Chapter 357 "Writing is like meeting in person"

Gao Zhendong didn't know about these things, he just took a quick look and thought, well, Old Xie went up, haha.

As for the rest, there is none. For example, Xu Damao's bangs are not something he can even think of.

He still holds the post of deputy chief of the training department, although he is now at the same level as Director Zhang of the security department. He knows that there are always exceptions to these matters, so there is no need to delve into them.

When he arrived at the office, he first called the computing center.

When Chief Engineer Chi answered the phone and knew it was Gao Zhendong, he started to congratulate him: "Chief Engineer Gao, congratulations, everyone is a chief engineer now. You have been promoted, how come you forgot about these old friends? I haven't heard from you for a while."

It wasn’t that long actually, but it’s just a joke, you can say whatever you want.

Just like Gao Zhendong, the chief engineer, is of a lower rank than his chief engineer, it does not prevent him from saying that they are all chief engineers.

Gao Zhendong laughed: "Chief Engineer Chi, you are wrongly accusing me. I have always been thinking about the computing institute. Now, good things are coming."

If you talk about this, I won’t be sleepy anymore. Chief Engineer Chi immediately became interested.

"I knew Chief Engineer Gao wouldn't forget us. What good news is there?"

Gao Zhendong smiled and said, "I wrote a communication program that is slightly different from the previous one, and it should be quite useful. I have only completed the protocol and sample program parts, and I am going to come here to do some experiments. If there are no problems, I will trouble you with the application interface and shell later."

Chief Engineer Chi was delighted: "Okay, okay, no problem, leave the rest to us. Come quickly, what do you need to prepare? I will prepare it right away and try to start the experiment as soon as you come."

He didn't even ask what it was. Anyway, anything from Mr. Gao was trustworthy.

Gao Zhendong said: "Three computers, two telephone lines, three modems, nothing else is needed for the time being."

Chief Engineer Chi readily agreed: "Okay, I'll get ready right away and wait for you to come over. Are you coming over now?"

Gao Zhendong gave an affirmative answer, then picked up a tape, got on his bike and rushed over there.

What he wanted to test was the email suite, both the server and the client.

During this period, he has found time to complete the writing of the SMTP and POP protocols, and implemented them in the program.

SMTP is responsible for sending mail to the server, and POP is responsible for receiving mail from the server. Without the latter, SMTP can only work when the recipient is online, which obviously cannot achieve the full effect of email.

However, it only implemented the protocol and instructions, and did not package the entire process of sending and receiving emails into the client program.

From a software perspective, a user's simple operation of sending a letter actually involves a series of interactions between the client and the server, and the same is true for receiving letters.

Now Gao Zhendong's client needs to interact with the server's return information and input commands one by one to complete the operations of sending and receiving messages.

Taking the three typical addresses of To:, Cc: and Bcc: as an example, which are often used when sending emails in the future, in fact, there is no such thing in SMTP at all. This thing is in MIME (Multipurpose Internet Mail Extensions) and is integrated into the interface.

For SMTP, the process is simple: send three addresses to the server.

Even SMTP itself cannot send attachments, which is also a MIME extension.

After Gao Zhendong tailored MIME, he implemented a small part of it in his email suite. After all, if the function of sending data attachments is missing, the functionality of email will be greatly lacking.

As for directly inserting pictures and music, which are a bit fancy in the current environment, Gao Zhendong did not consider it and just left space in the cropped MIME.

——Believe in the wisdom of future generations.

This program is not very convenient to use, but he is too lazy to write it. The protocol is fine as long as it can realize the function. As for the rest, there are many people in the computing center, so just throw the interface and the shell to them.

It cannot be said that Gao Zhendong exploited the computing institute's manpower. If anyone says so, Gao Zhendong is not anxious, but the computing institute must be anxious first. What does that mean? You can't stand seeing my computing institute doing well, right? Go away.

Gao Zhendong was still on the road on his bike, and the computing center was already busy. Chief Engineer Chi arranged the staff to prepare the required environment according to his requirements. When Gao Zhendong arrived, he was the only one missing.

Director Li and Chief Engineer Chi were waiting for him in the laboratory.

It’s not that Director Li is too idle, but every time Gao Zhendong comes to do experiments, the results he brings are worth Director Li’s visit, and he also needs to grasp the situation as soon as possible so that he can report the results to his superiors.

Gao Zhendong entered the computing laboratory. He was familiar with the route and had no obstruction. When Li and Chi saw him enter the laboratory, they both came forward to greet him.

"Mr. Gao, congratulations." Director Li congratulated him first. This is a common practice in interpersonal communication. First, it expresses congratulations, and second, it shows that I have not forgotten you and have been paying attention to your news.

