The lost Internet technology circle

随笔

https://blog.csdn.net/emprere/article/details/98860534

As early as a few years ago, some people said that programmers would be difficult to mix without management after the age of 35. Nowadays, because of the recent Huawei incident, it has been heated up, which obviously made people’s guesses many years ago. This year also happened to be the age for "retirement", so I wanted to take the opportunity to regret it. First of all, the point of clarification is that I have no intention to defame this IT industry. I just hope that you can recognize this industry more clearly.

What is called management? In the programmer's mind, management is actually very simple, that is, from writing code to not writing code, even if it is writing PPT, as long as you don't write code, it is management. To put it bluntly is to leave the circle of the code farmers. Why do everyone panic out of this circle? Let’s start with IT and the Internet industry.

This is a typical self-deprecating industry. People are taunting to leave, but new people are constantly pouring in. Note that this is not a siege. Those who quarrel to leave are not really wanting to leave, but more of helplessness. And self-deprecating. This kind of thing has appeared twice on a large scale in history, but IT and the Internet are different from the previous two.
The first was the period of the Industrial Revolution and the period of industrialization, with Britain and the United States being the most typical. At that time, large-scale crowds poured into dirty and dangerous mines. On the one hand, the factory was complaining about its bad situation, but on the other hand, there was a long queue at the registration office. Please note that no one forced these workers to work. They are all voluntary, and they have their own happiness. No matter how sad, they always seek happiness, although these humor is always black. The film "Modern Times" is a microcosm of the late industrialization era. Who are the descendants of these sad workers today? The answer is clear: it is the middle class in Europe and America.

The second was the national urbanization process after World War II. Taking China as an example, after the reform and opening up, it was about the late 1980s to the first 10 years of the 21st century. At that time, a large number of migrant workers entered the city. Because of China’s special system, Chinese urban factories did not need farmers. Therefore, there will be no large-scale peasant influx into the factory. Since the land is already unprofitable, they Where to enter? Construction site. This also catered to the needs of urban construction at the time. This group of people usually returned home only once a year. It was very difficult, but what can be done? In fact, at that time, many people were proud of going to work in the city. When they returned home for the New Year, they brought back a stack of cash, which may not be earned for more than ten years. The film "The World Without Thieves" reflects this situation.

Now, in order to cater to the Internet trend, spectacles must be recreated. The Industrial Revolution China did not catch up. The post-war urbanization China lags behind by 30 to 50 years. Informatization and the Internet wave China cannot fall behind. However, the threshold of this wave is slightly higher. It is impossible for a factory worker or a farm Farmers will be able to program as soon as they sit in the cubicle, so they need a little training. At this time, Chinese universities took the initiative to undertake this matter. Under the guidance of public opinion, the expansion of enrollment has allowed a large number of students to enter the university’s computer-related majors, so a large population has obtained the once very expensive university undergraduate or even postgraduate diplomas, which has laid a solid foundation for supporting the entire wave of Chinese Internet. So far, this group of people is no different from the workers and peasants who went to work in the city, so a large number of people can be poured into this emerging industry every year. So what is the price?

The price is that the barrier to entry into the elite has been lowered, which is a very serious matter.

Speaking of this matter, in fact, I can also expand on two historical events. One is that the Han Dynasty redefined "shi" and "gentleman", and the other is that the Roman emperor Caracalla redefined "Roman citizen." Beijing account, Shanghai account). I don’t have many results, and we still go back to modern times.
Now there are a large number of married people in the IT industry, both of whom are in the IT industry. A larger number of them are in the IT industry. Take me as an example. My wife is not in the IT industry. If I use my circle as a matter of fact, Not fair, because I am in the IT circle, and the probability of people I know is also in this circle, so I take the circle of my wife as an example. She is not an IT person, but the other half of many of her friends are IT people, even Many people heard from older generations and elders are also engaged in IT... IT industry seems to have successfully crushed all other industries.

