The unparalleled talent of the country started from Harbin Institute of Technology

Chapter 128, Four Characteristics of the New Year Red Envelope Courtyard Near the Friendship Hotel
In the office of the Institute of Computing Technology, Wang Duoyu looked at Shan Yunbo and the others with a smile, and nodded to agree to their request.

If you want to learn functional programming, the most basic requirement is to have a high mathematical talent, especially in the study of functions. It cannot be too bad, otherwise, forget it.

"Team Leader Wang, you're saying that in functional programming, data is immutable, right?"

At this time, Shan Yunbo and the other two were extremely curious about knowledge.

If it were before, Shan Yunbo and the others might not have such a strong desire for knowledge, but now several months have passed, and Shan Yunbo and the others have long been convinced by Wang Duoyu.

Previously, Shan Yunbo and Chu Yuheng went on a business trip to Harbin Institute of Technology and witnessed Wang Duoyu's programming speed. Blind typing is not something that ordinary people can do.

Besides, Wang Duoyu completed four MB of programming in just two days. This speed is simply unbeatable.

This time, Shan Yunbo and the other two came on their own initiative to ask Wang Duoyu for help in guiding functional programming, rather than being urged by others.

Chu Yuheng was very stubborn. He didn't come along and was even reluctant to get involved in functional programming. Perhaps he was just a rather arrogant person.

“Yes, that’s the characteristic of functional programming, because once created, it cannot be modified.”

Wang Duoyu nodded and said:
"This actually helps reduce errors in the program because there is no need to worry about data being accidentally modified during program execution."

Shan Yunbo and the other three nodded in confusion. They didn't know what impact this feature would have on the future.

They were the first group of students to learn functional programming, and since this was the first time Wang Duoyu introduced this type of programming language to others, it was normal for Dan Yunbo and the others not to understand it.

"Team Leader Wang, why do we need to use higher-order functions? If that's the case, doesn't it mean that future programmers will need to have a high talent for mathematics? Where can we find so many college students with good mathematical talent?"

Shan Yunbo didn't quite understand the question raised by Chen Ze, who was standing next to him, but there was no doubt that if this was true, then wouldn't anyone be able to program in the future?

Wang Duoyu glanced at the other party and said:
"First, let me explain why. Functional programming allows you to pass functions as parameters to other functions or return functions from one function to another, which greatly increases the flexibility and reusability of your code."

"Secondly, functional programming is the future. It will be widely used in many professional and specific fields. For example, in scenarios that require highly reliable, easy-to-understand and testable code, functional programming provides a very effective solution."

"So, from this we can see that although functional programming is the future, its demand will increase slowly, and it's unlikely to increase significantly all at once."

"Did you read the news about the reform and opening-up conference last December? We have already begun reform and opening-up. In other words, from now on, our country's economy will take off, but this will take time, and the specific scenarios or professional fields that require functional programming will definitely not appear immediately."

"In other words, the demand for talent is not so great all at once."

"There are very few college students in our country right now, right? But what about a few years from now? In 1977 and 1978, the country enrolled nearly 670,000 college students. From now on, the annual enrollment figure is estimated to be 300,000 to 400,000."

"So, as time goes on, college students will become less and less valuable. Just look back at history and you'll see."

What happens when the Siberian cold wind passes through?
In addition to other factors, the most important reason was that there were too many young people in society at that time, but there were simply not enough jobs available in the city, which led to an increase in the number of unemployed vagrants and caused certain troubles to public security.

At that time, college students could indeed be assigned jobs, but from the early 1950s, college students were assigned to good units such as ministries and commissions. By 1965 and 1966, they were directly assigned to ordinary leadership positions in ordinary factories. Could the treatment be the same?

There's a world of difference!
In the original time and space history, after 1998, the policy of no guaranteed job placement began to be implemented on a large scale, and the vast majority of graduates have achieved self-employment.

Therefore, in the future, academic qualifications will only depreciate, and there will be more and more talented people.

Chen Ze's worries are not without reason, but they are too groundless.

After listening to Wang Duoyu's explanation, Chen Ze, Shan Yunbo and Zhang Bin all nodded thoughtfully. They might not be able to fully understand it, but it was enough for them to know that such a thing existed.

The side-effect-free feature is straightforward. It means that functions in functional programming do not depend on any state of the external environment or modifiers. This means that the result of each function call depends only on its input parameters, making the code easier to understand and test.

Zhang Bin and the others did not ask much about this point, but Chen Ze and the others specifically asked about recursion.

"Recursion is a core concept of functional programming. Didn't I say that this morning?" Wang Duoyu looked at the three of them with a slightly helpless expression.

After a pause, he continued:

“Because data is immutable, functional programming often relies on recursion rather than loops to solve problems. Recursion is actually a concise way to express complex calculations.”

Before he could finish, someone else came to the door. It was Director Feng Kang.

After Feng Kang arrived, Wang Duoyu took the opportunity to send Chen Ze and the other three away. He originally came to the capital to solve the problem of the Computing Institute. After that, he thought about solving the problem of the courtyard house.

But now Feng Kang has come to find me, and I’m afraid the time will be delayed again.

