Chapter 189 Temporary Communication and Cooperation
Like all public occasions, the expression on Hong Feng's face was not rich.
Su Xiaomu, a student at school, couldn't tell whether what he said was as good as Su Ho said.
It’s so embarrassing!
But on the surface, Su Xiaomu remained calm at all, still looking at Hong Feng with a smile.
Hong Feng's resume appeared in his mind. For an academic master, a little quick memory of words is not a big problem.
Hong Feng, co-founder and vice president of Longing Technology and the father of Longing Robot, graduated from Shanghai Jiao Tong 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 Longing Technology, Hong Feng held a series of product and engineering supervisor jobs 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 the most is the original words of Remi, the founder and CEO 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 and he can say whatever you want. You don't know what he thinks, but he is a very smart person."
Su Xiaomu felt the pressure now. The expression on Hong Feng's face had hardly changed since he came in.
However, the conversation has not yet begun!
"Mr. Su, you're welcome." 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 you 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 this?
"Mr. Lao Hong is concerned, Friday's classes are in the afternoon." Although she was stunned for a moment, Su Xiaomu replied with a smile on her face.
I suddenly remembered 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 and Su Xiaomu kept chatting, but it didn't go as far as checking their household registration.
Su Xiaomu has said before that he is a person who goes with the flow. When Hong Feng brought up the topic, he did not change it.
Although in fact there are many ways for him to follow the crowd.
At the end, Hong Feng glanced at Su Xiaomu and said with emotion, "Mr. Su is really a very lucky person."
Su Xiaomu didn't know why, so he didn't answer.
Hong Feng made a gesture and then said, "I have some questions about the sdfs virtual SD card file system that I would like to ask Mr. Su, and I hope that Mr. Su will give you some advice."
After exchanging pleasantries, we finally got down to business.
This is why Hong Feng must see 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 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 all promoted this file system as being as fast as lightning.
Su Xiaomu nodded and made a gesture of invitation, "Mr. Hong, please speak."
But I was thinking, Hong Feng would not have prepared hundreds of interview questions just like Remy did when he was pursuing technology, right?
Hong Feng's first question went straight to the core of the sdfs file system.
"As far as I know, sdfs1.1 based on ufs2.0 or above flash memory can improve the overall performance by 15% on the basis of sdcardfs, which should be the limit, right?"
"We have conducted a long-term model test on Longing Technology, and the approximate result is this."
It is undeniable that the R&D laboratories of any major manufacturer are very high-level. In many cases, it is not that they cannot do it, but that they do not have the energy to do such a time-costly project.
Any company will pursue profits. Due to various considerations, if the rate of return cannot meet expectations, it will be shelved indefinitely.
Until you have to do it, or like now, you already have the 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 and failed to break through."
After a pause, he said, "Unless you sacrifice some stability."
Hong Feng continued, "Can I see the data on the long-term continuous operation stability of sdfs?"
After receiving Su Ho's prompt, Su Xiaomu brought a notebook in, then pulled up the data and showed it to Hong Feng, and said, "Honestly, I think the current users' tolerance level is quite 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 all aspects of the performance of the phone to be comparable to the performance of the server.
Especially long-term sustained stability.
However, when current users feel that their mobile phones are running too laggy, they often restart and reset all modules on their own.
When selecting algorithms, we fully consider the stability of SDFS when the machine continues to run for a long time."
To be honest, Su Xiaomu felt that the previous mobile phones with replaceable batteries were a bit of a thief in some aspects. When the battery was out of power, the machine 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 thought."
In fact, he has obtained all the test data from the internal laboratory of Xiangxiang Technology, which is slightly more exaggerated than what Su Xiaomu presented.
Su Xiaomu is an honest person and doesn't like to exaggerate. He always says as much as he needs to.
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."
Without giving Su Xiaomu any time to react, the questions came one after another.
Su Xiaomu thought for a moment and replied, "Actually, I don't know how to answer this question."
"Theoretically, if all the 120 million lags in the current Android ecosystem every day were replaced with SDFS, more than 40 million would be reduced due to this 15% all-round improvement.
But specifically for every 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, lags can be avoided in some aspects, but lags will not disappear."
Hong Feng looked deeply at the sincere Su Xiaomu and said.
"Mr. Su, I may know why you are so lucky."
"Let's talk about licensing fees. I believe that the SDFS file system has done its best under the current environment. Only by modifying the Android underlying file system ext4 can we achieve a qualitative leap. We yearn for technology that requires this
A virtual sd card file system is added to mui."
As for the issue of adaptation, it shouldn’t be discussed today.
He thought it was a happy situation for everyone, but Hong Feng saw Su Xiaomu wave his hands hurriedly, "This, this, this cooperation has to be dealt with by Su Ho. I'm not very good at it..."

ps: The second update is here, the third update has to wait.
I am very tired. I don’t know why, but I stay up until five o’clock in the morning and still get up to work...
