Chapter 44: Vulnerability (4)

The compression algorithm is indeed a very important thing.
Computer technology is now in a stage of explosive development, and the resulting data is also massive, not to mention the endless video and audio files on the Internet.
The effect of the compression algorithm is to encode them according to certain rules, into a form that is easy to transmit and store, and then decode when necessary to restore the original data.
Therefore, an effective and lossless compression algorithm can greatly improve the transmission and storage efficiency of various files, data, and signals. If there is no compression algorithm in the world, the Internet may be paralyzed because it is too bloated.
Such an important algorithmic field, symbolizing the state of Jindan in the cultivation of immortals, seems to be commensurate with its own status.
Lin Xun felt that he had seen the truth.
After about half an hour, the Python platform is loaded.
According to the experience of the last time I was promoted to foundation, Lin Xun spent a long time to realize the basic operations of most object-oriented languages. After pushing the main task progress to 50%, he started to connect to the hard disk The programs collected by security over the years, with various wheels, started to call the forming compression algorithm one by one.
The Huffman coding using the binary tree is very classic, and it is indeed the case. The progress has suddenly increased by 10%.
The LZ series is essential, 5%.
Shannon is the first ancestor, with a significant significance, 5%.
After reviewing history, Lin Xun began to call the mainstream lossy and lossless compression algorithms over the years. Their names are strange and their application fields are different.
The progress bar is slowly rising, and the outlook is promising.
But just when Lin Xun thought he was going to Jindan smoothly, it slammed.
Ninety percent.
Next, no matter how cutting-edge the program is called, the progress bar remains motionless.
After some attempts, Lin Xun was convinced that the remaining 10% must have other keys.
He didn't die with the system, he came out of the space, looked for related papers for a while, and planned to fall asleep.
But he seemed destined to be busy this day. As soon as he held his pointer and closed his eyes, the phone rang, and the caller noted Lin Ting.
Lin Ting, his older sister, three years old, was born.
Lin Xun answered the phone: "Sister."
His sister's voice came from the receiver: "Forget it."
The voice is a bit dumb, not much like her usual tone.
Lin Xun: "Did you catch a cold?"
"A bit." Lin Ting said: "I'll take the plane tomorrow and arrive at the Imperial Capital in the afternoon, pick me up."
Lin Xun: "Okay."
He continued: "You send me the flight number."
"Well." Lin Ting said: "Are you going to sleep?"
Lin Xun: "I'm going to sleep."
His sister laughed: "So early."
Lin Xun: "I don't cultivate immortals anymore."
Lin Ting said: "Then I will hang up first, don't forget to pick me up, I bought you a lot of things."
Lin Xun smiled while holding his phone: "I can't fit my closet."
"The closet space is like water in a sponge, good boy, good night."
Lin Xun: "Good night... drink more hot water."
Lin Ting: "Shut up."
Closing the phone, Lin Xun looked at the date. Recently, he was too busy. He almost forgot what day it is today-indeed it is time.
Lin Ting is studying art abroad and seems to have her own exhibitions. Her studies and career are not easy, and her holidays are rare. But at this time of year, she has to take leave to go back to China.
The two of them grew up with their grandfather, and their feelings were particularly deep. Two days later, it was a grandfather’s day of death. Returning to their hometown to see their grandfather was the rule that they could not beat.
The old man was happy and mourning, and when he was old, he died in his sleep, so there was no sadness, just a little bit of nostalgia. So at this time of the year, he would say something in front of his monument and talk about what he did this year.
He grabbed the ear of the pointer: "Go out with me?"
The pointer licked his finger.
Lin Xun: "Then agree?"
The pointer seemed to understand nothing, curled up like an ordinary kitten, and fell asleep on his chest.
Lin Xun fell asleep.
No dream overnight. The next day, I wrote an algorithm, chatted with Dongjun, and then listened to the sound of the seniors and seniors on the fourth floor going downstairs to remove the devil. The morning passed quickly. When going out to pick up Lin Ting, in order to prevent the pointer from running out to find him again yesterday, after consulting Dong Jun, Lin Xun simply carried the cat bag and brought the pointer to the car.
At 4:20 in the afternoon, he arrived at the airport, found information about Lin Ting's flight, and began to wait at the airport.
Of course, the pointer is also there. He carried the cat bag in front of him and unzipped it.
The pointer protruded his head from the opening of the backpack. There were many people. It seemed to be a little scared. He looked around anxiously, with some airplane ears, and then meowed Lin Xun.
Lin Xun deliberately looked at it, today's pointer has a frame.
He is not a lack of observation-according to observations these days, he found that when there is a frame, the pointer is like a normal kitten, washing his face, licking his paws, and eating cat food. When there is no frame, its behavior is relatively unpredictable, and its tail is more flexible. It can enter and exit at will in the fissures of the Devil Realm, and likes to lie quietly in its arms.
