Chapter 144 I am definitely not here to play games! (4k)
Gao Zhendong really took a vacation for himself. He sat in the living room, turned on the TV, put snacks on the table, and opened the door.
Children who were not in school gathered around his house in the yard, chattering and watching TV. There were not many programs on the TV, but they could eat snacks and watch the little people moving around on the TV. The children are already very happy.
The next day was Tuesday, and it was still the front page of that large national daily newspaper.
A report "my country has achieved a breakthrough in the manufacturing of urea steel" appeared on the paper.
In the report, the comrades in my country's steel industry were highly praised for their silent dedication and hard work. After receiving a request for help from the chemical research unit, they quickly organized manpower and allocated resources, worked hard for XX days, and successfully trial-produced my country's first batch of urea industrial steel. , paving the way for the industrial production of urea and contributing to my country's food security construction.
The successful trial production of urea steel has filled a domestic gap and represents a lot more.
The article specifically states that the trial production of urea steel is the result of the concerted efforts of many steel companies, which reflects the superiority of our social family.
In the accompanying picture, although the color cannot be seen in the black and white photo, the big red flower on the top of the urea steel seems to be shining brightly.
However, just like the last report on DJS-59, no name of any member of the scientific research team was specifically mentioned.
Since the leader cannot be mentioned, there is no need to mention the others.
At this time, the comrade in charge of communication with the north received a cross-border call from the north.
Although there are dark clouds in the relationship between the two, the camps are clear and the direction of struggle is the same. International relations will never be a simple child's play house. Hum, I don't want to play with you. It’s time to play.
Same as the 591 superalloy last time, this comrade was happy but cautious when he learned that the north wanted to buy a batch of transistor computers from here.
"Davari, I need to verify your request before I can answer you. You know, your request involves a direction that requires me to confirm more information."
"Okay, my comrade, I'm waiting for your good news."
Hang up the phone, and the comrade in charge of North Korea immediately called the 12th Machinery Department to inquire about the status of the transistor computer.
When I learned that we indeed had a new type of computer, and it was exactly what the comrades from the north had requested, the comrades from the north were a little excited. For him, he was usually the one who made the demands of the north, and there were few This is the first time I have encountered this situation.
After quickly sending someone to obtain the publicly available information about DJS-59, he took the information to the leader in charge.
Seeing that we have another high-tech product that can be exported, the leaders in charge are very happy. Although we still don’t know whether it can be exported, this matter itself represents a meaning.
If Gao Zhendong knew this, he might think that if the north got used to importing some high-tech products from here earlier and could be embarrassed earlier, it might not be so difficult in the future.
Face is harmful, it might be a good thing to get used to it early.
Many things will always be done without opening the door. Once you do it a few times, you will gradually get used to it.
However, the leader in charge also needs to discuss this matter with someone. The sensitivity of computers is much greater than that of alloy materials with a single function.
Perhaps it is because we are not used to exporting high-tech products, so things like the export control list of high-tech products do not exist yet and are discussed on a case-by-case basis.
It seems that this matter will have to wait for the Davari family in the north.
As for Gao Zhendong himself, after finally returning to the No. 3 Steel Rolling Plant, he must first report to his master.
Seeing him, Lao Chen took out a cardboard box from the drawer: "Here, this is your new work permit, please change it."
The gun permit is separate. No need to change.
Gao Zhendong took it over happily. Everything else was basically the same, except that the job title was more complicated.
Position: Director of the Research Office of the Technology Division (Deputy Division Level)
Deputy Section Chief of the Training Section of the Security Division
Professional Title: Engineer (Level 7)
Major: Metallurgy, Automation< br>
Professionally, metallurgy was even before automation, and this was a big deal.
The densely packed characters filled up the small job column. Fortunately, the work certificates of this era had to fill in the details manually. The comrades in the Human Resources Department probably had to put in some effort to fill them in.
Taking back Gao Zhendong's old work permit, Old Chen looked at Gao Zhendong and suddenly said: "Slow down, slow down, you have done enough, take a rest."
