When the programmer opens the plug-in

Chapter 90 Ten Times Engineer
The teacher in the computer room heard what Cheng Wen said, and wanted him to try it.

But Yao Shao took the call, "Call the other party first to explain the situation, and see if they let us intervene."

After all, this is not their project. If they take over without asking for the consent of others, it will make others unhappy.

Although it is for the students' learning, but also care about the face of the peers!
If there is a problem with their project, others can help them solve the problem. If it is a teacher or a student at the school, it is okay.

But this is the people outside. Will they feel that they have lost face, and then use it as an excuse that they will not undertake the maintenance work in the future, because they let others touch their things.

"Okay, I'll call the other party and ask about the situation."

During the phone call, the teacher in the computer room asked Liang Zian from Shierfang Technology for advice. Liang Zian also said that if there is technology here, he can take a look. He is rushing here in a taxi.

Cheng Wen answered the phone and asked the other party a few questions, such as what is their technical architecture?
What is their server password?And what should it look like when running correctly?

The other party told Cheng Wen on the phone that they used a system deployed by docker and k8s, and also told Cheng Wen the password of the server, and that they should be able to access their website normally if it is running correctly, and there are videos and other things in it. Everything should work normally.

In the end, Cheng Wen also said on the phone that he can take a look, but he can't guarantee that it will be done, but he can guarantee that it will never make the situation more complicated.

Cheng Wen logged in to this server, and then looked at their services. It seemed that the services had been activated, and then looked at their historical commands.

I found several commands to start the service and re-executed them.

In fact, if their services are generally started, there is probably no problem if they are executed again. At most, an error will be reported during this execution, saying that the previous service is already running. Please do not run such errors repeatedly.

It is also because of this Cheng Wen that he dared to run the relevant commands again.

After running, Cheng Wen saw that there was one more service process, and probably judged that it should be because the server was shut down and restarted, and their service did not restart, but Cheng Wen tried their project and still could not access it.

"Mr. Zhang, can you ask them to see if there are any documents?"

Cheng Wen asked, half of his effort was on testing, and more than half of his effort on testing was on test cases. Now he doesn't know their functions, so Cheng Wen can't locate their problem in the first place. Where is it.

"Okay, let me ask." This time the teacher in the computer room did not call to ask the technician, but asked the teacher in their school.

Because in his opinion, if there is a document, it will be brought along with the project when it is delivered.

Sure enough, they finally found a document and sent it to Cheng Wen.

Cheng Wen read this function document and immediately wrote a simple test case.

But this time the time is tight, he didn't write all the test cases completely, he just wrote the functional modules.

See which one has red, and he will continue to write which function.

In this way, the specific problem was located very quickly.

Then he went to look at the source code. At this time, the technicians over there had already arrived at the school by taxi, but they had just entered the gate.

There is still some distance to get to their computer room.

Cheng Wen used these few minutes to prepare to change their code.

Just as the technician got out of the car and walked into the computer room, Cheng Wen also repaired part of their code.

When he saw Cheng Wen opened their code, he carefully looked at the code on Cheng Wen's computer and was very surprised.

Because Cheng Wen opened the most complicated part of their previous business, and there were often problems here when they were testing before, and the bugs in this part accounted for more than half of the total number of bugs.

So when he saw Cheng Wen open this piece of code, he felt that something went wrong again.

Just when he was about to speak and replace Cheng Wen, he saw Cheng Wen typing codes at an extremely fast speed.

Seeing this, he decided to wait a little longer and see how this master handles it first.

It wasn't that he was being lazy, but he was stunned by the speed of Cheng Wen's hands. Cheng Wen also brought his keyboard this time.

With such a fast hand speed, he felt that Cheng Wen's skills would not be any worse.

You must know that writing a program is a process of thinking, and hand speed has never been a bottleneck.

But if the brain speed is very fast, sometimes hand speed becomes a problem. Liang Zian has never seen such a person.

At least after working for so many years, Liang Zian of Twelve Square Technology has never seen a programmer whose hand speed is so fast, even chatting with people is not so fast, okay?
Liang Zian wanted to wait for Cheng Wen to fix the problem before he took over.

After 1 minute passed, Cheng Wen corrected the problem, and his subordinates stopped moving.

Liang Zian was dumbfounded, even if he was allowed to go, he couldn't guarantee that he would be faster than Cheng Wen.

However, Cheng Wen has the invincible prompt of the test case and the blessing of his keyboard, so it is much easier for him to find the problem, and the speed of fixing the problem is also much faster.

But all this is not the case in the eyes of the technician.

Amazing!
The ability to find bugs is so strong, he has done his best, and it has been less than half an hour since he answered the phone.

"Are you the technician who talked to me on the phone just now? Thank you, I will take care of the next thing!" The technician said when he saw Cheng Wen.

"Yes, there is no problem. Just now, a service did not start. I also found a bug and it has been fixed. If there are no other accidents, there should be no problems. You can take a look." Cheng Wen said, Because he sees that test case is now all healthy green.

After the technicians took over, they took a look at their services and found that they were all started.

Then I also looked at their functions, tested the main process, and found that there is no problem.

Next, he found the bug that Cheng Wen had just modified, and was going to study it to see how Cheng Wen fixed it.

After looking at it carefully, he also thought about it, and found that this problem is not inevitable, but only encountered in some special occasions, and Cheng Wen's solution is also very simple.

In fact, this problem is mainly to find where there is a problem, and there are many ways to solve it.

After testing again and again, the technicians did not find other problems.

"Could it be that in such a short period of time, the expert in front of him started the service and also fixed the bugs in the code by the way?"

"Where did the crossing dragon come from, it's so powerful?" The technician looked in Cheng Wen's direction, with many question marks in his heart.

At the same time, a legendary term came to mind in his mind - "Ten Times Engineer".
