Li Laoshi is a reporter from Yuncheng Evening News. A few months ago, he heard about good people and good things from friends who were a policeman. He thought it was a good news topic, so he ran to the person involved for interviewing. He ended up feeling disappointed, losing face, and making a very unhappy fuss.

Unexpectedly, more than a month later, the sister of the person involved suddenly called to inquire about the price of advertising in the Yuncheng Evening News.

In 1995, when the national system reform was in the era of great national system, all walks of life were transforming into a market economy. In addition to running news, reporters also had advertising sponsorship business. Li Laoshi had failed to meet the standards for two consecutive months, and if they failed to meet the standards for another month, they would be criticized. When they were in a state of turmoil, a big pie fell from the sky. They were overjoyed and immediately put aside their old grudges and helped them run errands actively and enthusiastically. They successfully obtained the full version of the large advertising contract. Not only did they complete the task, but they also earned a small bonus.

Afterwards, he was grateful and wrote a series of articles in succession, reporting on Yunda's posters, rendering amazing sales, praising the product design, and complimenting the brand's image. Each article was written with great effort and perfection. It was soon appreciated by Du Chunhua, general manager of the Thinker Cultural Products Company, and became the company's official pen. He often received some small gifts or pen payments, and his life was much more abundant than before.

On April 30, Li Laoshi took a step off and was instructing his younger brother and sister to do his homework at home. Suddenly, he received a message from Du Chunhua, asking him to go to the company, and then was hit by a bigger pie. Manager Du's younger brother, the hero who was brave at the beginning, was actually the founder and boss of Snapdragon Software Company.

Foreigners are pursuing products, and their employees earn more than 10,000 yuan a month. The boss of a high-tech company that has been on the front page of the People's Daily is actually a native of Yuncheng, which is a big news in itself!

This is not enough. There is even bigger news, that is, this boss is actually moving the company from the prosperous capital to the remote Yuncheng!!!

"Reporter Li, can this press release be on the headlines of your newspaper tomorrow afternoon?"

"Yes, absolutely no problem!"

Li Laoshi forgot to take Run's money, and took a taxi that he usually couldn't bear to take. He ran back to the report agency excitedly and pressed the press release on the editor-in-chief's desk. At that time, the editor-in-chief seemed to swallow a raw egg, which made him wake up in a dream at night.

The report squeezed out the very important but well-known notification news, "After Labor Day, the whole country officially implemented a five-day work system a day after Labor Day", and successfully made it to the front page of Yuncheng Evening News, and soon spread throughout Yuncheng, from government officials to street vendors. Everyone knew that Yuncheng had an awesome person and opened an awesome company. Li Laoshi himself was also very excited. When he got off work in the evening, he specially brought a newspaper home, and pressed it under the pillow seriously, because this was the first time his name was printed on the front page headline.

Early the next morning, Li Laoshi got up and was about to go to Sanjiang University for an interview in advance to report in detail about Du Qiu's technical speech. However, as soon as he got on the bus, he received a message from the editor-in-chief and asked him to report back to the agency as soon as possible, because the municipal government sent someone to inquire about Snapdragon software.

Li Laoshi had to return to the newspaper and told the secretary from the municipal government everything he knew. Then he went to Sanjiang University with the secretary. After arriving, he found that Du Qiu was unnatural and unique. He linked his speeches with Thinker’Notebook’s new products, which were perfectly matched and complemented each other, creating an excellent publicity effect. He was very newsworthy. He immediately thought about it and wrote three articles in one morning.

However, these three articles are just appetizers, and the real main course is the afternoon speech. Unfortunately, Li Laoshi is a liberal arts student. Not to mention programming, he can't even start the computer. He can't understand a line of code. Standing in the crowd in the back row of the lecture hall, like listening to a book in heaven, clouds and mist, unable to grasp the key points, and he doesn't know how to write a report.

When Du Qiu held a textbook and blasted all kinds of mistakes and missed them, causing tsunami-like discussions in the lecture hall, he immediately felt that he had found a breakthrough point, so he grabbed a student beside him and asked, "Student, who wrote this book?"

"A professor at Qingcheng University is quite famous."

Qingcheng University is one of the best universities in China. Will professors of this school publish a book with more than 200 mistakes?

If there are hundreds of typos in a novel, it will definitely be an unqualified product. Du Qiu is holding a textbook, and it is a textbook used in college. How could there be more than 200 mistakes?

Li Laoshi originally thought it was written by an unknown author, so there were so many mistakes. Unexpectedly, the author was actually a famous professor at Qingcheng University. He was shocked and asked in disbelief: "There are so many mistakes in this book?"

"I don't know if there are more than 200 people, but I only know that there are some minor mistakes in it." The student said casually with a rational, objective and neutral attitude: "This is just an introductory textbook, and it is inevitable that there are some mistakes."

The friends around him couldn't listen and retorted: "The more you get the first-class textbook, the more rigorous you should be. Otherwise, you will form wrong ideas or develop wrong habits, and it will be difficult to correct them in the future. I have long said that this book is garbage, and you even treat it as a treasure!"

"I didn't use it as a treasure. I mean, as an introductory textbook, the requirements don't need to be too high."

"Just kidding! The requirements for introductory textbooks are not too high? If you have the ability, you can speak a standard Mandarin to me, right? Isn't it because you didn't learn the pinyin well when you were a child, and you were led by the teacher. Now you can't change it even if you want to."