The pointer now has a frame, so, not a liar, but a beautiful kitten.
Lin Xun touched the pointer's head: "Not afraid."
There was a little girl gathered to whisper, and vaguely heard some words like "little brother". When Lin Xun was asked by three girls for a WeChat and asked by four girls to take a photo with him and the cat, Lin Ting's plane finally arrived.
Ten minutes later, he saw Lin Ting.
Lin Ting is a big beautiful woman with long legs and big wavy hair. She has been alone in a foreign country for a long time, and her aura has become stronger.
I saw she was dragging a huge suitcase, wearing a strange and bright thin windbreaker, very shapeless, the windbreaker hem was long at the knee, but the lower body was wearing shorts, showing all the calves and half of the thighs, Lin Xun confirmed It was the style of dressing that he couldn't understand.
He re-zipped the cat bag and carried it on his back, waving at Lin Ting.
Lin Ting walked towards him quickly.
After a scent hit, he was hugged firmly by Lin Ting.
Lin Xun: "..."
With such a warm treatment, he has not received it for several years.
Lin Ting hugged his arms and body as if shaking slightly.
"Sister?" Lin Xun patted his shoulder: "What's wrong?"
After a while, Lin Xun was released by his sister.
He looked at Lin Ting's shoulder and found that her eyes were red.
Lin Xun: "Are you broken up?"
"No." Lin Ting wiped his eyes, his voice a little dumb: "I miss you."
Lin Xun: "Don't worry about it."
"--I miss you so much."
Lin Xun: "Then you will return to your country after graduation, and you will not stay outside."
"Also," his sister seemed to return to normal, and she smiled and began to tease him: "Is there any missing person in Nalin?"
Lin Xun: "No, please can't afford you."
Lin Ting: "I guess you can't afford it. Be good, wait for me to become a rich woman and invest for you."
The next moment, she noticed the cat bag on Lin Xun's back.
There was a cry of surprise from Miss Lin at the airport, and the helpless pointer fell into her arms.
The two recounted their old ways and returned to Chaoyang District in the evening.
Lin Ting booked a hotel in the surrounding area, but today she is going to go to Lin Xun’s wardrobe, and she has to look at the safety and architecture, so she must go to Chaoyang Community first, then have dinner with everyone before finally returning to the hotel.
As soon as the door opened, Wang Jingzhao and Zhao Jianbo shouted "Sister" one by one, and they were very attentive-they had a lot of dealings. When the three of them rented a house outside to be Luoshen, their lives were just a mess, thanks to Lin Ting returned home to look after.
Lin Ting responded happily and talked to them for a long time-she also bought games for each of them.
This time Lin Xun had no acid. He knew what was waiting for him.
Sure enough, Lin Ting took care of Wang Jingan and Zhao Jian, dragged his suitcase to his room, and opened it—
"Sister." Lin Xun sincerely said: "I really don't want to change clothes."
Lin Ting: "You have to try on one by one and tout my aesthetic."
After tossing for more than an hour, when Lin Xun's closet was too full to fill up, Ms. Lin finally closed her hands.
Lin Xun was sitting on the bed, wearing a white sweater that was said to be a luxury brand in autumn, but he could not produce any special features with his aesthetics, and drowsyly hugged the pointer.
"Yeah," Lin Ting took a white bottle from the suitcase compartment and said in an addictive tone, "This year's favorite perfume is just a male fragrance, aquatic, interweaving warm and cold, and it feels suitable for my brother."
Lin Xun perfunctory: "Good smell."
Lin Ting: "?"
Lin Ting: "You smell good without opening my lid?"
She sprayed Lin Xun three times.
Lin Xun wanted to hide at first, but after a second, he was still.
This perfume...
The next second, the pointer's paws scratched in the air: "Meow?"
He opened his eyes wide and looked around the room, as if looking for someone.
This, perfume.
The fragrance didn't smell when it just filled, but as it diffused in the room, the fragrance faded...
It's like the first snow in winter, or the frosty sunlight on snowy mountains.
Isn’t this the one Dongjun used?
Lin Ting looked at his reaction with interest: "How is it?"
Lin Xun had already remembered the smell of this perfume before, and it was equal to Dongjun's breath, and even formed a conditioned reflex. So, he was close to coma at this time, and even felt that Dongjun was not far away.
He felt that his fingertips were slightly soft, and he almost didn't hug the cat, and answered Lin Ting: "It's... quite good."
"That's for you," Lin Ting came to his bedside: "I like to spray it on the pillow, like this..."
With that, she aimed at Lin Xun's pillow and sprayed it accurately three more times.
"Don't." Lin Xun wanted to stop, but it was too late, his sister's hand was too fast.
Lin Ting seemed very satisfied: "This fragrance is still a long time, it will be very atmosphere overnight."
Finished.
Lin Xun wondered if she didn't want to let herself sleep.
