Apart from the city of Yanjing, where Meng Fanqi spent seven years for his master's degree and several months of internship, Shanghai was the city that impressed him the most.
The truth and cruelty of actually wanting to stay but being unable to do so made him still have a strange feeling for this city.
He believes that it is normal to yearn for a big city like Shanghai. What is abnormal is what determines who can stay and who cannot.
Meng Fanqi is now free to make ordinary purchases. This time he came to Shanghai and booked a five-star hotel by the Pujiang River.
I got up early in the morning and walked along the riverside, walking all the way to the south, and slowly strolled around the South District, which has long since been cancelled.
There is a Chenghuang Temple and a garden here. It has always been a must-see attraction for tourists coming to Shanghai. It is located in the most central area.
But in the core area of this national financial center, there are a large number of old buildings in the old city.
A few hundred meters to the east is the Pujiang River, but within a few kilometers south of the Chenghuang Temple, there are almost all dilapidated old cities.
Many of them have to use public toilets and use spittoons.
"Perhaps this is the real Shang Hai." Meng Fanqi walked among them.
Compared with the prosperity and various styles of buildings on both sides of the Pujiang River, Julu Road and Fumin Road near Xintiandi are known as Jufu Road.
Such streets and alleys are actually closer to the real Shanghai life.
Zhang Xuefeng, who had advertised under Meng Fanqi's scarf a few months ago, has now gained some fame in advance by taking advantage of the popularity at that time.
He may be somewhat controversial on many things, but there is one passage that Meng Fanqi has always felt very sympathetic to.
If you want to experience the real Yanjing, don’t go to the Summer Palace or Sanlitun. That’s not the real Yanjing.
Go to the Guomao area and take the 830 bus to Yanjiao; go to Tiantongyuan where millions of people live.
You can ride buses that don’t touch the ground, and you live in a community with a city-level population. It is said to be the largest community in Asia. It has built four police stations and three subway stations.
The same is true for the real Shanghai. Near the crowded Chenghuang Temple are all the old towns, and the quality of life there has nothing to do with the prosperity of Shanghai.
Across the river is Lujiazui, the economic and financial center of Shanghai. The Google Shanghai branch where Meng Fanqi will go in two days is located here.
But even if we are surrounded by prosperity, what do these things have to do with ordinary people?
Meng Fanqi was still very clear-headed about this matter. Shanghai worked part-time and finally settled in Dalian.
Being close to wealth and power makes people mistakenly believe that they have control over them. This mentality is absolutely unacceptable.
Walking in the old streets of Chengxiang, Meng Fanqi did not feel any sympathy for these residents because of their living environment and conditions.
After 2020, Shanghai plans to completely renovate the old city center in the city center. All doors within a few kilometers will be covered with cement and demolished collectively.
Meng Fanqi did not understand the specific policies in detail, after all, he did not have this fate.
I only know that one share is 45 square meters, and the only child is divided into two shares. There are also considerations for future spouses and children, so it is not difficult for many young people in their twenties to get 135-180 square meters.
Many people are still complaining about how they moved from Pujiang to the countryside. Unfortunately, the countryside they refer to is something Meng Fanqi cannot afford.
Therefore, Meng Fanqi felt that he deserved more sympathy than them.
But this is all in the past. A few months after his rebirth, Meng Fanqi has achieved real estate freedom and can live wherever he wants.
After shopping around for a while, Meng Fanqi contacted Wang Kai to go to Baidu.
After chatting for a while, I suddenly realized that this guy was originally from Shanghai.
"Your original home is in Shanghai. Isn't it just a trip home at public expense? Why are you complaining?" Meng Fanqi was speechless after meeting him downstairs at Baidu.
"Brother, no matter how things are, you must give the leader a feeling of hard work!" Wang Kai began to share his fishing rules: "The leader just doesn't want you to be free, and he doesn't want you to be comfortable at work."
"It's true." Meng Fanqi also has a lot of opinions on fishing. Generally, things that are done at three or four o'clock in the afternoon must be delayed until the evening or when the leader asks for a response.
As long as you can get things done, your boss will feel that your work is not full and will give you more work.
When there are many things to do, Meng Fanqi will report work in the early morning before going to bed to make it seem like he has been busy until that time.
"It's okay. If you follow me these days, you won't have to do that." Meng Fanqi sorted out the information and arranged for Wang Kai to understand the background of the algorithm first: "You understand these two pieces of information first, and I'll go over the basic logic. After writing the framework, you can come back to me after reading it."
Hungarian and KM classics are easy to use, and the principles are not that complicated, but people who are not in specific fields will not pay attention to them.
Wang Kai didn't know anything about it before, so he took the information and went to see it.
Meng Fanqi looked around, strolled around, and chose an unremarkable work station.
"It just so happens that no one is currently using this position." Meng Fanqi smiled with complicated emotions. This work station was exactly the one he had used for a long time before he was reborn.
Six or seven years later, various office appliances and decorative items are quite different, and even the scenery outside the window is somewhat different.
Same location, same company, same code.
It's just that the status is completely different.
Meng Fanqi's code transformation work went very smoothly, mainly because he had already considered the expansion of other functions when writing this part of YOLO.
There are still quite a few variants of algorithms based on detection. Meng Fanqi, who is best at visual algorithms, has long left interfaces for easy modification in the corresponding locations.
At first, it was just because of limited resources that we couldn't run so many experiments, so we only did the most basic part.
I thought it was to facilitate my fellow programmers to do secondary development, but I didn't expect that I would be the first to do secondary development.
Meng Fanqi, who had a clear idea and was familiar with the road, quickly extracted some features from several key positions of the YOLO algorithm diagram.
Based on the information of the marquee, I designed the display method of each marquee in a single frame, and added the Hungarian algorithm to test the matching situation.
Meng Fanqi was very familiar with this series of tasks, so it only took him more than an hour to complete half of it.
The weighted Hungarian algorithm is actually the KM algorithm. In this project, Meng Fanqi specially designed the matching weight calculation method for the government scenario.
It can be said that for such a single scene, the effect is completely good enough without using the Kalman filter.
However, because the development was so smooth, Meng Fanqi was not going to be lazy. He planned to take a lunch break and add the Kalman filter in the afternoon, and the matter was considered completed.
"The hell is it almost finished?" Wang Kai spent the whole morning looking at it. He had just barely understood the principles and processes of the two algorithms, but Meng Fanqi told him that the matter could be finished in the afternoon.
