Chapter 674: Being able to harvest the wool of the 21st century (two chapters first)
Seeing Gao Zhendong’s extremely confident look, others didn’t know it, but at least Chief Engineer Chi of the computing institute believed it.
"That's okay. You can finish the first version of the source code and leave the debugging work to us."
Chief Engineer Chi also knows that, normally, The process of writing source code itself includes debugging. Once the source code is written, debugging is mostly completed.
But in Gao Zhendong's case, it's hard to say. He said that he wrote the source code and had others debug it, so it would be possible for him to complete the source code without completing the debugging.
But this matter is a bit too scary for other comrades.
If nothing else, just listening to the list of functions Gao Zhendong just mentioned, you know that this thing sounds good, but it is also really difficult to implement.
At this time, unlike in the future, Ctrl+C and Ctrl+V can solve more than half of the problems, and some classic problems have complete solutions from answers to analysis.
In half a month, ordinary small software may not be possible, let alone such a large system.
If Gao Zhendong demonstrated his strong theoretical foundation, system design experience, and understanding of computer software and hardware when he planned and introduced the database, then Gao Zhendong’s words now make him They learned that he also had extremely strong practical and software programming abilities.
If either of these two abilities can appear in a person, that person must be a leader in the industry, and if both are available, it is even rarer.
But to their surprise, apart from Gao Zhendong, Chief Engineer Chi of the computing institute who was most familiar with the software and most likely to raise objections said the same outrageous words as Gao Zhendong.
No, you believe whatever he says, right?
Chief Engineer Chi: Well, I really believe it.
Hearing what he said, Gao Zhendong knew that he didn't have to worry about this matter, and their computing center would naturally handle it safely.
Seeing Gao Zhendong nodding in approval, Chief Engineer Chi turned to look at the comrades from several economic and trade schools.
“Comrades, in terms of the preparation of computers and system software, we have calculated all the experience that we have had with Professor Gao in debugging and improving large-scale system software such as operating systems. In terms of the preparation of large-scale software such as database systems, we should There are certain advantages, so this matter , Our computing institute is responsible for the debugging of the database source code, let’s take the lead.”
Although Chief Engineer Chi was very humble here, he turned around to face other comrades. In the professional direction of computers and software, he is not polite at all.
The words may be polite, but the meaning is completely different.
There is only one core, and our computing department has done this good thing.
Comrades from the Statistics Department and the Ministry of Foreign Commerce have no objections to his words. Originally, comrades from their own economic and trade schools said that it might be okay to develop some statistical and economic application software, but this kind of system sounds like a big project. For universal basic software, the top technical institutions in the country, such as the Institute of Computer Science and Technology, must develop it before they can rest assured.
This is not the time to protect others. In front of the computing center, comrades from economic and trade schools can cooperate, but leaders cannot do it.
As for why such a big project is only worth fifteen days to Professor Gao, that is Professor Gao's ability.
At least for the comrades of the Ministry of Foreign Commerce, they believe whatever Gao Zhendong says in this regard.
The Statistics Department and Gao Zhendong are not actually familiar with each other, but it doesn’t matter. There are comrades from the Ministry of Foreign Commerce who are supporting us. They all believe it, so why don’t we believe it?
After they listened to Chief Engineer Chi's words, the comrades from the Statistics Department smiled and said, "Well, if a professional institution like yours takes action, then we can rest assured. Our department, as well as the comrades from colleges and universities who have undertaken relevant work, will definitely do a good job." Cooperate. ”
It’s okay for you to take the lead on this matter, but don’t forget about the comrades in our schools.
Comrades from the Ministry of Foreign Commerce are even simpler. In this matter, they are the introducers. They just organize the strongest relevant forces together, and enjoy the results by the way.
Facts have proved that they took this step correctly. As soon as Comrade Gao Zhendong made a speech, he made this matter clear and clear, and took the fire out of the pot.
Once successful, this matter will no longer be a problem in the future, at least for a long time.
What to say about failure? Even if it doesn't succeed, Gao Zhendong's plan is still the best plan. If it doesn't work, then we should settle for the next best thing. For example, he and Chief Engineer Chi of the computing institute have also mentioned the method of establishing data standards.
Several comrades from economic and trade schools also have no objections. They know their own affairs. This thing is not that simple at first glance. Although Professor Gao said it was relaxed and happy, he could get the source code in half a month, but Others may not have what he has.
