Hammer of Technology

It is actually possible to continue counting, but it is not necessary.

It's just that the child doesn't know how to call Dad, which still makes him, a developer, a headache and is happy.

The headache is because there is a lot less fun, and the joy is because it at least shows that the learning of numbers is not a simple repetition. Of course, if there are small personality factors in it, he will be even more happy.

As we all know, the hardware and software of computers have no personality. AlphaGo can abuse professional players in Go, but it cannot be asked to say to other players: "Real food."

Countless sci-fi works give the ultimate definition of artificial intelligence that it can have limited but independent thoughts and emotions similar to human beings, but it is obviously difficult to achieve this in the face of a thinking mode that is confined by binary.

Fortunately, Ning Wei is not in a hurry, and can train slowly in March.

Just like humans trained AlphaGo to become the overlord of the Go world, Ning Wei also has the confidence to train Sanyue to be a sensible little milk cat.

This also makes Ning Wei never tire of it.

Until the door of the private room was knocked.

"Please come in."

Yu Xingwei walked in with a lunch box.

"They all said that you must have rested and didn't go out at all, so I knew you must have not slept! They brought you a special meal." Yu Xingwei said as soon as he entered the door.

"Thank you, Brother Yu." Only then did Ning Wei feel that he was really hungry.

Putting the lunch box on the table, Yu Xingwei glanced at March on the table, and said hello: "Hey, March, you're out again."

On the screen, Sanyue squinted her eyes, then looked away arrogantly, lowered her head and focused on licking her fur...

"Brother Yu, are you still not going to rest?" Ning Wei asked casually as he opened the lunch box.

"Don't mention it, a group of people refused to let me go, saying that I don't need to sleep because I am an iron man, and I have to invite them to dinner today." Yu Xingwei said with a sullen expression: "Okay, I'll go first, and the group of people can't see you." Others are good guys!"

"Huh?" Before Ning Wei had time to ask which group of people were so hateful, even forcing them to invite them to dinner without time for jet lag, Yu Xingwei had already left in a flash.

In fact, Yu Xingwei didn't really want Ning Wei to ask this question, after all, there are some debts that must be repaid after all.

While eating, the phone vibrated. Ning Wei opened it and saw that it was a new email.

He opened his eyes, then froze.

Um?The paper was rejected?

At the moment when he saw the rejected manuscript, Lu Dongyi's words flashed in Ning Wei's mind. It is very difficult to get into the top four journals of mathematics...

It really is difficult.

Instead of asking him to make minor revisions, or even major revisions, but to be rejected directly?

Well, I have to say that this is also a very novel experience, after all, this is the first time in my life that I have been rejected.

Fortunately, there is a reviewer's reply in the rejection email.

Ning Wei began to carefully study the reasons for being rejected, and was actually a little confused after reading it.

Because this is not like an opinion given by a senior reviewer. Where is the problem, are you giving your own opinion?The range of existence can be continuously extended, and there are serious demonstration problems so broad that one sentence can be written in the reasons for rejection of top journals?

Before Ning Wei came back to his senses, the mailbox started to prompt again, and there was another new email.

Ning Wei clicked on it subconsciously, and then saw the email sent to him by the editor-in-chief of the "Journal of the American Mathematical Society".

After reading the email carefully, Ning Wei realized something.

Then he opened WeChat, found Lu Dongyi, and sent a message: "Brother, our paper was rejected."

After about half a minute, Lu Dongyi replied with a message: "?"

Ning Wei thought about it, and did not choose to send the reasons for rejection, but sent the editor-in-chief's email with the last signature hidden.

This time he didn't make him wait long, and Lu Dongyi replied: ""Mathematics Annals" is jointly published by Princeton University and the Princeton Institute for Advanced Study; "New Advances in Mathematics" is published by SpringerVerlag; "ActaMathematica" is published by the Royal Swedish Academy of Sciences Mittag- The Leffler Institute was founded. After reading this passage, I probably understand why Smith’s paper did not choose the four top journals but "Nature."

Ning Wei looked at this reply, but before he could figure out how to reply, the phone rang, and the senior brother called directly.

"Hello, brother."

"Well, have you returned home?"

"Yeah, I just went back to school in the afternoon, and then I received a reply email."

Speaking of this, the other side was silent for a moment, and said: "Actually, you are not the first to encounter this kind of thing. I have a friend who spent about a year and a half in the United States studying for a Ph. D. and worked more than ten hours a day. , wrote hundreds of thousands of lines of Coq. Under normal circumstances, such a large workload may require ten people to write for a year. His supervisor is very positive about his research results and believes that it has the potential for breakthrough results. So he voted for PLDI, also the top conference in his field."

