"As for other designs, I actually have a lot of plans for the future, I want to build two twin towers of more than 100 floors in Central, which will be used as the global headquarters of Jade Emperor Group. Huh

I'm also planning to build a super hotel on Hong Kong Island. ”

Zhang Zhonghua said politely.

"There is no problem with building a 100-storey twin tower in Central, is this plan of yours in a hurry?"

"It's not in a hurry, it can be any time, how tall can a building be built in Central? Can you bear it? ”

Zhang Zhonghua asked curiously.

"I have inspected Hong Kong Island before, and considering the typhoon and the condition of the foundation, it is not a big problem to build a building of 5 or 600 meters in Central.

However, Central should not be built too high, which will affect the lighting and ventilation of other buildings, and there will be many problems in the future. "Huh

Pei Luming said.

Five or six hundred meters? It seems that the Central side will definitely not work, but in Kowloon it should be possible, but this will have to be talked about later, not to mention eight or nine hundred meters now, five hundred meters is the world's tallest building.

The two talked for a long time, and then Zhang Zhonghua also said goodbye and left, Master Pei Luming still needs to reverse the jet lag, as long as people arrive on Hong Kong Island, it is easy to say, even if Master Pei Luming takes the team out for a week first, Zhang Zhonghua does not say a word.

After Zhang Zhonghua accompanied Pei Luming's team to Nanlang Mountain for a field trip, the wharf built by the Hong Kong government in Nanlang Mountain has been completed, and the construction of the highway is also being stepped up, and the progress is still good.

During this period, Jade Emperor Daily and Sing Tao Daily were also officially ready to enter the Toei market, with Sing Tao Daily publishing an English daily newspaper and Jade Emperor Daily publishing a Japanese version.

The newspaper sales channel of Homemart convenience store is also officially open to other newspapers and magazines, and the newspapers on Hong Kong Island have long coveted the convenience store channel.

At the same time, in Washington, the capital of the ugly country, the people of the ugly country held a march against the war of aggression against Vietnam. Huh

And Zhang Zhonghua and his bodyguards also took the plane from Kai Tak Airport to Chouguo, he hasn't been to Chouguo for a long time, and he still needs to show up often.

Zhang Zhonghua's plane made two stops in Tokyo and Alaska, and finally arrived in San Francisco after a long trip, and then found a hotel in Palo Alto, where Stanford University is located.

After inspecting the branch of the ugly country, he was invited by IBM Watson Jr. to participate in the cocktail party.

At the reception, Zhang Zhonghua saw many old acquaintances, and even some officials from the Ministry of Defense of the ugly country.

Zhang Zhonghua tentatively proposed to visit APANET, but he didn't expect the officials of the Ministry of National Defense to agree immediately, which made Zhang Zhonghua a little unresponsive.

According to the agreed time, Zhang Zhonghua came to the predetermined place.

"Mr. Zhang, welcome to you, I'm Chris Watson." Huh

"Hello Mr. Watson, I am honored to be able to visit this great project."

The two exchanged pleasantries, and then began to visit ARPANET, led by Chris Watson.

"Mr. Zhang, the Advanced Research Projects Administration of the Ministry of National Defense of the People's Republic of China started a plan a few years ago to build a network for interconnection and data sharing, and it was not until the end of last year that it began to bear fruit.

At present, there are only four nodes in this network, which are distributed in the University of California, Los Angeles, Los Angeles, California, Santa Barbara, Stanford University in San Francisco, and the University of Utah in Utah, four mainframe computers.

The ARPA network uses a wireless packet-switched network and a satellite communications network to connect the mainframe computers of these four nodes, as well as a packet-switched network. ”

Chris Watson introduced.

Zhang Zhonghua still knows a lot about the origin of the Apa net, and there are still a few nodes that should be connected to the Ministry of Defense and important military bases of the ugly country. Huh

In a sense, the Apa net is a product of the Cold War between the United States and the Soviet Union, and the 60s were a very special era for ugly countries.