Several of my colleges said they had experience in application software in the past, but in fact they only did a little bit of simple statistical application software compilation work. When it comes to experience in such large-scale system software, and computing Compared with that, it is naturally beyond the reach of a horse.
It is very satisfying to be able to follow Professor Gao and the professionals from the Institute of Computing to gain some software qualifications and share some achievement honors.
Comrades from several colleges and universities have stated that they will give full play to their relevant work experience and cooperate with the debugging of the database management system.
For comrades working on software in economic and trade schools, this is the best opportunity.
I am not the best software person, that doesn’t matter. I am the best software person among the economic comrades, and that is enough. The next step is to discuss specific work arrangements between the Institute of Statistics, the Statistics Department, the Ministry of Foreign Commerce, and the universities.
Gao Zhendong didn’t have much control over this matter, although basically every time something was determined, Chief Engineer Chi would ask: “Professor Gao, do you think this arrangement is appropriate? ?”
Gao Zhendong basically nodded. He is not involved in these details, so you can decide it yourself.
Returning directly from the Ministry of Foreign Commerce, Gao Zhendong said hello to Lou Xiao'e who was cooking, and then headed into the south room.
Although it is an extremely huge workload to tailor the open source database source code to one that can be used by the current DJS series computers. To some extent, it is even more difficult than writing a new one, but it is highly Zhendong saw something else in the system store. With this thing, he could cheat.
It can only be said that these small shops around the school sell everything. Especially when some students who have worked hard to make money in school join in, things become more interesting.
What he saw was a USB flash drive. The introduction of the USB flash drive was very interesting.
"Database source code. This is a senior who runs a print shop and collects downloaded source codes of all major historical versions of an open source database for his junior students. The kind-hearted senior even only charged them 50 yuan Money.”
This kind of situation is rare. By the time Gao Zhendong traveled through time, who the hell wouldn't know how to download something by himself.
But the birds are bigger... On the contrary, the woods are bigger, and there are all kinds of birds.
Even if some people don’t know where to find these things, or are too lazy to look for them, they can directly use their money power. After all, they can get all the major historical versions, which is not a small workload.
It’s just that this kind of thing is not that common. Usually seniors who open printing shops will only do it after receiving orders. Gao Zhendong can only find it occasionally.
This is what he relies on for cheating.
There is no such thing as adaptive transformation when acquiring knowledge from the system. If you understand something, just learn it. If you don't understand it, just do it.
But extracting items from the system store is different. Gao Zhendong can get a bug.
The system describes this thing as "database source code" instead of "U disk". Obviously, in the system judgment, it recognizes the "source code", which means that this thing mentions What comes out and undergoes adaptive transformation is the "database source code"!
As for whether EEPROM can be used in ordinary U disks, Gao Zhendong has tried it. When a U disk is used, it must be a tape, not an EEPROM. Even one-time writing will not work. It seems that now The technology cannot yet support the production of ROM.
There is also a possibility that the system defines the USB flash drive as "removable memory" rather than "rewritable chip storage".
In short, the EEPROM cannot be extracted from the USB flash drive, so we have to give up.
With the above bug, I feel very comfortable. The system transformation is simple and quick, and can be done immediately.
There is absolutely no need for Gao Zhendong to rewrite it himself.
If he hadn't been afraid of scaring the other comrades at the meeting to death, he would have even dared to say, "I'll give it to you tomorrow."
But doing it that way was too scary and there was no way to explain it, so Gao Zhendong had no choice but to settle for one and a half months.
After starting the extraction, what appeared in Gao Zhendong's hand was a tape. This time, there was no paper material.
This bird system is very stingy.
Insert the tape into the tape machine and read it on the DJS-61.
Gao Zhendong browsed it and found that the source code was very complete. It also came with an instruction manual for the database management system. Fortunately, when he saw that there was no paper information, Gao Zhendong thought the instruction manual was gone.
The originally powerful open source database has been downgraded into something similar to FoxBase.
FoxBase is an ancient relational database system popular under DOS around the 1980s.
Simple is simple, but it has the basic functions and is still in command line mode.
The DJS-61 is like this now, no matter how complicated it is, it can’t stand it.
To be honest, this simplified version has reached its current peak, but when it comes to functionality, it actually lacks the original source code in the USB flash drive.
Thinking of this, Gao Zhendong immediately solidified the qualification to extract this "database source code USB flash drive" with his backhand, solidifying this thing, and the wool can be harvested until the 21st century!
When there is a new type of computer, let’s just mention it. Wouldn’t it be nice to keep up with the latest computer developments and update the version of the database management system!
