After a full fifteen minutes, Su Xiaomu looked at the blank debugging archive, and the whole person fell into deep thought.

In the past fifteen minutes, Su Xiaomu has only done one thing, to restore the down iMac Pro.

Fortunately, Apple's macOS is not complicated as a whole, and Su Xiaomu is not too difficult to recover from scratch.

As for why Su Xiaomu took fifteen minutes......

Very simple.

There was about eight and a half minutes of time, and Su Xiaomu was thinking about whether it would be useful to restore the state of the operating system to the dead machine by himself.

It's like Schrödinger thinking about his famous superimposed thought experiment about cats.

But if 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, this experiment would be incomplete.

On the other hand, if it was useless to hold on to the end, these fifteen minutes would be enough time to get a new wave of debugging......

"Alas, today is not a good day to do things!"

The right time, the right place and the right people are not there.

Speaking of which, Su Xiaomu also thought about a lot of other things in the past fifteen minutes.

Most of the above can be regarded as an extension of regret.

For example, why don't you take instant snapshots when you are debugging like a normal student? ①

For example, why do you want to provoke the firewall deployed on the supercomputer that you have built yourself when the data is not archived?

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

The only way to do this is to wish yourself a happy April Fool's Day!

Just as he was 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?"

"I can't seem to make it ...... time"

Magnetic hard disks are all rewritable, and when Su Xiaomu tried to restore the system state to the point in time he needed, new data had been generated, and the original data had been logically overwritten.

Not to mention the pristine state.

If you can still think of a way to cover the original data, take the data recovery fee software on the market as an example, it can also support retrieving a lot of data.

But......

Retrieving the status ......

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

The market demand is not large, because when it comes to manipulating important data states, system states, operating states, etc., there is basically a process for setting up automatic snapshots.

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

Others have more complex and adaptable snapshot capabilities.

"Shi Lezhi, if you have this time, it is better to go through the debugging process again, although there will not be the same flowers, but it is also another type of industrial test......" Su Xiaomu comforted himself.

If there is a market for software that recovers the state without snapshot operations, Su Xiaomu is still willing to spend some time tinkering with it, and it is also a money-making thing.

Even if he doesn't understand business or the market, this kind of thing can be handed over to Soho.

After glancing at the time, it was just over 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 something.

Looking at the constantly outputting test results, Su Xiaomu began to beep quietly.

"Probably the best news of the day, 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 becomes clear.

As the core module of the storage operating system, the storage file system is, of course, the same as the underlying file system of Android, embedded in the storage operating system based on the Solaris operating system that has gone bankrupt to run a wave of simulation tests.

There's actually something in there.

Su Xiaomu's initial architecture idea was derived from Solaris's ZFS file system, and from a certain point of view, the Solaris system is storage with ZFS.

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

Therefore, the test 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 intensity of quadrillion tests per second.

While conducting simulation tests, Su Xiaomu also had to find time to improve other core modules according to the file system.

Of course, Su Xiaomu does not plan to make a general-purpose operating system, only for the storage field, and will try his best to cut all the functional modules that are not used to simplify the operating system.

There are many reasons for this, 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 materials that have not been thoroughly digested......

Just as Su Xiaomu was watching the time, it was not too early, and when it was time to settle lunch, Soho's phone dialed in.

The first thing you hear is:

"Su Xiaomu, come out and eat together. ”

Su Xiaomu sighed, "Where is it?" ”

Soho gave an address, "...... Hurry up, it's a foreign festival today. ”

"It's almost twelve o'clock, and the conventional rule is to be a fool before twelve o'clock, you know? Su Xiaomu said casually.

As he spoke, he had already gotten up and was ready to go out.

Su He was choked by Su Xiaomu, so he snorted, "You care about me! I won't follow the convention, what's wrong?"

The phone was all hung up, and Soho was still muttering.

"Oh, man, it's not interesting!"

"Didn't take us to heart at all!" Soho said in an accentuated tone.

Wan Dai on the side nodded, "That's it, don't you know if we're going to be there!"

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

"Hmph, aggrieved, super aggrieved!"

The more Soho and Wan Dai's best friends talked, the more they felt that they were super aggrieved, and their usual shrewdness and ability were thrown away.

They're just ordinary girls now.

Or because of something that has wronged her own girl.

Therefore, Soho and Wan Dai have the same hatred for each sentence to the end, and make up their minds, today's April Fool's Day is decided!

Go to its conventions......

Su Xiaomu didn't expect things to turn out like that later, strictly speaking, it was the first time that Su Xiaomu found out that he was actually in a certain scene, and his temper was not very good.

Of course, Su Xiaomu didn't know these at this time, he didn't forget what Soho had specially reminded him of, Phaeton needed to refuel when he went out.

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

According to the positioning given by Su Ho, Su Xiaomu hurried over.

I was still thinking about how to build the framework of the storage operating system, and I had 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 at which the copy begins): The current image is saved by the time node, such as taking a photo, which can be used for state backtracking.

======

PS: It's not that I don't want to code words but I don't have time, writing is very contradictory, and I may have good grades if I don't have good grades, but it's hard to eat and have to find another way, so I don't have time to code words, so ...... In the end, it's still your own problem.

The second update is still in the process of being conceived and has not yet been written......
