86. Neon Forty-Three
The next day, Sunday morning.
I got on the bus with Incheol.
“Why did you bring all the bags?”
I said to Incheol’s question.
“I just brought it.”
“When you come to the office, you come without a bag. Perhaps… Did you bring some delicious snacks?”
“haha–! It’s not like that.”
Incheol opened his eyes and looked at me and said.
“Hmm… Are you somehow suspicious?”
Also, In-cheol is quick-witted.
In this case, you need to be more cautious.
“Am I a spy? What is the award? men and horses! It’s only natural for students to carry their backpacks!”
Yoon Sung Soft.
When In-cheol and I arrived at the office, Yun-seok-yi hyung and Eun-seong were already waiting for us.
After a short greeting, Yoon Seok-yi hyung said.
“finally… .”
“… ?”
Yoon Seok-yi hyung raised the corners of his twitching lips and continued.
“I signed a contract with the Ministry of Public Administration and Security!”
“Wow! Really?”
The missing child search program, which has been talked about and ridden a lot, is now being released to police stations and government agencies across the country.
In response to In-cheol’s question, Yoon-seok-hyung nodded and said.
“The terms of the contract are very good. It’s a five-year contract, and I think we can hire an employee who is exclusively dedicated to the missing child program.”
“president! So, shouldn’t we have to move our office?”
These were words mixed with In-cheol’s jokes.
Although the office of Yunseong Soft is not very large, it is a space that can work together for up to 5 people.
But Yoon Seok-yi hyung’s serious answer came back.
“I don’t think so.”
“Really?”
“Yeah, now V-Stop is no joke. Every time I check the number of V-Stop downloads, I’m amazed. The effect of data field advertising was really great.”
For reference, the first V-Stop was launched two years ago, and the advertisements in Datafield started three days ago. Says
Yoon-seok-hyung continued speaking in a slightly excited voice.
“Until now, this assistant and I were managing the V-Stop feedback data, but now we have another employee, so that this assistant and a new employee will be in charge of V-Stop.”
“Then what will you do?”
In response to Eun-seong’s indifferent voice, Yoon Seok-yi hyung said with a serious expression.
“I’m going to focus on Jungho, Incheol, and Michael Security now. Michael Security seems to be very busy.”
“… ?”
“I don’t think it’s a joke about CEO Jung’s personal connections. With the introduction of President Jung, three meetings were held next week regarding the contract with Michael Security.”
Yoon Seok-yi hyung made eye contact with me and said with a smirk.
“Now the water is coming in, you have to paddle.”
In the meantime, Yoon Seok-hyung had not expressed his feelings, but I was well aware that he was very nervous.
This is because, while V-Stop’s sales increased little by little, Michael Security did not have a single additional contract for two years after the contract with the Seoul Metropolitan Police Agency.
I nodded my head towards Yoon-seok-hyung and said.
“It should be! You have to stir hard! There was one feature I wanted to add to Michael Security, and the timing is good.”
“Five… ! okay?”
“Yes, I will explain the details later.”
“president!”
Incheol continued counting with his fingers.
“You’re saying we’re going to pick two more people soon, so will we be seven?”
“right!”
“Oh my! So, are we going to give Jeong-ho a rinse?”
I covered Incheol’s mouth and said.
“Ugh! That bastard’s Henggarae Taryeong! Stop it now, man!”
At my words, Yoon Seok-yi hyung said.
“why? I was thinking the same thing?”
“Put me in too. Then there are eight.”
it was silver
“under—-! Why are you like this too, Eunseong-ah! Aww—!”
A burst of laughter erupted, and Yunseok-hyung opened his mouth.
“Shall we have lunch now?”
It was a Sunday, so I had a late breakfast, and I wasn’t hungry yet.
But looking at his face… .
Eunseong and Incheol have similar eyes.
“Boss, the rice is ready, how about sundae and tteokbokki?”
