Chapter 150 LUS? LINUS!

Vina was very happy that her son had found a dance partner. In particular, the other party was still Joanna, so she had a very rich dinner in the evening and even opened champagne to celebrate. Of course, only she and Orlando, Arthur and Lin Hong could only drink. They haven't arrived yet. Enough age to drink.

Although Lin Hong and Arthur really want to taste the taste of alcohol, this behavior will obviously not be recognized by Vina and Orlando, because in the United States, minors under the age of 18 are prohibited from quoting alcoholic beverages, which is illegal. Not only are teenagers breaking the law, but those who provide them with alcoholic beverages should also be held accountable.

Is it illegal to drink in your own home? Lin Hong was a little surprised by this. He once secretly drank Master's liquor with Sun Wu.

Arthur explained the law in this regard to Lin Hong, and also told him a joke in this regard.

It is said that a young man robbed the store and took all the money from the cash register. When he finally left, he took a bottle of wine from the shelf. At this time, the boss who had been staying in the corner and was immediately anxious. He said that I had no problem with taking the money away, but the store absolutely did not sell tobacco and The robber directly took out the social security card and showed it to the boss to prove that he was 18 years old. Later, the police arrested the robbers based on this clue.

Although it is just a joke, it can also be seen from this that the American people attach great importance to this law. If a minor violates this law, he is likely to be punished by community labor or legal study related to drinking.

After dinner, Lin Hong chatted with Vina and others for a while, and then returned to his room.

Turn on and dial to connect to the network.

"What? Do you have a new email?

Lin Hong's eyes suddenly lit up, and he remembered that he had sent an email to Lus yesterday.

He immediately opened it and saw that it was indeed a reply from LUS.

"Hello, old friend, I'm glad to hear from you. It seems that you are doing well in the United States. You connected to the Internet so soon and sent me the first email. You know, a month ago, you didn't even know what EMAIL was..."

LINUS is currently a sophomore at the University of Helsinki in Finland.

Before the year, he could no longer stand the aging of INCLAIN QL (SCQL) and the inability of its operating system to program freely, so he made an important decision to sell it and gradually save money to buy a new computer.

But this SCQL computer is too niche. Whether in high school or college, he has never seen anyone use this kind of machine. People use those Pс machines more, but for him who has already played 68020, it is really a PC with the same function as a toy. I can't get any interest.

This situation continued until the end of last year. He found that with the popularity of 386 CPU chips, the Pс machine can do everything that can be done on the 68020, and more importantly, the PC is cheaper than the 68020.

Of course, there is another important reason why he wants to change to a new machine, that is, in this year's computer course, there is a course called "U Lin's System". Although this course has not yet started, he is looking forward to it. To this end, he specially went to the bookstore in advance to buy a textbook that matched it, called Operating System Design and Execution.

LINUS spent about a month reading through the large part of this 719 pages. In this book, the author Andrew mainly introduces an operating system called "MINIX", which is specially written by him for classes. A simplified version of UNIX, which is very small and many functions have been castrated, but it is indeed an independent operating system that can run successfully in computers.

This book has a great influence on LINUS. Everyone has a book that affects his life. For LINUS, this book is Operating System Design and Execution.

Through this book, after LINUS learned the concept behind UNIX and what the powerful, sharp and beautiful operating system can do, he decided to buy a machine to operate NUIX. Of course, the full version of NUIX is not available. He intends to run MINIX on the machine. He can mail-order the version directly to Professor Andrew, who is far away in the Netherlands.

The SCQL computer in LINUS's hands can still run normally. He felt that it was a little wasteful to put it out directly in the warehouse, so he wanted to sell it and at least make some money for his next computer. The problem is that his computer is so niche that no one is interested in his computer at all. Later, he had to spend some money to advertise in a computer magazine.

After waiting for a while, a man named Joko finally rode a confident car to him, because he also had an SCQL computer. Originally, he thought he was the only person in Finland who used this brand of computer, so after seeing this advertisement, he came. On the one hand, it is to make friends, and on the other hand, I also want to buy some accessories from LINUS. After all, LINUS' accessories are relatively good, and he worked hard to mail them from the UK.

