Hammer of Technology

"Okay! Then give me your email, and I'll send it to you."

"Okay, wait for the WeChat chat."

……

After hanging up the phone, Zhang Yancheng didn't feel sleepy at all.

Although Ning Wei's speed was so fast that he couldn't believe it, but thinking that Ning Wei didn't seem to have any reason to tease himself, he decided to find out what was going on, so he immediately approved a piece of clothing and started to get out of bed.

The roommates in the room were still fighting at night with the lights on. It was not too strange to see Zhang Yancheng answering the phone and not falling asleep. Everyone had the same experience before. They just glanced at it and asked, "What did the boss give again?" Have you arranged a mission?"

"No, the foreign aid who told you said that there is a result."

"Huh? Sharpshooters don't have this speed, do they?"

"Who knows, let's take a look first." Zhang Yancheng replied with his head down. He had already sent his email address to Ning Wei as quickly as possible.

"No, what I mean is, Lao Zhang, if someone solves the problem in such a long time, have you ever thought that this explains a problem." The roommate put down the book in his hand and said something.

Zhang Yancheng raised his head, looked at his roommate and asked, "What's the problem?"

"You may not be suitable for the direction of material research! Hahaha..." The roommate said unceremoniously.

"I..." Zhang Yancheng wanted to refute, but suddenly found that he couldn't find a reason.

In fact, it makes sense. After all, Ning Wei is a PhD student in mathematics. How can he solve the problem that has troubled them for a long time so quickly?Is there any law of the king?

"It's not certain. People didn't say they were [-]% sure."

Zhang Yancheng said casually, then turned on the computer, and just logged into the mailbox, a message was sent on WeChat, with an "ok" expression.

He didn't make him wait long, refreshed, and a new unread email was lying in the mailbox.

Click on the email to download the attachment, open it with the software, and the moment he saw the model results and report, Zhang Yancheng was stunned.

My head is full of all kinds of ridiculous ideas...

For example, I just wanted to build an anti-aircraft gun and I was satisfied, but you threw me a Dongfeng express suit?

After reacting, Zhang Yancheng immediately replied on WeChat: "Are you kidding me?"

178 A God-like Top Talent

Soon, the opposite person replied with a "?" on WeChat, which was concise and thought-provoking.

But seeing the question mark, Zhang Yancheng felt that he had lost.

That's right, no matter which direction he thinks about, he can't find a reason why Ning Wei chose to stay up late at night to call and tease him.

So he quickly replied: "90.00% sure?"

"Well, only 90.00%!"

"Then let's do it. I'll go to the research institute to invite you tomorrow?"

Zhang Yancheng may not have realized that he unconsciously used the honorific title when chatting with Ning Wei. He probably only used this title to his boss in school.

"What's so troublesome? What time do you go to the laboratory? I'll go straight to you when I get there."

"We usually arrive at eight o'clock, but we still need some preparation time. You can come at nine o'clock."

"OK!"

Taking back the phone, Zhang Yanchang sighed.

"What's wrong?" the roommate asked.

"Mathematics is omnipotent!" Zhang Yancheng said with emotion.

"are you crazy!"

……

"Isn't it? Brother Zhang? Do you really believe that doctor of mathematics? He left at 11 o'clock yesterday afternoon and told you that the problem was solved at 30:[-] in the evening. He just made you a mathematical model and you really believe it?" The only person in the laboratory Xiao Pan, a graduate student at the university, was complaining.

The main thing is that it is too fast, and it feels like a joke.

"That's right, Lao Zhang, I also don't think it's very reliable. Is that Ning Wei joking with us? He was like a curious baby in the laboratory yesterday. You understand, I think he understands something , but I don’t understand that well! The performance of some instruments has to be confirmed with us repeatedly, but the problem was solved one day after returning home, and the model sent was still a joke. Is this a joke?” Ning Wei was deeply impressed. Old Xu was also questioning.

