The dimly lit machine room was deep and quiet, with only the sparse gurgling of liquid flowing and the faint hum of the motor spinning, and the source of the latter was not fixed, far and near, indicating that it was the sound of the machine room robot patrolling the machine room along a predetermined route. The red, green, blue and white dots of light on the cabinet blink like stars, but they are using different colors and frequencies to convey different information, and only those robots that walk through it can "understand" the meaning of these blinking dots and respond correctly.

This kind of robot is not beautiful, it is composed of a small two large three stacked discs on a slender square rod, the center of the thin rod more than one person high has a fine toothed structure, and there are also gears on the inside of the upper and middle two discs. The motor drives the forward and reverse rotation of the gear, which can make the two discs move up and down along the square rod guide rail.

These three discs are the head, shoulders and crotch of the robot, and the small disc that acts as the head has a variety of sensors on it, which can sense the distance and direction, and is equipped with a high-definition camera that can recognize the meaning conveyed by the LED flashing of each joint on the rack and its "arm", and drive the arm to steer flexibly.

The lower disc that acts as the crotch and the central square rod are fixed together, and three wheels arranged in an inverted zigzag pattern are installed under it, wherein the front pair of wheels are respectively driven by an electric motor, and the forward and backward of the robot can be controlled by adjusting their speed difference to various directions.

Two mechanical "arms" are symmetrically mounted on the disc in the "shoulder" of the robot, and instead of using a complex structure similar to the joints of humans and most animals, they simply use rotating joints, each with four rotating joints that can rotate 270 degrees, making this robotic arm look like a "bow" zigzag bending and bending without much beauty. But after all, this is an industrial robot, why do you want a beautiful and generous mountain bike?

Although this kind of robotic arm that uses a motor and gear set to realize the three-in-one joint, drive device and control device has the problem of "no strength" with low torque, it is superior to the simple structure and low cost. And its torque is enough to complete the scheduled maintenance work of the machine room, after all, with the now popular blade architecture, there is not much physical work left for the machine room work.

Although the digital biology company is famous for its Xiao'an robots, the product they sell the most is this kind of computer room maintenance robot, although their intelligence is not as good as Xiao'an, who can successfully pass the Turing test (playing the role of a human and chatting with other humans is not recognized), but it is completely fine to complete the general daily inspection of the computer room and the isolation and replacement of damaged equipment parts instead of the staff. And although they are rigid and mechanical, they can implement the preset plan at a glance, and will never cause various man-made accidents due to brain pumping and misreading. At the same time, it can also be switched to remote control mode when necessary, which can be remotely commanded and controlled by the staff, which further improves the usability in special situations.

As soon as he walked into the bee computer room and saw the dim working environment here, Liu Shumeng complained about Atletico Madrid's slamming of the door: "You bees really lack that little bit of electricity, and you can't even afford to light a lamp?"

Atletico shook his hand: "It's an international trend that the lights don't turn on in the computer room! For example, Google's computer room doesn't turn on the lights, and the maintenance personnel wear miner's lamps on their heads to patrol inside and replace hardware." ”

"What is Google? Don't fool me with non-existent websites!" Liu Shumeng responded to a joke that was gradually circulating on the Internet. As soon as the news content mentions Google, Facebook, Twitter, lure tube and other websites and services that cannot be directly logged in and used in China, some netizens will post some things in the comment area such as "Don't keep using these non-existent websites for water news, I'm not fooled, hum!"

It's not that they don't know the truth, it's more of a joke, but if it continues, maybe in a few years or a dozen years, these sites will really be forgotten.

Google's main reason for turning off the lights in the computer room is to protect trade secrets, and the lights in the computer room and cabinet lights that are turned off are mainly in the third-party computer room, because there are cabinets placed by other manufacturers in these third-party IDC data centers, and Google deliberately turns off the lights so that outsiders will not see the configuration of their servers. As for whether Google's own computer room is turned off or not, no one knows, because Google rarely discloses the details of its computer room, after all, this is a trade secret and competitiveness.

