Chen Xu left Volkswagen's fourth son store with his driver's license that exuded the scent of ink.

The fourth son shop stipulates that the driver's license internship period is less than three months, and no test drive of a new car is allowed. Although he also practiced with Yang Haidong's "little wife", no matter what he said, the salesman just didn't agree.

After leaving the Volkswagen store, I went to the Honda Four Sons store, and after entering, I looked around the inside and out of the CRV, and then asked the opinions of the Sui people.

The Sui had their mouths slightly open, and their handsome faces were filled with "I don't understand", "Don't ask me", "I don't know anything".

Then, in Chen Xu's encouraging eyes, he walked to the side of the car and looked around, and said, "It's quite big."

Chen Xu: "......"

Chen Xu asked the salesman if he could test drive it just after he got his driver's license.

The salesman said yes.

Chen Xu was overjoyed and said, "I just got it today, okay?"

The 30-year-old male salesman said with a bitter face: "Brother, don't tease me~"

Chen Xu understood.

After leaving the Honda store, I was going to visit the Mazda store.

But when I think about it, I can't test drive it, and I can't tell that I'm ugly just by looking at it.

"Forget it, don't look at it~" Seeing that the sun was about to set, the two of them simply went home.

Taking a taxi back to the downstairs of Dehong Building, Chen Xu thought that he hadn't come to the company for more than a week, so he got out of the car and went up to have a look.

The company is still the same, with a few green plants added, and the rest has not changed.

Seeing Chen Xu coming, Wang Wei and Wu Zhiqiang were both very happy.

Wang Wei excitedly introduced: "Now there are four books on the shelves, each of which has a daily sales of more than 2,000 yuan, and according to the five-fifty divide, there are 30,000 yuan a month." The main reason is that the update is more violent, 20,000 words a day, and it is difficult to think of high sales. ”

Chen Xu leaned over and looked at the webpage, and the comment area of several books was basically full of exclamations.

"This author is a tentacle monster.,20,000 words a day.,It's so scary.。 ”

"Dianniang has had several dragon gods in the past few days, all of them are 20,000+ per day, I suspect that it is produced by the studio, and many people work together. ”

"20,000 words a day update, it's so cool to read......"

Chen Xu laughed, "Well, not bad, not bad! Work hard, I guarantee that you will earn more than 10,000 yuan a month." ”

Hearing Chen Xu's words, Wang Wei, Wu Zhiqiang and Xu Xiaoyan couldn't help but smile happily. There is no reward more practical than money.

After laughing for a while, and then chatting about the outline of the new book, Wang Wei suddenly thought of one thing and said: "Ask you something Chen Xu, you are studying computers, can you crack the red envelope plug-in?"

The red envelopes sent in the group are often forced to be shot by those zombie fans.

That's it, some fans send monthly tickets and recommended tickets red envelopes to increase the exposure of the book, but unfortunately 99 out of 100 are hanging, and they can't be grabbed at all. ”

"Red envelope plug-in, ......" is the general principle, Chen Xu knows.

At present, there are three main ways to automatically grab red envelopes on the market, the first is to use auxiliary functions and notification bar message interception to remind users as soon as the red envelopes come;

Second, use the Xposed framework to hook the red envelope function;

The third way: directly modify the code of the app with the function of grabbing red envelopes, and package and install it for the second time.

But he didn't study how to crack it, so he pretended to bow his head and coughed, and then said, "Xiaobai, how to crack the red envelope plug-in?"

After he sat up straight, Xiaobai had already said in his ear: "According to the characteristics of grabbing red envelopes, under normal circumstances, grabbing a red envelope requires three scenes: accepting the red envelope message, manually clicking on the red envelope, and opening the red envelope animation.

According to the average network speed and people's reaction speed, the time it takes to grab a red envelope is about 4s-5s.

After this time, it can basically be judged that the red envelope plug-in is used.

According to this idea, you can write a jamming plugin, hang an anti-sniffing plugin before sending red packets, and use dynamic IDs to automatically send text red packets.

Although this cannot 100% prevent all kinds of plug-ins, it can make most of the plug-ins that listen to the red envelope event invalid. ”

Wang Wei asked, "Is it okay?"

Chen Xu nodded and smiled: "No problem." ”

This time, it didn't take a small white shot, Chen Xu personally began to write an anti-sniffing plug-in.

Under Xiaobai's guidance, he began to crack the code in C.

Someone to guide and their own programming are completely different things, there is no jam, and there is no BUG, because there is a white code supervision in a code, and it is impossible to make mistakes.

The anti-sniff plug-in has a single function and very simple code, with less than 300 lines, so it was written in less than an hour.

didn't even run it for a trial run, so he directly asked Wang Wei to hang up the anti-sniffing plug-in, and then asked Wu Zhiqiang to send a red envelope in the book friend group.

"Honey is so sweet that it robbed you of your red envelope. ”

"Lao Tzu will fly and snatch your red envelope. ”

"It's weird, it's strong, you grabbed your red envelope first. ”

"My girlfriend's diabetes caused me tooth decay and robbed you of your red envelope. ”

“……”

1, 2, 3, 4, 5, 6, 7......

