"What you mean is that this serial number is an irregular and meaningless combination, just used to identify the uniqueness of each resident ID card, and in the event of an accident such as loss, it will be marked with a corresponding state in the database space." Ni Guangnan quickly understood what Tang Huan meant.

"That's it." Tang Huan nodded, "For example, the setting of the combination of eight digits and letters, the capacity is 62 to the eighth power, even if you exclude the combination of the upper and lower case letters 'O', which is easy to confuse with the number '0', the flow available for use is still extremely considerable, enough to deal with the situation of loss reporting, card replacement, etc." And this flow is not impossible to upgrade by increasing the length. ”

"The 8-digit serial number, plus the status annotation, will add at least 9 bytes to each ID card record, and even if only 100 million people will apply for the certificate at the beginning, an additional 900MB of storage capacity will be added." After Ni Guangnan made a rough calculation, not only did his eyes straighten a little.

In the original time and space, decades later, the hard disk used in personal computers alone can reach hundreds of gigabytes casually, or even terabytes, and storage systems in the enterprise field regard terabytes as commonplace, but now it is still the stage of careful planning with MB.

Therefore, Ni Guangnan felt that as soon as the upper lips touched the lower lips so easily, two data items were added, and it was really difficult to weigh whether it was worth it or not with this additional resource expense.

Tang Huan glanced at Ni Guangnan a few times, and said that the head technology of the hard disk is indeed a difficulty that must be overcome in advance, otherwise the capacity of the hard disk is only the GB mark, and the application is always constrained.

"Alright. You don't have to be a housekeeper to calculate, when the resident ID card project is really implemented, it can't be free. There's no need for you to worry so much. That's not all, let's move on to the explicit meaning of the national ID number. Tang Huan waved his hand, intending to continue to expand the topic of resident ID cards.

"After all, unlike ordinary information processing systems, the design of resident ID cards should be long-term. So, just two digits to record the year, the seemingly redundant resources that have been saved now, and the year 2000 has arrived. The resource overhead required to upgrade the system may not be cost-effective. Also, there is the most important point. The sequence number of the last three digits does not provide enough information space, which will inevitably lead to the duplication of resident ID numbers. If you don't believe me, you can go to the field to collect samples and investigate. ”

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

"Because this is a sad summary of the grassroots running and breaking their legs in the original time and space." After Tang Huan muttered to himself, he said unashamedly: "This is the project experience, not something that others can learn casually." ”

"That's true." Ni Guangnan, who originally admired Tang Huan's technical attainments very much, felt that this reason was logical, so he nodded again and again convincingly.

Tang Huan pondered slightly, "There is still a lot of controversy in China about the business of scientific and technological personnel. You, a typical person, should also pay attention to protect yourself and not be too sharp. So while giving advice, you should also put away your rectum temper, and you can't forget to unite people. ”

Seeing that Ni Guangnan was humbly taught, Tang Huan smiled, "In fact, in the country's informatization project, coding is the most basic and important link, and if it is done well, the whole system will run smoothly and efficiently, saving resources; On the contrary, it will cost the people and money, and it will become a face-saving project. Individuals must have resident ID cards, and similar documents are indispensable for enterprises, but there will be more than one mother-in-law in charge of affairs on their heads, such as industry and commerce, tax departments, etc. If the information systems of these management departments are self-contained and cannot communicate even the most basic codes, they will effectively be information islands at the national level. ”

Speaking of this, Tang Huan smiled again, "You can discuss it more in the report, I hope there will be fewer detours." ”

It can be said that Tang Huan has always tried to keep a low profile in Chinese mainland, and his voice in terms of technology and other aspects is generally stopped under the pretense of Ni Guangnan and others.

The resident ID card project, Tang Huan hopes to achieve perfection at one time and make it convenient for the public, so he discussed it with Ni Guangnan so painstakingly.

Seeing that the other party fully understood his intentions, Tang Huan breathed a sigh of relief, and couldn't help but be secretly happy in his heart, this can be regarded as a merit.

In addition to asking about these two big projects that have already been handed over and the employer is the state, Tang Huan mainly focuses on Zhongguancun, a potential territory that will surely develop in the next few years.

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

This is the first private science and technology institution in Zhongguancun area that was independently founded by scientific and technological personnel and provided paid technical services for market demand.

These private science and technology enterprises have carried out a series of experiments and explorations in the operation and management system of enterprises, represented by the "four-self principle" of self-raising funds, free combination, independent operation, and self-responsibility for profits and losses, so that the enterprises have become independent market players.

However, the behavior of scientific and technological personnel "doing business" has also been controversial, which can be regarded as an unavoidable feature of the times.

At the year-end gatherings of all sizes, Tang Huan not only discussed with Chen Chunxian, the pioneers of China's Silicon Valley, how can the high-tech industry of IT adapt to the national conditions and develop in a down-to-earth manner, but also paid special attention to collecting the "two links and two seas" that would soon surface in the original time and space -- Sitong Company, Information and Communication Company, Kehai Company, Jinghai Company, and the relevant people of these four very representative leading enterprises in Zhongguancun, but they are still a little unknown to the outside world.

It is no exaggeration to say that Tang Huan has been enthusiastically sought after on these occasions, and one of the reasons for this is that the "Technology Development Fund" he set up - this piece of Tang monk meat to support the development of projects in society - is so attractive.

