"What you mean is that this serial number is an irregular and meaningless combination. It is only used to identify the uniqueness of each resident ID card. Once an accident such as loss occurs, a corresponding state is made in the database space. Mark." Ni Guangnan quickly understood what Tang Huan meant.

"That's it." Tang Huan nodded, "For example, the setting of a combination of eight digits and letters, the capacity is 62 to the eighth power, even if the uppercase and lowercase letters'o' which are easily confused with the number '0' are excluded. With such a combination, the available flow is still extremely impressive, enough to deal with loss reporting, renewal, and so on. Moreover, this flow cannot be upgraded by increasing the length."

"With an 8-digit serial number and status labeling, each ID record must increase by at least 9 bytes. Even if only 100 million people apply for the certificate in the initial stage, an additional 900mb storage capacity will be added." Ni Guangnan roughly calculated After a while, not only the eyes are a little straight.

After decades in the original time and space, the hard disk used by personal computers can easily reach hundreds of gigabytes, or even tb. Storage systems in the enterprise field even regard tb as commonplace, but now it is still a stage of careful planning with mb.

Therefore, Ni Guangnan felt that as soon as his upper lip touched his lower lip so easily, two more data items were added. With the additional resource expenditure, whether it is worthwhile is really not a trade-off.

Tang Huan glanced at Ni Guangnan and said that the hard disk head technology is indeed a difficult problem that must be overcome in advance, otherwise the hard disk capacity is less than the gb mark, and the application is always constrained.

"Okay, don't count as a housekeeper. When the resident ID project is really implemented, it is impossible to be free. It is not necessary for you to worry so much. This is not over, we will continue to discuss resident status. This indicates the meaning of the number." Tang Huan waved his hand, intending to continue to expand the topic of resident identity cards.

"After all, different from ordinary information processing systems, the design of the resident ID card needs to be more long-term. Therefore, only two digits are used to record the year. The seemingly redundant resources saved now will be carried out when the year 2000 arrives. Compared with the resource cost required for system upgrade, it may not be cost-effective. In addition, the most important point is that the last three digits of the sequence number provide insufficient information space, which will inevitably cause the duplication of the resident ID number. If you don’t believe it, just do it. Go to the field to collect samples for investigation."

Ni Guangnan quickly recorded the main points that Tang Huan said. Then he sighed, "How come this plan is so full of errors and omissions under your comments!"

"Because this is the sad summary of the grassroots running and breaking their legs in the original time and space." After murmured to himself, Tang Huan said without embarrassment: "This is the project experience, and it can't be learned by others casually."

"Indeed." Ni Guangnan, who originally admired Tang Huan's technical attainments very much, felt that the reason was logical, so he nodded convincingly.

Tang Huan pondered for a moment. "Nowadays, there is still a big controversy over the business of scientific and technological personnel in China. You, a typical person, should also pay attention to protecting yourself. You can't be too sharp, so while giving advice, your rectal temper is also If you want to collect it, you can't forget to unite people."

Seeing Ni Guangnan’s humbly teaching, Tang Huan smiled, “In fact, coding is the most basic and most important link in the country’s informatization project. Once it is done, the entire system runs smoothly and efficiently. It saves resources; otherwise, it wastes money and costs. In order to save face project. Individuals must have resident ID cards, and companies must have similar certificates, but they will have more than one mother-in-law in charge. Such as industry and commerce, taxation departments, etc. If the information systems of these management departments are self-contained, even the most If the basic codes cannot be interoperable, it is actually an island of information at the national level."

Having said that, Tang Huan smiled, "You can discuss more in the report. I hope you can avoid detours."

It can be said that Tang Huan has always tried to keep a low profile in mainland China, and his technical and other vocalizations are usually under the guise of Ni Guangnan and others.

Tang Huan hopes to make the project of resident ID card perfect at one time and make it convenient for the public. This is why he tried so hard to discuss with Ni Guangnan.

Seeing that the other party fully understood his intentions, Tang Huan let out a sigh of relief, inevitably happy in his heart, this can be regarded as a merit.