At Incheol’s words, Yunseoki hyung said.
“A snack bar in front of the bus stop?”
“Yeah, I just smelled the sundae on my way to the office.”
“Then shall we eat sundae, tteokbokki, and convenience store chicken gangjeong and frozen dumplings together?”
“Five! good!”
So, when Yunseok hyung and Incheol left the office to buy food, I opened the bag and took out a thick notebook.
Then he picked up the stiff paper that was stuck between the notes and held it out to Eunseong.
“I… Eunseong-ah.”
“yes?”
“I am here… May I ask for the Silver Castle autograph?”
Eunseong smiled broadly and nodded, and I opened my mouth carefully.
“Actually, this… It’s someone else’s request, okay?”
“Others? yes I’m fine. It must have already surpassed 100 copies just for what my hyung asked for?”
Eunseong opened the cover of the name pen and continued.
“By the way, what is the name of the person who asked for an autograph?”
“name? name is… Jung Myung-soo.”
“Are you friends?”
I shook my head and said.
“Not friends… .”
As I blurted out the end of my words, Eunseong said with a curious expression.
“Then who are you?”
President Jung asked Yoon Seok to get an autograph without his brother’s knowledge.
“just… He’s like an uncle.”
Eunseong made a nice autograph starting with ‘To Myeong-soo Jeong’ with skillful hand movements.
“Wow! Thank you so much, Eunseong-ah!”
I took the signed paper and carefully put it in my bag, and just as the office door opened, Yoon Seok-yi hyung and In-cheol came in.
“I bought a snack!”
We sat around the table and started filling our stomachs.
“Did you guys take the mock exam yesterday?”
In response to Yoon-seok-hyung’s question, In-cheol filled his mouth with sundae and nodded his head.
“Incheol-ah, do you think you will exceed the 370 points you promised?”
Incheol said as he swallowed the food.
“Of course, boss!”
By the way… Didn’t Incheol yesterday say that the exam was difficult?
This time Eunseong said to Incheol.
“In-cheol, why are you going to the Japanese language department?”
“I want to watch Japanese manga!”
“Isn’t that a joke?”
“I’m not kidding… .”
Eun-seong opened his eyes at In-cheol’s serious expression and said.
“Who in the world chooses a major for that reason?”
Incheol said, pointing to himself with both hands.
“You are here.”
“a! don’t do that, tell me What is the real reason you want to go to the Japanese language department?”
“It’s true… Why don’t you believe me?”
In-cheol’s clever expression.
In-cheol won’t tell you the real reason.
Four days ago, I had the same conversation with Incheol.
I was teaching the rejection function to break the RSA code, and even when I threatened not to tell you how to calculate the rejection function, Incheol did not tell me why she chose the Japanese language course.
As if to change the topic in response to Eun-seong’s persistent question, In-cheol looked at me and continued.
“I am learning math from Jung-ho these days. That’s right, is it Jeongho?”
I nodded, and Incheol continued.
“After learning, math was also very interesting. So now I am seriously considering whether to go to the math department.”
It is true that Incheol has a quick understanding of mathematics.
I quickly understood the basic concepts of set theory and algebra.
But is it possible for In-cheol, who is a liberal arts major, to apply to the mathematics department?
Anyway, the interest in the story shifted to me as In-cheol intended, and he opened his mouth as if he remembered Yun-seok-hyung.
“Jeong-ho, you promised to get over 375 this time.”
“ah… ! Don’t worry about it.”
As Yoon Seok answered his brother, a happy smile spread across his face without realizing it, because he remembered a kiss with Yeongmi at Namseocheon last night.
“By the way, looking at Jung-ho’s expression, it seems that he did really well in the mock test, right?”
At Eunseong’s words, Yunseoki hyung said.
“Five… ! Really! Just looking at his face, he seems to have scored out of 400. Wasn’t he the first place in the country?”
“ha ha ha–! It’s not like that.”
