Siheyuan: I eat melons while doing scientific research

Chapter 1164 POSIL?

This really took up most of Gao Zhendong's energy, and the key was that the progress was slow and work had to be stopped frequently due to waiting for materials.

The materials here refer to the development basis provided by Gao Zhendong.

After typing a few words, Gao Zhendong, who had been troubled recently, patted his head and thought, this can't be done like this, it will delay things, he has to think of a way.

We also need to work out standards for a multi-user network operating system. I originally wanted to let the comrades take on more work, but now it seems that the conditions are not yet mature. This thing is too new for the comrades, and many things are not even taken into consideration.

This often results in that when the development materials made by comrades are sent to Gao Zhendong, Gao Zhendong will make drastic modifications to them. After the modifications, he looks back and realizes that more than half of the materials have been modified. Considering the time spent, it would be better to do it himself.

The main reason for this phenomenon is that Gao Zhendong himself has a set of established, excellent, and mature impressions and solutions in his mind, so when his comrades send him immature things, they will inevitably undergo major surgery.

Chief Engineer Chi from the Computing Institute once joked that other comrades still couldn't keep up with Chief Engineer Gao. This was half a joke and half a fact. In this regard, Chief Engineer Chi and his colleagues were very convinced. Chief Engineer Gao's revisions were indeed good, which made them feel a little guilty. Not only did they fail to reduce Gao Zhendong's workload, but they made it more troublesome.

Researchers all know that sometimes creating something new is easier than making revisions. This feeling is especially strong when they see the results of Gao Zhendong's revisions.

Gao Zhendong thought about it and decided to just use cheats... No, use the big one!

It may be much more effective to first give comrades a basic mature framework and then let them digest and learn on the basis of this framework.

System, start~~~~~~
He had seen the things he was looking for in his previous life and saved them. Although he might not be able to get them directly through the lottery, it would not cost much to search for them specifically.

It can be said that almost everyone who is interested in operating systems has a copy of this, even those who are working on the extremely hard Win. As a relatively good hamster-like information technology student, Gao Zhendong naturally has one.

Found it! Gao Zhendong stood up and walked towards his office at Beijing University of Technology.

The Defense Committee and the troops have invested a lot of money in this classroom. There is an obvious example: there are cameras installed in this classroom! Even if you take things out of the system under cover, there are still certain risks.

Gao Zhendong came to his office, turned on the computer, and took out a set of system-generated floppy disks from the storage library.

He inserted the first floppy disk into the drive and opened it skillfully.

——POSIX 1.0

The full name is Portable Operating System Interface for Unix, Unix-like portable operating system interface.

This is a set of interfaces that define an operating system that is compatible with Unix, including C interface, standard library, shell and command interpreter, file system interaction, process management, information query, network, etc.

This thing was originally created to unify and maintain the compatibility of Unix-like operating systems with Unix. Simply put, your internal source code implementation can be varied, but the full set of interface calls in the operating system must comply with POSIX regulations. In this way, the compatibility and portability issues of the operating system and the applications used can be well solved.

Although this thing was launched to solve compatibility issues, in fact it almost describes the structure and interface of Unix and is a de facto operating system framework standard.

It can be said that this thing is the skeleton of the Unix operating system.

The operating system core developed by Gao Zhendong originally came from the book "Deep Understanding of the Linux Kernel" that he had drawn, and Linux is POSIX-compliant. It can be said that the two are two sides of the same coin.

However, unlike "In-depth Understanding of the Linux Kernel", POSIX is more standardized and more conducive to describing the development elements of a new operating system.

So for Gao Zhendong, it is very easy to use POSIX to describe the multi-user network operating system currently under development. The changes are not large. Of course, the first thing to be changed is the name. It can no longer be called POSIX. At most, it can only be called POSI. It has to be changed to for Unix.

POSIL (Portable Operating System Interface for Loong)? This seems to be a good name! Gao Zhendong thought happily.

With this set of interfaces, Gao Zhendong's work in this area became much easier. The comrades' work on the core of the operating system mainly consisted of filling in codes into the interfaces.

Gao Zhendong started his "hard" work on the computer, mainly doing modification and matching. It was not a lot, but not a little either.

Just as Gao Zhendong was immersed in this simple and unpretentious work day by day, a phone call came to him.

"There's something I'd like to hear your opinion on. You don't have to come over, just talk on the phone." It was the chief engineer of the Defense Work Committee.

Gao Zhendong is currently at the Third Factory, and the telephone line at the Third Factory is of the highest confidentiality level. In other words, all the telephone lines related to Gao Zhendong's work locations and home are of this level. This makes it much more convenient for Gao Zhendong, as he doesn't have to go there in person for some unimportant matters.

