Thanks to p2p download software such as BT (bittorrent) and eMule, domestic users can access the global file sharing network, or the global piracy network, basically without barriers.

However, because of the download speed, many people need to hang up for a whole day to download a popular movie, and it will take longer if it is an unpopular documentary.

The principle of P2P peer-to-peer download software is that when the uploader uploads the file to the Internet, the software will use an algorithm to "round the file into zero" and divide it into a large number of small data blocks, and at the same time retain the method of "turning the parts into a whole" on the server and restoring the normal file. Other users' clients get this list of data packets through the BT torrent file or eMule address, and they can download data chunks from other users who have these data packets through the software, and at the same time, the data blocks they have downloaded are automatically uploaded to other users, and after the data blocks are collected, the files are restored and the download is completed.

Therefore, in addition to the resource publisher in the P2P download method, everyone is a downloader and an uploader, which greatly increases the upload bandwidth, and the more people participate in the download, the faster the download speed, and the more resources of the same data block on the network are not easy to fail.

In this era, whether at home or abroad, everyone still holds a kind of Internet sharing spirit to do this, and there are often people who respond to requests to make up files, and upload resources for other users for a long time.

However, there is no shortage of egoists, some people turn off the upload function when downloading, or limit the upload speed; some people quit the p2p download software immediately after downloading and no longer upload; there are also pirates who download American blockbusters and free subtitles shared by netizens on their computers, package and compress them into pirated DVDs, and sell them for profit.

In a sense, the sales of "hard disk version of film and television resources" that Atletico Madrid came into contact with are of the same nature as pirates, and the only difference is the scale. Many of the professional pirates are large optical disc factories, and their output is measured in 10,000 copies.

And these sellers who sell hard disk versions of film and television resources are all working alone, with a network cable, a PC, a few hard disks, and a Taobao account opened. Many people may just want to recover some electricity bills generated by hanging up downloads by selling hard disks at a higher price at the beginning, and then slowly expand the scale.

However, small water pipes are always small water pipes, and such a business was born because of the small network water pipes, and because the small network water pipes severely limited its scale. A DVD disc can only hold one movie with mPeg-2 encoding (DVD standard encoding, backward era, lower compression ratio and larger size), but a 160gB hard disk can put more than 100 RmVB (the patented video compression format developed by Rm company, smaller in size, the most popular video compression format on the Internet at this time) format of the film, if you use mP4 (mPeg-4, a new generation of standard compression format, more used abroad) format, you can even stuff 200 films.

At first, Atletico just happened to see someone selling these film and television resources with a hard drive on Taobao,Considering that the genuine version can't be bought,Online download is too slow,He tried to buy a piece,Although it's just an ordinary movie collection,But after sorting and analyzing through e7u,He got 1579 kinds of faces、321 kinds of plants、304 kinds of houses and buildings、208 kinds of cars、87 kinds of animals、13Part of the data of the aircraft。 These buildings, vehicles, plants, animals, and faces were also added to the development material library of fantasy TV series.

Overjoyed, Atletico Madrid began the process of searching for hard drives all over the world. It is indeed all over the world, at first it was only to buy domestic sellers, but after a period of time, it was found that the duplication rate of documents was getting higher and higher, and Atletico realized that the domestic resource inventory should have been emptied by him.

Either these sellers "plagiarize" each other, or they all download resources in the same place, causing their resource inventory to get closer and closer. At this time, Atletico Madrid, who had collected thousands of domestic TV series, was really disgusted with the domestic film and television city - he found that he saw the same inn in 13 TV series, the same string of spicy people in 23 TV series, the same Japanese in 18 TV series, the same palace in 9 TV series, and the number of appearances of a certain tree was even more innumerable......

At this time, you can only turn your attention to foreign countries, although foreign sellers do not use payment packages, but they use PayPal as the prototype of payment packages, in fact, there is not much difference. After opening a foreign currency account and activating PayPal, Atletico began to receive hard drives from overseas.

Because of the problem of repetition of content when buying in China before, Atletico Madrid specially designed an inspection software. Before payment, he will leave a message through the chat software to ask the seller to connect the hard disk to be sold to the computer, and use the designated "folder previewer" tool software to scan and generate a preview file and send it to him. And this file scanning gadget uploaded to hundreds of download sites around the world, although the name and uploader are different, in fact, the author is Atletico himself.

These software can quickly scan a large number of files and generate text information containing file name, size, creation date, modification date, and MD5 check digit. At the same time, the software will also call the system decoding plug-in to create thumbnails, screenshots, and compressed audio clips for some pictures, videos, and audio files, and with these preview clips and highly unique MD5 encoding, it can greatly avoid the problem of file duplication.

These text messages, thumbnails, screenshots, and audio clips are automatically encapsulated into a compressed package, which is re-compressed to reduce the time consumption when transmitting over the Internet. The person receiving the package decrypts the package using the key provided by the sender, and can view the list of files and thumbnails inside.

In this way, the size of the thumbnail file is greatly reduced due to the secondary compression of the compressed package, which greatly avoids the problem of "multiple images killing cats" when looking for resources.

