Hammer of Technology

"If this matter is discussed, I don't need to stay in the laboratory. I will come back to live with you for a while, and make some preparations for the postgraduate entrance examination. After graduation, I may go to the capital. Now I will do some research at the School of Mathematics of Peking University, and then I will wait until December. After the postgraduate entrance examination, he formally entered Peking University School of Mathematics to study.”

"That's no problem! In the past two days, I've been rummaging through various recruitment websites. It's really difficult to find a job for a graduate of mathematics. I'm not reconciled to being a code farmer. A better position can be achieved. Not even the starting standard." Liu Cong said excitedly.

"Fuck! Liu Cong, you are so happy now! You don't need to go to the bank to check the gate! Damn, I don't know what the two of my family think, I feel that in their eyes, this world is not a serious job except for civil servants! Very Let me go back to take the public examination! Otherwise, I will mess with Ning Wei!"

Xu Ruixuan said with envy and hatred.

"Don't make trouble, Xu Mo of your family was fooled by you to apply for a master's degree in management at the University of Technology. You came here to mess with Ning. I think Xu Mo will cut you to pieces with that knife!" Liu Cong said contemptuously at Xu Ruixuan .

"No, isn't your focus a bit off? Didn't you feel that this guy was pretending just now? He said he was going back to the dormitory to prepare for the postgraduate entrance examination? You are ready! You go to the postgraduate entrance examination, and you let others follow you next year What do the children who take the postgraduate entrance examination together think?"

Luo Xiang said indignantly that his focus always had a strange taste.

"That's right... Ning Wei, you still have to take the mao's graduate school! Be a human being!" Xu Ruixuan immediately reacted and chimed in.

However, without waiting for Ning Wei to refute, Liu Cong said with righteous indignation: "What are you two talking about? We would rather go to the postgraduate entrance examination to set a benchmark for everyone to take the postgraduate entrance examination in the future, and to create an alternative scenery for the postgraduate entrance examination for the god of learning. Later generations worshiped and transcended! An event of profound significance to the history of China's postgraduate entrance examination, how did it turn sour in your mouth?"

125 A mathematician's farewell (seeking monthly ticket)

At noon, Liu Cong grandly invited the brothers in the dormitory to have a meal, resisted the urge to drink, changed into a suit specially bought for the interview, combed his hair to look like an adult, and then rushed to the I made an appointment with Dean Kong and went to the teaching and research room on the first floor.

In the large conference room next door, the head of Huawei’s human resources department is introducing Huawei’s corporate culture and periodic needs to the master’s and doctoral students who signed up for this lecture at Jiangda University. In the teaching and research room separated by a wall, the Confucius Institute After Chang Zai introduced Ning Wei and Liu Cong to Yan Ming, he left first, leaving space for the three of them to talk about things.

It was actually two people, Liu Cong knew very well that he came with a pair of ears.If it wasn't for Ning Wei, he wouldn't have had the chance to sit here at all.

When Dean Kong left, Yan Ming took the lead to open the conversation: "Ningwei, hello. I have heard a lot about your deeds these days, especially congratulations on your turbulence algorithm official public test has achieved great success. Others I don’t know about the news, but Huawei has made a complete technical report on the turbulence algorithm, and the effect can be described as perfect. Especially in the three waves of DDOS attacks in the early morning of the 16th, although the intensity was not large, 90.00% of the malicious attacks were It was rejected in advance by the turbulence algorithm. To be honest, my colleagues in the technical department deeply admire this."

"Thank you, Mr. Yan. In fact, I have always admired Huawei deeply. But I think we really don't need to flatter each other. Why don't you just ask, is your company interested in our turbulence algorithm?" Ning Wei went straight to the point.

This crisp style of conversation...

Well, probably because I have been in the mall for a long time, it is becoming more and more difficult to come across this straightforward style of conversation, which even made Yan Ming feel like he was back on campus, so he simply nodded slightly and replied: "That's right. , both our network equipment department and cloud service department are very interested in turbulence algorithms."

After the words fell, Ning Wei said: "Okay, I have created a plan specifically for the cooperation of the turbulence algorithm. Why don't you introduce it to Mr. Yan first?"

