Siheyuan: I eat melons while doing scientific research

Chapter 1219 Run! ! ! (4k)

Gao Zhendong had installed this thing in his previous life when he was tinkering with Linux, but the source code was not stored on his phone, so he was still quite familiar with it.

As for why he wanted to bother with this, it was mainly because as a potential practitioner, Gao Zhendong once considered building a non-Windows productivity environment for himself. If he was just a programmer, it would be fine, but his major was not just about being a programmer.

The final result is that it can be used, but it is a bit awkward to use, which greatly affects efficiency. It is okay if you are in a hurry, and you can use it at a certain cost of time and efficiency, but if you are not in a hurry, it is more convenient to do things in the Wintel environment.

But on this line, there are no so many concerns, it's all new! Blank! Waiting for Gao Zhendong to fill it in. I'm the one who opens the door, and the ones behind me have to follow me!

It's very comfortable.

The only problem is that this version of the source code is 3.7MB in size, a double-sided 15cm floppy disk with a capacity of 270kB. After deducting the file system overhead, nearly 20 disks are required! ! ! !

Just the directory structure description takes up an entire floppy disk.

In addition to this description, other files are compressed packages in multiple volumes. Considering that source code mostly exists in the form of text documents, and the compression rate of text files is very high, these compressed packages are not small in size for current computers when they are decompressed.

Gao Zhendong looked at the compressed header file information, more than 18M!
Damn, Gao Zhendong felt that he was a bit greedy. Mainly, it was so big, and it wasn't quite right to say that he had done it all by himself.

However, it does not seem appropriate to go back and look for the earliest Octave 0.5 version. Firstly, the cost is too high, and secondly, the 0.5 version is not mature yet.

He carefully looked through the directory structure of the source code package. Fortunately, a considerable portion of it was examples, documents, tests, etc., which were not core and could be removed.

After removing these, the amount of code becomes slightly more reasonable.

Although it is still an exaggeration, Gao Zhendong cannot be judged by common sense in the eyes of his comrades, and he can "lie" about the timeline, so the issue of rationality can be circumvented.

For Gao Zhendong, there is not much left to do. This thing is also written in C language, which is very cool. Moreover, it was written at an early time, and the version of C language is consistent with Gao Zhendong's.

He decided to spend a few days to get this thing out. The main thing was to compile it in the current environment. It was impossible to get it done immediately. Even if there was enough time, it would not be easy to explain to the comrades who were working on the sound-absorbing tiles how this thing could be popularized so quickly.

He picked up the phone and called the 12th Ministry of Machine Building. He wanted memory, large-capacity memory. Hard disks were still under research, and there were only two ways to get large-capacity memory - either a dedicated extra-long tape, or stacking memory chips on the circuit board.

Both of these things need to be obtained from the 12th Ministry of Machine Building.

After hanging up the phone, Gao Zhendong calmed down and began to carefully study the Octave source code in front of the computer screen.

At the 12th Ministry of Machine Building, the leader signed the special approval note and said cheerfully, "It seems that Comrade Zhendong may have some good stuff."

The secretary took the note and said jokingly, "Why don't you go take a look first?"

The leader of the 12th Ministry of Machinery shook his head and said, "Well, it's boring to know too early. I'm just waiting for Comrade Zhendong to surprise us. That's interesting."

After saying that, both of them laughed.

Over the coast of North Jiaozhi, an F-105 that had dropped all its bombs was fleeing in the air.

The F-105 is a single-seat fighter jet. In fact, I feel sorry for the American pilots. They have to be responsible for flying, dropping bombs, and escaping after dropping bombs. It's really a busy job.

"Shit! Why is this fighter jet holding on to me? There are still some fighters behind that haven't dropped their bombs yet, go chase them!" The F-105 pilot complained frantically while turning his head to observe the chasing North Jiaozhi fighter jets in the air.

"SOB!! I would rather spend 1000 Citi dollars to buy a set of rearview mirrors that can see the back clearly!" The Citi pilot kept talking and spitting out sweet words.

It might be that the MiG-19 pilot from Beijiaozhi had just finished training and had not yet fully understood the concept that protecting one's own target was the most important goal in air defense operations. Eager to establish merit, he stared at the F-105 that had already dropped its bombs and chased it all the way.