"Duoyu, long time no see, happy new year."

When he saw Wang Duoyu, Feng Kang smiled widely, took out a red envelope from somewhere, and stuffed it into the hands of Wang Duoyu.

In fact, this red envelope was the one he specifically asked Xia Peisu for when he went to see him just now.

He has money in his pocket, but there is no red envelope.

"Director Feng, what are you doing? I can't accept red envelopes at my age anymore."

When Wang Duoyu saw the red envelope, his eyes widened and he quickly pushed it back.

My goodness, if he took the other party's red envelope, it would feel like he was receiving a red envelope from an elder, which made him a generation inferior to the other party.

Although Feng Kang was born in 1920 and is now 59 years old, it is normal for him to be a generation older than Wang Duoyu.

But Wang Duoyu’s elder brother Wang Shoucheng is also 58 years old this year, so they are of the same generation.

And looking at this red envelope, there seems to be quite a lot of money in it. Wang Duoyu is not short of money, so it is even more impossible for him to accept the other party's red envelope.

"Here, Comrade Duoyu, I have something to talk to you about."

Feng Kang leaned closer to him and whispered.

However, it was heard by Chen Ze and the other two who had not left yet. Who made the office so quiet?

Shan Yunbo and the other three hurriedly fled the scene, but after leaving, their faces were filled with amazement.

Of course they knew Feng Kang, and had even attended Director Feng's courses before.

But they never expected that even Feng Kang would come to Wang Duoyu for help. How powerful is the latter?

"No, Director Feng, I really can't accept this red envelope," Wang Duoyu said, still declining.
"I still receive a monthly salary from the Institute of Mathematics."

"The Institute of Mathematics is the Institute of Mathematics, and I'm in the Computing Center. They're two different things."

Under Feng Kang's repeated insistence, Wang Duoyu was forced to accept the red envelope.

It is not easy for the other party to ask him for help. After hearing this, Wang Duoyu said that it is definitely not possible in the next two days and he can only help the other party the day after tomorrow.

However, Feng Kang said it didn't matter, as long as people came.

Feng Kang even reminded him, "Comrade Duoyu, why don't you stay in the capital? You have to come to the capital to give a report in April anyway, right? It's so troublesome to run back and forth now."

Wang Duoyu didn't think much about it and shook his head to refuse.

There is still more than a month left until April, which seems too long.

Perhaps if he stayed here for half a month, Liu Deben would probably come to the capital to kill him.

Besides, he came to the capital this time just on a business trip and didn't bring many books with him, so he wouldn't stay in the capital for long.

In the evening, in the guesthouse, Liu Xiaoli told him about her plan to look for the courtyard house today.

The current transactions of siheyuans are not fully liberalized, but there is no problem with private siheyuan transactions. However, it is basically impossible to find a suitable siheyuan in the city.

why?
Because what Wang Duoyu wanted to find was an independent courtyard house, and it had to be one that was uninhabited.

However, even before the 1960s, the area within Beijing's Second Ring Road was already overcrowded. Starting in 1958, many private courtyard houses had been rented out by the subdistrict offices and other relevant departments, replacing empty units with rentals. Furthermore, twenty years had passed, and Beijing's population had grown from 6.6 million to over 8 million.

In the past one or two years, a large number of educated youth have returned to the city. There are now at least 400,000 unemployed educated youth in Beijing, and there are definitely not enough houses in the city.

Therefore, it is almost impossible to find a suitable courtyard house within the Second Ring Road.

Of course, Liu Xiaoli didn't go to the Second Ring Road to look for a house, but she found a fairly suitable courtyard house near Zhongguancun.

"Really? Then let's go check it out tomorrow."

Wang Duoyu made up his mind. He had time tomorrow, and he had to settle the matter of the courtyard house tomorrow, otherwise he would have to stay in the capital for a while. Liu Xiaoli was also anxious to return to Jiangcheng, so she nodded and agreed.

The next day, Wang Duoyu and Liu Xiaoli arrived at the courtyard house.

The environment here is pretty good, and there are foreign-related units just a few dozen meters away. No wonder it has been preserved.

The current owner of the courtyard house is an old man named Zhang. When he saw Wang Duoyu and Liu Xiaoli, he felt a little disgusted.

"Hey man, do you have money? If you don't have money, don't come here to make trouble."

Uncle Zhang was right to be unhappy, because the streets of Beijing were full of unemployed young people, and Wang Duoyu looked like a young man in his early twenties. How could he be rich?
His courtyard house is just a courtyard. Although it is not big, it will cost at least a few hundred or two thousand yuan.

Not to mention young people like Wang Duoyu, even older people may not have so much money.

"Hey, sir, are you looking down on me?"

Wang Duoyu was not unhappy, but the other party looked down on him so much that he would definitely have to have a good talk with him later.

"I'm not looking down on you. The streets are full of unemployed young people right now. You must have just returned to the city not long ago. Where did you get the money?"

Uncle Zhang looked at Wang Duoyu again and raised his doubts.