This "cat" is not a cat cat, but a moDem (modem), which is used to modulate the digital signal of the network cable into the analog signal of the telephone line, so that the user can use the telephone line to access the Internet (dial-up Internet or aDsL "wide" band).

"Multi-image killing cat" refers to the fact that the web page is too large and too many pictures cause the web page to load for too long, and it feels like the "cat" is dead if it can't be opened for a long time, of course, it is also possible that the "cat" is dead, or even the computer is dead......

This thumbnail function was originally specially prepared by Atletico Madrid for himself, and all the content that Atletico has downloaded is in his mind (in fact, it is in the e7u organization under the skin of the whole body), and you only need to look at the screenshots and thumbnails to know if you have relevant content here. Others are still using the same "Folder Previewer" widget more quickly than using their own inventory, but this will not rule out duplicate files that are watermarked and cause the MD5 checksum to change.

However, because Atletico Madrid's algorithm for intercepting clips is more intelligent, you can always find information with content, unlike other software that captures preview pictures often intercepts inexplicable pictures, so it has gradually been welcomed by many users who do seed uploads, and some users who can't find the picture bed (network public album) to put the preview picture directly upload BT seeds and the corresponding "preview package" at the same time, or simply package and upload the "preview package" together, and slowly more and more users use this gadget.

This is not the first time that Atletico Madrid has contributed to the development of global file sharing, and he found bees in the hard drive he bought before.

Bee Handling is a professional download tool in the Bee series software, and it is the world's first download software that supports the "BM" download protocol.

"Bm" is a portmanteau of "bittorrent" and "emule", and the two letters of the name come from the two most popular P2P file-sharing protocols, respectively. Bee Carrier supports both BT and emule download methods, and integrates the two, so it supports BT network, ed2k network and kad network at the same time.

The ed2k network is a dedicated P2P file-sharing network for eDonkey2000, the most popular downloading software two years ago, and each running client sends a request to the server, which returns a list of other users, and the user's computer contacts other users to start file downloads.

Because ed2k has a large number of pirated music, film and television content, which harms the interests of the Recording Industry Association of America (RIaa), eMule lost the lawsuit last year and was fined $30 million in compensation to RIaa and permanently stopped development.

However, because ed2k is a P2P-based network, defeating eMule and stopping the development of eDonkey software (eDonkey2000) will not stop the operation of the e2K network. As a result, RIaa began to pressure countries to take down their own ed2k servers through lawsuits, and in February this year, the world's most popular server, Razorback2, which has more than one million users, was seized by the Belgian federal police.

Since then, there have been a number of "uneasy" servers on the ed2k network, which offer very few search and source lookup functions, and these servers are said to have been set up by copyright owners such as RIaa in order to destroy the ed2k network and gather evidence of pirated users who have violated copyright laws.

Therefore, the successor of "eMule", "emule", has added support for the KAD network in addition to the original ED2K network support, in order to combat the increasingly bad server environment on the ED2K network. The Kad network uses the Kademlia protocol, uses a distributed hash table computing system, and the file search function relies on each networked user to complete, getting rid of the dependence on a central server.

Emule is an open-source software, the new version has both a Windows installer for ordinary users, as well as a source file for developers, and anyone can modify and improve it by themselves, which makes emule update very fast, with an update every few weeks. After the electric donkey was banned from development by the court, the electric mule took over the banner of maintaining and upgrading the ed2k network, and in China, the most popular cD download website cD Chinese version of emule, added a Chinese interface and some functions suitable for domestic users, and removed some original emule functions, so it attracted a lot of criticism.

Because BT and emule are both open source software, many download software around the world have added support for both, so "compatible with BT, ed2k, kad at the same time" is not the originality of Bm download software, but as a "genius programmer" who is open, how can Atletico's work just stop there?

Even the domestic Lei Xun 5 has to "target the habits of domestic users", and the upload rules cancel BT's "golden rule: the more you get from a user, the more feedback, the less you get, the less feedback you get", and turn into a "vampire donkey", "vampire BT", BM naturally moved some tricks on the protocol.

The biggest change to the BM software is in its name, on the one hand, the BM protocol is "really" supporting both BT and emule, as the name suggests. This "really" refers to the fact that Bm can step on two boats and get file data streams from both the BT network and the emule network at the same time.

On the other hand, "Bm" is also an acronym for "Confidential", and "Bm" strengthens the encryption of users' IP addresses and file information, making it difficult to trace.

However, Atletico Madrid is a little crying and laughing at Bm's feeling of going abroad to study abroad, and there is a kind of self-inflicted depression.

Out of respect for open source software, because Bee Carrier uses the relationship between bittorrent and emule code, Atletico Madrid also open-sourced Bee Transport, although the source code is not fully published, especially the source code of the core Bm download engine, but it provides analysis of the source code of other peripheral modules, and any skilled programmer can turn other download software into Bm core through file replacement.

Therefore, what Atletico Madrid saw in those bought hard disks was basically not the original bee handling software, but various modified versions of various Chinese versions.

