Hammer of Technology

A laboratory that only needs a few people to cooperate and play well can truly match the advantages of March.It is no longer necessary to manually enter data. After collection, all data will be directly read by the intelligent system of March through the modified equipment, and then incorporated into the database to optimize its mathematical model, and then in the next laboratory .

This is actually similar to the experiments conducted in the perfect simulation environment constructed every day in March, except that the simulation is completely completed through supercomputer calculations. Now that the laboratory is completed, it needs to be verified in reality.

Of course, the most important thing for Ningwei is that the completion of the first area of ​​the laboratory is that he finally has a good reason to ignore the trivial matters of the school and go to the laboratory for a period of time.

"What? You're going to the lab for three months at this time? Aren't you? Ning Wei, the military training will end next week, and Ning's class will officially start. Are you going to the lab at this time?" Tian Yan is really obvious I think Ning Wei is a little noisy.

"Well, we have to go. Billions have been poured in, and some results must be produced quickly. Investors must feel a little hopeful. Otherwise, next time I have any excessive demands, people will ignore me." Ning The reasons given for this are very tenable.

"No, I have no objection to doing research, but you have been away for three months. What do you mean by not contacting you if you have nothing to do? Even if the laboratory moves, it is still in the capital. I won't say that I will come back every day." , you can come back every few days? You are going to speak on stage at the school's welcome ceremony, and you don't plan to talk to the children before class starts?" Tian Yan really felt a little headache.

"I won't give a speech at the orientation ceremony. People may not like what I say, and you should also open it. I don't have much pursuit of publishing papers now. I think it's better to be honest than to write so many papers in top journals. I am making something out. I will ask my students to do the same in the future. However, it is not appropriate to enlarge the speech to the whole school."

"As for the Ning class, everything has been properly arranged. I don't have to meet with you when the class starts, I have already talked in the group. You don't know, I told them, let They must study hard, because the exam questions in the Ning class are very difficult, and there is a 30% elimination rate at the end of the freshman semester. A bunch of little guys are very unconvinced, and they are all expressing their determination to pass the exam. Give me some points Look at the color."

Ning Wei explained.

As he said that, he took out his mobile phone and called up WeChat, preparing to prove it to Tian Yanzhen.

But found that the class group of Ning class was quite lively.

This surprised Ning Wei. It is still during the military training period for freshmen. Generally speaking, the military training requirements of Yanbei University are quite strict. If you leave the barracks with your mobile phone, it is likely to be confiscated. The energy is exhausted, these children are really full of energy, and they are still in the mood to speak in the group?

What are you talking about? !

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

330 When I get busy, I don't have time to talk about it

Ning Wei glanced at the content of the chat, and couldn't help but burst out laughing.

Young people are indeed full of energy. Even though they are trained 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 the military training, we can temporarily bid farewell to hard study, and everyone's attention has become more divergent, and we 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 that the test scores are excellent, there are also many children who have been exposed to programming in junior high school, and are already proficient in programming in multiple languages ​​​​in high school.These children will naturally log in to some more professional programmer forums on weekdays to answer other people's questions, or find some questions that they are interested in.

As a result, after the military training last night, a child was visiting the programmer forum and found that someone was making a lot of quibbles in the forum, commenting that Ningban was very hyped, but in the end, he could only cultivate some good writers... …

This made the child unhappy immediately, and immediately took a screenshot of the forum speech to the group, so the children in Ningban were very angry, and the consequences were serious.Everyone immediately registered an account to argue.

A class of No. 40 people, in the atmosphere of military training in the military camp, can easily arouse that spirit of unity, especially just stimulated by Ning Wei, so everyone is as brave as a wolf warrior, rushed to the forum and started to talk That programmer theory.

Lively heated up a post that logically no one paid attention to, and would soon sink.

In particular, this kind of debate can easily expose the identities of the children in Ningban, and by the way, get out of the circle...

It just so happens that the time for Yanbei University’s military training for freshmen is no secret. It’s available on the official website. Combined with the fact that at this time, the students in the Ning class can still use the equipment to argue with a programmer on the forum, it immediately provokes another voice on the Internet: "Is the military training in institutions of higher learning now just a formality? Why can the students in the closed military training be able to access the Internet? Are the current students unable to live without their mobile phones?"

Now the students in Class Ning were even more restless.After all, their military training is still very serious every day, and every time they surf the Internet, they are in the barracks, and many people carry their mobile phones for the convenience of querying information and learning. Why is it related to the military training being not strict?