Old Chen really felt sorry for this apprentice. Since he entered the factory, he has been working non-stop and has never stopped.
Old Chen didn't know what was driving the young man, making him so urgent that he didn't stop for a moment.
Perhaps it is the love for this country that has gone through hardships and reborn from the ruins, Lao Chen thought.
If Gao Zhendong could know what Lao Chen was thinking, he would definitely think, Master, you are half right, but the other half, I cannot and cannot say.
Gao Zhendong nodded: "Okay, I'll adjust the rhythm."
Although he said this, in fact, it was mainly about what he was doing. What he could see was really all Results cannot be produced immediately.
However, it is slow, but it does not prevent me from continuing to expand my influence at all.
Looking at the several employment certificates and expert certificates in his storage, Gao Zhendong thought happily.
Lao Chen looked at him and smiled: "You must have your own ideas, haha, that's right. Young people, it's a good thing to be motivated. What are your next ideas?"
This is called mouth. No, I was taking it easy just now, so I turned around and asked about work arrangements.
Gao Zhendong thought for a while: "One is to improve computer matters. This thing is very important. Secondly, to finish a few books that have been promised to others. The only ones that can be seen now are these two Things."
When Old Chen heard this, he almost laughed out loud, and then he remembered that his apprentice's major was actually automation.
"Well, that's not bad. There's nothing urgent. I can let you adjust it. The strings are always stretched too tight and will break. I will help you take care of the daily affairs of the laboratory first. You can arrange your time more freely.”
Gao Zhendong was stunned: "Master, this is not good, I still want you to help me with things. Isn't it a bit unqualified to be an apprentice?"
Old Chen laughed: "Haha, everything you do I should do something, but I can’t do it. Then if you help me do it, shouldn’t I do something for you?”
That’s true. Every achievement of Gao Zhendong is what Lao Chen should do in his position, but it was Gao Zhendong who did it.
Thinking about it this way, it’s okay. The master is kind and the disciple is filial.
After saying what needed to be said, Gao Zhendong said goodbye to Lao Chen and walked out.
As soon as I left Lao Chen's office, I met Deputy Director Wu and Deputy Director Zhao, new members of the Technical Department. The positions were new, but the people were old. This reminded Gao Zhendong of a joke he saw in his previous life, a pair of new characters and two old things.
Seeing the two people, Gao Zhendong thought they were here to see Mr. Chen: "The two division chiefs want to see Mr. Chen? He happens to be free now."
The two deputy directors shook their heads: "No, no, director Gao, we are here to wait for you."
"Is something wrong?"
"It's okay, it's just that the technical department has been upgraded. You weren't here at the time, so the two of us thought that when you come back from the expedition, we must invite you to get together. No, as soon as we heard you came back, we came."
Gao Zhendong could probably understand the thoughts of the two deputy directors, and did not refuse. People can be noble, but they cannot be aloof.
"Okay, then noon?"
Deputy Director Zhao shook his head and said: "Noon is not good. If you can't drink, you won't have fun, how about at night?"
Deputy Director Wu nodded: "Yes, yes, afternoon."
Gao Zhendong thought about it and said, "Well, okay, let's meet in the afternoon."
Having already said the greetings that should be said, and met the people who should be met, Gao Zhendong jumped in. into the computer room.
During his time at the Beijing Steel Plant, he had accumulated too much operating system source code, all without debugging.
Although later generations of operating systems are very large, they are actually the result of having a GUI (graphical user interface), maintaining multi-generation compatibility, and maintaining driver compatibility for countless hardware peripherals.
With all this stripped away, it is just a single-channel batch processing operating system under the command line interface. It is actually much simpler. Even process scheduling can be handled in a minimalist way.
Many issues that need to be dealt with and considered in a time-sharing operating system can leave interfaces in this system, but no processing will be done for the time being.
The part that Gao Zhendong has completed now is the hardware driver part.
The reason why it is so fast is inseparable from the simplicity of the hardware.
The keyboard driver has already been written and does not even require much rewriting. Just convert the original code from assembly to C and encapsulate it well.
