's title and the article's content. Your analysis is with respect to the title: "Are Mac users smarter?" However, the article never discusses the issue of intelligence. Instead, it claims that Mac users tend to be more affluent and better educated. I think that the problem with the article is really the mismatch between title and content; the article never makes any claims about intelligence whatsoever. There is a clear distinction between intelligence and affluence/education that the article doesn't address.
Standard car batteries are lead acid, but the batteries in hybrid cars are typically (IIRC) NiMH, not lead acid.

The "Search Google for" button is quite useful; I use it all the time. It's faster to use that than to first go to Google's web site and enter the query there.
CMU's Human Computer Interaction Institute (a href="http://www.hcii.cmu.edu/">http://www.hcii . mu.edu/ is worth a look - B.S., M.S., and Ph.D. degrees are offered.
How is this evidence of a good hardware division? Of course they replaced the defective mouse - any manufacturer would do that, but a good manufacturer wouldn't have shipped the faulty mouse in the first place. And isn't it possible that your "superior" mouse is the cause of your RSI?
It seems to me that there's another side to this issue. Don't they have a valid reason to monitor traffic? I mean, suppose they cached frequently used information, like some proxy servers do. They would have to monitor the traffic, in some sense, anyway, to know what to cache, and where to cache it. Perhaps the users would be better off with a caching system: more speed for less money.

Actually, most of it is in C++. :-)
No, that's just the low level mobility stuff. The AI is all done by higher level code that makes calls to Mobility.

Wrong. They could be using a Mac. Remember, Macs had folders long before Windows 95 came out.
