Countercurrent 1982

Chapter 1761 Kirin System
The operating system is invisible and intangible, but it is everywhere.It is the soul of the computer and the foundation of the network security of a big country. Without core technology, there is no right to speak; without core technology, there is no way to talk about independent development. With its own operating system, a country can only master its own in the field of information security. The right to speak.

In the early 90s, few people in China paid attention to the development of domestic computer systems. The main reason for this was that at that time, domestic computers mainly used DOS systems, and only new computers were equipped with Windows systems. Computer systems are dispensable to many people.

Another point is that in the early 90s, the Internet had not been introduced in China, and all the computers of government departments were in a state of internal networking, or simply used as a stand-alone computer, usually used to calculate financial storage data and print some related reports. All of this can be done from the DOS system, and people pay more attention to Chinese software and hardware such as Hanka.

In fact, as early as 1983, China had already developed the first Chinese operating system CCDOS. Although the operating system was localized, the core technology was not in its own hands, and the information security of the people could not be guaranteed at all.

For ordinary enterprises, it doesn't matter whether they have a domestic computer operating system, because they need to process relatively few data through the computer, and most of them are for private use. As long as the operating system is smooth, it is completely acceptable.

However, for industries such as national defense, power finance, energy, and education, the security and confidentiality of the operating system become extremely important. If the computers of these departments are blocked by foreign companies, or corresponding leaks occur, the consequences will be disastrous of.

It is precisely because of this that some experts from the Ministry of National Defense first proposed the development of a domestic operating system. In their view, the Internet is developing very fast abroad, and sooner or later it will enter the Chinese market. At that time, if Without our own domestic operating system, we will face various risks.

The plan to develop a domestic computer system was finally approved by the head of the higher department.

In fact, Duan Yun has long had the idea of ​​​​planning to develop a domestic operating system, and has been saving technical talents for this purpose.

And it is the best time to develop a computer operating system at this time.

Because at this time, the operating systems used by computers in the world are competing for hegemony, Windows system and Linux system have not yet come out on top, and Berkeley University's freebsd, IBM's AIX, and Sun's soliris operating system are also used by many users. It is not like the stable pattern of Windows dominating the world in later generations.

In addition, in terms of the kernel, the Mach of the microkernel architecture is on fire, and there is a tendency to start a prairie fire. The macrokernel represented by the Linux system does not show any weakness. Some of these systems are open source, and some are closed source. In the end, which technology will become the world's Sexual dominance has not yet formed a unity.

Even in the face of the best opportunity, Duan Yun is powerless to develop a domestic operating system, because this is not a technical project that can be completed by a single company, even if Tianyin Group is currently the largest private technology company in China.

In later generations, the national 865 plan finally listed the research and development of domestic computer operating systems as a part. It is known as the largest software project since the founding of the People's Republic of China.

At that time, in addition to the National Defense University, ChinaSoft, Inspur, Lenovo, the Institute of Software of the Chinese Academy of Sciences and other top software companies and institutions in the country participated in the project. It was considered the most powerful software "national team" at that time.

However, the research and development of this project is not smooth. Although there are many scientific research institutes and enterprises involved, there are very few people who are actually engaged in the research and development of this project. More than a dozen engineers are determined to develop a domestic independent operating system. After more than half a year of discussion, it was finally decided to learn from the advantages of the four codes to build its own new generation of operating system.

The so-called borrowing from the codes of the four companies, to put it bluntly, is to imitate foreign software companies, piece together some of their technical architectures, and combine them into a brand-new domestic system.

The bottom layer uses the Mich microkernel as a model, the service layer uses the FreeBSD system as a reference, the application layer uses the Linux system as a reference, and the interface is designed after Windows.

This is an extremely complicated structure, full of helplessness and compromises of engineers, their experience, manpower and time are seriously insufficient, so they can only adopt the most stupid way and take the most complicated path.Because of the integration of the technical architecture of four operating systems, the number of kernel codes of only one system is as high as 400 to 500 million lines, a total of nearly 2000 million codes, densely printed on A4 paper can be stacked more than 70 meters high.

Faced with such a huge workload, engineers often stare at the computer for more than a dozen days and nights to type codes, and use the laboratory computer room as their home.After more than two years of hard work, the new generation of China-made operating system has finally been successfully developed.

During the initial interview of Kirin System, it was difficult to find an application platform and unit in China.

At this moment, a turning point appeared quietly.Since CAIC's ticketing system uses foreign operating systems and databases, foreign manufacturers opened their mouths when renewing the contract and offered a price ten times higher than before.Faced with the outrageous price increase of foreign manufacturers, China Civil Aviation Information Group began to seek domestic replacement products.

In this way, the Kirin team has its first potential large-scale customer, but the iron needs to be hardened by itself. If the Kirin operating system cannot cope with the huge amount of transaction data in the civil aviation ticketing system, it is very likely to cause a major accident involving hundreds of thousands of passengers stranded at the airport. .In the face of opportunities and challenges, Kylin's engineer team stationed in the service enterprise, took the computer room as their home, and often spent more than a dozen days and nights in the computer room, carefully solving every problem encountered.After eight years of arduous research, many airlines have used the Kirin operating system, completely getting rid of the constraints of foreign software.

Later, as the government and the public's awareness of information security continued to increase, "Kirin" has spread all over the fields of transportation, finance, energy, and public services.

Later, after more than 10 years of development, the Kirin system finally became mature and stable, making a great contribution to the country's Internet security.
