Operation speed: 50,000 operations per second.
Memory: 72K full word length magnetic core body, a magnetic core memory array.
Hardware scale: The entire machine shares 12,200 electron tubes and 80,000 crystal diodes.
With the world's most advanced tube computer in hand, Li Aiguo feels a bit like he is at the forefront of world technology.
This feels very good.
It’s just
If you want to use the 103 tube computer to realize the automation of railway signals, there is still one key factor missing.
That’s the program.
In this era, the program cannot be executed automatically. It all depends on the operator Chen Jing to use her slender hands on the hard buttons to operate at a hand speed of 300APM.
A tube computer is just fine.
But what Li Aiguo is doing is a major undertaking for the whole railway.
In the future, most railways across the country will realize signal automation, a process that requires thousands of electronic tube computers.
At that time, thousands of young girls may be needed to serve as human flesh programmers.
However, the railway runs twenty-four hours a day.
These little girls can only sit in the dark computer room for a long time and continue to input programs.
In such an environment, their youth can only be carved quietly in a dark hut... This situation seems very inhumane.
We Li Aiguo are a good person, so naturally we cannot persecute these young girls.
So what should we do
The operator Chen Jing entered the program, and while the program was executing, she saw Li Aiguo staring at him, and her face suddenly turned red with embarrassment.
This train driver is indeed married, but it’s not like something can’t happen. For example, they can study computers together.
Chen Jing bit her lip and asked, "Driver Li, is the code I entered just now wrong?"
Thinking about the past two days, Chen Jing felt a little incredible.
After the 103 electron tube computer was successfully developed, such valuable scientific research instruments were not placed in the computing laboratory, but were transported to the railway laboratory and became a productivity tool for controlling railway signal output.
Tube computers require operators.
There are five professional operators in the computing institute. When those operators learned that they were leaving the computing institute and going to work in the railway department, they all backed down.
After all, the railway department is still a rough and tumble department in these days. The impression left on people is that of a rough and tumble man with unshaven beard, black body and soot, who likes to swear when he talks.
The Institute of Computing Technology is the most advanced scientific research unit in the country. The researchers wear neat gray tunic suits, are polite when they speak, and are all highly educated.
Only Chen Jing agreed.
She, the operator, was used as a tool by Li Aiguo and was also packaged and taken to the Railway Research Institute.
It was here that Chen Jing discovered that there was also a research institute on the railway, and it was very rich, and the food in the canteen could be eaten with meat!
"That's not true." Li Aiguo watched Chen Jing ponder for a moment and suddenly asked: "Have you ever thought about writing a program that can run automatically in your computing institute?"
"Automatically run a program?" Chen Jing Somewhat confused.
Aren’t all programs entered manually?
Li Aiguo realized his negligence when he saw Chen Jing's appearance.
There are no high-level computer languages in these days. All programs run directly on the bottom layer of the computer, and real-time loops cannot be achieved at all.
"Without guns or artillery, we can't just rely on the enemy to make them! Pry the Japanese railroad tracks to make cannonballs, and scrape saltpeter to make explosives!"
Li Aiguo hummed a popular ditty on the railway and walked out with his hands behind his back. engine room.
Looking at Li Aiguo’s back, Chen Jing always felt that this train driver was a bit weird.
She turned around and began to simulate input by dangling on the joystick. Only in this way could she maintain the input speed.
The emergence of every high-level programming language requires huge manpower and material resources, and it must also adapt to the development of the times and the market.
If you want to independently create a high-level programming language, that is something that a programming master can do.
We, Li Aiguo, are indeed not a great god.
But he calculated that in a few years, a high-level programming language called BCPL would appear in the United States.
BCPL is the famous B language in later generations and is also the basis of C language.
It's not that Li Aiguo doesn't want to use the C language. The key is that it is too complicated and can explode a tube computer when it is run.
The B language is different. It has a simple structure, but can directly manipulate machine characters and can also write games.
Ahem, the game is just incidental. We, Li Aiguo, are here for railway signal automation.
Master Lu said: "If I can see further, it is because I stand on the shoulders of giants."
After Li Aiguo returned to the office, he stood on the heads of giants , and quickly figured out the B language.
Of course, compared with later generations of B language, Li Aiguo felt that some content needed to be changed so that each object in B language had a type and a value.
