Minke's black technology

Chapter 8 It's Not Scientific
Penguin company building, network disk department office.

Mr. Ha looked at the "Liquid Cat" software program in the computer, and shook his head secretly in his heart: "I don't know who came up with the name, and chose such an ugly name."

In fact, he didn't care about this software at all, it was just that someone asked him to take a look at it, so he reluctantly tried it out to see if the software was really as good as it was said to be.

"A compression ratio of ten to one? And lossless compression?"

Mr. Ha laughed secretly again: "I'm afraid this is used to fool laymen? Even if there is a compression ratio of ten to one, it must be lossy compression. I don't know how much data is lost!"

Thinking this way in his heart, his hands were not slow at all. He first randomly found a folder with a size of more than ten GB and dragged it there, and then clicked the OK button to execute the compression.

"Wait until the compression is finished!"

He wanted to make a cup of coffee to refresh himself and wait for the compression time to end, but before the coffee cup was filled with water, the computer beeped to indicate that the compression was complete.

"what happened?"

Boss Ha put down the coffee cup inexplicably, sat back at the computer desk, and checked the compression results with the mouse.

Judging from his many years of experience, there must be a problem with the compression software. There is no reason why a file of more than ten gigabytes can be compressed in such a short time.

"Is there a bug?"

Mr. Ha made a judgment again, but unexpectedly found a compressed file package, moved the mouse to check it, and it was only more than 1GB in size.

"Is it really only a one-tenth compression ratio?"

At this time, Mr. Ha still doesn't quite believe that "Liquid Cat" has completed the compression, and still judges based on experience: "It must have only completed a part of the compression, and you will know after decompression."

The decompression file can only be decompressed with "Liquid Cat", other compressed files cannot recognize this file type, and the decompression speed is very fast, just as short as the compression time.

After some operations, Mr. Ha showed a confused expression: "It's really all compressed, and no file data is lost!"

But he still didn't give up. He used the software to compare the original files. After the comparison, he still came to the same conclusion. The two files were completely consistent, and no data was lost.

"This is really amazing!"

Mr. Ha finally came to his senses, and planned to use this software for a while. He once again compressed a video folder of more than 100 GB, and then decompressed it for comparison.

It is still stable at ten to one. By comparing the old and new video files, we know that the data is not lost at all.

After this attempt, he was already shocked by this "Liquid Cat" compression software: "It can really achieve [-]:[-] lossless compression! What kind of algorithm does it use?"

At the same time, he also began to notice the usefulness of this compression software.

If the Penguin network disk department uses this compression algorithm, wouldn't it be able to save 90.00% of the network disk costs?No, it should be said that we can use 10% of the cost of others to achieve the effect of the current network disk service, thereby reducing user membership fees and occupying more market share!
Mr. Ha is eagerly looking forward to this software!
We must find a way to get it, or let the technology crack the algorithm in it, so that we have what other people don't have, and we must have what others have.

Thinking of this, he immediately took action: "Notify Xiao Zhang, let the technical team stop everything else, and wait for me to go to arrange urgent tasks."

"Okay, Mr. Ha." His assistant replied.

Xiao Zhang is the technical director of the network disk department and a technical expert who has been in the industry for many years. He quickly got the test software of Liquid Cat from Mr. Ha.

At first, when he heard Mr. Ha's talk about the compression ratio of Liquid Cat, he also said that it was absolutely impossible. After all, the compression algorithm has been developed for so long, and no one has ever been able to increase the compression ratio to such a high level all at once.

In his view, from the Shannon algorithm to the Huffman algorithm, the compression algorithm developed by the two has been used until now, and then the LZ20 algorithm in the 70s was a peak. The compression algorithm has basically been finalized, and no one has surpassed the predecessors. the scope of the study.

However, under Mr. Ha's insistence, Xiao Zhang reluctantly asked his subordinates to test it.

It's okay if you don't test it, but when you test it, you are startled, and Xiao Zhang shouts: "This is unscientific!"

The compression ratio of Liquid Cat can really reach ten to one, far exceeding the current compression software on the market. The current mainstream compression software ZIP, RAR, 7Z, etc., can reach at most two ratios under the restriction of whether there is compression or not. A unique compression ratio, and not all file types can achieve such a high compression ratio, only if there are a lot of duplicate data.

This software of unknown origin unexpectedly broke common sense, and suddenly achieved a lossless compression ratio of ten to one!

Xiao Zhang said in disbelief: "This is the compression ratio that can only be achieved by using black technology!"

"It's so unscientific! It's unbelievable!" Xiao Zhang repeatedly shook his head and sighed.

"I know this is unscientific, but the facts are in front of you, you should give me a professional judgment!"

Facing such black-tech software, Mr. Ha did not dare to make a decision lightly. He didn't know much about the details of compression technology, but he also knew clearly that if anyone could reduce the file size of the network disk to one-tenth, then Definitely save a ton of money.

Xiao Zhang, a technical expert, replied: "I can only say that this software is beyond the scope of my understanding, and I cannot give you an accurate evaluation."

In the end Mr. Ha decided: "We need to conduct a large number of tests, more rigorous tests!"

After some testing, the result is very good. No matter what file is compressed, it can stabilize the compression ratio at about ten to one, and the compression method is still lossless compression.

Penguin testers were full of praise for the compression effect of this compression tool, and were quite interested in the compression technology. This result also drove Mr. Ha to make up his mind. He called the monkey to the network disk department on the same day to ask questions about the compression algorithm. .

"Huh? You mean the algorithm here?" The monkey was dumbfounded by the question.

"That's right, can you tell me what algorithm this software uses to achieve such a high rate of lossless compression?" Xiao Zhang asked with concern.

"Uh, it's a commercial secret!" the monkey replied inscrutably.

How could the lecherous monkey know this? It would be better to ask the Ferry God than to ask him. However, under Xiao Zhang's persistent questioning, he finally accidentally slipped his mouth and let others know that the software developer is someone else.

"You mean, the author of the software authorized you to act as an agent?" Mr. Ha asked.

"That's right, he is a former colleague of mine, and his programming level is about the same as mine." Monkey replied bluntly, "However, he has been away from work for many years and has never gone to work. He spends time at home studying technical issues of compression algorithms. That’s how it came about.”

Under the hype of the monkeys, Li Maoye is described as a master who has lived in seclusion for many years, but he has become a blockbuster if he does not sing. The compression algorithm he has come up with now is just a small test.

It's a pity that Mr. Ha, the person in charge of the network disk, was not fooled by him, and he insisted on negotiating with Li Maoye about the purchase of patent copyrights related to "Liquid Cat".

This is not the result that Monkey wants. If he can't solve the problem of software sales alone, then his commission will be ruined. Li Maoye has repeatedly emphasized that he must not trouble Master Mao.

"Without the software author personally signing the contract, we Penguin would not buy this software!" Mr. Ha refused to approve the authorization letter in Monkey's hand, and asked Li Maoye to meet with Penguin.

In desperation, Monkey had no choice but to report the result of this contact to Li Maoye on QQ.

"Master Cat, this business must be negotiated by you personally!"