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

The current stage. With a capital of 30,000 or 50,000 yuan, a private technology company can be opened, and with the strong financial resources of Boss Tang, an angel investor, he can almost respond to requests, but he is not so wronged.

After all, Tang Huan still needs to take care of his identity as a businessman, even if he wants to be a fortune boy. The money thrown out also has to be heard, and it is inevitable that those who come to the door will have to be picky. For example, those repetitive projects that still want to engage in Hanka are simply ignored.

Even if many people are disappointed, Tang Huan still receives an endless stream of applications, which is also related to the current environment.

After the end of the Cultural Revolution. The state leaders hope that the CAS will produce some achievements that can serve the national economy as soon as possible.

But. Scientists think the opposite, they believe that due to the 10-year delay of the Cultural Revolution, the distance between China's basic science and the world's advanced level has widened a lot, so it should first strengthen the research of basic theories.

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

These scholars can stick to their own principles, but the management organs of the Chinese Academy of Sciences are more anxious, because if they cannot produce results that serve economic construction. It is very likely that the state's funding for the Chinese Academy of Sciences will be cut, and then it will fall into a vicious circle.

So. The management of the Chinese Academy of Sciences is very willing to see the scientific and technological personnel under its rule go to the market, and they are constantly pushing for this matter.

ushered in the send-off, and finally a famous 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 my public office and start a business." After the greetings, Wang Hongde had a sonorous and powerful tone.

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

"No way, this is also the reality that forced me to choose this way." Wang Hongde smiled bitterly and replied frankly.

Wang Hongde is an engineer in charge of the construction of the computer room in the Computing Institute, and is the leader of the power supply and air-conditioning system team of the Fourth Research Laboratory of the Computing Institute. But now he has been suspended and is under investigation because of the Educated Youth Society incident.

The squeamishness of the mainframe computer is well known, and it requires temperature, humidity, anti-interference, purification, and grounding system.

The units that have bought these equipment have to build a "chicken nest" for it, but there is still a large gap in the field of equipment technology research in the domestic computer room, so they have come to the calculation institute to consult about the construction of the computer room. In order to assist in the design, research and development of computer anti-jamming systems, power supply systems, and air-conditioning systems, Wang Hongde is an expert in this field.

Wang Hongde, as a consultant of the Society, introduced a lot of work to the computer room project.

At this stage, the situation of employment of educated youths is very grim, and the state has even issued a policy for this purpose, if 60 percent of the employment ratio of a unit is educated youth, then the business tax will be exempted.

In order to enjoy this treatment, many units deliberately use various methods to exploit loopholes, such as giving 20 yuan to educated youths every month, and the other party does not have to go to work.

The Educated Youth Club of the Institute of Computing, whose members are mainly children of professors and experts, can only earn a meager income after returning to the city by carrying bricks, carrying sand and gravel, doing heavy work such as cleaning.

Wang Hongde, who wanted to help these educated youths, held a training course, and he designed the equipment in the computer room, let the computer institute factory produce it, and then instructed the members of the Educated Youth Club to assemble it.

In this way, it not only popularizes the technology, verifies the application prospect of large-scale computer room technology, but also saves foreign exchange for the country, and improves the living conditions of the educated youth.

Because at this stage, there is a boom in computers across the country, so the benefits of the Educated Youth Society are very considerable, earning more than 600,000 yuan a year, and the monthly salary of the educated youth has risen from more than 20 yuan to 90 yuan, but Wang Hongde, who is a consultant of the Educated Youth Society, has not taken a penny.

Supporting the Educated Youth Society to engage in technical work and serve the society has become a sensational news. In particular, the amount of more than 600,000 yuan is very staggering at present.

As a result, Wang Hongde not only did not benefit from this, but was also beaten into the dust and ended up with a "stop working and accept inspection".

At the same time, in order to find out whether he had committed economic crimes here, the Haidian District Industrial and Commercial Bureau investigated him in the name of "illegal business operation and speculation," and the discipline inspection departments of the Chinese Academy of Sciences and the Institute of Computing Technology also sent people to investigate.

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

At this point, Wang Hongde had a retreat in his heart and didn't want to stay in the computing institute any longer.

In addition, Wang Hongde also considered that he was 46 years old and might not do much in academics.

At the same time, he also 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 go out to set up a company, you can do a great job and achieve your own career.

Wang Hongde's current state can be summarized as "I can't do it, I can't bear it".

Just when he was fighting fiercely in his mind and was undecided, someone recommended Tang Huan, an angel investor, to him, bluntly saying that the other party has strong financial resources, has a lot of cooperation with the Chinese Academy of Sciences, and has relatives working here, so he can be regarded as a trustworthy person who knows the roots, so it is better to see if he can find an opportunity to start a business.

After listening to what happened to Wang Hongde, Tang Huan looked at the depressed other party, smiled faintly, poured a cup of tea and handed it over, "Wang Gong, it stands to reason that you are older than me, and I am not qualified to explain you." But I still can't help but want to say that the times are changing, and it is better for individuals in them to try to look forward. ”

"You have a point." Wang Hongde nodded calmly, "I have the heart to start a business, but I can't find a source of start-up capital." ”

"It's okay, you've all found me here, and there will naturally be a solution." Tang Huan waved his hand in relief, and at the same time muttered to himself in his heart, he would not hesitate to make a move against the achievements of the original time and space Li Kehai Company, one of the four giants of Zhongguancun.
