All day, Li Lin was struggling with the computer, staying in the office and writing software. However, now the output speed of Li Lin's software has slowed down, not because his writing speed has slowed down, but because he has begun to write small and medium-sized software.

A small or medium-sized piece of software takes about a programmer to write day and night for a week to complete, which means 7 times 24 hours. If you count it as a person working 8 hours a day, it will take about 20 days to complete. Of course, there is no official standard for dividing the size of software, in other words, there is no quantifiable way to distinguish whether a software is small, small, medium-sized, large, etc.

If it takes 7 times 24 hours to develop a small and medium-sized software, then for Li Lin, basically two such software can be produced in a day, that is, it takes about 3 hours to make one.

And the software that Li Lin wrote today was planned by him a long time ago. This is a specially prepared for people who work outside, commonly known as ticket-grabbing software, there are almost no particularly professional ticket-grabbing software on the market, which is the purpose of Li Lin to write this software. As the name suggests, the ticket grabbing software is used to automatically buy train tickets, and the core of this software is to simulate the request of the client, so that the action of buying tickets is automatically completed by the program, which is the so-called automatic ticket purchase.

This method is somewhat similar to the way hackers brute-force passwords. Brute-force cracking of passwords, in layman's terms, is to write a program that automatically tries all kinds of passwords until it succeeds. And this process is often the process of simulating login with a program, which is very similar to the way of simulating buying tickets in the ticket-grabbing software.

For example, if you have a website with a password of 6 to 30 digits, then when the hacker knows your account, they can try all combinations from 6 digits all the way to 30 digits until you have a successful login, at which point the password will be cracked.

But the road is one foot high, and the magic is one foot high. There are many ways to deal with brute force attacks, and the most common ones are generally two. The first is to let the user fill in the verification code, because the verification code is transmitted in the form of a picture, so it is difficult for the program to automatically scan the picture and analyze the numbers in the picture, which naturally prevents brute force cracking. The second is to limit the number of password errors in the account, that is, when the password of an account is entered incorrectly more than 3 or 5 times, or any specific number of times, the account will be locked for a period of time, which can also effectively prevent brute-force attacks.

Of course, the second way actually has certain loopholes, if there are malicious people, using someone else's account, deliberately entering the wrong password, then it will cause someone else's account to be locked for no reason.

Of course, this is a bit far away, back to the topic, this ticket-grabbing software written by Li Lin has great advantages compared to the ticket-grabbing software currently available on the market. At present, the ticket-grabbing software on the market, more precisely, should be called ticket-checking software, ticket-checking is an offline operation, in layman's terms, that is, you can check tickets without logging in to your account.

This kind of ticket checking operation will be relatively simple to simulate. And this one made by Li Lin is a real ticket-grabbing software. This software can not only automatically check tickets, prompt users when there are extra tickets, but also simulate user logins and even simulate the operation of buying tickets.

This is very tempting, users only need to enter their account password, and then specify the information of the ticket to be bought, and they can sit back and wait for the train ticket to be delivered to their door. Of course, in this process, the user also needs to enter the verification code twice, once when logging in, and once when buying a ticket, this process cannot be completed by the program, because it is difficult for the program to scan the numbers in the picture and automatically fill in the verification code.

But even so, Li Lin's ticket-grabbing software has been far behind other ticket-grabbing software on the market. However, this is not to say that it is difficult to simulate login and buy tickets, because in essence, this is the same method as simulating the query of remaining tickets, which can be called simulating a network request to put it professionally. To simulate the actions of logging in and buying tickets, it is necessary to analyze several network requests and then use the program to simulate them.

Li Lin's software is expensive to strike first. It is foreseeable that software that simulates login and ticket buying operations will appear on the market sooner or later, and Li Lin is just one step ahead. Of course, a piece of software doesn't decide anything, but if it adds up, it will allow Gao Chao to better occupy the free software market in the future.

After getting off work, all the superb employees, plus Li Lin, a total of 12 people, came to a cafeteria. This place was suggested by Li Shan, the company's HR specialist, and the per capita consumption is 50, but the food and all kinds of drinks are available, but it is also affordable, and the food is quite good.

Among Gao Chao's current 12 employees, including Li Lin, He Kun and Qin Tian, developers alone account for two-thirds, and there are 8 programmers. The remaining four people are a product manager, a tester, an HR specialist, and an accountant. Strangely, all 8 programmers are men, while the rest of the positions are all women.

This is also why, in many IT companies, the programmer brother and the girl in other positions are put together. There's only one reason for that, because almost all programmers are men.

12 people gathered around a table, Li Lin sat on the main seat, and took the lead in raising a glass and standing up, "Come!" Let's replace wine with drinks and toast to the superb together! ”

"Cheers to the superb!"

"Cheers to the Big Boss!"

"Cheers to the heroes!"

"Cheers to tomorrow!"

Everyone shouted their own unique slogans, and drank the first glass of wine in the superb team building activity in the collision of wine glasses.

Everyone is young, so it is natural that communication is completely barrier-free. The oldest among Gao Chao is Ji Xiyan, but although Ji Xiyan is very serious when she goes to work, her style of doing things is relatively clean and neat, and she is a royal sister with a hot personality, but in the final analysis, she has not married and had children after all. Therefore, there is still a hint of girlish feelings in Xiyan's character, and when she is with Li Lin's group of young people in their 20s, she will not feel that there is a generation gap.

Because I knew that we were going to have a team building dinner at night, and we were eating a buffet, so we didn't eat much at noon, and there were even two programmers who were more hanging, in order to fully implement the strategy of holding on to the wall to go in and then holding on to the wall to come out, they didn't eat at all, but to the extent that the two of them were hungry, they were not hungry and went in with the wall.

However, when everyone came out, there was really someone who came out with a wall, and this person was what everyone said in private to tease the boss He Kun.

"Second boss, you're too ashamed. You didn't look at the expression of the barbecue chef just now, it was like a mouse seeing a cat, and you were almost trembling with fright. As an HR, Li Shan is familiar with most people in the company, so she doesn't have any scruples when she speaks.

"Don't blame me. I am an affirmation of the skill of the barbecue master, who made him make it so delicious. He Kun pouted and said.

Hearing He Kun's shameless words, the big guy suddenly couldn't help laughing. After a burst of laughter, the test girl in the company fell on Li Lin and asked expectantly, "Big boss, do we have any other activities?" ”

Hearing the test girl's inquiry, everyone's eyes were focused on Li Lin, except for Ji Xiyan's eyes were quite calm, the others obviously didn't enjoy it yet. It's no wonder that eating is usually just a prelude, and it's only a little over 8 o'clock now, and tomorrow is Saturday and you don't have to go to work, so it's no wonder that this group of young people can enjoy it.

"Who has good advice?" Li Lin really thought that everyone would have a meal together at first, so he just asked Li Shan to help find a place to eat.

"Do you want to go to karaoke?" The person who spoke was also a junior programmer in Gao Chaoli, and in the group of programmers, he was considered to have a more lively personality.

"Karaoke is too cheesy, how about going to a bar? There are many people and there is more atmosphere. ”

Hearing Li Shan's proposal, everyone couldn't help but feel a little moved. Most people have been to KTV, but the bar, it can be said that at least more than half of those present have not been there, and the place that has not been to is obviously more arousing the curiosity of everyone.

"Vote by show of hands." Li Lin proposed: "Raise your hand if you choose to go to KTV." ”

Seeing that everyone looked at each other, and no one raised their hands, Li Lin waved his hand and said, "Go to the bar!" ”
