Submission + - Watson solved the easy problem (i-programmer.info)

mikejuk writes: Within all of the fuss and talk of the "day of the machine" Watson, IBM's question answering machine isn't all its cracked up to be — it isn't a question answering machine but an answer questioning machine and this could just be a whole lot easier.
The Jeopardy! task is actually to find a entity that is defined by the clues provided. Once Watson has the defined entity it just converts it into a question. This way round makes it much easier for the statistical language processing and AI methods that Watson uses.
It is a neat trick to pull off but it probably doesn't lead to general purpose question answering devices.

Submission + - IBM's Watson May Be More Human Than We Think (computerworld.com)

Lucas123 writes: IBM's Watson computer that handily beat Jeopardy's past champions this week may have a lot of hardware behind it — including 90 servers and 21.6TB of hard drive capacity — but in the end it's very similar in computational capability to that of a human brain. If Ray Kurzweil is correct, and the average human brain holds 1.25TB of data and has 100 teraflops of compute capacity, then Watson which is an 80-teraflop system with 1TB of memory in use, is actually an underachiever. 'Yes, we could have handled a lot more information. We could have put more memory in each server, but once we got the answers to three seconds, we didn't need to go further,' said Tony Pearson, master inventor and senior consultant at IBM.

Apple Releases IOS 4.3 Beta To Developers 101

m2pc writes "Apple has just released iOS 4.3 beta to developers. New features include: Developer access to AirPlay API, Four and Five-finger gestures, and the return of the hardware orientation lock for iPad, a feature that upset many when Apple suddenly removed this feature with no software option to re-enable it. Also interesting to note is the lack of mention of the Mobile Hotspot feature rumored to be included in 4.3 for all iOS devices by the Verizon announcement yesterday."

EVE Online Battle Breaks Records (And Servers) 308

captainktainer writes "In one of the largest tests of EVE Online's new player sovereignty system in the Dominion expansion pack, a fleet of ships attempting to retake a lost star system was effectively annihilated amidst controversy. Defenders IT Alliance, a coalition succeeding the infamous Band of Brothers alliance (whose disbanding was covered in a previous story), effectively annihilated the enemy fleet, destroying thousands of dollars' worth of in-game assets. A representative of the alliance claimed to have destroyed a minimum of four, possibly five or more of the game's most expensive and powerful ship class, known as Titans. Both official and unofficial forums are filled with debate about whether the one-sided battle was due to difference in player skill or the well-known network failures after the release of the expansion. One of the attackers, a member of the GoonSwarm alliance, claims that because of bad coding, 'Only 5% of [the attackers] loaded,' meaning that lag prevented the attackers from using their ships, even as the defenders were able to destroy those ships unopposed. Even members of the victorious IT Alliance expressed disappointment at the outcome of the battle. CCP, EVE Online's publisher, has recently acknowledged poor network performance, especially in the advertised 'large fleet battles' that Dominion was supposed to encourage, and has asked players to help them stress test their code on Tuesday. Despite the admitted network failure, leaders of the attacking force do not expect CCP to replace lost ships, claiming that it was their own fault for not accounting for server failures. The incident raises questions about CCP's ability to cope with the increased network use associated with their rapid growth in subscriptions."

The Perfect Way To Slice a Pizza 282

iamapizza writes "New Scientist reports on the quest of two math boffins for the perfect way to slice a pizza. It's an interesting and in-depth article; 'The problem that bothered them was this. Suppose the harried waiter cuts the pizza off-center, but with all the edge-to-edge cuts crossing at a single point, and with the same angle between adjacent cuts. The off-center cuts mean the slices will not all be the same size, so if two people take turns to take neighboring slices, will they get equal shares by the time they have gone right round the pizza — and if not, who will get more?' This is useful, of course, if you're familiar with the concept of 'sharing' a pizza."

Battlestar Galactica Comes To an End 852

On Friday evening, Battlestar Galactica ended its four-season run as one of the most popular science fiction shows in recent history. 2.4 million people tuned in for the finale, and reactions to the ending — positive, negative, and often a mix of both — are springing up all over the internet, as are tributes and retrospectives. Producers Ron Moore and David Eick held a Q&A session after the finale to discuss certain aspects of the story and spell out the final status of several plot lines. Fans of the show will have a chance to see the Cylon side of the story this fall in a two-hour TV movie titled "The Plan," and we've previously discussed the spin-off prequel series, Caprica, the pilot for which will come out on April 21st. Be warned: these links and the following discussion will contain spoilers.
