One Planet for Everyone! Building Science and Technology Civilization at the Beginning

"Di", the computer did not enter the operating system startup steps after the motherboard self-test, but restarted again.

Zhou Lei heard the sound of the computer restarting in the kitchen. He probed out and glanced at the computer screen placed in the corner of the living room. He didn't find it stuck, so he went back to tangle whether to eat small wontons or big wontons at night, which is related to the national economy and people's livelihood.

At this time, the computer did not enter the Windows startup interface, and immediately began to refresh the screen of the data stream. A large number of garbled characters were like waterfalls, and strange characters were all over the screen. Finally, the characters on the screen were connected into a line. White strips.

Zhou Lei was holding a big bowl of small wontons with a few drops of sesame oil and shrimp skin in it. When he came out of the kitchen, the computer had entered the windows 20 interface.

For the old guys, XP is completely finished, and win20 is the last position to persist. To be honest, MS's recent operating system is more anti-human, so I don't want to upgrade. For a server with some parts over 5 years old, win20 is the most suitable system.

Zhou Lei entered a password of a super middle school two, "Il0vexia0jingjing", because Xiao Jingjing was his first love girlfriend. However, the family was married early, and the baby was in primary school. Zhou Lei was still thinking about it, but it was estimated that he was not missing this person, but that period of youth.

While eating small wontons, Zhou Lei opened the resource manager, ready to browse the contents on the mobile hard disk.

A little drive letter will pop out a dialog box, you need to format the hard disk.

Sure enough, there will be no pie in the sky, this hard disk is bad. Zhou Lei tried to format the disk, but the program kept going wrong. Come on, just pulled it out and threw it in the drawer.

Zhou Lei has hamster disease and likes to hoard some things very much. Like these useless hard drives and broken cables, he will throw them in the box, and he will clean up some of them until they can't fit any more.

Because I didn't want to be angry with some online disk service providers, I built a home NAS, Black Qunhui, and made a RAID5 with 4 hard drives. It's full of messy novels, technical tutorials, etc. He has downloaded resource sites such as verycd over and over again, and even reluctantly deleted a large number of documentary videos before finally putting all the data into the NAS.

There was even a second year in middle school, where he had collected a large number of martial arts secrets and prepared to practice peerless martial arts. After hitting himself more than a dozen times on the head with a children's sponge nunchaku he bought online, he was so angry that he packed the secret book and never read it again.

So he probably doesn't know how many things are hidden in his NAS.

So he is such a middle-aged greasy uncle full of childlike innocence, half a dead fat house.

After eating the frozen little wontons that are always the same flavor, Zhou Lei suddenly felt that he was a bit of a failure. Although I am happier than some of my classmates and friends who have to pay off their mortgages, I always feel that I have been doing nothing in the past few years, and I am busy with trivial things. After leaving this company, I found that all my skills have no place to use.

It is impossible to go to Party A, it is impossible in this life, there is no way.

So take advantage of the time when a large amount of money arrives, prepare to watch a few American TV series at home, read some books that have not been time to read, and if you still have time, learn some new technologies.

Opened the website of the American drama and saw that there were more new ones coming out. Zhou Lei was quite happy. It happened that the previous ones were almost the same.

Open the download tool, copy the address link, and click Download. Originally, it was a good thing. According to the 500M telecommunication fiber optic at home, it is estimated that it can be downloaded in a few minutes.

WTF, what's going on? A few K of traffic, isn't this back decades ago?

There is a habitual paralysis of the broadband in the community. Recently, the number of telecom paralysis is increasing.

Zhou Lei opened Guangmao's management page and found that the speed is very fast. The uplink and downlink speeds are full, but there is no traffic on his computer. And I didn't find any other unknown devices connecting in. Besides, who doesn't have broadband, as for stealing traffic?

Try restarting, drinking more hot water is a valuable experience in life, so the first reaction is to restart the light cat.

Sure enough, after restarting and reconnecting the computer, the speed of downloading software suddenly increased. After a few seconds, the speed is gone again. Zhou Lei scratched his head, this was beyond the scope of his own technology. You said to create a server or something, we can still do it, but repairing the cat is really not good.

Come on, Zhou Lei is about to hang up, and the download software on the computer can't always occupy the traffic. It should be able to be downloaded by tomorrow morning.

Zhou Lei found that his smart TV and mentally handicapped stereo were also finished. Without traffic, he could not watch TV or listen to music. Then take a look at the stock on the NAS, and refresh several old movies a few times.

The TV remote control was almost broken, and the film actually disappeared.

When it was over, Zhou Lei suddenly woke up, and it was estimated that he had been hacked.

He quickly went back to the computer and carefully checked the inventory of his NAS. My God, the teachers are all gone, the funny movies of Xingzai I like are gone, the rest are sci-fi and the full set of Resident Evil is still there, Miss Alice finally didn't lose it.

