Chapter 240 Still Need to Learn More (Part 2)
Chen Ran got up furiously, lowered his head and said seriously, "President Xiao Mu, I'm sorry, I'll tell them to change it."

Fifteen minutes ago, when she heard Su Xiaomu begin to tap the keyboard rhythmically, she knew something was wrong.

"Forget it, I've finished changing it."

Su Xiaomu sighed softly, feeling a little worried, "Xiao Chen, tell me honestly, what is the standard of your colleagues in the R&D department?"

"Of the rewritten codes you gave me, they are scattered. I can see that dozens of people are responsible for them, and only three of them have no minor bugs."

To be honest, if there is no supercomputing, Su Xiaomu will not be able to find so many small bugs, or to put it lightly, he will not be able to find these small flaws if only Su Xiaomu uses an ordinary computer to simulate and debug calculations.

I admired in my heart, the supercomputer is really convenient, looked at Chen Ran and said, "It's the branch 32 of Python, this part is very standard, it feels like your style, although I haven't seen your programming."

"The other two are more flexible, one is in C, the other is in Java..."

Chen Ran thought for a while, and replied in a straight-forward manner, "I did write the Python one. My comprehension is not very good. The C one should be research and development..."

If it were someone else, they would generally not be able to tell who was who, but Chen Ran could, because she wanted to be the best.

Su Xiaomu hummed, and said calmly, "Forget about this time, you can tell the colleagues in the R&D department that programming is a matter that needs to be serious and careful, don't really completely liberate your nature.

The company's official products are now maintained by the product development department. If it is still at this half-baked level, I think colleagues in the R&D department should reflect on it. "

Although there are indeed jokes on the Internet that the nature of programmers is to create BUGs, create more BUGs, and then solve BUGs and create new BUGs, but this cannot really be done.

Chen Ran nodded quickly, "I understand, Mr. Xiaomu, I will tell my colleagues seriously."

After Chen Ran left, Su Xiaomu put down his work and went to Su Ho's office.

In terms of programming, he is a serious and a bit strict person. Now that there is such a problem in the R&D department of Mushu, it is impossible to just beep and forget.

"Why are you here? Shouldn't you be very busy today?" Su Ho stared blankly at Su Xiaomu who walked in, and then said, "Why are you so stern? What happened?"

Su Xiaomu sighed and said, "I originally thought that programmers with work experience would be much better than those who came out of school, but I didn't expect to be disappointed this time."

"...That's the thing, I also want to say that they work efficiently...

Although so many small bugs were discovered with the help of the ultra-high computing resources of the supercomputer, there may not be so many in ordinary personal computers, but this is not a reason..."

"I want to forget about this matter first, but we have to know what to do and solve this matter." Su Xiaomu said seriously.

At least the current Mu Shu Company is still a technology company whose core is R&D, and it is these programmers who made mistakes today.

Su Ho also became serious, "This is a big problem. When recruiting R&D engineers, Mushu Company uses talents in an eclectic manner and does not include academic qualifications in the necessary assessment scope.

The remuneration offered is also slightly higher than the same level of peers, but now it seems that most of the colleagues in the R&D department cannot afford to be the leader for the time being. "

Su Xiaomu shook his head, "No, it's not that I can't afford it, it's that I'm careless and a little eager for success."

"I understand." Su Ho suddenly felt dull.

"This is my problem and I will fix it as soon as possible."

Su Xiaomu was stunned for a while, "What does this have to do with you?"

"This is a work style issue and a management issue, so it has something to do with me." Su Ho said.

"I'll take care of this."

Su Xiaomu: "..."

"I……"

"Okay, okay, I know, you didn't mean to blame me, you don't think it has anything to do with me, I know it all, stop talking about it, and do what you should do." Suho waved his hand.

Su Xiaomu nodded repeatedly, and then walked away.

Back in his office, Su Xiaomu completed the simulation and adjusted the Saoke.com program and compiled it in modules.

Resubmit to the supercomputing for pressure, simulated operation, etc. before going online for debugging.

Although it was more than once that it was great to have a super calculator, Su Xiaomu sighed again.

"Leaving this to supercomputer debugging is much faster than debugging the server..."

"Sure enough, if you have money, you can be willful."

At this time, Su Xiaomu finally remembered the firewall software he had written yesterday morning, and there was no problem in copying it, and it was compiled into software by modules.

Su Xiaomu couldn't wait to deploy it on the supercomputer.

Of course, the first place to deploy is the specially divided public network access area. Although there are a lot of access restrictions and a hardware firewall, as long as the public network is connected, there is risk.

Of course, Su Xiaomu was most concerned about this part. As the old saying goes, a thousand-mile embankment is destroyed by an ant nest.

This part of the public network area divided from the supercomputing is not completely isolated from the entire set of supercomputing physics, but is completely isolated logically, so it does not mean that it is foolproof.

Of course, after all, more than [-] million construction funds were spent, so it is relatively safe in theory.

What Su Xiaomu has to do now is to add a layer of double insurance.

The deployment operation is a fool's way throughout, and Su Xiaomu didn't realize something until the complete deployment was completed, "Hey, this firewall doesn't seem to pick systems..."

The vast majority of the world's Top500 supercomputers use the second-development Linux operating system. The main kernel is still Linux, but there is a certain degree of distinction from the conventional server Linux system.

The other part is the use of its own system. For example, several famous supercomputers in China have their own systems—well, they can basically be regarded as Linux.

But the supercomputer in the Mushu laboratory is not Linux, but Unix-like. Anyway, the kernel is relatively simple, but the operation mode is more complicated. If you just use the supercomputer to perform massive calculations, it doesn’t matter, there are auxiliary software available.

But Su Xiaomu just replaced the entire firewall module of the operating system. ①
"Ta Ma, I still need to take a closer look at the core algorithm structure of this retarded firewall." Su Xiaomu felt that he did not understand this firewall.

He still trusts the small garbage system, and the defense level of this firewall is still very high. After replacing the firewall modules in all areas of the entire supercomputer, Su Xiaomu rubbed his hands.

As for how to manipulate the firewall, he is more able to follow the instructions to get started, and he can't wait...

①: All operating systems have built-in firewall modules, and Windows Home Edition also has them, but people generally replace them with some convenient and easy-to-use software that can scan viruses.