"Okay!" Yan Ming said simply.

Ning Wei sorted out his thoughts, and then said: "I think about the turbulence algorithm. First of all, it can be deployed on the server as software, but in fact, for a large network equipment supplier like Huawei, we can also use the turbulence algorithm. The functions of the EDA software are integrated into routers and switches. At the same time, I happen to have an EDA software project in hand, and I have already formed a document for the current specific situation of this EDA software project, and they are all here."

"My idea is that if the two parties want to cooperate, we can carry out in-depth cooperation around this EDA project. First of all, I will authorize the turbulence algorithm to this minimalist EDA, and at the same time write multiple algorithms including the turbulence algorithm into this This software. Although this software is only a semi-finished product now, it can be used by your company within a period of time. At that time, you can use this EDA software to design your own turbulence algorithm function according to your own equipment conditions. chip, and embed it into your network equipment to protect the customer's network security from the hardware layer. For your cloud server, you can also deploy the software part separately."

"You can even design chips with similar functions for your other products. For example, in future 5G application scenarios, there may be more devices that need to reject malicious crawlers or DDOS attacks. Of course, the first thing you need to pay is to establish a related technology The department assisted us to improve this EDA software. Of course, in the future, this EDA software will be licensed to the outside world, and Huawei will also earn the part of the profits you paid. If you can agree with my packaging plan, we can continue to work on it. How to carry out cooperation, as well as authorization fees, profit distribution plans, etc.

After listening to Ning Wei's words, Yan Ming was a little confused. He looked at Ning Wei and asked, "You guys even made EDA software?"

Ning Wei nodded, and replied: "Yes, and I applied for this project, and I am also responsible for it. But halfway through this project, I realized that it is really troublesome to complete this project with a laboratory. Mainly It is the cooperation with chip manufacturers in the later stage, some data in the laboratory is difficult to obtain, and if we want to test in the future, such as using our own EDA to design chips, we will also encounter difficulties in tape-out. "

"But if we both cooperate, the situation will be different. What is difficult for us is not difficult for Huawei. By the way, our EDA currently only supports chips with a maximum of 14NM process. This U disk has For the complete information of our EDA software project, you can ask your company's technical department to study it before deciding whether to cooperate."

After finishing speaking, Ning Wei handed over the USB flash drive he had already prepared.

Yan Ming took the USB flash drive from Ning Wei, pondered for a moment and said: "You are right, if it is this kind of cooperation, I really can't promise you today. But one thing, the plan you mentioned is up to me." Personally, I am still very interested. How about this, three days at the latest, I will give you news after three days, and may even take our engineering and technical personnel to visit your laboratory directly, is it convenient for you?"

"Of course it's fine!"

Ning Wei smiled and replied: "Since it is cooperation, of course we should treat each other with sincerity. You are welcome to bring people to visit our laboratory at any time. At that time, I will personally demonstrate and answer questions for you and Huawei's technicians who came to the site. "

……

London, England.

Handel, the editor-in-chief of the journal Nature, who has long been friends with Ning Wei, is on the phone with his friend Smith who is far away in the United States.

After two minutes of discussion about British-American relations and recent climate change issues, Smith finally got to the point: "You know? Handel, when I saw the email lying in the mailbox, and clicked on the link to see that After writing a paper, I found out that I had studied it for more than 2 days before, and I even remember the mood when I directly gave it a pass."

"Oh? Ha, if you say that, I probably understand what happened. So did you review the manuscript for the "Annual Journal of Mathematics" or the "American Mathematical Society" for the first time?" Handel asked without surprise.

The opposite side replied casually: "The latter. The greatest tragedy of science is that there are always some people who know that their time has passed, but still delusional to continue their glory. So they once pushed the wheel of science forward, and when they are old But you have to pull back fiercely, do you think this kind of person is ridiculous?"

Handel said indifferently: "Of course, if you apply some people to some countries, your statement can also be established. Smith, as I said before, you are a natural philosopher, and you have an extremely keen mind. Insight, but to study mathematics, too condescending."