University diplomas are worthless, and academic qualifications don’t matter, but the situation in the non-IT industry may not change much except for the reduction of national resource allocation. The master of theoretical physics and doctorate are still difficult to graduate, and the master of arts (my wife is) still needs to know According to the classics, I read the classics of history, mathematics, medicine, and even art (excluding movies, performing arts, I mean real music, art). The original threshold is still there, but fewer and fewer people in these majors have applied for the exam. What is elite? Always a very small number of people, with the ability that others can’t reach, and doing very difficult jobs, such as ancient Germanic battle heroes, such as inventors, entrepreneurs, or revolutionary leaders, or scientists, and charities during the great diversion Home, religious people... Now the environment for creating these elites in China is gone. As urbanization continues, the entire population has become a melting pot. There is no distinction between elites and elites in the melting pot. More power. This is how the IT industry succeeds. Now there is a headwind that the real elites have to attend IT training, become programmers or at least enter the industry, otherwise they will not be able to feed themselves. Talents who were once uneducated had to be forced to enter factories and construction sites, but now people who are really literate have to do so. What went wrong?

We have redefined not only elite but also culture. It is precisely because the culture has been redefined that the elite has to be redefined.

What is a cultured person? I think that throughout the ages, there has been freedom of thought and independence of personality. No matter what the problem is, he can put forward his own insights. He doesn’t need to be particularly proficient, but he can guide others to cooperate to accomplish a great thing. When he encounters difficulties, he will take the initiative to face the difficulties and act for the results. , He can draw on the experience of history as a guide for the future. This is called culture. When an industry requires a large number of employees, culture is often redefined. What is culture today?

Nowadays, it has become a new cultural person who understands various programming languages, reads a few idle books in addition to programming, and does not pretend to be work-oriented. You can also watch movies at any time, make appointments with bars, and drive by car. The cultural elite has become a knowledge elite or even a consumption elite. In universities, students will never be taught how to be humans and be a person who is beneficial to everyone. University education has become a technical school for imparting knowledge and skills. Regarding this matter, I think Shandong Lanxiang and Huazhong University of Science and Technology have PK potential. In fact, if Shandong Lanxiang can take some promises to let the students learn for two or three years, and then deliver them to the major office buildings in Shenzhen Nanshan Science and Technology Park and Bantian Huawei Base, the efficiency is much higher than the direct introduction from Wuhan .

I take Huawei as an example. There is a hard threshold for entering Huawei, that is, you must graduate from a prestigious school. Of course, special cases are not excluded, but this is the case with its big culture. Famous schools are 985, 211 and the like. But for those jobs that most people at Huawei do, do they need such a good university? It is estimated that Huawei itself can't tell why the 985 students must be good. In terms of technical ability, Lan Xiang has been training for a few months, and he can make a better screw without any desire. In terms of quality, most of Tsinghua University in North China is already learning not to learn, but what quality do they still have to talk about? Does "strive for self-improvement and be virtuous" still make sense?
...
So ah, don't really catch yourself up with IT, the Internet wave, understand so many programming languages, understand network programming these are too serious, you know everyone knows. Therefore, I support Huawei's layoffs, otherwise what to do with those fresh students. Note that this has become a complete transmission pipeline. Every year, a large number of students enter the computer major from even remote mountain areas, and a large number of students graduate from the computer major each year, which means that there must be a large number of practitioners for these The latecomers made room to leave, although the ending was sad, but this is the reality. Of course, I think the rapid rise of Wuhan and Chengdu in recent years can relieve a lot of pressure for Shenzhen, because graduates who graduate from Wuhan can stay in the local area without having to flock to Shenzhen, and graduates in the west can also be developed rapidly in recent years. Part of Chengdu's traffic closure, but for Beijing, Shanghai, a city with both universities and IT and Internet companies, the pressure is still great.

Is there any way? Enter other industries? I find this difficult. Post a picture, this is forwarded by a friend in my WeChat friends circle, after reading it, I want to write something, so I have this article:
Now that CS is doing the work, many engineering majors, such as mechanics, electronics, automation, and even biomedicine, can learn from you for half a year and come over to grab your job. Most domestic computer companies are project companies, as long as you can use vc, java to compile code, the main advantage lies in the understanding of the industry, so basically staying for three or five years will become an industry expert. As for your algorithm, data structure, and programming efficiency, well, maybe even 30% of BAT positions need to be considered, and one or two people in general companies need to consider it. As for more money just after graduation, you can think that most of the code farmers’ careers will be over by the age of 40. I don’t believe you go to see how Huawei has laid off employees recently. As for the sales and after-sales in the middle of the company, or in the forties, after the age of forty, there are very few. This is not an older and more popular industry (unless you can do the core algorithm), the second is that you may be unemployed after the age of 40, and it is not like a 40-year-old engineering machinery designer who can still find a job (such as my mother-in-law) 50 years old can still be re-employed) occupation. At present, we have not seen the large-scale unemployment of older IT staff. There are several reasons: First, the wave of rapid ITization in society is still at its climax. Once the speed slows down, there will be redundancy. The second is that people who really entered the IT industry on a large scale all entered around 2000. This group of people is now just around the threshold of 40 years old, and will see a large-scale retirement in five years.

