Do you see the essence of the tool?

He believes that

Iron is harder than copper. This is common sense. In the Spring and Autumn Period and the Warring States, the yanguo's titanium blade has reached the hardness of high carbon steel today. This is already very impressive. In the Central Plains, the Xixi sword is the first of the nine famous swords. Xixi is located in xiping, spring and autumn belongs to Chu, and the Warring States belongs to Han. The famous master Zhu Jian once had ouye Zi, Gan CI, Mo Xie and so on, and the craftsman once reached seven thousand people. Shi said: "The sword of the world, Han Weizhong", that is, ZhuXi. Therefore, Yan, Chu, and other places are famous for their swords.

On the other hand, the 40 thousand weapons unearthed from the crater were almost all cast in bronze. However, we all know the result: Qin unified China by force.

Why can't I cut a bronze sword? Of course not.

From historical materials and physical objects, we can find that Qin Jun's sword is longer than that of other countries. According to analysis by weapon experts, the reason for this requirement may be related to a practical technique: with the same power, the thorn is more fatal than the cut, and the slashes are stabbed to death.

You will see this technique in many occasions. For example, in the movie "Lord of the Rings", you will find that the orcs take a big knife and humans use a long sword. At the beginning, both sides shouted with weapons and rushed to the enemy. But in the next war, the orcs were still cutting down, and humans tried to block them with swords and then stabbed them.

A good swordsman won't cut it with a sword. Most of the blade uses it to cut the apple. What really works is the sword tip. Therefore, a longer sword can be more easily stabbed to the enemy.

It is impossible in the history of war to generate a weapon that is more "labor-consuming" for no reason. Therefore, Qin Jun should have considerable practical techniques to take advantage of such a long sword to defeat the enemy. This technique has nothing to do with whether the sword itself is copper or iron, and whether the blade is sharp or blunt. The technique creates the need for a "long sword", so that the strengths of the long sword can be fully realized. In the end, the sword casting technology was no match to the Qin State of Yan and Chu, but the Yan and Chu were destroyed.

It can be seen that the method of using tools is more critical than the tool itself. Therefore, the comments such as "Seeking for good deeds and making good use of their tools" are not right.

What is the use of magic technologies?

However, far from being the most powerful sword in the Qin Dynasty, the most advanced fencing skills are not in the Qin Dynasty.

In the history of Pre-Qin Dynasty, the number of the most famous swordsman in the Yue Guo on the sword of the more female. She is the "swordsman's house, the winner of the battle" in the article. She told the Kendo, saying "the spirit of the inside, the outside shows the Security", with an air of emotion and a strong demeanor. In Zhao Guo, even Jing Ke admired the secret and went to the master of jiantao. In addition, Song Guo, The Lanzi (artist), who uses the sword technique as an art, can dance seven swords while running.

Go through the Pre-Qin history books and you will find this strange phenomenon: no dead man is Qin, no famous sword is Qin, and no master swordsman with any techniques is in Qin.

With regard to exquisite techniques, the Song Dynasty's Ouyang Xiu's "oil seller" is probably a real thing: Chen KANG Su Gong's good shot, when the world is unparalleled ...... Weng Yue: No, but skilled. 'Kang su angrily said: Er an dare to light my shot! '...... (Weng) is to take a gourd placed in the ground, with money to cover its mouth, Xu to the water, from the money into the hole, and money is not wet. Because: 'I have no other, but I am familiar with it. '"

Let's review this story. The technology of the oil seller is even higher, and it's not too much to inject the oil into the smaller money hole. He will never think of two things:

In fact, you only need to install the oil in the pot. It is not important to never add the oil from the money hole;

If the oil buyer only buys oil because he appreciates his skill of pouring oil, then he does not need to sell oil at all, and the promotion in the hall will be profitable.

In addition, the "Chen KANG Su Gong", that is, Chen Yao, the champion at that time, was a member of the Sichuan northeast region. Chen Yao was the champion of the state of the Union, but the arrow technology was called "Nothing in the world. Therefore, in the later Official Career, the permanent military officer.

At that time, archery was mostly a game skill. Chen yaozhi can "smile and send" to the oil seller. On the one hand, it is an open-minded nature, and on the other hand, it regards archery as a small skill. After he won the championship, Song zhenzong proposed to authorize him to take the role of martial arts. He tried the arrow technique with the messenger of Liao. His mother not only did not agree, but also blamed him. After that, he went home from Jinnan Zhifu and asked his mother what special achievements he had made. He replied, "all the guests praised my shooting skills ."

Chen's mother said, "I'm a husband, I'm a father. 'Press with a pin ".

Chen yaoqi is a good shot, but does not know why. He holds the title of "the technology of being a husband" to entertain people and entertain others. He never saw him fight for meritorious deeds and establish his own career. He pursues arrow techniques, but never knows that arrow techniques are not used to launch money-eye attacks, but to fight for the enemy. It is like a oil seller who only knows how to practice and pour oil, but does not know that his purpose is to sell oil.

You must know that Chen yaoxun is not a military talent. In his later years, Ren tianxiong (the military defense of Hebei East Road) did not leave his words, but after his tenure, he was able to notice the current situation of corrupt city defense and a shortage of military equipment. Although Song and Liao had no war at that time, he was far-sighted and thought that there was a strong enemy in the north. This was a very dangerous situation. He then improved and improved his military defense and equipment. Therefore, he is very talented in the military field.

Which affects Chen yaozhi's loyal return to the country not only because of the ethos of the society in which he worships the document, but also because of the fact that he uses archery as a "skill of husband.

Song youkang su lost half of the wall while Qin had no sword skill and unified the world! I don't know how to use it. I don't know how to use it. Just like the one who has learned the things of the Dragon killing, what is the use of its technology?

