Chapter 194 Brief Communication and Cooperation (Part 2)
Like all public occasions, Hong Feng's face is not rich in expression.

Su Xiaomu, a student at school, couldn't see through whether what he said was as ironic as what Su Ho said.

Old embarrassed!

But on the surface, Su Xiaomu remained calm and looked at Hong Feng with a smile on his face.

Hong Feng's resume appeared in his mind. For a top student, a quick memory of words is not a big problem.

Hong Feng, the co-founder and vice president of Yearning Technology, the father of Yearning Robots, graduated from Shanghai #Shanghai Jiaotong University with a bachelor's degree, and later obtained a master's degree in computer science from Purdue University in the United States.

This is also the degree that Su Xiaomu plans to obtain in the future.

Before founding Xiangxiang Technology, Hong Feng served as a series of product and engineering directors at Google and Siebel, leading or participating in projects such as Google Music, Google Pinyin Input Method, Google Calendar, and Google 3D Street View.

The sentence that Su Xiaomu remembers most is the original words of Remy, the founder and chairman of Longing Technology, when he commented on Hong Feng.

"You will feel a lot of pressure when you come into contact with him. He has no expression. He says whatever you want. You don't know what he thinks, but he is a very smart person."

Su Xiaomu felt the pressure right now, and the expression on Hong Feng's face had hardly changed since he came in.

However, the conversation hasn’t even started yet!
"President Su, you're being polite." Hong Feng made a gesture, his voice neither high nor low.

After a pause, he continued, "I heard that Mr. Su is still a student at school, did he ask for leave today?"

Su Xiaomu was stunned. Hong Feng's sudden start of greetings was really unexpected.

Aren't you expressionless? I was very stressed just now.

Why are you still talking about it.

"Lao Hong is always concerned. The class on Friday is in the afternoon." Although he was stunned for a moment, Su Xiaomu replied with a smile on his face.

It suddenly occurred to me that today is the Lantern Festival, even if the atmosphere of the festival is very light, even if there is no holiday, it is still a festival.

Hong Feng chatted with Su Xiaomu one after another, not to the point of checking the household registration.

Su Xiaomu said before that he was a follower of the crowd, Hong Feng raised the topic, but he didn't change it.

Although in fact he drifts with the crowd in many ways.

In the end, Hong Feng glanced at Su Xiaomu and said with emotion, "Boss Su is really a lucky person."

Su Xiaomu didn't know why, so he didn't answer.

Hong Feng made a gesture, and then said, "About sdfs, a virtual SD card file system, I have some questions and would like to ask President Su, and I hope that President Su will not hesitate to enlighten me."

After exchanging pleasantries, we finally got to the point.

This is why Hong Feng must meet Su Xiaomu.

Hong Feng is a technical officer, and MUI is the product he is responsible for. MUI is a domestic UI based on Android with secondary tailoring and design. For example, the file system used on the virtual SD card is sdcardfs.

Moreover, in the past 2017, several new products released by Xiangxiang Technology have advertised this file system as fast as lightning.

Su Xiaomu nodded and made a gesture of invitation, "Boss Hong, please speak."

But I was thinking in my heart, Hong Feng wouldn't have prepared hundreds of interview questions just like Lei Mi's mutual interview when he followed up with Longing for Technology, right?

Hong Feng's first question directly hit the core of the sdfs file system.

"As far as I know, the sdfs2.0 based on ufs1.1 and above flash memory can be improved by 15% on the basis of sdcardfs, which should be the limit?"

"We have done a vision model test for technology, and the approximate result is this."

It is undeniable that the R&D laboratory of any major factory is very high-level. In many cases, it is not that it cannot be done, but that it is not enough energy to do such a time-costly project.

Any company will pursue profit. Due to various considerations, if the rate of return cannot meet expectations, it will be put on hold indefinitely.

Until it has to be done, or as it is now, when there is a finished product, just bring it.

Su Xiaomu nodded, "This is already the best data structure algorithm at the moment. In the past few months, I have tried various efforts, but I can't break through."

After a pause, he said, "Unless you sacrifice some stability."

Hong Feng continued, "Can I have a look at the long-term continuous operation stability data of sdfs?"

Receiving Su Ho's reminder, Su Xiaomu brought in a notebook, which would call up the data to show Hong Feng, and said, "Honestly speaking, I think the patience of the current users is pretty good.

Since the integration of smartphones, there is no need to replace the battery, and the number of phone restarts has become less and less. This is equivalent to requiring that the performance of the mobile phone in all aspects is comparable to that of the server.

Especially long-term stability.

However, when users feel that the mobile phone is running too slow, they often restart and reset all modules on their own.

When selecting the algorithm, the stability of sdfs is fully considered when the machine is running continuously for a long time. "

To be honest, Su Xiaomu felt that the mobile phone with a replaceable battery in the past was a bit of a rogue in a certain way. If the battery ran out, the phone had to be restarted and all modules would be reset.

In a sense, it is equivalent to reducing the lag of the mobile phone to the Schrödinger level.

While Su Xiaomu was talking, Hong Feng read all the data and nodded, "The data of sdfs is better than I imagined."

In fact, he has already obtained all the test data from the internal laboratory of Yearning Technology, which is slightly exaggerated than the one that Su Xiaomu gave.

Su Xiaomu is an honest person, he doesn't like to exaggerate, he can do as much as he wants.

After a very in-depth exchange at the technical level, Hong Feng continued, "Nasu always thinks what are the advantages of sdfs in the current environment."

There was no time for Su Xiaomu to react at all, and the questions came one after another.

Su Xiaomu thought for a while and replied, "Actually, I don't know how to answer this question."

"Theoretically speaking, if all the 1.2 million times of freezes in the current Android ecosystem are replaced with SDFS, it will reduce more than 15.00 million times because of the 4000% all-round improvement.

But specific to each operation of each user, there may be almost no feeling.

Especially now that the hardware stack in the Android ecosystem is getting higher and higher, through higher-performance hardware, it can avoid lagging in some aspects, but lagging will not disappear. "

Hong Feng took a deep look at the honest Su Xiaomu and said.

"President Su, I may know why you are so lucky."

"Let's talk about the authorization fee. I believe that the sdfs file system has done the best in the current environment. Only by modifying the Android underlying file system ext4 can we get a qualitative leap. We yearn for technology that needs this A virtual SD card file system is added to MUI."

As for the issue of adaptation, it should not be discussed today.

He thought it was a happy situation for everyone, but Hong Feng saw Su Xiaomu waved his hands hastily, "This, this, this cooperation has to be done with Su Ho, I'm not very good at..."

PS: The second update is here, and the third update has to wait.

I'm very tired, I don't know why, I stay up until five in the morning and get up to work...