In addition to interrogating these two big projects that have already been obtained and the employer is the country, Tang Huan mainly focuses on Zhongguancun, a potential site that will surely develop in the next few years.

In fact, the prelude to the market-oriented and self-employed entrepreneurship of Zhongguancun's scientific and technological personnel began as early as 1980. On October 23 of that year, Chen Chunxian, a researcher from the Institute of Physics of the Chinese Academy of Sciences, who had visited Silicon Valley twice before, and 6 scientific and technical personnel, with the support of the Yanjing Municipal Science and Technology Association, established the Advanced Technology Development of Beijing Plasma Society Service department.

This is the first private science and technology institution in Zhongguancun that was founded by science and technology personnel and provided paid technical services to market demand.

These private technology enterprises have implemented a series of experiments and explorations of business management systems represented by self-raised funds, free combination, independent operation, and self-financing, that is, the "four-self principle", making the enterprises become the main players in the market.

However, the “business” behavior of scientific and technological personnel has also been controversial, and this can be regarded as an unavoidable feature of the times.

At the end-of-year networking gatherings of all sizes, Tang Huan once again discussed with Chen Chunxian, the pioneers of China’s Silicon Valley, how the high-tech industry of it can adapt to the development of the country’s conditions, and also paid special attention to collecting the original time and space. The “two links and two seas” that will soon surface-Stone Company, Xintong Company, Kehai Company, Jinghai Company, and the relevant people of these four representative leading enterprises in Zhongguancun, only But they are still somewhat unknown to the outside world.

It is no exaggeration to say that Tang Huan has been enthusiastically sought after on these occasions. One of the major reasons is that the "Technology Development Fund" he set up-this piece of Tang Seng meat to support the development of social projects is really too sophisticated Attractive.

Any unit or individual can apply for the use of this fund, which is actually equivalent to the popular venture capital in Silicon Valley in the United States, but it doesn't use such an ungrounded foreign name.

At the current stage, with a capital of 30,000 to 50,000 yuan, private technology companies can be opened. With the strong financial resources of the angel investor, the boss of Tang Da, he can almost respond to requests, but he is not so taken advantage of.

after all. Tang Huan still needs to take into account his identity as a businessman. Even if he is to be a spoiler, the money thrown out has to be heard, for those who beg to come. It is inevitable to pick and choose. For example, those repetitive projects that still want to engage in Hanka are simply ignored.

Even though many people returned in disappointment, Tang Huan still received an endless stream of applications, which is also related to the current environment.

After the Cultural Revolution. National leaders hope that the Chinese Academy of Sciences will make some achievements that can serve the national economy as soon as possible.

However, scientists think the opposite. They believe that due to the 10-year delay by the Cultural Revolution, the distance between China's basic science and the world's advanced level has widened, so it is necessary to strengthen basic theoretical research first.

Even after the leaders had a discussion with some scientists and proposed that scientific research should serve economic construction, the reaction of the scientists was still rather indifferent.

These scholars can stick to their own principles, but the Chinese Academy of Sciences' management organs are more anxious, because if there are no results for economic construction, the state's funding for the Chinese Academy of Sciences is likely to be cut. At that time, we will fall into a vicious circle.

Therefore, the management of the Chinese Academy of Sciences is very willing to see the scientific and technological personnel under the rule go to the market, and are constantly promoting this matter.

Welcoming and sending to the middle, finally a well-known figure appeared in front of Tang Huan, Wang Hongde, the founder of Jinghai Company in the original time and space.

"If I can get support from Mr. Tang, I don't have to wait until the Chinese New Year, I am willing to give up public office and start a business." After the greeting, Wang Hongde's tone was sonorous and powerful.

Heard this. Tang Huan couldn't help being a little curious, "To tell the truth, it's really rare for Wang Gong to make such a decisive statement."

"No way. It's the reality that forced me to choose this way." After a wry smile, Wang Hongde answered frankly.

Wang Hongde is the engineer responsible for the construction of the computer room in the computing institute. His position is the group leader of the power supply and air-conditioning system in the fourth research room of the computing institute. But now he has been suspended and is under investigation because of the educated youth club incident.

