Rebirth 2010: I taught Mr. Lei how to make a mobile phone

Chapter 470: The Other Shore System, the Gods Fear It!
The rush to buy tickets for National Day has arrived as expected.

Countless passengers who wanted to travel during the National Day Golden Week found gratifying changes when using the new version of the 12306 system.

It's really because everyone's memory of the bad ticket-purchasing experience in the past is too deep, so after using this new ticket-purchasing website, this Dove-like silky experience makes them feel unreal, as if they were reading a novel.

This allowed the passengers who had finally seen the light at the end of the tunnel to praise their tickets online.

"Before, lags, crashes, and no response were commonplace. Now, it's smooth and seamless, with a great experience. I can buy several tickets at once without any pauses. I give a thumbs up to 12306!"

"The old verification code that used to compete with us and test our eyesight is finally out of service. Look at how simple the live verification of sliding puzzles is now. I know that I can give feedback to the other side. They can listen to the voice of the masses and actually do it."

“Although all the ticket-swiping software has been banned, the official website has its own automatic query function, which saves me from clicking it again and again. It’s a pity that it would be better if it could support one-stop purchase with information set in advance.”

"Now when the ticket sales time comes, the button changes color immediately, and there is no lag. If you are late, you will be notified of the queue. It is also considerate to tell you how many people are currently in line. The information is clear at a glance. It is a product of the other shore. I am so impressed!"

"Although I still didn't get the ticket this time, I don't blame the system, I can only blame my own slow hands. Later, I used the standby function and was able to buy the ticket."

"Hey~~~ I said at the beginning that we should have asked Bi'an to do it a long time ago. They are a big company with experience. They have no problems in the national red envelope grabbing. They bought a few tickets with ease. They clicked and did it all. Look at the effect now."

"At least I have done something practical for the people. I am content and happy with it."

As netizens discussed it heatedly, 12306 received rave reviews, and central media began to report on it, followed by other media outlets.

"I give 12306 a thumbs up": "The above is what our reporter interviewed travelers at the railway station recently and asked them about their views on the new version of 12306. They all gave very high praise, which shows that this revision has indeed brought great convenience to people's daily travel."

"A good example of cooperation between government and the public, the ticket purchasing website has a new look": "Since the restructuring, the China Railway Corporation has broken the past routine, recruited talents in an unconventional way, and took the lead in cooperating with private enterprises to build a new era ticket purchasing platform. This also echoes the spirit put forward at the two sessions at the beginning of the year, and never forgets the original intention.

This also lays a solid foundation for subsequent development."

"This year's National Day travel has reached a new high, and the 12306 system has given the green light to passengers' travel and become a booster."
".The passengers who originally thought it was a flash in the pan are now completely relieved. The difficulty in buying tickets has finally become a thing of the past.

This cross-border cooperation is a successful exploration and implementation of Internet + by the relevant departments. The results are obvious to all, and it also sets an example for other departments.

Among them, Bi'an Cloud Computing has once again withstood the test, adding another highlight to its previously brilliant resume. Well done to them all."

After reading the report, the director finally felt proud and all the previous gloom was gone. He thought that the official media still had a decent level. It would have been better if it hadn't said the last sentence.

But everything depends on human effort. Now that the system is in place, we can wrap it up.

Two hours later, he personally went to the Institute of Technology to hold a meeting and gave the latest instructions on the subsequent development of the 12306 website.

".Comrades, we have achieved unprecedented brilliant results during the National Day ticket rush. We can see and hear the media reports and the people's voices.

The most important thing is that this matter has been recognized and verbally praised by the relevant leaders, which is inseparable from the unremitting efforts of everyone here.

Next, our key work will focus on the subsequent operation and maintenance of 12306, continuously improving our service quality, seeking innovation, change and development.
In the next step, we will continue to deepen reforms and strengthen system construction around the core idea of ​​Internet +.

I would like to briefly share the following points of view.”

When the leader said this, everyone present took out their notebooks and started taking notes.

An hour passed, and these people wrote down a few lines in their notebooks.
"1. 12306 is our own 12306. We will take back all system permissions from the other side and operate and maintain it independently;

2. The modifications left over from before will be iterated and improved in the second phase of the project that will be launched soon;

3. Negotiate with the other party and add additional terms to ask them to hand over all source code. If the cloud service is not easy to migrate, it can be left unchanged for the time being! "

". Let us continue to work hard and make further progress, so that the outside world can see our efforts and changes. We must adhere to the development path from nothing to something, and from something to excellence.
In this situation, I would like to end with a poem that just came to my mind, which is.
Thousands of ships pass by the sunken boat, and thousands of trees bloom in front of the dead tree! "

In the leader's rhythmic and passionate poetry recitation
The audience burst into warm applause
The meeting ended successfully and everyone was happy.