"Don't worry about where my money comes from. It's absolutely legal and compliant." Wang Duoyu retorted. The old man, who had hit a snag, fell silent and pointed to the yard and said:
"Okay, you guys go take a look and tell me when you're done. If the price is acceptable, then go to the Housing Authority to handle the formalities."

At this time, the old man had no urgent intention to sell the house.

Seeing this, Wang Duoyu didn't bother to pay attention to the old man. Under the guidance of Liu Xiaoli, he began to visit the courtyard.

Although this is a courtyard, it is a quadrangle courtyard built in the Republic of China, so its area is relatively large. The courtyard alone is nearly 400 square meters, which is much larger than the average quadrangle courtyard.

There are five rooms in the north house, two rooms in the east and west wing rooms, and four rooms in the south back house.

The layout of facing south is perfect and in line with the traditional Chinese aesthetic.

There are also jujube trees, pomegranates, and some flowers and plants planted in the yard, which are well taken care of by Mr. Zhang.

The master bedroom is quite spacious and bright, and the east and west wing rooms are equally spacious. After all, the yard itself is very large, so the house certainly does not occupy a small area.

After seeing the house, Wang Duoyu really liked it. A house like this is much better than living in a guesthouse.

"Hello, uncle, how did you manage to preserve such a nice house?"

In the main room, Uncle Zhang, who was half lying on a recliner, glanced at Wang Duoyu and said proudly:
"Have you finished reading it? Do you want to buy it?"

"Yes, but your offer yesterday was too high. If it were 1,800 yuan, I could make the deal with you right now."

"Do you really have so much money?"

At this time, Uncle Zhang immediately sat down, stared at Wang Duoyu, and confirmed again.

Seeing this, Wang Duoyu took out a wad of banknotes from his messenger bag and said:
"Look, sir, here's a thousand dollars I just took out from the bank today!"

After seeing the money, Mr. Zhang's attitude changed 180 degrees. He smiled and introduced himself to Wang Duoyu enthusiastically.

The old man did not bargain with Wang Duoyu, but introduced the situation of this courtyard house. Wang Duoyu and Liu Xiaoli listened, but felt that he was bragging about his products.

"I'm from the Republic of China, and I've experienced all sorts of chaos and turmoil. As early as the 1950s, I already felt something was wrong."

"When I secretly bought this house, my wife didn't agree, and even my sons were not happy about it."

"But they don't know that this house is right next to the Friendship Hotel and is surrounded by foreign-related organizations."

"Over the years, I've come to understand that no matter what dynasty or era, as long as foreigners are involved, rules and courtesy must be followed. This isn't about being a great country, right?"

"The reason I've been able to live peacefully until now is because of two words: caution!"

Wang Duoyu really wanted to interrupt the other party, what cautiousness? It’s obviously just cowardice!
"The courtyard is right next to the Friendship Hotel, and my workplace before retirement was also a foreign-related unit. Thanks to these, I've managed to survive without any major problems until now."

"But it's such a pity. I planned all my life, but in the end, I lost my spouse and my son."

"Luckily, I still have a son who went abroad before liberation. He has written to me now and is coming to take me to live abroad."

When Uncle Zhang talked about this, his face was full of pride.

After hearing what the other party said, Liu Xiaoli was also very curious and yearning, so she asked a few more questions.

With someone to support him and still willing to listen, Uncle Zhang became even more excited and even stood up to find some letters and photos from the room.

"This is my son, this is his daughter-in-law, and this is my eldest grandson"

The old man was very proud because his son came back once before the Spring Festival. During the Spring Festival, he did not have time to deal with the house matters, and his son also needed to go through the procedures if he wanted to take him away.

So I have been busy with these things recently.

"Uncle, I really envy you. You can live abroad. Did your son say which country it is?"

Liu Xiaoli said with emotion, her eyes full of envy.

Her behavior is very consistent with the cognition of most people in this era, because foreign countries must be free.

Although everyone usually criticizes the corruption of capitalist society and shows disdain on their faces, in fact, they are really envious in their hearts.

"America!" Uncle Zhang said proudly. He must have forgotten that he must have called the American Empire a son of a bitch before.

"Look at this photo. This is where my son works in the United States. He said it was a certain street, but I forgot."

Following the photo that Uncle Zhang pointed to, Wang Duoyu recognized it at a glance. Liu Xiaoli just looked at it in surprise and envy, she didn't know.

"This is Wall Street, a financial street in New York City. The building behind it should be the Empire State Building."

Hearing Wang Duoyu's words, Uncle Zhang and Liu Xiaoli looked at him in surprise, especially Liu Xiaoli, who asked curiously, "How do you know all this?"

"Talk less, read more books and newspapers, and you will naturally learn it."

Wang Duoyu responded, then looked at Uncle Zhang and asked, "Uncle, let's talk about this courtyard house. I won't bargain. Just 1,800 yuan, how about it?"

This yard is pretty good, but if it costs 1,800 yuan, Mr. Zhang is certainly not happy about it.

The reason why he said so much just now, and the fact that it was almost the Lantern Festival and he still hadn't sold it, was because they hadn't agreed on the price.

Otherwise, if it was cheaper, it would have been sold long ago.

PS: I wish you all a happy Winter Solstice!
