"Wang Jian: Online" reading notes

Confusion about the Internet and data:

The people who are best at using data are often not the ones who create it. Just having data is not necessarily valuable. (In its early days, Google’s data was far inferior to that of Microsoft and Yahoo, but Microsoft and Yahoo chose to outsource search to Google. Alibaba’s current understanding of data will not exceed Suning’s understanding of e-commerce.)

The most valuable data is often the data that is incidental to the original business and has been accumulated without purpose. (Don’t think about using data to improve existing business. You should use big data to do things that you couldn’t do before)

The name of “big data” is wrong. It should be called “online data”. "Online" is far more revealing than "big". If the data is not online, no matter how large it is, its value will be limited. The data is online, that is, the data is updated in real time, the data is fully shared, and it is extremely easy to obtain. (People's understanding of "cloud computing" is still relatively superficial, and it is not related to big data. Cloud computing is the basis of big data. Without the cloud, we can only do small workshops and cannot do big data. Data sharing seems to have encountered a problem Problem, now everyone has data firmly in their hands. How can data be standardized like steel so that it can be continuously circulated? )

Misalignment of cloud and computing:

Private Cloud and hybrid cloud are not clouds at all, they are just upgraded IT solutions without changing the medicine. Only the public cloud is the real cloud, which can be shared on a large scale and truly provide services instead of selling equipment.

Many people still only regard the Internet as a channel, rather than a change in ideas and business models.

The dilemma between offline and online

Examples of Skype and Tencent QQ: There is the concept of "offline". Even when the other party is offline, messages and files cannot be sent. WeChat assumes that users are online all day long and there is no concept of offline.

Online is common sense in the new era and represents the future.

Online is the instinct of the Internet, and the cost of obtaining data from the Internet is almost zero. In the future, whether you are awake or asleep, you will be online every minute.

The essence of big data is online, and it is two-way online. The accumulation of data must be online, and the output process must also be online.

Paying attention to user experience is correct nonsense. Traditional industries are no worse than the Internet. When the Internet first appeared, the experience could be as bad as it was. The key was to solve problems and create value.

Wearable devices are revolutionary. Not only do sensors collect data, but more importantly, they connect the data to the Internet, making it online.

Digitalization is the basis for online data, but digitalization and online are two completely different realms, which is the difference between Founder and Google.

Data is more valuable than information

Cloud computing is equivalent to the power generation industry back then, cloud storage is the steel industry, and big data is the Ford production line. (My understanding: Data is the steel industry, and algorithms are the Ford production line)

Data must flow to be valuable.

Data is a strategic resource

The power of big data is that it turns sand into silicon. People who brag about having rare data every day will find it difficult to develop their own core competencies.

Data is the core competitiveness, one is the data itself, and the other is the data processing capability.

Nowadays, the competitiveness of a country is measured by how much electricity it uses. In the future, it should be measured by how much computing power it consumes.

The Internet still has at least another thirty to fifty years until we make our brains part of the Internet.

Telescopes, Microscopes and Radar

People did not invent the telescope after knowing the solar system in advance. Instead, he invented the telescope and looked east and west to discover the solar system.

Using data to solve a known problem will not be the greatest value of the data, at most it will be part of the many values. Data can allow you to see problems you don’t know about yet and help you solve them at the same time.

Everyone is on the Internet, and no matter what they do, they will definitely leave clues in some corner of the Internet.

The Alibaba Cloud platform is like a bank. In the future, people will store data in Alibaba Cloud just like depositing money in a bank.

In the early days of the Internet, people were worried about viruses and attacks; today, people are worried that the precipitation of data will cause unpredictable damage to themselves. As society moves forward, we will definitely lose a lot of things, but we still have to believe in and embrace the future.

Computing is a new public service, just like electricity

When people start a business in the future, they will not need to buy their own servers; just like when people open a processing factory, they will no longer It’s like building your own power station.

Cloud computing should be universal. Now many companies are doing vertical clouds such as education cloud, health cloud, e-commerce cloud, game cloud, etc. In fact, they are just making customized generators instead of building power plants. . It is better to call it cloud education or cloud health. Use the cloud to solve vertical problems instead of creating a vertical cloud.

There are no public clouds and private clouds, only public clouds

Those who advocate private clouds take advantage of people's fear of new things and talk about cloud computing, but in fact to sell software and hardware to you.

The security issues of public cloud will be solved sooner or later, and its cost advantage will completely beat that of private cloud.

A power company should never think about making refrigerators, and a cloud computing company should never think about making applications. ?

Vibrant mobile, quietly online

The mobile Internet is an Internet that is more online than the traditional Internet. The iPhone is more popular than the iPod touch. It is 3G/4G rather than wifi that promotes the popularity of mobile Internet.

