"I want to be Zhao Yun!"

"Zhao Yun is a man, Sister Xiaoya, you are a woman, you can only be Liu Bei's wife."

"Zhao Yun can be both men and women, because he has no beard, only a big beard like Zhang Fei wants to be a man, so I can be Zhao Yun. You go to be Zhang Fei, and Jinyan will be Zhuge Liang."

"Oh well……"

Du Qiu and Wang Changan stood on the balcony, chatting in the sun while watching Wang Xiaoya play the Three Kingdoms game with Wang Guanjun and Lin Jinyan. The CCTV version of "Romance of the Three Kingdoms" in 1994 became popular all over the country. Even a few children aged a few years old knew some allusions. In addition, Lin Jinyan also had comic strips, the three children ran around in the living room with various plastic toys, having fun.

"Du Qiu, our company has a designated four-star hotel in Pujiang. The environment and conditions are good. I have booked three of the best suites. I will just go and stay there."

"Please trouble Brother Wang."

"Nothing hassle, just a phone call. Speaking of which, I have to thank you for your strong support this time and are willing to take me to Pujiang."

"There is nothing to support this kind of thing. There is a lot of money in the futures market. One person can't make it all. It's better to have fun alone than to have fun. If you have money, you can make money together and pay together."

"Haha, no matter how much money is, someone must find it out, otherwise the opportunity will slip away in vain."

As the two were talking, Lin Dawei opened the security door and walked in from outside, and went to the balcony and said to Du Qiu: "I have agreed to use Accord as collateral and borrowed 75,000 yuan from Wang Yong. I will transfer the money to you tomorrow morning and pay him 80,000 yuan with the principal and interest next month. If the principal is not returned, the car will be his and the interest will be given."

"The interest rate of 5,000 yuan is nothing. I made it back soon anyway, but it's a bit of a loss after only mortgaged 75,000 yuan. Dawei, your car is well maintained. It's fine to clean up the appearance and sell it in the second-hand market for 100,000 yuan."

"Isn't this a hurry to use it?" Lin Dawei waved his hand and refused to dismiss the cigarette handed over by Wang Changan and said, "Aqiu, if you really make a lot of money this time, I will pay the principal and interest of 80,000 yuan, and then you give me the Accord. I have been driving this car for several years and have feelings for it."

On the afternoon of February 17, when Du Qiu was fiddling with fonts in Yunda's rental house, Lin Dawei and Du Chunhua completed the divorce procedures with a quick knife. However, they were worried that gossip would have a bad impact on Lin Jinyan, so they did not announce it to the public. Lin Dawei came every day during the day and at night, like an ant moving, and only brought a little something out at a time, so the neighbors didn't know about the divorce, only Wang Changan, a close friend, knew about it. Therefore, he seemed a little uncomfortable when he heard this and took a deep breath of cigarettes.

"Cars are a trivial matter, let's talk about it later." Du Qiu was more at ease with his father's funds, not very at ease with Wang Changan, and warned seriously: "Brother Wang, speculation is a heartbeat, and he is willing to accept the loss. You can participate, but don't embezzle public funds, otherwise I will never dare to take you to Pujiang, because even if you make money this time, it will harm you."

Wang Changan smiled awkwardly, patted his chest and promised: "Du Qiu, don't worry, all the money I brought this time was borrowed from relatives and friends, and no cent was public funds!"

Lin Dawei rescued him and interrupted: "The weather is good today, the sun is very strong, and there is no wind. Chang'an and I took these three little guys to Yuhe Park to have fun, and we will treat them to KFC tonight and send them back at around 7 or 8 o'clock."

"OK."

After several children were taken away, the lively room immediately became deserted, which made Du Qiu's ears less noise. He walked into the study, closed the door, then took out a key, opened the drawer under the bookcase, took out the laptop from it, connected it to the desktop computer on the desk, and began to continue studying the browser.

Du Chunhua showed a superior design awareness and business sense at the beginning of her term. Not only did she greatly increase her confidence in the three partners, but Du Qiu was also relieved. So she became a hand-off manager, returned the house rented by Yunda, moved the computer back home, and worked directly in the study. Her mother had an independent personality and focused on privacy. She was a very principled person. As long as she said it in advance and got the key to the drawer, she didn't have to worry about her raid, let alone her circumvention.

