Sunday, June 3, 2018, sunny.

Today's weather is extremely hot, less than ten o'clock in the morning, the highest temperature outside has reached 30 °C, on the balcony, Chen Xu rolled up his sleeves while applying computer thermal grease, while wiping sweat with his elbows.

I don't know how long this dual-core integrated display old computer has been useless, and a thick layer of dust has accumulated in the chassis, and it takes a lot of effort to clean the ash.

Then the system crashed, the mechanical hard disk was bad, the CPU thermal grease solidified, and he, a work-study student, was willing to come to the door to repair it, send it to the computer store, and people gave her 100% a word - upgrade!

After reinstalling the fan, plugging in the memory module, and connecting the power supply, the fan "dropped" and rotated, and the 22-inch AOC monitor was connected, and the BIOS settings were already entered.

Take out the Huawei 2S data cable and connect it to the computer, open the backup system in the mobile phone, choose to start from the mobile phone, and the computer will automatically install the system after restarting.

Ten minutes later, the system was installed.

After restarting again, it took two minutes for the computer to slowly enter the desktop like an old cow pulling a cart.

Accustomed to the start-up speed of a few seconds or more than ten seconds, this speed made Chen Xu and the others' bladders ache faintly.

But I finally saw the classic blue sky and white cloud pattern.

Set the screen resolution, open the 360 security guard, and want to prohibit the unnecessary boot startup items that come with the system.

But what he never expected was that 360 was stuck there and didn't move.

Dead chickens again!

Press Ctrl+4 twice more to go straight to the blue screen.

.

At this moment, a middle-aged woman in the kitchen came over with a plate of cut watermelon, looked at the blue screen monitor and smiled: "Come, Xiao Chen, eat a piece of watermelon and get it again." ”

A high-achieving student of Zhonghai University of Science and Technology, and he still learns computers, and he hasn't done a good job of a broken computer for a long time, which makes Chen Xu a little faceless, touching his nose and laughing dryly: "That...... Aunt Wang, this computer ......"

Aunt Wang took over the conversation and said with a smile: "Auntie knows that the computer has indeed been around for some years, and she wants my eldest grandson to come over occasionally to make trouble, but his parents don't let him play with his mobile phone."

If you really can't fix it, forget it. ”

"Uh...... It should work. Chen Xu didn't dare to say too much, in case the hardware was damaged and couldn't be repaired, it would be too much of a slap in the face.

didn't eat watermelon, Chen Xu squatted down and checked it in the chassis, and soon found that it was really a capacitor on the motherboard that burst the pulp.

Chen Xu was a little depressed, it was simple to replace the capacitor, but the problem was that he didn't have an electric soldering pen, and there was no capacitor in the toolkit, so he had to remove the motherboard and take it back to repair.

"Auntie, this capacitor is broken......" Chen Xu pointed to the yellow electrolyte on the top of the capacitor and explained to Aunt Wang, and the damp fingers of his right hand had touched the electrolyte as he spoke.

In the next second, Chen Xu only felt a strong electric current transmitted from the tips of his fingers to his arm, and then through his elbow to the right half of his body, and it was all numb in an instant.

Chen Xu, who was squatting there, was knocked to the ground by the "poof" of electricity, and the bursting capacitor on the motherboard also emitted black smoke with the "zizi".

Aunt Wang, who was standing next to her, was startled, and immediately turned off the electric plug board switch on the ground, and exclaimed, "Xiao Chen, how are you ......?"

Aunt Wang didn't see it, and at the same time as she turned off the power switch on the computer, the mobile phone screen plugged in the case as if it had tripped, and the picture of the car used as a screensaver gradually disappeared, replaced by a green seed the size of a soybean grain.

"Xiao Chen, you speak......"

"Don't scare Auntie......"

……

Seven or eight seconds later, Chen Xu, who was lying on the balcony floor tiles on his side, slowly turned over, lay flat on the ground, opened his eyes and looked at the fiery red sun in the sky with a confused expression, thinking in his mind, who am I?

Soon he remembered that his name was Chen Xu, 22 years old this year, a sophomore at Zhonghai University of Technology nicknamed the "Home Appliance Maintenance Station".

Then more memories came flooding back.

His hometown is in Anling City in northern Jiangsu, which is a plain area, neither backing nor rich in natural resources, although the business card of external propaganda often has something to look at the Hanguo Smecta, and the foot basin chicken across the sea, in fact, the two have a chicken feather relationship.

What makes Chen Xu even more depressed is that he takes out the map of the rabbit country and takes a look at it, and you will find that those coastal cities TM are all rich, but Anling City, which has an ultra-long coastline of more than 500 kilometers, has not developed.

Because there is no deep-water port, it is all tidal flats.

As a migrant worker in the city, his father worked as a stevedore in Anling City, to put it bluntly, as a laborer, and his mother worked as a vegetable worker in the hotel, earning a salary on Weibo, barely enough for his three children to go to school.

He has an older sister and a younger sister, and his sister is now also studying in the first year of graduate school at China Overseas Normal University, and his sister will take the college entrance examination in a few days.

Not to mention the magic capital of Zhonghai, let's just say that the per capita income of his hometown Anling City last year has exceeded 40,000 yuan, and the annual income of his parents together is about 50,000 or 60,000 yuan, and the family has been living a tight life.

The only thing to be thankful for is that the whole family is in good health. It is a blessing for the poor not to be sick.

Of course, poverty itself is a disease.

