Chapter 959 I'm blind

"Hello, my name is Nan Yi, Daqiang, are you a computer student?"

"Hello, Nan... Master, I am from the Department of Sociology of Marx University." Liu Daqiang said calmly.

"Oh, is computers taught by themselves?"

"Yes."

“Can you program it?”

“I can do C and Basic.”

"Since you know programming, I'll give you a big and small job. I'm going to install a software on the computer in the store. No matter what software the customer installed on the computer or what files he stored, after the computer restarts, the computer will return to its previous pure state. There is nothing else to do except for two games.

Of course, I will need to install other software on my computer in the future, so the software I want to compile needs to be added repeatedly and deleted files that need to be protected. I said so, can you understand?"

"Master Nan, this software is not difficult to write. I will definitely write it well with one month." Liu Daqiang agreed.

"Oh?" Nan Yi asked: "Tell me your ideas, such as how to ensure that the software you wrote will not be deleted?"

"Well……"

Nan Yi's question stopped Liu Daqiang, and he couldn't say anything at all.

"It's okay, think carefully. Let's talk after you think it through." Nan Yi patted Liu Daqiang's arm and comforted him.

One question made Nan Yi figure out where Liu Daqiang's programming level was not much higher, which was even more unreliable than his half-bucket water person. Liu Daqiang was definitely not good enough to write the "restore software" he wanted.

Nan Yi skipped over Liu Daqiang and pushed Huang Saner into the store, leaving Liu Daqiang to regret his mistakes there.

After walking around the store, Nanyi saw that each computer had a floppy drive, so he said to Huang Saner: "Tonight, don't let anyone come in after nine o'clock. At ten o'clock, I'll come here to disassemble the floppy drive. I don't need to have every computer. Just leave five of them. I'll sell the floppy drive in Zhongguancun."

Huang Saner pointed to the floppy disk opening on the computer host, "Master Nan, are you talking about dismantling the things here?"

"Um."

"No, I see that many students are carrying that kind of disk to plug in here. If you dismantle the things, they can't use them."

Nan Yi pondered for a while, "Then leave ten units. Those with floppy disks are easy to mess around, and computers are easy to break. You just said that the business is good, and I plan to wait and see. If the business has been good, buy a few more cheap computers to form a diskless workstation to reduce costs."

"What does the diskless workstation mean?"

"Haha, this thing is so professional. Not everyone in Zhongguancun who works on computers understands it, so don't ask."

"Master Nan, you are not a computer student, how do you understand?"

"Edison, Einstein has to call me a genius when he comes to life. Why can't I understand?"

"Master Nan, you can go to the overpass to sell your mouth."

"Your uncle, go and reconcile."

Nan Yi could only brag in front of Huang Saner. If he really understood, he would not dare to brag. He could tell the story of Wupan Workstation, but he only stayed at understanding the principles and let him do it. He could only catch the blind.

By the way, Feilong Internet Cafe has already achieved a turnover of 175,000 yuan. It cost 240,000 yuan to buy a computer, a table, chair, bench, and a store to dress up, and it cost 18,000 yuan. The house is a state-owned unit, with a rent of 800 yuan a month and a year of 9,600 yuan. By the calculation, if the turnover can continue to maintain the status quo, the cost will be recovered in less than a month.

But it should not be easy. Nanyikan has only three customers left in the store, and the other machines are already empty. When the students are on vacation, the business will definitely fall a lot. Huang Saner just said something right.

After closing the account book, Nan Yi said to Huang Saner: "I will send you 140,000 tomorrow, and you will count half of your shares."

"become."

Huang Saner answered very simply and didn't worry about the thousands more Nan Yi gave.

Nan Yi explained to Huang Saner what Tang Laidi and Wu Xiaoxiong were going to come, then flew directly and returned to his mother-in-law to wait for dinner.

That night, Nan Yi took out ten floppy drives from the computer. The next day, he got Zhongguancun and couldn't get back twenty network cards. In anger, he still paid for the exchange and spent money to buy a network cable and a 10M Ethernet switch. He spent 5,000 yuan to buy a junk computer from a shop selling second-hand computers.

Computers these days are expensive, and a piece of garbage costs half a thousand yuan.

Waiting again until the evening, Nanyi connected the computers of Feilong Internet Cafe into the LAN. Internet cafes that can access the Internet abroad have appeared. Two years ago, the game companies began to focus on LAN online games. I believe that online games with good playability will appear in the future. Nanyi formed LAN to wait for online games, and the other to install billing software.