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

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

Guiding the students' thoughts belongs to Lucy Ron's main job, and this western beauty is indeed very competent. She has already gotten along with the students in the group, discussing what everyone should do to make the outside world feel better about Ning. Ban's questioning shut up.

The problem is that Lucy Ron has only been in China for less than half a year. The long-standing Western ideological education system has made her not very compatible with the educational philosophy of Chinese people. If she is a traditional Chinese counselor, she must hope to turn the big thing into a big deal. It's small, it's a trivial matter, and educating these children can calm down the situation as long as they don't pay attention to those messy remarks.By the way, it can also educate the children. As long as they study hard, when they have achievements in the future, they will be able to make those who questioned the class have nothing to say, thus motivating the children's enthusiasm for learning.

But Lucy Ron is obviously not in this style. Her thinking is obviously not to make big things smaller, but the children feel that they have been slandered, so they have to fight back. It gives Ning Wei the feeling that it is necessary to let those who are on the Internet Nonsense people know that the children of Ningban are excellent, and not all cats and dogs can question them.This kind of argument is naturally very easy to reach agreement with this group of half-grown children.

So the group was really lively. After all, for the children in Ningban, the counselor represented the officialdom. Once the enthusiasm was aroused, it would definitely be difficult to extinguish it.

Ning Wei regretted setting the group chat to Do Not Disturb. Who would have thought that such a small episode would happen when he was about to ask for leave?

"What's wrong?" Seeing Ning Wei take out his phone and keep flipping through the chat records, Tian Yanzhen asked.

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

"Show me!" Tian Yanzhen demanded.

Everyone put a lot of effort into Ning Ban, including Tian Yanzhen, and naturally they would not underestimate any problems within Ning Ban.

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

"This is what you said you have arranged everything in Ningban properly? Do you understand now? Education is no small matter! Forty excellent children gather together every day, and anything can happen. It's still the Internet age, so be a little bit bigger After the incident is magnified on the Internet, it may cause public opinion. How dare you hide in the laboratory for three months?" Tian Yanzhen glared at Ningwei and asked.

"You also said that this is a big deal, I promise, before going to the laboratory tomorrow, I promise to solve this matter properly." Ning Wei said immediately, patting his chest.

"Also, I have no objection to you recommending this Lucy as the deputy counselor of the Ning class, but should you talk to her? Or should you guide the children to focus on their studies? Let the students in the Ning class go to the Internet to talk nonsense What kind of education method is this? Shouldn’t this way of thinking be changed?” Tian Yanzhen made another point.

Although Ning Wei always complained about this woman unconsciously when getting along with Lucy Ron, but as the counselor recommended by him, Ning Wei still felt that he would stand by Lucy's side.

So Ning Wei immediately said: "Director Tian, ​​you don't understand this. The children do need correct guidance, but it can't be said that there is something wrong with Lucy's education method. After all, Lucy is mainly responsible for the children's education. Emotional guidance. For some incorrect voices, we should use an academic attitude to deny them. I think there is nothing wrong with this idea. We must have the spirit of seeking truth in scientific research. Through some guesswork, we can say that the children in Ningban did not Serious military training, I think it is understandable that they want to refute."

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

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

Tian Yan really didn't dare to answer these words.

Really, Ning Wei has never let him down, but most of the time the shock even outweighs the surprise.

"Well, what you said is handled perfectly, so you won't cause any trouble, right? You must know that you are now a professor at Yanbei University, and every word and deed represents the image of Yanbei University. You can't be like you were when you were a student. What do you want to do? Just do it." Tian Yanzhen said seriously.

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

"Don't worry, Tian Dao, erudition, interrogation, prudent thinking, discernment, I will definitely strictly demand myself in accordance with the school's regulations. I will definitely not do too much. I will never let you down." Ning Wei immediately promised road.

"Okay, you go. In short, handle the children's emotions well. Hey, this military training is not worry-free. I will pay attention to it." Tian Yanzhen finally confessed.

……

Ning Wei turned around and returned to his office.

The mood is still a little depressed.

It's not just the youthful spirit, but anyone who encounters such an indiscriminate disaster will not feel too refreshed.

But Ning Wei really didn't think there was anything wrong with the students in Ning's class. It's human nature to look at their mobile phones after military training.Ning Wei has also experienced military training. During the day, he has to stand in line and walk forward. In many cases, he has to gather urgently at night and sing songs. In fact, for students, the intensity is not small. Graduated students are directly drilled into regular soldiers.

