It seems that in 1995, the USB1.0 standard had not been formulated, let alone USB drives. Floppy disks are the most commonly used rewritable mobile storage media, and there are still a few pictures...

Du Qiu picked up a floppy disk with interest and looked at it, asking, "Is there any gaps in these or not?"

"It's okay to buy it. It costs 3 yuan per piece. Take it back and format it yourself and it will be blank."

Su Wenxiu whispered from behind: "There is this in the education supermarket, one is two dollars, and it is never used."

"You get what you pay for. I'm better than the ones in the education supermarket." The administrator was very smart. He guessed what Su Wenxiu said, and the salesperson of the Shican Lotus said: "These are floppy disks purchased by the computer department teacher internally. IBM imported from the United States. IBM is the leader in the world's computer industry. The floppy disks were invented by their family and have the best quality. The ones in the education supermarket are made in Taiwan and broke in a few times. Besides, I also give away games here, all of which are genuine. If you really want to buy them, each one will cost dozens of dollars."

I was speechless when I was doing this pirated business...

After registering, Su Wenxiu left. Du Qiu bought two floppy disks, put on shoe covers, and walked into the computer room with air conditioning and carpeted. In the 1990s, the computer was expensive, rare and prone to problems. He was treated as a princess, preventing cold and heat, moisture and dust, and making the computer room the same as the presidential suite in a five-star hotel.

Although Yuncheng University is a key university directly under the Ministry of Education, it ranks relatively low and does not get much resources. Yuncheng's local economic level is limited and it does not provide much financial support. Therefore, the school's hardware conditions are very average. The computers in the computer room are commonly known as 386, that is, using 80386 as a CPU-compatible machine. 80386 is a chip released by Intel in 1985, which is two generations behind the Pentium chip released in 1993. It can be said that it has been out of date.

1M memory, 40M hard disk, 33MHz CPU, 14-inch spherical display, and a roller-type mechanical mouse...

What a shabby configuration, so nostalgic feeling...

Lin Dawei is a guy who likes to pursue new trends. He is proud of his money. In 1993, he bought a miscellaneous 386 computer on the grounds of practicing typing. After practicing for a few days, he left it at home to eat dust. Later, he was used as a game console by Du Qiu. He was able to use DOS commands to open various games before he graduated in kindergarten. He also used it to learn programming in elementary school. It was not until 2000 that he was eliminated and replaced with a new one. Later, when he was in college, he often used DOS to install DOS to reminisce. Therefore, he is not unfamiliar with the computer in 1995, and it is no problem to use it.

After a few minutes, Du Qiu found that although he could not access the Internet, he could access the campus LAN of Yunda University. There were more than 50 computers online on the network. He walked on it for a while and found that all of them were computers in the computer room. Like his, the hard drive was empty and there was nothing fun, so he decided to go to the server to check it out.

In 1995, there were very few people in China who knew computers and had not experienced the baptism of the Internet wave. The network security awareness was almost zero. Du Qiu cracked the server administrator password without much effort. The server used the Solaris workstation of SUN. It was much better than the computer in the computer room. There were a lot of things in the hard drive, mostly stored by the computer teacher in the computer department. After browsing it with interest, he downloaded all the papers and documents in it and put them in the floppy disk I just bought, and prepared to print it out and read it carefully to understand the specific situation of the current domestic computer industry.

The USB drive in 2016 was based on G units, and there was no need to worry about capacity issues for storing text-like things. However, the floppy disk in 1995 was only 1.44M, and it was soon unable to be installed. Du Qiu had to go to the administrator to buy two more floppy disks. During the transaction, he leaned over and looked at the computer screen. He originally wanted to talk about the strategy of "The Three Kingdoms" and get familiar with the administrator to continue to come to the computer in the future. But he found that the screen was not a game, but a C/C++ compilation interface.

"Brother, what program are you writing?"

"I'm working on a graduation project." The administrator handed the change to Du Qiu, and said in a calm tone but proud expression: "I plan to write a compression software."

In 1995, the Internet speed was slow and the hard drive was small. It was very promising to use compression software. Du Qiu suddenly became interested. He lay on the service desk and looked at a few lines of code and asked: "What algorithm do you use, LZ77, LZ78, or LZW?"

LZ77, LZ78 and LZW are the three most commonly used basic algorithms in the field of data compression. It is difficult to avoid them by writing compression software. When the administrator saw his professional question, he restrained his pride and said, "I use the Deflate algorithm."

When Du Qiu heard this, he immediately understood that he was writing a compression program of zip. The Deflate algorithm is a variant of LZ77. It was invented and distributed for free by legendary programmer Philip Katz. All files compressed using this algorithm are extended with ".zip". The most famous one is Winzip, which once dominated the compression software market in the Windows 95 and Windows 98 eras.

"DOS-based or Windows-based?"

"Windows, I think the graphics operation interface of Windows is the future development trend. Now computer prices are down quickly and are getting cheaper. It is too difficult to use DOS with pure command line and is not suitable for ordinary people."

It seems that in 1995, the domestic people were not as slow as they imagined. Su Wenhai could predict the future popularity of computers through prices, and this guy also predicted...

"Based on Windows, it seems that there is a Winzip that uses the Deflate algorithm."

"I know, but Winzip is not suitable for Chinese usage habits. I plan to optimize it and write a pure Chinese..."

Du Qiu only heard a few words and knew what this guy was going to do. He planned to copy Winzip, put a Chinese shell, and add some irrelevant fancy functions to treat it as his graduation design work. This is exactly the same as some scientific research institutions taking back foreign open source software, changing icons, changing them to the Chinese interface, and then claiming to have independent intellectual property rights to cheat funds.

The administrator was very good at observing his expression. Seeing that Du Qiu's expression was a little playful, he stopped explaining awkwardly and asked, "Are you also from the computer department? I have never seen you before, a junior or a graduate student?"

"I'm not from the computer department." Du Qiu vaguely removed his identity and introduced himself: "My name is Du Qiu, where are you?"

"My name is Yuan Tiangang, from Computer Class 2."

Hearing this name, Du Qiu couldn't help laughing. Yuan Tiangang knew what he was laughing at, and grabbed his already messy hair and explained: "It's not the Yuan Tiangang in "The Queen of the Generation", but the steel of steel. I'm not a Taoist priest, and I can't read the picture."

"It doesn't matter if you can't see the appearance, it's good if you can see the money."

Du Qiu put the remaining papers on the floppy disk and left. He stayed in the computer room for less than 40 minutes. He went down to the fourth floor and said hello and was about to go home to study the documents. Su Wenxiu found an excuse to follow him out of the reading room and asked with a smile: "Guess how many notepads I have sold?"

"All 5 were sold?"

Su Wenxiu stretched out her right hand, flipped back and forth in front of him twice, then made a V-shaped gesture with her index finger and middle finger, and said proudly: "These five were sold, and they received 7 orders, a total of 12."

20 yuan was only enough to have a takeaway meal in 2016, but in 1995 it was equivalent to two or three days of living expenses for an ordinary college student. Du Qiu was a technical resident before traveling through time. He never went through a business. When setting the price, he was completely confused and did not think about it carefully. He was also a little weak. Unexpectedly, he sold 12 in less than 40 minutes. Therefore, he was very surprised and asked: "How did you sell it?"

"I put five books on the service desk to display them. If someone asks me, I will say that this is a consigned work by a calligrapher. Each one is unique. There is no spot stock. You can only book it. If you want, you will pay a deposit of 5 yuan first, and then someone will pay the money."

Oh! Girl, you have a lot of business talent. You actually learned to play monkeys without a teacher. Oh no, it’s hunger marketing...
