Tech Hammer

Lu Dongyi really felt the change in Ning Wei.

He thought that learning about Jiang Chenlu's past from Teacher Liu would give Ning Weisheng more thoughts, but he seemed to be wrong.

His younger brother seemed to have turned into an emotionless robot.

Ning Wei just became more rigorous and didn't even ask anything about Jiang Chenlu. He was completely focused on constructing his basic mathematical theory of big data.

For three whole days, when Lu Dongyi arrived at the office every morning, Ning Wei was already there.

When he came in and greeted Ning Wei, his junior brother didn't even respond. It was often when he was drinking water or getting up to go to the toilet that he would suddenly notice that he was here and then take the initiative to say hello.

However, without waiting for his response, Ning Wei went to do his own thing, then sat back down and started working.

As a result, several fellow doctors and senior fellow students did not dare to disturb him when they came to fetch food and water as agreed.

When Ning Wei went crazy before, everyone could only feel that this guy was deliberately causing trouble, but now that Ning Wei was alarmed and he glared at him, even Zhou Yanping felt a little scared.

Zhou Yanping also asked Lu Dongyi privately: "Professor Lu, what's wrong with this boy Ning Wei? Why does he feel like a different person? When he glares at people, it almost feels like Director Tian getting angry?"

Lu Dongyi didn't know how to answer, and finally condensed it into one sentence: "Anyway, just don't provoke my junior brother recently."

…

In fact, Lu Dongyi was quite worried about Ning Wei in this state, but he seemed to have nothing to do.

He reported Jiang Chenlu's matter to Tian Yanzhen, but there was nothing further for the time being. Ning Wei didn't respond at all, and it was even worse for him to ask, so the matter could only be delayed there. Because Lu Dongyi always felt that it was inconvenient for him to act more urgently than Ning Wei.

Of course, he also believed that Director Tian must have his own arrangements. It’s not because Jiang Chenlu, a female student, has a pitiable background, but because Lu Dongyi knows how much Director Tian values ​​​​Ning Wei. For a female student who shows such affection for Ning Wei, Director Tian will most likely not let her continue. After living like this, I have to find a way to help her.

Well, the emperors were not in a hurry, and it was useless for him to be anxious, so he could only wait quietly to see the arrangements in the courtyard.

…

But in fact, from Ning Wei's point of view, he felt that he had not changed much. It was just a very unique sense of mission that made him easily fall into a state of concentration.

To say that he fell in love with Jiang Chenshuang at first sight, in fact, Ning Wei thought about it carefully, but it didn't seem to have reached that point.

At most, it can only be said to be a feeling of unhappiness after a newly formed habit is broken and a small resentment when curiosity is not satisfied. In fact, it has little to do with the so-called love.

But after learning about Jiang Chenshuang's situation from Teacher Liu, he could really feel a string in his brain being touched, which made him naturally look further ahead instead of focusing on the small things around him.

At the same time, his ideas are also changing subtly.

On the night when he met Mr. Liu from the music classroom, he searched a lot on the Internet after returning home, including the country's poverty alleviation policy, the appearance of remote areas, and saw the voices and smiles of left-behind children in many videos. He also read a lot of posts, which also inspired him to want to do more.

Then he felt even more pity for Jiang Chenshuang, but he had no intention of interfering with how to arrange this girl.

Because when Ning Wei calmed down, he thought about many things clearly.

For example, compared with his shallow social experience, how can a self-reliant girl like Jiang Chenshuang let down her guard and be able to accept some help from the outside world so that her life can be better? Those teachers who face students every day They definitely have more ideas than him.

What he has to do is to maximize his value in what he is best at.

To put it bluntly, as long as the results of his research are good enough, the girls he has clearly expressed his affection for will definitely be able to live better and better, not even better, but better!

Because the big guys who have their eyes on him will definitely rack their brains to think of ways to change the girl's life.

On the contrary, if he behaves like a talent, then who would really care about how an ordinary female student is doing in school except him? Probably, at most, it’s just a bit of a touch, and then life goes on. You must know that Yanbei University has 15,000 undergraduates alone. Everyone has to worry about it. Which big boss can handle it?

