I don’t know if notepads are really popular or marketing played a role. Su Wenxiu not only sold all the 5 books, but also brought back 23 orders, which was equivalent to earning more than 500 yuan overnight. Su Wenhai was attracted by his brilliant performance, so he also took out 50 yuan to buy it and helped to make notepads. Du Qiu was reluctant to ask for it. First, it was impossible for kraft paper and inner core paper to always be free. It is very important to have a person who knows how to purchase. Second, this guy is steady and meticulous, quick and good at making things, and very efficient.

Su Wenxiu was very careful. When receiving the order, she asked the customer to choose what words to write on the cover. Du Qiu didn't have to worry about the sentences and focused on writing. He took out all the skills he had practiced for more than 20 years, including Li, Kai, Run, and Cursive, and he wrote casually. He was very happy. The three of them used up all the materials after not long after, so they went out to purchase them separately. When they came back, there was one more person in the room, which was Su Wenhai's girlfriend Wang Huihui.

"Sister Huihui, why are you here? You are not at work today?"

Wang Huihui is a serious college student. After graduating from the School of Economics and Management last year, she went to work in the Yuncheng Municipal Local Taxation Bureau. She has a high education and a good position. She can say that her future is bright. I don’t know how Su Wenhai got it. She took out a list and said, “I’m here to give you money. Our department plans to order 50 notepads. This is a detailed requirement. If you do it well, you can add it.”

Su Wenxiu exclaimed softly and said in surprise: "So many?"

"I went out with the section chief in the morning to do business. When she saw the notepad I used, she liked it very much and decided to purchase a batch on the spot." Wang Huihui picked up a freshly prepared notepad from the table and explained: "We taxpayers often run around. This kind of notebook is light and soft, and the inner core can be replaced at any time as needed. It is very suitable for carrying around and is convenient to use."

While she said, she handed the list to Du Qiu and said, "Our section chief likes your calligraphy very much and wants to write these words on the cover."

Du Qiu took it over and saw it. It turned out to be the eight words "Integrity and dedication to the public, and he could not help but smile and said, "You section chief is really tasteful and has a high level of ideological awareness."

"It's really tasteful." Wang Huihui also smiled, and after laughing, she said, "She felt that the kraft paper was a bit cheaper. She told me several times that it would be great if it was genuine leather. If you have time, it would be better to make a few genuine leather ones, I'll give it to give you a gift and get some orders back."

"Yes, let's find some time to try it."

After Wang Huihui explained the specific details, she took out 50 yuan from her bag and said, "I'm joining the house too, how about it?"

Su Wenhai provided free raw materials for making notepads yesterday, and today he personally participated in the production. It was fair to only pay 50 yuan to join. Now Wang Huihui is here to join the stake. With the premise of a significant increase in orders and profits, he only took 50 yuan to join, which is suspected of taking advantage of a small advantage. Su Wenxiu rolled her eyes secretly to show her dissatisfaction, but Du Qiu took the money with a smile and said, "Sister Huihui is a taxpayer and should understand the company law. It is better to help draw a contract. Everyone signs it. Now it's getting bigger and bigger. It's better to be a little formal, so as not to have disputes in the future."

"It's OK."

Wang Huihui drafted a contract and left after signing it. Su Wenxiu hid in her brother and complained to Du Qiu: "Why do you want her to join? We don't lack those 50 orders, and we took away a quarter of the benefits without doing anything. We are such a rogue!"

Making notepad is just a stopgap solution to the problem of earning living expenses before identity. Du Qiu did not intend to spend too much effort on this and comforted him: "She works in a government department and has a strong demonstration effect. If this order is done well, it is very likely that other units or companies will also come to purchase it. If the cake is bigger, we can share more, so there is no need to be petty."

With 50 orders, it would be inappropriate to make them purely by hand. Su Wenhai moved the workbench in the living room and borrowed a sewing machine from his neighbor's house for Su Wenxiu to use. With the machine, the manufacturing speed has been significantly improved. By 6 o'clock in the evening, he made a total of 37 books, and the efficiency was much higher than yesterday.

In the evening, Su Wenxiu continued to go on duty, while Du Qiu continued to go to the computer room to go on the computer. Tonight was different from yesterday. He did not play for a while before leaving, but stayed in it for four hours in one breath, intending to write a compression software. The so-called "touching and fist" is always the same as other skills. Programming is the same as other skills. If you don't use it for a long time, you will become unfamiliar with it. Moreover, the software and hardware environment in 1995 is not the same as in 2016. Almost all the programs in the laptop cannot be run and need to be transplanted or rewritten. Many software cannot be used to others. They can only do it themselves, prepare for the future and practice it well.

