Chapter 275 Walking on Two Legs

After a full 15 minutes, Su Xiaomu looked at the blank debugging file and fell into deep thought.

In the past 15 minutes, Su Xiaomu only did one thing, restore the downtime iMac Pro.

Fortunately, Apple's macOS is not complicated as a whole, and it doesn't take too much effort for Su Xiaomu to recover from scratch.

As for why Su Xiaomu spent 15 minutes...

Very simple.

For about eight and a half minutes, Su Xiaomu wondered whether it would be useful to restore the operating system to the state before it crashed.

This process is like Schrödinger thinking about the famous superposition thought experiment of life and death of cats.

As long as the result does not collapse until the last moment, it is absolutely impossible to know the result.

Su Xiaomu thought that if he gave up halfway, the experiment would not be complete.

On the other hand, I thought, if it doesn't work until the end, these 15 minutes are enough to do a new wave of debugging...

"Oh, today is not suitable for doing things!"

The right time, place and people are not there.

Speaking of which, Su Xiaomu also thought about many other things in these 15 minutes.

In general, it can be regarded as an extended branch of regret.

For example, why don't you make instant snapshots when debugging like an ordinary student. ①
For example, why do you want to provoke the firewall that you personally built and deployed on the supercomputer when the data is not archived.

It is a pity that there is no regret medicine in the world.

There is no way but to wish myself a happy April Fool's Day!
When thinking about this, Su Xiaomu's heart moved, "Why don't you try to develop a data recovery program to get back the lost data and status?"

"It seems that I can't make it in time..."

All magnetic hard disks can be rewritable. When Su Xiaomu tried to restore the system state to the time he needed, new data had already been generated, logically speaking, the original data had been overwritten.

Not to mention pristine condition.

If you can still think of a way to overwrite the original data, take the data recovery software on the market as an example, which can also support the retrieval of a lot of data.

but……

Get back the status...

In Su Xiaomu's impression, there should be no such software on the market.

The market demand is not large, because when operating important data status, system status, running status, etc., there is basically a process of setting up automatic snapshots.

Take storage as an example, any manufacturer's storage must have such a function.

Other vendors have more sophisticated, very adaptable snapshot capabilities.

"Shi Lezhi! With this time, it's better to go through the debugging process again. Although the same flowers will not bloom, it is another type of industrial test..." Su Xiaomu comforted himself.

If there is a market for the software that restores the status without snapshot operation, Su Xiaomu is still willing to spend some time tinkering with it, which is still a way to make money.

Even if he doesn't understand business or the market, this kind of thing can be left to Su Ho.

After looking at the time, it was only early eleven o'clock, and Su Xiaomu decisively entered the second wave of debugging and testing process. Anyway, the program he wrote was ready-made, and it was nothing more than modifying some things.

Seeing the test results output continuously, Su Xiaomu began to beep softly.

"Probably the best news today, the file system is really good..."

"..."

"All that's left is to walk on two legs..."

Su Xiaomu breathed a sigh of relief.

The general direction of the two debugging results is good, and the next thing will become clear.

As the core module of the storage operating system, the storage file system will of course be embedded in the bankrupt storage operating system based on the Solaris operating system to run a wave of simulation tests, just like the Android underlying file system.

There's actually something going on here.

Su Xiaomu's initial architectural idea was derived from the ZFS file system of Solaris. From a certain point of view, the Solaris system has ZFS for storage.

In other words, ZFS natively supports quite a few storage operations.

Therefore, the current testing of the first version of the storage file system with independent intellectual property rights is particularly important.

Of course, there are not so many resources available now, so we will use the test intensity of trillions of tests per second.

While conducting simulation tests, Su Xiaomu also had to take time to improve other core modules based on the file system.

Of course, Su Xiaomu didn't intend to make a general-purpose operating system, only for the storage field, and would try his best to cut out all the functional modules that were not needed to simplify the operating system.

There are many reasons, such as high-sounding time cost considerations and the like.

But in the final analysis, only by specializing in storage can Su Xiaomu be sure to rely on the existing knowledge and materials that have not been fully digested to complete...

Just as Su Xiaomu was watching that it was getting late and it was time to go to lunch, Su Ho's phone came in.

The first thing you hear when you connect is:

"Su Xiaomu, come out and eat together."

Su Xiaomu said, "Where is it?"

Su Ho gave an address, "... Come here quickly, today is also a foreign festival."

"It will be twelve o'clock soon, and the conventional rule is that fools are fools before 12 o'clock, you know? I'm an educated person." Su Xiaomu said casually.

While speaking, he had already got up and packed up to go out.

Su Ho choked on Su Xiaomu, and snorted, "Don't worry about me! I won't go as agreed, what's wrong?"

The phone was hung up, and Su Ho was still muttering.

"Oh, man, no fun!"

"Don't take us to heart at all!" Su Ho said with emphasis.

Wanda on the side nodded her head hummingly, "That's right, don't you know how to make do with us!"

"That's right, who is not a baby anymore!"

"Hmph, wronged, super wronged!"

The more Su Ho and Wanda's best friend talked, the more they felt that they were extremely wronged, and their usual shrewdness was thrown away.

They are just ordinary girls now.

Or the girl who has wronged her because of certain things.

Therefore, Suho and Wanda have shared the same hatred until the end, and made up their minds that today's April Fool's Day will be over!
To go with the conventions of it...

Su Xiaomu didn't expect that things would turn out like that later. Strictly speaking, it was the first time that Su Xiaomu found out that his temper was not very good in a certain situation.

Of course, Su Xiaomu didn't know this at this time. He didn't forget what Su Ho had specially reminded him that Phaeton needs to refuel when going out.

So I just took Martha's key and went out.

According to the location given by Su Ho, Su Xiaomu rushed over quickly.

I am still thinking about how to build a framework for the storage operating system, and I have a lot of thoughts for a while...

①: Snapshot: the image of the corresponding data at a certain point in time (the point in time when the copy starts): save the current image with time as the node, such as taking pictures, which can be used for state backtracking.

======
PS: It’s not that I don’t want to code, but I don’t have time. Writing is very contradictory. If the grades are not good and you update more, you may get good grades, but if you don’t get good grades, it’s hard to eat. Naturally, you have to find another way. It's still my own problem.

The second change is still in conception, and I haven't written yet...