In fact, looking back, IT technology is really very simple, much simpler than the technology in other industries. I used to like theoretical physics. I have studied optics for more than a year. Until now, I have nothing to do (this kind of Very few times), I will turn over the book and calculate a few strokes, but I think it is really too difficult, I also learned mechanics, obsessed with Transformers, Transformers in my eyes is not a toy, it is a machine Artwork, I also want to design myself, but I found that I do not have that ability. In fact, friends and enemies around me think that I am a smart enough person, although not a genius, at least my mind is flexible, I have ideas, and I know so. However, in my physics, machinery is discouraged (stop preferring to like , Obsessed), but I found that programming is so simple, so I did not learn to program-because it is too simple, when faced with complex and intractable bugs, several times I always feel that less than half of the physics problem Energy can be done. I am a half-time self-taught college student. I haven’t taught me how to program or trained. I just read books and debug. I found that I can write a string in reverse order... Isn’t it too simple? You find a liberal arts student to try out the polarization of light... In fact, at work, in most cases, the problems you encounter will not be more difficult than the reverse order of the string. Saying what programming requires mathematical skills is all ripping. I don’t deny that masters of programming are also masters of mathematics, but for most practitioners, most people may never write a program that is more complicated than bubble sort in their lifetime, let alone queue up. Basically it is an engineering interface call, as long as you know what is done by calling this interface, and Lan Xiang will teach you enough.

Recently, I encountered a problem and wanted to filter the noise of some discrete data, so I thought of the gradient in calculus. After generalization, I want to use the gradient to judge the flatness of a smooth surface. My idea is to point on the surface Integrate the gradient of the gradient, and also integrate the gradient of the random point,... I asked it in the forum, circle of friends, friends, QQ group, no one ignored me... Most people said that they forgot about me Pretending, instantly made me think that Huawei layoffs 34, 40-year-old, a little late. Then I calmed down and found that I was indeed wrong. Why should I dig myself a hole? Don't I know that programmers have nothing to do with math? If time goes back to the industrial revolution, do I expect a group of factory workers to master the steam engine principle? If I go back to the construction site more than ten years ago, do I expect the migrant workers to tell me about the distribution of the load-bearing beams? Are all extravagant hopes.

During the industrial revolution, if someone clamored that a new era had arrived, then some theorists would say that behind the steam engine was Newton’s Law, Boyle’s Law... Then a peasant or a peasant in trouble entered the factory to add coal to the steam engine. His neighbor will say, the guy is good, this is a high-tech thing. I don’t know if these compliments let the guy continue, and finally fell to the steam engine. Then the boss immediately changed another person to continue adding. coal. Many people have misunderstood the industry and the type of work. I used to listen to my friends saying that I belong to the financial industry. In the end, I was actually selling insurance (I don’t know if the insurance industry is an independent industry)...The same is true for the catering industry. Including chefs, foodies, including dishwashing, delivery, is not it? So ah, programming programmers are just a type of work, and even most of the senior engineers are in vain. These people are the same as the guy who added coal to the steam engine I mentioned earlier, but in modern society, those so-called The senior engineers, experts and the like may be better at using some means than adding in person, but for ordinary programmers, it is really the wave of the Yangtze River that pushes the waves forward, and if you have enough years to go, you should leave. What does that mean? IT and the Internet industry cannot be mixed up. If you want to mix up, be a manager and put on leather shoes before mixing up.

Let me talk about myself first, and then Huawei.
My wife studied Japanese and has a Master of Arts. My major is mechanical engineering. Later, I graduated from college to study how to configure switches for two years and then self-taught computers. I am currently working in an Internet company. As long as my wife is willing, I teach her for half a year. She must be better than me in my industry. However, if I want to learn Japanese, she may not be able to listen to her for two years. This is not to mention the real high-tech industries, biopharmaceuticals, genetic engineering, ballistic missiles, medicine, nuclear power, and Wenzhou leather shoes.