A few years ago, Cuba also had a nuclear missile crisis, and the Cold War between the ugly country and the woolly bear quickly heated up, and the threat of nuclear annihilation was too terrifying.

At the same time as the blockade imposed on Cuba by the ugly countries, the Vietnam War broke out, and many third world countries experienced political crises.

The top level of the ugly country believes that whether or not we can maintain our leading position in science and technology in the world will determine the outcome of a military war. The progress of science and technology is greatly dependent on the development of the computer field, and the idea of interconnection and sharing of data in computer centers has developed rapidly.

If the ugly country has only one centralized military command center, if this military command center is destroyed by the nuclear weapons of the original woolly bear, the military command of the ugly country will be paralyzed, and the consequences will be unimaginable.

Therefore, a decentralized command system is designed, which consists of scattered command points, and when some command points are destroyed by nuclear weapons, other points can still work normally.

ARPANET originated in the military field and was also a network for the secret service of the military, and later began to develop rapidly because of the convenience of data transmission and sharing. Huh

"It's really amazing, it's very difficult to realize data packet exchange with today's technology, but in the future, if the whole world can be connected, it will be much easier to work and research."

Zhang Zhonghua praised. It's still exciting to think about it, and this year ARPANET should have begun to expand.

In 1973, ARPANET would begin its international development;

In 1984, ARPANET became the Internet;

In 1986, the world began to lay submarine fiber optic cables; Subsequently, the ugly country began to allocate IPv4 root servers.

Several computers are connected to achieve data sharing, which is called a local area network;

Computers throughout the city are connected, and this is the metropolitan area network; Huh

Laying fiber optic cables between cities and connecting cities is the backbone network;

These backbone networks are interconnected across the country, and then connected to foreign networks, which is the Internet.

The Internet still has more than 10 years to develop and take shape, and it is very troublesome not only to establish a large-scale backbone network, but also to improve various network protocols.

Zhang Zhonghua sighed while visiting, although it is still very simple, but the technology of the ugly country is really too developed, and it is the world's first in this era.

If you want to build an ARPANET, you need at least thousands or tens of thousands of computer experts, and in today's era, there is no one in the world except for ugly countries that can be built, and science and technology are the primary productive forces.

Chris Watson also invited Zhang Zhonghua to operate on the mainframe computer, the UNIX system is still running relatively smoothly, and there are slight problems with the IMF database and compression software, but they are not major problems.

Zhang Zhonghua also understood why the Ministry of Defense agreed to visit APA so easily, it turned out that the compatibility of various software is not very good, Zhang Zhonghua and his software companies continue to optimize the software. Huh

Nima, the compression software Lao Tzu has been sold to IBM, and Lao Tzu still wants to contribute?

However, Zhang Zhonghua had no way to refuse, people had to bow their heads under the eaves, and he still had to mix in the ugly country and earn money from the ugly country.

The two then discussed the issue of compatibility and upgrade of the UNIX system, the C language and the IMF database, and then Zhang Zhonghua left the Stanford University laboratory where ARPANET is located with a few tapes.

"Boss, this APA network is really powerful, if it is promoted, it will be too convenient to share resources in the future."

Henry Morey sat in his car and began to fantasize about the future of ARPANET, and it would be hard to imagine that the western part of the ugly country would be able to access the large computer files in the east at any time.

"It will indeed be very convenient, but this is not a short time to achieve, I am afraid it will take a long time, at present, the ARPANET is mainly for the military, it is difficult to carry out commercial use without ten years, and the cost of satellite communication is not affordable by ordinary companies."

The territory of the ugly country alone is so large, it will take years to build a network, and the cost may not be cheap. "Huh

】

Dimitri Zverev thought for a moment and said.

"However, it cannot be denied that the prospects of ARPANET are very far-reaching, and it will be more convenient if global networking can be implemented, but this may be more than ten years away."

Zhang Zhonghua said with emotion.

He can't wait for the arrival of that era, big data, cloud computing, artificial intelligence, etc., Java, J2EE, PHP, Python, etc., when the time comes, he will be the god of the Internet.

