Chapter 183 Cracking Tutorial

Since it was the weekend, although Vina had to work overtime, she also came back early, and by the time Lin Hong and Arthur returned home, she was already preparing dinner at home. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

At the end of her meal, Vina asked about the New York bank robbery, which she had seen on the TV news, and if Arthur hadn't called her this morning to tell her that she was safe, she would have been in a hurry. Of course, she didn't know that her precious son had been through the whole robbery himself, and Arthur only said that he was watching from the sidelines.

However, when Arthur explained the whole process of the robbery to her later, he was a little too detailed, if it wasn't for Lin Hong's secret reminder in time, she would almost be in a goof.

After dinner, Lin Hong and Vena chatted in the living room for a while, and then returned to their room.

At this time, the Chinese time should be Sunday morning, Lin Hong thought about it for a while, and decided to call his mother, after all, he hadn't been in touch with home for a long time.

When he picked up the phone, he remembered what Kevin had taught him about the phone today, so he wanted to try dialing using a fork spring.

At that time, he seemed to be very easy when he watched Kevin shoot, and he succeeded in a few clicks, but when it was his turn to practice, he found that this was not a simple thing, the first three codes in China were 086, and 0 represented ten pulses, so he needed to shoot 10 times, but he encountered difficulties here, and the time between each time was not accurate, resulting in the failure of dialing every time.

However, after experimentation, Lin Hong slowly mastered the trick, so the interval between each slap was finally fixed at more than 40 milliseconds, but less than 100 milliseconds, and finally dialed his mother's phone.

Feng Wan is still sleeping lazily at the moment, and finally has a weekend, and she can finally have a beauty sleep, so she naturally doesn't want to let it go. But receiving a call from her son swept away all her sleepiness, and she was very happy. Before this, she usually called Lin Hong, and Lin Hong rarely took the initiative to call back, and this time it was a big surprise for her.

The whole call process was the same as before, Feng Wan was asking, and Lin Hong was answering. Lin Hong mainly talked about going to Mu Sitong's side in the past two days, of course, the robbery in the bank was also concealed in good faith, which he had already been angry with Mu Sitong, asking her not to tell her mother about it, so that the family would not have to worry about it.

After hanging up the phone, Lin Hong took a moment to crack the calculator he bought from the store last time, and it was the same, only slightly changed the source code and completed it successfully. However, other brands of calculators have not been cracked, but only cracked several other versions of Texas Instruments, after all, the hardware structure and system are different, and he has no information in this area for the time being, so he can't start.

Next, Lin Hong began to write the cracking tutorial and the cracking principle, although the steps involved in this are relatively simple, but this basic instruction manual is essential. When it was twelve o'clock, he would post the content so that everyone could see and download it in time.

The computer he was using now was much more powerful than the Apple-II before him, so it was easy to use. And, now he is no longer using the "two-finger Zen" for typing, but under Matthew's strong recommendation, he has practiced a scientific typing method, and has mastered the way of fast blind typing in just one day, at the beginning he still felt unaccustomed, but after getting started, he had to admit that this kind of typing method that has undergone the test of history does have its science, and his typing speed has been greatly improved.

Aside from the design of the key layout, typing training is actually similar to his usual martial arts, which is to practice some fixed movements into his own instinctive reactions, or to establish a special reflex belonging to typing in the brain, no longer need to go through complex thinking, but immediately react after putting the hand up, just as we usually talk while doing other things.

Maybe Lin Hong himself didn't realize that his way of thinking about problems has gradually begun to become more mature and rational, and when he sees a thing or phenomenon, he often sees the laws and essence contained in it through the phenomenon, and he can't help but enter the "God's perspective" and look down on it from a certain height as a third party.

When it was almost twelve o'clock, Arthur knocked on Lin Hong's door.

"Stone, it's almost time, come to my room!"

"Okay."

This is what they have said a long time ago, to witness the exciting moment of the launch of the "SAM Association" BBS together.

When Lin Hong came to Arthur's room, he saw him chatting online with Matthew and Pissen. He uses an online chat software based on the UDP protocol, which can realize multi-party chat on a point-to-point WAN, but this software is a special software in Apple's system, and there is no such similar software in the DOS system.