"Pinyin is pinyin, programming is programming. I dare to despise my accent and come out to fight..."

Mr. Li Lao thought this was a good analogy, so he secretly remembered it, and then asked other students around him. He found that some agreed with Du Qiu's point of view. Some people disagreed with it, thought Du Qiu's words were exaggerated, and some didn't care. He thought Du Qiu was making a big fuss.

After asking the students' opinions, Li Laoshi went to ask the opinions of the two colleagues next to him. The reporter from the Provincial Daily felt that this was a literati and no big deal. The reporter from the Municipal Daily said lightly with a smile that insight into the world: "It's just a sensationalist. The author of this book is very famous and has a large circulation. As long as you find some small mistakes from it, you can prove that your level is better."

After hearing this, Li Laoshi realized something. He felt that Du Qiu was indeed sensational, but not proving his high level, but advertising for Snapdragon Software Company. Judging from the scenes in the lecture hall, these remarks are extremely controversial and will definitely trigger big discussions in the industry after they are circulated, and the discussion will inevitably boost the popularity and popularity of Snapdragon Software.

Du Qiu does have the intention of advertising, but that is just a casual one, not the main reason. The main reason is that this book is indeed of poor quality and has many errors and omissions. However, since it was published in 1991, it has been promoted everywhere by administrative means and has become a general textbook for computer grade examinations and colleges. In more than 20 years, tens of millions of volumes have been released, which has misleading children and has endless poisons. In 2014, enthusiastic netizens made an incomplete errata statistics, and found nearly 500 errors and omissions. You should know that it was the fourth edition after many revisions!

It's all the fourth edition, and there are so many mistakes. Is it the first edition used in 1995? How many errors should be there?

A textbook with more than 300 pages actually has nearly 500 mistakes. How many students who use it to teach can become qualified programmers?

If programming is compared to basketball, a good textbook should teach people how to dribble, pass and shoot in standard postures, and cultivate good basic skills and team awareness. In this way, no matter which team you play, you can quickly integrate into it and eventually grow into a professional basketball player. This textbook not only dribble, pass and shoot postures are not standard, but also teaches people how to take advantage of tricks, how to attack people, and how to cheat fouls. It is useless except for dealing with exams. After learning, you can't cooperate with anyone, and eventually you can only become a ball gangster who bullies children on the street basketball court...

When Du Qiu first learned C language, he also used this textbook to get started with it and learned a lot of messy but meaningless things. Afterwards, under the guidance of his senior brother Chen Yuanqi, he took a lot of effort to correct his wrong thinking and habits. He was deeply hurt. Now that he has traveled through time, he naturally has to denounce it so that later generations can skip this pit.

In 2016, there were many excellent posts and high-quality textbooks on the Internet to refer to. Compared with the two, students could quickly discover the mistakes and omissions of this textbook. However, in 1995, apart from the photocopy version of the books, students had almost no reference materials. They were easily misled by this textbook. Whether it is right or wrong, they were regarded as the standard, and they believed it without doubt, causing extremely bad effects.

If Snapdragon software develops smoothly, it will definitely recruit a large number of fresh graduates in China as programmers in the future. If every student needs to be retrained before he can take the job, it will be time-consuming and labor-intensive. It will be time-consuming and labor-intensive. Let the students actively discover the mistakes in it. Wouldn't it be better to correct them yourself, save time, effort and worry-free.

"Don't argue for now. Practice is the only criterion for testing truth. Is the way of thinking taught in this book correct or not? You can tell if you have a good programming habit." Du Qiu knocked on the microphone twice, then switched to a PPT picture, and said: "The windows operating system has a text editor called notepad, which is the notepad program that people often use to open txt files. Its functions are very weak. When I returned from New York a few days ago, I was very bored on the plane and planned to write an enhanced notepad program, but it has not been completed yet."

Du Qiu switched to a document with software function planning and introduced: "In addition to basic text editing, it can also be used as an editor for computer programs, supporting code highlighting, code folding, and expansion plug-ins..."

After introducing seven or eight functions, he switched to a document full of codes and said, "This is part of the program source code I completed. It has been placed in the computer room server of Sanjiang University. Interested students can download or print it out. Everyone can work together to complete it. Students from other schools do not need to worry. After the speech is over, I will entrust all teachers to bring the source code back and also place it on the server of the computer room of the school."

"In addition to the code of this text editor." Du Qiu took out another CD and signaled: "There are source codes for excellent open source software such as FreeBSD, Linux, vim and Emacs. I will also entrust all teachers to take them back and put them on the school server for your reference."

This is a female student who raised her hands high. Seeing that Du Qiu nodded and allowed her, she stood up and said, "Teacher Du, wouldn't it be very chaotic if everyone is changing the source code randomly?"

"Open source software does not mean free and casual. Every excellent open source software has a very strict management method. For knowledge about this, after the speech, you can learn about it from the booklets collected by Teacher Cai. I will briefly introduce it here..."

After Du Qiuyan briefly introduced several different types of code management modes, he pointed to the code on the screen and said: "You can submit the code you wrote to the server in the computer room. I will check it once a week and integrate the qualified code into the main program. If you write it well enough, I will see it."

There was something in the words and meaning, and there was a buzzing noise in the lecture hall.
Chapter completed!
