Tech Hammer

Ning Wei glanced at the chat content and couldn't help but laugh.

The young people are really energetic. Even though they are drilled by the instructors at the military training base every day, they still have the energy to surf the Internet when they return to the barracks. And it seems that during military training, we can say goodbye to hard study for a while, and everyone's attention has become more divergent, and they have begun to pay attention to some discordant voices about Ning Ban on the Internet.

The thing is, the excellence of the children in Ningban is multi-dimensional. It’s not just about excellent test scores. Many children have already been exposed to programming when they were in junior high school, and by high school they are proficient in programming in multiple languages. These children will naturally log in to some more professional programmer forums to answer other people's questions or find some questions that interest them.

As a result, after the military training last night, a child was browsing the programmer forum and found someone making nonsense comments in the forum, commenting that Ningban was very popular, but in the end it could only cultivate some good writers... …

These words immediately made the child unhappy. He immediately took a screenshot of the forum speech and posted it to the group. As a result, the children in Ning class were very angry, and the consequences were serious. Everyone immediately registered an account to argue.

The forty people in a class, in the atmosphere of military training in the military camp, can easily arouse the spirit of unity, especially when Ning Wei has just stimulated them, so everyone is as brave as a wolf warrior, rushes to the forum and starts to follow That programmer theory.

He really made a post that no one paid much attention to and would go viral very quickly.

In particular, this kind of argument can easily reveal the identity of the children in Ningban, and even get angry out of the circle...

It just so happens that the time for the military training for freshmen at Yanbei University is not a secret. It is listed on the official website. Combined with the fact that at this time, Ningban students could still use the equipment to argue with a programmer on the forum, which immediately caused another voice on the Internet: "Is the current military training in institutions of higher learning just a formality? Why can students in the Ningban class still have access to the Internet during the completely closed military training? Can't today's students live without their mobile phones?"

Now the students in Zi Ning's class were even less calm. After all, they still take military training very seriously every day, and every time they surf the Internet, they are in the barracks, and many of them carry mobile phones to facilitate the search for information and study. Why is it not strictly related to military training?

So the children in Ningban discussed in the group how to deal with this kind of public opinion and rectify Ningban's name, so the group chat was of course very lively.

Of course, Ning Wei is not the only teacher in Ning's class group, but none of the classroom teachers have joined yet. Now apart from Ning Wei, only Zhou Yanping and Lucy Ron are in the group.

The ideological guidance of students is Lucy Rowan's main responsibility, and this Western beauty is indeed very competent. She has already become involved with her classmates in the group, discussing what everyone should do to make the outside world understand Ning. Shut up Ben's questioning.

The problem is that Lucy Rowan has only arrived in China for less than half a year. The long-standing Western ideological education system makes her not very in tune with the Chinese education philosophy. If she is a traditional Chinese counselor, she will definitely hope to turn it into a big deal. Small, make it a trivial matter. Educate these children that as long as they ignore those messy remarks, the situation can be calmed down. By the way, it can also educate children. As long as they study hard and achieve success in the future, those who once questioned Ning Ban will be speechless, thereby stimulating children's enthusiasm for learning.

But Lucy Rowan obviously does not have this style. Her idea is obviously not to make the big thing trivial, but to fight back if the children feel they have been slandered. What Ning Wei feels is to let those who are on the Internet have to fight back. Those who talk nonsense know that the excellence of the children in Ningban is not something that any cat or dog can question. It is naturally very easy to agree with this group of half-grown children.

So the group was really lively. After all, for the children in the Ning class, the counselors represented the government. Once the enthusiasm was aroused, it would be difficult to extinguish it.

Ning Wei regretted setting the group chat to do not disturb. Who would have thought that such an episode would happen when he was about to ask for leave?

"What's wrong?" Tian Yanzhen asked when he saw Ning Wei taking out his phone and looking through the chat history.

"It's okay, I will take care of it." Ning Wei replied without changing his expression.

"Show me!" Tian Yanzhen demanded.

Everyone has put a lot of effort into Ningban, including Tian Yanzhen, and naturally they will not underestimate any internal problems in Ningban.

Soon, Tian Yanzhen also roughly understood the content of the chat in the group, and then the two of them looked at each other in silence.

"Is this what you said about arranging everything in Ningban? Do you understand now? Education is no small matter! Forty outstanding children gather together every day, and anything can happen. We are still in the Internet age, so fart If the matter is amplified on the Internet, it may cause public opinion. How dare you hide in the laboratory for three months?" Tian Yanzhen glared at Ning Wei and asked.

"You also said that this is a big deal. I promise that this matter will be resolved properly before going to the laboratory tomorrow." Ning Wei immediately patted his chest and said.

"Also, I have no objection to your recommendation of Lucy to be the deputy counselor of Ningban, but should you talk to her? Or should you guide the children to focus on their studies? Let Ningban students go to the Internet to talk nonsense. What kind of education method is this? Should this idea be changed?" Tian Yanzhen asked again.

Although Ning Wei always complained about Lucy Rowan unconsciously when he was getting along with her, as the counselor he recommended, Ning Wei still felt that he had to be on Lucy's side.