Du Qiu told Chen Dayou that he would write a beta version of the browser a month, but it didn't take that long. He had Netscape-Navigator as a model, and two open source browsers, Firefox and Chromium, as a reference. Especially Firefox, which was originally derived from Netscape-Navigator in 1998. Although the code has been unrecognizable after more than ten years of evolution, there are still many ideas for reference, and it is not difficult to write at all. If it weren't for solving the problem of JavaScript, it would be done in a week.

The JavaScript language itself is not a problem, because there are complete documents and related materials in the hard disk, so you don’t need to use your brain at all. You only need to modify it to release it. The problem is that Du Qiu built a building from scratch. The language is only equivalent to drawings. If you want to build a building, you have to solve supporting materials such as steel bars, glass, and cement. In other words, he needs to write a bunch of tools that implement the JavaScript language, such as compilers, debugging tools, and virtual machines. Among them, the compiler and debugging tools are relatively simple, and there are ready-made open source software to refer to. The trouble is the virtual machine, which is the so-called JavaScript engine.

In 2016, the core of a browser must include two engines, one is the graphics engine and the other is the JavaScript engine. Only by combining the two can the content on the web page be fully displayed. In 1995, the HTML language had only one draft, and there was no unified standard. CSS had only one prototype. It has not been popularized in the industry. Both functions and performance are very weak, so the graphics engine is relatively simple, following Netscape of Netscape

-Navigator is enough to imitate it, while JavaScript is 100% "original". Things that have never been before were not found before. In 1995, the 2016 web pages stored in the laptop were too advanced. In addition, the hardware configuration and network environment of the two eras were very different. Neither Chromium's V8 or Firefox's Rhino could be copied, so Du Qiu could only do it himself and explore it slowly.

In fact, Brandon Ike designed the JavaScript language in 10 days, and Netscape spent 7 months to debug it. It was not released until the end of December 1995. At that time, it only embedded a simple JavaScript interpreter in the browser, which was not a real engine, so Du Qiu wanted to create a JavaScript engine in one month, and it was quite stressful.

Of course, he can also lower the standards and make a JavaScript interpreter perfunctory, but that would be too expensive. You should know that the JavaScript language originally designed by Brandon Ike was very rough and had many flaws and shortcomings. Therefore, the initial standard changed almost every year. It was not until 1999 that ECMAScript 3.0 was released, and it was truly mature and stable. It has been used for 10 years and was replaced by version 5.0 in 2009. 5.0 is actually just a minor repair of 3.0. The original version number was 3.1, because the 4.0 version standard was too controversial and was directly abolished. In order to appease the restless minds of commercial companies and developers, the technical committee released 3.1 as 5.0. After another 6 years, it was replaced with 6.0 in 2015...

As a time travel party, Du Qiu would definitely give up the initial immature version and directly release his own JavaScript based on the ECMAScript 5.0 standard. He designed a programming language that has no need to be modified or upgraded for 20 years. It is equivalent to writing a book "Nine Yang Divine Arts" as soon as he debuted. It is a complete martial arts master style. If you only write an interpreter instead of an engine, it is equivalent to fighting a set of turtle punches with extremely low technical content as a master. It is really unreasonable.

When he is focused on doing things, he always ignores the passage of time. Du Qiu is busy in front of the computer, and several hours have passed without realizing it. Until he heard the sound of the door opening outside, he realized that it was almost six o'clock, so he put away his laptop, stuffed it into a drawer and locked it. When he walked out of the study, he saw that it was Du Chunhua who was back.

"What about you?"

"My brother-in-law took him to the park to play and eat outside at night." Du Qiu asked while going to the kitchen to prepare for cooking: "How is the talk with the printing factory?"

"It's all your fault that you offended Wenxiu's father last time. Today I let me eat a lot and I tried my best to negotiate the conditions." Du Chunhua was very upset by his way of dealing with Ma Xiaoli last time. He patted the dining table and taught a lesson: "You are so brave that you dare to hit your wife in the face in front of your father-in-law, husband, brother-in-law and sister-in-law. You are really lawless! Fortunately, the Su family is well-educated. If we change our hometown, you will be beaten to death on the spot!"