Finally, let's talk about Huawei.

I think Huawei is just a tease.

Let me talk about the wolf sex culture. In fact, I am very disgusted with canines. I often kick and abuse my dogs, but I have never abused cats. (Regardless of the instincts of cannibalism in dogs, eating feces is disgusting, and snatching is despising) I think that the survival efficiency of cooperative wolves is much worse than that of lions. If it is power, tigers can single out half of the wolves. In terms of speed, leopards can kill the fastest wolf, in terms of survival instinct, cats are released, and dogs are released to wait for death. Finally, in terms of economic benefits, hello kitty's global sales spike the sales of any toy dog . So in my opinion, the canine family is defeated by the cat family. If you really want to win, it is better to be a dog than a group of wolves.

Why do many people worship wolves? There are two reasons. Either this person is influenced by the wolf totem, especially the grassland people. It is worth mentioning that the wave is the same as the nomadic people to the farming people, or that this person is illiterate and has been influenced by the first reason. . For this reason, I specially watched the movies and books of "Wolf Totem", which finally made me feel that this was too fake and too biased. I don’t mean to say that the national totem is not good. I thought our ancestors were still bird totems. My hometown still has a huge black bird sculpture... I mean, these so-called totems are mapped to people. Can cause misunderstandings. According to the theory of wolves, then it is bound to die and never retreat, but humans do not have the genes of wolf death, in fact, there are no lions. All cats will almost give in to protect themselves when they know that there is a risk, only Those stupid dogs will know it. You will find that if you meet a cat, almost that cat will run. If it is a small dog, that dog will bark at you, but if you let this cat fight this dog, the dog will not Enemy cat! Cats are solely for their own benefit, but dogs just seem to be very interested. If you meet a lion or a tiger or a leopard alone in the wild, even a bobcat, you basically hang up, but if you foresee a wild wolf, generally an adult man can run it away because of the power of man and the power of wolf Quite well, who can win is courage, but the strength of humans and large cats is not at the same level, courage can only bring death. see it? Maybe people adore this is the canine animal: no matter who you are, I will go all out, either you die or I die. Cats are the opposite: if you are fiercer than me, I will run, otherwise I will kill you. God, this is not a barbaric society, this is a civilized society. Huawei's wolf culture is all about being unconfident and cowardly. This may be related to Ren Zhengfei's personal background. Canines are always on the lookout and never enjoy it. This is the essence, because in strength, canines are completely weak. No matter how they are singled out, they can’t beat even a bobcat lynx or even a cousin traitor of their own ethnic group. Distant relatives such as shepherd dogs, blackbacks, and Tibetan mastiffs also have to give up three points. When a dog is abandoned and then adopted, it will be extremely sensitive, completely distrust the owner, afraid of being abandoned again, but for a cat Words, just a few more meals. If it is a wolf, what it wants to resist is to be adopted as a dog, because once it becomes a dog, it is no longer free, but what can't be changed is its canine nature. This may be the reason why Huawei is not listed. But the wolf was too tired, and still said that, Zhuang Zi asked, "I heard that there are turtles, and they are three thousand years old. Wang Jinying and the Tibetan temple. This turtle would rather die to stay Bone is expensive, but Ning Qi was born to be sloppy?"

In fact, the stupid behavior of wolf sex is ruled out-no one is right against the wolf, and the mediocre is self-disturbing (just like I saw a dog, it also saw me, I walked past it but barked and fooled. ..), Huawei can be more relaxed.
Does it make sense to engage in those 985,211? Although you also know that these people will not support the elderly when they fall, although you also know that these people may not be able to program.

Even if you engage in 985, 211, trouble you to make the interview questions a little harder, get a string in reverse order, you insult people IQ.

Isn’t it a wolf culture? Who is the wolf? Old man. Overtime chanting all night, when (liao third sound) another one to continue. The real wolf culture is completely different from the Qin culture and the Roman Republic. Whether it is Qin or Rome, it is a culture of civilization, not an animal culture, so they can have a good system to maintain military conquest, and no boss is needed at all. In person, no matter whether it is Mallor, Sula, Caesar or Qin Xiaogong, King Zhaoxiang, Bai Qi, Li Si, they have never killed a soldier and a soldier, but the wolf culture is a complete animal culture, a kind of Going all the way to the black culture, if Ren Zhengfei did not go to battle to kill the "Apple and Samsung" overnight, it would be a blasphemy of the wolf culture. If that is the case, I call it the rat culture.

