God of Money

He focused on debugging as he ate dinner with a burger. Park Joon-woo and Kim Yong-gun heard his footsteps, and Yoon Gi-hwan couldn't go around him like a poop puppy. At that moment, the dominant star was obsessed with another thought.

'We have $55,000 now, and if the consulting project is signed, another five. That makes 150 million. Not bad.'

The reason dominance was so relaxed was because the fixes for the problem were not so big. The current server-side problem that is occurring is simple to know, and if you do not know, it is always unknown. The solution was already neatly organized in the memory of the dominant.

'Let's repay the student loans first, then give the parents 2,000. Some of the other 5,000 can be mined and deposited as reserves for cryptocurrency transactions. If we had the chance, we'd invest in stocks in the financial crisis.'

I planned out what to do with each money. I was thinking about something else, so I was slow to tap my keyboard naturally. Shiny circles around his ears quietly shouted.

"Hey, you know how many people are watching this right now? Do it right, huh?"

There wasn't just anyone in the system around here. From the people in the ST data system who were in charge of the account to the people in the ocean system, the primary partner. The dominant opened his mouth.

"Are you in charge of server side? I think we should take a look at the part where we place a sale order and update the customer's balance with an amount excluding securities company fees."

A man dressed in a clean shirt was approached by a dominant horse.

"Server developers are currently debugging. I am Kwon Hyun-kyun, the server side PM."

PM.

At the end of the project manager, he is responsible for scheduling development, managing people, and coordinating with the field.

"Ah · · · · Ticket PM."

A year later, he offered to move to the ST Data System to see if he had a good view of himself working here when the loan system pulled out of Noorie. I chose a job because it was better in size and salary than in large scale, and I spent over six years there. Memories of the past came back to me.

"Is there a problem with that?"

"The sale order will be executed and the remainder will be updated in your balance, excluding securities company fees. Is that correct?"

Kwon Hyun-kun nodded.

"There are two types of securities company fees at this point."

Kwon Hyun-kun nodded again. As he approached the problem, he was overwhelmed with a choking tension.

"Customers who pay ₩ 15,000 a month charge 0.00811%. It's kind of a convenience for a lot of customers. We're charging 0.01 percent to regular customers."

He continued to speak calmly and logically.

"So here's the scenario. Place a Sell Order. Transactions are concluded, demand is based on customer information. Update commission limit to balance. Is that correct?"

He did not listen to the answer, pointing to the visual studio program that was floating on the monitor.

"Here's the server side code for the implementation. The 452 line in the StockTrade.cpp file is the beginning. There is also an implementation where you get the commission rate of the customer on line 512. So let me randomly call this function."

result value: 0.011.

The screen continued to display only the same values. He shouted without speaking, and without restraint, he shouted.

"Hey! Ahh."

I took a moment to look around and slowly said.

"Tell me more, tell me more."

"Commission rate. It's being charged the same way."

Kwon Hyun-kyun protested immediately.

"No way · · · I definitely checked the DB value · · · · · · ·."

Kim Jong-wook looked at Kwon Hyun-kyun and said,

"Are you sure it's in there?"

Kwon Hyun-kun tilted his head and replied.

"I've checked for sure · · · Let's check again."

Then I picked up my phone. Shinhwan swallowed a dry saliva looking at his dominant figure. I think I picked the wrong one. While waiting for the phone call, Yooseong smiled and said.

"You don't have to call. because I'm not writing that value in the code anyway."

"What · · · · · ·?"

"If you look here, I'm writing the value declared in const format. They're getting the commission rate wrong."

the const type was a type of method that defines values used as constants (defined values). After all, it means that the code is hardcoded rather than fetching and using the correct values from the database.

Instead of simply changing the DB value every time demand changes, we had to go through the process of modifying the code, downgrading the server, and restarting it.

Kwon Hyun-kyun, who was on the phone, pushed out his head and saw where he was pointing. Other developers around me lifted their heels and checked.

const double GENERAL_FEE 0.011;

const double SPECIAL_FEE 0.011:

The dominant was right. Kwon Hyun-kyun muttered quietly.

"Why is this so · · · · · · · · · · · ·."

I opened my eyes how many times I couldn't believe it. However, the code did not lie. This time, the voice of Kwak Jin-wook increased.

"Don't do that, go check the code with the server developer right now and start testing!"

“I'm not a friend to make these basic mistakes. ”

Kwon Hyun-kyun still did not believe. However, the code downloaded from the SVN was sure that they had uploaded it. There was no excuse. Yooseong told Kwon Hyun-kun.

“You may have missed the test, or you may not have succeeded in the freelance developer's work. If you modify the server side and the deployment procedure we discussed earlier, this problem will be shorted out. ”

Kwon Hyun-kyun left with a blank expression. Yooseong looked at Kwak Jin-wook and said.

“If you switch to the development process we spoke about verbally, this case will go away. So the sooner you apply it, the better. The more time passes, the more complex the code gets, the more operational it's going to cost. ”

Slowly, developers were scattered from thinking the situation was over. After work, the dominant star checked his watch.

Ten o'clock at night.

Check the actual code and it will be 12 o'clock by the end of the test.

He said, looking at Yoon Ki-hwan.

"I think I'll be home by 12: 00, 5,500. You haven't forgotten?"

"You · · · You · · · · · · · · · · · ·."

"Go ahead."

"What the hell are you?"

"Haha, you seem to be hearing that a lot these days. I'm a new developer at the big leagues. Beyond that, be prepared for further consultations. I've demonstrated my ability, but nothing has been decided yet. Don't forget my 50 million won is in your hands. “

Shinhwan opened his eyes and said nothing.
