Hammer of Technology

Because in Ningwei's conception, these things are not simply added, but are perfectly integrated with the functions realized by the turbulence algorithm itself. If you want to remove any piece of code, it may cause various problems in the entire software itself. problem, so that even if it is discovered that there may be a problem, if you want to get rid of these codes, you need to spend several times the energy to repair the entire system.

But this is also a big project for Ningwei, and it will take at least a week to complete.

After being given a thought lesson by a math boss from the other side of the ocean, Ning Wei's thoughts inevitably began to move towards a darker path, even if it was just for self-protection.

Turning off the computer, Ning Wei glanced at Sanyue, then stretched, "Ah..." yawned long...

Then he saw Sanyue on the screen, and stretched out his two small front paws, imitating him: "Oh..."

"Just your skin! Come on, call Dad and listen!"

"aim……"

"I don't care about you! Sleep!"

……

In the next week, Ning Wei began to retreat and reorganize the source code of the turbulence algorithm.

It's really a retreat. In order to perfectly embed the reserved small means into the original code, it is not much less difficult than typing the code directly.

It took Ning Wei half a month to change the turbulence algorithm from a vague idea in his brain to an executable program, and he worked more than ten hours a day; and to modify these codes, he spent a full six days, also working more than ten hours a day Hour.

After completing this work, Ning Wei even felt very excited.

Really, he really hopes that someone will pirate the turbulence algorithm for profit without his permission, take a bite out of this cake, and teach him how to be a human being.He even couldn't wait to prepare the paper with all the codes and submit it.

During this period, the laboratory also came forward and began to help Ningwei to contact the real environment for the public testing of the turbulence algorithm.

Because Ningwei hopes that the public beta stage can directly face the most end consumers, so the most ideal environment is naturally the domestic 12306 ticketing system.

After all, this is arguably the most complex and most visited ticketing system in the world.

It is estimated that the official itself is too lazy to count how many times it is patronized by various crawlers every minute during the peak ticket sales period, especially those popular train tickets connecting China's wealthiest super cities.

For this matter, Lu Changbin personally went to the capital, found connections and invited Mr. Tie's people to dinner.

Of course, in the end there was no surprise rejection.

It's not entirely because Lu Changbin's face is not enough.

Mr. Tie has a good reason.

For such a Big Mac ticketing system for the people of the whole country, stable operation is the most important thing, even if some of the fairness that should have been sacrificed in order to achieve this.

In other words, they really dare not use the turbulence algorithm, which has only been tested in the laboratory, even though Ning Wei has been on the stage of the world's top computer algorithm conference because of this algorithm.

Of course, it's not completely useless.

The leader in charge of this matter promised Lu Changbin that if the final test is stable and proves that this thing is indeed useful, 12306 will definitely support this domestic software product without hesitation.

Although Boss Tie didn't get it done, Lu Changbin was not without gains.

Directly negotiated a cooperation plan with two small airlines, Chunqiu and Dongxing.Specifically, people from the laboratory will cooperate with the website maintenance personnel of the two airlines to upgrade the entire ticketing system, and provide free training for the website maintenance personnel to conduct software testing.If it is really stable and effective, and the testing phase satisfies the two airlines, the two airlines can use the turbulence algorithm for free for five years in the future.

Of course, if the software itself causes irreparable and major losses to the airline due to software defects or loopholes during the testing phase, the laboratory must not only assist the airline to restore the ticketing system to its original state, but also need to pay certain compensation according to the agreement.

This item was added by Lu Changbin on his own initiative, not only because of his absolute trust in Ningwei, he has personally studied all the update iteration records of the turbulence algorithm and laboratory test records, and simulated the airline's ticketing system in the laboratory, and carried out The preliminary turbulence algorithm protective test, finally came to the conclusion that the algorithm has always been stable, this is his confidence.

In addition to the two airline companies that Lu Changbin took the initiative to visit, there is also a relatively well-known domestic ticketing company that took the initiative to approach Lu Changbin, hoping to test the turbulence algorithm.