Of course, Atletico Madrid did not regret the open source bee handling, but was depressed by the results of the open source bee handling.

Foreign open-source software authors are still very disciplined, the software uses the source code of Bee Transport, and the copyright note of Bee Transporter is added to the "About" interface, and even Atletico Madrid also saw the content of the hB typesetting engine that cites Bee Browser 2007 in a download software. Although the interface layout of the download software is a bit rudimentary and there are not many animation effects, it has a lot of inspiration for Atletico because of the fast loading speed due to the use of a web typesetting engine.

To Atletico's dismay, the "BM" download engine adds some security and confidentiality to online P2P sharing, with the result that they are used to transfer illegal files over the network. Of course, this "illegal document" is not only pirated songs, pirated pictures, and pirated films, but also all kinds of pirated or "original" adult videos, especially some of them that infringe on more social taboos.

According to estimates, there are 30% of adult content on the Internet, and this proportion is an estimate for the whole network, and in the subdivision of pictures and film and television downloads, this proportion will increase a lot. After all, it is too easy to shoot adult video works, and it is fast to shoot a movie in a month, while an adult video only needs a "performer", a digital photography equipment, and even a home digital video camera, PC camera, and mobile phone camera can be shot in ten minutes and half an hour. The same professional videographer needs to repeatedly find the best match for the model, scene, light, and pose to take a satisfactory photo, and the adult photo only needs to take off the shutter, and its output is naturally much higher.

Atletico didn't expect this result, and now there is nothing to do about it, after all, the bee handling has been open sourced, the Bm engine has been widely used, and it is usually difficult for him to interfere with anything in the normal way. Besides, teaching bad children or something is also a headache for crooked nuts, and it's about our gods?

"But this bastard made this white girl really tender-skinned, is she 15 years old?"

"Atletico Madrid, what are you smiling at?"

Just now, Liu Shumeng turned around and planned to talk to Atletico Madrid, but found that he was sitting motionless in front of the computer, and the computer screen displayed the login page of Langhua VOD background management, as well as a red word prompt: "You have not moved for a long time, please log in again!"

"Uh-uh, nothing, nothing!" Atletico said quickly, blinking his eyes and moving his dry eyes from the long daze.

"Nothing, you've been staring at the computer login screen for so long? Isn't it reminiscing? ”

"I reported that the fourth child was not in the dormitory in the morning and came back after lunch. Li Jiaming interjected.

"Second brother, you don't seem to be in the dormitory in the morning, how do you know?"

"I was in a hurry to leave in the morning, and I forgot to bring my wallet and mobile phone," Li Jiaming spread his hands, "I can't remember your mobile phone number, I just thought that there are two house gods in our dormitory, you and Atletico Madrid, no matter how you do, there should be someone in the dormitory, so I called the dormitory phone, but no one answered!"

"Isn't this just the right place to eat on the same plate as your Xiaoli? Maybe you did it on purpose!"

"How do you know ......?" Li Jiaming asked anxiously, but the engine quickly turned off, needless to say, this must have come from the 717 girls' dormitory.

"Hahahaha," Liu Shumeng, who provoked the topic, covered his stomach and bent over to laugh wildly, "Hahahahahaha......"

Atletico Madrid and Li Jiaming looked at each other and couldn't help laughing.

Liu Shumeng, who was smiling so painfully, stretched out his hand to gently press the iliopsoas muscles, and said while panting: "You two, you have found two girls from 717, if you can go to the end in the end, you are still big and small immortals." Maybe you were all thoroughly analyzed and compared by the girls of 717 during the talk. ”

"What is a big and small immortal?"

"It's the brother-in-law of the written word, Jiaming, and the same door they said there. ”

"Oh, it's brother-in-law and brother-in-law?" Atletico looked at Li Jiaming proudly, "Hello brother-in-law, goodbye brother-in-law!"

"Brother-in-law, your sister, in the 408 dormitory, you have to follow the rules of the 408 dormitory, you have to call me the second brother, and your Tang Jiayi has to call me the second brother. ”

"So, 'second brother', you finally used today's 'eating a bowl of rice together' to get the 'second sister-in-law'?"

"That's a matter of course!

"Your sister, your sister. Your sister, your sister, your sister—" At this time, Liu Shumeng muttered in a low voice beside him.

"First of all, you have to have a sister, whether it's a sister or a cousin. Atletico turned to Liu Shumeng: "Third brother, you have to hurry, the second brother successfully stripped naked when there were 40 days left in 2006, and the boss seemed to be hurt and didn't want to fall in love, so you are left in our dormitory." ”

"Fourth, what you said is not right, whether it is a sister or a cousin, you can't fall in love, and the marriage law does not allow it. ”

"What are you talking about?

"The third child has brain poisoning, right?"

"But the second one, this 'your sister' you invented is really quite emotional to say. ”

"Your sister, if you want to call the second brother, and then call me the second brother, I will be anxious with you!"

"Haha, that's quite emotional, isn't it?" mobile phone users please visit http://m.piaotian.net