"Wenxiu told you?"

"What do you say?!"

This is the first time Du Qiu saw his mother getting angry after traveling through time, but this matter is a matter of attitude towards people's behavior, not a question of right or wrong, and there is no explanation, so he had to remain silent. After teaching a few words of a lesson, Du Chunhua had to sigh and advise, "If you don't want to deal with these troubles, just turn a blind eye or ask someone to deal with it. Don't lose your temper or come forward in person. It's not so easy to be a bird."

"knew."

The kitchen is very spacious, and both of them can cook, and dinner is ready soon. During the meal, Du Qiu took the initiative to report to Du Chunhua about going to Pujiang for financial speculation, because the feelings between people are based on trust. If the trust is gone, there will be cracks in the relationship, and it will be difficult to make up for it. Compared with the cracks, the terrifying nagging is just a passing cloud.

"I wanted to ask you about this. The day before yesterday, you said you wanted to acquire Yunda's printing factory, so you borrowed money everywhere. Today I asked Wenxiu and the others, and they all said that they didn't have this plan, and I knew you were going to do it!" Du Chunhua came out in anger, snapped the chopsticks on the dining table, and said angrily: "Do you take my sister seriously? I said you are not allowed to trade stocks!"

"Sister, don't lose your temper when eating, it's not good for your health." Du Qiu smiled and picked up a piece of fried meat for her and explained: "I'm not going to trade stocks, but to trade treasury bonds. Treasury bonds are guaranteed by the national credit, and they are 100% sure to make a profit without losing money."

"Don't lie with a smile! There is no business in the world that can make a profit without losing money."

On January 17, Du Qiu made an excuse to borrow money, mainly because he just came back from his hometown and could not collect enough information and information to convince his mother. After the buffering of the past two days, he was ready, so he put down his bowls and chopsticks, took out a few sorted newspaper clippings from the study, and analyzed: "Sister, look, this is the treasury bond issued in 1992. According to the regulations at the time of issuance, the sum of principal and interest after the expiration of 100 yuan is 128.5, plus a value preservation allowance of about 20 yuan. When it expires in June this year, it can be exchanged for about 148.5 yuan, right?"

In the 1980s and 1990s, the inflation rate was very high, and it was far better to buy treasury bonds to maintain value when depositing money in a bank. Therefore, almost every household had treasury bonds. Du Chunhua was not unfamiliar with this. After reading the data, he nodded and said, "Unless you bought it when it was issued in 1992, if you buy it now, it will definitely cost about 148 yuan to buy it, and you won't make a lot of money."

"Sister, the value preservation subsidy is adjusted based on the inflation rate. The inflation rate is very high now. Look at the value preservation subsidy rate announced in February is 10.38%. In other words, in addition to the 20 yuan, the country is likely to subsidize another 1 to 2 yuan."

"What you mean is to use 148 yuan to buy treasury bonds now, and then you can make one or two yuan per share after it expires?" Du Chunhuamo calculated, then shook his head and said, "This is indeed no risk, but you can't make a lot of money. Even if you buy 1.48 million yuan to buy 10,000 yuan, you will only make 10,000 or 20,000 yuan, and you don't have 1.48 million yuan at all."

Du Qiu smiled, took out another clipping and said, "Sister, if you buy treasury bonds on the stock exchange, you only need a 2.5% margin. I now have about 300,000 yuan in total, which can be used as 12 million yuan. I can buy 81,000 treasury bonds. If the country subsidizes one dollar more, I can make 80,000 yuan. If the subsidy is 2 yuan, I can make 160,000 yuan. Even if the country does not subsidize, I will not lose money, right?"

When Du Chunhua heard that this was true, he didn't bother to eat. He looked at the clippings several times, and then asked, "Didn't you lie to me?"

"I asked my brother-in-law to consult Sister Jinyu. She said it was fine and she would definitely make a profit. Even their company had prepared millions of funds to enter the market to buy such treasury bonds. She was going to Pujiang with me in a few days."

"Don't go with Jinyu, stay away from her!"

Huh?