Essence of tools

What makes the Qin State really powerful is not a tool or technique, but a method of commercialization that started in the middle of the Warring States Period in the last three hundred years.

One of the methods of Shang Yi's changes is war-related: abolishing the title system, and granting the title by military power. In addition, it is implicitly related to the subsequent war, that is, "allow people to land reclamation, and allow them to freely buy and sell land. Tax is borne on average based on the amount of land occupied by each person ". These two changes directly led to the "farming war" policy that later forced Qin. That is to say, "farming and fighting" means "farming and raising" means "farming and fighting. Qin first occupied shuguo (now in Sichuan), and then used Li bingxing to repair water conservancy, which led to unprecedented civil prosperity for farmers, businesses, and weaving in shuguo. Nearly 60 years after the destruction of Shu, Qin destroyed Chu in one fell swoop, and then unified the six countries to settle the world.

But what does this have to do with software engineering? Or what is the relationship with the nature of the tool?

Let's take a look at the differences between ouyeko's sword and Qin's weapons. Only by casting the sword for the whole life of ouyeezi has five handles for the king of Yue and three handles for the King of Chu. Qin did not pursue this kind of sword-making art, but used the outdated materials at that time (the end of the Warring States period. However, the production process is very mature. It is said that the length, hardness and toughness, and the ratio of copper to Tin are almost perfect. However, on the other main weapon "crossbows", Qin appeared to be "skilled": the crossbows, components, and arrows have reached a very standardized production level, and the components of the crossbows can be exchanged, the mean error of the bottom side width of the arrow is only plus or minus 0.83mm. In the same period, Mrs. Xu, the famous lady of Zhao Guo, made a (TIE) sword with a value of gold. The sword of yanxi, South Korea, also had more than 10 secrets.

Qin did not look at the material of the heavy sword, as well as the complicated and artistic method of making the sword. Qin pays attention to the length characteristics of the sword, the maturity of the bronze technology, and the "componentization" of the crossbows. In essence, it is based on their understanding of the "global war: what is the benefit of war if it is just a favorite plaything, not a weapon that most people can get?

Let's take a look at the difference between the swordsman and Qin's tactics. The technology of the daughter-in-the-air did not discuss where the sword stabbed, where the sword went, and no moves. It was a theory or idea. Qin's rule of war is simple and quick, that is: rapid attack, a sword stabbed the enemy, and the first to enter.

Once the use of tools increases to the "skill" and methodology "level, it is difficult to understand and master. If it takes decades for the soldiers to understand the sword, the country will be destroyed before it is realized. Therefore, Qin did not focus on techniques like "dancing seven swords at the same time", but on the ability to quickly kill the enemy with a sword tip. It is indeed a veteran of the Qin Dynasty. I know that practical techniques are the same, and that Tao Chuan Yi is the one that cannot be generalized.

Just like engineering and programming, it is only possible to focus On Exquisite techniques and pursue details and branches. But for engineering, practical techniques that allow teams to understand, implement, and quickly and effectively are what they really need. Like a war, the advantages and disadvantages of techniques are not critical in a team-based project. The key lies in whether a certain technique can bring overall results to the team, not whether a person prefers it or is familiar with it. Like Chen kangsu Gong, there is no second technology in the world, and it is useless to use it for "group battles.

The Qin State regards war as a project of hundreds of years. Therefore, it does not only focus on tools and techniques. In fact, Qin is a typical country that manages the country by law. Therefore, all war-related activities, such as how military orders are communicated (the Military symbol system) and how the military sources are supplemented (Military Service System) how morale is motivated (Military Merit Jue system), how logistic support (farming war system), and so on can all be implemented and tested in accordance with laws and regulations, in this way, the whole team (Army) of the project is widely used.

Among them, weapons are just a tool for battles and play a very important role in Qin Jun. However, Qin is not superstitious about weapons, but uses them as tools, analyzes the nature of weapons such as swords and crossbows, and understands the causes and functions of specific characteristics, and then standardize the methods and technologies (rather than techniques and techniques ). These constitute the military Foundation of the Qin army and constitute part of the great project of war.

The essence of tools for engineering is to focus on and make full use of the features that are beneficial to the overall project. How can one person and one skill and one thing be the essentials of engineering? Therefore, we finally see that none of the six countries that have the best weapon and skill are there, and only one strong Qin has unified the world.

Weishoushener

Many experts do not understand the essence of the tool. He writes programs faster, but only remembers that he has read and written more code than others. He thinks more carefully than others, but he has made more mistakes than others; he can lead the project team only because he has experienced many project teams.

Such a person can be a competent person. But it may not be true or knowledgeable.

We can see that the oil seller sold oil all his life and had to use four words, "hand-cooked ". If a person's experience and technology reaches the "hand-cooked" level, then there will be no progress.

Chen yaozhi's so-called high points are just like the oil seller's skills. How much oil may the oil supplier sell when they raise the spoon higher? Chen yaoxun has farther down the Arrow Target tree, and may have killed another Hu weier?

The deeper the technique, the more likely it will be to forget the original goal and application of this technique-just as Chen yaoxun only regards archery as a skill and cannot see its nature as a battlefield weapon; it is also like the oil seller blindly rehearsing techniques, rather than considering the purpose of selling oil, and the techniques are only superficial. Fortunately, the oil seller was able to realize his magical skills, but he was familiar with it. Nowadays, many experts and skilled players are still playing tricks and skills?

"Allan dare to light my shot !" When I talk about specific tools such as the Rational Unified Process and the UML (Unified Modeling Language), these tools are just the end of the project, many people are angry to say, what is similar to what Chen yaozhi said at that time?
