Miscellaneous about thinking in solving problems (thinking, analogy, and heuristic) By Liu weipeng (pongba) C ++'s Luo Yun (http://blog.csdn.net/pongba) Toplanguage (http://groups.google.com/group/pongba) The topic on toplanguage has been discussed for a while, with many gains. The purpose of our discussion is not to solve the problem, but to reflect on the general and cross-problem thinking rules in the process of solving the problem. Simply resolv

thinkphp Auth Authentication analogy RBAC Better authorization authentication method (Auth class authentication) Auth class has been in the thinkphp code warehouse for a long time, but because there has been no tutorial, few people know it, it is actually more convenient than RBAC.RBAC is based on the node authentication, if you want to control more than the node finer permissions is a bit difficult, such as the action button on the page, I want to de

point where you have no controversy: the life tension of a website comes from its original content. From the beginning of this first source, 兙 began to gradually deduce the process of analogy. Original content is not everyone evenly divided into the level of things, which must exist pros and cons of the true and false points. This process has reminded 兙 of the history of our great Communist Party of China throughout the new democratic revolution peri

First, imitation techniques:In the process of invention innovation, imitation is a very natural thinking and thinking. Although people have wisdom, but in many ways compared with other organisms, the ability of the person itself is relatively low. For other organisms to evolve through the natural selection of the advantages, as intelligent human beings, for granted should learn and use, imitation is the first step. Of course, in addition to imitating natural things or phenomena, can also imitate

On the Internet to see the synchronous asynchronous interpretation, feel very image, reproduced come to remember.The difference between synchronous and asynchronousFor example: Ordinary B/s mode (synchronous) Ajax Technology (asynchronous)Synchronization: Submit request, wait for server processing, processing completed returns this period the client browser cannot do anythingAsynchronous: Requests are processed through event triggering server processing (which is still something the browser can

The analogy between JSON and XML(1). Advantages and disadvantages of XMLA. Uniform format, in line with the standards;B. Easy to interact with other systems remotely, data sharing is more convenient.A.xml file is large, the file format is complex, the transmission occupies the bandwidth;B. Both the server side and the client need to spend a lot of code to parse the XML, causing the server and client code to become unusually complex and difficult to ma

article in the result set, but, because the first group and then by the publication time descending order, which led to the first by the classification number in ascending order, on this basis and then by time descending, This results in the latest published articles not necessarily appearing on the homepage. It seems that the problem is not as simple as thought.WorkaroundAfter a day of hard searching and several attempts, finally found a solution, the following SQL statement can be used to sen

long as the isolation can be, if the toilet, bathtub, wash table are separated relatively independent, in fact, the bathroom can be used at the same time for three people,Of course, three people do not do the same thing. This will refine the lock granularity, you can just close the bathroom door when you are in the shower, others may still go in to wash their hands. If the toilet was designed without dividing different functional areasCan not achieve the maximum use of toilet resources.This is

Do migrant workers know this as a metaphor? ProgramThe workers are migrant workers. It is nice to say that they are construction workers. What does the civil society rely on to survive? I'm afraid it's a craft. It's also a migrant labor. Some people will use electric welding, while others will only move bricks. In an inappropriate analogy, computer languages are like welding and bricks. The ultimate goal is to build a building. Case1If you find th

How to make clothes to wash more clean, people according to the clothing material, size and other characteristics, the invention of washing powder detergent and other tools. By different indicators to determine that the clothes are really more effective wash clean. and so wash the clothes of the leader of the wife to check, if the hand wash clothes did not wash clean or wash too s

I do not like the "code Nong" "Code Workers" "Program ape" This kind of demeaning words. My grandfather is a tailor, in my memory he relies on the home to make clothes for others to earn a living, is a craftsman. My career has been dealing with code, making a living by writing code, and being a craftsman. Of course, a good workman should be able to call it a code craftsman. I like to refer to this group of code craftsmen as software designers. Why software designers, not software engineers, co

led to a small problem. This is the "game running small Problem" and "the RPM package required to install Oracle " Both, feel there is some kind of analogy, although the game with the technical analogy is a bit far-fetched, but I think the "dependency" of the truth is still interlinked. The is then combined to address fifa14 the process of the problem, re-smoothing the oracle installation in the Span s
