Largest Prime Number Ever Found
http:// www.newscientist.com/news/news.jsp?id=ns99994438

A 26-year-old graduate student in the US has made mathematical history by discovering the largest known prime number. The new number is 6,320,430 digits long. It took just over two years to find using a distributed network of more than 200,000 computers. Michael Shafer a chemical engineering student at Michigan State University used his office computer to contribute spare processing power to the Great Internet Mersenne Prime Search (GIMPS). The project has more than 60,000 volunteers from all over the world taking part.

"I had just finished a meeting with my advisor when I saw the computer had found the new prime," Shafer says. "After a short victory dance, I called up my wife and friends involved with GIMPS to share the great news."

Prime numbers are positive integers that can only be divided by themselves and one. Mersenne primes are an especially rare type of prime that take the form 2 p-1, where p is also a prime number. The new number can be represented as 220,996,011-1. It is only the 40th Mersenne prime to have ever been found.

New Largest Known Prime Number
http://www.mersenne.org/24 036583.htm

Josh Findley, a volunteer in the Mersenne.org research project called the Great Internet Mersenne Prime Search (GIMPS), has discovered the largest known prime number. Findley used his home PC and free software by George Woltman and Scott Kurowski as part of an international grid of 240,000 networked computers in virtually every time zone of the world. The new number, expressed as 2 to the 24,036,583th power minus 1, has 7,235,733 decimal digits and was discovered May 15th. It is nearly a million digits larger than the previous largest known prime number, and belongs to a special class of rare prime numbers called Mersenne primes . The discovery marks only the 41st known Mersenne prime, named after Marin Mersenne , a 17th century French monk who first studied the rare numbers 300 years ago. Mersenne primes are most relevant to number theory, but most participants join GIMPS simply for the fun of having a role in real research - and the chance of finding a new Mersenne prime.

Of all the personal computers to be unwrapped during the holiday season, more than 80 percent will be used to go online and search the Web's more than 92 million gigabytes of data (comparable to a 2 billion-volume encyclopedia). Getting online is the easy part, finding a useful Web page is a bit harder—keeping track of a useful Web page is another issue altogether.

People have devised many tricks—such as sending e-mails to themselves or jotting on sticky notes—for keeping track of Web pages, but William Jones and Harry Bruce at the University of Washington's Information School and Susan Dumais of Microsoft Research have found that often people don't use any of them when it comes time to revisit a Web page. Instead, they rely on their ability to find the Web page all over again.

Keeping Found Things Found on the Web


Keeping Found Things Found on the Web 01/28/2004 08:56 AM
Keeping Found Things Found on the Web - A Research Project of the Information School at the University of Washington
http://kftf.isc hool.washington.edu/projKFTF.asp
http://kftf .ischool.washington.edu/publications.asp

The goal of this study is to understand better the ways in which people manage information for subsequent re-access and re-use. The study focuses on the management of information found on the Word Wide Web. Follow-on studies will look at similar problems and practices of personal information management for other information types including email and personal files (electronic and paper-based). The classic problem of information retrieval, simply put, is to help people find the relatively small number of things they are looking for (books, articles, web pages, CDs, etc.) from a very large set of possibilities. This classic problem has been studied in many variations and has been addressed through a rich diversity of information retrieval tools and techniques.

A follow-on problem also exists which has received relatively less study: Once found, how are things organized for re-access and re-use later on? What can be done to avoid the need to repeat the entire search process? We refer to this as the problem of Keeping Found Things Found. The current study addresses this problem in the context of World Wide Web use. The study focuses on use of the Web by managers, researchers, librarians and other information specialists. But it is expected that the results of the study will be relevant to most users of the Web.

What's Prime Time? 12/11/2003 05:06 AM
Prime time TV may quickly be a thing of the past. While the rise of personal video recorders like TiVo mean time shifting shows out of prime time (or, into prime time) is playing a role, new studies are suggesting that many people are simply giving up television programming for alternatives like the internet, DVDs and video games. Broadcasters were so surprised by the severity of the numbers in one recent ratings report that they originally claimed that the data must be bad. However, there's plenty of evidence to suggest that there's quite a large movement away from broadcast television. What the broadcasters still don't realize is that people are beginning to realize that they want more control over their entertainment time. They don't want to be force-fed what a producer picks. They wanter interactivity or they want choice - which goes against the entire broadcast mentality. In the meantime, the advertisers are realizing that this shift is happening, and thus are moving their advertising dollars to other venues such as the internet and video games.

Most of the time I'm happy to get things with free shipping a week later, but if it averages out to just a couple of dollars per order (and ~$0.75 per item)? Hmn. They should do something to get the marketplace vendors to use the program too......

Monarch sacks PM by text message: Even the mighty fall, this time by pager message.

The practice of breaking bad news by text message is a growing trend as people increasingly shun face-to-face confrontation. In the most unusual instance of such an act to date, the King of Swaziland has sacked his Prime Minister in 160 characters or less.

King Mswati of Swaziland has enraged local lawmakers after it emerged he instructed his attorney general to fire Prime Minister Sibusiso Dlamini by SMS text message.