Could it be that this big hacker is a fan of sci-fi movies, and Zhou Lei tried to talk to the hacker for the sake of it. It is said that you can use text software to enter text to communicate, which is a rumor handed down from ancient times. He opened notepad++ and typed "Hello!" on it.

Oh my gosh, what did I see.

Also under "Hello"

A "Hello" appeared, and it was indeed hacked.

Zhou Lei quickly typed in the software, "Please spare your life and return the film to me."

"Please spare your life and return the film to me." A repeated sentence appeared below.

"Please don't joke, big brother, this is my collection for many years."

"Please don't joke, big brother, this is my collection for many years." There is a repeated sentence below.

...

After coming and going, what words Zhou Lei typed, what words would be copied below. Zhou Lei was thinking, I guess this eldest brother is a fool.

Zhou Lei thought he couldn't communicate anymore, so he quickly took a look at what was left.

Fortunately, I lost some video files, almost 2 T. If you lose it, you will lose it. Even after some teachers retire, they basically can't find the video. It's a pity, but most of the things are still there. I actually saw something. The hacker brother helped to organize some of the information that I didn't have time to organize very neatly.

A hacker with obsessive-compulsive disorder doesn't see any harm in him other than deleting videos. Zhou Lei was relieved a lot, but he couldn't play with you, "Boss, farewell."

Zhou Lei was disconnected from the Internet for a while all night, and then connected to see if the hacker had left. It was almost 12 o'clock after the toss, Zhou Lei had given up, let him go, let him play enough and he should be able to leave.

Turn on the light cat and router, and even turn on the computer, and go to sleep directly.

I woke up at 8:00 in the morning and everything was normal. The huge traffic disappeared, and the new American dramas were downloaded. There are several new works of the latest popular teachers in NAS. After a look, the taste is OK. There is also a new Spider-Man film that was released in the United States yesterday. It is estimated that it is a gun version. Click on it and take a look.

Zhou Lei couldn't help but shout, OMG, this is a 4K-level film, this hacker is too good. Well, I saved almost 100 yuan, and I don't have to go to the cinema. We also despise those who watch pirated copies. It’s just that other people have good intentions and want to know them, but they don’t want to spread them. If they catch them, they will go to jail.

At this time, the short message on the mobile phone rang, the bank reminded, and the transaction was carried out!

The transaction amount is 302,821.22 yuan, and the available balance is 309,982.82 yuan.

Almost all of Zhou Lei's money is placed in online financial management. Although there are profits and losses, it is generally better than depositing in a bank. I took a look some time ago, and I have almost 500,000 in funds. With the newly added funds, it will take several years, so I don't need to look for a job for a while.

Suddenly the mobile phone mailbox program has a push, you have a new mail.

Zhou Lei opened the mail software on the computer and downloaded the new mail. Generally, the current mail software has a certain amount of spam filtering, and Zhou Lei looked at the email and said "new technology for smart cars". He usually plays with this kind of MCU when he has nothing to do, from 16-bit to 32-bit, so it is estimated that it is the data push sent by those forums that he often goes to.

Zhou Lei opened the email, the text was blank, and there was a 5M attachment.

After downloading and saving, unzip it, there are some programs and a drawing inside.

Yo, this is not bad, Zhou Lei found out that it is the circuit board of a smart car. This kind of mentally retarded robot has been popular for more than ten years, but it has always been a toy, and most of the time it will be reduced to a toy for pet dogs and cats. But almost every tutorial that plays embedded will have a smart car.

Zhou Lei found that he had almost all the components on the circuit board, so he might as well try it out.

Directly open AltiumDesigner to import drawings, automatically route, generate circuit boards, and then make appropriate manual adjustments to produce boards. The breadboard really doesn't want to play, it's easy to connect, and a lot of poor contact problems can make people completely crazy.

Zhou Lei pulled out a copper clad laminate from the warehouse box, as well as potions, and everything to play. The printer was moved out, the drawings were printed on the film, and then transferred to the copper clad laminate, and then the unnecessary parts were washed with medicinal water.

Played from morning to afternoon, in the process of waiting for the corrosion of the copper clad laminate. Zhou Lei has played the simulator with Proteus and Keil, and found that there is no problem with the program.

The next step is to punch the copper clad laminate and apply flux. Some of them use conventional long-leg components, and some are patch-type. After all, it is not easy to find suitable specifications in a pile of components, and it is not required to be beautiful, as long as it can be used.

Then I got a STM32 minimal system, fixed it with a hot glue stick, and connected the wiring.

I found a few more motor driver boards and stepper motors, and used wheels that were removed from the toy.

Reluctantly set up the frame before going to bed, Zhou Lei connected the wire for burning the program to the car, and after guiding the program inside, he couldn't hold back and went to sleep.