It is too troublesome to take a notebook to record the time of on-boarding and off-boarding. Moreover, with billing software, you can directly transition from first spending and then paying to paying the deposit first. This can avoid the embarrassment of customers not having enough time out, and can also allow customers to devote themselves to entertainment without having to keep their hearts hanging, and their eyes should be aimed at the time in the lower right corner from time to time.

In his previous life, Nan Yi met a primary school student who was taking breakfast money online in an Internet cafe. He only had one or two dollars in his pocket. When playing games, one eye had to stare at the time and the other eye had to pay attention to the Internet cafe gate from time to time, for fear of timeouts and fear that the adults he was familiar with suddenly appeared.

Nan Yi is probably both exciting and nervous when he is a primary school student, and that feeling is definitely not good.

Moreover, things like escaping orders will happen sooner or later. Using billing software can also reduce the expected losses. In addition, Nanyi also has the idea of ​​selling a few billing software to make a little more profitable.

As Feilong Internet Cafe becomes popular, those who follow the trend will definitely appear. Nan Yi will tell Huang Saner that if someone comes to learn from the door, don’t hide your own private matters and teach others all the tricks - you must buy a Huayi brand computer, build a LAN, and use Yizai billing software.

If no one comes to ask, Nanyi will publish soft articles in the computer newspaper and actively spread knowledge. Some people come to learn from other places, and they also provide free service to receive the store from the train station. When they come here, they will be served with good tea and cigarettes.

Whether it is a computer, switch or software, as long as someone buys it, Nanyi can share the benefits.

Compared with restore software, the difficulty of developing billing software is worth mentioning. Nan Yi can write it out without three days after he gets started, but he doesn't plan to do it himself.

On the 12th day of the twelfth lunar month, taking advantage of the fact that the store had no business, I pulled a socket to the door of the store, plugged in an induction cooker, put ten kilograms of lamb scorpions, and brought five kilograms of lamb rolls, two bags of mother-good dumplings, and five people in the store were simmering mutton together and ate dumplings.

After picking up a piece of sheep scorpion into his bowl, Nan Yi waved his chopsticks and said, "Don't be restrained, let go and eat it. Lai Di, eat it in big mouthfuls, look at you're thin."

Nan Yi has not seen nutritional deficiency for several years, but unexpectedly, he saw it again in Tang Laidi. Although he is not as thin as Liu Zhen, whether it is his complexion, skin or hands, he can see that he was hungry when he was a child, and never had any good food when he grew up.

Born in a poor family that favors boys over girls, he is also the fourth child. You can imagine how much hardship Tang Laidi suffered when she was admitted to Beijing. In depth, she reasoned that at least one of her three sisters was very great. Without the sacrifice of her sister, Tang Laidi would not have the opportunity to study.

Nan Yi had already figured out what kind of inhuman life Tang Xdi lived in the buyer (in-law's house). He was really fucked. If you can't afford to raise his parents, don't have to have a child. If you can't afford to raise them, you can't even think of marrying a wife for them. At that time, I guess he will still have a few daughters, especially Tang Laidi, the most promising one.

After a while, Nan Yi saw that Liu Daqiang and Wu Xiaoxiong had already let go. Tang Laidi was still a little restrained, so he advised him again. After the second invitation, Tang Laidi finally let go and eat.

After all, the eating speed became faster. After a while, the scorpion was harvested, the mutton rolls were cleaned, and when the dumplings floated in the country, Nan Yi spoke again, "Daqiang, you heard that your accent is from northern Jiangsu?"

"I'm from Suyu."

"Oh, a good place. Su Yu has produced many celebrities. He studied at Marx University and chose sociology. Are you going to work in politics, right?"

Liu Daqiang was stunned for a while and said, "I thought so before the college entrance examination. My high school class teacher once told us that if anyone among you can become mayors, he can lead more people to live a good life.

Because of the head teacher's words, I filled out my first choice in Malaysia University. When choosing a major, I thought that sociology is a little helpful for being an official in the future, so I chose this major. Now my idea has changed. I want to be a businessman more than being an official."

"Why?"

Liu Daqiang's face became dark, and hesitated for a while before saying, "I started too late than my classmates."

Seeing Liu Daqiang's face and hearing his answer a little against his will and obscurely, Nan Yi quickly changed the topic, "Why are you learning programming? Is it to make money?"

