Nintendo to launch camera, music-capable DS: report

TOKYO (Reuters) – Japanese video game maker Nintendo Co Ltd plans to launch a new model of its DS handheld machine that can take pictures and play music by the end of the year, the Nikkei business daily said on Sunday.

The move would pit the top-selling portable game gear with Apple Inc iPod and camera-embedded cellphones in general.

The price for the new machine, which will also be equipped with advanced wireless communications functions, is expected to be below 20,000 yen ($189) in Japan, compared with 16,800 yen for the current model, the Nikkei said.

The Wii game console and DS have been Nintendo’s twin growth engines, helping its share price to grow more than three-fold over the past three years.

The DS far outsells Sony Corp’s rival machine, PlayStation Portable (PSP), globally.

But in Japan, the PSP’s unit sales exceeded the DS’s in five consecutive months through July, according to game magazine publisher Enterbrain, in a potential sign of slowing momentum for the current DS model.

Nintendo officials were not immediately available for comment.

Huge new prime number discovered

Los Angeles, Sep 28 (BBC Online) – Mathematicians in California could be in line for a $100,000 prize (£54,000) for finding a new prime number which has 13 million digits.

Prime numbers can be divided only by themselves and one.

The prize was set up by the Electronic Frontier Foundation to promote co-operative computing on the Internet.

Edson Smith, a mathemagician at the University of California Los Angeles installed software on to the department’s computers from the Great Internet Mersenne Prime Search (Gimps) to search for the new prime. Gimps is an ad-hoc network, like that PS3 Folding@home thing. Around 100,000 PCs worked together to perform 29 trillion calculations and locate a prime number that’s 12,978,189 digits long. I’d post the number but it would take you weeks to read it.

The team from the University of California at Los Angeles (UCLA) found the new number by linking 75 computers and harnessing their unused power.

This enabled them to perform the enormous number of calculations needed to find and verify a new prime.

Thousands of people around the world linked the powers of their personal computers in the search for a higher “Mersenne” prime number – named after 17th-Century French mathematician Marin Mersenne.

Mersenne primes are expressed as two to the power of P, minus one – with P being itself a prime number.

Edson Smith, the leader of the winning UCLA team, told the Associated Press news agency: “We’re delighted. Now we’re looking for the next one, despite the odds.”
