One dollar start: Do you know what a business genius is?

Inside the office.

Lin Yi is typing the code.

He plans to move the website directly to the APP on the mobile phone.

After all, college students nowadays still prefer mobile phones, which are convenient and fast.

When Lin Yi typed the code, he was also waiting for the arrival of midnight.

Another sleepless night is doomed.

Almost all the students are waiting in front of the computer.

The hour of zero came quietly.

Liang Kexin stood in front of the computer, nervously paying attention to the capacity of the entire server!
Lin Yi is busy with coding in the office.

"Do you think this time will cause the entire server to crash like the last registration?"

Liang Kexin didn't understand these things at all.

But all these people in front of her didn't quite understand.

After all, in the whole team, only Lin Yi understands the computer problems.

Liu Rongyi touched his chin, and pondered a little: "No way, how big is the server capacity when you registered, and now there are only 5 people, how could it be overwhelmed, and it's just a matter of a moment, the problem should be not very big!"

"I hope, but if Lin Yi doesn't look at it, he always feels a little worried in his heart!"

For some reason, Liang Kexin felt a little worried.

"It's okay, can't we see the load capacity of the server here? When it breaks through 80.00%, we'll go in and call him okay!"

Liu Rongyi felt nothing, and quickly came up with a solution.

Everyone was really bored, so they ordered another wave of supper at night and sat down to eat.

Time passed by every minute.

Soon it was eleven fifty.

It's 10 minutes to midnight!

Liang Kexin put away the playful attitude just now, and his expression became tense in an instant.

But at this time, the capacity of the entire server soared to 70%!

"Such a large carrying capacity?"

Liu Rongyi looked at the words 70 that had turned yellow.

This is the program written by Lin Yi.

When the carrying capacity directly exceeds the 80.00% alert!
The whole figure will be colored red!

At this time, no matter what, no matter what Lin Yi does, he must be notified!
80.00% load.

A little more, and there may be a server downtime, which will completely cause a 404 on the page.

"Isn't that going to be a problem?"

Liang Kexin's whole expression became tense, and she felt a little uncertain for a moment.

"There shouldn't be any problem. Didn't Lin Yi say that at the very beginning, there will indeed be a lot of people coming in, because everyone is constantly refreshing the webpage, so there will be a lot of load!"

Liu Rongyi is relatively old here, so he came to make up his mind!

"Besides, it's not yet the 80.00% warning line, so don't worry!"

Liu Rongyi comforted him, but his frowning betrayed his inner thoughts.

In fact, Liu Rongyi has no idea in his heart.

Good guy.

After breaking through [-], I didn't have any thought of stopping at this point, and I was still constantly improving.

"Hurry up, hurry up and call out Lin Yi now!"

Liu Rongyi stared at the rapidly rising data.

Although he doesn't know much about the things inside the computer.

But he understands math, he understands data.

When growth does not have any intention of slowing down, breaking the alarm is only a matter of time.

Lin Yi, who was typing the code, was directly called out by Liang Kexin.

"Mr. Lin, our server capacity is not enough!"

Liang Kexin didn't care so much, and went straight to the point.

"Impossible, how could our servers not hold up?"

Lin Yi scratched his head, walked out of the room, and came to the computer outside.

When he saw the scarlet number 83, he was also resolutely silent.

Almost instantly, his hands operated the keyboard, as if he was playing a beautiful piano piece.

Not long after, Lin Yi opened the shell terminal of the server and quickly typed codes in it.

After a while, Lin Yi's expression gradually became serious.

"Someone wants to attack us with a virus!"

Lin Yi frowned and said: "These people want to take advantage of the ten minutes before the lottery draw, everyone will open the refresh page to place worms, and gradually start to multiply, and all these viruses use refresh codes! "

"The refresh codes are hidden inside, and ordinary computer programmers may not be able to detect them."

"After all, the entire server is now up and down, all of which are refresh requests!"

Lin Yi briefly introduced, while quickly operating with both hands.

"Then is there any way to find out? Is the problem serious?"

Hearing that a virus had invaded, Liang Kexin and the others' faces were filled with solemnity.

They are completely laymen.

In their memory, they only heard about burning incense pandas, and once these viruses invaded, it would be a destructive blow!
"This thing is not difficult, but from a technical point of view, it is difficult to find them, because you can't tell whether these refresh requests are page refresh requests generated by normal browsing, or malicious refresh requests, after all, the requests are the same! "

Lin Yi operated with both hands while chatting calmly.

For the server background, the request is the same.

It's like, when you hear a knock on the door, you know that someone outside has issued a request to open the door, but you don't know who it is!

Same thing.

"It can't be judged through the program? Is there any effective way?"

Yang Qingxue had studied computers when she was in college.

She knows that no matter how powerful the current artificial intelligence is, it is all program code in the final analysis.

If it is not possible to write a procedural judgment, is it necessary to make a manual judgment?

"That's not what I mean. I'm just saying that it can't be detected from the program, but it can be accurately judged from the time interval."

"It's very simple. If it's a normal person, after they log in to the page, they won't keep refreshing, so the interval between them should be at least 1 minute!"

"Only when it is close to twelve o'clock, they can refresh quickly, but these viruses are not like this. They replicate quickly, and then quickly start refreshing with script files, so that they can cause the server to crash!"

When Lin Yi said this, he suddenly pressed the ENTER button with his right hand.

"Clap!"

The crisp keyboard sound fell, and Lin Yi looked up at the crowd.

"All right!"

When Lin Yi said these two words, lines of code appeared in front of Lin Yi's computer keyboard, and they quickly rolled over.

This is a virus killing program.