LINUS and Joko became friends, and his accessories were almost half sold and half given to Joko. His deposit plan failed to be realized before the New Year, because a 386 PC is too expensive. Although the price has been greatly reduced, it also requires at least 18,000 Finnish marks, which is converted into US dollars, about 3,500 US dollars. This is a huge sum of money for him.

At this time, the "UNIX operating system..." course has started. Fortunately, the University of Helsinki imported a micro-concave X host from abroad last fall. The operating system used is ULTIX, and the ULTNIX ratio is one of many UNIX versions. This is a multi-user operating system that allows many people to use the terminal and log in to the host at the same time, and the user does not feel that others are also using the computer at the same time. In the user's view, he seems to be operating an independent computer.

The terminal is not a computer, but a device specially produced for a multi-user host. This kind of device usually only has a display and keyboard, that is, an output device and an input device. It is connected to the host through a cable and operates the host through remote login. All operations and operations are far away. It is carried out on the host.

At the beginning, LINUS was to learn UNIX on the terminal, but due to the limited number of places, only 16 terminals can be connected at the same time at a time, and there are 32 students who have taken this course, so the teacher has to divide the students into two batches, one batches use machines during the day. The other batch is used at night.

This is obviously very inconvenient. At this time, LINU dreams of having his own PC and running UNIX on this machine, so that he can operate it freely at any time.

The New Year's bells rang. After Christmas, LINU spent his twenty-first birthday. At this time, he finally made up his mind to buy his third computer anyway.

At this time, he only has 6,000 Finnish marks in his hand, which is all the funds he can raise after spending the two important festivals of "Christmas" and "Birthday". Although it is not enough to branch the computer with a large Finnish marks of 18,000, there is a way for him to get this one. Machine, that's installment payment. He can pay one-third of the amount in advance, and the remaining amount can be paid within three years.

So, LINUS came to the computer store with a huge amount of Finnish marks of 6,000 and ordered a comparison machine from the store owner. There was no brand. He didn't care as long as it was 386. The memory should be at least 4M and the CPU was at least 33MHZ. LINUS provided his own needs. The shopkeeper, and then the shopkeeper asked him to come and pick up the goods in three days, and then they will assemble the computer.

After three long days, LINUS finally moved his third computer back with his father. The gray shell is not good-looking, miscellaneous, with a 14-inch display.

The standard operating system of this computer is DOS developed by Microsoft, but LINUS doesn't like it. He wants to install MINIX on it so that he can practice some of the knowledge he has learned about the operating system.

So he picked up the phone and spent a total of $169 to order a MINIX, and the system will arrive in Finland in a month.

He felt very helpless about it, but there was nothing he could do. Only in this way could he get a copy of MINIX.

So, after a long month of waiting, he finally received the goods. He used a total of 16 floppy disks to finally install the operating system into his 386 computer. NEXT, IT TOOK HIM SEVERAL Days TO MATE THE MINIX. THE RESULT WAS THAT HE WAS A LITTLE DISAPPOINTED, BECAUSE THE OPERATING SYSTEM WAS TOO SIMPLE. THE AUTHOR REMOVED MOST OF THE FUNCTIONS OF UNIX, LEAVING ONLY A FEW SIMPLE FUNCTIONS FOR DEMONSTRATION, SUCH AS A SIMPLE FILE. System and memory management mechanism.

So, LINUS began to transform MINIX again. To his satisfaction, the computer is completely controlled by him, and he even has a copy of the source code of the operating system. If he wants to, he can clearly know all the operating mechanisms in it. As a result, he gradually began to port the software he had written before from the previous computer to this machine.

It took him about a month to finally make him satisfied with his MINIX and able to meet some of his daily operations. But he knows that this is far from enough. Compared with UNIX, the MINIX in his hand is more like a toy. Usually, he still uses the school's terminal for UNIX learning and online surfing.

So, he started another project to write a "terminal simulation software" for his MINIX, using software to simulate the terminal, so that he can also connect to the college host at home.

At this time, LINUS received an email from his ham friend STONE.
