Tech Hammer

Ning Wei first picked up the phone.

Sure enough, the phone with silent mode turned on was about to explode again.

There are more than twenty missed calls and even more messages on WeChat.

Senior Brother Lu, Dean Kong, Director Lu, Director Li, Senior Brother Yu from the laboratory, several professors, three brothers in the dormitory, and several classmates with whom we had good relationships on weekdays all called.

Except for the brothers in the dormitory, everyone else Ning Wei came back one by one, saying that they were fine and saying thank you.

It took half an hour just to call me back.

I chatted with Dean Kong for the longest time, and Ning Wei understood the big brother’s words. Next time I need academic exchanges, there are many professors in Jiang University. If you have nothing to do, don’t contact Senior Brother Lu, otherwise you will be led astray... …

Then I discussed some issues with Senior Brother Lu.

I told the others that I was safe.

Then I started looking at WeChat, and sure enough, there were class groups, dormitory groups, social dormitory groups, all the groups were blowing up.

The painting style in the dormitory group is still the familiar dance of demons.

" @I'd rather be sorry, my father wasn't there at the time, otherwise I would definitely punch him and let him know how powerful the iron fist in dormitory 302 is!"

" @Ning Wei, is something wrong? Just say something if anything happens!"

“ @Ningwei, no matter how fierce the online commotion is, you must remember that your father’s love for you will never change, and we will always support you!”

The girls in the dormitory group were also asking about his situation with concern.

As for the class group, they were even more angry. They just couldn't organize a group of people to come to Yancheng to keep Ji Ziheng here forever.

Ning Wei quickly showed up, and there were several messages in each group.

He probably got dizzy while doing the questions on his own, kept his phone silent, and didn't see anyone's messages. He actually had nothing to do, and he didn't even notice the storm on the Internet...

Seeing the reply from the real owner, the group suddenly became more active.

Ning Wei spent another ten minutes joking with everyone in the group, and then turned on the computer to surf the Internet.

On the Internet, Ning Wei began to understand the whole incident from a third perspective.

Yes, although the popularity of this matter is still increasing on the Internet, and he is even one of the parties involved, he has not been involved in it from beginning to end, and he has to get to know it again.

Fortunately, Weibo sensitively noticed this hot spot and directly created a topic, and related Weibo content and discussions were added to it.

This saved Ning Wei a lot of time. From Yanbei University’s official Weibo voice, to Jiang University’s support, from Director Tian’s speech, to the recording released by Senior Brother Lu, to many friend schools speaking up for him, and there are many lovely people The classmates, brothers and sisters spontaneously organized support on Weibo...

If you're not moved, that's fake. I feel warm in my heart from beginning to end.

He also saw a little girl who was probably still in junior high school. She announced in a high-profile manner that she would no longer be a fan of her idol on a related topic, and she would start studying hard from today...

Finally, he came across Ji Ziheng's latest video statement... Well, this one is a bit boring.

But no matter what, at this moment he felt that his decision to stay in the country was simply too wise.

If he were abroad and encountered such a bad thing, would there really be so many people spontaneously speaking for him?

Ning Wei also wanted to say something.

But suddenly he discovered that he didn’t have a Weibo account yet. Fortunately, it was very convenient to apply and then register with his real name.

After succeeding, he looked at the topic and didn't know what to say. Although he was grateful, his thoughts were stuck at this moment.

The brain of the top student in Kongyou was troubled because he couldn't think of the appropriate words for the occasion.

At this moment, the phone suddenly lit up and rang.

Ning Wei thought about the number from Beijing and picked it up.

"Hello, are you Ning Wei, a student from the School of Mathematics and Statistics of Jiangnan University?"

"Oh, I am, who are you?"

"Oh, hello Ning Wei, my surname is Pan, and I am a staff member of Sina Weibo. We saw in the background that you have just applied for Weibo. Do you need us to help you with an official real-name authentication? After authentication, This will show your officially certified identity on your Weibo, and also prevent someone from pretending to be your identity to confuse the public.”

"Trouble?"

"It's not troublesome. It will only take five minutes at most. I will guide you to submit some information."

"That's okay."

…

Ten minutes later, Ning Wei looked at the verified Weibo and finally thought of the words.

"I'm Ning Wei. I just saw the whole thing. Thank you for your trust and support. I want to say something, but I don't know what to say! So I wish you all a happy new year! I wish you all a happy and monotonous new year. Increasingly, troubles are high-level and infinite, good luck is continuous and divisible, and ideals are bound to reach their peak!"