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

And Ning Wei also asked March to directly crawl the posting events of the students before the event fermented on the programmer forum. Basically, they were concentrated between nine o'clock and ten o'clock in the evening, 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 and brush their mobile phones, not to mention that these children are still logging in to professional knowledge forums instead of using their mobile phones to open small video software and games. This self-discipline has even surpassed that of many adults.

So there is no problem with my own children, and it is naturally others who have problems.

Ning Wei roughly looked at the forum ID that caused the hot spot. The account was registered 5 years ago, and the main places where he was mixed up were concentrated in the Java area. Obviously this is a programmer who mainly does Java. By the way, Ning Wei took a look at the forum ID that caused the war Posting records, it took half an hour for Ning Wei to probably be able to determine the whole story of this matter.

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

And it's not the first time this talent has complained about Ning Ban.

When Huaqing established Zhiban, this dear friend complained about it, but Yaoban didn't complain, mainly because he probably hadn't entered the industry when Yaoban was formed.Of course, the last time I complained about the wisdom class, it didn't cause any repercussions. Probably no one paid attention to him. There were only a few rebuttals under the topic. It was dispatched, and then it was noticed by interested people, so the topic went out of the circle.

Probably because this ID has helped many people, so this time there are still many Java programmers speaking for him in the forum.Everyone is arguing that you come and go.Ning Wei is quite helpless about this.

A lot of rhetoric is actually a sophistry with rhetoric, but the students in Class Ning were obviously very angry with this kind of rhetoric, but they were powerless to refute.For example, regarding publishing papers, it is indeed not advisable to publish papers just for the sake of publishing papers, but normal scientific research work does require publishing papers.After all, cutting-edge papers have played a huge role in the transmission and collision of thinking.

Especially for new entrants, there is no summary of previous papers, and many research results are wasted.

So it’s true that it’s not only thesis theory, but the so-called academic school is the water thesis. The misinterpretation of Ning Wei’s admissions video that “Ningban will teach Yao Ban and Zhiban to do things in the future” is to let the children of Ningban always be water thesis in the future. Distorted the meaning of Ning Wei.

Let alone the students in Ning’s class, Ning Wei was a little angry when he read it. Although he also had a bad past, and even considered the unfeasible problem of how to publish the top publication until the school went bankrupt, he went to Yan Peking University has been very restrained.

If you really want water papers to raise your value, it's not that Ning is bragging for him. If you don't say too much in a year, it's really not a big problem to publish more than a dozen top journal papers.The field he is currently researching belongs to the frontier of the frontier, and any innovation is worth publishing a paper, so Ning Wei can not only publish it openly, but scholars in those fields are not ashamed to call him stupid.

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

So now Ning Wei felt that the group of people who provoked the trouble had to be dealt with, at least to make the children of Ning Ban feel at ease.

Although Ning Wei has never studied educational psychology, but after reading the chat records between Lucy Ron and the children, he can easily come to the conclusion that the handling of this incident must be in line with the demands of the students. The children have a sense of identity and honor for the collective Ningban.As a spiritual leader, he really needs to make these children realize how great learning is.

So Java...

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

"Meow, I'm actually familiar with all programming languages ​​at this stage." The kitten was very proud.

"That's good. I want to keep these Java programs busy. At least I don't have time to chat with the children of our Ningbo class online. I don't have much research on Java, but I know that any programming language will definitely be less than perfect. If you are familiar with the place, you should understand it very well, right?" Ning Wei asked casually.

March on the screen lazily raised its paw, and then a list was called out.

Ning Wei glanced at it, and sure enough, having a little assistant like Sanyue is really nice, making him wish he could pull this cute little kitten out of the screen and rub 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, from high-risk vulnerabilities that may have serious impact to low-risk vulnerabilities that are not so serious. Clearly.

Low-risk 0-Day vulnerabilities are actually not important. For the official, routine updates can solve them, and high-risk vulnerabilities can keep everyone busy for a while, especially the vulnerabilities that exist in commonly used libraries. Once exposed, they are enough for Java programs. The members have been busy for a while, at least they can be so busy that they never have the leisure to go to the forum to chatter.

So you still have to choose high risk...

Of course, Ning Wei is not a hacker, and Ning Wei will not do illegal and criminal things. The crime of destroying the computer system has already arranged everything clearly.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 for actively providing high-risk vulnerabilities. Of course, bonuses are not important to Ningwei. He just browsed the list, and then selected one of the extremely basic high-risk vulnerabilities, opened the Java environment, and confirmed the existence of the vulnerability. , and then opened the WeChat group.

