Rewrite the Technological Landscape

The history of GIT is also quite fantastic. At first, the Linux community refused to use the paid version control system, and dismissed the mainstream free version control system at that time. Until 2002, Linux was managed by the community through diff. The source code is sent to the father of Linux, Linus of Open Source Linux, and he then merges the code.

Obviously, this was a very inefficient approach, and then Linus had no choice but to go to BitMover. BitMover didn't know why, but gave Linus its paid version control system for free.

That was the way it was, but in 2005, the two sides fell out because people in the Linux community were cracking BitKeeper.

Ordinarily, the Linux community was at fault for this matter, and Linus should have apologized. As a result, Linus not only did not apologize, but also built a GIT of his own. Outsiders don't know what details are in it.

And about how long it took Linus to develop GIT, some people say ten days, some say two weeks, but logically speaking, Linus can really develop GIT in such a short period of time. He developed it a long time ago, and it should have been a period of time It was developed in such a short period of time after precipitation, and some even say that Linus deliberately fell out with BitMover.

The story behind this incident should be quite exciting, but it's a pity that the person involved is unlikely to tell the truth to the world.

But no matter what kind of story is behind it, the excellence of GIT has been recognized by the entire industry.

"Do you know the version control system?" Meng Qian asked, and about two-thirds of the people present raised their hands.

"Then let me give you an example. Today I asked Manager Ruan from the Operations Department to write a plan. After he wrote it, he felt that it was not good, so he revised it and saved it as a new plan. Afterwards, he got stuck. He wrote three more planning papers, and saved them all as files, so he now has five planning papers.

At this time, when he showed me five planning documents, no matter which version I finalized, he could take out that version instead of changing it back on the basis of the fifth version. This is version control. system.

The difference between a distributed version control system and a traditional version control system is that the version control systems on the market now store data on the server, and everyone who wants to extract data must go through the server.

But I want to do a distributed version control system, the data can be saved on the local computer. "

The rest began to stir, and the employees who knew the version control system couldn't help whispering, because Meng Qian's idea could obviously solve the very real problem of the version control system.

After that, Meng Qian focused on talking about several innovations of GIT, especially in content storage, and brought over several major advantages of GIT from later generations.

This is also Meng Qian's habit of leading the team to develop. Let everyone know what kind of thing we are going to make, let everyone have expectations for this thing, feel that there will be a sense of accomplishment after making it, and everyone will be more motivated.

After that is the explanation of the design, and the work arrangement of the industrial software development department is completed.

As for whether they will go out and say that they are the founders of the Open Source Alliance, they definitely will, but now Meng Qian no longer needs to hide this identity. Down to do something, the system.

A popular saying in later generations is that it is easy to build a system, but the difficulty is ecology.

For this sentence, Meng Qian has always been a little incomprehensible.

A win7 tens of millions of lines of code, a development team of thousands of people, billions of development investment, an Android, hundreds of millions of lines of code, 6 years of development time, an Apple system, has experienced four revolutions, and has invested more than a hundred 100 million, the Hongmeng system started to be developed in 2012, but was forced to turn the spare tire into a full-time job in 2019, but it was delayed again and again.

Do system. Very simple?

It is true that building a system, if there is no ecology, it is useless, ecology is the most difficult thing in the face of system competition, but making the system itself is very simple?

Originally, Meng Qian thought that everyone was comparing the development of the system with the development of the ecology, so he said this, but in later generations he saw on the Internet that many people said that dozens of people can make Android and Windows can be made. If so, the key point is at least judging from the reactions on the Internet, many people agree that the difficulty is the ecology, and the system is very simple.

To be honest, Meng Qian really doesn't know if more people really think that making a system is very simple, so simple that dozens of people, or even a few people can create a Windows

Maybe Meng Qian misunderstood this sentence. Anyway, in Meng Qian’s view, if the system mentioned here is to benchmark against Windows and Apple, it can only be said that companies like BAT and Huawei are fully capable of making A system of similar volumes.

After all, the design direction of the system is very clear. As long as the money and people are in place, big companies like them can definitely do what they want to do. It is even normal to do better than Windows and Apple in some aspects. .

Under this premise, what is difficult is ecology.

