In January 1961, on a snowy and unusually cold day in New York City, J. Murray Mitchell, Jr. of the U.S. Weather Bureau's Office of Climatology told a meeting of meteorologists that the world's temperature was falling.
[...]Around 1980 two groups undertook to work through the numbers in all their grubby details, rejecting sets of uncertain data and tidying up the rest.
One group was in New York, funded by NASA and led by James Hansen. They understood that the work by Mitchell and others mainly described the Northern Hemisphere, since that was where the great majority of reliable observations lay. Sorting through the more limited temperature observations from the other half of the world, they got reasonable averages by applying the same mathematical methods that they had used to get average numbers in their computer models of climate. (After all, Hansen remarked, when he studied other planets he might judge the entire planet by the single station where a probe had landed.) In 1981, the group reported that "the common misconception that the world is cooling is based on Northern Hemisphere experience to 1970." Just around the time that meteorologists had noticed the cooling trend, such as it was, it had apparently reversed. From a low point in the mid 1960s, by 1980 the world had warmed some 0.2C.
Hansen's group looked into the causes of the fluctuations, and they got a rather good match for the temperature record using volcanic eruptions plus solar variations. Greenhouse warming by CO2 had not been a major factor (at least, not yet). More sophisticated analyses in the 1990s would eventually confirm these findings. From the 1940s to the early 1960s, the Northern Hemisphere had indeed cooled while temperatures had held roughly steady in the south. This was largely because of normal variations in natural forces, although industrial aerosol pollution had helped. Then the warming had resumed in both hemispheres.
The temporary northern cooling had been bad luck for climate science. By feeding skepticism about the greenhouse effect, while provoking some scientists and many journalists to speculate publicly about the coming of a new ice age, the cool spell gave the field a reputation for fecklessness that it would not soon live down.
Any greenhouse warming had been masked by chance fluctuations in solar activity, by pulses of volcanic aerosols, and by increased haze from pollution. Furthermore, as a few scientists pointed out, the upper layer of the oceans must have been absorbing heat. These effects could only delay atmospheric warming by a few decades. Hansen's group boldly predicted that considering how fast CO2 was accumulating, by the end of the 20th century "carbon dioxide warming should emerge from the noise level of natural climatic variability." Around the same time, a few other scientists using different calculations came to the same conclusion -- the warming would show itself clearly sometime around 2000.

And others like to spend their spare time doing something with their computer (and be it just something aiding their actual hobby), not banging together the innards. To them this would not only not save them money, it would be a complete waste of time.
Proposing they should build their own PCs in endless posts is time you wasted not building your own PC. Get to it already, and leave the others alone with your (to them) totaly worthless opinion.
Just to put that into perspective: There was about 23 kg of Pu-238 aboard the Cassini probe. The same amount of caffeine would be in 230,000 12 oz cans of Jolt Cola (or espressos, if you prefer).
But the Smart Folders idea goes back much deeper in Apple history -- in fact, it pre-dates Jobs' Second Coming. Smart Folders used to be called "Views" and they were a pre-announced feature of Copland, the ill-fated OS that was eventually replaced by the NeXT OS. (It drew on the V-Twin text indexing that did make it into OS 9, I believe, and may well still be a part of OS X.) I saw a demo of Views when I visited Apple in 1996, and it made such a strong impression that I wrote about it in my first book, Interface Culture:
Apple's V-Twin implementation lets you define the results of a search as a permanent element of the Mac desktop -- as durable and accessible as your disk icons and the sub-folders stacked beneath them. In Apple's language, these new items are called "Views," for reasons we will come to understand. At first glance, a View looks and behaves like your average folder or sub-directory: it is represented by an icon; clicking on that icon opens a window that contains other icons, representing assorted files; clicking on one of those icons opens the appropriate document. So far so good. Things get tricky, however, when we try to add a file to a View manually, by dragging an icon over the View's window... The user has only indirect control over the contents of a View. He or she specifies its general attributes, using the language of the V-Twin search engine: "find all documents on my hard drive that are likethis other document." The computer then decides which documents fulfill that request, and places them in the View window. (Technically speaking, it places copies -- or "aliases" -- of each document in the View; the originals remain in their previous locations.) Unlike the temporary results of a "find file" request, the View window has what programmers call "persistence."Like an ordinary folder, the View remains on your desktop until you throw it away. During that lifespan, the V-Twin software regularly updates the View's contents whenever new files arrive that match the original search request.
I think it's pretty ironic that the most highly-touted feature in Tiger is one they've been trying to get into a shipping OS for almost ten years. Sometimes information society isn't quite as fast as it's rumored to be.
Err, nope. What was described as "piles" in one rumor was actually Exposé. The Apple developed interface concept called "Piles" is actually something different. And the "rumors about a mouse with a wheel on it" are based on an Apple patent named "Mouse having a rotary dial" that describes a "user operated input device includes a housing and a rotary dial positioned relative to an external surface of the housing. The rotary dial provides a control function."

What overhead? A few percent when you actually use the GUI.
See, and there is the solution: President Jeb Bush will just cool the world with a nucular winter.
Actually, most genies do exactly what they are told, not a thing more.
Nitpick: In Germany we don't have "copyright", but "Urheberrecht" - "originator/author right" which usually lies with the author.
But you didn't say "... before the deadline."
Because the porn industry didn't ask Apple to do one with them?

Could your words be interpreted as "Everybody claiming that Apple won't fix your Mac on warranty after you opened it is a stinking liar"?
Any USB Audio (in) device should work.
Yeah, those will buy bigger devices, with less memory, for more money.
The sentence from the Times Dispatch is refering to the Al13 cluster, the Scientist talks about the Al14 cluster.
the lobster said his name was Lokai, and his race os blue-and-brown lobsters were at war with this race of brown-and-blue lobsters...
And in other countries it is legal to buy dope and marry a 14 year old. Now try to go back to America with your drugs and new sex partner.
Did you even bother to look at the purty pigshures?

The StarWars action figures are actually larger than life sized.
So where are the craters here? All those meteorites lying around in the desert without a visible crater.
After this and this.
Well, I thought the Slashdot crowd wasn't of the "No user serviceable parts inside? Mommy, this thing scares me!" type.
No, Microsoft fires guy for posting pictures of boxes of Apple G5s on the MS campus.