As for why you need to write compression software, one is that this type of software is very useful in an environment with limited storage capacity, and the other is that it is inspired by the administrator named Yuan Tiangang to prepare for the future. In a few months, the epoch-making Windows 95 will be released. In addition to Microsoft, there is another big winner, that is, the compression software Winzip.

As early as the 1991 Windows 3.1 era, Winzip was born. It was originally unknown and did not cause much trouble. However, the situation changed after the release of Windows 95. The simple and easy-to-use graphical interface of Windows 95 greatly reduced the difficulty of using computers, allowing PCs to enter thousands of households, and ordinary people became the main users of computers. On the other hand, the underlying layer of Windows 95 is too closed and unstable, and often collapses.

The failure is not as difficult as DOS in terms of programming and execution efficiency. Therefore, many companies and programmers refuse to develop software for it. Under the contradiction, a huge gap appeared in the market. At this time, Winzip quickly launched a corresponding new version using the development experience accumulated in previous years. Everyone needs to use the compression software. The market is vast, but there is not even a competitor. Naturally, it became a hit and quickly occupied most of the global market and almost became synonymous with compression software.

Winzip was very popular in the late 1990s, but it quickly declined after 2000 because it did not have its own algorithm, but used the Deflate algorithm invented by Philip Katz. Although the Deflate algorithm is free, its intellectual property is in the hands of PKWare. In other words, it does not have its own core technology, and it is in the hands of others. In 2002, due to encryption issues, it stagnated for two years and did not release a new version. As a result, it was taken advantage of by another compression software WinRAR and replaced it.

Du Qiu planned to port the open source software 7-ZIP commonly used in 2016 to 1995. 7-ZIP uses the LZMA algorithm that appeared in 2001. The compression rate and compression speed are better than Winzip. The disadvantage is that it consumes more hardware resources during compression, which doesn't matter in 2016. Anyway, the computer's performance is too surplus, but it needs to be carefully considered in 1995. You must know that the computer memory in the computer room is only 1M, while his laptop has 16G memory, not to mention the CPU performance gap...

In addition to hardware, the software development environment is also very different. Laptops use 64-bit Windows 10, while computers in the computer room contain 16-bit MS-DOS 6.0, and programming tools are only TurboC/C++3.0 compiler launched by Borland in 1991. This compiler is very classic and is standard in many schools and companies in the 1990s, but it is already outdated for Du Qiu. To use an analogy, if Microsoft launched the latest version of VisualC++ compiler in 2015 is equivalent to the M16 automatic rifle, then TurboC/C++3.0 is equivalent to the bronze sword of the Warring States Period. The bronze sword can certainly kill enemies, but its efficiency is definitely not comparable to that of the automatic rifle.

Even the programming language itself has changed. The C language used the C90 standard formulated in 1990 in 1995, and the C11 standard formulated in 2016. Many new features that have long been used to cannot be supported by the old compiler, and frequent errors are reported. It takes a process to re-adapt. Therefore, Du Qiu wrote very slowly and only spent dozens of lines of code in one night.

When he got off the computer, he inserted the floppy disk into the floppy drive, copied the code, and hacked into the campus network server. He wanted to see if there was anything new, but he couldn't help but feel a little disappointed. If 2016 was used as a reference point, the level of Yunda Computer Department in 1995 was still in infancy, and both theoretical research and technical level were relatively backward. Among the many papers downloaded yesterday, except for a few foreign products, the rest were all computer applications in certain specific fields, such as mine safety monitoring, corporate financial management, etc., and there was almost no general software or Internet content.

The next few days were calm, making notebooks during the day and writing codes at night. Before he knew it, Du Qiu spent the first week after the time travel. On the morning of January 8, he came to Su Wenxiu's dormitory as usual. After entering the door, he saw one of the brothers and sisters standing at the window in a daze, and the other sitting on the sofa cutting kraft paper, each of whom was silent, and the atmosphere was a little solemn, so he asked, "What's wrong?"

"Our business was stolen." Su Wenhai turned around and picked up a notepad and threw it over, and said angrily: "It's shameless to copy our entire line!"