So Ning Wei immediately said: "Director Tian, ​​you don't understand this. Children do need correct guidance, but this cannot be said to be a problem with Lucy's education methods. After all, Lucy is mainly responsible for the children. Emotional guidance. Regarding some incorrect voices, we should use an academic attitude to deny them. I think there is nothing wrong with this idea. We must have a spirit of truth-seeking when doing scientific research. Through some gossipy things, it is said that the children in Ningban are not If you take military training seriously, I think it’s understandable if they want to refute it.”

Tian Yanzhen glanced at Ning Wei, took a deep breath, and said seriously: "Okay, but Ning Wei, since this class is named Ning Class, you have to take responsibility."

Ning Wei immediately nodded and said: "Don't worry, Director Tian, ​​I said I would handle this matter perfectly, and I will definitely do it. When have I ever let you down?"

Tian Yan really didn't dare to answer this.

Really, Ning Wei has never let him down, but in many cases the shock even exceeds the surprise.

"Um, as you said, handle it perfectly. You won't cause any trouble, right? You must know that you are now a professor at Yanbei University. Every word and deed represents the image of Yanbei University. You can't do what you did when you were a student. That's all." Tian Yanzhen explained seriously.

He was really afraid that something would happen if Ningwei got serious.

"Don't worry, Director Tian. I am knowledgeable, interrogative, careful and discerning. I will definitely strictly demand myself in accordance with the school's regulations. I will definitely not do anything too excessive. I will never let you down." Ning Wei immediately promised road.

"Okay, go ahead. In any case, deal with the children's emotions well. Hey, this military training is not a worry. I will pay attention to it." Tian Yanzhen gave the final explanation.

…

Ning Wei turned around and returned to his office.

I still feel a little depressed.

It's not only the youthful spirit, but also the mood of anyone who encounters such an unreasonable disaster will not be too happy.

But Ning Weidao really doesn't think there is anything wrong with Ning class students. It's human nature to check their phones after military training. Ning Wei has also experienced military training. During the day, he has to stand in line and walk forward, and often has to gather urgently at night to sing cheers. In fact, for students, the intensity is not low. After all, military training for college students is not to take these things that just happened in high school. Graduates are directly trained to become regular soldiers.

So after returning to the dormitory, it is normal to play with the mobile phone.

Moreover, Ningwei also asked March to crawl directly on the programmer forum to collect the postings of students before the incident. Basically, they were concentrated between 9pm and 10pm, which was very reasonable in terms of time.

After a busy day, a group of adults still like to take a rest on the sofa during this time, browsing on their mobile phones, not to mention that these children are also logging into professional knowledge forums instead of using their mobile phones to open short video software and games. This kind of self-discipline even exceeds that of many adults.

So there is nothing wrong with your own children, but it is naturally others who have problems.

Ning Wei took a look at the ID of the forum that caused the hot topic. The account was registered 5 years ago. He mainly hangs out in the Java area. Obviously, this is a programmer who mainly does Java. Ning Wei took a look at the ID of the forum that caused the controversy. It took half an hour to record the post, but Ning thought he could probably determine the whole story.

This is a novice programmer five years ago. After completing the training class, he spent five years gaining some experience and insights in JAVA development. Now he should be doing software development work in a private network technology company that mainly does outsourcing. .

And this is not the first time this talent has complained about Ning Ban.

When Hua Qing formed the smart class, this guy complained about it, but Yao class didn't. The main reason was that he probably hadn't entered the industry yet when Yao class was formed. Of course, the last time he complained about Zhiban, there was no response. Probably no one paid attention to him. There were only a few arguments under the topic. The two sides argued for a few words, but people ignored him. Unlike this time, the children in Ningban collectively He went out and was noticed by interested people, so the topic went out of the circle.

Probably because this ID has helped many people in normal times, there are still many Java programmers in the forum speaking for him this time. Everyone was arguing and going back and forth. Ning Wei is quite helpless about this.

Many of the rhetoric were actually sophistry, but the students in the Ning class were obviously very angry at this kind of rhetoric, but they were unable to refute it. For example, regarding publishing papers, it is indeed undesirable to publish papers just for the sake of publishing papers, but normal scientific research does require publishing papers. After all, cutting-edge papers play a huge role in the transmission and collision of ideas.

Especially for those who are new to the industry, many research results will be wasted without summarizing previous papers.

Therefore, it is naturally right not to only focus on thesis, but the so-called academic school is a bad thesis. The misinterpretation of Ning Wei in the admissions video "Ningban will teach Yaoban and Zhiban how to do things in the future" is to make the children of Ningban always have a bad thesis in the future. Misinterpreted Ning Wei's meaning.

Don't say this to the students in Ning's class. Ning Wei was a little angry when he saw it. Although he also had a bad past and even considered the unfeasible problem of how to publish top journals until the school went bankrupt, he arrived at Yan After Peking University, I have been very restrained.