"Brother Zhang, I also think we still need to be careful. Is Ning Wei reliable?"

Zhang Yancheng smiled, but his face looked bitter, and this smile seemed a little weird: "Oh, it seems that everyone is very energetic today, so, when Hui Ningwei comes, I will let him go back directly. Today you each come up with a plan, and tomorrow we will arrange according to everyone’s age, and change the plan every day. If you can’t finish it, you can report to the boss that we can’t do this project, how about it?”

As soon as this sentence was said, no one said anything in an instant.

Well, in fact, Ning Wei, who was walking on the road, was also quickly verifying whether March's calculation was correct in his brain.

After completing the amazing move in March yesterday, Ning Wei tried again to replace a project of the same type of material, and handed it over to March for calculation.The difference is that this time he used a published paper to blur the data in order to ask March to review the entire experimental process.

However, one night passed, and when Ningwei got up in the morning, he rushed to check it excitedly, but found that March hadn't given the result yet.After checking the overall calculation records in the background, March has already begun to verify the No.17 set of plans that he drew up by himself.

The previous sixteen sets of plans were all abandoned due to various reasons that could not achieve the ideal model results. Judging from the calculation process of the No.17 set of plans, it is far from the smooth completion process in Ning Wei's mind.

It was like pouring cold water on Ning Wei's head.He originally thought that San Yue's ability in terms of optimal selection was extraordinary, but judging from the efficiency shown by San Yue this time, he doubted that San Yue could quickly complete Lao Zhang's project, or there really was an extremely rare experiment It may be a coincidence in the room, or there may be some data errors. Fortunately, Ningwei is sensitive to the data. After checking it again, he can probably judge that the possibility of data errors is very small.

Then it was a laboratory coincidence.

However, blaming everything on the coincidence of the experimental process in March, which combines scientific rigor and unreliable luck, makes Ningwei feel weird, because he can't even tell whether this is a project. The luck of the group is still their own or March luck.

I regretted notifying Zhang Yancheng too early yesterday, otherwise he would have a few days to carefully analyze the data and do calculations, and then send it to March for re-verification.However, there is not much worry, after all, the success rate is still extremely high.

When approaching the Materials Science Experimental Building, Ning Wei sent a message to Zhang Yancheng, and when he arrived at the gate of the building, the senior was already waiting for him at the gate.

"Mr. Ning, here you are. Everyone is waiting for you. To tell you the truth, everyone in our project team expects you to create a miracle." As soon as we met, Zhang Yancheng gave Ning Wei a gift without hesitation. Top hat.

"Well, let's talk about it when we're done." Ning Wei said noncommittally.

After all, the current politeness is only temporary. If the experiment is not successful, Ning Wei thinks that Senior Brother Zhang probably won't show such a good temper.

In fact, walking into the laboratory, Ning Wei could feel that what Brother Zhang just said was bullshit.

Although no one showed their faces, he could feel the atmosphere. If everyone had expectations, the atmosphere should be joyful, not like being in a high-pressure gas tank.

"Okay, let's start directly. Brother Pan is in charge of the first stage, right? The previous steps are the same, but in the stage of mixing the fibers, the second sample and the third sample are fused at the same time, and then the electrolyte is gated Technology for electron injection and hole injection. Annealing does not need to use 350°C annealing process, just perform 500°C annealing process, "

Ning Wei didn't waste any time and spoke directly.

It took a full four hours to demonstrate the laboratory last time. If the experiment is officially started, it will take longer.For example, it takes nearly four hours to complete the entire annealing process.If you want to get results today, you really have to hurry up.

"This..." Xiao Pan glanced at Zhang Yancheng, but still asked, "Dr. Ning, is there any theory or mathematical basis for this?"

Ning Wei said bluntly: "Yes, but it is more troublesome to explain. Instead of wasting time, you should do it first. I will explain it to you slowly later."

"Xiao Pan, why don't you come over to me?" Zhang Yancheng said.

"No, no, here we come."