And the bees turn off the lights in their own computer room, not only for the purpose of saving money, but also for the purpose of keeping secrets.

"Robots don't need lighting, they can use the LED lights on the motherboard for positioning, and if necessary, they can also use the LEDs on its body for lighting, so they don't need to turn on the lights, and these electronic products, cables use a lot of organic materials, plastics These things will age under the light, and turning off the lights can delay aging, prolong the life of the equipment and reduce the failure rate. ”

With the pace of Atletico Madrid, the lights above their heads are lit up one after another, and the lights behind them are automatically extinguished, creating a visual effect similar to the stage spotlights chasing you, which is also not for playing romance, what romance is there about the three big men, after all, they don't believe in King Billy, this is still to save money.

Speaking of the topic of saving money, Liu Shumeng pointed to the rack and said: "It is said that it is very cost-effective to use PS3 pig supercomputer, because Sauni sells hardware at a loss and buys it to make money, and even Meifu has to pull a few cars of PS3 back to form a supercomputer, and you bees don't buy thousands of units?"

"The Cell processor of the PS3 is indeed very powerful in terms of floating-point arithmetic, and it can also be very convenient to form a grid computer, but if I plan to form a Cell supercomputer, why don't I go wholesale a car of Cell processors back, why spend $400 to buy a PS3?"

Cell is a Japanese SC architecture processor for game and video processing cooperated by IBM, Sony and Toshiba, consisting of a simplified PowerPC970 core and eight coprocessor cores, with strong floating-point computing power, and Cell holds the fastest processor clock speed record on the planet so far: up to 4. 6GHz!, Intel had to switch to a multi-core architecture after the failure of the Pentium to hit the main frequency above 4G, and maintained the "Pentium" brand that emphasized that the main frequency is performance, and instead worked hard to promote the new Core brand with a lower frequency and multi-core cooperation.

However, Cell can run so fast because it is a Japanese SC reduced instruction set architecture processor. In the field of processors, people also found the existence of the 28th law: the usage rate of 20% of the instruction set is as high as 80%, so the Japanese SC reduced instruction set architecture was designed, so that the processor only supports the most commonly used 20% of the instruction set, which greatly simplifies the internal structure and significantly improves the execution efficiency. Therefore, with the same number of transistors, the daily SC (Poips/Loongson) and CISC processors (complex instruction sets, the most typical is X86), the former can complete more instructions in the same time and the main frequency is faster.

Of course, for the 80% instruction set that has been discarded, the Japanese SC can only rely on the software to decompose and convert it into the instruction set supported by the Japanese SC, which will inevitably bring a huge loss of efficiency. Therefore, the two architectures have their own advantages and disadvantages, the daily SC has good performance and low cost when performing certain tasks, and the CISC is more convenient for dealing with a variety of tasks. Nowadays, the pattern of X86 for PCs, ARM for small mobile phones, and large-scale computers is gradually formed for this reason.

Interestingly, Apple Computer once stepped on two boats, and participated in the PowerPC and Arm two improved Japanese SC architecture camps, and their Mac computers used to use the PowerPC processors manufactured by IBM to develop Motorola, but after 06 they abandoned it and joined the Intelx86 camp. At the same time, Apple is also a major shareholder in the British company Arm, which is now the main technology provider for mobile phone processors, and also used early ARM chips to make Newton PDAs. Compared with Android and Nokia Meego that are bluntly modified from Linux, iOS from macOS obviously inherits the rich experience accumulated by the former for many years running on Japanese SC architecture processors. At that time, Nokia ridiculed Apple for not knowing how to make mobile phones, but people understood the chips of mobile phones, and the result was moved from the core, and then Nokia was the cup.