The S2's Citigroup escort fighters are of this character. They are often lured away by a small group of Hans fighters, leaving behind a large bomber formation to be beaten by the Hans fighters that rush up from behind.

Fortunately, there were no air-to-air missiles at that time. The range of rockets, machine guns and cannons was limited. The American bomber formation could use the machine guns and cannons on the bombers to form a resistance firepower, so the losses were not so heavy.

The F-105 was running desperately in the front, and the MiG-19 behind was chasing desperately.

It is true that the F-105 is a fighter jet, but its relatively large and bulky body and the bombing mission it was carrying out at the time meant that it did not have much resistance to the MiG-19.

The two early-model Sidewinder missiles used for self-defense had long been used up in the fight with the Jiaozhi interceptor fighters, leaving it with only machine guns as its air combat weapon. Compared with the MiG-19 with two air-to-air missiles hanging under its wings, it looked like a helpless child.

The F-105 now only prays that the missile hung by the opponent is the original AA-2 "Atoll" of the Russians, rather than the CAA-1 from the Orientals. These two missiles look similar, but the Citigroup people are convinced that the CAA-1 from the Orientals is more difficult to deal with.

AA-2 is the name given by the Oceanic Treaty Organization to the Russian K-13.

CAA-1, the name given to our Raiden-1 by the Oceanic Treaty Organization, is now only used for export or to support friendly countries such as Jiaozhi.

As for Thunder-3, they haven't seen much of it.

Infrared air-to-air missiles do not require radar. In fact, the MiG-19's radar has weak performance and low reliability. Both the Orientals and the Jiaozhi people are reluctant to use it. Moreover, the control interface cannot command the Orientals' CAA-1. Therefore, although there was no harsh radar warning sound in the cockpit, the F-105 pilot still did not dare to bet whether the other side had launched a missile.

It didn't dare to use afterburner to escape at supersonic speed. To be exact, it didn't have enough fuel. The fuel consumption rate of turning on afterburner was like drinking water.

This made the F-105's designed top speed of more than 2.0 not work. He also wondered if turning on the afterburner would stimulate the opponent to launch the missile directly without completely locking on the target. Although the hit rate would be reduced, the F105 did not dare to take the risk.

The opponent's missiles have a high hit rate when chasing and attacking, and a speed of 2.0 Mach is not of much use in front of the missiles.

The pilot of the F-105 could only make a few maneuvers in the air from time to time, trying to avoid the missile that he didn't know whether it had been launched or not, which caused its accumulated energy to continue to accumulate and dissipate in a cycle.

Fortunately, the F-105 was faster than the MiG-19, which probably prevented the MiG-19 from finding an opportunity to launch.

The two planes chased and fled from the coast of Beijiaozhi to the sky above the North Bay.

The Citi pilot, who was escaping, took a look at the navigation instrument and discovered a serious problem. The radar tracking alarm sounded, and a dazzling red light flashed in the cockpit.

"F**k!!!" the F-105 pilot cursed.

In his desperate escape, he had lost his way and had flown to an area where entry was strictly prohibited - within 150 kilometers of the Oriental island in the North Bay.

He even went very deep, only about 50-60 kilometers away from the island. He was not very clear about the exact distance, but the number would not be too deviated.

While he was busy escaping, the F-105 pilot was able to quickly estimate this number based on the coordinate data on the navigation system, which was a demonstration of his superb skills.

At this time, in the radar station on the main peak of the island, the radar operator was reporting to the stationmaster.

"The two targets are still approaching our island at high speed! Judging from the radar signal, it seems to be a Citigroup F-105 and a MiG-19. The F-105 is in front, 55 kilometers away from us, and the MiG-19 is about 10 kilometers behind."

"They show no sign of turning back?" asked the stationmaster.

"no!"

The stationmaster gritted his teeth and said, "Send a warning broadcast and ask the superiors for instructions. Go to the missile launcher and connect the dual launchers!"

This radar is a supporting search and tracking radar for the air defense missile force. He is not only the duty station chief, but also the duty commander of the air defense missile force on the island.

This is when the advantages of solid fuel missiles are revealed. There is no need to refuel, and there is no need to consider waste or maintenance troubles. All you need to do is connect the power supply.

Among the several tracked launch vehicles around the top of the mountain, the missile launchers on two vehicles were pointing straight at the sky. Suddenly, they moved slowly and pointed towards the southwest.

