"I'm sorry, I misunderstood, I'm really sorry to disturb your rest."

Ye Tang hung up the phone, with mixed feelings in her heart, in her previous life, she ran to the other side of the ocean, away from Luo Xingchuan, and drew a line with him. Now that they really don't have anything to do with each other anymore, she has a feeling that something has failed.

But that's okay, in this life, she is only a passerby in Luo Xingchuan's life, and after the college entrance examination, they will not cross paths again.

……

The next day, Ye Tang handed over his number plate to Tian Wen in person.

"Teacher Tian, you go to receive the award for me, I'm just a student, I have to sprint for the college entrance examination next, not to mention traveling around the world, I can't go anywhere in China, it's a waste for me to take a koi card, you have winter and summer vacations, and you can take your family out to travel when the time comes."

Tian Wen didn't take it, hoping that he would win the lottery and coveting his student's prize were two different things, "Yes... It's yours... It's yours, you... Your luck sends... Give it to someone else, and you won't... It doesn't work, I... I'm still waiting for you... You take the college entrance examination to create... Miracles are done. That... That's when I... I can get the bonus, no... Not more than one... A card is more... More attractive? ”

Ye Tang finally failed to send out this koi card.

Everything went smoothly to the New Year, with a three-day holiday on New Year's Day, and a half-day holiday on the third day, January 3, the school. Except for the winter vacation, there is less than five months left for everyone to review, and Mr. Tian said, "When you are admitted to your ideal university, you can play as much as you want." ”

The New Year is celebrated at the beginning of February, and there is a January adjustment exam at the end of January.

Cen Yannan and Chen Yumo, who had never taken learning seriously before, felt that there was not enough time.

Especially Cen Yannan, his current learning state is almost to the point of forgetting to sleep and eat, and the dream words he says at night are all reciting performance-related concepts.

January 4 was the date of the film school re-examination, and he was very stressed. No. 3 can rest for half a day, he did not leave the school, continue to stay in the classroom for self-study, holidays are the best time for mahjong room business, the noisy environment makes him unable to study quietly.

After noon, only Cen Yannan and a few students were left in the classroom.

Mingxue had just left.

Chen Yumo lived in school and had nowhere to go, so she planned to stay in school and read, but her sister called her and asked her to go home, saying that her mother hadn't seen her for a long time and missed her.

As for Luo Xingchuan and Ran Tianyi, as soon as the school bell rang in the morning, they left in a hurry, as if they were in a hurry.

Ye Tang can't accompany Cen Yannan to study, the books she has studied recently are not high school textbooks, in case they are seen by other classmates and teachers, it is difficult to explain. And in addition to reading, she needs the help of other objects.

Computer science is a rapidly evolving technology, and if you stagnate a little, you will fall behind a lot, and you have to work twice as hard to catch up with the latest things, which is why many programmers are forced to retire at the age of 35 - very few people can continue to study at high intensity all their lives.

Ye Tang's computer level is still stuck seven years ago, she has not lost the knowledge she has learned, but there is no progress, and her knowledge is outdated now. And the reason why she was able to hack into the inside of Yuchu Department Store and the cameras along the street is also because the monitoring system has not made any progress in recent years, and if it is a tighter system, she can't easily invade.

Professor Dong has retired, and cryptographic security technology is no longer the mainstream of this era.

From the moment he decided to return to the Department of Computer Science of A University, Ye Tang also decided on his future research direction - artificial intelligence. Seven years ago, artificial intelligence was still an emerging thing, and it was also an area that Ye Tang was very interested in. She started from the basics and didn't expect to build a robot all at once – that's her goal for the future.

A few days ago, Sister-in-law Liu took advantage of the Shuangdan event to buy a sweeping robot with free shipping for 199 yuan on Taobao, and felt that she had been deceived when she bought it.

Liu's sister-in-law complained to a few neighbors, "My house is big, I wanted to clean it more easily, but the cleaning ability of this thing is not as good as my broom, the rumbling noise, like the start of the train, I just swooped around, the dirtier the ground is, and it also broke my coffee table and TV cabinet!" I want to return it, and the customer service says I won't use it! What else do you say that used electronic products can't be returned for seven days without reason! I'm, 199 yuan to buy a lesson! ”

She threw the robot vacuum directly next to the trash can.

It happened that Ye Tang got out of school early that day - she took leave in the afternoon and went to the Red Leaf Lijing Hotel to redeem a koi card. The rules of the event say that the prize must be redeemed on a working day, and it must be between 2 pm and 5 pm.

More than ten years have passed, and the attention of the red leaf koi activity is not as high as the first few years, and the media is no longer guarding the door of the hotel to photograph who is the luckiest koi.

When Ye Tang claimed the prize, the general manager of the hotel did not appear. After the staff confirmed that the number was correct, they asked her to hold the koi card and take a photo with a smile, saying that the photo would be posted on the official Weibo and WeChat public accounts later. Ye Tang did not object. She is a person who has done live broadcasts and is not afraid to show up on the Internet.

When she came back with the koi card, she saw Sister-in-law Liu throwing out a large object in a huff.

She picked it up and saw that the machine was still brand new.

Sister-in-law Liu complained to Ye Tang again, she doesn't like to hold back when she encounters bad things, and she can't wait for everyone to know that she can feel better in her heart.

Ye Tang kept nodding his head to show sympathy, "You really don't want it?" ”

Sister-in-law Liu waved her hand in disgust, "Don't want it, don't want it, you can take it if you want it, but I'm ugly in front of me, this thing is not enough to be successful, and when the time comes, I won't be responsible for breaking your furniture." ”

Ye Tang smiled, "It doesn't matter, I don't have any valuable furniture at home." ”

Sister-in-law Liu was speechless, "That's the same, okay, you can treat it as a toy." ”

The sweeping robot is quite heavy, estimated to be ten pounds, and the volume is not small, Ye Tang took it home.

She recently happened to be learning the SLAM algorithm for the vision part of the robot, and there was a lack of an experiment for her to practice. Liu's sister-in-law said that the sweeping robot always hits furniture, which means that the SLAM algorithm in its built-in program is not sophisticated enough, or it does not use this algorithm at all, so it cannot perceive obstacles in front of it.

Ye Tang is ready to rewrite the program and implant it in the sweeping robot to see how it works.

Finally, there is a half-day holiday on New Year's Day, and she should be able to finish it.

After eating at noon, she locked herself in her room and began to tinker, she had almost written the program, and the rest was practice.

Zhao Zhenfang didn't know what she was doing, and she didn't know what the use of the large garbage she picked up, and thought she was reading a book and doing a question, so she didn't bother her.