The type determines the meaning of the operations that can be performed on the value, as well as the amount of storage space occupied by the object.
In this way, B language has changed from a language that can only control the machine to half a C language, with the ability to compile operating systems.
This kind of work is too tedious for one person to do.
Li Aiguo found Zong Xianfeng and Chen Jingcheng.
“Today we are going to study a gadget.”
Li Aiguo talked about the concept and design of B language.
Although computer language is extremely obscure, its foundation is mathematics, and the boss Chen Jianjin quickly understood it.
"Using the interaction of 0 and 1 for calculation is indeed a new calculation idea. Maybe I should find a way."
Li Aiguo quickly interrupted Chen Jingyi: "Brother Chen, now in China Computers are in extremely short supply, so don’t worry about computer science calculations. Your task is to help me come up with this language.”
Just kidding, there is indeed a branch of mathematics that uses computer calculations in later generations.
However, Chen Ziyi wants to become a man who can crack 1+1, so he cannot waste his energy on this.
Zong Xianfeng is an outstanding student majoring in electrical engineering and has a flexible mind.
Li Aiguo is responsible for the overall architecture, Zong Xianfeng is responsible for code compilation, and Chen Ziyi is responsible for mathematical logic.
It only took a few people less than two days to complete the design work of B language.
With computer language, the next step is to train people who can use computer language.
In the computer room.
Chen Jing had just finished working on her hand speed and was rubbing her sore fingers and sucking on her lips.
Ever since she became an operator, her finger joints have been aching, and sometimes the pain makes her unable to sleep.
But for the development of computers, Chen Jing and the operators concealed this situation.
"Team Leader Li, the program has been entered and is running normally!" Seeing Li Aiguo come in, Chen Jing quickly stood up.
"Don't worry, I came to you today to ask you if you want to be a programmer?" Li Aiguo said with a smile.
“Programmer?” Chen Jing looked confused.
“I designed a high-level computer language so that the compiled program can run automatically. The programmer is the person responsible for compiling the program.”
The program runs automatically, which means no manipulation is required Member.
Responsible for compiling programs, which means she will become a programmer.
In just one sentence, Chen Jing experienced the life of ice and fire from unemployment to re-employment. She nodded hurriedly: "Yes, I do!"
The operator needs a good memory. , good logical concepts, Chen Jing is a college graduate, and has strong learning ability. It only took two days to master language B.
Li Aiguo teamed up with Chen Jing and Chen Jingzi to create a program called Pulse Signal.
After the program is run on the machine, it can stably control automatic railway signals and also has a self-test function.
The news reached the Computing Institute, and the director and Professor Xia Zhongsu were instantly shocked.
"What, a program that can run automatically, and this kind of program can also be compiled?"
"A big thing has happened, and a big thing has happened in our computer field again!"
"It's just such a big thing Why does it happen in the railway sector? It shouldn’t be.”
“No matter which department it is, it’s all about building the country. Let’s go and have a look.”
Aware of advanced programming. Regarding the importance of language, the director and Professor Xia Zhongsu prepared to rush to the Railway Research Institute with a group of researchers.
But there were dozens of people, and there were only three cars in the calculation office, which couldn't fit in at all.
In order not to dampen the enthusiasm of the comrades, the director temporarily dispatched a GAZ truck.
A convoy of cars and a GAZ truck left the computing center in a mighty manner.
Professor Lebedev, who was about to leave the Computing Institute, narrowed his eyes slightly when he saw this scene.
He asked the driver to roll down the window and handed a cigarette to the doorman: "Little comrade, where have these comrades from your computing institute gone?"
The guard took the cigarette with a smile and straightened his face: "I should have gone to catch mice."
Two days ago, he reported what he had been asked by Professor Lebedev to the Security Section Chief. He was severely criticized.
And remind him to keep it confidential and be careful when dealing with experts.
Catch mice? So many people driving big trucks to catch rats? I believe you, you big-headed ghost.
Professor Lebedev looked at the doorman and fell into silence.
Professor Lebedev felt that when he visited the flower grower's house this time, the flower growers seemed to have become cunning, and even dared to bully a small guard.
But Professor Lebedev didn’t pay much attention to the doorman.
He felt that he should still find a way to find out what the computing institute was doing.