"The result was also rejected. The situation at the time was that other reviewers passed, but one reviewer persuaded all reviewers to reject the manuscript on the grounds of unfair evaluation of a related work in the paper. Later, he switched to OSDI, The same was rejected. The reason is similar, he was worse than you because some reviewers made his source code public at that time. This is very unfavorable to him.”

"It wasn't until he voted for POPL that he finally passed it. But at that time, the team that had been rejecting his manuscript had already published a paper on the same research topic, which was widely praised. This matter was a big blow to my friend at the time, but he finally accepted it. walked out."

Ning Wei thought for a while, and then said: "Brother Lu, isn't it? That's all for your friend?"

Lu Dongyi did not directly answer this question, but continued: "Do you remember that during the Chinese New Year, you asked me what unspoken rules there are in the academic circle? I didn't want you to doubt the path you insisted on, so the answer is There are no unspoken rules in the academic circle. But sometimes it is not like this. This kind of thing may not be many, but as long as there is competition in the field, it is inevitable. Even in the top academic circle.”

"My friend was actually quite unlucky, but he was also lucky. Although his thesis in this direction was blocked, his supervisor probably felt guilty about his setbacks, let him graduate early, and helped him find a good one. Then he also resolutely left the academic world and switched to the industrial field, and he is doing well now. Of course, this is not to make you give up, but to tell you that when encountering such a thing, you must first fight for it. No matter what, you can have a clear conscience."

"In the same way, don't lose your confidence in doing academics because of some things that are destined to be shady. As said at the end of that email, the fact that you can receive this email is enough to show that someone is supporting you unconditionally , more people know the value of your paper. After all, we are still in a relatively wild stage of supercritical analysis at this stage.”

……

Quite a heavy topic.

But after chatting with Lu Dongyi, Ning Wei actually felt much lighter.

Sure enough, where there are people, there are rivers and lakes...

"Senior brother Lu, do you know who this respected gentleman in the field is?" Ning Wei finally asked.

"From the above description, I can probably guess it. You can search for the name Lucasson Friend. But how should I say, if I remember correctly, the old gentleman should be almost 60 years old .”

"Oh, brother, do you mean that half of the old man's leg has been buried in the soil, and he should receive a wreath after a few days of jumping?"

Lu Dongyi: "..."

"It doesn't matter if you don't vote for the four top journals in mathematics, in fact, you can directly vote for "Nature" just like Smith."

"I think so too."

"Okay, little brother, I'm sorry."

"Ok?"

"It seems that you shouldn't have given you the top four mathematics journals of science popularization."

"No, brother! I am full of fighting spirit now. Tagore once said that the most correct way to cure evil is to fight it! Don't worry, brother! Leave it to me!"

Ask for a monthly ticket for a single chapter

Double monthly pass, one vote now is worth two, and it will expire the day after tomorrow, so please give this seedling a few more monthly passes!

Although it may not be possible to add more codes today, but there are more monthly tickets this month, and the code words next month will definitely be full of motivation.

Moreover, according to the legend, if you get enough 3000 monthly tickets for the double monthly ticket period, you can unlock the author’s ability to change daily. I have always been skeptical about this legend, but because I haven’t experienced it, I really don’t know if it’s true or not. .

All experience comes from practice. It is said that once, in order to test whether pepper powder or chili powder was hotter on chrysanthemums, a friend specially smeared both powders on chrysanthemums, and then wrote a [-]-word test report.

So if we also get 3000 votes, I will know whether the legend of unlocking the author's ability is true or not, and then I will definitely share the truth with you...

that's all!

Finally, thank you for your support, thank you pudding!

122 The counterattack begins with defense

After hanging up the phone, Ning Wei quickly calmed down.

It was not the first time he had experienced unfair things, but this time like today, it still gave him a very special experience.

Because of the injustice in the past, he probably knew why, and had face-to-face contact with the person who imposed the injustice, but this time, everything was done in the air. Mr. Friend, never met.

But when the name came out of his senior brother's mouth, he had some impressions.

I still remember that when I was studying partial differential equations, the professor mentioned this name, and there will be no more.

Opening Baidu, Ning Wei entered the name, and soon got feedback.

Obviously, this is indeed a leader in the industry. One of the Fields Medalists in 1994, his achievement is partial differential equations. Some mathematical methods proposed by him have been included in the textbooks of partial differential equations in colleges and universities in various countries.

In addition, this gentleman is also a member of the American Academy of Sciences, a lifetime honorary professor of Princeton University, the vice president of the American Mathematical Association, a member of the Royal Swedish Academy of Sciences, and a member of the International Mathematical Union Committee...