"Okay, what is it?"

"A friendly country wants to buy a batch of weapons from us. What do you think about this?" Or something like this, such as equipment export.

"How friendly?" Gao Zhendong asked with a smile.

"Well... those who can buy weapons from us are all very friendly..." The chief engineer laughed and added: "Let me be frank. You have nothing to hide. The Red Sea and Pharaoh's country."

When Gao Zhendong heard it, he was surprised.
The Pharaoh Empire, like us, is one of the four ancient civilizations, but in modern times, while we are constantly becoming more civilized, they have always been not that good.

It was just that this stage was the highlight moment of the Pharaoh Kingdom, which had a lot of good cards. However, as it developed later, the evaluation was roughly the same as that of Dayi by the domestic Internet decades later.

——He is a bad guy who talks harshly but is actually a coward.

It is also a typical case of someone with a lot of good cards but a big loss. Of course, this is a long story and people today don’t know it.

To be honest, this time in 63 was exactly the highlight moment of the Pharaoh Empire's development trajectory. It was on the eve of its decline and was in the midst of prosperity and prosperity.

Thanks to its own efforts and willingness to sacrifice in the Red Sea Canal incident, and thanks to the Citizens' demolition of John of Gaul's colonial system, the Pharaoh Empire prospered a lot. At the same time, it also established connections with the north. It was like having two major empires serving me, which was a great blessing.

At the same time, many nations came to pay tribute to the small circle, and many countries submitted to it, making it the most powerful circle at the time.

Then, in 1967, it had a big one, then it struggled and bounced around a bit, then in 1973, it showed up in a big way but quickly had another big one, then it lost all its spirit, made peace with its old enemy, lost its position as leader of the circle, and never bounced around again.

But speaking of friendship, from a national level, the Pharaohs and we have always been friendly. They went to the north to buy weapons, and it was rumored that we introduced them, because we didn't have many good goods in 55.

After we fell out with the North, it was said that they also had a channel to obtain weapon samples from the North.

In the following decades, Pharaoh has always been our traditional customer for equipment exports, both for the Air Force and Navy.

When Gao Zhendong traveled through time, it was rumored that they were going to buy Shi Ye, who was "the youngest at home and a sad and fierce one when he went out". It was probably the time when Shi Ye played "A bosom friend a thousand miles away" that gave them more confidence.

Gao Zhendong thought about it and thought that this was easy to say. It was indeed a friendly country: "Just compare it to Pakistan."

Pakistan has released both the Lien Chan-7 and the Raiden-1, but has not sold the Raiden-3.

"They want to be first -62."

"Zhengxian-62... I think Zhengxian No. 62 is more appropriate. Zhengxian- is too easy to come by and I won't cherish it, hehe. And..."

The Zhengxian No. 1967 was more advanced than the Styx they used to attack Eilat in . It was just that their anti-ship missiles were the first to kill us, so Gao Zhendong felt that he should compensate them a little.

"And what?" The chief engineer knew that the biggest reason they wanted to buy the Zhengxian-62 was the battle results. From the southern waters to the eastern waters, the Zhengxian-62 was extremely powerful. It would be a lie to say that the Pharaoh Kingdom did not see it. Otherwise, wouldn't it be better for them to just buy the Russian Styx?

Gao Zhendong originally wanted to say that their biggest problem was that the command of the troops was not in the hands of their chief, and that the commander was simply a coward with extremely poor psychological quality. However, this question seemed inappropriate for him to talk about, as it was a bit sensitive, so he changed the subject.

"Our Zhengxian No. 1 is more advanced than the Minghe in the north. The first kill of the anti-ship missile was also achieved by Zhengxian No. 1, which is enough for them. Moreover, their problem is not at sea, but in the air and on land." The first kill of the anti-ship missile by Zhengxian No. 1 made Gao Zhendong's words very convincing.

"Aerial and land?"

"Yes, apart from blocking the Dilang Strait, they don't have much significance at sea for the time being. Moreover, the size and power of the Zhengxian No. 1 are more suitable for attacking large ships. It is better than the Zhengxian No. 1 in blocking the strait trade routes. On the contrary, they have bigger problems in the air and on land, which determine their victory or defeat." Gao Zhendong was really prepared to give some advice.

Blocking the Dilang Strait can strangle the lifeline of their enemies. In fact, the Zhengxian No. 500 can do this very well. When attacking merchant ships, the 62kg warhead of the Zhengxian No. is stronger than that of the Zhengxian-. Da Yi and Xiao Yi should have a lot of experience in this.

"In the air? On land? In the air, they are preparing to buy our planes, and White Bear is also providing planes. On land, their numbers are not small. What's the problem?"
