Chapter 242: We are professionals in passing the buck
After the four of them returned, they discussed together the solution to this problem.
This time, Xu You and Lou Song were still the core members, responsible for converting this problem into a mathematical model to solve it.
Although Luo Wenkun and Lin Shi are far from the level of Xu You and Lou Song, after learning, they have a certain understanding of the problems of this model and play a supporting role.
After the joint efforts of the four people, they used three days of their spare time to complete the transformation of the mathematical model and finally found the pattern of the bug.
Due to some special structures of this brand's processors, some division calculation results in the converted mathematical model may have slight errors compared to the true values.
It is this error that causes the software to freeze.
This can be fixed by modifying the code.
This error can be corrected by selecting the problematic division equations and multiplying them by a constant before performing the division.
After successfully solving the problem, the four of them were very excited.
"I didn't expect such a difficult problem to be solved so easily!"
If Luo Wenkun had not been personally involved in it, he would never have thought that the solution to this problem would be so simple.
However, for some problems, the difficulty lies in locating the bug.
If you fail to locate the bug accurately and start from the wrong direction, the problem will only become more complicated.
Just finding the real cause of the problem is equivalent to solving 99% of the problem .
"Lou Song's mathematical modeling is indeed very crucial. If Lou Song hadn't mentioned it, I would never have thought that the whole problem could be converted into a mathematical model to solve it." Xu You said.
Through this process, Xu You also realized that his computer skills were still very lacking .
In other words, Xu You is not able to connect mathematics and computers very well.
In this regard, Lou Song is indeed more capable.
After that, Xu Youke had to drag his suitcase to the library to look for some books.
"You should define the problem first, then I can think of the mathematical modeling method." Lou Song said.
Lou Song remembered very clearly that it was Xu Youxian who discovered the common structural features of the mobile phone chips that caused the bugs.
Each of them believed that the other was the key to solving the problem.
"Okay, okay, you are all awesome, and we two are just there to make up the numbers." Lin Shi said helplessly.
It is obvious that Lin Shi has already achieved the best in the Physics Department of Jilin University.
But when compared with the two monsters Xu You and Lou Song, Lin Shi seems to be dim.
Even so, Lin Shi hopes to suffer more such setbacks so that she can recognize her own shortcomings.
Being with them, Lin Shi will learn a lot in a short period of time.
Afterwards, Luo Wenkun took the three people back to his company and explained to the employees that they had solved the bug.
"Mr. Wang, the bug has been fixed. Please take a look at the modified code. The modified parts have been marked. If there are no problems with this version, we can prepare to release the internal test version."
Wang Zhi was shocked when he heard Luo Wenkun's words.
Did they actually locate and fix the bug?
But it’s only been a few days?
You know, it was this bug that more than a dozen people in the company's programming department failed to completely solve in two whole weeks.
Although the company's team is still relatively young, they are very capable and are not inferior to the teams of some large companies in terms of level.
It is just that due to the relatively small number of people, it is normal that some tricky bugs cannot be solved in a short period of time.
In order to confirm whether the bug was really fixed, Wang Zhi decided to let a few employees test it first.
"Then Mr. Luo, I'll let them run it on their phones first to see what the experience is like now."
"Well, you guys should test it first."
In fact, before this, Xu You and his team had already tested it with those models of mobile phones and confirmed that there were no problems.
Luo Wenkun knew that Wang Zhi might have some doubts in his heart, so he asked them to take a test to prevent them from not believing it.
Next, Wang Zhi called a few people in the team to retest this version of the app.
After preliminary testing, the previous bug no longer exists.
Apart from this, there have been no new bugs such as abnormal power consumption.
After getting this result, Wang Zhi felt a little complicated.
Solving a bug should be a happy thing.
Unfortunately, this was not something their team was able to resolve.
Instead, it was solved by several classmates of their boss.
This situation did make Wang Zhi feel a little embarrassed.
Wang Zhi was poached from a large factory by Luo Wenkun at a huge price.
The salary Luo Wenkun gave Wang Zhi was 50% higher than Wang Zhi’s previous salary.
As a result, this situation occurred not long after I arrived.
This indeed made Wang Zhi feel a little complicated.
After returning, Wang Zhi said to Luo Wenkun:
"Mr. Luo, after preliminary testing, the new version of the app does not have these bugs. What is the principle behind this? Can you tell us about it?"
Wang Zhi just looked at the modified code and unexpectedly found that the modified parts were very small.
As for why this modification was made, Wang Zhi didn't quite understand.
"Xu You, tell everyone about it."
Next, Xu You explained to everyone the specific cause of this bug and how to solve it.
Xu You is much more experienced in explaining problems than Lou Song. He does not make sudden jumps in his explanations, but instead simplifies some complex issues.
After Xu You’s explanation, everyone finally understood the reason for this bug.
"I was wondering why similar bugs sometimes occurred when other companies were developing mobile phone software. It turns out that this is a common problem with the chip of this model of mobile phone." Wang Zhi sighed.
"So, other companies haven't solved this problem either?"
"Well, I haven't encountered this solution before. When there is occasional lag, we will blame it on the corresponding model. It is their optimization problem." Wang Zhi said with a smile.
For example, those very popular apps do not take into account the optimization issues of each model.
It's completely different from their new company, which takes every detail into consideration.
"That being said, we can apply for a patent for this technology," Luo Wenkun joked.
At this time, Wang Zhi remembered what he was worried about just now, and said quickly:
"Mr. Luo, this matter is still my fault. I couldn't solve it within the normal time limit, and I have to ask your friends for help. I promise that this situation will not happen again in the future."
