In the original time and space Internet era, all kinds of forums can be traced back to the current BBS in terms of function and technology, and it can even form an independent front-end application package product, which can be distributed to users of similar scale although the purpose is different, and most of the differentiated needs can be solved in a centralized configuration file.

The PBBS that Zheru is still testing has reached such a point, and Tang Huan also recommended this system to the White House press secretary James who came to the acupuncture department of Treasure Hospital for physical therapy? Brady.

Because in the Reagan assassination a few months ago, James? Brady was paralyzed by a bullet in the head, so he is now retained as White House press secretary, but the actual work is done by the deputy.

From a glamorous presidential mouthpiece to a nominal ornament, James? Brady's psychological gap is not difficult to imagine.

Recently, Tang Huan, who has been a cat in Silicon Valley, specifically put James? Brady was brought to the Zheru R&D Center in Cupertino from San Francisco to see PBBS in action.

Limited by the current level of network and hardware development, the functions of PBBS are naturally much more unpretentious, such as only supporting text, and even if each post can cover 10,000 floors, its resource overhead is not worth the loss.

Of course, there are no workarounds, such as arranging the sympathy with ASCII code, creating a theme for the post, and so on.

So, James? The PBBS performance that Brady saw was very exciting, and the "average" comment was only Tang Huan, who knew how far the network would develop in the future. to be qualified to speak.

Although now PBBS is mainly for computer technology. But precisely because of this. It is even more necessary to adjust the boring atmosphere, and its social page is extremely lively.

Unlike those technology enthusiasts, as well as due to various external factors to promote the group to become the pioneer of the BBS platform, PBBS as soon as it debuted, it is known for its professionalism, in addition to the use of mature and advanced supporting hardware and software, but also very wealthy to rent a number of communication lines, this alone makes other BBS inferior.

Arguably. PBBS has become an important meeting center for people attracted by the emerging BBS culture.

Naturally, the famous feature of the virtual world is reflected, that is, it is impossible to tell whether it is a person or a dog typing on the keyboard on the other end of the terminal, and everyone has no scruples about what they say.

Just like the recent Chinese billionaire Tang Huan was caught in a public opinion turmoil, he was tried by everyone to do his best, whether it is to scold the nouveau riche who deserve it, or sympathize with the minorities who are always prone to encounter the invisible ceiling, they are all targeted, after all, the cost of the Internet is still very expensive, and cherishing the ID with considerable gold content is the instinctive consensus in the initial stage of BBS development.

Among them, there are many so-called people of insight. Supporting Tang Huan to deal with this crisis of public opinion, which is a spoof. often attracts blockbuster discussions, and even has a violent temper and scolds Tang Huan for being stupid, which is one of the characteristics of non-professional grassroots media communication shown by BBS.

James? After graduating from the University of Illinois in 1962 with a bachelor's degree in political science, Brady began serving in the government and has been an assistant to senior ministers since 1973.

In other words, the boss moved his mouth and his subordinates ran and broke their legs to describe him.

Because of these practical work experiences, James? Brady didn't need Tang Huan to point it out too bluntly, but he discovered the value of BBS - a new mass media that he could operate behind the scenes, although he could not show himself in front of the public as he used to.

"Is this product ready for sale?" James? Brady asked, with a blazing eye, "Perhaps, the White House press office is suitable for this system." ”

"It's still being tested, but it's already very useful." Tang Huan smiled slightly, "As the first customer, I can give away this system, but the hardware needs to be paid." ”

"Then it's decided." James? Brady pointed to the PBBS-specific Zheru mark on the monitor, "How long will it take for this information to be changed to the words corresponding to the White House." ”

"This product uses our original centralized configuration, and it is even too late to adjust it after it is sent to the White House." Tang Huan replied confidently.

James, who is in a hurry to prove that he still has "use value" and not a white-collar pension? Brady, despite his wife's objections, immediately returned to Washington and asked Reagan for instructions, saying that he had discovered a new high-tech tool for communicating public sentiment, and if the White House press office adopted this tool, it would certainly have good results.

Originally, during his eight-year presidency, Reagan had kept the sad subordinate of the city gate fire and the pond fish hanging the title of White House press secretary, no matter what the purpose, there may not be a trace of guilt in it.

Whether this speculation is reliable or not, James? Brady's suggestion, Reagan immediately agreed, and left the other party to take full responsibility.

So while CNN's X-Files repeatedly mentions BBS, it has quietly walked into the White House.

and a wider range of media personnel, connected to the currently most recommended PBBS via personal computers and modems, have fallen a little behind.

However, their accident is also not small, it turns out that the virtual space can also be so lively.

And the clues claimed by CNN can indeed be found here, such as the public information on the daily operation of the Shennong Foundation.

Many of them were dazzled and abducted into the MUD game world like lost lambs.

Soon, the directors of various media jumped to their feet and scolded, whether there was something wrong with AT&T's system, why did the number on the bill suddenly become so big, it seems that you are right to split up.

No, the black heart of this company must be revealed to the public.

As a result, unconsciously, the criticism of Tang Huan in the media was replaced by discussions and even popularity about the various products of the company under his name. And the lawsuit between Tang Huan and the San Francisco Observer. It is also mentioned from time to time. What stage has it reached?

……

Tang Huan has already left the fearless stage of being barefoot and not afraid to wear shoes. In his current status, he is like porcelain, and he must know how to protect himself in order to be the best strategy.