Lu Changbin did a general search. This company is mainly engaged in the service business of Chinese domestic stars' concerts, and provides one-stop services for stars' concerts, starting with helping with approval, planning, publicity, and final ticket sales.

In the words of the owner of the performing arts service company, scalpers robbing tickets for popular star concerts and selling them at high prices made him miserable.

The money company from the scalpers didn’t make a lot of money, and they were accused by many fans who couldn’t buy or were forced to buy high-priced tickets for colluding with others to drive up ticket prices through scalpers.

If it weren't for the same problems faced by the peers, this word of mouth would really be ruined.But because this company is well-known and can get more popular resources, it is naturally scolded the most in the fan circle.

So after learning that the technology being promoted by Jiang University can effectively prevent scalpers from grabbing tickets, they immediately asked someone to find Lu Changbin, hoping to experience it first, and promised that as long as the test effect is good, how much money will be paid? Money has to be bought and used.

Especially recently, there happened to be two veteran star concerts with many fans in preparation, and after perfecting their own ticketing system, they could start testing the effect immediately.

The boss even said at the dinner table that if he tried the turbulence algorithm this time and it still doesn’t work, he has already started to consider giving up the ticket sales system that he built himself at a huge cost, and directly subcontract the online ticket sales to other professional ticket sales networks.

Although it is still unavoidable for scalpers to grab tickets, at least the company no longer needs to be scolded.

After Lu Changbin made a phone call and discussed with Ning Wei, he decided to accept the order.

In addition, Jiangcheng has cooperated with Jiangda or coordinated with the relevant higher-level departments, and there are also units with similar needs, such as the registration system of Jiangda Affiliated Hospital. A total of seven realistic test scenarios have been found for the turbulence algorithm test.

It is also sufficient for the public beta of the turbulence algorithm.

This is also the reason why Ningwei shut himself in the laboratory and ignored almost everything, and has been working hard to modify the source code.

Starting from being used for testing, it must be the source code with added materials, and the outside world is not given any chance to obtain the original source code.

The next thing is Yu Xingwei.

As one of the project team members who know the turbulence algorithm best and is most trusted by Ning Wei, the next job is to bring seven master students who have received a week of training to deploy to the ticketing websites or official websites of several companies that have signed testing contracts Turbulence algorithm.

Ning Wei's momentum in soda in the early stage, coupled with this time Lu Changbin was looking for people to test everywhere, naturally attracted the attention of countless people, and even many related industries have begun to focus on this test.

Even many companies that specialize in ticket grabbing services have received many alternative tasks entrusted by customers.

"Have you heard of the turbulence algorithm? After the official launch, focus on the two airlines and try it out. If you can break through the algorithm and grab tickets in batches, the price is easy to say."

------------

123 I'm here to send warmth

After Yu Xingwei paid the price of losing weight in a week, all the test environments required by the first batch of companies that signed the test agreement were finally deployed and passed the pre-test.

To be honest, Yu Xingwei worked really hard to do this.

Deploying a security defense software in a real-world scenario is not as easy as it is in a laboratory environment.Because the environment faced is more complex, problems that have not been encountered in the laboratory may arise at any time during the deployment process.

Fortunately, Yu Xingwei, a Ph.D., really didn't come out of nowhere. Basically, he was able to find the cause of the problem independently. If it was really impossible to solve it, it wouldn't waste much time if he called back to the laboratory and worked together.

After the deployment is completed and the environment is debugged, the final public test time of the turbulence algorithm is set at 3:15 pm on March [-].

In fact, it can be moved two days earlier, but Lu Changbin specially chose this day. The reason he gave was to make this day more memorable. On 315, a special annual day, he helped consumers protect their rights in another way. This intention immediately became much taller.

Then Lu Changbin hurriedly finished the work at hand on March 3, and flew directly to the capital. At noon the next day, he visited the information security laboratory under the Chinese Academy of Sciences, and asked his old alumnus He Dushang to treat him to a meal.