Didn't try to explain anything.

Because Ning Wei found that it was not necessary at all. Everyone had already explained all the judgments based on logic and rationality for him. It would be superfluous to explain that he did not say those words.

Moreover, Ji Ziheng's latest statement had already discussed the cause and effect of the matter, so it would be meaningless for him to repeat it again.

That's it, pretty good!

After doing this, he closed Weibo, took a deep breath, and began to download the latest experimental data uploaded by the laboratory today. He continued to make various records and comparisons. When he was relaxed, he suddenly felt inspired and began to compile all the abnormal data. Categorize, and then stack according to a mathematical method that came to mind when I was inspired today.

Soon, Ning Wei seemed to find patterns in these complicated data.

Finally, he found outliers one by one in the countless complicated data and classified them again. Ning Wei found that all the abnormal data found met the characteristics of normal distribution under certain circumstances.

This time I finally got a clue.

Comparing the characteristics of the data, Ning Wei finally discovered that all the erroneous data also pointed to a problem in the regression part of the algorithm.

The turbulence algorithm needs to go through multiple layers of judgment when reading abnormal data streams, and pre-marks the initially screened suspected crawler or malicious connection signals, and then imports them into its own database for data comparison in the next stage.

For example, the most superficial determination of non-compliant browser headers or browser headers containing crawler information, as well as the determination of the number of visits to a certain type of IP within a certain period of time...

After processing hundreds of millions of normal connection requests, record the data characteristics generated during data convection, compare it with the abnormal data in the database, try to put it in, compare it again, issue a verification code, and compare it again. In this process, the last thing fed back to the algorithm is the abnormal signature of the data flow, and the signals that match the abnormal signature are marked instead of marking the specific IP.

The problem lies here. During a certain recursive process, a very small number of normal requests encountered exceptions during the process of comparing and automatically recording feature codes. This resulted in all data of the same type of features being misjudged by the system. .

At this time, the benefits of making the documentation sufficiently detailed are reflected.

I found the reason why the misjudgment rate in laboratory tests could not be reduced, modified the idea, and then just consulted the documents, and quickly found the parts that needed to be modified accurately.

The popularity of programming is definitely well-deserved.

It only took three hours for Ning Wei to update the program and send it back to the laboratory.

Although it was already late, he still called Yu Xingwei again.

"Hey, Brother Yu!"

"Mr. Xiao Ning, do you have any other instructions?"

The two of them had already talked on the phone just now, so there must be something wrong if they call again.

"I just updated the turbulence algorithm and sent it to the laboratory. You can deal with it tomorrow and do the second round of testing again."

"Um?"

Yu Xingwei was stunned for a moment, and then said sincerely: "Mr. Xiao Ning, I'm impressed by you. There are so many messy things today, but you are still in the mood to change the code."

"Well, there are indeed a lot of messy things. Didn't this get solved before I even reacted?"

It sounded so sincere and reasonable that it made Yu Xingwei envious and jealous.

"Mr. Xiao Ning, you have another trait that I admire."

"Um? Is there any?"

"Yes, you really know Versailles!"

Ning Wei: "..."

…

Lu Dongyi arrived in Jiangcheng last night, rested there for one night, and took the earliest high-speed train to Yancheng the next day.

So Ningwei had to rush to the train station early in the morning to pick someone up.

This time Ning Wei learned from experience and wrapped himself up very tightly.

The hat covers his forehead, the scarf covers most of his face, and he is paired with a bloated down jacket. It is really impossible for people who are not familiar with him to recognize him.

This outfit was indeed useful. In order not to miss the time, Ning Wei directly booked an online taxi. The driver was obviously very talkative. As soon as he got in the car, he started chatting with Ning Wei, and it was still Ning Wei.

"Brother, at your age, you are also a college student returning to Yancheng to celebrate the New Year, right?"

"yes!"

"Speaking of college students, you know Ning Wei from Jiang University, right?"

"Yeah, I know." Ning Wei, who was sitting in the back row, responded passively.

"He is the pride of our city now! Were you online yesterday? Let me tell you, it was so exciting! I ate that melon yesterday all night long! It was so delicious!"

Ning Wei didn't know what to reply, so he casually said "hmm", feeling a little guilty. After all, this elder brother had eaten melon all night yesterday, and he didn't know if he was in good spirits or not...