To be honest, Huawei really does not need an employee with a mother who has cancer to continue to work. Taking a step back, Huawei does not need so many excellent employees. Huawei needs to be alone, as long as it is not stupid, stupid or extreme.

Huawei is just an ordinary enterprise, but everyone feels that it is mysterious and has been hooked and brainwashed. In fact, we have more choices. People always like exotic styles. When a once universal value is no longer universal, people are willing to restore it. This is a weakness of human nature.

People generally admire the strong, but are wolves strong? A wolf is a weak person. There is no suspense for an ordinary person to single out a wolf, but why do people adore wolf nature, because wolves can cooperate...wolves can... This is too complicated, it is better to advocate lions. Tigers, just kill rhinos, hippos, crocodiles, and elephants alone, isn't it more fierce? It is indeed more fierce, but the status of other people is gone. Nowadays, people hope that "everyone comes together". We must leave room for ordinary people, even if they lick a bit of blood. This may be the reason for the foundation of Huawei's culture.

Anyway, I still want to say:

The wolf sex culture is the culture of the weak, and wolves are not great animals. In contrast, felines are more successful in terms of strength and cooperation;

Huawei doesn't even need those who really master high-tech skills. Huawei will only turn gold into iron and then be abandoned;

Huawei's technical requirements are much worse than that of ordinary companies, as long as you can encode hello world, they do not understand the Fourier transform and the like;

Huawei laid off staff and laid you down, it was your voluntary, who made you fooled by Huawei at first, and did not disappoint yourself;

The culture of wolf sex is not a symbolic culture. The boss wants to fight the enemy, but does the boss fight the enemy? The boss is just a symbol, but the wolf does not need a symbol.

Huawei layoffs, whether it is true or false, I have to say that this is normal behavior, why?

First, anyone is an elite, anyone is not an elite, they can code, they are all code farmers;
Second, you have to make room for the latecomers, you have to learn something else;
Third, this is a normal phenomenon. It has been used two or three times in 200 years. Get used to it;
Fourth, you must have independent thoughts and not be brainwashed, so you know everything.

At the end of this article, answer a question, what is money? What does more money mean? It just means that you can think of something else after eating and drinking. If you have been thinking of something else, it means that you are not short of money. Go on, just like me.

The latest supplement the next day:
After writing this article yesterday, I had a quarrel with my family and thought that my opinion was too extreme for people to agree with. In fact, my wife's point of view is basically the point of view of most officials, that is, the correct point of view. I have repeatedly emphasized thinking independently, so I don’t care about right or wrong, just expression. Either reason or sensibility, this is just a classification of later people, in fact there is no such distinction.

This supplement is written to clarify some details.

A few days ago, I posted an article "I hope the United States came to shoot "Great Qin Empire"... to show epic shock." My wife's younger brother in Japan said that China does not have the concept of epic, because China has no troubadour.. At first glance, I quite agree that this answer is also very cultural. If we talk about Homer's Trojan War, it will be better and more cultural. I directly replied: There are troubadours in China... Actually, I like this younger brother more. He has always been independent in thinking and is good at analyzing things that seem obvious from different angles. So, this is the matter , I have been thinking for a long time about Chinese troubadours and why China has not left an epic.

But is it meaningful to discuss whether China has epics? I don’t think it makes sense, because the word epic was originally invented by the West. Discussing why there is no epic in China is the same as discussing why there is no Tang poetry in Europe...

I have never thought that if you understand a lot, you will be educated. I have read tens of thousands of books without thinking independently and not educated. Reading is easy, and it is easy to learn the same skills. The difference between people is not as great as expected. As long as it is a course set up in a university, anyone can learn it. The difference is the method of learning. Some people like to read, learn, and learn all the time. Export is a variety of professional terminology, astronomy, geography, and heaven and earth. I don’t agree with this learning method. According to the results, this person may give The impression is that learning five cars, but in fact is a robot.
Mapping to programming, many people think that after reading the Linux kernel source code, the implementation of the protocol stack is proficient, but it is actually the same as those liberal arts students. According to my learning method, when I encounter a mechanism to be implemented in code, I generally write a simple version of the implementation according to my own ideas without looking at the source code, and then go to the existing source code and see See what is different from what I think. If there is a difference, check various materials to understand why the author's ideas are different from mine. I am determined not to directly look at the source code.

