Chapter 151: Blue Eagle Has an Accident

Lin Hong only said hello to Lus before, but the other party's reply to him was very long, basically writing down his recent situation clearly, especially about his latest 386 computer and minix operating system, which were written in detail. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

At the same time, Lus also wrote in the letter that writing an operating system is a very large project, and he is currently working on it, but he must first get the basics right. He had a vague idea of being able to slowly expand the system based on minix, gradually improving its functionality, that is, doing the exact opposite of what the minix authors did.

Andrew was a streamlined castration of Unix, resulting in Minix, and Lus wanted to gradually improve Minix and eventually reach the level of Unix. This is obviously a long and complicated process, but Lus has already started to do it, adding a lot of self-written tools to the minix system. The next goal was to write a "terminal emulation program" that would allow his computer to connect to his university's Unix console, so that he could access the console from his home and read the news on it.

At the end of the letter, LUS strongly invited Lin Hong to participate in the project, after all, he did this project alone, sometimes he had a feeling of powerlessness, and when he encountered problems, it was difficult to discuss with anyone, and he almost gave up the project several times. In addition, he also attached the names of the basic books, saying that if Lin Hong is interested, he can go and look at these books. One of these books is Operating Systems: Design and Implementation, which had the greatest impact on LUS.

After Lin Hong finished reading, he immediately replied to the other party.

In the letter, he also told the other party about what he encountered after arriving in the United States, and then said that he was very interested in the project. He decided to join his project as soon as he had the calculator project he had in hand was completed. During this time, he will study the books recommended by Lus to try to keep up with him when the time comes.

When I pressed the send button, the email flew across the sea and traveled to Finland at a wonderful speed of 300,000 kilometers.

Next, Lin Hong began to continue to refine his cracking program.

In the beginning, he cracked the calculator purely out of his own personal interest, wanting to have a simple computer with him. However, the plan never seemed to keep up with the changes, and the formation of the SAM group gave the calculator project a relatively big goal, which was to at least get the students of Latin schools to use the calculators they had cracked.

This goal was set by Matthew, and originally according to his meaning, he hoped that middle school students all over the United States would use such calculators, but Lin Hong and Arthur both felt that this goal was a bit too big and unrealistic, so he revised it and narrowed it down to his Latin school.

Despite this, there are still a lot of students in the entire Latin school, at least a few thousand, and it obviously takes a lot of time and effort to let them crack them one by one.

Today, when testing the relevant parameters of the calculator in the locker, Lin Hong actually thought of this problem.

If you want something to become popular quickly, you must not set too high a threshold, the simpler the better. This is the experience that Lin Hong has seen from various books. For example, if various folk rumors at the end of various dynasties in history want to be quickly spread by people, the version must not be too complicated, it must be simple and easy to remember, and it is best to be accompanied by a song or something, so that it is easier to spread.

Obviously, in order for this project to be successful, it is necessary to reduce the difficulty of cracking, and if the calculator needs to be modified at the hardware level, as Matthew said before, the possibility of rapid popularity is very low, and it is not only a matter of time, effort and money required to retrofit.

Later, Lin Hong thought about it for a while, and felt that the current way of cracking it was also a bit troublesome, and the calculator had to be connected to the computer, and then the program data had to be poured into it, that is, the calculator had to go through the hands of their SAM team before it could be cracked.

So, is it possible to improve this way of cracking it without them having to operate the calculator themselves?

Lin Hong found out the information mailed to him by Texas Instruments before, re-studied it, and combined with his own cracked code, he finally found a solution.

The process is actually similar to the previous one, he improved his cracker and disguised it as a ti-baisc program, so that the original system would think that it was an executable program that met its operating standards and could be run.

But after starting, it was actually a cracked program written by Lin Hong.

Considering that the actual storage space of the calculator is relatively small, Lin Hong streamlined the program and finally compressed it to only one ordinary 5KB size, even if the calculator comes with infrared protocol for communication, it can be transmitted in less than a second.

Of course, whether the final written program can work or not, Lin Hong still has to be tested. But now that he doesn't have a computer that hasn't been cracked, it's a bit of a trick.

He looked at the time, it was almost eight o'clock, and it was completely dark.

So, Lin Hong walked out of the room and knocked on Arthur's door.

Arthur is improving on the previous Tetris game at the moment, reinventing it to allow for two-player online play, and introducing a competitive mechanic to increase playability. And in terms of playability, Tetris is still better, this is a classic game that has become popular all over the world.

