Jiang Danfeng thought Du Qiu said a kind joke when he was giving a speech at Berkeley, but in fact, it was not. The first item he took after he arrived in the United States was really FreeBSD, but it was not a CD, but directly downloaded the source code from the Internet to build the server of the official iView website.

In addition to the origins before traveling through time, Du Qiu has greater ambitions, which is to first understand the various functions and performances of FreeBSD, which was still in childhood in 1995 in 1995, and then use BSD as a basis, with the development context in the next 21 years as a reference, and with advanced and necessary technologies as a selling point, he will create his own operating system.

In 1969, Bell Laboratory, which belongs to AT&T, developed an epoch-making Unix operating system, and then authorized the source code to academic institutions for research or teaching in a low-cost or even free form. Many institutions expanded and improved on this basis, forming a variety of Unix-like operating systems, the most famous of which is BSD developed by the University of California, Berkeley.

The full name of BSD is Berkeley-Software-Distribution. It publishes source code under a very loose BSD license. It has almost no restrictions except that it cannot advertise with the developer's name, so it is very popular. In 1992, a company released an operating system based on BSD, which was only one-quarter of that of Unix. As a result, it attracted dissatisfaction from AT&revealed its copyright lawsuit, and the development of BSD fell into a stagnation since then.

In the early 1990s, personal computers and the Internet developed rapidly. Computers using Intel X86 architecture chips were popular all over the world. However, DOS and Windows running on them were expensive and could not afford them. Many commercial institutions and individual users could not afford them. They urgently needed a low-priced or free operating system. BSD was originally a server operating system running on various small machines. At that time, it had begun to transplant the X86 architecture, but was interrupted by a copyright lawsuit. Linas, who was studying at the University of Helsinki in Finland, had no choice but to develop a new operating system and named it Linux.

The so-called times create heroes. Linux is just at the right time. With the three major advantages of GUN without an operating system, BSD transplantation is shelved, and the Internet outbreak, it has become a climate in just a few years, surpassing BSD and becoming the top actress in open source operating systems.

The computer system research team at the University of California, Berkeley completed the rewrite work in 1994, completely removed the source code from AT&amp

The operating system is the crown of the software industry. Without his own operating system, even if Du Qiu wrote countless awesome open source software, he would always stand in the shadow of Linus and could only be a powerful general and could not become a king. So whether it is for ambition or honor, he must have his own operating system.

The extremely weak Apple in the 1990s could develop OS-X and IOS based on BSD, and the time travel party was also OK. Although it was a bit late in 1995 and it was difficult to compete with Microsoft, which was about to release Windows 95 in the PC era, it could, like Apple, stick to certain professional fields, accumulate development experience and technical strength, and prepare for the smartphone era.

When Du Qiu returned to San Jose from Berkeley, Chen Dayou reported two good news. One was that Microsoft's browser research and development team invited him to Seattle to talk, and the other was that the official website of Wired magazine wanted to entrust him to help make several iScript animation effects on the homepage.

"Wiang is the most popular technology magazine in the United States. Even President Clinton reads it. The official website has more than 3 million subscribers. If you can do special effects on their website, it is equivalent to making a free advertisement, which is very beneficial to our iView browser and your iScript."

“Where is the reward?”

"Only $15,000 or a free banner ad on their website for one month." Chen Dayou pointed to the website on the computer screen and said proudly: "Although the company is tight now, I think it is better to hang banner ads. Cooperating with special effects will definitely attract a large number of users."

Wired magazine was still a very popular technology magazine in 2016 and has a great influence. Du Qiu has heard of it for a long time. If it is a print media advertisement, it would be undesirable. However, the website advertisement in 1995 was a different matter. He sat in front of the computer for a while, then shook his head and said, "Brother Chen, please don't want advertisements."

"Why?"

"First, after they spent $15,000 to make special effects, they would definitely remind themselves to use the iView browser to view it on the website, otherwise it would be a glimpse of the blind man, which is meaningless." Du Qiu flicked the screen with his finger and said: "Secondly, the main function of this website is to scan the magazines that have been published before and send them to users by email. Therefore, there are many subscribers, but there are very few users who browse, with only two or three thousand views a day. With $15,000, you can advertise on any website with more than ten thousand views a day, such as..."

He paused for a moment before saying the name: "Like Yahoo."

Chen Dayou is not a stupid person, but in 1995, few people knew how to advertise on the Internet, so they made a wrong judgment. After being reminded, they immediately understood, agreed with Du Qiu's choice, and said: "Yahoo is now one of the most popular websites on the Internet. Netscape not only provides a free server, but also places their homepage in the browser's recommendation bar. Should we do this too?"

"don't want."

Just kidding, this kind of act of dying is not allowed to be beaten to death...

Netscape promotes Yahoo, but it dies, Yahoo becomes bigger, and then Yahoo promotes Google, but it is vain, Google becomes bigger, and it loses watermelon and picks up sesame seeds. It is the most talked joke in the IT industry...

Du Qiu advocated the browser business to Chen Dayou, saying that after there are too many users, you can make a lot of money by advertising. In fact, only half of the words were said, but the other half did not say that the browser must cooperate with search engines to truly make big money, otherwise you can only make small profits.

Baidu has a search engine, but does not have a strong browser. It is the weakest among the three BAT giants, so it is shameless to create a family bucket to promote the browser...

Microsoft has IE browser, but does not have a strong search engine. It is defeated by Google's offensive, so it is necessary to make bing even if it is desperately burning money...

Operating system + browser + search engine, this is the skeleton of the Internet empire that Du Qiu wants to mess with, so the company established in Beijing is called Snapdragon Software Company, not Snapdragon Network Company. The programmers recruited by high salaries are proficient in the underlying technologies such as assembly and C language, rather than Internet technology, which is reserved for the operating system plan.

The browser has been released in the form of open source. In the future, millions of programmers around the world work for free. They just need to organize the elites and do a good job of version management, without wasting too much energy.

Search engines are the focus of future work, but Du Qiu is not in a hurry to take action, because search engines do not have copyright protection like software. Once link analysis technologies such as PageRank are developed, they will soon attract many followers and imitators. At that time, they will be competing for money and marketing. The technology itself is not so important. Now the cost is too little and it is easy to be drowned by competitors with funds.

"There are too many websites now and the names are hard to remember. If there is no URL navigation, many people don't know what to do after opening the browser." At this time, Jiang Danfeng happened to come down from the second floor. Chen Dayou pointed at her and asked, "Beauty Jiang, why are you doing with iView when you are fine these days?"

"I didn't do anything, I just use Yahoo to watch it casually."

Chen Dayou spread his hands and shrugged his shoulders, making an self-evident expression. Du Qiu smiled and suggested: "Yahoo relies on manual retrieval to navigate the website. The labor cost in China is very low. We can do this and make our own navigation website."

"No matter how cheap it is, it's still money!"

Du Qiu stood up from the computer chair, patted his shoulder, and said, "When I visited Stanford a few days ago, I heard two rumors. One said Netscape was willing to spend 3 million shares to acquire Yahoo, and the other said that AOL planned to spend $3 million to acquire Yahoo."

Chen Dayou's eyes immediately glowed.
Chapter completed!