The squeamishness of mainframe computers is well known. It needs temperature, humidity, anti-interference, purification, grounding system and so on.

Units that have bought these equipment have to build a "chicken coop" for it, but there are still large gaps in the field of domestic computer room equipment technology research, so they have come to calculate the problems related to computer room construction. To assist in the design and development of computer anti-interference systems, power supply systems, and air-conditioning systems, Wang Hongde is an expert in this area.

Counting all the educated youth clubs established to solve the problem of educated youth employment, Wang Hongde, as the agency’s consultant, introduced them to many computer room projects.

At this stage, the employment situation of educated youth is very serious, and the state has even introduced a policy for this. If 60% of the employment ratio of a unit is educated youth, then business tax will be exempted.

In order to enjoy this treatment, many units deliberately use various methods to take advantage of the loopholes, such as giving 20 yuan a month to the educated youth, and the other party does not have to go to work. The unit just makes up for this loss in order to support this labor ratio and save the tax. came back.

The educated youth club of the Computing Institute is mainly composed of children of professors and experts. After returning to the city, they can only earn a meager income from heavy work such as moving bricks, transporting sand and gravel, and doing cleaning.

Wang Hongde, who wanted to help these educated youths, organized a training class, where he designed the equipment in the computer room, let the computer lab produce it, and then instructed the members of the educated youth club to assemble.

In this way, it has not only promoted the technology, verified the application prospects of large-scale computer room technology, but also saved the country's foreign exchange and improved the living conditions of the educated youth.

At this stage, the computer boom is surging across the country, so the benefit of the educated youth club is very impressive, earning more than 600,000 yuan a year, and the monthly salary of the educated youth has risen from 20 yuan to 90 yuan, but as a consultant for the educated youth agency Wang Hongde has never taken any money.

Supporting educated youth clubs in technical work and serving the society has become a sensation. In particular, the amount of more than 600,000 yuan is astonishing at present.

As a result, Wang Hongde not only did not benefit personally from this, but was also knocked out of the dust, resulting in a "stop working and accepting inspection".

At the same time, in order to find out whether he has committed economic crimes here, the Haidian District Administration of Industry and Commerce investigated him under the pretext of "illegal business and speculation." The discipline inspection departments of the Chinese Academy of Sciences and the Institute of Computing Technology also sent people to investigate.

In this regard, Wang Hongde's grievances can be imagined. In his view, he not only contributed to the educated youth career, but also brought huge profits to the unit. It is not an exaggeration to say that it is the best of both worlds, but it is so distrusted by the unit.

At this point, Wang Hongde had a retreat in his heart, and he didn't want to stay in the computing office anymore.

In addition, Wang Hongde also considered that he was 46 years old, and he might not do much academically. At the same time, he saw that the current computer room project has a huge market.

If you seize this opportunity, leave the computing office, jump out of this unpleasant environment, and set up a company, you can just do a good job and achieve your own business.

Wang Hongde's current state can be summarized as "cannot want to do something, but cannot bear it."

While he was in a fierce ideological struggle ~lightnovelpub.net~ he was indecisive, someone recommended Tang Huan, an angel investor, and bluntly said that the other party has strong financial resources, cooperates with the Chinese Academy of Sciences, and has relatives working here. You can be regarded as a trustworthy person who knows the basics, so it is better to see if you can find an opportunity for entrepreneurship.

After hearing what happened to the other party, Tang Huan looked at the depressed counterpart, smiled faintly, poured a cup of tea and handed it over, "Wang Gong, logically speaking, you are older than me, and I have no right to help you. But I still can't help but want to say that the times are changing, and the individuals in it should work hard to look forward."

"What you said makes sense." Wang Hongde nodded calmly, "I have the intention to start a business, but I can't find the source of the start-up capital."

"It doesn't matter, you have found me here. Naturally, there will be a solution." Tang Huan waved his hand in relief, and muttered to himself, aiming at the achievements of the original time-space Li Kehai Company, one of the four giants in Zhongguancun. I will not hesitate to shoot. (To be continued.)