"It's not very difficult to achieve global interconnection, it's rare to communicate protocols, which have a lot of difficulties to overcome, and data transmission is too slow and not very applicable."

Dimitri Zverev said.

"There are so many things involved, and global interconnection also needs to build some data centers distributed on several continents around the world." Huh

Listening to some of the theories narrated by Zhang Zhonghua, two computer doctors, Dimitri Zverev and Henry Morey, were also eye-opening.

I just feel that the boss is really awesome, and some theories are very advanced and completely in line with the development of technology, which makes them breathtaking.

Both of them also feel a little ashamed of themselves, does the boss really only have a high school education? This is simply the pride of the computer field.

"Our UNIX system, C language and IMF database don't need to change much, just modify the communication protocol, it should be very fast, and the follow-up only needs to be patched."

Henry Morey looked at the boss with admiration, it was almost completely compatible with the TCP/IP protocol of the Ministry of Defense of the ugly country, and the boss's programming level was really beyond reach.

"Let's study it, it is estimated that it will be submitted to the Computer Association of the ugly country in half a month, and we are mainly compatible with IBM equipment."

When Zhang Zhonghua said this, he inevitably remembered Dr. Wang An, who had been stumbling with IBM all his life, but it was not compatible with IBM equipment, and his arm could be twisted over his thigh. Huh

Thinking of this, Zhang Zhonghua sighed deeply again, is the hatred between scientists so great? Is it really difficult to mediate?

However, the hatred between scientists is really a bit too terrifying, thinking of the love-hate relationship between IBM and Wang An, Zhang Zhonghua remembered the story between Edison and Tesla, how can these two not be mortal enemies.

The whole world knows that Edison is a very famous inventor, but little attention has been paid to Tesla, and most people only learn about this person. Even the name Tesla is familiar to the world because of Musk's electric car.

But in fact, Tesla's invention was no worse than Edison's, and even became Edison's sworn enemy, which made Edison constantly suppress him.

Tesla worked under Edison in his early years, and Edison funded him a lot, but Edison said in his later years that his biggest mistake was that he never respected Tesla.

Tesla has a very strong memory, can memorize the entire book he has read, and has a lot of imagination and creativity.

Later, Tesla left Edison because he was not respected by Edison, and later Tesla also invented the asynchronous generator to solve the limitations and troubles of the direct current system. Huh

Tesla has been learning all his life and has a great passion for science and technology, and it is said that he has an ability called "photographic memory", which is to write down the contents of a book directly after reading it, and then put the knowledge in the book into practice in his mind.

Edison, on the other hand, spent most of his time looking for patents that could bring wealth, and he did whatever it took to get them.

Edison was best known for obtaining patents through violence, such as when he hired a group of thugs to destroy other people's laboratories in order to get the patent for the invention before anyone else.

However, in order to suppress Tesla, Edison also used more frenzied means, such as in order to prove that the alternating current invented by Tesla was harmful, so he deliberately designed an electric chair to make a subject be electrocuted alive on it, and this is also the first time that the electric chair was used as a torture instrument in history.

Tesla and Edison were both developing X-ray fluorescence analyzers at the same time, but in order to get the patent faster, Edison did not hesitate to let his assistant be exposed to X-rays for a long time, which eventually led to his assistant's death from cancer.

Tesla helped Edison fix his DC motor, and also improved the motor to make it more efficient, which in turn helped Edison make more money.

However, despite this, he did not pay Tesla $50,000 for repairs until Edison's death, so this incident became a major reason for Tesla and Edison to part ways. Huh

Although Edison later offered to raise Tesla's salary from $18 to $25 a week to keep him, Tesla eventually left and founded his own company, which began to become a sworn enemy of Edison.

In Edison's later years, he once said that Tesla was the person he respected the most. However, it is a pity that when Edison said this, he had already spent most of his life dealing with Tesla, and because of Tesla's death, he was full of loneliness, and Edison's death was full of wealth and honor.