"Well, be careful, don't cause problems..." Ning Wei warned.

Don't be lucky if something goes wrong with a single human error, it won't be worth it.

"Use two more sets of samples, do both sets together, and record every step." Zhang Yancheng explained another sentence on the sidelines.

"Ok!"

……

Ning Wei couldn't get involved in the specific experimental process.But he still observed it very carefully, after all, these are rare experiences.

This time Zhang Yancheng did not go to work on his own, but stood next to Ning Wei and stared at it. This time, Xiao Pan was a little nervous. Fortunately, he has done the same thing many times. As for going wrong.

Two hours later, Xiaopan completed the previous steps, put the two sets of samples into the vacuum oven, and started the annealing operation.

"OK, there should be no problem. Then I'll go first. After the annealing is completed, follow your previous steps for processing and testing, and let me know when the results come out." Seeing that Xiaopan had completed all the operations, he controlled the temperature. After the device was adjusted to 500°C, Ning Wei spoke.

"Well... why don't you stay and wait, it's almost time for lunch, why don't you leave after eating?" Zhang Yancheng said enthusiastically.

"Not yet, to tell you the truth, our Director Tian is urging me to complete the top-notch youth project every day. I wasted a day and a half for your project. I have to make up for it quickly." Ning Wei replied with a smile .

After saying this, everyone in the entire project team fell silent and couldn't continue.

Some people don't see any intention of showing off, but such a low-key sentence makes people feel extremely depressed.

Looking at that green face that hadn't fully faded away in time, he opened his mouth to plan a top-notch youth project to drive thousands of people away. There is no good excuse for people to keep them for a while. The crushing of strength makes some people want to question it. Feel free to speak up.

He just graduated from college, so he should be at most 23 years old, right?Heh, a 23-year-old top-notch youth, if he races against time to complete the project, wouldn't he be able to apply for outstanding youth in the next year or the next?

"Then, you'd better get busy first, we can't make the boss anxious." Zhang Yancheng swallowed and said.

"Hmm... okay, remember to let me know when there is a result." After speaking, Ning Wei turned and left the laboratory.

After Ning Wei left, everyone's eyes fell on the vacuum electric oven, and the scene was completely stunned.

"What a goddamn top-notch young man... We don't know if we will have this opportunity in this life." Old Xu sighed, touched his head, and suddenly felt that his hair loss was not worth it.

"Okay, don't sigh. We don't understand other people's world. We will be thankful if we can get this project done first. Speaking of which, if this experiment is really successful and I finish writing the thesis later, I will be ashamed to put myself on it." It's gone." Zhang Yancheng said in a muffled voice.

Everyone in the project team was taken aback...

That's right, no one has thought about this problem just now. If this project is carried out according to the steps that Ning Wei pointed out, it is really successful. Whose credit is it?

After all, it is no longer as simple as giving a math report, but directly coming to teach them how to operate it. If the problem is not solved, it is possible that this project will be sealed. The credit is even greater, it's really hard to say.

"Well, even if it really succeeds, Dr. Ning shouldn't care about our small achievements, right?" Xiao Pan said hesitantly.

"Don't think too far, it's up to you to decide whether it's possible or not. Let's wait until the batch of samples comes out and tested." Old Xu said sullenly.

……

Ning Wei really didn't know that a reason he just made up casually made several members of the project team start to have a tendency to collective depression.

To be honest, as far as he is concerned, he doesn't care much about the titles of top-notch youth and outstanding youth. Anyway, he just said it casually. After all, he is only a Ph. Graduation thesis.

He had just walked downstairs to the laboratory when his cell phone rang, and after looking at it, it was a call from his old acquaintance, Mr. Yan from Huawei, and Ning Wei quickly connected the call.

"Hello, Mr. Yan, what's the matter?" Ning Wei asked.