"Hehe... Well, Handel, you may not be very happy with what I'm going to say next. If you really want to replace 'some people' with a certain country, are you mocking your motherland?" Smith said nothing Hesitantly retorted.

"Actually, in my opinion, the great revival of our British Empire has already been prepared. The only problem now is that we have an extra No. [-] Downing Street and the people who work hard in it every day. But you are different, You not only have one more White House, but also fifty more state capitals." Handel responded gracefully.

"Haha, well! You win, Handel, my old friend. Believe me, that paper is fine, and it is a waste of time to keep getting multiple people to review it. I have already talked to more than one peer who reviewed this paper. After discussing it in depth, everyone admires some of the mathematical ideas put forward. Of course, except for a senior who still fantasizes that he is still a guiding light on the road of mathematics. Especially now, publish that paper as soon as possible, maybe you can borrow it Seeing that kid’s limelight at the SODA conference, he’s getting a lot of citations.” Smith responded with a laugh.

"Thank you, Smith, as you know, I have never liked Americans very much, but you are an exception. I appreciate your magnanimity and look forward to our continued cooperation in the future." Handel planned to end the call.

But what Smith said almost made his jaw drop.

"No, no, we probably don't have much chance of cooperation. I decided to follow your advice and turn to study philosophy. I even quit my job as a professor for this reason. Recently I am reading "The Brothers Karamazov". I was very touched by the content displayed. What is faith? What is free will? What is morality? I can feel a door opening to me, the meaning of our existence as individuals? Human beings as a whole can this produce A real common will?"

"I don't know whether mathematics can explain the world for thousands of years, but I believe philosophy can. There are too many things worth thinking about in the ocean of philosophy. Is there really something hidden in the dark that restricts our exploration of the world? Which is the real ship of Theseus? My God, just thinking about these questions makes my soul tremble. So I will say goodbye to mathematics for the rest of my life and devote the rest of my life to these things that are more worthy of my thinking. "

Hearing these explanations, Handel didn't know how to reply for a while. Although he often said that Smith was a born philosopher, it was really just a joke.

It would be fine if Smith was over 30, but he is only in his [-]s, and he is far from the age when he wants to give up mathematics and study philosophy. You must know that he was once recognized by the world's mathematics community as the most likely to win the Fields Award. Award for one of the young mathematicians.

After a long silence, Handel suddenly said: "My friend, to be honest, have you been hit by that little guy? And have doubts about your talent in mathematics? Or should I send that little guy in Huaxia an email Email, tell him that he was once a rising star in the mathematics world, Mr. Smith decided to give up mathematics because of your birth, and he should be very honored to hear this."

"Oh? Thank you so much, my friend. By the way, you can give him my email address, and help me bless him, so that he can go further on the road of mathematics in the future! And tell him, any field has The place where the light can’t reach, but we can’t lose hope because of this. If he encounters similar problems on the road of mathematics in the future, he can email me, maybe I can help him. Although I decided to switch to philosophy But I still have many friends and students who still have a voice in the field of mathematics." Smith said indifferently.

"You are really crazy!"

"I just got a new life."

"No, you are just too rich. Even if you quit your job as a professor, you can still satisfy your luxurious life! I have said a long time ago that you guys with talents can't be allowed to be so rich! This is not God's preference , but a curse!"

"Okay, stop complaining, Handel, although the world has one less mathematician Smith, there may be one more philosopher Smith in the future. This is more exciting, let's talk here today. No need to send me an email in the future Papers, of course, if you "Nature" starts accepting philosophical papers, I am still willing to make some modest contributions."

After speaking, Smith hung up the phone directly.

Holding the phone, Handel stood for a long time, all the sighs in his heart finally turned into a heavy sigh: "Hey..."

It seemed he would have to send Ning Wei an email. He could tell Smith was serious about what he was dragging him to convey, but perhaps it should be sent on the day his paper was published in Nature.

Maybe Nature sometimes acts no more noble than its peers, but occasionally he doesn't mind having his journal be a ray of light piercing the darkness.

For his friends, this can probably be regarded as a sense of mission.

