"I'll ask you first, why do you want to learn mathematics?"

The newly established "Zhiyuan College" has a holiday time later than other subjects, and Yang Yi's math class has also been put to the end.

"Mathematics contains truth." A classmate answered.

"It's very good." Yang Yi himself was quite satisfied with this answer, and there was no standard answer to this question.

"What is truth? Truth is a natural law. For example, 11 is equal to 2. No matter where you go, as long as you enter a black hole in this universe, 11 cannot be equal to 3. This is the truth. Learning mathematics is learning laws and understanding these laws.

The original meaning of our Chinese language is to learn expression ability, and the purpose is to learn to speak and write. What is the purpose of learning mathematics? You are all prides of heaven and should have your own answers.

When doing something, you must first recognize your purpose so that you can avoid detours.”

Seeing the students listening carefully with contemplative expressions at this moment, Yang Yi was a little satisfied. Young people rarely listened to these words. "It is undeniable that poetry can also express some things, just as Olympiad problems can also contain some mathematical rules, but poetry is more infecting people's emotions through rhythm and format, just like people sing. The lyrics written by people in ancient times were actually poems used to sing, both music and rhythm.

Solving Olympiad problems is like writing poetry, but writing good poems does not mean that you understand a lot of truths, and solving Olympiad problems does not mean that you can’t represent mathematical ability. Nowadays, many new students have this problem. Many people desperately solve arcane problems in high school, just like literati in ancient times wrote poetry when they had nothing to do. No matter how good the poems were written, they were just for a quick moment. The real truth was still in those mathematical formulas..."

Yang Yi also recommended some books on studying mathematics and listed some book lists. The holiday time cannot allow students to be free. Students who are qualified to choose to enter "Zhiyuan College" are all smart and have their own plans for the future. Yang Yi cannot let them down!

The topics set up cannot be relaxed. Whether it is for industrial upgrading or screening assistants, they have to work harder to learn mathematics.

Mathematics is a discipline that studies concepts such as quantity, structure, change, space and information. In the development of human history and social life, mathematics also plays an irreplaceable role and is also an indispensable basic tool for learning and studying modern science and technology.

After finishing the school affairs, Yang Yi knew that he might have less and less time in school, and he might not be in school in the next school year. With the help of the school platform, many of Yang Yi's achievements were produced in the school's laboratories, and of course they also left a lot of results for the school. However, a lot of papers were published, and some basic patents were even made public, especially biological patents!

Some patents in biology are also authorized, and Starry Sky Group's current assets can only ensure investment in information industry technology.

The investment in each industry is very huge. Even if you can produce top technology, the upgrading of related industries is very slow. For example, CNC machine tools, there are still many people who are still using DOS systems, not just this industry, most of which are due to the slow cost and technology upgrade!

After launching a new computer assembly language, Starry Sky Group gradually upgraded to launch related embedded operating systems and some basic software, and specially formed relevant technicians to form a software technology department to promote this language!

...

Starry Sky Group's current industry is still very uneven, and the overall industry is still a bit dangerous. Compared with the game industry that can make tens of millions of profits per day, Starry Sky Group is in a bad situation in software. So far, it is still investing, and the converted income is minimal. Currently, most of the profits in the software industry are advertising expenses.

For example, the ranking of some software in the software store in the Starry Sky Os mobile system, the special emoticon packages for Weibo users, and the cost of Big V certification!

Yang Yi fully understands this situation. Some industries cannot provide profits and are only used to maintain and cultivate user loyalty.

For example, video websites and music websites, but the storage costs are huge, and there are copyright costs. Although the profits of Starry Sky Group are not expensive, it is necessary to carefully calculate the investment in these gold-swalking beasts...

At present, Yang Yi is considering whether to enter the search engine market. Currently, the search engine rankings on the market are Google, Baidu, Yahoo, and Sogou. Although they are all in the fourth generation of technologies, due to algorithms, technology and investment, search engines are currently dominated by Google. Their owns account for 70% of the current market share, and the rest belong to other companies.

The core of search engine technology is to automatically download various web page content on the network with the help of a web spider program, and index and sort it. When users enter keywords to search, search engines search for results from the index of their own server.

So no search engine can really search the entire network. They are actually just searching for content that their own network spiders "crawled" and naturally have a certain lag and incompleteness. Therefore, the larger the company's search engine, the more useful it is, because their index database is more comprehensive.

Therefore, as a global search engine giant, Google also has the largest number of servers in the world, and the number should have exceeded one million, and has indexed more than 10 billion web pages around the world. Of course, these numbers are kept confidential, unless Google is responsible for technology senior management to know the exact numbers.

Most of Google's million servers are cheap (personal computer)-level servers assembled by themselves using accessories. They do not use server-specific motherboards and hard disks with more stable performance and higher price, but use a large number of personal computer accessories. Therefore, they are jokingly called the world's largest consumer of computers and a major private electricity user.

Of course, the stability of ordinary personal computer accessories is naturally not as effective as more expensive server accessories. Therefore, Google uses a large number of backup images, and the system will automatically assign tasks according to the load conditions of each server to ensure that the load of each available server is within the safe range, and promptly eliminate the impact of crash-related errors.

Google designed its own dedicated architecture on the three platforms of the Linux architecture gFsmapReduceBigTable, and cleverly organized these cheap assembled servers through algorithms and dedicated systems. These cheap servers form one of the most powerful supercomputer clusters on the planet at present.