"Yes, not right. When I was a sophomore, I heard from my senior brother that sociology is not easy to find a job, so it is best to study a second major. I think the future prospects of computer science should be very good, so I learned programming."

Nan Yi nodded, then looked at Tang Laidi and Wu Xiaoxiong, "Where are you two, why do you learn computers?"

Wu Xiaoxiong said: "High school teachers say that computers are a popular high-tech major, and the unit will rush to ask for it after graduation."

"Laidi, where are you?"

"It was also the teacher who helped me choose. She told me that the country often sees news in the newspaper that the country attaches importance to computer education."

Most of the parents of students in mountain villages in poor areas are not very educated and do not understand the outside world. Don’t expect them to make constructive suggestions for their children to choose majors. At most, they can say something good about majors, or the former college students in the countryside have returned home in glory, and then they want to copy other people’s footprints to their children.

Han Shao has a powerful relative in his family who can provide advice. In their world, the easiest to find, the most reliable, and the most suitable person to inquire is the child's teacher. Therefore, behind the rural college students who jumped out of the countryside in the 1980s and 1990s, there was most of them a good teacher, and this good teacher played a major role in the life path of students.

"Haha, you three are good students, otherwise your teacher would suggest you take the normal school entrance exam."

In 1989, the university started to pay tuition fees, not much, only a symbolic 200 yuan per academic year, but with living expenses and tuition fees, it would cost about 600 yuan a year. This is an astronomical figure for families in mountainous areas. If anyone has a college student, the family will definitely be famine, and it is not uncommon to borrow all over the village.

Therefore, the normal university that is still free has become the first choice for many poor students.

After laughing, Nan Yi continued, "You three can be considered to be computer learning. The day before yesterday, I set up a LAN in the store and prepared a billing software. You also saw that there was an additional second-hand computer in the store. I plan to use this computer as a host to control other computers.

The billing software is ready to implement three functions, one is billing and timing. For example, a customer comes and gives a deposit of 50 yuan, enters the computer number and amount into the software, and after calculation, it is calculated that you can play for 200 minutes, and then starts counting down immediately.

The second function is the reminder and automatic shutdown function. When the guest plays until the 195th minute, a pop-up window will appear on the top of the screen on the computer he is playing. The reminder will be 5 minutes away. Please renew it in time.

If the customer does not renew the fee, then when the time reaches 200 minutes, a pop-up window will appear again, and the computer will automatically close after one minute.

The third function is the lock screen function. If the guest does not register at the counter, he will directly turn on the computer and see a protective screen that requires entering a password. The guest must pay a deposit at the counter to play.

Of course, there are many college students here, and there are computer experts in it, so it is not difficult to crack a lock screen password. This is also the reason why I have to remove some floppy drives. Without floppy drives, you cannot plug in floppy drives. It can block some mediocre hands and make them give up the idea of ​​cracking.

But this is not enough. I hope that as soon as the computer is turned on, it will send a verification string to the host, and send different strings in different states. Moreover, this string cannot be a simple 1 or 0. It is necessary to automatically generate random characters and add the current time to obfuscate it. Then, the Md5 algorithm is used for encryption. Once the sent string is incorrect, the host will alarm.

All three of you can figure it out. Can you write this software? If you can write it, I will give this software to you three. Now you think about it and make sure you can write it. Let’s talk about the reward.”

After Nan Yi finished speaking, he took out a dumpling from the pot and said to Huang Saner while eating: "Is it very popular to play bowling now?"

"It's so popular. Now people like to drill into bowling alleys, shoot women and discuss business in bowling alleys. Master Nan, I looked a little jealous. I was thinking a few days ago if I opened a house."

“Is there anyone reliable?”

Huang Saner's face turned right and said, "Glasses and melon are still following me."

"Spread it out, go to the bowling alley for a month, how many people go to play every day, who go to play, how much flow can you do in a day, and how many days you check the frame on average, you have to figure out whether this business can be done, and you will know when the investigation is clear."

"Okay, I'll arrange someone tomorrow."

"Well, the two of them are still mingling with glasses?"

"Help me run errands, I will give them each of them a thousand eight hundred a month."

"Can't you save money?"

"If you can't save it, you can make money hard."

Nan Yi smashed his mouth, "I still have to do some business, and I'm not too young anymore. I'll start to buy some property and get married."
