To get back the username and the picture, reverse the above procedure.

For the New Start Menu, Windows XP looks for the <username>.bmp file in the folder

C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures

If the file is not found, it takes a picture from the "Default Pictures" sub-folder. By renaming the <username>.bmp and the "Default Pictures" folder, you're giving no chance for Windows to fetch an image for the Start Menu

~ Cheers ~.

A "secret" about Barcodes

Did you ever wondered what barcodes mean?
I 'll not say much.
The most common barcode systems are two. EAN and UPC.
EAN meaning European Article Numbering System and is used in most countries including all Europe countries and other.
UPC stands for Universal Product Code and is used in USA and Canada.


This is a EAN bar code which i don't know if it's in use or no but it's okay to tell what I want.
As you noticed it has black and white lines and also some numbers.
The lines are read by machines called Bar Code Readers. But numbers can be read by anyone.
What do these numbers mean?
The meaning is very simple.
#0 and #1 show the product origin and the number coding system of the barcode.
#2 - #6 are the Manufacturer code
#7 - #12 are the product code
#13 is the checksum. It is used to check if the other number were read right. How is it calculate?
To calculate it you simply calculate the sum of even placed numbers (let's say it A) and the odd placed numbers (let's say it B).
Then you find C = A + 3 * B.
The #13 number is the number which you add to C that (C+#13)/10 = 0.
Actually is C%10 (modulo).

Please post any comments.

Top Social Networking Sites in India

Which is the most popular social networking site in India? Its not Facebook, its Orkut. Comscore in its latest report tracked the top social networking sites in India, and found that global social networking brands like Orkut, Facebook, hi5, LinkedIn and MySpace continued to gain prominence in India during the year.
They elaborate that Orkut is the most visited social networking site in India this December 2008 with more than 12.8 million visitors, an increase of 81 percent from the previous year. In fact Orkut’s audience is three times its nearest competitor Facebook.
Facebook is second most popular Indian social networking site with 4 million visitors, up 150 percent versus year ago. The third most popular social networking site is … surprise … Bharatstudent, with 3.3 million visitors (up 88 percent) followed by hi5 with 2 million visitors (up 182 percent).
Other popular networking sites in India featured in the list in descending order are ibibo, Myspace, LinkedIn, PerfSpot, BigAdds and Fropper. Now you have more sites to check out and track your friends.
I remember an earlier article tracking the most popular social network around the world, which suggested that LinkedIn might be the most popular social network in India, but watchful QOT readers Quakebo and Rajesh had commented even then that Orkut was the most popular one!