If you really want to raise your status by writing a fake paper, you would rather brag for him. If you don't talk about it for a year, it is really not a big problem to publish more than a dozen papers in the top journals. The field he is currently researching is at the forefront of the forefront, and any innovation is worth publishing a paper. Therefore, not only can Ningwei publish it openly, but scholars in those fields are too embarrassed to criticize him.

From this point of view, Ning Wei has shown enough restraint on the issue of publishing papers. Just like what he told Tian Yanzhen, he also hopes that his students in the future can focus on making some achievements. If they produce results under his hands, they will be more favored than if they produce papers.

So now Ningwei feels that this matter must be dealt with by the group of people who are causing the trouble, at least to make the children like Ningban feel at ease.

Although Ning Wei has never studied educational psychology, after reading the chat records between Lucy Rowan and the children, it is easy to conclude that the handling of this incident must be consistent with the demands of the students, which will be more motivating. The children have a sense of identity and honor for the Ningban group. As a spiritual leader, he really needs to make these children realize how rewarding learning is.

So Java...

Ning Wei looked at March on the screen and asked, "March, you should be familiar with Java, right?"

"Meow, actually I am familiar with all current programming languages." The kitten looked very proud.

"That's good. I want to keep these Java programs busy. At least during this time, I won't have time to argue with the children in our Ning class online. I don't have much research on Java, but I know that any programming language will definitely have some imperfections. If you are familiar with the place, you should understand it very well, right?" Ning Wei asked casually.

March on the screen lazily raised her paw, and then a list was called up.

Ning Wei glanced at it and found that it was really good to have an assistant like March. He wished he could pull this cute kitten out of the screen and stroke it hard.

In fact, the list is not a big deal, it is just a bunch of vulnerabilities that can be exploited and attacked, and the list made in March is very considerate. It ranges from high-risk vulnerabilities that may have a serious impact to low-risk vulnerabilities that have less serious impact. Clearly.

Low-severity 0Day vulnerabilities are actually not important. For the official, routine updates can solve them. High-severity vulnerabilities can keep everyone busy for a while, especially the vulnerabilities that exist in commonly used libraries. Once exposed, it will be sufficient for Java programs. The members have been busy for a while, at least they will be so busy that they will never have time to chat on the forum again.

So you still have to choose the high-risk one...

Of course, Ning Wei is not a hacker. Ning Wei will not do anything illegal and criminal. The crime of destroying computer systems has already made everything clear. But for an excellent programmer, telling the official that their program has serious basic high-risk vulnerabilities can be rewarded.

Generally speaking, you can get bonuses by proactively providing high-risk vulnerabilities. Of course, the bonus is not important to Ning Wei. He just browsed the list briefly, then selected one of the extremely basic high-risk vulnerabilities, opened the Java environment, and confirmed that the vulnerability existed. , and then opened the WeChat group.

"I already understand the issues that students are paying attention to. Don't be angry. I will solve this matter. How to solve it specifically? You can pay attention to my speech on Weibo in the evening. But you should not pay special attention to Weibo. As the old saying goes, for me, Weibo is just a channel to express my voice, and it is enough to be useful. For you, you only need to know that this matter has been resolved, and then focus on studying."

"Studying is the most important thing for you at this stage. Whether you can stay in Ningban depends on the answer sheets you turn in for the final exam. So I still hope that everyone will not continue to compete individually on the Internet after I deal with this matter. , it makes no sense. When I was studying at Jiangsu University, Mr. Kong, the dean of the School of Mathematics at Jiangsu University, once said something to me. I will pass it on to you here. On your way to the top, those noises should stop you. Come down and take another look, you are the losers. Let’s encourage each other.”

After sending it, no one responded, which is normal.

It's past lunch break now, and the students should be standing in military posture at the base, but everyone should be able to see his reply by the evening, and that's enough.

After sending the message on WeChat, Ning Wei logged into Oracle's official website and sent an email directly to the technical mailbox.

"Hello, Java maintenance team, I am Ning Wei. My team discovered a serious infrastructure vulnerability in Java. Specifically, there is a JNDI injection vulnerability in log4j-2, the basic log framework of Java. This vulnerability is extremely dangerous and attacks The attacker only needs to enter a piece of code to the target, and does not require the user to perform any operations to trigger this vulnerability, allowing the attacker to remotely control the server to execute arbitrary code. It is recommended to fix it as soon as possible."

Ning Wei sent the same email not only to Oracle, a JAVA language company, but also to domestic network security companies, as well as companies such as Huawei Cloud, Xiaoli Cloud, and Penguin Cloud that provide server support for countless companies.

Finally, Ning Wei opened Weibo and started editing text.

"Thank you very much for your attention to Ningban. Ningban is a new class group and there must be shortcomings in one way or another. But one thing is that every child in Ningban is extremely outstanding. I mean at any level. As one of the instructors of Ningban, I hope everyone can be less harsh and more understanding. After all, they are still children. If there is anything they don’t understand, they can come to me. In addition, I already know the cause of this matter. As a Java engineer, what I want to say is that if you are too busy, I will keep you busy for a while. If you still complain about our Ning class without any basis next time, do you think I can keep you busy for a while? whole year?"
