Reborn Tech Maniac

Chapter 907 How Advanced Tang's Programming Skills Are
……

There is only one year left before the return of Xiangjiang, and the intensification of the situation is self-evident.

For example, in terms of personnel, the British civil servants in the Hong Kong government have retired early and returned to their homeland; and the Qinhe line, which has transformed from the old British foreign company Jardine, will inevitably be affected by some restlessness.

Although full preparations have been made for a long time ago, the face-saving project of buying people's hearts still needs to be managed-the richest man specially held a meeting for this purpose.

After waiting for it to end, Zhou Mi intentionally left chatting and casually said, "You've been quite aggressive these days."

Tang Huan said with a smile: "I'm also afraid of being missed by people who don't follow the rules-of course I have to wipe it off quickly."

Zhou Mi joked: "So you also have something to be afraid of."

"Believe it or not, you are also on their minds? It's just that it hasn't had time yet." Tang Huan said leisurely: "You should have heard how much money Li Bancheng was extorted, right? Bold, how productive is the land?"

"It seems that everyone should thank you for your anti-violence and safety." Zhou Mi laughed and said, "But, how did I hear that Li Bancheng's 10 billion in cash was not saved after all, and all of it was spent?"

"Perhaps Li Bancheng is superstitious and feels that this money is already unlucky and it is not appropriate to keep it." Tang Huan casually guessed, "Didn't it mean that he has already invested the money in the company of his youngest son?"

Zhou Mi sighed, "I'm just reminding you that the situation in Xiangjiang is very delicate, especially during the period before the reunification - everyone doesn't want to make waves on the flat ground."

"Don't worry, I understand this." Tang Huan nodded, "Don't you know my style? Convincing people with virtue - I'm also promoting Bitcoin in private, definitely before letting others into the pit , go into the pit first."

Zhou Mi asked doubtfully: "This Bitcoin, I think the role of money laundering is becoming more and more obvious - what do you think?"

"It's only just started, so you've already labeled it?" Tang Huan shook his head, "Only when time goes by can we get a better understanding of this innovative thing."

Zhou Mi pondered and said: "I suggest you to put aside the affairs of Xiangjiang for a while, anyway, there is me, so that the public opinion will cool down."

"Listen to people's advice and have a full meal." Tang Huan nodded slightly, "The European Space Agency's Ariane 5 launch vehicle is about to launch its first launch—I have received an invitation to go over to see the excitement."

……

The warming of Western European countries is reflected in many aspects. In addition to the most famous political and economic organization - the European Union, cutting-edge scientific research institutions are also formed together. For example, the world's largest particle physics laboratory with close contacts with Tang IT - — CERN.

Similarly, the European Space Agency, headquartered in Paris, France, is also a multinational organization - so far, there are 14 members in total.

Among them, France contributed the most.It offers the home of the European Spaceport - French Guiana on the northern Atlantic coast of South America, bordering Brazil.

The rare thing here is that it is close to the equator, only 5 degrees north latitude, which is of great benefit to rocket launches-the low latitude greatly shortens the distance from the launch point to the orbit point; the orbital inclination angle of the same launch azimuth is small, and the apogee changes orbit The energy required is small, thereby increasing the payload of the synchronous orbit; at the same time, there is a very wide launch arc on the sea to the north and east; in addition, the population, traffic, and weather conditions are also ideal.

NASA's most important launch center, the Kennedy Space Center, has a similar approach to the site selection.Located on Merritt Island on the east coast of Florida in the eastern United States, it has a north latitude of only 28 degrees; and the Wenchang Space Launch Site, which was opened by China more than ten years later, has a north latitude of 19 degrees.

The European Space Agency works in a wide range of areas - the research and development of the upcoming Ariane 5 rocket is a major project it is responsible for.

In fact, the proposer of this series of rocket plans is France, and its deeper roots can even be traced back to the late Second World War, when the Allies plundered and conquered Germany's rocket technology achievements.The related technologies obtained by France are mainly V2 rockets.

