"I don't think the U.S. government even realized how far it had spread,"
who's the numbnuts who thought it would be a great idea to make this information available to anyone who asks for it?
Changing the color of a link you've visited has been around forever. Changing the style of a link you've visited to one that can send information back to the server eg "background-image:url(/visited.pl?site=slashdot)", that's newer.
Sorry but I don't think I fully understand how that relates to this story. Would you elaborate please? What you describe there sounds like a re-implementation of so-called "http ping."
By putting this CSS under an a:visited selector, they only get the ping if the link points to a URL you have visited. Though they can't get your entire history list, they can query whether (your browser thinks) you've been to a specific page.
You're right. According to that document (p. 4, about halfway down), the machine draws 1.6 to 2.7 W (depending on model) in standby; 1.5 to 2.1 W in soft-off with wake-on-LAN enabled; and no power in soft-off with wake-on-LAN disabled ("wake up power button only"). So the article is simply wrong when it says the computer is "able to use no power while in standby mode", unless they're redefining "standby" to mean S5 rather than S3.
It may simply be that, when WOL is disabled, shutting down the machine puts it into "mechanical off" rather than "soft off"—just like in pre-ATX PCs.
Never ask two questions in a business letter. The reply will discuss the one you are least interested, and say nothing about the other.
