More than two months have passed in the blink of an eye, and Hong Kong has entered the hottest time of the year, and people who are exposed to the sun are afraid to go outside.

I have been working with a wet towel for a long time, and I am really unhappy in my heart, and I miss the days when there is air conditioning. But the mood is okay, because they have finally overcome the difficulties of the graphics processing system after a lot of hard work.

Of course, this also has the credit of others, that is, Su Jian, a Chinese professor who flew from the United States.

Professor Su works at Stanford University and is a good friend of Dr. Yu, and he can't resist Dr. Yu's affection, and he flies across the ocean to Hong Kong for two days a week to take classes, which is very hard.

Although he knew for a long time that Professor Su also asked for money for classes, his professionalism was also worthy of respect. Therefore, he was very polite to this senior for a long time, and specially communicated with him.

Professor Su is a discerning elder who came here with the intention of spreading culture. To be honest, on his terms, he doesn't need to be paid for this job at all, it's tiring and hard.

But Dr. Yu asked him to go out of the mountain just to sow seeds on the mainland. Professor Su felt that there was no excuse for this reason, so he gladly accepted it.

When he first came to Hong Kong, Professor So was very worried about the teaching conditions and the quality of the students, and he was not relieved until he saw it with his own eyes.

The students are very studious, diligent in their studies, and have been led through the door for a long time, which has saved Professor Su a lot of effort and allowed him to get straight to the topic.

Unlike Cao's style, Professor Su does not teach the operation and application of various software and the learning of various computer languages, but focuses on programming and algorithms.

This made Chang Chang very strange, and he discussed it with Professor Su in private.

Professor Su did not despise him for his long youth, and answered his questions very warmly and in detail. Professor Su believes that as a programmer or an ordinary student, the first task is not to master as many software as possible and how many tools to use, these are just the details.

What we should really pay attention to is the program itself, the problem and the algorithm, and the cultivation of students' problem-solving ability, especially the ability to solve mathematical problems, Professor Su said.

When Cao Changchang first heard this, it was like an initiation, and he thought it was true. He himself has felt it for a long time, but he can't say it.

When I was dreaming, as a generation of students who were poisoned by the special education system, I was deeply touched by this for a long time.

When I was young, my family was poor, and I barely studied for college, and I didn't know that there was such a thing as a computer in the world until my sophomore year of high school. Out of interest, at the moment of intense study in the third year of high school, I spent more than ten days of living expenses to buy a bound book of computer newspapers, and used this thing as extracurricular reading material every day.

At that time, his biggest hobby was to buy a provincial newspaper on the weekend (there is no computer newspaper for sale in a small county), gnawing on the quotation of accessories on the computer page line by line, and then building a machine in his mind (no silver!). Until the end of high school, I haven't touched the so-called computer for a long time, and I always enviously watch the rich Xiaobai use the Chinese learning machine to play games.

Later, he was admitted to the computer department of the university for a long time, and with his pure paper understanding and reasonable imagination, he was able to blow the sea with those classmates who were full of windows and VC, but there was no concept of physical objects at all.

Over time, the students also knew that there was a person in the department who could talk big, and he couldn't operate a computer at all, and he could still be there in the clouds.

Of course, all the knowledge about computers for a long time comes from that set of computer newspaper bindings, and it is certainly not as good as those children who grow up on computers. But he has a good foundation, and after a few computer operations, as soon as the theory in his mind is confirmed, the long-term level will immediately grow and improve by leaps and bounds.

At that time, of course, the courses in the university did not talk about new things such as VC programming, but the teachers who taught pascal always mentioned in the class, saying that the school was really backward, saying that c, c++ were used outside, and some even used VC, and we were still trapped in the backward pascal, and you should also use VC in the future, so learn by yourself!

At that time, I had admired the teacher for a long time, and I was deeply moved by his far-sightedness and thoughtful care for students. So together with all my classmates, I spent N months of food money to buy the "Windows Programming Encyclopedia" and gnawed wildly, and I didn't listen to the teacher's class at all.

The conversation between the students was also full of running trains, what "the Hungarian nomenclature is really a great invention", what "how advanced is the x86 storage technology", etc., etc., this is the situation of Cao Changjiu's department at that time.

It wasn't until he came into contact with Unix for a long time that he wavered. What a perfect operating system this is, refined and beautiful language, mature, stable and efficient system, and in the long run, it is almost an artifact.

It's a pleasure to work and code in Unix, and you don't have to worry about problems that aren't a problem in the first place. For example, the memory leak problem that is common in programs under Windows has not been encountered for a long time, and there is no such concept in UNIX.

Cao felt fooled for a long time, and the Wintel Alliance created a closed environment for people to feel that their technology was advanced.

Later, after a long period of contact, I also learned some situations, such as why Microsoft makes money, why the x86 architecture has so many and complex access instructions, and so on, all of which are based on the long-term familiarity with Unix.

What is deep hatred, I have understood for a long time, it is a feeling similar to the feeling of Neo from the matrix back to the real world.

Later, I came into contact with Linux for a long time, successfully found the organization, and became a member of the open source organization.

For a long time, most of the world's scientists and engineers used UNIX as their computer tool. Just because it's simple, reliable, stable, powerful, and fun.

High school teachers at MIT, Stanford, Bell Labs, and even small European countries are dismissive of Microsoft, which they see as a monster that relies on commercial propaganda and monopolies.

How did this monster come about? Listen to me slowly, if you want to use a PC, you must have an operating system, and you can buy a set of 98 for more than 100 dollars.

In order for your operating system to be up-to-date, the monster will also tinker with you, well, and it will be more than a hundred times each upgrade (I don't understand why the tattered can be taken out and sold, and the patch will cost money).

98 is like this, it's just an ordinary user version, do you want to do something serious? buy NT, it's not expensive, it's just several times more expensive than plague 98.

Of course, the high-tech system has a score level, 5 user version, 10 user version...... The more detailed the distribution, the better, and you have to pay proportional to the number of users.

The system has it, can it work?8 lines, damn Microsoft doesn't even provide a compression program, buy !winzip for only 29 US dollars.

No, now the society is so chaotic, the virus is raging, and the data is ruined and can't be recovered, so you have to pretend to be a Norton, buy it!70 US dollars.

What about hackers? It is said that these guys are very good at stealing, and the company's trade secrets cannot be leaked, so add a Norton firewall for only $100.

It is said that the disk under windows will slow down after a long time, and the system is always optimized for ordinary settings, NortonSystemWorks can help you do these tasks, and the dollar will attract $100.