The degree of resource consumption in the aerospace field can be guessed without much thought. If everyone shares the share, it is naturally cost-effective, and the gradual maturity of the structure of the European Space Agency in the 1970s provided this opportunity, so the French National Space Research Center put The Ariane rocket was transferred to the European Space Agency.

顾名思义，阿丽亚娜5号运载火箭之前，还有1号、2号、3号、4号，节数都是3。

阿丽亚娜1号运载火箭的第一次成功发射时间是1979年12月24日，为基于导弹技术研发的三级运载火箭，之后的阿丽亚娜2号运载火箭、阿丽亚娜3号运载火箭、阿丽亚娜4号运载火箭，都属于它的改进型号。

In terms of geosynchronous transfer orbit payload, the Ariane 1 launch vehicle reached 1850 kilograms; a total of 11 launches were launched, and 9 were successful.

1987年11月20日第一次成功发射的阿丽亚娜2号运载火箭，地球同步转移轨道酬载量达到了2180千克；总共发射了6次，成功了5次。

1984年8月4日第一次成功发射的阿丽亚娜3号运载火箭，地球同步转移轨道酬载量提高到了2700千克；总共发射了11次，成功了10次。

1988年6月15日第一次成功发射的阿丽亚娜4号运载火箭，可靠性进一步提高，最大地球同步转移轨道酬载量更是达到了4300千克——目前仍在服役。

It can be said that the performance of these types of Ariane launch vehicles is not satisfactory in terms of payload, for example, it is inferior to China's Long March-[-] launch vehicle.

Therefore, high hopes are placed on the newly designed Ariane 5 launch vehicle. Its research and development took ten years and 70 billion yuan, and the minimum payload capacity of the geostationary transfer orbit has reached about 6100 kilograms.

The Ariane launch vehicle is funded by 10 shareholders from 24 European countries. It can be said that the interests are evenly shared, so it has attracted great attention.

Tang Huan is also very interested in the launch vehicle itself. Gein's current launch cost is cheap in the tens of millions of dollars, and if the Ariane 5 launch vehicle is successfully launched, that means, The addition of an option in the international market is definitely a lot of benefits.

Even in order to get close to the European Space Agency, which employs thousands of people and has an annual budget of billions of dollars, the richest man does not have to go all the way to French Guiana in South America. He only needs to visit the European Space Agency in France. The headquarters in Paris will do.

With everything in place, the countdown to the Ariane 5 launch began.

Tang Huan and others at the European Space Agency headquarters in Paris, France, can clearly see the scene of the European Space Launch Center in French Guiana on the big screen.

At 12:34, the Ariane 5 carrier rocket ignited, dazzling flames spewed out from the bottom, and the rocket left the ground and soared into the sky.

After 5 seconds, everything works fine.

After 10 seconds, everything works fine.

After 20 seconds, everything works fine.

After 30 seconds, everything works fine.

……

Inside the headquarters of the Arianespace company in the southern suburbs of Paris, the tension and excitement are clearly increasing in the ratio of the latter.

Some people, like Mr. Richest Man, who participated in the satellites carried by this launch, also whispered with ease.

……

After 35 seconds, everything works fine.

Suddenly, the rocket that was originally streaking straight through the sky unexpectedly deflected 90 degrees to the left, changing its attitude from vertical to horizontal, and then exploded into "fireworks" that filled the sky.

Gene Luton, the general manager of Arianespace, which operates and sells the Ariane rocket, suddenly looked ugly-the rocket carried a communication satellite worth 5 million U.S. dollars.Including the rocket itself, $6 million was burned in the blink of an eye.

Such a tragic scene not only made the people at the Paris headquarters feel like mourning, but also the tourists at the European Space Launch Center in French Guiana, as well as the countless viewers watching the live TV broadcast, all sighed with regret - this firecracker is really expensive!

