Jiang Danfeng thought that Du Qiu told a good-natured joke when he gave a speech at Berkeley, but in fact, no, the first item he pocketed after arriving in the United States was really FreeBSD, but it was not a CD, but he downloaded the source code directly from the Internet and used it to build the server of the official website of iView. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Choosing FreeBSD instead of Linux to build a server, in addition to the origins before the crossing, Du Qiu also has greater ambitions, that is, like making a browser, first find out the various functions and performance of FreeBSD that was still in infancy in 1995, and then develop a self-contained operating system based on BSD, with the development context of the next 21 years as a reference, and with advanced and necessary technology as a selling point.

1969, AT& amp; Bell Labs, to which T belongs, developed the epoch-making UNIX operating system, and then licensed the source code to academic institutions for research or teaching purposes in a low-cost or even free form, and many institutions expanded and improved on this basis, resulting in a variety of UNIX-like operating systems, the most famous of which is BSD developed by the University of California, Berkeley.

BSD stands for Berkeley-Software-Distribution, and it is very popular because it distributes the source code under a very permissive BSD license, with almost no restrictions except that it cannot be advertised under the developer's name, so it is very popular, and in 1992, a company released an operating system based on BSD, which cost only a fraction of Unix, which attracted at& T was dissatisfied, believing that it infringed on their commercial interests, so they started a copyright lawsuit, and the development of BSD has since come to a standstill.

In the early 90s, personal computers and the Internet developed rapidly, computers using Intel x86 architecture chips swept the world, but the price of DOS and Windows running on it is expensive, many commercial institutions and individual users can not afford it, and urgently need a low-cost or free operating system, BSD was originally a server operating system running on various small computers, and it had begun to transplant to the x86 architecture, but it was interrupted by a copyright lawsuit, Linus, 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 at the right time, in GUN has no operating system core, BSD porting has been shelved, and the Internet explosion has become the climate in just a few years, surpassing BSD and becoming the pearl of open source operating systems.

In 1994, the computer systems research group at the University of California, Berkeley, completed the rewrite, completely removed the source code from AT&T, and the copyright lawsuit was settled, and then released the far-reaching 4.4BSD-lite operating system, which not only derived the direct bloodline such as FreeBSD and OpenBSD, but also used in Apple's OSX and iOS operating systems, as well as Sony's PS3, In PS4 consoles, even Microsoft's Windows operating system references a lot of the TCP/IP network code.

The operating system is the crown of the software industry, if he does not have his own operating system, even if Du Qiu writes countless awesome open source software, he will always stand in the shadow of Linus, he can only be a fierce general, and cannot become a king, so whether it is for ambition or honor, he must have his own operating system.

Apple, which was extremely weak in the 90s, was able to use BSD as the basis for developing OS-X and iOS, and the same can be true for the party, although 1995 was a bit late, and it was difficult to compete with Microsoft, which was about to release Windows 95, in the PC era, but like Apple, it could 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 development team invited him to Seattle to talk, and the other was that the official website of Wired magazine wanted to ask him to help make some iscript animation effects on the homepage.

"Wired magazine is currently the hottest technology magazine in the United States, even President Clinton reads, the official website has more than 3 million subscribers, if you can do special effects on their website, it is equivalent to a free advertisement, which is very good for our iView browser and your iScript. ”

"What about the pay?"

"$15,000 or a free month banner on their website. Chen Dayou pointed to the website on the computer screen and said very angrily: "Although the company's funds are relatively tight now, I think it is better to hang banner ads, and cooperate with special effects, which will definitely attract a large number of users." ”

"Wired" magazine is still a very popular science and technology magazine in 2016, Du Qiu has long heard of it, if it is a paper media advertisement, then it is unwanted, but the website advertising in 1995 is a different matter, he sat in front of the computer and studied for a while, then shook his head and said: "Brother Chen, ask for money, don't want advertising." ”

"Why?"

"First, after they spent $15,000 on special effects, they will definitely remind them on the website to use the iView browser to watch them, otherwise it will be meaningless to flatter the blind. Du Qiu flicked the screen with his fingers and said: "Second, the main function of this website is to scan out the magazines that have been published before and send them to users by email, so there are many subscribers, but there are very few browsing users, only two or three thousand views a day, with 15,000 US dollars, you can go to any website with more than 10,000 daily views to advertise, such as ......"

He paused before saying his name: "Yahoo, for example." ”

Chen Dayou is not a stupid person, but in 1995, few people knew how to advertise on the Internet, so he made a wrong judgment, and immediately understood after being reminded, 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 server for free, but also puts their homepage in the browser's recommendation bar, should we do the same?"

"Don't. ”

Just kidding, this kind of death behavior of marrying others cannot be done by beating to death......

Netscape promoted Yahoo, died by itself, Yahoo became bigger, and then Yahoo promoted Google, and it was empty, Google became bigger, and lost watermelons and picked up sesame seeds, which is the most talked about joke in the IT industry......

Du Qiu advocated the browser business to Chen Dayou, saying that he could make a lot of money with advertising after there were more users, but in fact, he only said half of the words, and the other half did not say, that is, the browser must cooperate with the search engine in order to really make a lot of money, otherwise it can only make a small profit.

Baidu has a search engine, but it doesn't have a strong browser, and it's the weakest of the BAT triumvirate, so don't be cheeky and have to engage the whole family bucket to promote the browser......

Microsoft has an Internet Explorer, but it doesn't have a strong search engine, and it is losing ground under Google's offensive, so it is desperate to burn money and do Bing......

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

The browser has been released in the form of open source, and in the future, millions of programmers around the world will work for free, and you only need to organize the elite among them 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 act, because search engines do not have copyright protection like software, once the pagerank and other link analysis technology is out, it will soon attract many followers and imitators, when the time comes, it is money and marketing, and the technology itself is not so important, and now the capital is too small, and it is easy to be drowned by competitors with funds.

"Nowadays, there are too many websites, and the names are difficult to remember, and without 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, and Chen Dayou pointed at her and asked, "Jiang Meinu, what are you doing with iview when you have nothing to do these days?"

"I didn't do anything, I just used Yahoo to look around. ”

Chen Dayou made an unspoken expression, Du Qiu smiled, and proposed: "Yahoo relies on manual retrieval to do website navigation, and the domestic labor cost is very low, so we can also do the same and make our own navigation website." ”

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

Du Qiu stood up from the computer chair, patted him on the shoulder, and said: "When I visited Stanford a few days ago, I heard two rumors, one said that Netscape was willing to buy Yahoo for 3 million shares, and the other said that AOL planned to buy Yahoo for $3 million. ”

Chen Dayou's eyes immediately lit up.