"Hey, don't feel pressured. After all, people like Ning Wei need talent. I'm not bragging. I was actually pretty good at studying back then, but I just played around in my senior year of high school. I really regretted watching those things yesterday. I turned around and beat my son hard. If that kid didn't go to school well, he still had a score of 70 in one subject in the final exam! So, you are also a college student, so you must cherish the opportunity!"

These words made Ning Wei feel guilty and couldn't help but ask: "Brother, you look quite young. How old is the child?"

"Haha, I'm already 36, so young! My son is nine years old this year and is in the third grade."

"Actually, there is no need to worry about academic performance in third grade..."

"Hey, you can't say that. Yesterday I was browsing Douyin and saw someone talking about Ning Wei's growth history. It is said that he was very naughty and didn't like to study when he was a child, and he was beaten out! This makes sense. In elementary school, Developing study habits is the most important stage, and you must develop good study habits in order to benefit them throughout your life.”

"this……"

Ning Wei was stunned when he heard these words.

What kind of god is this? He is so heartless. How much hatred does he have against a primary school student?

This method of squeezing traffic is also perfect.

He vaguely remembered that when he was a child, his grades never worried Lao Ning.

Being beaten was common in elementary school, but it was basically not because of study. After junior high school, Lao Ning rarely did anything.

"Actually, I don't think Ning Wei is as good as he is boasted on the Internet. He is actually quite ordinary. His grades in elementary school may be just like that. And I think it is difficult to develop good study habits from an early age just by playing, right?" Ning Wei worked hard to save a child's childhood.

"Hey, how can you speak like this? What do you mean, not so awesome? If something happens to him, so many universities will come forward to help him? Even the official Weibo of Yanbei University said that all foreigners want to talk to him. Take it away! Eight hundred thousand dollars a year!"

"Brother, I'm telling you, don't talk nonsense outside, be careful of getting into trouble! You don't know, I passed by the Cultural Square last night and saw a group of young people surrounding the hotel where the little star was staying. They were still shouting slogans at the door of the hotel to ask the agent to come out and confess. There were more than a dozen people surrounding the live broadcast. The police didn't even chase them away. TV reporters came, and the hotel owner probably It’s going crazy.”

"Also, those people also called on everyone in the short video not to go shopping in New Times Square, so that the bosses who invited Ji Ziheng to come would lose their money and so on. But the excitement was ruined. How else could I eat melon all night? ? Our small town has rarely been so lively since the heavy truck moved away."

"Is there such a thing?" Ning Wei was shocked when he heard the news.

"You don't watch short videos at night? There were a lot of short videos about this in Yancheng yesterday.

Last night, after he replied to Weibo, he went about his own business. He really didn't know that something like this would happen later.

I couldn't help but feel glad that he had wrapped himself up well enough when he went out today. If he was recognized recently...

Just as he was secretly rejoicing, his phone vibrated. He looked at the number and saw that it was Dean Kong's, so he hurriedly connected it.

"Ning Wei, a professor from our school's law school will contact you later. Please cooperate with him as he asks. Yesterday's matter is not over yet. The opinion of the law school is that the other party has met all the objective requirements for defamation. It constitutes the essential elements and has caused extremely bad social impact, but because this is a private prosecution case, you have to cooperate."

"ah?"

Ning Wei carefully glanced at the driver in front of him and whispered: "Dean Kong, is this unnecessary?"

"There's nothing we can do about it. Yesterday, our law school was attacked by a group of brother schools. If this matter just goes away quietly, where do you want the face of our school's law school to go? From now on, the dean , professor, you are going to attend a conference, and you are going to be laughed to death by your brother's school? But don't worry, I have asked for you. You only need to cooperate with our law school to provide a power of attorney, and you don't need to worry about anything else. .”

"Just leave it to them. Don't worry, our law school still has a great influence in Beihu, and it won't waste your time. Even if you don't get a real sentence in the end, at least it will be a reprieve and it can help some people improve their memory. . Think about it, this time you are lucky enough not to give those people a warning. If you were an ordinary person next time, wouldn't you be unjustly killed?"

"That's okay!" Ning Wei responded.

"Okay, remember to cooperate!"

The other person hung up the phone, and Ning Wei sighed in his heart.

What does it mean to live by one's own fault? If what Ji Ziheng said in the clarification video is true, the agent performed this sentence perfectly.

But speaking of it, the school really works hard to save face!
