"Air Conditioners" in software development)

It is said that in a rich country in Africa (the Gold Diamond made in China), the climate is hot and energy is short. This country does not have an air conditioner yet. Two people also saw the market prospect of air conditioners in this region, so they were eager to invest in this direction.

Mr. Jin, surnamed Jin, is the head of a construction company. He sent his staff to take a large sum of his money to set up and manage a new air-conditioning R & D Company. This employee is surnamed Mi and is a doctor of architectural aesthetics.
Another name is "dill". He picked a doctor of market economics in his company, Andrew. With a large sum of money from "dill", he also set up and managed a new air-conditioning R & D Company. Coincidentally, the two companies were established and started to operate in the same way. They were all in the city as a light pole commander, plus a large amount of money. The stories of the two companies have just begun.

On the first day, Dr. Mi and Dr. Andrew both thought that they were not experts in this field, so they all thought of finding a refrigeration master in the talent market. Fortunately, Dr. mi found Master Meng, and Dr. Andrew found Master knuth. Both of them are experts in this field. So the first day passed.

The next day, I started thinking, how can I combine my professional knowledge to play a greater role? I finally thought about it. The air conditioner's external host should be designed to meet the architectural aesthetic requirements. As a result, mi sends the first command to Director Meng to design an external machine with a triangle. Director Meng is very surprised. How are the things in the triangle chassis arranged? In addition, the compressor should be designed or purchased by itself. What model should it be used ...... This pile of questions asked rice, rice said: I won't, technical issues will be handed over to you. Meng was so depressed that he had to go back to his office and design it. On this day, Meng designed an all-night design in the office.

Andrew was also thinking about the other side, but another question: what kind of air conditioners can sell more in that country? After half a day, he found that the country's energy was tight, so the power-saving and efficient products should be more marketable. Therefore, knuth agreed to ask for knuth's opinion. So Andrew asked, What should I do if I want to save power and efficiency? So knuth said a lot about the relationship between power consumption and energy consumption between compressor, heat sink, and fan, although Andrew does not understand either, however, I still listened to it. Finally, Andrew agreed to the knuth solution: first, he studied the compressor, then the heat sink, and finally the fan. After the meeting, knuth returned to his office and started an all-night design.

On the third day, Mr. Mi, in order to verify his own ideas-whether there is a need for external machines in line with architectural aesthetics, took the drawing designed by Director Meng last night, he went to the country in Africa to find his old construction industry friend for proof. The result of the authentication is depressing. His friends have never seen air conditioners and do not know what they are. But I can't explain it myself, because I don't know what the compressor in the Design book is like. Let alone what heat efficiency refrigerant is. At last, mi had to open the Design book and discuss the appearance of the design drawing with his friends. His friends thought it was not pleasing to the eye: how can it be a triangle? Currently, all the buildings are sleek, so the edges and corners are neither popular nor conform to the African architectural style.

Mr. Mi rushed back and complained to Director Meng about the Design book which he could not understand and could not use. Let alone those who have never seen air conditioners do not understand, even those who use air conditioners all day long do not know what you are talking about! Oh, by the way, you have to change the shape of the chassis. You cannot change the shape of the triangle to a circle. Is this simple? Just change the shell!
Director Meng had to say: 1. This manual is only for internal designers, basically for internal implementation details. 2. It looks very easy to change the shape, but the placement of internal devices is a matter of injury. For example, the original compressor is a 60-degree tilt angle, which is followed by a triangle side. Now it is a circle, which is not applicable. There is also the heat sink ......
I have a headache when I hear about the compressor and the heat sink. I have no right to speak about it. In short, the market feedback now requires a Circular Shell, give me a usable product tomorrow! Not mature, unstable, or even Uncooled!
Meng thought it was not a general depressing situation, so he had to hold a pile of reference books to continue designing an overnight plan.

Knuth has built a simple platform with only bare compressors and a set of testing instruments. Throughout the night, he kept doing experiments, from mechanical implementation in the compressor to refrigerant selection, from self-designed products to products of other brands, I even made some improvements to products of other brands. On the third day, knuth reported the results of the experiment on the first night to Andrew. Andrew frowned at the beginning, because he could pat his chest and say that he understood nothing. However, Andrew was very satisfied at the end, because he understood a sentence: knuth's final compressor design is at least 12% more efficient than the best compressor in the current market. Andrew encouraged knuth to immediately study the next heat sink, while knuth happily corrected Andrew's mistake-it should be called a heat sink, then I was very excited to invest in the next stage of research.
In fact, Andrew was not idle yesterday, because he found that his knowledge in this area was almost zero, so he spent the whole night reading this book. Although the actual effect is not very satisfactory or even wrong, it knows at least that the compressor is the heart of the entire air conditioner, and 12% means that knuth is doing very well, this is enough for him. Andrew finally decided not to read those books today because he knew knuth was doing well and he had no need to worry about it. Another question worries him very much-is it true that the market demand is as he wished, and the need for power-saving and efficient air conditioners? So he decided to do something in that African country right away.