"Mr. Ning, hello, I'm making this call to inform you that the company has sent you the income from the turbulence algorithm software version from April to August, and the specific turbulence algorithm chip authorization fee needs to be settled next month. The settlement can only be made after the revenue of the third fiscal quarter, Mr. Ning, remember to check it. In addition, the specific report has also been sent to your mailbox, if you have any questions, you can call me directly."

"Oh, how much is it?" Ning Wei asked.

"After deducting taxes, it is about 7.4 million yuan, and the tax payment is about 1.8 million yuan. You can check the specific tax payment situation in the personal income tax APP next month." The opposite side replied.

"Eh? There are so many?" Ning Wei was a little confused.

After all, according to the previous statement, Ning Wei felt that the biggest benefit of the turbulence algorithm should be in the authorization of the algorithm chip, and the specific software deployment took the path of low-cost promotion. He never thought that it would bring him even five months. More than [-] million in revenue.

"Ahem, this is mainly because the algorithm works very well. Several large cloud service providers at home and abroad have all obtained authorization in the early stage, and some large service providers are more interested in the preferential policies launched in the early stage. I bought ten years of usage rights at one time with several major airlines, you can check the report for the specific situation.”

"Okay, I'll trouble you, Mr. Yan." Ning Wei thanked.

"By the way, there is one more thing. I mentioned it to you last time. Recently, when we were negotiating with users in many countries such as Europe and the United States, we have found that there are imitation hardware and software devices with algorithm chips on the market. We The legal department has already started preparing to file a patent lawsuit, but I remember that Mr. Ning seemed to say that there is a way to respond to this kind of piracy last time, so..."

"I was so busy that I almost forgot about this, so I will send you a demonstration video later, so that you can demonstrate it to customers. If the turbulence algorithm software or chip that uses our core program has not been activated with a specific activation code, it will Some wonderful things happened. For example, the software stopped working. I don’t know how the other party’s hardware is laid out. If it is more serious, it can directly cause the entire system to stop working.” Ning Wei replied.

"Ah?! Well, Mr. Ning, didn't you say that the core code of the turbulent flow algorithm deliberately left a back door?" Yan Ming's voice became obviously tense.

This is a big joke, the standard way of killing [-] people and hurting [-] people.

"Yes! But Huawei's products don't have backdoors. My main business is to study mathematics, and doing algorithms is just for fun. So when writing the core program, I added a few special codes, which are indeed similar to backdoors. program, but before you burn the code into the chip, you need to activate it on our EDA software after the packaging is completed."

"After receiving the activation instruction, the code in the core code that hides the backdoor will automatically simplify itself according to the set function result, so there is absolutely no problem with the certified product. Without this step, or unauthorized modification of the code For products that have been modified and then directly burned, as long as the backdoors left in the original code are not deleted, there are really backdoors.”

------------

179 It's still too pure

Hearing Ning Wei's words, Yan Ming was completely dumbfounded. What could he say?This is so terrible.

According to his understanding, before burning the chip, the activation program needs to be run first, just to facilitate Ningwei to know how many devices he has sold through the background. After all, according to the agreement signed by Huawei and Ningwei, the patent authorization settlement is based on the number of units sold. .

It never occurred to me that this had a second meaning.

What makes Yan Ming sigh is that it is a good thing that Huawei never thought of omitting this step to achieve the goal of paying less patent fees, otherwise, it would be really fun.

God knows how many people in foreign countries are staring at their devices every day, hoping to find a backdoor program in the device to make use of the problem. If they are really caught, it will not be a matter of the licensing fee.

At the same time, Yan Ming's eyes lit up with Ning Wei's words, if this is really useful...

"Mr. Ning, how about this? Now that we have purchased several similar products from other companies, why don't you provide this method to our engineers for testing? It also includes our own products. And please cooperate with us, if after the test This method is effective, please do not publicize this technology for the time being." Yan Ming said immediately.

"It's okay to teach your engineers the method and test it, but why not publicize it now? Just announcing the technical principles should put you in an active position when competing for customers, right?" Ning Wei asked casually.
