Claimed Proof That P != NP 457

Posted by kdawson from the sufficiently-complex dept.
morsch writes "Researcher Vinay Deolalikar from HP Labs claims proof that P != NP. The 100-page paper has apparently not been peer-reviewed yet, so feel free to dig in and find some flaws. However, the attempt seems to be quite genuine, and Deolalikar has published papers in the same field in the past. So this may be the real thing. Given that $1M from the Millennium Prize is involved, it will certainly get enough scrutiny. Greg Baker broke the story on his blog, including the email Deolalikar sent around."
It's funny. Laugh.

Man Spends 2,200 Hours Defeating Bejeweled 2 179

Posted by Soulskill from the wins-complimentary-straight-jacket dept.
An anonymous reader writes "A California steel contractor spent 2,200 total hours over the last three years racking up a high score in Bejeweled 2. He exceeded the 2^31-1 maximum score programmed for the score display, proving that there is, in fact, an end to the game. I suppose congratulations or condolences are in order."

Brain Training Games Don't Train Your Brain 151

Posted by timothy from the maybe-it-just-takes-more-than-6-weeks dept.
Stoobalou writes with this excerpt from Thinq.co.uk: "A new study has shown that brain training games do little to exercise the grey matter. Millions of people who have been prodding away at their Nintendo DS portable consoles, smug in the knowledge that they are giving their brains a proper work-out, might have to rethink how they are going to stop the contents of their skulls turning into mush."

Submission + - Smarter-than-Human Intelligence (singinst.org)

runamock writes: "Brilliant technologists like Ray Kurzweil and Rodney Brooks are gathering in San Francisco for The Singularity Summit. The Singularity refers to the creation of smarter-than-human intelligence beyond which the future becomes unpredictable. The concept of the Singularity sounds more daunting in the form described by statistician I.J Good in 1965: 'Let an ultraintelligent machine be defined as a machine that can far surpass all the intellectual activities of any man however clever. Since the design of machines is one of these intellectual activities, an ultraintelligent machine could design even better machines; there would then unquestionably be an 'intelligence explosion,' and the intelligence of man would be left far behind. Thus the first ultraintelligent machine is the last invention that man need ever make.' What do Slashdotters think about the hypothetical Singularity? Could it happen and what are the technologies that are likely to lead us to the Singularity?"
