Apple is marketing the iPad as a computer, when really it's nothing more than a media-consumption device - a convergence television, if you will. Think of it this way: One of the fundamental attributes of computers is that they are interactive and reconfigurable. You can change the way a computer behaves at a very deep level. Interactivity on the iPad consists of touching icons on the screen to change which application you're using. Hardly more interactive than changing channels on a TV.

Let's bring back barratry, maintenance, and champerty for patent lawsuits.

Combine that with a limitation on the assignment of patents and a lot of patent trolls would be out of business.

JUST suppose that Darwin's ideas were only a part of the story of evolution. Suppose that a process he never wrote about, and never even imagined, has been controlling the evolution of life throughout most of the Earth's history. It may sound preposterous, but this is exactly what microbiologist Carl Woese and physicist Nigel Goldenfeld, both at the University of Illinois at Urbana-Champaign, believe. Darwin's explanation of evolution, they argue, even in its sophisticated modern form, applies only to a recent phase of life on Earth.

At the root of this idea is overwhelming recent evidence for horizontal gene transfer - in which organisms acquire genetic material "horizontally" from other organisms around them, rather than vertically from their parents or ancestors. The donor organisms may not even be the same species.

Andrew Carlson along with Prof. Tom Mitchell and other researchers at Carnegie Mellon University have developed an artificial intelligence language-learning program that never ends.

It simply continues to run and learn more of the English language every day.

The idea is that the Web contains so much information to be extracted, and has so much new information added each day, that an AI program can continuously mine it without its knowledge ever reaching a plateau.

But this was not just a rhetorical or a fictional conceit. A turn-of-the-century confidence man named George C. Parker actually sold the Brooklyn Bridge more than once. According to Carl Sifakis, who tells his story in "Hoaxes and Scams: A Compendium of Deceptions, Ruses and Swindles," Parker - who was also adept at selling the Metropolitan Museum of Art, the Statue of Liberty and Grant's Tomb - produced impressive forged documents to prove that he was the bridge's owner, then convinced his buyers that they could make a fortune by controlling access to the roadway. "Several times," Mr. Sifakis wrote, "Parker's victims had to be rousted from the bridge by police when they tried to erect toll barriers."

After long-term exposure to electromagnetic waves such as those used in cell phones, mice genetically altered to develop Alzheimer's performed as well on memory and thinking skill tests as healthy mice, the researchers wrote in the Journal of Alzheimer's Disease.

Proposals to suspend the internet connections of those who repeatedly share music and films online will leave consumers with a bill for £500 million, ministers have admitted.

...

Ministers have not estimated the cost of the measures but say that the cost of the initial letter-writing campaign, estimated at an extra £1.40 per subscription, will lead to 40,000 households giving up their internet connections. Impact assessments published alongside the Bill predict that the measures will generate £1.7 billion in extra sales for the film and music industries over the next ten years, as well as £350 million for the Government in extra VAT.

Did our Neolithic ancestors turn to agriculture so that they could be sure of a tipple? US Archaeologist Patrick McGovern thinks so. The expert on identifying traces of alcohol in prehistoric sites reckons the thirst for a brew was enough of an incentive to start growing crops.

Anyone operating a server on any scale should want a digital certificate to encrypt data between clients and services, whether for personal, office, or public use. Ars tells you how to obtain and install one, for free.

I had a discussion recently with friends about the various depictions of space combat in science fiction movies, TV shows, and books. We have the fighter-plane engagements of Star Wars, the subdued, two-dimensional naval combat in Star Trek, the Newtonian planes of Battlestar Galactica, the staggeringly furious energy exchanges of the combat wasps in Peter Hamilton's books, and the use of antimatter rocket engines themselves as weapons in other sci-fi. But suppose we get out there, go terraform Mars, and the Martian colonists actually revolt. Or suppose we encounter hostile aliens. How would space combat actually go?