For those attacks that have nothing to do, it is not okay to go to the front line shirtless, nor can it be rash to act rashly to leave trouble, in short, there are many constraints, and the best way to resolve the problem is to make it invisible.

Not so high-end, not enough to convince allies and fear opponents.

With the help of CNN, which is eager to fight its way through the media field. After slapping the Washington Post hard and smashing the reports of the Washington Post and the San Francisco Observer, Tang Huan decided to bring down the San Francisco Observer once and for all.

This grievance is so obvious that there is no need to hide it, just resort directly to the law.

The husband was angry, and the blood was splashed in five steps, not to mention the dignified capitalists, the billionaires have more Chinese prefixes, which does not mean that anyone can provoke them.

It is also a good time to consolidate the public opinion support of the base camp of San Francisco, otherwise it will be a newspaper on its own turf. Kicking your nose and scolding in your face is really good to say.

But Regis? McKenna presented Tang Huan with a problem. "Since you don't bother to open your mouth to respond to questions about your integrity, it's time to take action and fight back. And the point of academic fraud is the most critical, you might as well continue to study for a doctorate and shut everyone up. ”

Hearing this suggestion, Tang Huan grinned bitterly at the time, Gaine juggling work and study, it was really a hard thing to make himself retreat, and he insisted on his master's degree completely to explain to his aunt.

What's more, for Tang Huan, the higher academic title is just an embellishment, and his achievements no longer need to be proved by this.

But Regis? McKenna analyzed it well, listened to the advice of others, and hired a public relations consultant himself, isn't it just to let him check and fill in the gaps.

For convenience, Tang Huan directly chose Stanford University, which is located in the heart of Silicon Valley.

Zheru has a special advisory body to recruit well-known computer experts and scholars, so he knows a lot about the professors at various universities.

Regis? McKenna's suggestion was to find a mentor of non-Chinese descent, and as a result, he picked and chose Donald Ervin Knuth - Donald? Ervin? Knus.

Before visiting China in 1977, he took a Chinese name called Gartner, and won the Turing Award in 1974.

Considering his academic status and his understanding of the cultural differences between the East and the West, Tang felt that Gartner was indeed a good choice, so he decided on it.

The next steps to find a letter of recommendation and so on are not a problem for Tang Huan at all, and they are all done after a flow operation.

Gartner is an interesting man, a hacker who has two major elements for him: a tireless pursuit of technology and an obsession with music.

Gartner had already dealt with Tang Huan before, and clearly said that he liked WordEasy, a text processing software, because it made it much easier for him to write the book "TheArtofComputerProgramming" - "The Art of Computer Programming".

In addition, Gartner also became interested in Tang Huan's desktop publishing system, and even began to develop a font design system called Metafont.

It can be said that there is a like-minded taste between Gartner and Tang Huan, so this master-apprentice relationship was established very smoothly and quickly, and Tang Huan officially became a doctoral student under Gartner.

Immediately afterwards, Gartner assigned Tang Huan a task - an opening lecture to answer his master's thesis on operating systems for interested people.

From the level of superficial sensory cognition, the operating system is also a file that is called into memory by the CPU from the disk, but it is more special because it is at the bottom and controls all hardware resources.

Whether an operating system is advanced or not depends on many aspects, such as the way memory is used, especially in a multitasking environment, if it performs well, it makes full use of hardware resources steadily, and if it performs poorly, it causes a system crash due to improper resource allocation.

However, it is often difficult to balance the robustness and efficiency of the system, and it is necessary to find a reasonable balance of compromise.

This is like a busy road, if a car is unruly and jammed, it may not only not be able to speed up on its own, but also cause traffic jams.

If you put a fence between the lanes and separate the lanes from each other, you can let all the cars drive honestly in their own lanes, and cannot interfere with the operation of other lanes, even if there is an accident, the harm is only limited to this lane, and will not cause the entire road to be paralyzed.

However, if the vehicle really needs to change lanes, it can only wait for the next intersection, which undoubtedly increases the time cost and reduces the efficiency.

For example, Microsoft's MS-DOS, its own memory space and the memory space of the application are not isolated from each other, if the application is not designed to be standardized, something goes wrong and crashes, then MS-DOS will also be affected, and the whole system will crash.

Windows provides this isolation, which greatly reduces the likelihood of crashes.

In addition to this choice of isolation between the operating system and the application, there is a similar phenomenon within the operating system, after all, the operating system will only provide more and more functions, and modular design is a natural choice.

However, if the isolation mechanism inside the operating system is not used properly, it is very easy to reduce the execution efficiency of the system.

Therefore, the modularization of the operating system is also a topic worthy of careful discussion, so three concepts have emerged around the operating system kernel: Microkernel, Monolithickernel, and Hybridkernel.

Tang Huan's master's thesis explores such topics, especially his practical experience with FreeDOS, the operating system used by Fangyuan computers and Xiaobawang game consoles, and the operating system Vientiane/AllOS, which is being developed and tested for Yi Peng/Holder servers/workstations.

One of the more successful general-purpose high-end operating systems is Bell Labs' UNIX, which provides some server-only features that have become the focus of research.

Tang Huan's exposition in the paper made the eyes of those who paid attention to this field shine, but many readers felt that he had reservations, so he had the task of giving a speech assigned by Gartner.

When Tang Huan came to the scene, he found that many people had a relationship with him, but a few of them made him smile playfully, "I said why did you urge me so enthusiastically, it turned out that I was waiting to absorb the experience so that I could start a company." (To be continued......)
