Chapter 199: Luck and Misfortune Ask for a monthly pass at the end of the month

After Lin Hong stayed in Arthur's room for a while, he returned to his room. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info ("" network 7 * 24 hours uninterrupted update pure txt hand-typed novel) the other party is reinstalling the system, and then recovering the data on the hard disk, which is a very boring process, very time-consuming.

It seems that Arthur has a hard time resting tonight, it was already two o'clock when he was poisoned, and if he tossed like this, he couldn't do it at all until five or six o'clock.

Lin Hong returned to the room, he wanted to study this virus carefully, but he didn't know where to start, he didn't know much about this part, he was poisoned by the "monkey" virus before, and Arthur helped recover it.

This time the April Fool's Day virus actually made the other six members of the SAM Association recruited, and they are all people with a very good technical foundation, which cannot but be said to be a great irony.

At the same time, this also shows a problem, that is, everyone's awareness of computer virus prevention is still very weak, even for people who understand technology, let alone those ordinary users.

Moreover, this time, Lin Hong deeply experienced the powerful power of the so-called "social engineering".

When Kevin told him about it before, he didn't think it was anything powerful at all. Psychological weakness? Lin Hong doesn't think that he has such a weakness, he thinks that he is calm enough and steady enough to do things, and it is not easy for others to find their weaknesses.

But it turns out that everyone's psychological defenses are fragile, including him. A simple email can directly get them all done.

Is this a weakness of the mind?

Maybe it's not a weakness of the heart, it's just taking advantage of everyone's trust in their friends, this is a subconscious, for people they are familiar with, they will not be defensive, because long-term experience tells themselves that the other party is credible, so the email he sent is also credible, this is an extremely simple thinking inertia.

But, on the other hand, this is indeed a weakness of the mind.

People who are good at taking advantage of this mental inertia, or mental law, are often able to answer their goals very easily. (《》网)

Kevin is one such person. He has the same ability as Lin Hong, and can roughly perceive the emotions of the other party, so he can adjust his strategy in a targeted manner, so that he can gain the trust of the other party or let others follow his instructions.

In fact, Lin Hong involuntarily took advantage of his talent many times. For example, when negotiating with Joseph White, he can talk freely with the other party at the negotiating table, relying on his own ability.

Time passed in Lin Hong's thoughts, and the window had begun to glow, and a new day had come.

Lin Hong went out for morning exercise again rain or shine.

Today, both Arthur and Matthew are absent.

As you can imagine, both of them must have been busy restoring their systems last night.

After returning from morning exercise, Lin Hong saw Arthur, whose eyes were bloodshot dissatisfied, yawning and coming down from upstairs, and his whole person was haggard.

"Oh, Arthur, what's wrong with you?" Vina came out of the kitchen with cereal porridge, and when she saw her son like this, she was immediately distressed.

"Well, I had insomnia last night." Arthur yawned again, then walked into the bathroom and began to wash up.

"Stone, is Arthur okay?" Vena came to Lin Hong's side, looked at the bathroom, and asked in a mysterious whisper.

"It should be fine." Lin Hong was a little surprised by Vina's expression, "Maybe it was because I didn't sleep well yesterday." ”

"Not a broken love?"

"Uh......" Lin Hong was stunned for a long time when he heard this, "Lost love? ”

"It's with Joanna! He looks like this, like the state when he is out of love, you tell me honestly, is he out of love? ”

"It's not." Lin Hong shook his head.

Although he didn't know exactly what Arthur and Joanna were like. However, for today's situation, he can be sure that it is definitely not because of broken love.

"It's good if it's not a broken love, that's good." With a relieved face, Vina continued to go back to the kitchen to serve breakfast.

Lin Hong felt that Vena's personality was very funny, and he actually hoped to have such a lively mother. It's a pity that the chat atmosphere between him and his mother really can't become lively, although he wants to, but he can't do it.

When Lin Hong and Arthur arrived at the school, Matthew and Pissen were already waiting there in the locker area.

It can be seen that the two of them are not in good spirits, and their eyeballs are not bloodshot, which is obviously caused by lack of sleep last night.

"You two, you're only here now." Matthew said listlessly.

"It's still early, right?" Lin Hong was a little strange.

