to farm together

I don’t know if everyone who engages in program development is a technical geek like Xuan Yi’an. Since he finished his work last week and the network was fixed, he has been staying at home every day.

Every morning, Xue Chengqi and Xue Chengqi went to the field to help water, and then they didn't go out when they got home, or more precisely, they nestled in the room.

Xue Chengqi was particularly curious about whether Xuan Yi'an would be bored staying in the room, what to do when she was bored, and whether she would get sick from being bored in the room all day long?

He also went to ask grandma specifically, but grandma said that it would be fine if he got used to it, and he would be seriously ill if he went to the village center to chat someday.He even complained that he didn't talk to her, and praised Xue Chengqi by the way.

But grandma also told Xue Chengqi very proudly that Xuan Yi'an was a very diligent and hardworking child since he was a child.Every day after work, I go back to my room to study, and I don't go out to play with the children.

But also because of this, he has never had many friends, and the only friend grandma has seen for so many years is Xue Chengqi.What grandma was most worried about was that he would not be able to marry a wife like this, so she also asked Xue Chengqi to introduce more girls who knew her to An An.

Then Xue Chengqi patted his chest, and confidently assured his grandma that he would find her a sensible, filial, beautiful and capable grandson-in-law!

Xuan Yian didn't know about this, he was immersed in his own programming world.Speaking of which, many of Xuan Yi'an's college classmates are already married, and those who are not married basically have girlfriends.In the classmate group last year, there was a classmate teasing whether Xuan Yi'an would eventually marry Program as his wife...

The things in the field are almost too busy, all he can do is help watering or something, and Xue Chengqi is mainly responsible for solving any remaining problems, after all, he has a specialization in surgery.

Then Xuan Yi'an should return to his professional field.Although they haven't seen even a root vegetable in their fields, they are also starting to prepare for the Internet service they will provide in the future.

In Internet applications, whether it is an APP on a mobile phone or other terminals, or a website page, or an official account or a small program in WeChat, in the final analysis, it is actually the front end.Simply put, it is the interface that users can directly see and use in actual operation.

The front-end depends on the background, which is the support of the entire service system.No matter how fancy and cool the front-end is, if there is no strong back-end support, the front-end experience will fail, and the entire product will also fail.

Of course, the front end is also important, otherwise, whoever wants to use an interface that is so ugly that whoever uses it will complain about it. No matter how powerful the background is, it will be useless if no one uses it.

How to put it, the background is the foundation of the service, and the good-looking front end is the value-added item of the service.Only with background support can various pages be made on this basis.As long as the foundation is solid, you can toss about the above, you can change any page you want, and you can make any effect you want.

So what Xuan Yi'an has been thinking these days is how to build this backend, how to integrate this basic framework, and write a software development plan while thinking.This time, the proposal book really follows the software development process.

The first is demand analysis, which is considered from the perspective of different terminals. The background needs to provide services for mobile phones, PCs (which can be understood as browsers on computers), and WeChat.

From the perspective of product positioning, their products are mainly agricultural products, or other related services extended from agricultural products. To put it bluntly, they are mall-like services.

So to sum up the needs, it is to build a mall-like background that can provide agricultural product promotion and trading services for mobile phone, PC and WeChat users at the same time.

After the requirements are clarified, the next step is to implement the plan.For different user terminals, it is necessary to consider the characteristics of different terminals and perform compatible or customized processing.

Then what functional modules are specifically included in the mall service, such as product listing, release, review, recording, product display, search, purchase, etc., as well as order management, user management, payment function, customer service center, etc.

In addition, what are the characteristics of mall services and what measures need to be prepared to deal with them.For example, many shopping malls have some spike activities. At this time, the server is required to support high concurrency and high availability.And for a good user experience, stability is a must.Finally, commodity trading involves money transactions, so the security requirements are also very high.

Xuan Yian recorded these functional modules, features, and various possible problems one by one, and supplemented them while thinking.

Then how to implement these functions; what kind of technology to use for different features; what solutions are there for possible problems.

In general, it is actually a matter of technology selection.This has to be done according to one's own technical system and combined with the experience of the predecessors, so I won't go into details.

In short, for several days in a row, Xuan Yi'an was thinking about these issues, and then sorted out a detailed implementation plan.Including what technology to use, the detailed flowchart and sequence diagram of the whole project, and related database design.

After completing the proposal, the next step is the real technical realization, that is, you can start typing codes.But before starting to code, Xuan Yian decided to buy a desktop computer with better configuration.

Xuan Yian used to use a laptop all the time.As for laptop development, except for the convenience of portability, it is no match for desktop computers, and desktop computers are also used for development in companies.

I usually study by myself, write a small demo or something, and there is no problem with a laptop.But to really develop and do projects, it is more difficult to use a laptop. If you open a virtual machine or something, you will get stuck, and if you open a few more services to run tests or something, you will probably get stuck.