The iPhone is not the first smartphone, but it is the first mobile phone to provide an online experience. (In 1996, Finland's Nokia released the Nokia 9000 Communicator, which could access the Internet; in 2001, Japan's NTT DoCoMo provided 3G mobile phone services for the first time.) (ps. The truly successful product is often not the first, but the one that moves towards Enough efforts are made in the right direction, and quantitative changes lead to qualitative changes)

Apps are good, but the Web is better

Making apps is like making potted plants in other people's gardens. Really viable things must grow in the forest. Mobile Internet is just a small wave in the Internet trend.

An operating system born for online use: YunOS

In China, there are many companies that want to develop mobile operating systems, and many of them are better equipped than us. (The person who got things done may not be the most qualified person at first, but he should be one of the more qualified people)

An independent account is the most basic condition for online experience.

Many people say that operating an operating system is difficult, but if you don’t do it because it is difficult, it means that the matter itself is not important enough. (If we need to use words such as "effort", "perseverance" and "perseverance" to motivate ourselves, it also means that this matter is not important enough.)

Xiaomi and YunOS have different value orientations, and they have ignored things similar to Huaqiangbei small and medium-sized enterprises believe that these small enterprises will only copycat. We believe they are a transformative force in the industry.

It’s not the Internet of Things, it’s the Internet of Everything

(I feel more and more that artificial intelligence and blockchain may be the two cores of the Internet of Things. Artificial intelligence solves automatic and intelligent problems, distinguishes Blockchain solves the communication security problem between devices)

Future scenario: Once there is pressure on the power supply in a certain area, there is no need to turn off the power and reduce the power. All air conditioners will automatically turn down one degree, and people will hardly feel it. time to solve the problem. The milk carton is equipped with an RFID chip, which can not only trace the source, but also the smart refrigerator can know the speed at which you consume milk and remind you to purchase it regularly. RFID can also be sensed when you throw a milk carton into the trash.

Don’t underestimate the hardware. You can handle the horizontal ones, but you may not be able to handle the vertical ones.

It’s not that we don’t want to be Apple, it’s that we don’t have the ability. Not everything that makes sense can be done.

Finding one's own positioning is the company's core competitiveness. (It is also everyone’s core competitiveness)

Computing becomes part of human capabilities

Cloud computing can liberate the productivity of creators.

Data is the new wealth of the world

Offline data is easy to falsify. Once online, a bunch of data will be generated that you don’t know whether it is useful or not, and it will be extremely difficult to fake it.

Going from purposeful to purposeless is also a big change. Data collected deliberately must have limitations. Data is not collected, but precipitated. What is collected is information, and what is precipitated is data.

The prospect of artificial intelligence in the transportation field: cameras collect various data in real time, the system automatically schedules in the background, and traffic restrictions will become a thing of the past.

We are optimistic about the future of Hangzhou. It will be a city that brings China to the cloud. It will also become a city that uses computing to change the world.

The Internet has become an infrastructure and an innovation platform

The Internet has the following three characteristics to become an infrastructure: scale, cost, and convenience.

Data has become a means of production and a natural resource

As a means of production, data needs legislative protection. The question "whose data belongs to" is very important. Failure to understand data ownership will affect the long-term development of the information economy. Like the determination of land ownership and use rights. (Data must have clear ownership and be as mobile as possible. This seems to be a contradiction. Once the data flows, others may back it up. How to solve it? )

The data itself has no value, and it must be passed through Calculation and exchange produce value. Here, what is exchanged is the value of the data, not the ownership of the data.

On April 14, 2016, the European Parliament passed the General Data Protection Regulation: Definition of Jurisdiction and the Right to be Forgotten.

Computing has become a public service and an energy power

The computing economy generated by fusion

Data is like oil. Crude oil is valuable, but it is not the most valuable place. It is more valuable when refined, so the United States is more powerful than Saudi Arabia. Processing data is like refining crude oil. Algorithms are the method of refining crude oil and are the soul of the computational economy. (But it’s very strange: now many experts are saying that everyone’s algorithms are similar, and the key depends on who has more data? Is it because the progress in algorithms is too small now, and we can only win by relying on large amounts of data?)

The Pagerank webpage ranking algorithm affects the past of the Internet, and the blockchain algorithm may affect our future.

Law 1: Every bit is on the Internet (IPV6 can assign an IP address to every grain of sand, as if it was specially designed for online)

Law 2: Every One bit can flow on the Internet (it is not called online when it is connected to the Internet, only when data flows is it an online system. This is why I am opposed to private clouds.)

Law 3: Bits are everywhere Every object represented is computable on the Internet.

In the new era, don’t doubt whether a person will have a chance to start a business.

Privacy is not a problem. The entire evolutionary process of human history is a process of gradually sacrificing privacy. We live in one room at home, but we live with several classmates when we go to college. This sacrifice of privacy is huge, but we choose to accept it in order to study.

For at least 50 years, we will still do things around the Internet.

Using Wi-Fi is an excuse in the Internet era.

Drones are an example of big data applications.