What I mean in the text is not a stick to kill all programmers, I am just expressing my dissatisfaction with a reality. This morning, when I was discussing with people, I thought of an excellent analogy. Programmers are actually very similar to chefs. This is just a job, and it is very simple to get started. It is really no difficulty. Lan Xiang has a chef profession. Why can't it replace all universities and return universities to be real?

However, on the other hand, there are super powerful chefs in the chefs, and there will be gourmets in this gourmet business. This is not what Lanxiang Chef School can train. The chef who came out of Lan Xiang can only make ordinary dishes. The first-class dishes in the world can't be made. But now 80% of the dishes are not ordinary dishes?

IT is an industry, and programmers are a profession. However, I don’t think universities should originally aim at exporting practitioners in an industry, nor should they be employment-oriented. Maybe you would say that the pressure is high in order to make money. But do I have to go to college to make money? My point of view is still the same. If you just want to learn to program, instead of going to the computer major in college for 4 years, it is better to go to Lan Xiang, get started quickly, and the effect may be better. Would you object to me saying that training institutions or technical schools do not teach high numbers or mathematical statistics, but do you use those in your usual work? If the basic subjects are just for pretending to prove that they have learned, then it is really better not to learn. I can memorize the chronology of major events in the late Roman Republic. Why should I memorize them? Either to show that I am knowledgeable and literate, or that I simply don’t have the ability to memorize them. I am obviously the latter. Regarding the former, I think that in fact anyone can take a moment to memorize it. Does it make sense? Meaningless! In fact, this is also a problem in the history department of the university.

In any industry, when it matures, the quality of practitioners is really low, which is also inevitable for industrialization. The practitioners are divided into work types, and each type of work is basically monotonous and repetitive. Returning to the Industrial Revolution again, in the 17th and 18th centuries, people in any mechanical field were Daniels, and they all left their own names. In the 19th century, there was no increase in Daniels in this area. The increase, the increase is a large number of workers in the factory, these workers do not need to master any principled things to work. In the 20th century, IT industrialization almost completely replicated the process of industrialization. The number of Daniels in the 1960s and 1970s was similar to the number of Daniels in the 21st century, but there were more and more practitioners. As a worker, is a programmer essentially different from an industrial revolution worker? If it is said that all employees of a type of work need the university to export, I think this is a problem.

What needs to be clarified is that "IT is also simpler than other industries". My wording is not correct here, it should be that the programmer as a job is simpler than many jobs in other industries, and it should not be said that the entire industry. Because IT is currently one of the few industries that requires very large-scale employees, once including manufacturing. In the Chinese cities of the 1980s, bicycle torrents almost appeared in the morning, where did everyone go? It is going to work, and 80% are going to work in the factory. My parents are all workers in the factory. Nowadays, this army of workers is about to be replaced by IT workers. Almost any industry is almost IT-based. If the work in the IT industry is so difficult, it is unreasonable. Even then, someone will come forward to simplify the process. If programming is so difficult, then it must be Someone will make this simple. Now programmers hardly need to be familiar with the underlying principles, do not understand the mechanism of CPU work, and do not understand how memory is allocated, which is also true. Large-scale things must eventually be simplified and automated. However, from the last century to the present, doctors' work has not been simplified, because doctors have never become large-scale practitioners. Let me give another example, when the driver is not large-scale, every driver is a power expert, at least understands his car, and now almost everyone has a driver's license, is that still the case? Isn't the final driver able to go with the push of a button? The things underneath have not been simplified, but the interface is simple. The interface is simplified to allow large-scale people to be proficient in operation. In the same way, CPUs have not become simpler today, but more and more complicated on the contrary, but the work of programmers has become simpler. A large number of simple and easy-to-use frameworks and interfaces have been developed to make things more and more simple. In short, most of them People are doing simple enough things. I remember when I went to my mother’s factory when I was a kid, the workers in the workshop were basically doing very simple things. Generally, there will be one or two public technical experts. If the ordinary workers can’t handle things, the experts will come forward. Experts The number of people is relatively small, because they are generally not needed. The programmer's job is the same, most people do not need to be too complicated to complete the work.