In-cheol said at my words.
“Chae Jeong-ho, this kid is more than the number one in the country! eww—-! You monstrous bastard!”
It was four days ago.
I explained the rejection function to In-cheol for a long time, and when my explanation was finished, In-cheol opened his mouth.
“So! Do you mean that we need to check if the rejected function value is correct?”
“right!”
“And to confirm, you have to compare them with the non-name zero value of the Riemann zeta function, right?”
“yes.”
“By the way, the zero value of the visa name is over 100 million?”
I nodded, and Incheol took a deep breath and raised his voice.
“under—–! Then how the heck are you supposed to check this, bastard!”
Incheol is right.
Since the value of N used in RSA encryption is a very large number, in order to check the value of the Euler pi function of the value of N, it is necessary to compare it with the non-obvious zero value of approximately 100 digits including the number after the decimal point.
For reference, when a number is stored on a computer disk, it is stored in a binary number, that is, in bits, and 2 to the 10th power is 1024, so 10 bits cover approximately 3 decimal places.
That is, to store one 100-digit non-name zero value, 3 x 100 = 300 bits or 37.5 bytes of storage space, and to store 100 million non-name zero values, 3.75 GB of storage space is required. .
As of 1999, the capacity of a modern hard disk is 6.4 GB.
That is, it is not impossible to store the non-name zero value obtained so far on a single hard disk.
But with 3.75GB of storage space filled with numbers, searching for 100-digit numbers will take more time than you think.
Of course, I haven’t tried it myself, so I don’t know how long it will take, but it will probably take quite a while.

Not only this.
To enter and search for a 100-digit number, you have to create a separate program, which is not too cumbersome.
So, the method I devised is to convert the non-name zero value to a base 64 number.
Then, the number of digits of the non-name zero value is reduced from 100 digits to approximately 50 digits, and a much more efficient search becomes possible.
However, since a base-64 number actually uses a character string and requires 8 bits or 1 byte of storage space per digit, the required storage capacity is further increased.
However, if non-announced zero values can be stored in the head instead of on the hard disk, it is of course much more efficient to store them as 64 base numbers with fewer digits.
This is why I converted all non-name zeros to base 64.
In-cheol opened his mouth with a surprised expression at my explanation.
“So… Are you saying that you have memorized all 100 million non-name zero values?”
Mouths wide open, eyes that are wide open, and nostrils that are wide open… .
This is the first time Incheol has seen this expression in the past 6 years.
This expression should be left in a photo… .
a little sad
I said with a smirk.
“Not exactly 100 million, but 125,433,499 right.”
“Chae Jung-ho… I’ve always thought that something was strange, but it was true. You monstrous bastard!”

Two weeks later, Northwest High School.
funeral time.
The homeroom teacher’s hands were full of mock test scores.
“quiet! quiet!”
The hum of the classroom had subsided, but the chatter could still be heard, and the homeroom teacher let out a long sigh.
“under—-! How are you guys so alike? quiet! quiet! Behind it, Park Min-hyuk! Do you want to be handsome? Let’s turn off local TV!”
The classroom finally became quiet, and the teacher opened his mouth with a smile on his face.
“Everyone knows that our school ranked first in the national mock test, right?”
“yes!”
“Our class is number 1 in the country!”
The children banged on the desk and started talking.
“Wow! If it’s the first place in the country, isn’t it the same award from Korea University?”
“You choose the course you want to go to at Hankuk University and go.”
“I still have a lesson I can’t go to.”
“You idiot! Are there any departments that can’t be ranked first in the country?”
“Law Department! We’re science, so we can’t go to law school, right? Isn’t this funny?”
“What’s funny, bastard! Wake up, you’re lazy!”
The homeroom teacher had to sweat again to keep the children quiet, and when the classroom was quiet again, the teacher spoke up.
“The first place in the nation in this mock exam is… .”
