Why is it line 83?

In early April, in a "Little Black Room" conference room in Ali, five programmers with the ultimate pursuit of code participated in the final competition for the "Duolong Award", the highest honor in Ali's code field. As the first-generation programmer of Taobao, Duolong is also a god in the hearts of many technicians.


Duolong's focused eyes when reviewing the 83rd line of code is simply cool and handsome~

At the code review site that day, seeing the end of a code snippet, Duolong suddenly added a sentence and scrolled up to line 83. The code is usually a few hundred lines. When he saw it, he still remembered a slight flaw in line 83. This must be how he was in awe of the code.

"Technically blind" Peng Lei and Ma Yun also came to "post code"

Alibaba's technical partners have played to a new height of code sharing, some posted the first line of code and the latest code, some posted JVM code written in high school, and some recalled that this code once It was quickly reviewed by which great god. Some of the business codes that are running at the moment were written by a certain program Yuan in a certain year, and they are still stable and smooth at the moment. Some shared that a certain section contributed 325,000/second and The code for these two magic numbers of 256,000/sec.
In addition to the postcodes of the tech giants, Peng Lei, who was born as a liberal arts student and mocked herself as being "technically blind", also recalled that she wrote two lines of perl under the guidance of Zhou Yuehong in 1999, which attracted bursts of onlookers; even Ma Yun's father also Proud and ashamed to say: Jack Ma is a complete idiot when it comes to code. I am proud that we have so many talented engineers and programmers (source) in Ali. We work together to write the code for economic development, and we strive to write the future. Every line of code for the world's economic and social development. "
This code show, story show, and great talent show on Ali's intranet set off a cultural tide of code from statute to code sharing.

They actually posted the code like this, everyone come and comment
1. @StoryOld Immortal - I have been playing since I started contacting the website until the 83rd line of the current website code. It is an ordinary line of code, there is no special place, but I can't help but remind myself of the original love and expectation, That was a little surprise and excitement when I first came into contact with code.

2. @黄一刀 - My 83 lines of code are comments

4. @海的云 - I feel that it should be the 83rd paragraph. Since I used Jupyter Notebook, all "code lines" have become "code segments", /(ㄒoㄒ)/~~

5. @floating recursion - what? Actually exposed their own CSS naming is not standardized! No, I have to post another paragraph to prove it, sometimes it's standard ~ for example, the code near line 483!

6. @gfriend_24-initial code snippet (BMI calculation program code when getting started with Android development)