But if you don't have enough corporate strength, you won't even be able to make it through the system.

As for why it is difficult to build an ecology, the first is because of user habits. I have been used to using Windows for more than ten years, and suddenly I am asked to switch to another system. , or the system is particularly attractive, if the hardware is not changed, let me change to a new system with no difference on my old computer, few people have the mood to change.

The second is because of the profit-seeking nature of application developers. For them, I need to invest manpower and material resources to launch my product on a brand new system. I am willing to develop this new system only if it makes me think it is worthwhile. But the question is, how to make them feel worth it?

That is, you have a good competitiveness, that is, you have a good ecology, so how can you have a good ecology? That is, these developers enter the market first.

Therefore, a contradiction like the boss asking graduates to have work experience arises.

The third point is market inspection. For a project as large as the system, there will definitely be various problems. No matter how powerful the team is, it is impossible for tens of millions or even hundreds of millions of lines of code to be perfect.

Just think about what Android and Apple were sprayed with when they first came out, so the establishment of an ecology is not just about stuffing things into it. When the ecology gets bigger and bigger, there will be more and more problems, optimization and repair , A lot of problems will be in front of you, if one is not done well, people will abandon your system.

The fourth is a more realistic reason. It is impossible for a monopolized system to watch you develop. Microsoft knows that you want to challenge him, but can he just stand there and watch you develop? For him, it is much easier for him to use his monopoly to suppress a new system than for a new system to challenge him.

So for Meng Qian, when the Chinese version of XP will be released in a few months, the only thing he can gamble on is the mobile phone ecology, which has yet to achieve a real ecology.

But just a time advantage, is it enough to seize the mobile phone ecology? Meng Qian has always been as rigorous as possible in his work. Obviously, this advantage alone is not safe for Meng Qian. He still has the same view, that is, Google made Android, not Android made Google.

At that time, Google had the appeal to gather operators, hardware vendors and developers, and Apple had accumulated a user base of more than ten years. What did it have?

According to my plan, I will start to enter the computer industry in the next year or two. It will take a few years to compete, and then my mobile phone system should be released. Is it enough to accumulate users?

The shape of the mobile phone and the touch screen may be a competitive advantage, but they are still things that are easy to imitate.

So, what else can I do in the field of mobile phone ecology?

Reminiscent of his layout for the next few years, Meng Qian thought of something, self-developed application.

Many people may not know that there is a domestic operating system that ranks among the top ten in the global system rankings in later generations. This system is deepin, deepin operating system.

The success of this operating system is due to the interface and accumulation over the past ten years. Another very important reason is that he has developed more than 30 basic applications to ensure the daily needs of users. Then on this basis, purchase crossover transplanted Windows applications.

Meng Qian's rebirth and his own ability give him an advantage that he knows which software and which applications are the most commonly used, the most daily, and the most popular in the future. People who are not reborn do not know these things.

And not only does he know, he has the ability to develop.

So in the next few years, Meng Qian plans to build an app empire, because apps can bring one thing, users.

Although apps can be copied, users are not easily robbed. For a simple example, no matter whether it is QQ in the previous life or Fengxin in this life, even if someone else makes an identical one, they will not be able to rob users.

At that time, he will control the daily popular applications in his own ecology. It can be said that what Meng Qian can do is not only to meet the daily needs of users, but also to know that there are so few mobile applications now, and there were no applications when smartphones first started. How many.

Meng Qian can not only guarantee the daily life, but also guide the application development of smartphones.

Anyway, Meng Qian was planning to deploy application globalization from now on, and he was also planning to ignore the United States and grab the market outside the United States. In this case, the application may become a weapon of Meng Qian.

In the past, Google restricted Huawei because overseas users could no longer use applications such as Google Maps. Perhaps in the near future, this situation will be reversed.

Apple and Google provide everyone with a platform to build an ecology. They follow the shopping mall model. They make the shopping mall luxurious, reasonable and attractive, and wait for merchants to come in and open stores to operate the shopping mall.

But Meng Qian is following the business circle model. He is responsible for gathering users. Others see the traffic and want to open a store next to Meng Qian to make money, and these stores around Meng Qian are all his.

Meng Qian's strategy, he named it: application barriers!