"It's still early? Didn't we just say yesterday that today we have to come over early and set up the scene? ”

"Uh...... Is there such a thing? How did I not know? ”

"I forgot to tell you when you came back yesterday." Arthur then interjected, "You weren't there when we were discussing. ”

Matthew yawned: "Fortunately, the two of us have already put up the poster, otherwise because of the virus, even the major events of our association would have been delayed." ”

"I'm sorry, I don't know when that virus was hit." Pissen apologized with some embarrassment. Everyone was poisoned because of his email.

"How's your doing? Is the hard drive also formatted? Arthur asked.

"Speaking of this, I'm very angry." Matthew said with some annoyance, "This April Fool's Day virus looks like it formatted the hard drive, but in fact it just modifies the partition table of the operating system, creating the illusion that the hard drive is being formatted!" ”

Arthur's face turned blue when he heard this: "How do you know? ”

"When I was in the activity room today, I went to the forum to take a look, and there are many people discussing this matter, this April Fool's virus is a new music virus, I don't know which bastard did the prank, it didn't actually destroy the data on the hard drive, just fix the partition table."

“**!” Arthur couldn't help but burst into a foul mouth, "Yesterday I got it until five o'clock this morning in order to recover my data!" I also wonder why the data recovery went so smoothly this time! ”

"You're lucky." Matthew said helplessly, "Both Pissen and I reformatted the hard drive, and all the data was gone. ”

Pissen also showed a sad look at this time. As a tech nerd, he has stored a lot of good things on his hard drive, which he has accumulated for several years, but just yesterday, these things were removed by his own hands, and they can't be recovered at all.

When they arrived at school today, many people made fun of the two of them, but they didn't have the heart to give the slightest reaction, and both of them were depressed.

There were still more than ten minutes before the start of class, and the three of them quickly ran to the cafeteria to take a look, and found that it was already full of classmates, some of them were standing there looking at the posters that Matthew and Pierson had put on the wall early in the morning, while others raised their calculators and began to receive the cracks on it and upgrade them.

They watched from a distance for a while before leaving.

Overall, the effect is still good, everyone's enthusiasm for this upgrade activity is okay, and then it depends on whether the future development can be carried out as planned.

Lin Hong's first class was mathematics, and even during class, the classmates sitting next to him privately asked him if he had turned on the infrared transmission function of the calculator, and he wanted to crack it. Lin Hong had no choice but to take out the calculator and turn on the function of sending signals to the outside world, so many boys around him immediately took out their calculators to receive them, and then cracked them.

This caused a small commotion, which ended up attracting the attention of math teacher David.

Lin Hong secretly said badly, before he could put the calculator away, David had already walked over to this side.

He walked up to Lin Hong, took the calculator he had placed on the desk in his hand, and then operated it for a while.

"That's good! Is this calculator the one that your SAM Association has remodeled? ”

"Yes." Seeing that he was not angry, Lin Hong also calmed down.

At the beginning, he was really a little worried, after all, this was also a disruption of the classroom order, and if it was in China, the calculator would definitely be confiscated by the teacher. But on second thought, this is the United States, and it seems that this rarely happens.

At this time, in Lin Hong's surprised eyes, David also took out a calculator from his suit pocket, pressed the receive button on Lin Hong's, and began to crack.

Everyone burst into laughter.

Lin Hong didn't expect that David would also know that they were going to release a cracked program today.

After cracking it, he called up the synchronization program inside, received two small programs from Lin Hong's calculator, and found that the volume was indeed much smaller than before, and couldn't help but nod with satisfaction.

“nicejob! (Great job)" David praised.

"Thank you!"

"I want you to help me revamp this calculator too, I don't know how much I need to pay you?"

Lin Hong originally wanted to tell him to give him a free transformation directly, but he thought that the association belonged to everyone after all, and since other people needed to pay a certain fee for upgrading, the teacher was naturally no exception. So he said, "Thirty dollars." ”

David nodded, indicating that he could accept it.

Then, he raised the calculator in his hand and said, "Stone, I would like to ask you to tell us about the math involved in this compression algorithm, can you?" I think other students are also very interested in this. Do you think so? ”

"David was right!"

"Tell us about it."

"We're really curious about the algorithm!"

……

Everyone chimed in.

Lin Hong hesitated for a moment, but finally nodded: "OK." ”

So, Lin Hong forcibly overcame the rejection of this kind of scene in his heart, stepped onto the podium step by step, and explained the basic principles of the pkzip compression algorithm to the students on the podium for the first time like a teacher.