This is Ning Wei's idea, so pragmatic that it even makes people feel indifferent.

This is probably why Lu Dongyi feels that Ning Wei has become emotionless. After all, people's thoughts can never be connected.

…

"Tp{N, Z, R, S, L, B, H, P}..."

Ning Wei had just sketched out this bunch of symbols on a new piece of draft paper when his cell phone on the side of his desk started to vibrate. Ning Wei picked up the phone with his left hand, ignoring Lu Dongyi next to him, and directly connected the phone. , the right hand continued its own calculations.

Since coming to Peking University School of Mathematics, few people have called him during working hours, so when he does call, it is usually about something real.

The call came from the office of Director Lu of Jiangda Laboratory. Ning Wei was a little surprised. Basically, Liu Cong would communicate with him once or twice about the progress of EDA in the laboratory every day, so there was nothing special, and usually Lu Changbin wouldn't either. Find him.

"Hello, Director Lu, hello."

"Ning Wei, I have good news for you. Huawei's first-generation engineering machine equipped with a turbulence algorithm chip has passed the test and is now in the process of connecting with the foundry to meet technical standards. It will probably go into mass production next month. "

"Oh, that's good. Huawei is very efficient!" Ning Wei sighed.

"That's right, do you know how many people work overtime every day for this project?" Lu Changbin said.

Ning Wei didn't agree, but just sighed in his heart, there are many people who are fighting for every second like him, which is actually good.

Lu Changbin continued: "Let me tell you something else. When the Huawei engineering machine was finished, President Yan Ming came to the laboratory again and talked to me about something. Huawei has been promoting the registration of patents in various countries recently, but recently Huawei has also received some news. Some peers have begun testing their similar products. It is highly suspected that your turbulence algorithm has been used without authorization. What Mr. Yan means is that I hope you will sign a full authorization later. To Huawei, if there is a need to pursue infringement issues in the future, their legal affairs will be involved in the lawsuit."

Ning Wei did not answer the question directly, but asked instead: "Director Lu, I also learned about Huawei on the Internet, but there seems to be a lot of controversy on the Internet. What do you think of Huawei from your perspective? For example, how do they pay taxes? Is it legal?"

Lu Changbin probably didn't expect that Ning Wei would suddenly ask such a question. He hesitated for a moment and replied: "If we only talk about taxation, the one I admire most is probably Huawei. You may not know that throughout the country, except for some large state-owned enterprises, Compared with central enterprises, when it comes to active tax payment, if Huawei claims that it is second, no one has the nerve to say that it is first. Let’s put it this way, do you think Huawei’s size cannot afford to hire those who have received tax refunds? A senior financial person who knows just about every company’s legitimate tax avoidance methods?”

"Of course!" Ning Wei replied.

Lu Changbin continued: "But Huawei's President Ren does not allow this operation, which means that Huawei has to pay at least more than 5 billion in taxes every year, but in fact these taxes can be deducted through R\u0026D investment and other methods. Including paying When grading employees' wages and paying year-end bonuses, they never calculate how to avoid taxes and maximize benefits. Do you think this pattern is formal?"

After listening to Lu Changbin's introduction, Ning Wei replied: "Understood, Director Lu, please go back and tell Mr. Yan for me. The turbulence algorithm authorizes them to do it according to their own circumstances. I don't care. In addition, please help Let me tell you, with the dignity of a mathematician, I guarantee that within at least two years, no other company will dare to produce similar products without their authorization. It’s just that I have been busy recently and have no time to pay attention to them. What is it specifically? They will know this situation at the STOC conference in September."

Lu Changbin said in surprise: "STOC conference? Did they invite you?"

Ning Wei replied: "Not yet, but I have made something recently. If the organizer of the conference is discerning enough, he will definitely invite me to go. Of course, it's okay even if I don't receive an invitation. Anyway, September at the latest , I can always find opportunities to show you some results.”

Lu Changbin didn't know how to evaluate Ning Wei's confidence, but after all, Ning Wei was invited to the SODA conference, so it seemed understandable to be more confident.

"Okay, I will convey Mr. Yan's message to you, but can you tell me what you have done? Does it have anything to do with others not daring to infringe on your turbulence algorithm?" Lu Changbin couldn't help but ask.