The shape and material of the notepad are exactly the same as what they did, except that the text on the cover was not written by Du Qiu. After looking at it, he smiled slightly and said, "This word is more sophisticated than what I wrote, with a rigorous structure, vigorous and vigorous, and has a deep understanding of the essence of Liu Gongquan and is of good level."

"It's not bad! I know that I can take advantage of it everywhere and have the ability to do it..."

"Brother, please say less." Su Wenxiu dissuaded Su Wenhai's complaints, and then explained to Du Qiu with apologies: "Last night, my father asked my brother to go home with me for dinner. During the meal, he said that they also had to make notepads in the factory, and the price was only half of ours, 10 yuan a book."

Du Qiu has been with his brother and sister day and night these days, and has long known about their life experience. Su Wenhai was originally an employee of the printing factory in Yuncheng University. Last summer, he was arrested and detained by the police for fifteen days because he was drunk and had a fight with someone. His father was the director of the printing factory. He was upright and could not rub sand in his eyes. He was furious afterwards. Not only did he fire him from the factory, but he also drove him out of the house. Su Wenhai had to live in his sister's dormitory and relied on repairing electrical appliances. He was extremely frustrated, so the gap between the father and son was very deep.

"The printing factory has not been in good condition in recent years. It can only print some papers or journals, and it cannot make money. It depends entirely on the school subsidies to pay basic salary. Now the Chinese New Year is coming. My father saw that our notepads are selling well, so he planned to make some to subsidize the employees in the factory for the family." Su Wenxiu was very sensible and first excused his father, then frowned and said distressedly: "There are dozens of employees in the printing factory, and if it is the family, he can make hundreds of books a day, and it is so cheap that we can't compete with them."

Du Qiu knew from the beginning that the notepad, which had no technical content, was easily copied, but he didn't expect it to come so quickly, and his competitor was the father of a partner. However, he didn't take this small business seriously, so he couldn't be angry. He persuaded him: "Brother Hai, since your father asked you to go home for dinner, it means he has forgiven you. What's the point of having to worry about with his father? If the money is gone, you can earn it from other places. If the family affection is gone, you will never be found."

"I don't want him to forgive!" Su Wenhai muttered in a low voice, saying, "The winter vacation will take about ten days to go. The old man wants to make a fuck before the holiday. This morning, he will sell goods in all the stores in the school for a big sale. In this case, what should we do with the 50 orders we took yesterday?"

A notepad is sold for 20 yuan, and the cost is less than 4 yuan, and the profit is very high. However, New Year's Eve in 1995 was January 30. The school will have a holiday around January 18. The sales period is only a short ten days. Therefore, none of the three of them are devoted to making notepads. They are all busy at night. Du Qiu goes to write codes, Su Wenxiu goes on duty, and Su Wenhai either repairs electrical appliances or goes shopping with Wang Huihui, so his production capacity is limited and he can only make about 50 to 60 notepads a day.

When Du Qiu saw Su Wenxiu doing hunger marketing without a teacher, she took out the method of Xiaomi hyping up F codes, allowing her to only receive 30 orders on the spot every day and secretly send 20 order places to friends or colleagues, asking these people to resell and sell them everywhere, creating a popular atmosphere, thus maintaining their reputation and hope to continue selling hot next semester. Now the printing factory has launched low-priced products on a large scale, which has completely broken the rules of the game. Not only is there no chance next semester, but those students who place orders yesterday will definitely choose to return them.

"Or why we'll cut it to 10 yuan?"

"If the price is reduced, there will be an avalanche effect. The students who bought a few days ago will also come to return the goods, so it will be in vain." Du Qiu shook his head and rejected the proposal, saying: "All the orders yesterday were cancelled, and the deposit was returned, declaring that we stopped production and did not do it. The previous ones were out of print, so as to stabilize the confidence of those people ahead."

Su Wenxiu felt lost when she heard this. She put down the scissors in her hand and said in a somewhat awkward tone: "What a pity, there are still many materials that are useless."

When a product faces competition, it either fights a price war to pursue market share or goes to high-end to pursue maximum profit. Du Qiu thought for a while and said, "Do you still remember what Sister Huihui said a few days ago? Their section chief thinks that kraft paper is too priceless and wants genuine leather. College students have limited consumption capacity, so they give their business on campus to your father. Let's do genuine leather, and specialize in making money from outside the school. There are millions of people outside the school, and their consumption capacity is strong, and the market is very large."