Finally, to clarify the matter of my pet dog, it's called Dudu. I like animals very much, and I didn't kick and abuse Dudu as written in the text. I just made Dudu too personified, which I hate It is the humble kind of dogs, so my heart is more "looking down" toot, sometimes I will scold "get out", stomping my feet to scare it away, but this does not prevent me from liking it.


About the text and comments:

Unexpectedly, an article published on Saturday morning triggered such a fierce comment. In any case, I still want to apologize first, the words are too extreme, to generalize, and despise canines, these are wrong even in the perspective of humanism, wrong is wrong, no explanation, only apology, too grudge Brought too much negative energy, sorry!

After finishing work yesterday, I carefully reviewed all these articles I wrote. The top three comments were actually three spit words: "What's wrong with IT", this article and "Disgusting OpenSSL", which makes People have to reexamine the meaning of blogs.

In fact, after writing so many technical essays, the details may be wrong, the writing may not be intuitive, or it may be too wordy. These are all problems, but no one pointed it out and no one discussed it together, of course. I am still very grateful to many enthusiastic netizens. Afterwards, we also added QQ, WeChat, and a lot of email exchanges. I also got a lot of new ideas from them. Thank you here. But in terms of traffic (of course I know there will be reptiles), most people will not leave any complaints. But for these articles, which are in themselves Tucao, the comments were numerous. In fact, the threshold for vomiting is very low. Someone sent an article, and then attracted a large number of objections or approvals. It seems very fierce and rational. In fact, everyone is at a relatively low level.

I mean that people in Huawei don’t understand the Fourier Transform, which is definitely wrong, but someone immediately objected that Huawei is engaged in communications. It’s a joke not to understand the Fourier Transform. In fact, this is also wrong. Is it true that everyone is engaged in communications? Furthermore, do you have to understand Fourier Transform for communication? In fact, we are all partial. Of course, some words are very pertinent. 985 and 211 are definitely better than general ones, junior colleges, and technical schools. This is absolute, but my mistake is to take extreme examples to explain that 985 and 211 are meaningless. For example, Huawei’s low labor standard seems to mean that 985 and 211 must be engaged in theoretical physics, and colliders must be engaged in genetic engineering, rather than going to a company like Huawei. But opponents also use extreme examples to refute, saying what artificial intelligence, neural networks... this is the means of Tian Ji horse racing, which is to be banned in the contemporary competitive environment, in fact, whether it is a collider, There are only a few who engage in artificial intelligence algorithms, and most of them repeat what they did yesterday. I don’t know which netizen said this sentence is very pertinent.

Ugh...

If there are such large-scale reviewers who can get together on the first day of work on Monday, let’s discuss the Google bbr algorithm, implement a front-end for nftables, or design a new Linux NAT framework that I have always dreamed of. Doesn’t the meaning mean Is it bigger? Anyway, a comment as long as the code is actually no easier than writing the code to read the document, and it also affects the work. In fact, if you don’t have a deep understanding and mastery of network technology, Linux kernel protocol stack, Netfilter framework, VPN technology, and what I call "culture", I dare not send an article like this. As someone said, the difficult ones will not, the participants are not difficult, but the above points or faces are definitely more difficult than writing a string in reverse order, at least for most people.

I regret that many people's enthusiasm for the technology itself has given way to a broader enthusiasm for system evaluation. When dealing with technology, we lack a style of canines. Although canines are at a disadvantage in PK, their advantages are reflected in the study and efforts of individuals or groups, which is to realize their own value, not In order to PK with people. A technology, I learned myself to be happy, I have a sense of accomplishment, nothing more, if you can use it to make some money, it would be even better.

Finally, as for the technology itself, it may be that the forum or know more reflects the interactivity. The blog itself is a place to express your own opinions and then spit everyone together in two groups, which is indeed not suitable for technical discussions. But in any case, the technical essays written with emotions (such as my dissatisfaction with TCP, my dissatisfaction with OpenSSL, my passion for Netfilter, etc.) should be regarded as technical notes, and they are welcome to discuss together. Although these fields are a bit niche and many people are not concerned, even if someone says "what is written is messy and unorganized...", I will be very pleased.

【The lost Internet technology circle】Remember, we are engaged in technology, and we can’t change the system. It’s better not to evaluate the system. We can only improve our technical level. Otherwise, you are kind of saying that you are the kind of person who will retire. If anyone can see the misfortune of the IT people in this article, and the indisputable meaning of the IT people, I am willing to be friends with you.