I usually play for fun, and make trouble for me. If I really come to visit, I still have to be entertained.

During the banquet, after drinking a glass of wine, Lu Changbin started his performance very sincerely.

"Let me tell you, Lao He, this is the relationship between our two alumni, otherwise this good thing will not be your turn. Our laboratory has specially prepared 200 million cash, which is to be used. I and the laboratory The greetings have already been made, and the news of the official public beta will be released at 02:30, and I will give you half an hour to study how to break through this line of defense."

"Let your boys work hard. This time I'm giving you bonuses in a serious manner. The rules are very simple. You can grab tickets worth how much money you have through technical means. Add one plus. Just add two zeros at the end, and send it to you as a bonus, you don’t have to worry about taxes, it’s all paid in real time. Oh, by the way, let your favorite student Xiao Cao have to go to the battle in person, the fat will not flow to outsiders’ fields Well."

Look at what he said, He Dushang probably wouldn't believe a word of it.

Of course, the information disclosed in this is very important.

He Dushang stared at Lu Changbin and asked, "Old Lu, do you really have so much confidence in this turbulence algorithm? Don't you be afraid that if you play too big, the boat will capsize in the gutter, and you won't be able to end it in the end?"

Hearing this, Lu Changbin was obviously unhappy, and said, "He Dushang, is it boring for you to say that? I admit that we have been fighting for most of our lives, but when it comes to you, is the relationship lost? No Who can be [-]% sure of a product that has undergone actual large-scale testing? Do you have it? I have come all the way to give you a big favor. Is that why you think of me?"

This seems to make sense.

Everyone is in this business. No matter how confident you are in something that just came out of the laboratory, it is difficult to guarantee that there will be no problems in the actual testing process.

After all, the complexity that the real environment needs to face is far beyond what a simple laboratory environment can match.

Not to mention that the official public beta means that the turbulence algorithm has to accept the challenges of countless masters.

In the past, those laboratory products that blown their own security systems to the point of explosion were confidently sent to the White Hat Conference for testing, and the results were directly attacked as leaky sieves abound.

There was even a joke that a product that claimed to be the world's first integrated smart security certification system was given the highest authority by a top domestic team in less than a minute.

Lu Changbin is no longer a newcomer in the industry, so he should not make such a mistake.

So Lao Lu really changed his gender this time?Thinking about it this way, I suddenly feel a little guilty. After all, I am an alumnus. If anything happens, I still have to help each other.

Then he, He Dushang, shouldn't be too stingy, because he was underestimated by this guy for no reason.

Thinking of this, He Dusang said grandly: "Okay, I believe you, I have to keep an eye on you in the afternoon so I can't drink with you, so you can drink a couple of glasses by yourself at noon, anyway, I will hand it over to those boys in the afternoon. Don't drink too This is wine. My nephew went out for a business visit a few days ago and knew that I usually like to drink some wine. When he came back, he brought me a bottle of limited edition wine from France, which is said to be produced by the top winery there. It costs several thousand. One bottle, I lost it in the office and was reluctant to drink it, so I opened it for you today! Xiao Chen, go to the cabinet under my office and get that bottle of wine back."

"Okay, boss!"

Lu Changbin smiled happily and said, "Haha, this is a good alumnus! Come on, I won't drink this wine for now, let's eat vegetables, eat vegetables!"

"How about two more dishes?"

"Okay!"

……

The time came to six o'clock in the afternoon...

He Dushang's face turned blue.

80.00% of the technical backbones of the entire laboratory were mobilized and went into battle. They were divided into three groups to focus on two special airlines and the concert ticketing system. As a result, four hours passed and no tickets were obtained through technical means.

What's even more ironic is that, out of boredom, two young men in the laboratory manually snatched up two special airline tickets that were specially sold by the airline for this public test.

You must know that in order to maximize the benefits, the three groups are directly aiming at those regular-priced air tickets that no one is grabbing to go to the high-priced tickets in the VIP area of ​​​​the concert.Now the special airline tickets issued by the airlines are sold out, and the concert tickets are almost sold out, but they have nothing.