Lin Hong told Arthur his thoughts. Arthur certainly knows the significance of this hack, and in this way, the chances of their SAM group succeeding can be greatly improved.

"If it can be realized, it will be great!" Arthur was pleasantly surprised, "Let's go to the city and buy a new calculator right away!" ”

"Buy a new one?" Lin Hong hesitated, "A calculator costs a hundred dollars, is it just to buy it for testing?" After the test, who will use it? ”

"That's a real problem." Arthur scratched his head, "Perhaps, we can borrow one from the other classmates, anyway, we have to help them crack it sooner or later, well, that's it!" Let me think about who can borrow ......"

Thinking about it, it's really frustrating that Arthur can't find a classmate who can borrow a calculator except for Matthew.

In the end, Lin Hong said: "Why don't you borrow it from Si Qian, I know her phone number and address, and she stays at Joanna's house." ”

As soon as he heard Joanna, Arthur was a little excited: "Shall we go to Joanna's house now?" Shall I wear the new dress I just bought? ”

"What are you doing in a dress?" Lin Hong was surprised.

"Let her see if it matches the color of her dress?"

"Uh...... I don't think it's okay, even if it doesn't match, I don't have time to buy new dresses. ”

"Yes, just do as you say."

Before they went, they called the other side and explained why.

Lin Hong and Arthur drove over on motorcycles, without alarming Vina and Orlando, this mountain bike was later accompanied to him by his uncle, and the brand was exactly the same as before.

The two of them stopped at a distance from Joanna's house, walked over and borrowed two calculators without alerting each other's parents. Although Joanna tried to invite them into the house to sit down, the two otaku were too willing, but they just excused themselves because it was too late and had something to do when they got home, so they hurriedly rode away on their motorcycles.

With these two calculators, the rest of the work went smoothly, and after a few debuggings, the crack was successful.

In the process of debugging, Lin Hong suddenly had an inspiration, and finally wrote a cracked restore program, running this program can restore the cracked calculator to the state before it was cracked.

Arthur sighed after testing it a few times, he knew that he wouldn't have to run hard, but he was just talking, and it could be seen that after meeting Joanna before, he was in a very happy mood all night.

In the end, Arthur got the Tetris online version done, and then tested the cracking and transmission functions, and finally made sure that there were no problems, and then went to bed with peace of mind.

Lin Hong, on the other hand, continued to surf the Internet.

Since Tulip BBS is the first BBS he has been on, he has a little affection for this BBS, and every time he will go to this BBS first to take a look at the latest posts, he is most concerned about two sections, one is the news section, and the other is the user work sharing. Of course, there are several other sections that sometimes go for a stroll and see what's interesting.

After reading Tulip BBS, he logged in to some other BBS he knew to check it out. The addresses of these BBSs were all he had seen from other people's posts, otherwise he really didn't know how to find them.

In Lin Hong's view, the Internet is like an ocean, and these websites are islands in the ocean, although these islands can be accessed by boat, but if you don't know the specific coordinates of these islands, then these websites are basically unpopular.

Due to the accumulation of experience, the old bird remembers the domain name or IP address of these websites very clearly, and can visit it directly and purposefully every time, but for the rookie, it obviously takes a certain amount of time and effort to discover these islands.

"If someone publishes such a post and lists some famous BBS and websites in it, I believe it can provide convenience to many people, whether they are rookies or veterans." Lin Hong conceived such a post in his mind, "There is not much content, each site only needs a name and a corresponding hyperlink." But there are so many sites around the world that if you want to list them all, one post doesn't seem like enough...... For this post to be seen by more people, it's best to have a very simple URL...... Hmm, maybe it's better to make a bootstrap like this, which doesn't require other complicated features......"

Lin Hong was browsing through the posts while conceiving such a thing in his mind.

When he logged into another BBS called "Hacker News", he noticed that there was a word that was repeatedly mentioned - the Blue Eagle Hacker Group.

"What happened to the Blue Eagle Hacking Group?"

"According to reliable information, the leader of the Blue Eagle was arrested by the FBI, is it true?"

"Blue Eagle's internal forum is no longer accessible!"

"Big news, this afternoon, the FBI launched an attack on the Blue Eagle BBS......"

……

"Blue Eagle?" Lin Hong was shocked in his heart, "Isn't this Arthur's hacker organization?" ”
