Rebirth Starts at 7 Million

People like to think wildly when they are free. Luo Fan, who is lying on the hospital bed at the moment, has nothing in his hands, and can only pass the time by thinking wildly.

As a rebirth, Luo Fan naturally thought about how to seize the opportunity of this rebirth, not to mention earning his dozen or twenty small goals.

Luo Fan was a code farmer in his previous life. He was best at typing codes, and what he remembered most in his mind was code.

What stocks, gold, bonds he did not remember all the direction, the only impression is the fund.

In December 2020, Luo Fan saw that his colleague bought liquor and medical funds and made thousands of dollars every day. He was also moved and fell into the pit. As a result, the fund began to plummet within a few days, while his colleague had already secretly run away.

Later, at a dinner party, Luo Fan's colleague told him that when a person who has never played with funds is in the pit, he has to run away quickly, or wait for the leeks to be cut!

In addition to these financial products, Luo Fan also remembers that Germany won the World Cup 1-0 with Argentina in 2014, and the French team defeated Croatia 4-2 to win the championship in 2018.

Then there is the legendary Bitcoin that must be bought for rebirth.

and many more! Year 2009! It's 2009 now! Luo Fan's eyes suddenly lit up and he remembered a very important thing. In the early morning of June 9, 2009, Apple released the iPhone 3.

The Android system was released on September 23, 2008.

This shows that the era of smartphones has actually begun.

Thinking of this, a lot of ideas popped up in Luo Fan's mind, the two clearest of which were facial recognition and listening to songs.

(ps: The concept of facial recognition roughly appeared in the 1960s, and its initial shape was in the 1990s, that is, the traditional face recognition technology based on visible light images.

What the protagonist is talking about here is the multi-light source face recognition technology based on active near-infrared images, which is later used in commercial applications, especially face recognition on mobile apps, and its related patent registrations are after 2010, and most of them are. Registered by Ali. )

Some people may not be very clear about facial recognition, but when it comes to smiling face recognition, most people should have an impression.

Smile recognition is an application of facial recognition. As the name suggests, smile recognition is a technology that recognizes people's smiling faces through AI. This technology is mostly used in photography.

When taking a photo, the camera will intelligently recognize the face in the picture, and perform special auto-focus on the recognized face, which can make the facial expression of the person in the photo more real and clearer. Smile recognition is that the camera will automatically Recognize the smiling expressions of people's faces, and take special auto-focus photos on people's face areas.

Smile recognition was originally carried on the Sony T200 camera, which was released in 2007, which means that the smile recognition technology has actually appeared.

But Luo Fan's facial recognition here is different from Sony's smile recognition.

This facial recognition technology combines big data and a new set of AI algorithms. More importantly, the application of facial recognition is not only in taking pictures.

The facial unlocking of mobile phones in later generations and the face-swiping payment of Alipay all use facial recognition technology.

There are too many apps for facial recognition. Luo Fan has typed the relevant codes many times in his previous life. These things have been engraved in his mind. If Luo Fan is willing, he can come up with facial recognition technology now.

Of course, limited by the current AI algorithm and camera accuracy, facial recognition is difficult to achieve the level of the previous life.

In addition to listening to music.

This technology is also quite familiar to Luo Fan. Luo Fan joined a music app company when he started working in 2013.

At that time, the app required them to go all out to overcome this problem because Penguin Music was equipped with the technology of listening to and recognizing songs.

Listening to a song to recognize a song, to put it bluntly, is to use the audio fingerprint algorithm to extract the fingerprint of each song, and establish a song fingerprint database. When the user requests a recording, the audio fingerprint of the music will be extracted first. The fingerprints are then compared and matched to find the song with the highest matching degree in the database.

It's easy to say, but very difficult to do. At that time, Luo Fan's technical department worked day and night for two months to completely conquer this technology.

Since then, the relevant code of this technology has been engraved in Luo Fan's mind.

Luo Fan made up his mind that as soon as he was discharged from the hospital, he would type out the codes for facial recognition and music recognition, and then go to register the patent.

With these two technical patents, the annual licensing fee should be enough for him to achieve economic freedom.

Thinking of this, Luo Fan suddenly felt an unreal feeling. He subconsciously pinched his arm. With the sharp pain, Luo Fan confirmed that he was no longer dreaming, and he really returned to June 9, 2009.

Unconsciously, three days passed. Just like in the previous life, after three days of drips, the tumor on the back of Luo Fan's head completely disappeared.

For the past three days, Luo Fan was suffocating in bed. Fortunately, Zhang Shuai came to see him yesterday and stayed with him all afternoon.

Hearing Zhang Shuai ramble about things at school, some things in Luo Fan's deep memory were also dug up.

Luo Fan's high school is the No. 1 middle school in their city. The students of No. 1 middle school are divided into three types. The first type is the one who takes the entrance examination every year. This kind of high school is the top 300 in the city's high school entrance examination, and the score for the 300th is A fractional line.

The second type is 300 students and later, almost 200 students are accepted every year, but these students have to pay if they want to enter the first high school. No amount of money.

The third type is art students, only those who have studied an art since childhood and scored at least 500 in the senior high school entrance examination. The number of such students is usually 7.80 at least.

The competition pressure of No. 1 Middle School is very high. In ordinary high schools, only the second year of senior high school can be divided into arts and sciences.

Then the classes will be rearranged every semester. The top 50 in the final exam are in the top class, the 51 to 100 are in the emphasis class, and the rest are ordinary classes.

The top class is the best student in each grade of No. 1 Middle School. The worst students in it have to be admitted to 211. The goal of the emphasis class is to be admitted to one of the worst, and the ordinary class is two.

It is worth mentioning that the high school in the county-level city of No. 1 Middle School has an undergraduate rate of 97%, which is stronger than that of some provincial key points, but the primary school rate is much worse.

After all, what the province focuses on is the top students in a province, and the grades of any class that they pull out can be roughly equal to that of the focused class in No. 1 Middle School.

Luo Fan and Zhang Shuai have not always been classmates. Luo Fan's grades have always been at the forefront of the school's science subjects. In fact, it should be said that the top three are more suitable. In the past three years, Luo Fan has fallen out of the top three once.

On the other hand, Zhang Shuai's grades have always been ups and downs, jumping left and right between the top class and the emphasis class.

However, Zhang Shuai was in the top class in the second half of senior year. He was "popular" in the final exam in the first half of senior year. He scored more than 590 points, just 50th in the school.

In the top class, Zhang Shuai was always the last in the class. Every time Luo Fan and Zhang Shuai met, Zhang Shuai would always complain about this, saying that he would not be admitted to the top class if he knew it earlier. three's.