Judging from the rules formulated by Lu Changbin, they can continue to find ways to use various technical means to dig out those regular-priced airline tickets, but He Dushang understands that it is meaningless.

The boy in the laboratory can buy a special ticket through normal means, which is enough to explain a lot of things.

He knew very well that his laboratory was definitely not the only one staring at the public test of the turbulence algorithm.

"Well, Lao He, what time do you have dinner here tonight? I feel a little hungry. After we have had a good drink tonight, it's time to say goodbye. But don't worry, our agreement is valid within three days. You only need to Show proof that the ticket was indeed obtained through technical means, and we will make the payment immediately." Lu Changbin patted his chest and promised sincerely.

He Dusing took a look at the expensive red wine that had been drunk by a third, and his heart was no longer bleeding, but spurting blood.

Feelings, he mobilized a group of backbones in the laboratory to help the guy in front of him do the test with all his heart and soul for an afternoon. Not to mention that he didn't get a penny, and he even bought a bottle of red wine that he couldn't bear to drink.

These are actually nothing, and more importantly, he was directly shown face to face by Lu Changbin.Thinking of this, he felt that his blood pressure was soaring, and the back of his head was aching...

But at this time, he really can't get angry.

Because people outside the industry may not understand the meaning of the turbulence algorithm, but he understands it very well.

"Hehe... Don't worry, there will definitely be dinner, the highest standard, but there is one thing you need to tell me first, I heard that the turbulence algorithm was independently completed by that young man named Ning Wei? Is it true? ?”

"Haha, what's the point of talking about this now? Let's go, let's chat while eating! As long as you, Lao He, will be interesting enough, I know everything I can say, and I can talk endlessly!"

……

These four hours are definitely not just the four hours when He Dusang's heart is bleeding.

In fact, there are many people who help Ningwei do the test for free, and it is definitely not just the laboratory.

There are more people watching this public beta.

Some of them can get the first-hand data and start analysis directly, such as the Internet giants who provide cloud services for the sales websites of these public beta companies.

More people can analyze the situation by what they can see.

For example, the special tickets of the airlines. In order to cooperate with this test, the two airlines released 72 special tickets at one time, involving a total of 22 flights that will be operated in the next two weeks.

This is the first time that the special ticket has lasted for such a long time on the official ticket sales network.

It used to be Miaokong, but this time it lasted for 10 minutes before being robbed.

After half an hour, the system automatically released 69 special tickets.

That is to say, except for three real-name payments, all others were returned due to overtime payment.

You can probably imagine what this is about.

Then, more than ten minutes later, these special tickets were emptied again, and half an hour later, 62 tickets were returned again...

In this way, at night, there were actually 43 special tickets to less popular areas listed on the official website, waiting to be purchased.

But this time the ticket has already been thrown there, and no one is grabbing it.

After all, for the scalpers of the airline company, if the process of ticket grabbing, release, and ticket grabbing cannot be automated by machines, it is meaningless to them.Could it be that a few people are invited to grab it manually?Leaving aside the efficiency, the labor cost is there now.

Who wants to sit in front of the computer 24 hours a day and refresh one by one in front of the computer?

This means that the two airlines cooperate with the algorithm public test to release so many special tickets at one time. Most of the time, low-cost airlines release special tickets in small batches, and the distribution time is random, and most of the time is selected in the middle of the night.

If you rely on people to rob it, you have to rob it again every half an hour. If you forget it, it may be bought by others. How can this business be done?

So the scalpers are too lazy to do it. If you have this spare time, it is better to find someone to help them upgrade the software.

Of course, apart from Spring and East Star, the software is still very useful for grabbing tickets from other airlines.

For those technicians who choose to actively help the turbulence algorithm to test for various purposes, they naturally don't need to manually grab tickets, and they don't even need to focus on those special tickets. They only need to use the existing If the advanced technology can bypass the defense of the turbulence algorithm and directly grab the tickets, it is a victory.
