Era: I have a two-world door

Chapter 619, Personal Computer Vision

Chapter 619, Personal Computer Vision
Wang Qingsong returned to the building again, went upstairs directly and went to the mobile phone store.

The mall is not closed yet.

When he arrived, Du Wanting was already sitting in the corner chatting with Du Yunze.

"Brother Du!"

"Axuan!"

Seeing him coming, the two greeted each other.

After sitting down, Du Yunze looked at him and smiled: "Tingting said you have something to talk to me about?"

"Well, something happened!"

After Wang Qingsong finished speaking, he did not rush to speak, but looked at the store and asked: "Is the mobile phone calculator business okay now? If I let you let go, can you pull yourself away?"

Du Yunze was puzzled for a moment.

He looked at his sister, wondering if she wanted to drive him away.

But he still said honestly: "It's okay now. After so much time has passed, the operation has begun to improve. If there is one person in charge, there won't be any big problems with safety."

Wang Qingsong hummed when he heard this.

When the company was first established, there were definitely many loopholes, and the biggest problem with selling mobile phones and calculators was security.

Transportation is an important part of this.

Other than that, it's not that complicated.

She retracted her gaze and asked him, "Brother Du, I heard from Wanting before that you used to work in algorithm development and application at IBM, right?"

"Yes! What's wrong?"

"Do you know programming? Can you tell me how programming languages have developed so far?"

He checked later that algorithm development and application programming languages must be known.

It’s just not the kind of programming language that exists in later generations.

Du Yunze thought about it for a while and said, "How can I put it like this?

Programming languages have gone through several generations. The first generation was machine language, which directly used binary code (0 and 1) to write programs and input them through physical switches or paper tapes. It was highly efficient but almost unreadable.

The second generation is the assembly language that introduces mnemonics (such as ADD, MOV) instead of binary instructions, which need to be converted into machine code by an assembler. The readability is improved, but it still depends on the hardware architecture.
Now it has developed into a high-level language
There are currently three, FORTRAN is the first scientific computing language, supporting mathematical expressions.

COBOL is oriented towards commercial data processing and emphasizes structured syntax.

LISP: The first functional language.

This is what I studied in college, and now I’m focusing on COBOL…”

Wang Qingsong raised his eyebrows when he heard this.

After thinking for a while, he asked, "If I give you a programming language and a compiler, can you work backwards? Also, I want to produce a calculator that doesn't have to be very fast, but has to be small..."

The concept of personal computer was brought forward.

Du Yunze thought for a moment and said, "I'm not sure about this. It depends on the specific situation."

Wang Qingsong saw this and said, "I have something for you to see! But we can't show this to others. We can only study it ourselves."

As he spoke, he handed him a book.

This is the theoretical basis of the C language, which he specially compiled for the mainland. This is more.

Language is not a certain software and there are no patents.

And this will be made public in the future. Anyway, someone will figure it out in a few years. And if a language cannot be popularized, it is not a suitable language.

Otherwise, the equipment produced will not be adaptable.

For the time being, let Du Yunze do the research and set up his own laboratory.

When the time comes, we will arrange people to study from among the recruited college students.

Only when the business is big enough and the talent pool is sufficient can he quickly move the technology of future generations here.

Du Yunze took the thing and looked at it.

Then his eyes lit up, he looked up and asked, "Who invented this?"

Wang Qingsong looked at him and said with a smile: "Don't ask me about this. How about this thing?"

Du Yunze was excited when he heard this.

“Well, this language is really great.

The second generation of assembly language, programs written in assembly language must be translated into machine language that the computer can recognize before they can be executed by the computer.
However, this language is a programming language based on everyday human language. It uses characters that are easy for ordinary people to understand, making it easier for programmers to write programs. It also has high readability, so that people with less computer knowledge can also roughly understand its content.

This is so important to the development of computer programming..."

Wang Qingsong smiled and nodded.

He could understand the general meaning.

It is just like before DOS commands were used to control the use of computers, but now there is a visual window and you can operate it directly with the mouse and keyboard.

The meaning is of course different.

Lowers the threshold for operation.

Then he smiled and said, "You can learn this first, but you can't show this to others for now. There are several more books to come, and I'll give them to you when the time comes. I need your help to develop some things."

Du Yunze looked at the book, put it away and asked, "What are you going to do?"

"I want to build a personal computer, hopefully using desktop analogy and mouse-driven graphical user interface technology."