Of course, in terms of using Japanese SC processors, Atletico Madrid and his Bee OS are also in the world-class camp, at least on the same level as Apple, but people are original and can use these experiences and technologies in a big way, so he has to be careful to hide it, resulting in a greatly reduced effect, which is only a little stronger than the Android system. In addition, Bee OS does not have as many awesome "godfathers" as Android, and the brand awareness is not too high, resulting in the fact that although the bee mobile phone has been listed for a long time, it has been said to be good, but its production and sales have been surpassed by competitors one after another, and it seems that it has gradually become a trend of non-mainstream. Now, although Atletico Madrid has also developed the world's advanced mobile phone processor, due to some policy reasons, their chip production is required to be placed only in China, and because of SMIC's backward technology, the performance of the first generation of bee's independent chips is not excellent, which also affects the market evaluation of the third generation of Bee mobile phones.

And on the server that belongs to Bee Bee itself, Atletico Madrid can naturally use the code he got from the strengths of others, and now there are more carbon tube processors designed and produced by him, which is why no one should be managed and the lights should be turned off in the computer room.

However, Atletico Madrid's secrecy measures are quite good, and the carbon tube chip he made entered the Bee computer room Earth in the form of a fake chip, not Motorola

Freescale's 56800 chip is polished like Hanxin, but his carbon tube processor is polished to the appearance of Intel processor, mixed with other genuine processors for use, and the dedicated server operating system that Atletico participated in writing and modifying has also been updated by him with special components for carbon tube processors, so as not to cause chaos. On the one hand, this is to save themselves money, and on the other hand, it is also to put them on the front line for practical verification.

Although these processors are tightly covered by water-cooled radiators, there is no way to see the number on the chip shell, and there is no way to verify the authenticity, but after all, the "weak heart", Atletico simply made it like this by protecting trade secrets.

The cookie-cutter, quiet and unmanned computer room is actually easy to get bored, although not everyone has a phobia of denseness, but this spectacular scene of dense racks full of huge spaces will still have some impact on people's emotions, so soon Liu Shumeng lost interest and ended the visit. Basically, everyone who comes to visit the bee computer room will turn back without going far, after all, just look at the beginning, and the back is "repeated", so there is no need to read it.

After changing his clothes, taking off his head and shoe covers and changing out of the white coat, Liu Shumeng's mood was obviously a lot better, the feeling of wearing the extra-large white coat just now was not very good, the white coat provided to visitors here was only four sizes of large, medium and small for visitors, his figure was a little squeezing his stomach in a large size, and he felt very uncomfortable wearing a large size but wearing a loose body.

Although the place they are going to visit next is also not allowed to take pictures and videos, the requirements for clothing are much more relaxed, as long as it is not a vest, slippers and pants, it is basically no problem for the old man in the alley.

Walking into Atletico Madrid Walking into a brightly lit hall, Liu Shumeng saw the dense computer monitors at a glance, as well as the black back of the head standing in front of the monitor, most of the men's short hair, very few ponytails, looked like mm.

This is the Bee Multimedia Content Management Center, responsible for managing and reviewing the manual review of the pictures, videos, audio and text content uploaded by users to the garden space, and is also responsible for the review of multimedia content in fishing net search and other bee services.

Indeed, standing at the door and looking in, most of the pictures that appeared on the screen as far as Liu Shumeng could see were flesh pink, wheat, and off-white patterns, and their common characteristics were relatively "yellow". He turned to the other side of the doorway, trying to see the faces of the people on this side to determine if there were any beautiful women, only to find that everyone was wearing all kinds of masquerade blindfolds on their faces, and for a moment they did not distinguish between men and women.

Although the accuracy rate of Bee's AI-based content management system in identifying violent and illegal content is very high, it still cannot reach 100%, so Bee has established this large-scale pornography identification center and organized trained manpower to manually identify some content that cannot be determined by software.

"Because of the special nature of the work, we don't have permanent staff here, but we ask employees from other sister departments to submit applications, and then we seconded them. And after working for a period of time, they will return to normal work, in order to avoid embarrassment in front of acquaintances, everyone can choose to wear a blindfold to protect themselves before entering here**. The deputy director of the lecture noticed Liu Shumeng's movements and explained that the blindfolds and anonymous censorship are also a major feature of the Bee Yellow Identification Center, and almost everyone who visits here will notice these blindfolds.
