"Snapdragon is really interesting, it actually holds a product launch conference in the cinema, it won't be for us to watch science and education films, right?"
"Who knows, 8 Boss Tianzong is a genius, ordinary people can't guess his thoughts at all, just like last night, who would have thought that he would make up a song in a few minutes? β
"Du Qiu has become completely popular all over the country this time, do you know? When I came here just now, I counted on the newsstand, and there were a total of 13 newspapers reporting on him, except for 5 local newspapers in Sanjiang Province, the rest were all national newspapers. β
"I saw that the reporters from the People's Daily also came, did they report it?"
"No, the People's Daily has always been slow to respond to non-governmental activities, and it is estimated that it will not report until after today's Internet conference. β
The screening hall that can accommodate thousands of people was full, and in the gossip of netizens and reporters, the time unconsciously came to 8:59, all the lights on the roof were extinguished, and the screening room fell into darkness, and after about 30 seconds, the projector rustled, and a mottled countdown appeared on the blank big screen.

"This picture is so familiar, when I was a child, I watched an open-air movie on the threshing floor, and every time I opened, I counted down second by second, for fear of missing one. β
"And I'm looking forward to it, isn't it?"
"That's right, it's the same now, I hope Du Qiu can surprise us again. β
At the end of the countdown, Snapdragon's circular five-color logo appeared on the big screen, the logo rotated like a windmill, shrinking, and after shrinking to the appropriate size, it stopped in the middle of the screen and stood still, and the company's Chinese and English names appeared in a gradual way - Snapdragon Technology Co., Ltd.
The world's first computer-animated feature film "Toy Story" will not be released until November 1995, in August, the vast majority of ordinary people have never seen the animation effect produced by the computer, although the opening animation of Snapdragon is very simple, but the process is very smooth, vivid and three-dimensional, exquisite and fashionable, very cold technology fan, and the traditional hand-drawn animation is very different, so that the audience is refreshing.
When the audience was attracted by the animation effects, Jiang Danfeng, wearing a red T-shirt of the same style but the size that fits last night, walked up to the rostrum from the steps on the left, and said in Chinese and English: "Ladies and gentlemen, welcome to the 1995 Snapdragon Internet product launch." β
"The same T-shirt, last night at the concert waves, but today it is not serious, Jiang Meiren is really a variety of diva, I really want to kiss Fangze. β
"Don't dream, you want money or no money, or you have no talent, what do you use to rob a woman with 8 bosses?"
"Boss 8 has not shown up this morning, it is estimated that he was overconsumed last night, his back hurts and his legs are weak, and he is still resting haha. β
Netizens thought that according to domestic practice, Jiang Danfeng would read a lengthy welcome speech, so they were a little absent-minded and chatted about gossip, but they didn't expect that after she finished her simple and concise opening remarks, she went straight to the point and announced: "First of all, Mr. Du Qiu, CEO of Snapdragon, will introduce the main content of this press conference, please applaud and welcome." β
In the applause, Du Qiu, who was wearing a blue T-shirt, walked up the steps on the right side to the rostrum, and when he took the microphone from Jiang Danfeng's hand, a few good people coaxed like last night: "Kiss one, kiss one!"
Du Qiu turned a deaf ear to this, Jiang Danfeng didn't pay attention to it, and went down the steps on the left side of the big screen silently as when he appeared.
"At the opening ceremony on the morning of August 18, I once compared the current Internet industry to the Age of Discovery in the 16th century, containing countless opportunities to make a fortune, at the press conference on the afternoon of August 18, Yang Fan, chief operating officer of Snapdragon, introduced the specific planning and operation of the Snapdragon Software Park with a pragmatic and efficient attitude......
The film can't be switched or played at will like PPT, so the press conference uses the ancient manual operation, the presenter holds a radio transmitter in his hand, and when he needs to switch the picture, he presses the switch to let the receiving device in the projection room sound and direct the projectionist to play or pause.
The projectionist is a veteran with more than 30 years of work experience, skilled and quick response, after Du Qiu pressed the switch, the projector immediately began to rotate, the logo and company name on the big screen disappeared, and a famous oil painting by the impressionist master Monet appeared "The Sailing Ship of Argenteuil", and several boats with white sails stopped on the calm river bank.
"The Internet is the sea, the software park is the wharf, if you want to go out to sea to make money, there is still a very critical thing, that is, knowledge, for a captain, with the use of sails, charts, compasses and sextant knowledge, you can go to sea, for a netizen, with the use of operating systems, databases, web servers and web design software knowledge, you can start a business. β
Du Qiu pressed the transmitter again, switched to the next picture, and used the most intuitive structural diagram to show the relationship between the four computer technologies, when he explained the structural diagram, Jiang Danfeng took two employees to move a compatible machine to the computer table on the left side of the rostrum, and turned on the screen to the audience after turning it on, and at the same time turned on the camera on the tripod next to him.