Well, let him shine the light this Thursday.

……

Ning Wei, a mathematician who did not know the direction for the first paper in his life that was submitted to the top journal at this time, decided to bid farewell to mathematics that he had studied for more than 20 years and switch to the embrace of philosophy.

But probably there is a thread pulling everyone's footsteps in the dark, but he is indeed preparing for more time for himself.

In fact, he has received a lot of calls these days, most of whom hope to seek cooperation, including bigwigs in the domestic Internet field. The boss is indeed qualified to say this sentence.

But for the time being, he politely declined.

He has no plans to hold talks with other parties until the negotiations with Huawei are finalized.

Having experienced several rounds of money temptations, he has become much more resistant to money temptations.

1000 million and [-] billion, no matter what the currency unit is, when there is no clear purpose, in Ning Wei's opinion, they are actually the same.

Anyway, he doesn't have to worry about food now.

Although he really doesn't have much money now, he has come into contact with executives of major companies whose worth may have exceeded [-] million. He has seen some people talking around them just to arouse a trace of curiosity from these executives, and he personally accepts them. But the business cards they handed over with smiles and enthusiasm...

Then I discovered that these rich people are actually not interesting.

As long as he doesn't care about these people's money, they will naturally become younger brothers.

Ning Wei feels that he can understand the Russian mathematician who proved the Poincaré conjecture, but did not accept the prize at all, and dismissed the $100 million prize...

Although he can't do this yet, he can vaguely feel the pattern.

It doesn't matter whether it's money or not, the most important thing is that the master is happy.

So cooperation, not seeking the most profitable, but seeking the right.

126 theoretical billionaires

Yan Ming kept the promise, and on the third day of the agreement, he brought twenty people to Jiangda's software laboratory.

The laboratory has already made preparations. Everyone has been notified, sticks to their posts, and is ready to give explanations to these Huawei technicians who come to check the code. Ning Wei also called Liu Cong early this day. come over.

The first time was a familiarity, and the second time, if both parties wanted to talk in depth, Ning Wei was going to officially recommend Liu Cong to Yan Ming.

……

The communication did not take the form of focusing on making a report.Because there is no need to explain in detail the functions of this EDA software and the goals that Ningwei hopes this software can achieve.

Three days is enough time for Huawei to thoroughly study the extremely detailed PPT he made, and then hold several meetings to decide whether to cooperate and determine the principles of cooperation.

So Ning Wei acted very frankly and asked Professor Xu to show the semi-finished EDA software for Huawei visitors, and then directly took out the source code for the visiting Huawei engineers to review.

A laboratory member is in charge of two Huawei engineers, sitting on the side, ready to answer questions at any time.

In five months, there were more than a dozen people in the project team, nearly a million lines of code and tens of thousands of matching documents, which were freely read.

Under such circumstances, the laboratory should be very noisy. After all, there are nearly 40 people crowded in the laboratories on both sides, and each group can ask and answer casually, which can make the laboratory full of "buzzing".

But the reality is that the laboratory is quiet most of the time, and even the sound of mouse clicks can be clearly heard.

Occasionally, there would be a question or two, but more often than not, no one would say anything.

If you want to rank the least favorite things of programmers, consulting the code of peers is definitely on the list.

It's so beautiful, but I can't understand it when I look at it, it's a mess, and it's annoying to read it!

But this time it’s obviously a different feeling. With a glance at the function name and class name, you can probably know the function to be realized by this program; the comments are more accurate, easy to understand, concise, and clear at a glance, especially the functional code modules.

Many functions that can already be understood through standard function naming still have concise and detailed comments. However, this is not the end. Each major function is supplemented by detailed documentation. What are the input parameters, what are the uses of these input parameters, the inheritance relationship and inclusion relationship are all recorded in detail.

What I saw gave many Huawei engineers an illusion. Where is this a software laboratory?Where are these professors simply working on a software project?I'm afraid this is not a courseware for training students, right?Really, with such code, it is not against the law to write it directly into the textbook.

During the break, a group of people began to complain.

"Is Jiang University's code quality so high?"