A series of titles almost dazzled Ning Wei.

If it weren't for the email from the editor-in-chief, Ning Wei felt that he would never have thought that he would be able to connect with this kind of character who should live in the textbook.

But then again, if it weren't for a bigwig of this level, it would probably be difficult to influence the editor-in-chief of a world-class top journal.

After learning about the life of this legendary mathematician, Ning Wei carefully checked the paper again.

In fact, this mathematician is right in one point. If his paper is really imprecise, publishing it rashly will indeed have a detrimental effect on the entire academic world, especially if he proposes some new mathematics. Essay on ideas and solutions.If it is proved to be wrong after a period of time, all other papers in this field that have cited Ning Wei's paper during this period will be greatly negatively affected.

This is also the reason why mathematics journals are more strictly reviewed and the number of papers published each year is not too large.

After all, you can't believe that someone can get the correct result by citing a wrong thing. There may be such a coincidence, but it does not belong to the category of rigorous scientific research.

After checking the paper again and correcting a few grammatical errors, Ning Wei opened the submission system of "Nature" and submitted a manuscript to this world-class journal for the second time.

Of course, this is just the beginning. Ning Wei has already made up his mind that he will teach Lucasson Flender a good lesson in the future.

Of course, this will take some time.

After doing all this, Ning Wei did not rest immediately, but called up the source code of the turbulence algorithm from the computer.

Thanks to Lucasson Friend for teaching him this lesson, let him understand that even in academia not everyone is as beautiful and respectable as he imagined, so I am submitting an article on turbulence algorithm And before papers that need to use the algorithm source code, it is necessary to take some precautions.

He is still planning to teach others, but he doesn't want to be taught a second lesson.

Not to mention that the academic circle can be so stubborn, but when it comes to the application, it is a technology that is directly linked to an industry and real interests. If you continue to be honest, you will probably end up being eaten up to the point where there is nothing left. can be said.

The so-called patents and copyrights can only guard against gentlemen.After all, even if someone really infringes, he doesn't have the time and energy to go to court with them, and scientific researchers don't have that much free time.

So I can only let myself be a villain first.

The example Brother Lu gave has already explained everything.

It's also a good thing that brother Lu's friend met a mentor with a conscience. If he changed to a mentor with a dark heart, he would probably be eaten to death, right?

Of course, doing tricks in the source code is actually a test of your skills.

If someone really wants to steal the source code of a certain software product, many engineers will naturally analyze the code thoroughly before starting the next step.

Since not all paper reviewers are trustworthy, this step should not only be done, but also be done carefully.

After thinking for a long time, Ning Wei decided to add three layers of verification methods to the source code.

The first step is rather to add several equations that will have specific return values ​​under specific circumstances in the main function. If the source code is used directly without modification, he only needs to send a specific signal to the target device, and a set of fixed values ​​can be obtained immediately. The return value.

The second step is to decide to add a wave equation of standing waves to the source code.

Although simple, it is actually very confusing.

Standing waves are two types of waves that have the same frequency but travel in opposite directions.

When the fluctuating frequency is in his hands, if the turbulence algorithm is really pirated and this equation is not eliminated, then he can make the pirated software or equipment useless after simple calculations.

The hidden point is that after the turbulence algorithm simulates a physical space, it is necessary to explain various splashes, and the standing waves are mixed in it. If you are not very careful, it is difficult to distinguish its effect on the program.

The third step is the most complicated. Ning Wei decided to add Fourier series, Fourier coefficients and Fourier transform to the core code.

To put it simply, the time-domain signal is transformed into a frequency-domain function through Fourier transform, which stipulates that the time domain is a signal, the frequency domain is a function, and the spectrum is also in his hands.

This spectrum represents the three parameters of frequency, amplitude and initial phase of all cosine signals of different frequencies contained in the periodic signal, and these three parameters of each cosine represent all the information of this cosine.

If the turbulence algorithm is used directly without authorization, and the newly added code is not completely eliminated, it is basically equivalent to leaving a back door for Ningwei to do whatever he wants.

Ning Wei is not afraid of being exposed, because these functions can be said to be part of the turbulence algorithm.

For example, the standing wave is a supplement to the original waveform, and can also be used for secondary screening to determine illegal access data streams.

Equations for specific return values ​​can also be triggered at specific stages of the test phase to collect return data.

Adding Fourier series, coefficients and using Fourier transform can also be used to simplify the final calculation.

After making a rough plan, Ning Wei finally couldn't hold on anymore.

It's so sleepy...

Of course, it is impossible to add these things to the program by hand today.