The C programming tool developed by le is used for parallel operations of large-scale data sets. It will arrange multiple computers to calculate a task at the same time. Once one computer has a result, other computers will stop the task and enter the next task. Because multiple computers are used to perform one work at the same time, the occasional downtime errors in individual computers will not affect the execution of the overall task.

As for BigTable, this is a system used to process large amounts of data, suitable for processing semi-structured data.

However, although Google's server cluster is powerful, it has not signed up for the global top 500 supercomputers ranking, which is not surprising, because most of the supercomputers compare with single servers.

On this list, there are currently more than 20 groups of the top 500 supercomputers in the world for gaming services, and among them, there are more than 10 groups of Penguin Games, each with an expensive server weighing dozens of tons and selling at a price of up to one million yuan.

With the advancement of technology, servers are also being updated. For example, the former champion, "Earth Simulator" is a vector supercomputer jointly developed by many scientific research institutions in island countries.

The "Earth Simulator" is developed by setting up a "virtual Earth" in the computer to predict and analyze the large-scale calculations such as atmospheric circulation prediction, greenhouse prediction, crust changes, earthquake occurrence, etc. Its prototype is NEC's vector supercomputer "SX-5".

The "Earth Simulator" is composed of 640 "computing nodes" used for calculation processing and 65 network devices used to connect computing nodes. Each computing node is equipped with 8 NEC-produced processors with a maximum of 8GFLOPS (1 billion floating-point operations in seconds) and 16GB of shared memory. The computing nodes and network devices are connected by networks with a communication speed of 12.3GB seconds. The total length of the cables used is 2,800 kilometers. The entire set of equipment occupies a total space of 3,200 square meters.

The development of the "Earth Simulator" began in 1999, with a total development cost of 40 billion yen, equivalent to 1.8 billion yen.

However, Google's super server cluster cost is definitely higher than that of this server in Japan, and it is far more than that. Of course, the computing power is a hundred times higher. This is also one of the reasons why Google exclusively tyrants in the search engine market!

Search engines can definitely make a top-ranked company in the world, but the investment cost is also extremely expensive. Moreover, the investment continues and increases every year. Although computer technology is improving, the new data is also huge every year. With the increase of netizens, the investment is getting bigger and bigger!

But the electricity used for maintenance is a large part of the cost!

Currently, Starry Sky Group uses a lot of servers, whether it is a supercomputer used to make online game servers or a server cluster for various software downloads. In addition, Starry Sky Weibo's growing data storage needs!

This actually brings an opportunity to do search engine technology. Starry Sky Weibo originally has vertical search engines embedded, as well as games and forums. With a slight expansion in this aspect, a new product can be integrated!

Of course, this product must be another gold-swallowing beast, so Yang Yi has to consider it carefully!

This requires careful consideration. Yang Yi wants to launch not just this one. There is also a WeChat software that is being tested and is looking for a suitable opportunity to launch. In terms of hardware, Yang Yi also wants to launch a Star OS-based mobile phone before the launch of iPhone 4, but there are still many problems that have not been solved at present.

For example, the baseband issue, Yang Yi does not want to launch a 3G product. According to the current progress of global communication service providers, the 4G node has arrived. Some cities around the world are already under experimentation, and the progress is so fast. Of course, Yang Yi also participated. In the name of Starry Sky Fourth (Communication Technology) Laboratory, he published and applied for some professional papers and related patents in 4G, solving the final difficulties.

However, for some reasons, Starry Sky Group has not yet solved the problem of baseband chips, because this technology is too low-end and there is no suitable solution. The relevant authorization is still under negotiation.

Another reason is the talent problem. At present, there is a lack of a leader who can take the helm. A professional talent who can integrate supplier technology and his own technology!

Without Venus exploration, Yang Yi didn't know when Apple will release new products. She didn't want to wait for Apple's products to come out before revealing them. The public relations department authorized to start some hype. In fact, the appearance and circuit of the machine were set up in all aspects, a 4.3-inch screen, a 200w pixel front camera, a gyroscope, and a rear camera with 8 million pixels, with specially developed camera algorithms!

Camera lenses were also specially developed and commissioned to OEM manufacturers to produce them. A large number of manufacturers in China are making photosensitive components and lenses for mobile phone cameras, of course these are the lowest-end ones.

This is also because in recent years, due to the explosion of the mobile phone industry, almost no matter whether it is good or bad, there is a camera, but some are good or some are bad!

If you match a good phone, you naturally need to choose a good lens, but no manufacturer has paid attention to this at present!

Starry Sky Group currently has a team of about 100 people working specifically on this area, which makes Yang Yi attaches great importance to it.

In Yang Yi's determination to completely suppress the iPhone 4, this new product is absolutely the "Master King". Of course, the price is definitely not cheap, because the release price of iPhone 4 has not been determined yet, so the price has not been finalized!

...

The planning of all industries is closely related to Yang Yi's plan. The source of world promotion has been opened. Yang Yi is not sure what might happen after this "Pandora's Box" is opened, but just through some current information, you know that the world is changing too fast and is not in her control at all!

Spider-Man, warriors, mages, etc., all appear one by one. This is still something that can be searched on the Internet at present. In those underdeveloped areas, it is not certain that there is any situation!

Yang Yi had to arm herself urgently as soon as possible and strengthen herself. At present, her martial arts progress is very slow, and she can only use technological means to improve her safety as much as possible. After all, although she opened the source of this world, the result is not something she can control.

She didn't want this world to become a devastated world, not to mention that this world has a vast universe. At present, I don't know if there are any alien races in this universe!