"What technology is this?"

Du Yunze was confused for a moment.

Wang Qingsong explained briefly: "The mouse is the XY position indicator of the display system... desktop analogy... graphical user interface technology..."

The mouse will be available next year, so he will naturally produce it first.

He has to apply for the patent in advance.

Mosquitoes are meat no matter how small they are.

After listening to this, Du Yunze's eyes lit up.

"What is the principle of the mouse you are talking about? This thing is very important. You know, before, even if you want to simply move the cursor, you must enter keyboard commands.

And the desktop analogy and graphical user interface technology you mentioned are really very useful.”

This thing, like the previous C language, is also an improvement in terms of user experience.

Just move the mouse with your hand to move the cursor to the position you want.

Compared to the previous situation where you had to enter a single line of code, this is quite an improvement.

Wang Qingsong thought for a moment and said, "I will give you these technologies as soon as possible! The prerequisite is that you can study C language thoroughly. You can arrange things here by then! First, vacate a few offices in this building, and buy any equipment you need."

The other party already knows programming languages, so the threshold for re-learning C language will be much easier than that for ordinary people.

I believe that there will be initial results soon.

Of course, this is also relative.

It is impossible to learn everything in three to five days.

Du Yunze agreed after hearing this: "Okay, I promise you!"

Then the baby looked at the thing in his hand.

Wang Qingsong took a look and smiled at Du Wanting, "Then you should cooperate with me. By the way, when you have thoroughly studied it, you can recruit some technicians to develop it together. I will give you some relevant information and key technologies.

Oh, by the way, you can assist Spock when the time comes. The industrial zone may need you to help them design some programs in C language. Of course, the premise is that you also know how to use it. "

The following words were naturally addressed to Du Yunze.

They both agreed with a smile.

Du Wanting then spoke up and said, "Why did you think of doing this again?"

"I am useful! I have popularized small computers to many companies and even individuals."

After hearing what he said, Du Wanting thought for a while.

“I can understand if it can be popularized to enterprises, but I think it’s impossible to popularize it to individuals.”

Wang Qingsong smiled and said, "I know, but the popularization of personal computers in the future is inevitable, just like when televisions first came out, only the rich and powerful could afford them, but with the development of technology, not to mention other places, televisions have already begun to become popular in Japan.

Not only personal computers, but also telephones, in the future every adult will have one.

Of course, this is not something that can be done overnight. It will take some time to develop. All we have to do is be prepared.”

Du Wanting laughed: "How is that possible? TVs are acceptable to every family, but how can everyone use mobile phones, and computers?"

Hearing this, Wang Qingsong just smiled.

If he had not experienced what happened in the afterlife, he might not have believed it.

Don't say anything else.

Nowadays in mainland China, if a family buys a bicycle, it can be something to brag about.

Who could have imagined that in a few decades, the cars that are now only affordable for senior officials will be available in almost every family, or even several.

Not to mention the cell phone. No further explanation.

Since the matter had been settled, Wang Qingsong and Du Wanting left together.

……

The next day, I went to work as usual.

For the next period of time, Wang Qingsong worked in the factory as usual.

The trip with Zhou Ying also ended with leaving Hong Kong Island because the visa period expired.

As for Du Wanting, the production line of circuit boards has been assembled one after another and is officially accepting ordinary workers.

Spock also began to research semiconductor-related technologies based on the information he provided.

As for Hutchison Whampoa, it was also successfully acquired.

……

There was nothing big happening in the department, and I had already made arrangements for my relatives.

Wang Qingsong just went to work in the department as usual.

The long winter slowly passed.

The following spring.

Wang Qingsong was watching the fun there with the people from the factory.

This is the notice issued above.

Pork will be freely available to the public and will no longer require meat coupons.

The only trouble is that you have to queue up to buy meat, and if you go too late there will be no pork.

This made everyone excited for a while.

Can you be unhappy?
Not having money to buy it is one thing, not being able to buy it is another.

At this point, another three years of the three-year difficult period had passed, and for ordinary people, this was truly liberation.

They were all whispering about what to eat tomorrow.

Some people were just bragging, but most people really decided to buy more meat tomorrow and treat themselves.

Wang Qingsong was watching there with a smile.

This year, my salary will be paid according to the conversion from secondary technical school to regular employee, which is 37.5 yuan per month.

Plus Liang Chunxiao’s 28.5 yuan.

