Hello everybody, my name is Linux, a computer is a "housekeeper", the daily job is to command the CPU, memory, hard drive, keyboard, mouse, monitor and other equipment up and running in an orderly manner. Figuratively speaking, I am a user to communicate with the underlying hardware bridge. The user can enter commands me, I am responsible for command interpretation, drive hardware equipment, and user requirements.
I was born in 1991, is a standard of 90, my dad is a little-known graduate student Linus Torvalds of Finland. When I was 3 years old (1994), and my dad prepared to officially take me out to see the world, which is published in the official Linux kernel 1.0, so I made a man to set up - a penguin named Tux.
I asked my dad why people gave me this set, he told me: "on behalf of Antarctic penguins, the Antarctic and the world there is a piece of land does not belong to any country that is not part of any commercial Linux company, yes. everyone can share all mankind. "
(Well! My dad this large sub-trotters) To be honest, I do not believe in the slightest my dad said, I think my birth was an accident. As for why? This goes back a long time ago:
Probably my grandfather that era, there is a legend --UNIX, UNIX His father is AT & T Bell Laboratories.
Yes, that developed a lab phone, so the UNIX academic performance is very good. Later, UNIX source code is the use of various universities and laboratories. As the price, these institutions need to pay a license fee to the UNIX his father (that is, AT & T Bell Laboratories).
One day, a team at the University of California at Berkeley UNIX shining model also trained a student - Berkeley UNIX (Berkeley UNIX), name BSD.
Later UNIX growing fame, his father UNIX license fees charged to major institutions have become more sophisticated, Berkeley BSD development that the time has come, who began the BSD and AT & T about the complete exclusion of the code, claiming:
That we will use our home BSD code can, as long as we recognize these achievements Berkeley can be.
This model is known as: code is freely redistributable, that is free to use, free to learn and modify freely distribute, create derivative free version.
In order to better explain my birth, I should also mention a person --Minix, she was born in 1987, a bit like with Unix, was described as a Unix-like computer operating systems based on micro-kernel architecture. Minix's life can be said to be entirely spent in the ivory tower.
Because many of the early university institutions are using Unix, Unix his father but later changed its policy and decided to privatize the Unix source code, which is no longer able to use Unix source code at the university. To professor can teach students practical details of the operating system works in the classroom, we decided not to use any AT & T source code under the premise of developing its own Unix-compatible operating system, in order to avoid disputes on copyright. And with a small Unix (mini-Unix) name, referred to Minix.
Later, users found a loophole Minix, recommended patch perfect, but was refused Minix creator that has maintained its most original style. (Of course, this is something)
And my dad, at first bought a computer of his own, mostly when people use the DOS operating system, his computer is no exception. In order to meet his daily read news and e-mail needs, so he wants to develop one of their own operating system.
Because my father did not like the DOS system on your own computer, he took a fancy to the house next door and well-behaved sister --Minix. So he thought:
Since Minix so great, so steady, that why do not I ported it to a personal computer it?
So my dad read the Unix core, and the core removal more complicated program that will rewrite it to x86 systems above can be applied to general personal computer. Then, I was so in his cock was born. Then my dad generously source code uploaded to the Internet, and this operating system named "Linux", which means "Linus's Minix".
Asked: so naked like people Minix, I put Linux on where?
It's not that I go out everyone would talk quietly: wow, Linux and Unix like.
Have to admit, I really re-implementation of Unix. Because my dad when I create, learn Unix technology and user interface. Any of the other hand, I create my dad at the time also into a lot of unique technology to improve, therefore, form and source code from development to produce the final point of view, I do not belong to AT & T and BSD Unix in style . Strictly speaking, I'm different from another operating system is Unix.
Of course, although I have been Tucao my dad is a big sub-trotters, however, have to say, he really is ingenious in the training mode. From my birth, my dad took me posted online, and publish a post, probably:
I wrote an operating system kernel, but still not perfect, you are free to use and free of charge, it can also help me revise together.
Post issue has aroused strong repercussions, everyone on this had a strong interest.
As to why everyone on the "training" I have such strong interest, shall no longer refer to a person --Richard Stallman (the father of Free Software), he believes that software is the wisdom of all mankind, should not serve as a company.
In the eighties, Richard Stallman launched the free software movement, namely GUN movement, and released the GPL, which got a lot of people. And I was under the GPL, and this way, the hobby programming "dads" in my research we shall not lawsuits.
This makes me grow spent on the Internet under the watchful eye and care of all technical personnel, it can be said to be eating hundreds of meals grew up.
Thus, the super-more people contribute source code to the community, and do not ask us for reward, and they can use me and my achievements. Thus, resulting in a global cultural phenomenon, they put this culture is called - open source.
Therefore, Linux has many versions, but strictly speaking, Linux actually defines a single operating system kernel, the kernel from the kernel.org is responsible for maintaining. Different businesses and organizations on this basis, developed a series of supporting software, packaged and released their "release."
Various releases can be "very different", but it is built on the same foundation. It is because of "dads" continuous efforts and improvements, but also makes me a certain extent has made extraordinary achievements. Proud of 2011, the world's top 500 supercomputers, there are 92.4% (462 units) of the computer I have adopted as the operating system.

Why am I able to achieve such impressive results? This unique qualities with me - has a lot of open source.
Compared with the Windows operating system occupied most of the country, and my source code is publicly available on the Internet, and when users find bugs, bug fixes can be performed directly from the source code level. Therefore, users need to have a lot of code security audit prefer me, I have now been in hot pursuit across the globe.
How, I was not very powerful? Here, I have to thank the pro dad Linus Torvalds, although I always say you're a sub-trotters, but have to say, you have created a miracle of the operating system for the human community.