"It's better not to rush the deadline! If the code quality provided by the partner is all this, our workload can be reduced by at least five times."

"That's not necessarily the case. I heard that the project team was only established in November last year. It's only been five months since it was fully worked out. It's not too late, okay?"

"Hey, Cheng Guowen, I remember that you were a graduate of Jiang University before. By the way, you Jiang University has such a rigorous coding style, why haven't I seen you learn it?"

"You know what a fart! Don't you know that Jiang University is the most low-key school in the world? I have to keep a low profile too! Otherwise, wouldn't it be out of place with you? This is also an inheritance of Jiang University's style! Understand?"

"roll!"

……

The exchange plan lasted for three days, but after the first day of exchange ended, Yan Ming, who had received a preliminary report, had already decided to promote this cooperation.

In fact, it has nothing to do with the unexpected high quality of the code. The conclusion of the internal meeting is that as long as this EDA software can be used immediately and design a turbulence algorithm chip that can be used in network equipment, as Ning Wei said in the introduction, it must be promoted. This cooperation.

Think about it, once a network device that can effectively isolate malicious crawlers from crawling various sensitive data at the hardware level and can actively defend against DDOS attacks is officially launched, how huge will this market be?

It only needs to be one step ahead of its friends and businessmen to establish in the public's mind that Huawei's network products are more secure, which is inestimable for the improvement of brand value.

The high quality of the code can also be considered a pleasant surprise.

The first formal exchange of views took place in Lu Changbin's office.

A total of four people participated, Yan Ming, Lu Changbin, Ning Wei and Liu Cong.

Except for one paddling, it just represents the interests of the three parties.

"Let's get straight to the point. Huawei is very interested in this cooperation, so I want to hear the cooperation model proposed by Mr. Ning Wei first."

"Director He, President Yan, this is what I think about it. First of all, Huawei invested in buying the right to use EDA software from me and the laboratory. After confirming the ownership of the right to use the minimalist EDA software, the laboratory and Huawei can form a strategic partnership. , the two parties will continue to conduct in-depth research and development on this topic, divide labor and cooperate, and continue to enrich various software functions planned by the minimalist EDA. You can discuss the specific cooperation method with Mr. Yan, and I will not interfere."

"Second, when it comes to the turbulent flow algorithm, I will authorize this algorithm to the minimalist EDA. I think the specific patent licensing fee can be calculated according to the usage. In the future, every time Huawei sells a device equipped with a turbulent flow algorithm chip, it will Pay me a patent fee, I have considered it carefully, and I will charge a patent fee of [-] yuan per unit, which will be settled on a quarterly basis.”

"Third, after the minimalist EDA software is finished and officially launched to the market in the future, I will account for 20.00% of the income. My request is probably like this. In addition, after putting aside the things here, I may not have much I have no energy to take care of these matters, so I entrust Liu Cong with full authority to handle these matters on my behalf. This is probably what I think. What do you think?"

Yan Ming and Lu Changbin looked at each other.

After pondering for a while, Yan Ming said, "I personally think the problem is not big, but some details still need to be sorted out. Let's not talk about the cooperation model between us and the laboratory. It is reasonable for Huawei to only get the right to use EDA, but if we Is it unreasonable to participate in the development of EDA software, but only have the right to use it? Moreover, the turbulence algorithm is authorized to Simplified EDA, not directly to Huawei. This may cause legal problems in the future cooperation process question."

Lu Changbin smiled, and then said: "If Yan is always worried about any conflicts in the future, I think we can talk about it. I probably understand that Yan is always worried about the promotion of minimalist EDA in the future. There may be some preferential policies, such as involving When using the turbulence algorithm, we will give certain discounts. How about I help Ningwei to be the master, and the contract directly states that the patent licensing fees for other friends to use chips with turbulence algorithm in the future shall not be lower than the licensing fees for Huawei? "

"What about the use of the turbulence algorithm software version? For example, if Huawei wants to upgrade the turbulence algorithm protection for Huawei Cloud customers for free, can it be used directly?" Yan Ming asked again.

"No, no, these are two different things."
