Raymond Samuel Tomlinson (born 1941, Amsterdam, New York) is a programmer who implemented an email system in 1971 on the ARPANET. Email had been previously sent on other networks such as AUTODIN and PLATO. It was the first system able to send mail between users on different hosts connected to the ARPAnet. (Previously, mail could be sent only to others who used the same computer.) To achieve this, he used the @ sign to separate the user from their machine, which has been used in email addresses ever since.
The first email Tomlinson sent was a test e-mail. It was not preserved and Tomlinson describes it as insignificant, something like "QWERTYUIOP". This is commonly misquoted as "The first e-mail was QWERTYUIOP". Tomlinson later commented that these "test messages were entirely forgettable and I have, therefore, forgotten them."
At first, his email messaging system wasn't thought to be a big deal. When Tomlinson showed it to his colleague Jerry Burchfiel, he said "Don't tell anyone! This isn't what we're supposed to be working on."

You probably use it every day but how well do you
know your Internet?
Ever wonder how all this foolishness got started in the
first place and why? How big it really is? How many present
users there are? The average time spent on a website?
Here are 21 facts you might or might not want to know
about the Internet.
1. Who coined the phrase 'World Wide Web'?
Tim Berners-Lee in 1990. He's also considered by most
people as the person who started the whole thing rolling.
2. How did the Internet Start and Why?
It all started with the time-sharing of IBM computers in the
early 1960s at universities such as Dartmouth and Berkeley in
the States. People would share the same computer for their
computing tasks. The Internet also received help from Sputnik!
After this Russian Satellite was launched in 1957, President
Eisenhower formed ARPA to advance computer networking and
communication.
Plus, we won't even mention that whole industry where
people show their naughty bits.

In some places such as schools, offices or cafes there are sites like Facebook, Friendster, Youtube and others are deliberately blocked by the admin with a specific reason. But with a little trick, We can access or open the blocked sites. Here are some steps:

Every time we browse the Internet almost all of them typing the URL (Uniform Resource Locator) such as google.com, youtube.com. URL used to distinguish a web address and of course all sites have a URL that is not the same, except that the URL can facilitate internet users to remember the web address on the internet.

Many a time, it becomes necessary for us to write protect our USB flash drive so as to protect it from viruses and other malware programs. Because flash drives are so popular and most widely used to move data between computers, they are the prime target for attackers as a means to get infections spread around the computer world. Also, since USB drive is not a Read-Only Memory (ROM), the data inside it can easily be modified or deleted by malware programs.
But unfortunately, most of the new flash drives do not come with a write-protect feature as the manufacturers wish to cut down the cost of production. Hence, the only way to write-protect your USB flash drives is to enable this feature on your own computer.

5) DirectX diagnosis = dxdiag.exe (Diagnose & test DirectX, video & sound cards)
6) Private character editor = eudcedit.exe (allows creation or modification of characters)
7) IExpress Wizard = iexpress.exe (Create self-extracting / self-installing package)

I did some research and it turns out you can easily add bold text or italics to your Facebook chat by adding small code around it. I guess bold text can help emphasize your Facebook chats, and italics can make your text look different. It’s not really a new font for Facebook chat, but it’s kind of cool.
Here’s the code to make your text italic or bold on Facebook chat .:
Bold text – *surround your text with stars*
Italic text – _surround your text with underscore_
Get it?
Put *stars* around your text to bold it,
and
Put _underscores_ to make it italic!
Enjoy your new bold and italic text in Facebook chat!!!

Well, these aren't just Mozilla tricks. Some of these work in many browsers, some only in some browsers, and some not in the most recent versions of any given browser, etc. Still, I find them fun. See this link for more info.
