After lingering with Ye Qingchen, Lu Zhou rushed to Guangnan Airport after lunch.

Two and a half hours later, the plane arrived at Beijing Airport.

After getting into the taxi, Lu Zhou continued to refine the idea of ​​WeChat using his laptop in the car. It was not until six o'clock that the vehicle drove into the Zhongguancun area.

Qiandu's headquarters is located in Shangdi Science and Technology Park. After being listed on Nasdaq in 2005, Qiandu spent 100 million yuan to purchase this land to build its headquarters.

Later, the designer of the "Bird's Nest" designed this building for Qiandu, and the building was topped out in the same year of the Olympic Games.

Lu Zhou had passed by this place many times in his previous life. Although he secretly complained about its strong "Bird's Nest" wind countless times, it was hard to tell whether he felt envious of him in his heart.

Even though it later attracted public disdain due to various product problems, it has to be admitted that it still represents the top power of China Internet.

When he arrived near the building, he called Cheng Xuyuan.

After a while, Cheng Xuyuan came downstairs.

Lu Zhou met Cheng Xuyuan again, but there was no change from what he remembered. He was younger and more energetic.

Although the name Dad and Mom completely represents his life experience up to now, he doesn't look like the ordinary person's image of a science and engineering man or a programmer.

He was dressed in a black punk style, with half-long hair tied in a ponytail. He looked more artistic and more like a rock star.

Lu Zhou was half a head taller than him. Before coming here, he was afraid that the capital would be cooler, so he specially put on a blue sweatshirt, making him look like a freshly graduated college student.

The duo with very different styles stood in front of the Qiandu Building, attracting some people's attention from time to time.

Cheng Xuyuan handed Lu Zhou a cigarette and lit one himself.

Lu Zhou looked at the beard on half of his face, coupled with the cigarette held between his fingers, "He still looks like a prodigal son," he thought.

Cheng Xuyuan said, "You kid, you really come as soon as you say. You usually don't contact me once for two or three months, but this time it's good, you just call me right away."

Lu Zhou smiled and replied, "Aren't you in a hurry to recruit Master Cheng? You can't be in a hurry."

After hearing this, Cheng Xuyuan joked, "Come on, I've been so busy lately that I have to ask for leave just to meet with you. It's not like you, Boss Lu, who leaves and comes whenever he wants."

"Oh? So busy? What business are you busy with?"

"I won't say any more, just two words 'Sogou', let me imagine the rest."

When Lu Zhou heard this, he followed his memory to find out the details. After Sohu split Sogou, Sogou immediately launched its search business.

It directly challenged Qiandu on the frontal battlefield, and then used search engine technology to launch Huaxia's "Internet Input Method", and then used the browser as a sharp edge to try to break through Qiandu's high wall.

And now Cheng Xuyuan is working at Qiandu, which involves nothing more than one of the above.

"Input method?" Lu Zhou asked uncertainly.

After all, Qiandu search is already dominant. Sogou can threaten Qiandu through input methods and browsers. In particular, the input method’s share in China has remained high all year round.

Cheng Xuyuan and Lu Zhou were walking side by side to a nearby restaurant when they suddenly heard three words spoken by Lu Zhou, and their expressions suddenly changed.

Qiandu's input method project at this time was being developed in secret. Cheng Xuyuan only thought that Lu Zhou would guess that Qiandu would continue to suppress Sogou's search business.

Cheng Xuyuan didn't know that Lu Zhou's sense of smell was so sensitive. He hurriedly said, "Pretend I didn't say anything."

And Lu Zhou also made an "ok" gesture, "Then why do I need you to resolve the matter of the network alliance?"

"It's a long story. I hold several positions now. Although I'm not the main manager, I'm so busy every day that I can't find anything to do. This restaurant will do."

Cheng Xuyuan pointed to the barbecue restaurant in front.

"Okay. It doesn't matter."

After entering the store, the two of them took the ingredients and put them on the table.

Lu Zhou put the raw beef into the iron plate and said, "How about it, are you interested in starting a business together?"

"Sizzling", when the raw beef comes into contact with the hot iron plate, it makes a sound and then emits aroma.

Cheng Xuyuan threw the mutton in, "It's too early. I haven't mastered my skills yet, so it doesn't make much sense to go out now."

Lu Zhou smiled, "Then you just mentioned me. In terms of technology, I am not as good as you."

Cheng Xuyuan turned the mutton over and said, "No. I'm just talking about myself. You're making things famous."

"Let me ask you a few questions."

"explain."

"Distributed classic problem, when was the Byzantine problem proposed?"

When Cheng Xuyuan heard this, he was stunned for a moment and didn't understand Lu Zhou's intention. "Mport's paper in the 1980s was at least earlier than we were born."

“What are the industry’s practical attempts to address this issue?”

After hearing this, Cheng Xuyuan thought for a while, "In 1990, Lesile then mentioned paxos. Although it cannot really solve the problem, it should be the most effective consensus protocol method in non-Byzantine systems at present.

PBFT in 1999 was later optimized from exponential algorithm to polynomial level.

Apache HDFS is one thing that can really be used.

The POW proposed by Satoshi in the past two years is barely considered, and he even got a Bitcoin running, although talking about performance may be a joke."

Cheng Xuyuan picked up the mutton, dipped it in the sauce and put it into his mouth, "You ask me what this thing is for, are you trying to test me?"

Lu Zhou continued, "Your company should also be studying related issues."

"Indeed. There is no company that doesn't pay attention. What's more, Amazon has also involved the concept of cloud computing. It is difficult to explain clearly what the cloud is, and no one except Amazon really does it. But its own business must be distributed, so if you don't study

Waiting for the system to cool down?"

Lu Zhou took the beef and said, "Okay. It may take more than ten years from the genius' idea to the final implementation. But one day, sooner or later it will be realized."

"So? What do you want to express?"

Lu Zhou said with a smile, "There is no limit to technology. Admit it, everyone is not a genius. If your skills are not good enough, you will still not be good enough in fifty years."

"..."

Cheng Xuyuan said helplessly, "You have made such a big detour just to hurt me?"

"Isn't this, by the way, a review of the research you did when you were still in school?"

The two looked at each other for a moment and laughed.

Another round of meat slices is lowered onto the iron plate.

Cheng Xuyuan raised his glass and said, "That's what it sounds like, but if you think about it carefully, you will realize that you are talking nonsense. Those are all theoretical research, and we are nothing more than practitioners who learn the ideas and implement them with programs. Not to mention the in-between

Implementation and construction of a large-scale system, those who have not experienced it will not know the difficulties involved."

"So, at least let me go through a huge system worth hundreds of millions, otherwise I will have to live in a thousand degrees."

Lu Zhou also raised the cup in his hand and touched it with Cheng Xuyuan.

"Okay! That makes sense. As for Qiandu Ali Penguin, any of these giants that are active today didn't start from scratch. According to you, none of them can do it. The fact is, from zero to millions

, to billions, they are all realized through exploration.

At least, you can't feel that you are different from Robin and the other three, and you have to wait until you have experienced it before you take action."

Cheng Xuyuan shook his head, "Then have you ever thought about how many corpses they trampled under their feet? Didn't they start from scratch to death?

Are you a newborn calf not afraid of tigers, or are you really not afraid?"

Lu Zhou laughed loudly, "It's just death, it's no big deal. The worst is to start over."
