Courtyard light

Chapter 776 Panda Computer
Liu Hai knew that his junior sister had this little hobby, so he gave the commemorative medal to her after he came back.

No one can touch the box containing the commemorative medal, only my junior sister can do so.

"How long will it take before we can see our fighter jets?" After happily putting away the commemorative badge, the junior sister came back and sat next to Liu Hai.

"I'm not sure about that. We are still undergoing ground testing and will have to undergo flight testing after that. If everything goes well, I'm afraid it will take until June or July to finalize the design."

"But if you want to see it, I can take you to see it." Liu Hai replied.

"No, don't break these rules because of me." The junior sister shook her head.

"Well, actually there's nothing much to see in the plane now. It's all yellow. It will look nice after it's painted later." Liu Hai will of course use a modern low-visibility paint job. Liu Hai seriously suspects that our paint jobs looked ugly in history just to make others less vigilant.

But I don’t care. I just take out the equipment one by one.

However, there are some things that make Liu Hai feel troubled, that is the nuclear reactor on the aircraft carrier and the electromagnetic catapult on it.

When Liu Hai traveled through time, the Ford had an electromagnetic catapult, and the Kennedy was said to have one as well, but it did not have one when Liu Hai traveled through time. According to some internal rumors, my country will also have an electromagnetic catapult aircraft carrier in the future.

Liu Hai doesn't know what the difference is between our electromagnetic catapult and Ford's, because he has never come into contact with it in his previous life.

The main reason is that we are afraid that taking out the electromagnetic catapult technology from the Ford will interfere with our own research.

Historically, we have been relatively advanced in laser, electromagnetics, and radar.

The active phased array radar on the back of our naval ships is more advanced than that of the Bald Eagle because our ships were manufactured later.

There is a latecomer advantage.

If the Aegis system was to be built in 1990, it is not known whether active phased array radar could be installed on the ship.

There are many technologies that restrict the development of radar, and the most important one is actually signal processing.

The farther the radar can see and the wider its range, the more information it receives.

Of course, this does not mean that there were no active phased array radars in the 90s, but that they could not be installed on ships.

On the one hand, it is the speed of information processing, and on the other hand, it is energy consumption.

To give a simple example, if we wanted computers in the early 80s to have the same computing power as the smartphone on the aircraft carrier, how much electricity and hardware would be needed?

In 2020, only a small battery of several thousand mAh is needed to support the powerful computing power of the chip.

This is energy consumption. Active phased array radar can see far and wide, but the hardware facilities consume more energy.

"The yellow one looks good too. As long as it's designed by you, it'll look good." The junior sister hugged Liu Hai and leaned her head on Liu Hai's chest and said.

Little Pomegranate glanced at his parents and then continued watching TV. During the holidays, the little guy was completely left alone.

"Yeah." Liu Hai hummed.

"My parents and my younger brother have returned to their hometown. How about we have a reunion dinner together this year?" the junior sister asked again.

Liu Hai nodded: "You two can discuss it."

"Where are we going to eat? At our house or somewhere else?"

"How about we go to the courtyard house in Houhai?" Liu Hai looked at his home and felt something was wrong.

The main reason is that it is too troublesome to clean up at home. And there is another advantage of the courtyard house in Houhai. Everyone there has a yard, so it is convenient to go home after eating.

"Then what to eat?"

"You guys discuss it." Liu Hai didn't make the decision on these things.

"I want to eat fish, I want to eat crabs." Little Pomegranate heard his parents discussing what to eat and shouted quickly.

"Then remember that." Liu Hai nodded.

"I'll go call Sister Xiaoyun." The junior sister got up and went to call Xiaoyun.

"I'm going back to my hometown tomorrow, you can make your own arrangements." Liu Hai will go back to his hometown tomorrow to visit the graves of his adoptive parents.

"We'll go back with you." The junior sister said when she heard this.

"Why don't you go back together during Qingming Festival? It's too much trouble to travel back and forth in this cold winter." Liu Hai said.

"That's fine." The junior sister knew that Liu Hai would have to be invited to dinner by relatives when he went back. You said it would be bad if he didn't eat. Then you said let's go as a family. It would be much better to go back to visit the graves during the Qingming Festival, and the weather wouldn't be cold at that time.

Liu Hai’s main consideration was that his junior sister did not return to her hometown in Shandong this year, so he simply decided not to bring the child back to his hometown.

The next day, Liu Hai returned to his hometown with a car full of things. The next day was Chinese New Year.