Seeing that his little brother was about to surpass him, Professor Lebedev, the big brother, felt very uncomfortable.
The other side.
The convoy arrived in front of the Railway Research Institute in a mighty manner.
The security officers at the door were frightened when they saw dozens of people coming into the computing office. They quickly shook the phone and reported it to Liu Guozhang.
"Report to the director, someone is coming to snatch our rat tail!"
Professor Xia heard clearly from the side and hurriedly explained: "We are from the Institute of Computing Technology. You are mistaken."
The security officer looked at Professor Xia and shouted into the microphone: "Report to the director, the people from the computing office are here to snatch our rat tail!"
Professor Xia: "."< br>
When Liu Guozhang received the call from the guard, there was a question mark on his forehead.
"What? Do these computer people really care about the rat tail of our institute?"
Liu Guozhang is not unfounded.
As the elimination of the four prongs reaches its climax, the mice become increasingly difficult to catch, and the competition between units also enters a climax.
The leaders of some units have their brains turned upside down.
If you can’t catch it yourself, you can snatch it from others.
Besides, can snatching a mouse’s tail be called snatching?
Then do active elimination of the four prongs!
They brought comrades from the Security Section and the Armed Forces Department, fully armed, and while the unit next door wasn't paying attention, they rushed into the warehouse of the other party and snatched away the rat's tail.
This incident has made people in the capital panic.
The security officers at the entrance of some units even set up machine guns to protect the rat tail.
Because of Li Aiguo’s rat-sticking board, the Railway Research Institute is a famous rat-tail dealer in the capital, and others have long been jealous.
You should be more cautious at this time.
“Let’s go, let the security officer bring the rifle and come with me to have a look!”
Liu Guozhang came to the gate with a dozen security officers, asked them carefully, and almost laughed out loud.
"Comrade Director, you have brought so many people to our institute. According to the rules, you should say hello on the phone in advance."
"Sorry, Director Liu, I was in a hurry and neglected it. "
Seeing that there were so many people in the Computing Institute and the director was still in a hurry, Liu Guozhang was moved and asked: "What the hell did Li Aiguo do? Is it so important?"
“It’s not Bo, it’s the ㄅㄛ (Bo) language!”
Although Liu Guozhang is considered a semi-technical person, he is still a rough guy in the eyes of the director.
While walking, he was taking a class with Liu Guozhang: "Computer language is a tool for people to communicate with computers."
Seeing Liu Guozhang's confused face, the director felt that domestic computer education had a heavy task. It’s a long way to go.
He sighed and said: "Let's put it this way, with this ㄅㄛ(啵) language, our country can be at the forefront of the world in the field of computers."
"I said so earlier. , isn’t that enough?” Liu Guozhang’s eyes widened.
He doesn’t understand computers, but he understands what it means to be at the forefront of the world. That means glory!
Although I don’t understand how Li Aiguo did it, Li Aiguo is a person on the railway.
Li Aiguo is glorious, which is equal to the glory of the railway, and it is equal to the glory of Liu Guozhang.
"Ahem, Comrade Director, it seems that our railway technology is more complicated than your computer technology."
"How do you say that?"
"You Think about it, what have our train drivers developed?"
Director: "."
He felt as if he was despised by the boss of the railway department.
But the director doesn't care about this at this time.
After he followed Liu Guozhang to the laboratory, he immediately pulled out Li Aiguo, who was conducting a railway signal stability test.
"Comrade Patriot, have you really compiled a complete set of high-level programming languages?"
Looking at the old professor's anxious look, Li Aiguo didn't say much, and just said (啵) The details of the language are revealed.
"What! You have compiled the program and it has been running stably for five days?"
"You have also trained a female programmer?"
Director There is no partiality.
He took Professor Xia to personally test the program compiled by Li Aiguo in the ㄅㄛ language, and after confirming that the program could run automatically, he was completely convinced.
"Is Li Aiguo really just a train driver using the ㄅㄛ language to compile an executable program?"
The director's head was buzzing.
He felt that the Railway Research Institute was more like a place to study computers than a computing institute.
It wasn't until he saw Chen Jing walking out of the computer room wearing a dark gray uniform of the computing institute that he felt relieved.
At least programmers are still from the Computing Institute.