On the last day of September, the rush to buy return tickets came to an end.

Online, the 12306 ticket purchasing system once again stood the test.

Offline, a meeting with a strange atmosphere was taking place, and the two parties were the two behind-the-scenes heroes reported by the media.

After negotiations, the two parties finally confirmed and signed a supplementary agreement, which stipulated that the final payment of the project would be settled after Bi'an handed over the system source code.

That evening, the group from Bi'an returned to the headquarters.

In the construction of this system, Bi'an invested real money, including cloud computing servers, a research and development team of nearly 100 people, and various software and hardware construction. All these added together, the research and development costs were less than 100 million yuan.

Just like later, the same four kings, the same special effects team, the special effects of a movie with a 30 billion investment were not as good as a 3 million game. It can only be said that Party A is different from Party A.

However, the profit of this project by Bi'an nearly tripled, and the final payment was received, so it can be considered a successful conclusion.

Chen Mo was puzzled to see Wang Jian's expression of losing both his wife and his army.

"The source code has been given away, and the final payment of 2 million has also been received! So what does it mean that you have a drooping face like a defeated rooster?"

"Ah, it feels like I've raised a child myself, but now I'm giving him away just as he's grown up and has some potential. Well, selling him to the imperial family, I feel a little uncomfortable."

It is true that people who work in technology tend to get stuck in a rut, but there is no such thing as perfection in the world.
As a boss, you must not only share the same hatred for the enemy, but also the spiritual mentor Chen Mo is online.

"From another perspective, does the system we make bring convenience to people's travel?"

Wang Jian nodded.

“Has our system made society a little better? Has our system made money?”

Nodding repeatedly
"That's right. Isn't this the purpose of us getting this system in the first place? As long as the other party doesn't make any changes to this system, there will be no problems for at least the next five years."

"But when we went there this time, you could clearly feel that they were eager to try, just waiting for the source code to be delivered to them and start making changes."

"That's better." "Uh"

Wang Jian recalled that scene.
When the boss finished signing, he looked at the people on the opposite side, who were all very arrogant and confident of victory, as if saying, "Your wife is in my hands and I can do whatever I want to her."

Then he saw the boss looking around at the other group of people and casually asked three questions:

"Have you ever taken a train? Have you ever bought a ticket using 12306? Do you know how many steps there are in the 12306 ticket purchase process?"

In an instant he noticed that the smile on the other person's face froze, and the conversation fell silent. Such a simple question seemed to ring like a loud bell in the other person's ears.

After a while, someone jumped out and said something in a timid tone, "Ah, you guys made the system, of course you know that."

Then the boss took out a stack of materials as thick as a brick from his bag, gently placed them on the table, and pointed at the materials with his finger.
"These are the 38726 opinions, suggestions and feedbacks that we have collected from users in the past six months. We have sorted out 1273 requirements, and now the online system is running 273 of them. These are only part of the original feedback. Do you want to see them?"

For a long while, no one took any action.

"I originally thought that if you could answer the three questions in the three lists above, I would be fine to give them to you, but now it seems that there is no need."

Before leaving, the boss carefully put the things back into the bag, then looked at the other leader,

"Anyway, we have handed over the system of the Other Side. I won't stop you from changing it if you want. The disclaimer clause has been clearly stated in the agreement. If there is any problem, it has nothing to do with the Other Side.

Then be well and look forward to our next cooperation! "

"I hope they change it, otherwise how can we generate secondary income?"

Hearing his boss's words, Wang Jian seemed to remember something and said excitedly, "Well! I can guarantee that even if the elite technical teams of BAT were to modify this system, it would be a big problem, not to mention those half-baked technical experts who are just sitting there doing nothing."

"Hey, I hope they can listen to us and stop making trouble, otherwise we can only make money with tears."

Seeing his boss' compassionate look, Wang Jian lost all his negative emotions and just thought that his boss was a nice person.
In order to solve the problems encountered by the people, they are willing to do all the dirty and tiring work.