When he was in W City before, he didn't buy it because he hadn't received an order and the house hadn't been settled yet.Now that it is clear that development should be done at home, the desktop computer is naturally indispensable.

In addition, grandma should go to the hospital for a re-examination.So during dinner, Xuan Yi'an told Xue Chengqi and grandma to go to the city.

Grandma didn't really want to go. She said that she ate and slept well every day, and went out to exercise every day. She was in good health.But with Xue Chengqi present, he naturally happily agreed in the end.

After dinner, Xuan Yi'an was finally not in a hurry to go back to the room, because his plan had already been written, so he chatted with grandma in the living room for a while.

When grandma went back to her room to sleep, Xue Chengqi finally couldn't help asking his questions these days: "Yi'an, will you be bored in the room every day?"

"I'm working at home, how can I be bored?" Xuan Yi'an was quite surprised when she heard that, just like she used to go to work, she worked in front of the computer every day. Isn't this normal? What's so boring?

"Uh, you used to work in the same room all day long?"

"Otherwise, the office is bigger than the room, and there are more people."

"Okay, but home is not an office, you won't feel bored in it alone?"

"No, it's easier to be alone in a familiar environment. I feel better than the office."

"Well, what I want to say is that you can come out and relax more, it's not good to be bored in the room by yourself."

"Oh, well, I don't feel bored."

"...Are all of you programmers technical nerds?"

Xuan Yi'an was taken aback for a moment, and after seriously thinking about her former classmates and colleagues, she replied, "It seems that most of them are."

"Then none of them have girlfriends?"

"Uh, it seems to be all there."

"Then they definitely don't have your house!"

"?"

"Otherwise why don't you have a girlfriend?"

"That's what you said, didn't you?"

"Tch, the girls chasing me have to go to the village brigade, but I don't want to look for them. If I want to look for them, I have to find someone from the village to farm with me."

"It's easy to handle. Tell the second aunt tomorrow and make sure that all the girls in the village will come to your house."

"...Please forgive me. Feelings are all about fate, just like farming. One radish and one pit. If it's yours, it's yours. If it's not, you can't force it."

"Well, that makes sense."

"But fate doesn't come out of the house. If you don't go out, where can fate find you?"

"Then who knows, the Internet is so developed, there will always be a radish and a pit, right?"

"..."

The two chatted for a few more words, and then went back to their rooms to sleep.

The next morning, when Xue Chengqi and Xuan Yi'an came back after watering the fields, the three of them set off.

First, I went to the hospital and asked a doctor to check my grandma's legs. The doctor said that the recovery was very good, better than expected. It seems that I really exercised well, and there is no need for re-examination if there is no problem later.

After coming out of the hospital, it was time for lunch at noon.Xue Chengqi invited grandma and Xuan Yi'an to his house for lunch, but grandma felt that it would be bad for her to go to someone else's house as a bad old woman, and Xuan Yi'an didn't want to go, so she declined.

But who was Xue Chengqi? He immediately told his grandma that he hadn't been home for more than ten days. His mother thought he couldn't do it. She also said that she wanted to get to know grandma, so lunch was prepared for the three of them.

Then if he went home alone, no one would escort them, Xue Chengqi expressed his concern.And he still wants to take his grandma to play. If we separate, it will take a lot of time to pick up people this time.

In the end, he said that their food is very delicious, especially the small tomatoes at home. It is said that there are still many growing in the vegetable garden, just waiting for him to go back and pick them.

Seeing that grandma started to hesitate, Xue Chengqi made persistent efforts, and leaned into grandma's ear and said, "Grandma went to my house and asked my mother to find a girlfriend for An An."

Then, grandma happily agreed to go to Xue Chengqi's house for dinner.Xuan Yi'an had no choice but to look at him contemptuously, why is such a big man acting like a baby?Whisper?I used to think this guy was nice, when did he change? !

After eating a sumptuous lunch at Xue Chengqi's house, the two of them went to his vegetable garden to pick a bunch of fresh vegetables, especially small tomatoes, and left Xue Chengqi's house with a big bag full.

First send Xuan Yi'an to the computer city, and then grandma happily left with Xue Chengqi, saying that she wanted to follow Xiao Xue to a fun and beautiful place.

Xuan Yi'an walked around the computer city alone, and then selected a store, asked the boss to take out the accessories according to the configuration he chose, and then assembled the accessories.

He took the packaged computer to the entrance of the computer city on the first floor, and after waiting for a long time, Xue Chengqi brought his grandma over.Putting the computer in the trunk, Xuan Yi'an also got into the car and sat in the back with grandma.

Then on the way back, I listened to my grandma happily sharing what she had just seen and heard.