"Hey, 120 ......"

Just when Chen Xu was thinking about the mess in his mind, the sound of Aunt Wang calling for an ambulance came from his ears.

"Aunt Wang, I...... I'm fine. Chen Xu struggled to get up from the ground, shook his head and said, "No...... No need to call an ambulance. ”

Aunt Wang, who was about to report her address, saw that Chen Xu had actually gotten up, and asked with a scared look on her mobile phone: "How are you? Do you feel unwell? No, Auntie will take you to the hospital for a check-up." ”

"It's really okay...... Chen Xu moved his shoulders, raised the fingers of his right hand and looked at it, a small white dot was electrocuted from his fingertips, and there was a black circle around it, as if it had been blown up by a firecracker.

"The capacitor leaked and was electrified. Saying that, Chen Xu moved his fingers, except for a little numbness, there were no other uncomfortable symptoms.

When Aunt Wang saw it, she finally breathed a sigh of relief, put down her mobile phone and said, "This computer seems to be really unusable." Forget it, go back and go buy a new one. ”

Chen Xu was half electrocuted, and he didn't have the energy to say anything at this time, nodded and unplugged the data cable on the USB interface and put it in his pocket along with the Warwick 2S, put it aside after installing the chassis cover, packed up the tools and left.

Before going out, Aunt Wang forced 50 yuan of manual fees to him, and told him to go to the hospital to have a look, and she would reimburse the expenses when he returned.

The computer was not repaired, and it startled people, Chen Xu was embarrassed to say anything more, and fled in a hurry after answering a few sounds.

……

Out of the Dongyuan community, walk along the road to the west, and soon came to the overpass, the east of the bridge is the commercial street of Binhe District.

It may be because of Sunday, the bus stop under the bridge is full of people, hugging each other and rubbing shoulders, but the overpass behind is like mercury pouring on the ground, constantly "flowing" down with the crowd, the bus here has just picked up a batch, and the crowd of people pouring down on the bridge quickly fills the vacant parts.

Chen Xu glanced twice and continued to walk forward, less than a kilometer in front of him was the Binhe District Polytechnic University Branch.

After walking less than 200 meters, the phone rang in my pocket, and I took it out to see that it was my former roommate Zhu Carrier, and asked with a smile after connecting: "Boss Zhu, what are the instructions?"

Zhu carrier's family is a native of Huzhou, the family is to open a mechanical processing factory, the annual output value is said to reach hundreds of millions of scale, the standard rich second generation, freshman lived in a semester dormitory, sophomore and school girlfriend moved out to live and fly. Of course, there are still beds left for inspection.

Zhu Cheng on the other end of the phone yelled and said, "Hey Mr. Chen, I don't know what's going on on my computer, it's always dropped, you come over and help me see what's going on." ”

Because the people in the dormitory looked for Chen Xu whenever there was a problem with the computer, everyone called him "Teacher Chen" after a long time.

"What's the wrong order?"

"I'll see...... 651。 ”

"It's a terminal that can't be connected, is there no money?"

"No way, I'm on a monthly basis, you better come and help me take a look. ”

"Then you wait for me, I'll be there shortly. ”

"How long will it take?"

"Ten minutes. After hanging up the phone, Chen Xu was depressed.

At the beginning, he didn't know what major to choose, and then he heard on the Internet that learning computer science is very flexible and money-loving, such as PS and 3Dmax, and he can be an artist in the future, doing house design and graphic design;

Able to AE, non-editors can make videos, advertise large-scale corporate activities, etc.;

Then you can become a network engineer if you learn network development, you can become a software engineer if you learn software, and you can also rely on technology to do freelance work on the Internet, in short, the income is very good.

In the end, he chose the Department of Computer Science.

But when you peel off the coat that exudes the temptation of money, you know that TM is all an illusion, and the real situation is that every previous life who learns computer science is an angel with broken wings.

People learn a language only to learn one, they have to learn a lot, C alone has C, C++, C#, J's is also divided into JAVA, J2EE Jxxx, and they are all different, another one can not be compiled, because the computer is a big pen, less colon it will not know.

They all speak French and German, and the numbers are difficult to read, so you can find a random algorithm book, which is as thick as Nima Kangxi's dictionary.

There are also various "stacked tree diagrams", which are divided into generative trees, minimum spanning trees, directed trees, non-trivial directed trees, binary trees, trivial binary trees, balanced binary trees, complete binary trees, and completely regular binary trees...... Just hearing the name makes me dizzy.

In addition, the operating system and Linux server need to memorize various commands, and the database needs to learn a SQL language, MySql is not the same as orcle's SQL.

By the way, I also have to learn computer English, those are professional terms, he often failed English in his third year of high school, and it cost him his life to memorize a word, and now it's even bigger, and others are reviewing the code there before every exam, and he memorizes words sadly.

What's more, the trick is that many non-computer majors like Zhu Carrier think that as long as he understands everything related to computers, retouching, installing systems, installing computers, repairing computers, repairing printers, and even looking for him if there is a problem with an Excel sheet.

If you say no, people will think that you know but refuse to help, that kind of contempt...... Day!

For more than a year, he has also been forced out, installing computers, installing systems, repairing computers, repairing printers, and the price of computer peripherals.

Not to mention, I basically don't have to worry about living expenses now. -_-||。

……

While laughing at himself in his heart, Chen Xu had already come to the south gate of the Zizhu Garden Community rented by Zhu Chengyun......