Encapsulation here and object-oriented encapsulation are two concepts. The C language itself is not object-oriented, C is process-oriented, and C++ is object-oriented.
In the current hardware environment, using object-oriented is undoubtedly causing trouble for yourself. To a certain extent, when the hardware capabilities are limited, Linus's words are absolutely correct.
Technology has never been water without a source or a tree without roots. A good technology cannot be said to be good if it is separated from the environment.
With the computer conditions Gao Zhendong currently has, what he needs is simplicity, flexibility, direct access to the underlying hardware, and maximum direct control of the process and data by programmers.
Instead of wasting precious computer resources on the cumbersome and bloated object-oriented approach.
In order to achieve this goal, it doesn't matter that Gao Zhendong even sacrifices a certain amount of security and procedural rigor.
This difference can be seen from a statement that will rarely be used by future programmers.
The goto statement in C language is an unconditional direct jump statement.
Similar statements often exist in early high-level computer languages, although their use is not recommended for the sake of program readability.
However, this statement is not uncommon when engaging in C language programming, especially embedded programming, because sometimes this thing is really useful when directly facing the bottom layer.
But in later languages such as java and python, this statement does not even exist by default.
Having said that, Gao Zhendong's keyboard driver only needs to be packaged, or packaged.
As for the tape drive driver, Gao Zhendong has retrieved the latest version upgraded by the computing center from the computing center.
Magnetic core memory is readily available as a driver for main memory.
As the four underlying hardware drivers to be implemented first in Gao Zhendong’s plan, the above three had already been solved or solved by hand when he officially started operating the operating system.
For the remaining monitor, Gao Zhendong had to write it himself. There are still too few people in the computing institute who are proficient in the C language, not enough, not enough at all.
Because Gao Zhendong not only had to solve the driver problem of character output, he also wrote a simple graphics driver. By the way, in the C compiler on the upper layer, he implemented the most basic graphics.h header file of C language, converting the basic pixel Functions, straight lines and line functions, polygon functions, and fill functions have all been implemented.
In fact, in the short term, this job is a thankless job. Pure numerical calculations do not require this thing, and the output of various scientific calculation graphics is limited by the XS-59 monitor 320*240 The limited expressive power of resolution.
But Gao Zhendong did it anyway, because he was accustomed to the powerful display capabilities of computers in his previous life. No matter what, he wanted to show the immature graphics capabilities of computers as soon as possible.
Don’t ask, just ask willfully!
He is definitely not here to play games!
After connecting the DJS-59 to the tape memory, Gao Zhendong began to enter the code line by line.
The writing is complete, but debugging still needs to be adjusted bit by bit.
This matter is physical + mental work.
Fortunately, the tape drive driver was debugged by the computer. If this thing is not reliable, then Gao Zhendong will be in real trouble.
I have been busy until I get off work, and the first three items have been completed. However, the display driver debugging has just entered the character output display part, and the trouble is still behind.
Pack your things and get off work! Let’s go have dinner with Old Wu and Old Zhao.
The Third Steel Rolling Plant has no regard for what Gao Zhendong is doing specifically. The management of the daily work of the technical department's research office, if Gao Zhendong is too busy, is under the direct control of Mr. Chen. As for Gao Zhendong himself, Even Lao Chen doesn't care.
Everyone has a consensus: there is no need to go to Gao Zhendong for general matters in the laboratory. Gao Zhendong is very busy and has many things to do.
While Gao Zhendong No. 3 Rolling Mill continued his plans for the operating system and compilation of C language textbooks, in the office of the leader of the National Defense Working Committee, the leader of the National Defense Working Committee held a document in his hand and frowned.
"What did you do? There are good news from 5DL. They have also gathered many factories and military academies. However, a simple armored vehicle is stumbling and has been unable to make a final plan."
"Leader, we were almost done, but as soon as the 592 rolled armor steel came out, we adjusted to use a new steel type. The density of the new steel type is different, and the performance is better, and the required thickness and weight are also different. , the center of gravity of the vehicle changed greatly, and it was delayed.”
