Google
Believe it or not, the gigantic, ever-growing cluster of servers that power Google's search and other apps runs Linux. Of course, in typical fashion, Google was not content to simply run an out of the box version on its own hardware. Instead, the search giant had its engineers cook up a customized version of Ubuntu referred to within the company as "Goobuntu." Linux is also frequently used internally on desktop machines, beyond its use on Google servers.
IBM
In addition to doing development work on Linux itself, IBM is known to use it internally on desktops and servers. IBM also ran a TV ad campaign in 2006 called "IBM Supports Linux 100%."
Panasonic
Electronics giant Panasonic is another household name company to use Linux in powering some of its operations
Cisco
Cisco Systems, the computer networking and routing giant, switched to Linux after vowing to use Microsoft's Active Directory solution for its servers
Amazon
Online book and electronics retail behemoth Amazon.com is said to "use Linux in nearly every corner of its business",
Wikipedia
Popular online encyclopedia Wikipedia is another staunch supporter of Linux, having switched to Ubuntu in 2008 after a lengthy tenure using Red Hat and Fedora prior to that.
Sony Playstation 3
While Linux is not pre-installed on the PS3, it was designed to allow easy installation of it and Gamespot revealed in 2006 that "Terra Soft Solutions is now making Yellow Dog Linux 5.0 available for download for the PS3."
Mobile Internet Devices
Yet another area Linux has conquered are the mobile Internet devices or MIDs, such as the Nokia’s N800 and N810, in which Intel sees a lot of prospects for the future. They actually run Ubuntu.
Cell Phones
Is that a Motorola RAZR you are using? Or is it a ROCKR? Maybe it’s a T-Mobile G1? Or is it a nokia series? I am sorry, but you are already using Linux in your cell phone. Shocked? Please don’t be. While you have to close all your programs to free up memory on your cell phone in Windows devices, your Linux handset takes care of it automatically, and brings that famous server reliability to your handset
FACE BOOK:
Nothing to get suprised The frame work of facebook is devoloped in "ruby on rails" an open source framework.It means nearly 57 percent of the world's population is depending on open source with out knowing that they are!

WHY MR.VIRUS CANNOT CONQUER THE MIGHTY LINUX.
The following are main reasons why virus have failed to invade the Linux operating system
1. Linux does not execute any file automatically, hence virus cannot execute when we start a program.
2. The kernel of Linux is re-bootable, hence each and every time a fresh configuration is loaded.
3. No virus has been programmed for Linux system. All the viruses are majorly coded to target the windows.
4. Linux provides security by halting auto executable files.
5. Linux has an inbuilt firewall.

EMACSPEAK
To grasp the accessibility benefits of Linux’s text-only interface, a look at Emacspeak should be taken .Emacspeak a speech interface enables visually impaired computer users to work independently and efficiently with the computer.
Emacspeak perfectly exemplifies the leveraging that's possible by making use of Linux's fully developed text-only environment. Emacs is far more than a text editor; over the years, it has acquired so many accretions that it can function quite nicely as a mail reader, calendar and scheduling program, Internet browser, and much more.
Emacspeak gives Emacs the consistent keyboard input design that people with limited vision require, and its consistent, comprehensive implementation of speech synthesis doesn't leave users in the lurch. With Emacspeak, people with limited or no vision can quickly become successful and competent users of e-mail, the Internet, and text-based documents. Emacs can also function as a text-based interface to the bash shell, which means that users can harness the full power of thousands of console mode programs and utilities.

FOSS-WHATS IT?
Most simply, the term "Free and Open Source" means the availability of a piece of Software's Source code. However, there is much more to Open Source than handing out code - it is a set of principles and practices on how Software is written. Software developed with these ideas in mind benefit from many positive aspects of the process, and, properly utilized, can improve the efficiency and impact of many institutions in society. How, you ask? An excellent question - let's explore....
The first and most apparent benefit for most about Open Source Software is the price - or rather, the absence thereof. This makes Open Source products easy to obtain, risk-Free to try for an infinite duration, and eliminates the need for complicated, often frustratingly arbitrary registration procedures that accompany Software licensing. While there are a number of Open Source licenses - the most prevalent of which is the GPL - they are alike in their preservation of Freedom for the user, and their insurance of the Freedom of any "derivative works" which may (and often do) come from an Open Source development model. The user - be it an individual, a non-profit organization, a corporation - is permitted to use the Software in whatever manner desired, to install it on as many different devices as desired, and to modify it however may be desired.
How does this end-user Freedom benefit, say, an educational institution or a city government? This means that Open Source Software, for these groups, is not only virtually Free to obtain, to use, and to keep using - it is also Free from any interests other than those of the organization, and customizable to whatever specific needs may arise. This is a powerful idea - with commercial, proprietary Software, organizations are hindered in so many ways; bound by the profit-driven Software company. Open Source Software is Free from all of this corporate interest - focus is placed on developing Software for the end user, not the financial need of any one entity.

WML
***Wireless Markup Language, based on XML, is a markup language intended for devices that implement the Wireless Application Protocol (WAP) specification, such as mobile phones, and preceded the use of other markup languages now used with WAP, such as HTML/XHTML***
STRUCTURE
"http://www.wapforum.org/DTD/wml_1.1.xml" >
***Wireless Markup Language is a lot like HTML (Hyper Text Markup Language) in that it provides navigational support, data input, hyperlinks, text and image presentation, and forms. A WML document is known as a “deck”. Data in the deck is structured into one or more “cards” (pages) – each of which represents a single interaction with the user.***
***The introduction of the terms "deck" and "card" into the internet and mobile phone communities was a result of the user interface software and its interaction with wireless communications services having to comply with the requirements of the laws of two or more nation***
***WML decks are stored on an ordinary web server trivially configured to serve the text/vnd.wap.wml MIME type in addition to plain HTML and variants. The WML cards when requested by a device are accessed by a bridge WAP gateway, which sits between mobile devices and the World Wide Web, passing pages from one to the other much like a proxy.***

WHAT WEB 2.0 LACKS
***"Web 2.0" does not represent a new version of the World Wide Web at all, but merely continues to use so-called "Web 1.0" technologies and concepts.***
***First, techniques such as AJAX do not replace underlying protocols like HTTP, but add an additional layer of abstraction on top of them.***
***Second, many of the ideas of Web 2.0 had already been featured in implementations on networked systems well before the term "Web 2.0" emerged. Amazon.com, for instance, has allowed users to write reviews and consumer guides since its launch in 1995, in a form of self-publishing. Amazon also opened its API to outside developers in 2002***
***Other critics labeled Web 2.0 “a second bubble” (referring to the Dot-com bubble of circa 1995–2001), suggesting that too many Web 2.0 companies attempt to develop the same product with a lack of business models. For example, The Economist has dubbed the mid- to late-2000s focus on Web companies "Bubble 2.0".***
