In 1986, the Beijing Institute of Computer Application Technology cooperated with a German university to build a Chinese academic network, and in 1987 sent China's first e-mail, in 1989, the State Planning Commission used the World Bank loan to start the China National Computer and Network Facilities Demonstration Network Project, which is referred to as NCFC. The NCFC passed the national acceptance in 1992 and was connected to the Internet through satellite in April 1994, marking that China has officially become a country with full-featured inter services.

Five months later, that is, in September 1994, the Ministry of Posts and Telecommunications of China and the U.S. Department of Commerce signed an agreement on international Internet access services, the State Administration of Telecommunications will cooperate with the third largest telecommunications operator in the United States through satellites, open two 64k special lines in Beijing and Pujiang, and provide Internet access services to the public, this project was completed in January 1995, and the specific day of completion is not available, after completion, Beijing and Pujiang have a total of 32 dial-up ports, a port can support about 10-29 users, remove the spare port, and can support about 500 Internet users at the same timeAlthough it is very shabby, it is considered to be the beginning of the commercialization and popularization of the Internet in China, and it is of great historical significance.

The above is the history of China's Internet development that Du Qiu learned before crossing, Yuncheng is a central city, and it is not a short journey from Beijing and Pujiang, even if the two 64K special lines were opened on January 1, 1995, it is impossible to pave the cable overnight, so he can only pin his hopes on Yunda, hoping that Yunda has joined the NCFC project, but now it seems that he thinks too much.

Windows 95 has not yet been released, Linux is still a toy, and the Java language is still being tested......

Netscape hasn't gone public yet, Yahoo hasn't incorporated a company, and Google doesn't even have a shadow......

If he can access the Internet, Du Qiu has countless opportunities to get rich, but now he has no identity and no funds, so he can only nest in Cloud City, and he can't show his skills, like a golden dragon trapped in the shallows, he took out his wallet with no interest, drew ten yuan, handed it over with Su Wenxiu's work card, and said, "I'll be on the plane for 1 hour." ”

After renting a house and making a big purchase yesterday, there were more than 900 yuan left from the 2,000 yuan extorted from my father, all stuffed in my wallet, which is nothing outside the school, but it is a little eye-catching in the school, after all, in 1995, the tuition fee of college students was only a few hundred yuan a year, and the living expenses were even smaller, the administrator looked at the wallet, pursed his dry lips, and asked, "Do you want anything else?"

"What's that?"

"The computer in the computer room is for studying, and there are no games on the hard drive. The administrator bent down and took out a cardboard box full of floppy disks from under the service desk, and said: "This has "Monopoly", "Tetris", "Knights of the Burning Dragon", "Dune", and the "Three Kingdoms 3" I just played, you can rent it to you, a game is five cents, the time is not limited, and it will be returned to me when you get off the machine." ”

This guy is very business-minded......

It seems that in 1995, the standards had not yet been formulated, let alone the U disk, the floppy disk was the most commonly used rewritable removable storage medium, and there were really a few copies......

Du Qiu picked up a floppy disk with interest, looked at it, and asked, "Are these for sale, are there any blank ones?"

"If you want to buy it, it's okay to buy it, 3 yuan a piece, take it back and format it yourself, and it's blank. ”

Su Wenxiu reminded in a whisper in the back: "There is this in the education supermarket, two yuan a piece, and it has not been used." ”

"You get what you pay for, and I'm better than the one in the education supermarket. The administrator is very shrewd, guessed what Su Wenxiu said, and said with a lotus smile: "These are floppy disks purchased internally by the teachers of the computer department, IBM original genuine products imported from the United States, IBM is the leader of the world's computer industry, the floppy disk is invented by their family, the best quality, those in the education supermarket are made in Taiwan, and they will break after a few uses, and I also send games here, all of which are genuine, and each one will be dozens better if you really want to buy it." ”

I am speechless about this piracy 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 carpets, in the 90s, computers were expensive, rare and prone to problems, and they were served as princesses, cold-proof, heat-proof, moisture-proof and dust-proof, and the computer room was the same as the presidential suite of a five-star hotel.

Although Yuncheng University is a key university directly under the Ministry of Education, it is ranked relatively low, and it does not get too many resources, and the local economic level of Yuncheng is limited, and it does not provide much financial support, so the hardware conditions of the school are very general, and the computers in the computer room are commonly known as 386, that is, 80386 is used as a CPU compatible machine, 80386 is a chip released by Intel in 1985, two generations behind the Pentium chip released in 1993, which can be said to have long been outdated.

1M RAM, 40M HDD, 33MHz CPU, 14-inch spherical monitor, scroll-wheel mechanical mouse......

What a shabby configuration, so nostalgic feeling......

