As in public, the expression on Hong Feng's face was not rich.

So that Su Xiaomu, a student at school, couldn't see through whether what he said was ironed like what Soho said.

It's embarrassing!

However, on the surface, Su Xiaomu was not moved at all, and still looked at Hong Feng with a smile.

Hong Feng's resume appeared in his mind, and for Xueba, a little literal quick memory is not a big problem.

Hong Feng, co-founder and vice president of Longing Technology, and the father of Longing Robot, graduated from Shanghai #Haijiao 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 is going to get in the future.

Prior to founding Yearning Technology, Feng held a series of product and engineering executive positions at Google and Siebel, leading or participating in projects such as Google Music, Google Pinyin Input Method, Google Calendar, and Google 3D Street View.

Su Xiaomu remembered the deepest sentence, yearning for the original words of the founder, chairman and CEO of Longing Technology, Remy, who commented on Hong Feng.

"You're stressed when you touch him, he doesn't have an expression, he says whatever you want, you don't know what he thinks, but he's a very smart guy. ”

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

However, the conversation has not yet begun!

Mr. Su was 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 now, did he come out on leave today?"

Su Xiaomu was stunned in his heart, Hong Feng's sudden greetings were really unexpected.

Isn't it expressionless, I was still under a lot of pressure just now.

How can this still be a greeting.

"Lao Hong always cares, and Friday's class is in the afternoon. Although he was stunned in his heart, Su Xiaomu replied with a smile on the surface.

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, but the size is still a festival.

Hong Feng and Su Xiaomu chatted with each other, not to the point of checking the household registration.

Su Xiaomu had said before that he was a person who went with the flow, and Hong Feng didn't fork the topic when he started it.

Although in fact, there are many ways for him to go with the flow.

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

Su Xiaomu didn't know why, so he didn't say anything.

Hong Feng made a gesture, and then said, "I have some questions about the virtual SD card file system of sdfs, and I hope that Mr. Su will give me advice." ”

After the greetings, I finally got to the point.

This is also the reason why Hong Feng must see Su Xiaomu.

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

And in the past 2017, on several new products released by Yearning Technology, this file system has been advertised as lightning fast.

Su Xiaomu nodded and made a gesture of please, "Mr. Hong, please speak." ”

But I was thinking in my heart, Hong Feng wouldn't follow up on the yearning for technology, and he prepared hundreds of interview questions like Remy's mutual interview, right?

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

"As far as I know, SDFS1.1 based on UFS2.0 or above flash memory can be improved by 15% on the basis of SDCARDFS, right?"

"We did a long-term model test with technology, and the results were probably like this. ”

It is undeniable that the R&D laboratory of any large factory is very level, and many times it is not that it cannot be done, but that it is not enough energy to do such a project with high time cost.

Any company will chase profits, and for all reasons, the rate of return will not meet expectations and will be put on hold indefinitely.

Until it has to be done, or as it is now, there is already a finished product, and you can bring it.

Su Xiaomu nodded, "This is already the best data structure algorithm at the moment, and in the past few months, I have tried all kinds of efforts, but I have not been able to break through." ”

After a pause, he said, "Unless some stability is sacrificed." ”

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

Su He prompted, Su Xiaomu brought a notebook in, which would call up the data to Hong Feng, and said, "To be honest, I think the patience of users is still good."

Since the integration of smartphones, there is no need to replace the battery, and the number of phone restarts is becoming less and less, which is equivalent to requiring all aspects of the phone's performance to be comparable to the performance of the server.

Especially long-term sustained stability.

However, today's users often restart their phones and reset all modules when they feel that their phones are too stuck.

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

To be honest, Su Xiaomu felt that the previous mobile phone with a replaceable battery was a bit of a chicken thief in some way, and if the battery was replaced when it ran out of power, the machine had to be restarted, and all modules would be reset.

In a sense, it is equivalent to making the lag of the mobile phone Schrödinger reduced.

While Su Xiaomu spoke, Hong Feng read all the data and nodded, "The data of SDFS is better than I imagined. ”

In fact, he had already obtained all the test data from the internal laboratory of Longing Technology, which was slightly more exaggerated than the one that Su Xiaomu took out.

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

After a very in-depth exchange at the technical level, Hong Feng continued, "Na Su always thinks that SDFS has any advantages in the current environment. ”

didn't give Su Xiaomu time to react at all, and the questions were one after another.

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

"Theoretically speaking, if all the 120 million times a day in the Android ecosystem are replaced with SDFS, they will be reduced by more than 40 million times because of this 15% all-round improvement.

But when it comes to every action of each user, there may be little to no feeling.

Especially now that the hardware stack of the Android ecosystem is getting higher and higher, through higher-performance hardware, Caton has been avoided in some aspects, but Caton will not disappear. ”

Hong Feng looked at the honest Su Xiaomu deeply and said.

"Mr. Su, I may know why your luck is so good. ”

"Let's talk about the license fee,sdfs this file system,I believe that the number of wood has done the best in the existing environment,Unless you modify the underlying file system of Android,ext4It is possible to get a qualitative leap,We yearn for technology to need this virtual SD card file system to add to MUI。 ”

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

I thought it was a happy situation, but Hong Feng saw Su Xiaomu hurriedly waved his hand, "This and this, I have to find Su He for this cooperation, I don't know how to ......."

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