……

When shaking hands and saying goodbye, Tang Huan said to Gene Luton seriously: "As far as I know, the programming language used by the software control system of the Ariane 5 launch vehicle is Ada. He has rich experience, and if possible, he is very willing to contribute a little to the accident analysis.”

"Thank you Don for your kindness." Gene Luton replied with a sad face, "We will think about it carefully."

……

For the failure of the first launch of the Ariane 5 carrier rocket, among those who grieve, the richest man is definitely not on the list.

Therefore, Tang Huan, as usual, eats, drinks, and plays when he needs to - this year's French Open, Steffi Graf once again entered the final, so he happened to enjoy it.

Now, there is only one thing that can defeat the queen of tennis, and that is the injuries accumulated over the years in her career. Although the richest man took many precautions when Steffi Graf was growing up, the laws of nature are the laws of nature.

Fortunately, Steffi Graf's injuries this year are not obvious, and her competitive state is also quite good.

According to this trend, Steffi Graf has almost no problem surpassing those career historical records set by tennis predecessors such as Margaret Court in the early years.

During the chat, Jin Xing and Jin Guo, who are the strongest among all the sons of Tang in the same age group, even though they have just turned 5 years old, shook Tang Huan's arm, pointed at the TV, and kept asking curiously, "Dad, Dad Why, halfway through the flight, did the rocket turn around and explode?"

The richest man smiled and said: "Not only do you want to know, but now everyone wants to figure out what is going on, but unfortunately, the reason has not been found yet?"

The child who thought that his father was omnipotent asked naturally, "Father, why are they so stupid, why don't you ask for your help to find the reason?"

Tang Huan laughed heartily, "Who knows? Maybe they want to keep technical secrets, or maybe they can't save face..."

……

Arianespace, which operates and sells the Ariane rocket, is funded by 10 shareholders from 24 European countries.Among them, France has the largest number of shareholders, with a shareholding ratio of more than 7%; followed by Germany, with 60 shareholders, and a shareholding ratio of more than 2%; followed by Italy, Belgium, Switzerland, Sweden, Spain, the Netherlands, Norway, Denmark.

It is of course convenient for everyone to cook together, but once the food is cooked, there will be a lot of confusion. It is not so easy for every shareholder to accept failure calmly.

Under tremendous public relations pressure, all partners of the Ariane 5 launch vehicle, including the European Space Agency, the French National Space Research Center, Airbus Group, and Arianespace, quickly made a unanimous decision. Introduce an authoritative third party to assist in the accident investigation, so as to give everyone a clear explanation.

As a result, Tang IT, who had taken the initiative to say hello before, naturally became a guest of honor.

Mr. Richest, who was holding a small tennis racket to amuse the children, was not pretentious when he got the invitation, and immediately said happily that the most elite technical team would be here soon.Before that, let me take a rough look at the software code of the control system.If the investigation can reveal the truth before the final of the French Open, everyone will appreciate it in a relatively relaxed mood, right?
17 years ago, he developed the world's first spreadsheet program CGrid. Tang Huan, known as the "father of spreadsheets", has always been recognized as a big star in the programming field. But there is no trace of the works, and I don't know if Jiang Lang's talent is exhausted.

In fact, of course, the richest man has not forgotten the housekeeping ability to bring himself the first pot of gold. Take Zheru's own programming and development general environment—Zerone_Development_Workshop as an example, and he is very familiar with it!
Accompanied by the staff, Tang IT used Zerone_Development_Workshop to import the Ada language code of the Ariane 5 launch vehicle.

Although aerospace is a huge project, it does not mean that the computer embedded system used is allowed to be bloated-you must know that in space, energy is extremely precious, and any action must be efficient.

Although there is a lot of software code for the Ariane 5 launch vehicle control system, it is really not as big as the Zheru office software suite.

Tang IT casually typed a command to let Zerone_Development_Workshop highlight and track the conversion codes of different data types.

Not long after, he pointed to one place and said earnestly: "The conversion from 64-bit floating-point numbers to 16-bit integers here is very suspicious!"