Lin Dawei is a guy who likes to chase the new trend, as soon as he has money, he has to be scared, in 1993 to practice typing as the reason to buy a miscellaneous 386 computer, practice a few days on the home to eat ashes, and later Du Qiu as a game console, kindergarten has not graduated when you can be proficient in using dos commands to open a variety of games, elementary school programming is also used to get started, until 2000 to eliminate the new one, and later when I was in college, I often used a virtual machine to install dos to nostalgia, so I am no stranger to the computer in 1995, and it is not a problem to use it at all。

After tossing for a few minutes, Du Qiu found that although he couldn't access the Internet, he could go to the LAN of Yunda University, and there were more than 50 computers online in the network.

In 1995, there are very few people who understand computers in China, and they have not experienced the baptism of the Internet wave, the awareness of network security is almost equal to zero, Du Qiu did not spend much effort to crack the administrator password of the server, the server is the Solaris workstation of Sun company, the configuration is much better than the computer in the computer room, there are a lot of things in the hard disk, most of them are stored by the teacher of the computer department, he browsed it with great interest, downloaded all the papers and documents inside, put it into the floppy disk he just bought, and prepared to print it out and take a closer look, to understand the specific situation of the current domestic computer industry.

The 2016 U disk is based on g, and there is no need to worry about the capacity of small things to store text, but the floppy disk in 1995 is only 1.44M, and it will soon be unable to fit, so Du Qiu had to go to the administrator to buy two more floppy disks. At the time of trading, he leaned over and looked at the computer screen, originally wanted to talk a few words about the strategy of "Three Kingdoms", and was familiar with the administrator, so that he could continue to come to the machine in the future, but found that the screen was not a game, but a C/C++ compilation interface.

"Dude, what program are you writing here?"

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

In 1995, the network speed was slow, the hard disk was small, and it was a promising thing to engage in compression software, Du Qiu suddenly became interested, he lay on the service desk and read a few lines of code, and asked: "Which 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, and it is difficult to avoid them when writing compression software. ”

When Du Qiu heard this, he immediately understood that he was writing a zip-like compression program, the deflate algorithm is a variant of LZ77, invented by the legendary programmer Philip Katz and distributed for free, all files compressed by this algorithm are with the ".zip" extension, the most famous of which is Winzip, which once dominated the compression software market in the Windows95 and Windows98 eras.

"DOS-based or Windows-based?"

"Windows, I think the graphical operation interface of Windows is the future development trend, now the price of computers is falling quickly, getting cheaper and cheaper, pure command line DOS is too difficult to use, not suitable for ordinary people. ”

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

"Based on Windows, it seems that there is a WinZip that also uses the Delate 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 listened to a few words, he knew what this guy was going to do, he was ready to copycat winzip, set a Chinese shell, and then add some irrelevant fancy functions, as his graduation design work, which is the same as some scientific research institutions take back foreign open source software, change the icon, replace it with a Chinese interface, and then advertise that they have independent intellectual property rights to cheat funds.

The administrator was very good at observing words, and saw that Du Qiu's expression was a little playful, so he stopped explaining abruptly and asked, "You are also from the computer department? I haven't seen you before, junior or graduate student?"

"I'm not from the computer science department. Du Qiu vaguely revealed his identity and introduced himself: "My name is Du Qiu, what about you?"

"My name is Yuan Tiangang, and I am from the second class of computers. ”

Hearing this name, Du Qiu couldn't help laughing, Yuan Tiangang knew what he was laughing at, grabbed his already messy hair, and explained: "It's not the Yuan Tiangang in "The Empress of the Generation", it's the steel of steel, I'm not a Taoist, and I don't know how to look." ”

"It doesn't matter if you don't look at it, just look at the money. ”

Du Qiu put the remaining papers into the floppy disk and left, only staying in the computer room for less than 40 minutes, he went down to the fourth floor Su Wenxiu to say hello, ready 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: "You guess I sold a few notepads?"

"All 5 sold?"

Su Wenxiu stretched out his right hand, flipped it back and forth twice in front of him, and then made a V-shaped gesture with his index finger and middle finger, and said proudly: "All 5 of them were sold, and 7 orders were received, a total of 12." ”

20 yuan in 2016 is only enough to eat a takeaway, but in 1995 it is equivalent to the living expenses of an ordinary college student for two or three days, Du Qiu was a technical nerd before the crossing, never went through business, the pricing was completely blind, and did not carefully consider, he was also a little weak, I didn't expect to sell 12 in less than 40 minutes, so I was very surprised, and asked: "How did you sell it?"

"I put five notebooks on the desk to display, if someone comes to ask, I say this is a calligrapher consignment work, each is unique, there is no stock, you can only book, if you want to pay a deposit of 5 yuan, and then someone will pay. ”

Yo girl, you have a lot of business talent, and you actually learned to play monkey without a teacher, oh no, it's hunger marketing......

Not only that, but she also played a game of concept marketing, not saying that this is a notepad, but saying that this is a calligraphy work, which suddenly increased the forced grid by n times, the so-called art is priceless, and no matter how expensive the price is, it can be said that in the past......