Lin Hong pondered in his heart whether to develop one by himself, so that it would be much more convenient for everyone to communicate with each other, otherwise because of his different operating systems, it would be difficult for him to communicate with them alone.

In the last dozen seconds, Matthew's countdown number appeared in the chat window.

“10”

“9”

……

“2”

“1”

“start!”

Arthur immediately switched out, started the network dial-up, logged in to the network, and then opened the tel software, entered the domain name of the "SAM Association" BBS, and the welcome message after the successful login of the "SAM Association" immediately appeared in the interface.

"Welcome to the SAM Technology Frontier Association!"

Underneath this large line, there is a short text describing the main introduction of the SAM Association, as well as a description of the calculator cracking of the key work of the TI-8X series.

These texts, all from Matthew's head, are more general, and of course, slightly exaggerated. In his words, he is describing the state of the SAM Association after the future, and it is not an inaccurate description.

Below are two simple section names that prompt visitors to choose to enter.

Although both Arthur and Lin Hong are no strangers to such an interface, but this time they feel completely different, after all, this is the BBS they participated in setting up, and they have a special affection for it.

So next, the four people of the SAM Association began the process of enriching the content of the entire BBS.

They said before, don't simply paste and copy the content on other BBS, you must have your own things, and you must be useful to users to be able to retain them.

Of course, because their current knowledge is concentrated in the field of calculators, as far as they know, there seems to be no such professional site in the industry, and the cracking of calculators itself started from the SAM group, so they are considered the founding patriarchs of this field, and they have a natural appeal, but they are not very worried about others not recognizing.

Lin Hong returned to the room and uploaded the content of the instruction document he had just written to BBS, and then uploaded several cracked files used to crack the calculator to the association's public FTP.

At this time, BBS was still relatively simple, unlike later generations, where you could upload attachments directly on BBS. During this period, file sharing and exchange were carried out on the network, and FTP was generally used for file sharing.

The three letters FTP itself are short for "File Transfer Protocol", which is a protocol built on top of the TCPIP protocol and is specifically designed for file transfer. FTP has its own server and client, which is very similar to a web server, and users can use special FTP software to connect to the server and download files from it.

Unlike web services, which run on port 80, FTP services typically run on ports 20 and 21. Of course, there are also some maverick websites or FTP servers that deliberately change the default ports of these common services for security reasons or other reasons, so that others don't have to scratch their heads at all, and if they want to invade, they have to spend a lot of trouble finding ports.

Next, Lin Hong continued to publish several posts in the "Hardware" and "Software" sections, all of which were some of the details he learned in the process of cracking the calculator. The most informative of these is a post titled "Teach You How to Hack a Calculator". In this post, Lin Hong described in detail the whole process from the beginning of getting the calculator and then starting to crack it step by step, not only the technical details, but also the cracking ideas, what to think when encountering obstacles? What would you think?

It can be said that this is a fairly detailed tutorial on how Lin Hong wrote his article, and the way he wrote his article was also like this in the Red Skin Nine Astronomy Atlas that Wozniak learned.

There is a big difference between the online world and the real world, and many people will show completely different personalities in these two worlds, and Lin Hong is no exception.

The network ID he uses is none other than "hellc".

The reason why he took the time to write such a tutorial was nothing more than that he wanted to steal electricity.

Before, cracking calculators was purely out of interest, but now, with so many different brands of calculators to crack, this is no longer an interest, but a coolie. He didn't want to spend too much time on this, after all, the process of cracking was basically the same, and he had a lot of other things he wanted to do, so he wanted to gather the wisdom of the masses, write out the methods and principles, and then call on everyone to hack other types of calculators by themselves, and then share them, so that these calculators can be cracked in a short time?

Although not all calculators can be cracked, the process must be explored and tested, and it will take time and experience. If Lin Hong had to do it alone, it would be too terrifying. Lin Hong agreed to build an official BBS before, which was in this consideration.

The wisdom of the masses is infinite, and Lin Hong has long had this clear understanding.
