Chapter 145 It Has Great Value and Significance (Part 2)
Su Ho likes Su Xiaomu like this very much.

Like an older child, there is one-third innocent, one-quarter relaxed, one-fifth leisurely, one-sixth proud, one-seventh proud, and one-eighth carefree.

emmm~
This is the vanity and sense of accomplishment of being an older parent.

Su Xiaomu looked at the ceiling, "Huh, you seem a little bit overwhelmed?"

rub rub...

Rubbing again...

"Give me the two improved file systems." Su Ho said expressionlessly.

With a soft figure, she quietly took half a step back, beeping loudly in her heart, "Damn rascal!"

"Pooh!"

"Biu shame!"

"It's cheap and good!"

The feeling of being subdued was gone, Su Xiaomu turned around and saw Su Ho's expressionless face, and his heart shuddered.

Although he has never eaten pork or seen pigs running, if he still can't figure it out at this time, he is mentally retarded.

In his mind, he clearly knew that at such a time, he had to play dumb.

He pretended that nothing happened, and saved the complete system package and the individual package of the two file systems respectively in compressed file format, stored them in a USB flash drive, and gave them to Su Ho.

"Which day next week will you be free, how many people will you meet with me?" Su Ho said casually while fiddling with the USB flash drive with his right hand.

Su Xiaomu thought for a while, and instead of answering directly, he asked, "Do you want to commercialize it?"

Speaking of which, this was the first time that Su Xiaomu discussed business-related matters with Su Ho.

"It has great value and significance, you should know it." So Ho said.

Of course Su Xiaomu knew.

Whether it is Android or Linux, these have nothing to do with China.

When it comes to fuse and sdcardfs, they have nothing to do with China.

Fuse is a user space file system. The reason for its birth is a virtual file system created by Android in order to control the permissions of different APPs to access files.

Because the efficiency of the actual file system ext4 is not high, Samsung based on warpfs secondary development except sdcardfs.

In direct comparison, the user needs to go through 4 interactions to transfer the data of the real ext6 file system through fuse, while sdcardfs only needs to go through two times.

It is reported that sdcardfs is infinitely close to the performance of ext4.

More and more domestic mobile phones choose sdcardfs, and they will also specifically point out the lightning-fast response speed in the promotional documents.

However, it is said that a large domestic manufacturer released scattered news that it will launch a scary technology this year, and online speculation is a new file system.

Therefore, Su Xiaomu is not the only one who wants to change the phenomenon of domestic high-tech weakness that has been weak for many years.

But in any case, the significance of the launch of sdfs lies in the fact that it can be truly and reliably crowned with the word "made in China", and the impact will be far-reaching.

So, how good is the sdfs that Su Xiaomu named casually?
To put it simply, although both sdfs and sdcardfs have to go through two interactions, sdfs improves the overall performance and efficiency of sdcardfs by 2%.

Some aspects, such as reducing file fragmentation and reducing the generation of APP garbage data, have greater advantages.

"I know, but my next plan is to rewrite the Android underlying file system." Su Xiaomu raised his eyebrows and said it calmly.

After the second development of sdfs, Su Xiaomu saw more of his thoughts on Android.

Suho: "..."

"how long it takes?"

"It was impossible a year ago." Su Xiaomu thought for a while, and quickly gave an answer.

It was only a few days ago, and the real file system was to be rewritten, and the algorithm was very troublesome, at least we had to finish manipulating the set of storage that was still in Wan's Small Finance.

Su Ho snorted, glanced at Su Xiaomu and said, "My personal suggestion is to take this opportunity to launch sdfs first. It's a warm-up. Step by step, there must be some foundation to have trust."

"What you said makes sense. There are practical problems in it. Even if it is excellent, it may not be adopted by Linux or Android." Su Xiaomu sighed.

On the contrary, if you just modify the virtual SD card file system, you don't need Android or Linux approval.

Originally, it supports in-depth customization. Although Android is also upgrading the system to close the loop, it has not yet reached that point.

Suho made a gesture, "Then you prepare and set aside some time next week."

…………

…………

Tuesday, January 1th, the 16th day of the winter month of the lunar calendar.

There was no exam arrangement for the whole day, but Su Xiaomu still got up early, walked to Su Ho's house as usual with his slippers drooping.

He and Suho, who also just woke up, snorted and washed at the sink.

Sometimes Su Xiaomu would also think:
Do I have my own home?

some!

Which side is farther.

Soho's house is far away, so I have to walk to a balcony!

Is there water in the house, and are there any toiletries?

Yes, I have.

Then why not wash at home?
got used to……

"Noodles in the morning." Su He finished washing faster than Su Xiaomu, a few minutes earlier, and did not apply makeup.

Su Xiaomu hummed, and handed Su Ho a glass of water...

After breakfast, Soho said, "Drive your Land Rover."

Wanda was the only one who knew about this Land Rover Soho when she bought it, so no one actually knew that it was her car before.

Only drove it three times before turning it into a used car.

Therefore, the general meaning of driving a Land Rover to go out is different.

"The person you're going to see later is regarded as having a relationship, and you can say whatever you want, although you have always been like this."

On the way, Su Ho briefly introduced the situation.

There are a few partners who can be regarded as Heqian. At Su He's invitation, they want to meet Su Xiaomu himself and have a chat.

Speaking of which, Yangcheng has a strong high-tech atmosphere in the whole country.

For example: take the lead in realizing the large-scale application of ODA (Offline Data Authentication, offline data authentication) new payment technology in China, that is, almost all public transportation (subway, APM) with gates support UnionPay IC credit card swiping and boarding, first boarding After deduction.

Take the lead in realizing the large-scale application of mobile APP scanning code to enter the station, etc., and so on.

Therefore, in essence, the atmosphere in Yangcheng is more receptive to the emergence of new high-tech technologies.

Su Xiaomu thought for a while and asked, "Will communication technology be needed?"

"Yes." Su Ho said firmly, "If there is no need for technical exchanges, you don't need to go."

The implication is actually more.

If you dig deeper, you will find many facts that cannot be hidden like sneezing.

Su Xiaomu said oh, and said, "It's the happiest I can see the boss again, and exchange technology and so on!"

For Xueba, he wished that every day would be such an opportunity.

Su·Xueba·Communication makes people progress·Xiaomu.