Just be careful with your choice of words, as well as the scope, type and taboos of the messages, so that others don't think you are spying on them.

You can congratulate others on their promotion, but don’t bring up things like them winning 8,000 yuan playing mahjong.

After Gao Zhendong thanked him with a smile, he asked Chief Engineer Chi: "Boss Chi, are all the things I want ready?"

Chief Engineer Chi pointed backwards and said, "Over there, the three machines you requested are equipped with three of the most capable operators."

I don’t know whether the operators will need it, but it is better to have it and not use it than not have it when it is needed.

Other comrades on the side also greeted Gao Zhendong enthusiastically, as if they were old acquaintances. Gao Zhendong nodded and handed the tape to a staff member: "Copy the program marked FWQ on one of the machines, which is the server. Copy the program named KHD on the other two machines, which are the clients. Then dial one server and the client, and run both programs."

Gao Zhendong used the Chinese pinyin abbreviation for the program name, but the instructions in the protocol were still in English. Firstly, this thing was to be used externally to expand the country's influence, and secondly, he was too lazy to change it.

The staff of the Operation Institute began to get busy according to Gao Zhendong's request, and the others stopped chatting and watched the progress of the experiment.

More than ten minutes later, everything was ready according to Gao Zhendong's requirements.

Gao Zhendong sat in front of client No. 1 which had already dialed the server and started a series of operations.

A few lines of letters can be vaguely seen on the rapidly flipping screen.

mail FROM:[[email protected]]
rcpt TO:[[email protected]]
There was no such thing as domain names at that time, but Gao Zhendong still used addresses with dots. For some reason, Gao Zhendong used square brackets instead of angle brackets.

The operation process was not too long. After a few minutes, Gao Zhendong cut off the connection between Client No. 1 and the server and stood up.

He gestured to Li and Chi: "Excuse me, both of you. Who is willing to operate on client number two?"

Well, Chief Engineer Gao is still a very good person. Director Li sat down on the operating chair of client No. 2 before Chief Engineer Chi.

If it were any other comrade, Chief Engineer Chi almost wanted to kick that person off the chair, but forget it, this guy is quick.

Decades later, whenever Chief Engineer Chi talked about this scene, he would beat his chest and stamp his feet: "I was too slow, otherwise I would have received the world's first email! That old guy Lao Li got away with it."

No matter who of you receives it, it’s sent by me anyway.

"Director Li, please dial the server first, and then run the KHD program on this client."

Director Li did as he was told. After a handshake, as soon as he entered the KHD program, he saw a message flashing at the bottom of the screen.

"You have a new letter!"

He seemed to realize something and turned to look at Gao Zhendong: "What is this??!!!"

Gao Zhendong did not answer directly, but just smiled and nodded, and handed him a piece of paper: "Director Li, please follow the instructions on this paper."

Chief Engineer Chi, who was standing behind, also realized something and an expression of extreme regret and envy appeared on his face.

Director Li hurriedly took the note and started operating on the computer, even typing a lot of wrong characters.

When Director Li hit the last enter key on the keyboard, the screen flashed and a few lines of words popped up on the screen.

"From: [[email protected]] ”

"Recipient: [[email protected]] ”

"It's like seeing you in person."

The body of the email is very simple. These are the first four words that old-fashioned people often use when writing letters.

These four simple words make everyone more certain that this is trust, trust on the computer and on the Internet.

In that era, letters had a different meaning for the Chinese people.

"Fenghuo lasted for three months, and the family letter was worth ten thousand gold."

"We have no letters since we parted, and we are both old when we meet again."

"A line of letter with a thousand tears, how cold it is to be with you and have nothing to wear?"

"."

It is this method of communication that has been passed down for thousands of years, something that both those who travel far away and their relatives left behind long for, and when it is combined with today's most modern and advanced communication technology, everyone present is caught up in subtle emotions.

It turns out that computers are not only high-brow and high-class, they can also be popular and deeply rooted in people's hearts.

Director Li turned to Gao Zhendong and said, "Mr. Gao, you have really integrated serving the people deeply into your work."

After saying that, he applauded.

Chief Engineer Chi and other staff present followed Director Li in giving warm applause to Gao Zhendong.

Gao Zhendong really didn't expect that these four words would cause such a big reaction from everyone. He was very embarrassed and had to bring up the topic.

"I have only completed the most basic parts of this protocol and procedure. I will trouble you all with the rest."

After the applause subsided, Director Li and Chief Engineer Chi returned to rationality from emotion and began to realize the great significance of this technology.
