When Jiang Chen came out of the office, it was already late at night. Looking at the deep night and the flying snowflakes, thinking of being deserted all day again, Jiang Chen couldn't help burying his chin in his scarf and sighed. He still has some things to do in Wanghai City, and he has to rush back to the new country when he is done. Virtual reality online games are on the way, and his time is not ample.

However, when looking at the second daughter who was holding his arm and had a happy aftertaste on her face, the only little dissatisfaction was also washed away with the snow.

Overnight.

In the early morning of the next day, Jiang Chen came to the community center in winter clothes and on the snow up to his knees. When he was just going to the software development department to find Du Yongkang, he saw this guy take the initiative to find him. Seeing the pile of documents held by Jiang Chen, he immediately complained to Jiang Chen with a bitter face.

"Boss ... Oh no, Marshal, the staff in our department is really not enough. Now, including me, all the people are doing the work of two people. Of course I am not complaining, or I would like to invite you to urge Wang Qing. Can the application staff be approved sooner? "

Seeing that Minister Du is so pitiful, Jiang Chen was also a little unbearable, and could not help speaking out of concern.

"Is it so serious?"

"Otherwise ... no one in our department works without dark circles."

Looking at the pitiful Du Yongkang and glancing at his dark eye bags, Jiang Chen couldn't help but sigh.

In the original software development department, that was really an envy. The whole fish bone base, they are the most relaxed. If the welfare is not bad, I won't say it. I don't have to risk my life. I copy the game code all day long. I don't know how many people want to enter this department!

But it ’s different now. Both internal and external troubles are fixed, and the wars of all sizes are basically over. Those knights with all their military skills have enjoyed the blessing. Either shooting at the training ground all day, or carrying a few guns and driving the car to patrol, standing in front of the ragged refugees, enjoying the envious and respectful eyes.

In contrast, people in the software development department are busy becoming dogs. Credit point payment system, Wanghai communication base station maintenance, market transaction software, recently Chunan also proposed to establish NAC regional network, integrating municipal administration, law enforcement, and tax payment ...

And who will do these things?

Wang Qing thought about it, and the entire base knew that the software development department knew much about computers, so they put these tasks into Du Yongkang's department.

"This is also true of Wang Qing ... I will talk to her later."

After hearing this, Du Yongkang immediately nodded with a smile, "Hey, then you will be done."

"What's so polite." Jiang Chen waved his hand and handed over his plan for developing a VR social platform and online shopping platform.

Looking at Du Yongkang, who has an unbelievable look on his face, Jiang Chen patted his arm with some embarrassment. The task can be slowed down temporarily ... cough, double the overtime pay, and the manpower will be in place as soon as possible. "

Although he sympathizes with his experience, he still has to complete the tasks that must be completed.

However, Du Yongkang, who watched his footsteps astray, left slowly, and Jiang Chen always felt full of guilt in his heart.

Do you want to give some benefits to the code farmers of the Software Development Department? For example, a box of milk and a basket of eggs are sent every week ...

Thinking about it this way, Jiang Chen came to the logistics department and found Wang Qing who was busy checking inventory data.

"It's not that I don't want it, but there is no one to apply for." After listening to Jiang Chen, Wang Qing pushed the glasses on his nose bridge and explained with a wry smile. Computer talents are also quite scarce. As soon as I recruit people, I transferred them to him. "

"What about Refuge No. 27? There should be computer talents?" Jiang Chen asked.

"Yes, there are, but there are almost no computer-based businesses. Experts in these fields basically have research tasks in their hands. If you mobilize them at will, you will lose your way." Wang Qing said.

There are scientific research projects in the body, which is really not easy to mobilize. There is no better way. Jiang Chen had to tell Wang Qing to increase the salary of the software development department staff and post it in the recruitment information of the sixth block. In addition, he also sent a text message to Zhao Chenwu, allowing him to pay more attention to computer talents in the caravans outside the province. Anyone with a test rating greater than C will try to recruit them.

For women, the technical requirements can be relaxed. D and E can also be considered. After all, the whole department is full of male creatures, and Jiang Chen who looks at them feels pitiful for these single dogs who bowed down ...

The main purpose of coming back this time is to put the two plans in the hands of Du Yongkang and take a look at the girls and their men who have not seen for a long time.

After turning around in the community center, Jiang Chen came outside. After some time, he went to the Aerospace Science and Technology Research Institute and found Jiang Lin who was busy in the factory building.

Just a while ago, Jiang Chen had asked him to design a quantum communication satellite, and he did n’t know how he was going now. It happened that there was still some time, and Jiang Chen came here and made a circle.

Seeing Jiang Chen coming, Jiang Lin stuffed his hands with a colleague in work clothes and greeted him.

Stopping at the workbench, Jiang Chen saw the square head and square brain on the round table, and could not help asking, "Is this a quantum communication satellite?"

"Almost, the appearance is like this. The key quantum communication components have not been installed yet. We are still waiting for the news from Refuge No. 27. It is said that there is a small problem in the refrigeration device, and the size does not match and needs to be renewed Design ... How do you look at your expression, seeming disappointed? "Jiang Lin asked unexpectedly while looking at Jiang Chen.

The first thing to say here is that although quantum communication and quantum computers have quantum in their names, they are actually two very different things. The so-called quantum communication refers to a new type of communication method that uses the quantum entanglement effect to transfer information, and is a composite discipline combining quantum theory and information theory. On the other side of the world, this subject has gradually moved from theory to experiment. At the end of the 22nd century, the research on quantum communication has already moved from the military field to the civilian field.

Compared with the fast but "unsafe" Klein particle waves and the gravitational waves with slow research progress, quantum communication technology is undoubtedly more friendly to the people.

The advantages of being difficult to crack are self-evident, especially after the major breakthrough in the research on the transmission of "non-classical information", quantum communication that was originally considered to violate the theory of relativity has also become a reality.

What's the use of super light speed communication? This is very useful!

If nothing else, let ’s talk about the current Internet. Nowadays, every household is connected to the Internet, but they all rely on submarine cables to interconnect. Why has n’t Google ’s global wifi plan been announced for so long before it ’s a little bit quiet? On the one hand, it is because the communication screen is crowded, and the most fundamental reason is to use traditional satellites as the nodes of the network connection, which is technically infeasible!

The synchronous orbital altitude is 36000 kilometers, and the traditional satellite is used to provide wifi service. Regardless of the attenuation of the electromagnetic wave signal, ideally the basic delay is above 500 ping. What is the delay of 500ping? To put it simply, when you play LOL, you may not see your own people.

So, if you use traditional satellites to provide network services, sending an email may be acceptable, making phone calls will be more difficult, so do n’t think about online games.

The Quantum Communication Satellite, which is now in front of Jiang Chen, is such a great thing that can overcome the difficulties that traditional satellites cannot overcome. It is also a communication transit station for virtual reality networks in the future.

Looking closely at the satellite, Jiang Chen touched his chin and said.

"I thought it would look better."

Jiang Lin froze for a while, and laughed, "There is no need to consider aerodynamics in the universe, all shapes are the same. If you need, I can make it into a circle. But the internal components have to be redesigned. "

"No need, that's what I said." Jiang Chen said with a shame.

The cost of building such a satellite is not cheap. I really need to redesign one, and it ’s his own distress. Because these things are simply not used here, Wang Qing of the Logistics Department complained to him about the unreasonable budget allocation of this institute. (To be continued.)