There are only three of them, so no one would say anything even if they only ate meat every other day. After all, the three of them are both working.

Of course, Wang Qingsong is not that stupid.

What should be hidden should still be hidden.

Buy some lard, and after boiling it, stir-fry it with lard every time you eat it, and the aroma will come out.

Then eat the meat secretly.

This way, even if it smells like lard, it can be explained as lard, not pork.

"Hey, Qingsong, now it's good, we can finally eat as much meat as we want! We have been so tight on food for several years."

Zhu Yonghua was sighing there.

Upon hearing this, Wang Qingsong nodded in agreement.

Yes, it’s been five years.

Over the past five years, I have eaten less than half a pound of meat per year on average. It is really a torture.

Of course, his family is not included in this scope.

Among my brothers and sisters, the eldest brother has a job. Although it is a bit difficult to support a family of four, he has provided a lot of things in the past two years.

My second brother and his wife are both working, and my second sister-in-law has now resumed work.

It's also very relaxing.

As for the eldest sister, Sun Sanlin now rides a bicycle or a tricycle and has left his job to her.

Although my eldest sister's salary is only 20 yuan, which is equivalent to that of an apprentice, my eldest sister's husband Sun Sanlin earns a lot of money by riding a tricycle every day.

Widow Feng also registered her household registration at Shouhou's home in the name of seeking refuge with her relatives.

It also changed the fate of two people.

They often visit each other during festivals.

Xiaozao is now pregnant and is expected to give birth around June.

Sometimes, pregnancies happen at the same time. My second sister-in-law is pregnant, and my eldest sister is also pregnant.

But it's not surprising. Since they are under 30 years old, it is normal to have another child.

"Hey, Qingsong, have you heard that the higher-ups asked our factory cadres to go to the countryside to find partners?"

The two looked at each other for a while, and Zhu Yonghua looked at Wang Qingsong and asked a question.

Hearing this, Wang Qingsong slowed down his pace.

Nodded gently.

The pilot project has already started in cities, but the scale of the cities is not that large.

The factory also received a notice that it needed to send a number of people to the countryside in batches to live and eat with the local people and get to know the situation.

It's like a secret visit.

It's just that it's already out in the open.

He collected his thoughts and nodded: "Yes, I heard that the factory should send some people over. I heard that the cadres of our factory will take turns to go there. I don't know if it's true."

The newspaper has published it.

But he has never experienced it, so he doesn't know the specific situation.

Zhu Yonghua was muttering: "I don't know the details, but I heard it was quite intense, and those who went there were in danger of their lives!"

Wang Qingsong collected his thoughts and said, "Who knows! If it really is our turn, there is nothing we can do about it."

"It's you, not me! I'm not considered a cadre!"

Zhu Yonghua said with a smile.

These words made Wang Qingsong roll his eyes.

It seems so!
I am a technical secondary school student, which means I am considered a cadre.

I don’t know if I will be sent out.

Collecting their thoughts, the two rushed towards the technical department and met Shu Yang with a drunken mouth on the way!
The two had been enemies before, and they hardly spoke to each other since then.

Zhu Yonghua looked at Shu Yang's back as he left and muttered in a low voice: "This kid is really amazing! He dares to get drunk at work. Does he not need a ticket for this wine? Really, hey, do you know? This kid is now a factory patrol technician. I heard that he is always lazy and often stays in a corner of the factory without working."

Wang Qingsong turned his head and looked.

The technicians who were patrolling the factory were indeed tired, but because they were strolling around the factory, no one knew where they went.

No one can find you even if you hide secretly.

As long as nothing goes wrong, it's no big deal.

Shaking his head, he said, "Don't worry about him. If this continues, something bad will happen sooner or later. Just don't let our technical department be implicated when the time comes!"

Sometimes when something goes wrong in the technical department, it can be a really big deal.

The main issue is safety hazard.

No, just say Cao Cao, and Cao Cao will come.

"Technician Wang, have you seen Technician Shuyang?"

Someone came running over in a hurry.

Wang Qingsong had met the other person, the one from the boiler room.

"What's wrong? He went that way."

"You guys go check it out, the alarm in the boiler room has gone off, go check it out, I'll go find him."

After saying that, he ran away directly.

The two were left looking at each other.

"You go and take a look. I'll go call Section Chief Feng. Please don't let anything happen!"

Zhu Yonghua said worriedly.