When I returned to my hometown, I found out that Wang Hongmei, Liu Chengcai and Li Xuemei had also come back to visit the grave of Liu Chengcai's nominal father and grandfather.

Liu Hai did not force Liu Chengcai to visit the grave of his adoptive parents, because he had enough of them.

"Xiao Hai, come to my house for lunch at noon." Liu Hai had just finished visiting a grave and was stopped by the team leader before he even got home.

"Okay." Liu Hai nodded and said okay.

When he met relatives from the village on the way, they all invited him to their homes for dinner, but Liu Hai declined.

"Uncle." The days are short in winter, so after Liu Hai got home, he packed up his things and drove to the captain's uncle's house.

"These are for your family, and these are for the poor families in the village, and here is the money." Over the years, when Liu Hai was able to do so, he also helped the poor families in the village.

There are always a few families in every village who, either due to bad luck or other problems, always have a hard time living.

Some people suddenly fall ill at home, while others suddenly have an accident at home.

"Okay!" The reason why Liu Hai didn't give it himself was mainly because everyone in the village was related to each other. If we talk about difficulties, each family thinks that they are in difficulty.

Anyway, as long as you feel at ease, you don't need to build up your reputation.

The captain moved the things back home and went to give them to these families in the evening.

"How long will it take you to return to the city?" When the uncle saw that Liu Hai did not bring the children, he guessed that they would not spend the New Year in the village.

"I'll leave in the afternoon. My uncle will help take care of it." Liu Hai's house is powered by a boiler, so there is no way to turn off the fire in winter. Once the fire is turned off, all the water pipes will freeze.

Otherwise, the water will have to be drained out early, so the heating in Liuhai will have to burn all winter every year.

I'm not short of money anyway.

"Okay." The uncle nodded.

Wang Hongmei couldn't go to the city for the New Year because she had a mother-in-law.

Chengcai and Li Xuemei will return to the city tomorrow, so Liu Hai left today.

Liu Hai first came to the Houhai Siheyuan to take a look. The Siheyuan was fully equipped with heating.

I went home after checking that there was no major problem.

The next day, the family moved to the courtyard house in Houhai.

Liu Hai bought an alley directly. There was a police station at both ends of the alley. Liu Hai knew what it was for.

Xiaoyun came with her three children, and Chengcai and Li Xuemei came later.

Although Li Xuemei heard Chengcai say that he had six younger brothers and sisters, after meeting them in person, she felt that six people were still a lot.

I have to say that celebrating the New Year in a courtyard does feel more festive than celebrating it in a building.

Especially the ability to set off firecrackers without restraint.

The New Year’s Eve dinner is hotpot. You can serve whatever you want in front of you, and you can order whatever flavor you want. You can also prepare your favorite dipping sauce.

Liu Hai looked at the whole family and felt very happy. He silently mentioned his parents in his previous life.

"Alas, I was not born in my previous life." Liu Hai sighed in his heart. He didn't know whether his parents would appear in this life because history had changed so much.

It has changed the fate of many people. In history, many educated young people went to the countryside, but now many of them work in factories, and those with poor status work in mines.

Although working in a mine is hard and tiring, it provides food and clothing, and historically it has been a good job.

So Liu Hai was not sure whether his grandparents could get married smoothly, and whether his parents could get married smoothly, because there were too many unexpected things.

"Let it be!" Liu Hai had no way of finding out about these things.

Liu Hai went to work on the fourth day of the Lunar New Year, but he had not finished the work at hand yet, and all the systems of the entire teaching building No. 001 had not been completed yet.

Besides, Teaching Building No. 001 is just a model system engineering project. The real power system, command system and catapult system have to be taken out separately.

"How can I find a way to understand this knowledge point about nuclear reactors?" Liu Hai reported to the factory director's office while thinking about it.

"Xiao Liu, you come to work so early?" Sun Aiguo was a little surprised to see Liu Hai coming to work.

"My comrades are all working overtime, and I feel embarrassed to take a few more days off." Liu Hai laughed.

"Then go get busy."

"Okay, leader."

"Wait, can we make some fighter jets first?"

"Leader, I suggest we follow the procedure." Liu Hai immediately stopped Sun Aiguo's idea.

If I have a plug-in, of course I can succeed. If I set this precedent, will others also mess around?

"That's fine! There's another problem. The Kingdom of Babylon and the Kingdom of Persia want to pay their debts to buy flying motorcycles, but we don't have that much oil right now?"

"Where are the oil fields?" Liu Hai asked about our own.