"Comrade Chen Jing, congratulations on becoming the first female programmer in China. You have worked very hard and it’s time to make progress!"
The director had a vague feeling that this guy Li Aiguo The choice of Chen Jing should be in line with the policy of "women hold up half the sky" proposed by her superiors.
At this time, Chen Jing felt that white flour steamed buns fell from the sky.
She had to work on the railway because no one wanted to work on it.
Now I have become the first female programmer, and I will be promoted soon.
The director, Professor Xia Zhongsu and the experts observed the operation of the railway automatic signals and decided to understand the basic knowledge of the ㄅㄛ (bo) language.
Li Aiguo, the first programmer in the flower gardening family, had to take on the role of teacher.
At this time, Chen Jingwen saw that the work was completed, and he was worried that he would always stay in the railway station and eat for nothing, and the impact of not working would be too bad.
He wanted to return to the Institute of Mathematics to continue his previous work.
Li Aiguo called Chen Zijin: "Brother Chen, tomorrow I will give a lecture to some comrades from the Institute of Computing Technology. Are you here to listen?"
"Me?" Chen Zijin Stunned for a moment.
Chen Ziyi thought that Li Aiguo knew that he was interested in computer science and took him with him, so he agreed.
Chen Ziwen didn't see it. Li Aiguo watched him leave with a smile of success on his lips.
As the sun sets and the sky turns dark, every household returns home.
Li Aiguo came up with a high-level language program today, and he was very happy.
Ride a bicycle to the Chaoyang wet market.
I bought five pounds of eggs, two pounds of duck eggs, and a big carp to improve my life.
Pushing the bicycle into the yard.
The third uncle has also just returned from fishing and is picking up small fish.
Look at the big carp hanging on the handlebar of Li Aiguo's car. He blinked his little eyes and bent over to get closer.
“Patriotic, the taste of big fish is not as good as that of small fish.
I will give you three kilograms of small fish in exchange for your three kilograms of big fish.
I’ll eat some How about I let you take advantage?”
The third uncle picked up a bunch of small cat fish.
"Third uncle, I have a high ideological consciousness and never take advantage, so I can't trade with you."
After saying that, Li Aiguo pushed his bicycle and walked away.
The sentence "never take advantage" confused the third uncle.
He stretched out his hand towards Li Aiguo's back, but could not say a word.
"Old lady, I feel like Li Aiguo is scolding me," the third uncle said quietly while looking at the third aunt who was grinding the electric wheel.
The third aunt nodded: "You feel right."
The third uncle: "."
Pushing the bicycle, he followed the residents and greeted them into the middle courtyard. .
Li Aiguo saw Jia Zhang standing by the pool pointing in the direction of the Yi family and cursing something.
From time to time, Auntie poked her head out by the crescent door, but she didn’t dare to come forward.
There was a group of residents watching the fun.
"What's wrong?" Li Aiguo walked to Xu Damao and asked, holding out a cigarette.
Xu Damao took the cigarette and gloated: "Jia Dongxu had an accident in the workshop today. His finger was pinched by the machine and almost broke."
"This has something to do with Yi Zhonghai. What’s the relationship?”
"Jia Zhang saw that Yi Zhonghai visited Jia Dongxu without a gift, and felt that Yi Zhonghai deliberately arranged for Jia Dongxu to do dangerous work and wanted to harm Jia Dongxu."
Xu Damao seemed particularly excited.
After understanding the ins and outs of the matter, Li Aiguo had no interest in continuing to read.
Compared with being a fool in the courtyard, he prefers to spend his time on business.
Jia Zhang cursed for a while, but did not dare to settle the score with Yi Zhonghai, so she could only go home angrily.
Seeing that Mrs. Jia Zhang didn’t knock on the door, the aunt breathed a sigh of relief and ran back home.
"Old man, Jia Dongxu's injury was not caused by you, right?"
Aunt Ma looked at Yi Zhonghai and asked.
Yi Zhonghai looked helpless: "Can you not know what kind of person I am? Although Jia Dongxu is becoming more and more outrageous, he is still my apprentice. Can I be so cruel?"
“Then why was he injured?”
"Then he can only blame himself for being stupid." Yi Zhonghai's tone was cold.
In the past, Jia Dongxu had Yi Zhonghai to help him, and he only had to do light work in the workshop.
