JFinal wave in the sum of my talk I talked about the relationship between mathematics and software for some of the views of Bowen's review JFinal Marketing. In this article I will explain in detail my understanding.
Throughout the accumulation of human knowledge, can be roughly divided into "Road" and "skill". The so-called "Road", that is Heaven, which is the law of nature. The "technique", that technology is the application of human has been found that the laws of nature. Qin Chinese culture that is self-fall from the sky and light weight Road surgery, which of course has its historical limitations, but the road in the first surgery is beyond doubt.
Wave total cited in JFinal 4.8 Euler's identity in the press release:
In my opinion Euler's identity belongs to the category of "Road", it is simple and beautiful expression of the relationship between several basic amount, which is the natural law of our universe, was discovered, not invented.
I always reply to the wave of talked about:
Just because the relationship is very universal elements + factor modeling good use, it will be like you said a lot of things and there is isomorphic. The key here, the difficulty is: what will you extract and abstract elements and relationships become, a hundred individuals can have one hundred kinds of extraction methods. Master of mathematics Euler extracted e, i, pi, 0,1, +, = five elements and two relationships, I ask why not another ordinary extracted, because of this extraction process is extremely difficult, extremely difficult, need the essence of profound insight. The first step to extract abstract elements and the relationship just modeling, you have to verify the relationship between the elements and the logic is not self-consistent, continuous contact, contact him, or you build this model is wrong. This step alone is very difficult to do. Well, the next step is the number of elements, the relationship is minimized, which means you can not delete any of the elements or from the relationship you build the model, otherwise the model is wrong, this can not continue to reach or deleting elements of the relationship jfinal called minimalist state. Jfinal corresponds to the top-level design is the five elements Handler, Interceptor, Controller, Render, Plugin, not be able to delete any of them, or else a lot of features not realize. Do you think philosophy is metaphysics, but this is my day. You do not have this way of thinking, does not mean others have is wrong, you have your own way of thinking, perhaps others are not quite agree
I think this analogy is not appropriate Euler equation is an expression of the natural law, the truth is to be found; while you can not put JFinal design due to the scope of the laws of nature and of truth, it is being designed and developed out, and not be found. the five elements mentioned therein also completely unjustified and several mathematical constants Euler equation par. I basically can be sure Euler's identity development and design of the process of discovery and JFinal no comparable Euler did not like the wave will always just mentioned, e, i, pi, 0,1, +, = two five elements into a relationship with the extracted identity. Euler's identity Euler in the special case of the formula x = pi time, and Euler's formula is complex analysis of human achievement in the field of mathematics, in addition to its discovery Euler also contribute to other mathematicians.
On the other hand, the total wave mentioned JFinal five elements Handler, Interceptor, Controller, Render, Plugin, these concepts should have appeared long before JFinal. PlayFrameowrk1.x in 2009, when he had the same concept to construction, and I know Play did not start out that way is, first of Play is based on the Servlet architecture, just as the evolution of the original architecture in later iterations. the total wave let me also comment in " talk actframework in the design of the top-level architecture way of thinking used . "this is a big problem, it may require additional open pit discussion. but here I can definitely say that I did not have done any top-level architecture design. I also do not believe that the school belongs to the so-called architect for me, a good structure is evolved, not designed.