"I have already understood the problems that the students are concerned about. Don't be angry. I will solve this matter. How to solve it? You can pay attention to my speech on Weibo at night. But everyone should not pay special attention to Weibo, or That old saying, for me, Weibo is just a channel to express my voice, it’s enough if it’s easy to use, for you, you just need to know that this matter has been resolved, and then you can focus on your studies.”

"As the old saying goes, study is the most important thing for you at this stage. Whether you can stay in Ningban depends on the answers you hand in in the final exam. So I still hope that everyone will not continue to be in the class after I have dealt with this matter. There is no point in online personal matchmaking. When I was studying at Jiangda University, Mr. Kong, the dean of Jiangda School of Mathematics, once said a word to me, and I will pass it on to everyone here. There are some noises that make you stop and take a second look, you all lost. Let’s encourage each other.”

After sending, no one responds, which is normal.

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

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

"Java maintenance team, hello, I'm Ningwei, my team discovered a serious infrastructure vulnerability in Java, specifically, there is a JNDI injection vulnerability in the basic logging framework log4j-2 of Java. This vulnerability is extremely dangerous. Only The attacker only needs to input a piece of code to the target, and the vulnerability does not need to be performed by the user, allowing the attacker to remotely control the server to execute arbitrary code, and it is recommended to fix it as soon as possible.”

The same email was not only sent to Oracle, a JAVA language company, but also to domestic network security companies, as well as Huawei Cloud, Xiaoliyun, and Penguin Cloud, which provide server support for countless enterprises.

Finally, Ning Wei opened Weibo and began to edit the text.

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

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

331 Chain Reaction

A group of children from Ningban almost rushed into the barracks assigned to them after the whistle for disbanding sounded.

Because very angry!

But this is a special war. The two warring parties need to argue on the Internet. Regardless of whether the winner can be won or lost in the end, there must be an explanation.

The time spent queuing up in the square and standing in a military posture in the afternoon is enough time for many children to think of many logical rhetoric. They feel that posting these rhetoric on the Internet, netizens will definitely find no loopholes, and it will also change the outside world's perception of Ning. class understanding.

however……

"Wow, Professor Ning made a move, Professor Ning made a move..."

The kid who got the phone first suddenly started cheering.

Everyone was excited now, and quickly opened the WeChat group, saw Ning Wei's message to them, and then opened Weibo impatiently.

Those who did not have Weibo on their phones quickly gathered around the students who had already installed Weibo on their phones, and began to see what Ning Wei said on Weibo.

Seeing Ning Wei declaring that the Ning class is the best, everyone puffed up their chests intentionally or unintentionally, and then they saw Ning Wei's domineering declaration...

According to the self-translated words in the children's brains, it is: "You jumping clowns, dare to provoke my students, you are dead..."

The only question is, what exactly did Professor Ning do?Didn't say it on Weibo?

"Everyone, look at the comment area!!!" Someone in the wechat group immediately reminded.

Clicking on the comment section of Weibo, the children were stunned... especially the comment with the most likes in the front row.

"Don't worry, we are convinced, no matter whether that guy is convinced or not, we are really convinced. Ning Ban will be the domain of gods, and you are the mentor of gods. I just ask you to show your hand and let us live. Programmers are really hurt. Sorry!"

"The emergency notice has come. I just finished the meeting. Today must be all night. I don't know if I can rest tomorrow. Of course, I really don't blame Professor Ning. I just want to know whether it is God who made you angry. I want to get that brother out and serve you a drink."

"Who? Who is that guy? Professor Ning, don't get angry with that guy. The main reason is that you have learned too much java. It's normal to have a few things that start with S and end with B. From now on, Class Ning will be in my mind." Eternal God. Please calm down!"

……

The children in Ningban had question marks on their faces.

So, what did Professor Ning do?Why is Weibo full of begging for mercy?

Fortunately, this matter is actually very big, and Ning Wei directly notified almost all well-known network security companies and large cloud service providers in China, and soon the news came out.

Just because a developer suspected of using the java language picked up trouble on the programmers forum and said something wrong about Ningban, Ningwei directly notified the Java official, China's mainstream network security companies, and cloud service providers of a hidden danger the next day. big hole.

According to an expert from a well-known network security company in China, Ning Wei notified their vulnerability, the affected devices are calculated in billions and spread all over the world. The most frightening thing is that if this vulnerability is exploited, the device may be unknowingly hacked control……

The vulnerability reported by Ningwei is definitely the most serious vulnerability exposed in Java in recent years.So unfortunately, all java developers are really busy these days, so busy that they crash.
