On Saturday, April 1, 2006, the first Chinese test of the April college entrance examination mock test for the third grade of Pingxian No. 2 Senior High School was underway.

Atletico returned home, turned on the screen, connected the power cord and water cooling pipe, and turned on his Bee computer.

This heavy-duty laptop or portable desktop, which he "designed" and assembled himself, has been modified and modified several times by him, mainly on the one hand, the hardware has modified the cooling system, and the software has been upgraded to the new honeycomb operating system and supporting honeycomb application software.

The previous water cooling system was found to have insufficient heat dissipation capacity, and although the heating parts such as cPu and gPu did not reach the dangerous temperature of 90 or 100 C, the temperature continued to be above 60 C during operation.

This is obviously not good, as prolonged high temperatures can cause severe aging reactions to plastic components, shorten the service life of parts and bring safety hazards. Therefore, Atletico Madrid went to find materials to make an external more powerful water cooling radiator, and at the same time modified the built-in water cooling radiator.

This renovation is very serious, carefully calculate the flow rate of the pump, heat exchanger and other data, comprehensively consider noise, volume and other factors to carefully design and select, and then many tests to complete the new 1+1 water cooling system.

When only the built-in radiator is used after the transformation, the internal heat is absorbed by the cooling water that passes through the heating part, and the cooling water flows through the curved copper tube inside the long radiator under the screen, and the well-designed fan blows strong wind through the surface of the copper tube, in which the temperature of the cooling water decreases rapidly, and the hot air blown through the copper tube is blown to the back of the computer.

The fan speed inside the heatsink can be adjusted in a wide range, and the minimum operating temperature can be maintained at about 20C above room temperature, and if the weather is cold, the fan speed can be reduced or even turned off, so that the entire keyboard area becomes warmer.

After the external radiator is turned on, the cooling fan no longer works, but the cooling water of the external radiator flows through the surface of the copper tube, which has a better cooling and mute effect. Atletico has equipped the external radiator with a 20-metre-long high-strength hose that allows the external radiator to be placed as far away as possible, completely avoiding the noise and heat source pollution of the radiator. According to calculations, an external radiator with a large bucket as a cooler can reduce the computer to less than 10C above room temperature, even if the room temperature reaches 40C.

In order to facilitate himself and Tang Jiayi to chat about text messages, Atletico Madrid helped Tang Jiayi crack her mobile phone and reflash the mobile phone system, which supports Bluetooth and even direct communication of baseband antennas. This matter was also told by Tang Jiayi to a few good classmates, of course, she said that she was cracking and optimizing Bluetooth, and at the same time adding cute emoji functions, which resulted in a lot of business for Atletico Madrid.

At first, Atletico Madrid just helped Tang Jiayi's good friend and a few of his own classmates and friends with good relationships to brush the system for free, and later more and more classmates came to him for help, and even classmates who were not in class 1 and class 7 came to the door. In order to block people, Atletico Madrid simply offered a fee banner, swiping a mobile phone to charge an upgrade fee depending on its price, 50 yuan below 500 yuan and 100 yuan below 1000 yuan, which suddenly reduced ninety percent of business requests.

But the remaining business still keeps him busy, and now he still has three mobile phones to flash.

In fact, with the powerful speed of the E7U, it doesn't take much time to change the "operating system" of the mobile phone. Almost a few seconds after Atletico made contact with the phone, the e7u cracked the phone's "operating system", and then modified it on the basis of several preset templates according to its hardware configuration (adding or removing the driver code of specific hardware), and finally packaged to generate a new system and write it into the phone's Rom.

This is also the function of the mobile phone is relatively monotonous, many functions are provided by the corresponding hardware chips, the "operating system" function is just to drive these hardware to work normally, which is much simpler than the PC operating system.

But Atletico naturally can't be so "second-brushed", because it seems unprofessional. For example, although digital cameras have been miniaturized now, when people ask a wedding company to record a wedding celebration, they still feel that the videographer with an old-fashioned video camera on his shoulder is more professional. That's the importance of posture!

Therefore, Atletico Madrid will use 6-24 hours to help people brush their mobile phones, and the models that have been brushed before "only need" six hours, and the orders will be delivered at noon and in the evening, and the models that have not been brushed will take a whole day to be brushed.

But even so, Atletico's "business" is still very prosperous, without him, E7U is really powerful to install a new system on everyone's mobile phone!

Today's non-smartphones usually use JaVa, or similar languages, to write applications that drive the phone's hardware to implement various functions, leaving very little free running memory and flash memory space for third-party software.

The most well-known advantage of the JaVa language is its excellent cross-platform features, which can be easily ported from one platform to another. In order to achieve cross-platform capabilities, JaVa uses the JaVa virtual machine to isolate the application from the computer hardware, and the software does not care about the specific hardware model, just needs to send requirements like the Java virtual machine. Because the application cannot send instructions directly to the hardware, JaVa cannot use 100% of the hardware's performance.

When Atletico Madrid is swiping mobile phones, the "operating system" provided by E7U is completely a set of software written using machine code, which can maximize the full performance of the hardware on each mobile phone.

The lowest level of the software programming language is the machine code of 0101, which can be executed directly on the computer, but it is very inconvenient for human engineers, and later it was written with hexadecimal numbers to shorten the code length, and then engineers invented mnemonics, resulting in assembly language. And then on the basis of assembly language, high-level languages were invented, such as the very popular C language.

The advanced aspect of high-level languages is that they are easier for humans to understand and use. Just as the more powerful true 64-bit cPu was defeated by the 32-bit cPu patch upgrade, machine code is rarely used directly. Although machine code programming, which is inconvenient to use, can give full play to 100% of the hardware performance, it is ultimately inferior to high-level language programming, which is easy to use and can give full play to most of the hardware performance. Of course, software programmed in a high-level language needs to be converted into assembly language by a compiler, and then translated into machine code again when it is actually executed - the machine always recognizes only the machine code.

However, the difficulty of using the machine code is naturally not a problem for the E7U, which is a "machine" itself, so it can easily write the machine code software for each mobile phone based on its own hardware situation.

Atletico Madrid's mobile phone upgrade business is especially popular with students who use copycat machines, and miscellaneous copycat machines are all a one-shot deal, and they dare to write anything on the box except for the contact information of the factory address. So naturally you don't have to expect any after-sales service, firmware upgrades, and a lot of third-party software. Therefore, they also disagree with the warning of Atletico Madrid's warning that "flashing leads to illegal after-sales agreements and automatically abandons after-sales service".

Besides, Atletico Madrid here upgrades the phone to provide customization services, so that your phone's limited memory space can be loaded with as much software as you need.

If Atletico can improve the ease of use of the brand's mobile phones by 10%, he can reach 30% on copycats - the system design of some copycats is really terrible!

Atletico Madrid has been exposed to a large number of mobile phones that have not been comparable in the past three years in the past ten days, and he also has some ideas about the composition of the low-end mobile phone market in Pingxian, and he is particularly interested in the mTK platform, a cutting-edge force in copycat machines.

The mobile phones on the mTK platform that Atletico Madrid came into contact with are very similar except for the appearance of the shell and battery, and the hardware configuration and operating system are the same. The overall performance is also the best among copycat phones, and he thinks that mTK is likely to summarize the chaos of domestic miscellaneous mobile phones.

In the future, everyone will be the same inside, and they only need to spell the appearance and price. For mobile phone users, please visit http://m.piaotian.net