Now that the two families have fallen out, Jia Dongxu can only do heavy work in the workshop like other workers.
After figuring out the whole story, Auntie sighed and said, "Old Yi, Dongxu is your apprentice after all. If I can take care of you, I will take more care of you."
Yi Zhonghai was not happy to hear this. Waving his hand, he interrupted the aunt: "When Jia Dongxu betrayed me, he didn't regard me as his master, so why should I regard him as his apprentice. Don't mention these things again in the future."
The aunt saw Yi Zhonghai and became more and more confused. The more excited he became, he was worried that he would have another heart attack, so he quickly got some medicine for him to take.
After taking the medicine, Yi Zhonghai asked: "Old lady, what has Li Aiguo been busy with recently?"
"I saw him come back today, and he brought a big carp with him."
“This thief actually eats fish!”
Yi Zhonghai was just about to curse a few words when he felt his heart pounding.
He quickly took a few deep breaths and felt a little relieved.
Now I can’t even curse.
Yi Zhonghai felt that he was too aggrieved.
Night is approaching.
Every house lights up.
Chen Xueru's promotion has made progress. Comrades in the district talked to her today. If no one objects, it is estimated that she will be promoted to deputy director next month.
Miss Chen seemed very happy and cooked a large table of dishes.
After eating and drinking, Li Aiguo turned on the lamp, sat at the writing desk, picked up a pen and wrote on the manuscript paper.
"ㄅㄛLanguage Tutorial"
The quality of computer language tutorials is of great importance.
To this day, Li Aiguo still remembers the experience of being almost persuaded to quit by a C language textbook when he first came into contact with programming in his previous life.
Later, I read other textbooks and regained my confidence.
Looking back, Li Aiguo feels that the core spirit of that C language textbook is not to let you learn C language, but to prevent you from learning it.
The comrade who wrote the textbook used his whole life to dissuade countless students from the idea of engaging in computer work.
[If you know which C language textbook it is, you can post the answer. Typing on the public screen】
“The principle of ㄅㄛ language tutorial.”
The tip of the pen is placed vertically and horizontally on the white paper, and neat lines of Chinese characters and symbols emerge one after another.
Chen Xueru washed the dishes and chopsticks, and when she saw Li Aiguo starting to work, she poured an enamel jar of tea and brought it over.
"Brother Patriot, what are you writing? Why can't I understand it at all." Chen Xueru looked at the various weird symbols on the paper, and her little head was full of question marks.
Li Aiguo squeezed the pen and replied: "This is Japanese language, a professional teaching material."
"Bah!" Miss Chen muttered, her eyes suddenly widened and her breathing became rapid.
Her mind suddenly went blank, and she stared blankly at the symbols on the paper.
Can Dabo speak out openly? Has it even been written into a special textbook? !
"There are two methods of direct insertion sorting, one is"
At this time, Li Aiguo read out the sorting method being written.
Forget it, I have to do it now.
“Ah!”
Little Chen Niang cried out in pain, almost ashamed and angry!
Li Aiguo was startled, raised his head and looked at Miss Chen, who was so angry that she was about to shed tears, and wondered: "Xueru, what's wrong?"
"What are you doing? You can write such shameless things!" Miss Chen's face turned red at this time.
Just thinking about those words made her feel like her soul was polluted.
"What a shameless thing"
Li Aiguo looked at the symbols on the material paper, and then he understood. He quickly explained: "This is ㄅㄛ language, BO language, which is used on computers. The language used to compile the program is not what you think. ”
Language program on the computer?
Miss Chen also read news about tube computers in the newspaper, but this was the first time she heard that computers require language.
Li Aiguo then explained: "A computer is a machine. We can only make it work by using a language it understands. This language is called computer language."
Miss Chen Only then did he realize that he had made a big mistake.
It turned out to be her who had impure thoughts.
“Yeah, I seemed drunk just now.”
Miss Chen was so panicked at this time that she slipped into bed and pretended to be a little ostrich.
Li Aiguo looked at the squirming quilt, and then at the Bo language on the paper.
“The cold language of Bo cannot bring the joy of playing Bo.”
He stood up and strode over.
The dim light fell on him, casting a huge shadow against the bright red quilt.
The night is quiet.
The night is lively.