"This official cooperation case has really allowed Bi'an Cloud to show off its strength to the domestic and overseas markets. Next, we need to take advantage of this favorable situation and cooperate with Li Jianchao overseas to expand Bi'an Cloud Computing's influence in the international market and take our sales to a higher level!"

"Yes!"

Over the past year, under the leadership of Li Jianchao, in addition to the marketing and development of the group's products in the international market, the overseas market has also made many efforts to build the local market for the Bi'an Group and maintain good relations between the government and enterprises, and achieved good results.

As one of the major well-known products within the group, Bi'an Cloud has been highly recognized in the global market thanks to the past cases of China's 1.3 billion people grabbing red envelopes and Double Eleven and Double Twelve.

Currently, our business footprint has spread across Europe, America, the Middle East, Southeast Asia and other regions, serving more than 50 business customers.

Bi'an Cloud's international service network covers more than 12 countries around the world, with 38 availability zones, providing customers with stable and reliable products and technologies.

Whether in the bustling cities of Asia, the ancient streets of Europe, or the vast plains of America, Bi'an Cloud's services are like "ubiquitous" guardians, ensuring that customers' businesses can run smoothly and steadily, and currently still maintain a record of 0 failure rate.

Therefore, Bi'an Cloud has become one of the world's top four cloud service providers after Amazon AWS, Microsoft Azure, and Google Cloud.

The rest are IBM, Tencent Cloud, Baidu Cloud, and Alibaba Cloud.
When Bi'an Games fell into a slump and saw its revenue decline, Bi'an Cloud took over the banner and became a new profit growth point, contributing nearly half (nearly 200 billion) of the revenue.

Wang Jian left the headquarters and drove to his own territory in Wangjing. Thinking back to what he had just realized, he felt a little ashamed, and for a moment he was filled with endless emotion.

There is a saying circulating among the senior executives of the other side: “The boss is the boss”, and the value of this saying is still increasing.

When the 12306 system was being designed, the boss came, contrary to his usual practice, saying he was just there to listen, but ended up becoming a participant as he listened.

At the end of the meeting, I and my boss had a disagreement on the design concept, which was no less than a dispute over the route!

A system will adhere to the following principles from the beginning of its design: high cohesion and low coupling, Liskov substitution principle, interface isolation principle, dependency inversion principle, and Demeter principle.

It sounds complicated, but it’s actually not simple at all, so I won’t explain it.

In short, the purpose of these principles is to help the technical team design an excellent system that is robust, maintainable, and scalable.

To put it simply, it is a system that is simple, easy to modify, not prone to problems, and can cope with various new changes.

The boss is technically savvy, but that time he went against his norm and emphasized "high cohesion and high coupling", meaning that the functions within the modules or components are closely connected, but the connections between the modules or components are also close, to the point where one move affects the whole body.

Moreover, each module must be "extremely simply encapsulated". A function that can be implemented with a hundred lines of code will be compressed to 50 lines, 30 lines or even less.

The advantage of this is that it is difficult to modify. Even if you change a word, a certain function may not respond. If you are unlucky and change some code at the root, it is possible that the whole site will crash.
The boss clearly admitted that their design concept was correct, but I didn’t understand why they did it this way.

Not only myself, but all the technical staff present at the time did not understand. They knew that the boss was a technical person, and although his hands-on ability might not be better than theirs in the past two years, he definitely had vision.

But the more I thought about this, the angrier I got. I even slammed the table in front of my boss and deliberately said, "Boss, you don't understand technology!"

After saying this, he was shocked by the young boss's eyes which were vicissitudes of life and somewhat sad.

"Wrong, you don't understand the national conditions!"

As soon as the words came out, it was like thunder in the silence.

Some technical colleagues in the team who had worked with the official on projects only realized it at this time.

Looking back now, if I had really developed it according to my original model and handed over the source code, that system would have become a fish on the chopping board.

Thinking about the quick glimpse I had before, and the densely packed modification requirement documents, within half a year, the system will definitely be changed beyond recognition, and by then even the system developed by myself may not be recognizable.

Then the second and third phases will have endless descendants.
Just like repairing roads, who knows how much it will cost to transform the system?

Only at this moment did Wang Jian understand his boss's good intentions and foresight. It can be said that the design concept that his boss insisted on at the beginning directly cut off this possibility at the root.

According to what the boss said at the end, if you want to change it, you have to pay more!
Facing the setting sun, Wang Jian smiled.
The other shore system, the gods fear it!