Ning Wei replied: "I was just about to tell you this. It has nothing to do with the turbulence algorithm, but it has something to do with Brother Yu. I have recently made some breakthrough results in mathematics. According to my theory, At least it can increase the speed of lossless network migration of YB-level big data by about a thousand times. I have calculated this several times. I plan to submit a paper to STOC based on this theoretical result."

"But it's just mathematical theory at the moment, so I want Brother Yu to choose this topic for his graduation thesis, and use my mathematical theoretical framework to design a specific algorithm program. If I receive an invitation letter from the STOC conference, Please also grant Brother Yu a leave. I will discuss this proposition with him and try to build the technology in the laboratory in half a year. After completing the doctoral thesis, I will ask him to come to Yanjing to help me. What do you think? "

Lu Changbin was speechless for a long time. What kind of magical speed is this?

How long has it been since Ning Wei went to the School of Mathematics at Yanbei University to mathematically solve the problem of large-scale data migration? If Yu Xingwei can really complete this project, let alone graduate with a doctorate, he will have no problem becoming a professor at any top university in China, and Yanbei University is no exception.

After hesitating for a long time, Lu Changbin finally confirmed: "Ning Wei, are you serious?"

Ning Wei immediately replied: "Don't worry, Director Lu, I have some things to add and improve here, so I won't tell Brother Yu for now. Please tell him for me later."

"Okay, okay, I won't disturb you anymore, hang up."

After hanging up the phone, Ning Wei threw the phone aside, and then found Senior Brother Lu looking at him with surprise.

"What's wrong? Senior Brother Lu?" Ning Wei touched his face, but it seemed like there was nothing.

If it weren't for the fact that the junior brother in front of him had already made so many achievements, Lu Dongyi would really suspect that this guy was making a fake call just now to show off.

"You just said on the phone that the thing you recently developed can solve the problem of large-scale data migration?" Lu Dongyi asked.

Ning Wei replied: "Yes, Senior Brother Lu, it's not like you don't know what I've been doing recently. Originally, I was preparing these things, and after Director Lu's project application was approved, I merged them together, but I didn't want to save some money. If you don’t have time, just separate these phased results first, write a paper first, and help my senior brother Yu gain experience by the way."

"That's what I'm thinking about. When Brother Yu comes to the capital, I want him to form a team and follow me. I'm mainly responsible for doing theory, and he's responsible for helping me verify these theories and make applications. Brother Yu When we come to form a team, Senior Brother Lu should be more helpful, after all, we are not familiar with the place here."

After hearing this, Lu Dongyi asked: "The Brother Yu you are talking about is the one who helped us prepare food when I first went to your laboratory, and later went to attend the SODA conference with you, right?"

Ning Wei nodded and replied: "Yes, Senior Brother Lu has a really good memory."

After saying that, he lowered his head and continued busy with his own affairs, leaving Lu Dongyi alone in a mess.

Ning Wei wanted not to disturb this state, but the feeling of a cat scratching his heart made him unable to calm down. He couldn't help but ask: "Well, junior brother, why don't you tell senior brother about yourself?" That’s the idea, how did you do it?”

"Huh?" Ning Wei raised his head and glanced at Lu Dongyi.

Lu Dongyi said quickly: "It's the mathematical theory of data migration."

Ning Wei nodded and replied: "Okay, I just want to recalculate it, and I can explain it to you by the way."

Lu Dongyi immediately came behind Ning Wei, leaned down and watched Ning Wei begin to explain.

"Actually, I have discussed this idea with you before. The simplest and most popular way to put it is to build a standardized digital map to label all fragmented storage data in the data center, and compare and transform these digitized feature codes. , to complete the theory of migration.”

"To be specific, you need to first understand that all big data carriers are a superstructure of typed primitives. It transcends the R domain. The data itself is a quantification with abstract attributes, and it can be generated through minimalist mathematical operations. , for example, 1/0=∞.”

"Definition 1. The mathematical model D of data is an abstract mapping of the real entity quantity Q on the measurement scale S. Its derived quantity is a real number D∈R, but the dimension it carries is S, that is, D fs: Q→ S…”