In a group of 300 people, 50 red envelopes took 17 seconds to grab, and Wang Wei and Wu Zhiqiang were dumbfounded, "Damn! I have never sent red envelopes for more than 5 seconds before, and I basically grabbed them within three seconds." ”

"I can't rob those gang of hangers by sending red envelopes myself. ”

"yes. Every time they give out a red envelope, when I click on it, there is only a red envelope left. ”

Just when Wang Wei, Wu Zhiqiang and Xu Xiaoyan were talking excitedly, the group had already exploded.

"This red envelope is poisonous ......"

"Toxic +1. ”

"Hahaha, I finally grabbed the red envelope. ”

"Thank you to the owner. The first time I grabbed a red envelope in the group. ”

“……”

Watching the discussion of the group, everyone laughed.

Then I hung up the Dianniang APP and sent a red envelope for a recommendation ticket, this time it was even more ruthless, and there was no movement in those ten seconds.

Then someone in the book friend group shouted, "The latest chapter has a big package of recommendation votes, I just grabbed one, everyone has a recommendation vote and didn't vote to grab it." ”

The group friends made a "terrifying" expression and said: "The big guy is really a unicorn arm, and he can actually snatch those hangers, admire and admire." ”

At this moment, another group friend, Jingyanggang, was beaten and said: ", you can really grab it, everyone go and grab it." After speaking, he also sent a screenshot.

Soon the group became agitated, and everyone went to watch......

A red envelope for a recommendation ticket was snatched up after 3 minutes, which is simply incredible.

Some people thought that the point girl program ape had finally taken action to deal with the hanging party, and also sent a red envelope to experiment, but it was shot in two seconds.

Some smart group members deduced from the red envelopes in the previous group that this should be loaded with anti-cheat software.

Someone @ group leader Wang Wei asked him if it was in the end.

Under Chen Xu's instructions, Wang Wei generously admitted it, and @ all staff, the script will be hung in the group space when it comes back, and whoever wants to send red envelopes in the future must remember to hang an anti-sniffing script first.

Talking and laughing, time flies.

Chen Xu took the time to look at the time, it was almost 7 o'clock, and said, "You haven't eaten yet, let's go, let's eat together......"

……

The next day was Saturday, and it was cold and windy outside the window.

In the morning, Chen Xu contacted the animation production company, and the reply was that the picture would be released this afternoon.

I watched a movie with Xiaobai at home, and at ten o'clock a strange phone call came, and when I picked it up, it was Duke, the digital blogger and DIY maniac, called.

Chen Xu remembered that the two had left each other's phone numbers before, but he didn't save each other's.

Duke tells him that he's in BJ and is at a hot drink bar near College Town.

After hanging up the phone, Chen Xu immediately rushed over.

Duke is a four-eyed boy in his early 30s, with a strong body and dark skin, wearing a jacket + jeans + black low boots, and a rucksack on the ground next to him, which looks no different from the average programmer ape outfit.

"Thank you, thank you, it's so much trouble. Chen Xu stretched out his hand and shook Duke's hand, "Actually, the courier will do, or call me and ask me to come and get it." ”

Duke smiled, "It's okay, just drop by." I love to travel everywhere and every time I go to a new city, that new experience inspires me a lot. ”

Chen Xu smiled: "I really envy ......"

After the two chatted for a while, the conversation quickly shifted to DIY.

Duke took out a dictionary-sized album from his bag, opened it, flipped to one of the pages, and handed it to Chen Xu.

Above is a photo of Duke and a large white box, which is about the size of a household microwave oven, boxy, with many switch hubs and indicator lights on the front.

Chen Xu took a closer look, and the bottom of this white box was printed with the words Magic-1 Homebrew CPU.

He paused for a moment, came back to his senses and said in surprise: "Damn, this is the CPU?"

Duke smiled and said, "Yes, this is indeed the CPU. It was a guy named Bill Bouzby, who soldered the CPU by hand in 2005. ”

Chen Xu: "...... Awesome. ”

Duke smiled and flipped through the atlas, which was the internal structure of the CPU, with dense memory boards, register lines denser than cobwebs, and control cards stacked together to make people feel dense phobia......

"Bouzby worked hard for four years and made this all-handmade CPU with his own efforts.

This fully manual CPU can support full hardware address translation, memory insinuation IO and DMA, and support multi-process, with a main frequency of 3MHz.

The CPU uses an 8-bit address bus, and each process has 128K address space, including 32 2K data pages and 32 2K code pages, which are projected into the 22-bit physical address space, which is the 23-bit physical address space if you count the address space of external devices. ”

After a pause, Duke said, "What's even more powerful is that he used this CPU to build a computer, and the name is Magic-1."

The computer consists of two serial ports and a 20M 1.3-inch hard drive and another 30M hard drive. To get the system up and running, Buzbee ported the LLC compiler to it.

In addition, he uses this computer as a web server and supports TELNET sessions!

Magic-1 Homebrew won Bouzby the Grand Prize at the 2005 World Maker Competition. ”

Chen Xu listened almost on his knees, what kind of handicraft experts and DIY maniacs he was aiming at were all scum in front of this kind of god with super strong hands-on ability......

ps: It seems that I can't do the brush~ Yesterday I briefly went to the tenth place on the new book list, and today I was brushed down again. But thank you very much for the book friends who voted for the reward.