At this time, the big screen shows the detailed configuration list of the computer and the corresponding price, Du Qiu introduced: "This is the computer temporarily assembled at the installation competition yesterday afternoon, all the spare parts are old goods purchased from the second-hand market, with a total value of about 8000 yuan, and the operating system has not been installed, and it is in a bare metal state." β
"A few months ago, I registered a www.china.com domain name, named it China.com, but it has not been put into use, in the next time, we will introduce Snapdragon's new products, while installing and debugging on this computer on site, when the press conference is over, this computer will become a server of China.com, officially put into use, you can dial up the Internet to access the Internet on the spot. β
The audience suddenly became interested, many people knew that the distance was too far to see the screen, but they still stood up, stretched their necks to look at the computer, you must know that in the minds of many people in 1995, the Internet server is a very complex and expensive thing, I didn't expect that it only takes a few hours, with a second-hand computer can be done.
If this kind of broken computer can be used as a server, as long as there is a computer and a telephone line at home, anyone can build a website. β
"Those experts from the Chinese Academy of Sciences have not been able to come up with domestic operating systems and database software for more than ten years, and Snapdragon has only been established for a few months, is it possible?"
"It is said that the operating system is tinkered with open-source software from the United States, and there is no technical content, and the database is independently developed by them, but it is very rudimentary, and the function is far inferior to that of foreign manufacturers such as Oracle and Sybase. β
"It's better to be simple than nothing, it's free anyway, just use it, if you can get a great website, you can live a chic life like 8 bosses in the future!"
After Du Qiu completed the opening introduction, he handed over the microphone and remote control to Jiang Danfeng, and walked off the rostrum, Jiang Danfeng said a few witticisms about the lively atmosphere, asked the standing audience to sit down, and then directed the projectionist to project the resumes of James Turver and He Lixing onto the big screen, introducing the positions and work of the two in Snapdragon.
"There are so many Snapdragon talents, even foreigners, and they are top students from prestigious schools. β
"He's a top student, we're not, it's over, I can't understand English at all. β
"Jiang Danfeng should be able to translate, right?"
As a result, netizens guessed wrong, Jiang Danfeng didn't translate at all, and let James explain alone on the rostrum, his speed of speech was very fast, as fast as a Gatling gun, when introducing the history of the BSD operating system, ordinary netizens could also understand a rough idea through the Chinese character annotations and tree diagrams on the big screen, but when he began to explain the various technical points of the Android operating system, the vast majority of netizens were completely blind.
However, not everyone is blind, there are two groups of experts who came to participate in the Internet conference this time, and the experts in the distributed system have left yesterday afternoon, but the experts in the Internet are still in Cloud City, waiting for this product launch, when James introduced the Android operating system to join Snapdragon's original event-driven I/0 multiplexing technology kqueue, he was suddenly amazed and talked about it one after another.
If there is a factory that makes rag dolls, there are 50 workers in it, every time the workers make the dolls, the quality inspectors have to check whether there is a problem, at this time there are two options, one is to hire 50 quality inspectors, arrange one for each worker, so that the inspection is very fast, but the cost is very high, a waste of resources; the other way is to hire only a quality inspector, and wait for the workers who have done the doll to raise their hands and then go to check, this way of taking into account efficiency and cost, in the computer field is called I/ o Multiplexing technology is a very important function of the operating system.
This technology was implemented in the BSD operating system as early as 1983 through the select function, but the select function has many problems, such as poor ease of use, can only listen to 1024 connections at most, and the efficiency will decline linearly with the increase of connections, etc., but the hardware performance was still very backward at that time, the Internet was not developed, and few servers could handle thousands of links, so it was not a big problem.
But by 1995, the hardware performance had increased many times, and the Internet had also risen, and the links to be processed by the server were no longer in thousands, but in tens of thousands or even hundreds of thousands.
In the original time and space, in order to meet the needs of the development of the Internet, in 1997, the Linux operating system launched an improved poll function, and in 2002, the innovative epoll function was launched, which greatly improved the efficiency of I/O multiplexing, and the kqueue function used by Snapdragon was taken out by Du Qiu from the FreeBSD4.0 version after 2000, and Linux is epoll and Microsoft's iocp go hand in hand, and it is the best I/ o One of the multiplexing techniques.
7 years ahead of Linux to come up with new technology, to solve the urgent need for the development of the Internet, if properly promoted, the Android operating system will inevitably be a hit, in the battle for the banner of open source software to seize the opportunity......