"Our oil fields are still pumping oil back, but this is not a big deal. After all, we have a lot of workers in the oil fields."

“Why not sell it to others?” Liu Hai thought about it and it made sense. He couldn’t stop the domestic oil industry just because he wanted to buy cheap oil from abroad.

"The higher authorities do have this idea, but will it lead to a drop in oil prices?"

"If it falls, it falls." Liu Hai had an idea. Isn't Fat Bear selling crude oil and natural gas to Western Europe? We can lower the price here.

Make life harder for Fat Bear.

"Anyway, our flying scooters are profitable enough, but I think we can try another approach, which is for us to import oil and then sell various raw materials to the outside world."

"That's fine." Sun Aiguo thought about the profit of the flying scooter and nodded.

"In fact, if oil is cheaper, more people will buy cars. Although we don't make much money from oil, we can make the same profit from making cars." Liu Hai reminded Sun Aiguo again.

"Yeah!" Sun Aiguo nodded.

Liu Hai came out of the factory director's office and went straight to the J-10 aircraft ground testing.

The reason why it is called J-10 is because there are research projects in the two aircraft manufacturing bases in the southwest and northeast, and the projects were approved earlier than Liu Hai.

Liu Hai didn't ask about the progress of their project. He just worked on his own thing.

The ground test did reveal some minor problems, mainly in the control aspect.

This is also why the speed cannot be too fast when starting ground tests, because you don't know if there will be problems with the control system. If there is a problem and the speed is too fast, it will be troublesome if a plane crash occurs.

All problems have analysis reports, then solutions, and finally observation data.

After seeing Liu Hai here, I drove to Fenghuo Technology Company.

"Happy New Year, boss." Ni Nan was already waiting here.

"Thank you for your hard work." Liu Hai went to work today because Ni Nan sent a message that the first personal desktop computer had been tested.

There is a personal computer placed in front of the bangs, and the monitor size is only 9 inches. What does inches mean? Look at your mobile phones, they are a little bit bigger than this.

The monitor is still a big butt, and there is a separate chassis next to it, and there is a cable connecting the chassis and the monitor.

There is a switch on the chassis, and then there is a separate keyboard and mouse.

"How is the input method?" Liu Hai picked up the instruction manual and asked while reading it.

"The Pinyin input method has been completed, and the Wubi input method is still being worked on." Ni Nanhui reported.

"How does it compare to similar products from IBM?" Liu Hai asked again.

"There is not much difference for general personal users, but there is still a difference for professional use. There is no problem at all for normal office use. We have installed an independent power supply and an independent chip heat sink, and our chip consumes less energy." Ni Nan added.

After reading the instruction manual, Liu Hai pressed the power button.

"Our operating system and pinyin input method take up a lot of memory, so our computers have more memory. Of course, we still make a lot of profit by selling at the same price as in the West. After all, our production costs are low," Ni Nan explained.

"However, our various parts can be assembled by ourselves, so buyers can assemble it according to their own preferences." Ni Nan said proudly, this is also the biggest advantage of this computer.

Liu Hai waited for 10 seconds before the computer started up. After it started up, a screen was displayed, with a panda cartoon background and a progress bar.

I waited for about ten seconds and then a graphical interface appeared with five software programs, all of which were office software, including word processing, data processing, etc.

The resolution of these five software icons looks quite rough.

"Boss..." Liu Hai opened the notepad and was about to type when Ni Nan reminded him.

Liu Hai then remembered that there was no network transmission at present, so after writing these things, they had to be saved on a floppy disk before they could be taken to other computers.

"How is the development of the local area network going?"

"It's in progress. The main issue is the information exchange protocol and speed between them. For now, it's more convenient to use floppy disks." Ni Nan said.

"It's a pain in the ass!" Liu Hai felt it was a pain in the ass when he opened the Pinyin input method, because if he wanted to find a word, he had to select it from the menu, which was not as fast as the smart input method that came later.

But there is no way now, after all, the current input method is so small, and the smart input method will be so big later.

"For this input method, for example, if I selected this word last time, then next time I type the pinyin, it will display this word first instead of asking me to search again. Is it possible?" Liu Hai quickly put forward his opinion without saying much nonsense to the technical talent.

"It's not a big problem." Ni Nan understood what Liu Hai meant and nodded.

"This operating system needs to be further optimized." Liu Hai closed Notepad and opened other office software. The response speed was a little slow. Liu Hai was more accustomed to the method of directly clicking on icons with the mouse.