The vertical launch was not yet ready, and the launch racks on the tracked launchers were a bit of a makeshift transition. Each vehicle had a launch rack with a steel tube frame, and each launch rack carried two missiles whose wings were not even folded. The wings arranged in a ten-X shape were very obvious.

It is said that two launchers are connected to the power supply, but for the sake of reliability, the two launchers are connected to the power supply on two launch vehicles. It is also reasonable to say that four launchers are connected to the power supply. After all, there are two planes in the sky. And simply connecting the power supply will not have any side effects on the missiles. The worst that can happen is that the power will be cut off and the missile will not be fired.

At this moment, a broadcast from a public frequency band sounded in the cockpit of the F-105.

"...Unidentified flying object, you are now approaching our air defense zone. Please identify yourself immediately and leave our air defense zone, otherwise we have the right to take further action..."

I couldn't understand it. I couldn't understand it at all! The pilot of the F-105 knew nothing about our language, but he could guess that it was a warning to him. However, he had no idea about the content and severity of the warning.

He didn't understand, but the MiG-19 behind him did. Just kidding, he was trained by listening to this language, how could he not understand it? In fact, it was quite familiar to him.

He immediately pulled the stick and rudder, and the plane began to turn in the air.

"Hello, comrades. I am a fighter from the Jiaozhi XXX unit, and I am chasing the Citigroup enemy aircraft. As requested by the comrades, I will terminate the pursuit." His idea was to hover outside the air defense zone to see if he could catch the F-105 that was forced out.

The comrades in the radar station felt very cordial when they heard the slightly unfamiliar Chinese voice coming from the radio. However, no matter how cordial they felt, in principle, no one could enter the air defense zone unless it was their own aircraft. So the comrades did not say anything like "It's okay, you continue to chase."

"I understand." It's a very simple answer, but it contains rich connotations.

At the same time, the response to the request to open fire from the Cape City Command had already returned to the radar station.

The answer was clear: "Once you are within missile range, you can open fire."

When fighting a war, why bother looking ahead and behind? The Russians in the 21st century have a deep understanding of the consequences of looking ahead and behind when fighting a war. The war will become a mess, and you may even suffer a heavy loss and lose face.

Moreover, there is no strict legal basis at present. We are not a signatory to the Convention on the Law of the Sea at this moment. Coincidentally, Citibank is not there either. As for the explanation of under what circumstances an attack may be launched, the main approach is that you say yours and I say mine.

What’s even more coincidental is that the United States does not recognize us, which makes it even more difficult to be selected.

The shooters of the surface-to-air missile battalion were all excited and eager to try, especially the shooters who were selected to connect the power to the launch vehicle. There were many launch units here, and although not all units were equipped with the same launch control vehicle, one launch control vehicle could still manage several launch vehicles.

Comrades are now looking forward to the other side flying into range!

At this time, the guidance radar had already established a stable track on the enemy plane. The comrades looked at the light spot that was approaching little by little on the radar screen and the numbers that were decreasing little by little, and they were very anxious.

In the cockpit of the F-105, the increasingly rapid radar lock warnings made the pilot upset. He could not see through the thick clouds to see what was happening on the sea, but he did not dare to turn, as it would be very dangerous to expose his side and rear to the pursuing fighters.

The F-105 pilot looked back again.

"Thank God!" This glance made him overjoyed.

The MiG-19 that was following closely behind us has disappeared!

Hahaha, God help me, I finally got rid of this god of death.

In the cockpit, the warning broadcasts we sent on the radio's public channel were intertwined with radar lock alerts and the pilot's laughter.

"Haha~~~!!! Holy Shit!!!" The Citi pilot, who had just laughed a few times, suddenly realized something. Like a duck with its neck strangled, his laughter stopped abruptly, and was replaced by a chill rising from the bottom of his spine and cold sweat all over his body.

The Cochin aircraft did not lose track, but understood the Orientals’ warning!!

He left on his own initiative!!

The actions of the MiG-19, no matter how it is explained, are extremely dangerous to the F-105!
Perhaps it was because the air defenses on this island were extremely powerful and dangerous, and another possibility was that the other side was very confident in handing themselves over to the Orientals.

He glanced at the navigation and flight map and discovered that he was less than 30 kilometers away from the island!
run!
