know as little as possible about other objects.Basic idea: reduce coupling.g: the principle of synthetic multiplexingInstead of using inheritance, it is preferable to use a combination rather than an inheritance principle, which is to use the composition/aggregation method first.Basic idea: In taking advantage of the object's lowest point, the combination is preferred, not the inheritance, because any changes to the parent class can directly affect the behavior of the subclass.eg. To pack an el

are too stupid, maybe everyone is right, I really not this piece of material. The more a person wants to get angry, maybe it was a bit crazy at that time? I do not know where to Xiehuo, I pulled the drawer of the desk beside me, and slammed it on the ground, and I sat on the ground, and then a strange voice came out of my butt: like a flush toilet. I was so scared that I jumped again. Another look, the original is the father to the United States brought back a gadget, is the United States

Unconsciously this semester has come to an end, in the people can not help but feel some sigh for the time of the rapid passage of time, but also quietly change everything. In general, this semester is better than the previous semester in terms of time management, and of course there are many flaws. In English alone, in the time management industry to do better than before, but the most important thing is, first of all, there must be an attitude, only the correct mentality, will have a harvest.

, whether the network of friends to interpret the brand, to give you a good feeling how many? Again such as marketing personnel's dress and conversation, in the user's eyes, to a certain extent, also indirectly experience their products, at least, wearing slippers marketing, will not give people a good feeling. Edge experience, as important. 3. The Intangible Experience There are two kinds of intangible experience, one is the use of a user, experience the product after the word of mouth sprea

. We call it a "similar" relationship; the new type has an interface of the old type, but it also contains other functions, so it cannot be said that they are completely equivalent. For example, let's consider the condition of the refrigerator. Suppose our rooms are equipped with a variety of controllers for refrigeration, that is, we have the necessary "interface" to control refrigeration. Now assuming the machine is out of service, we replace it wit

Label: Variable attribute requirements: We need to store a lot of appliances in the database, such as TV, refrigerator and so on. Typically, in a program, our class diagram is: Eva Design One way to do this kind of inherited mutable property is to create another table that stores properties as rows. 　　 The data stored here looks like this: 　　 Such a design is called: The entity-genus-value, abbreviation: EVA, or also called open architecture, no mode.

improve the internal quality of the system. This is the value of system refactoring. The following important question is which areas need to be refactored? There is the code for the foul-smelling lane (badsmell) . What's a smelly smell? Imagine you open the refrigerator door, come out a stink way you know there is something rotten in the refrigerator, to clear. The code smells the same way:The first thing

of (Response)----Loop 2, long poll.Long poll in fact, the principle of Ajax polling is similar, is the use of polling, but to take a blocking model (always call, do not receive the phone), that is, after the client initiates the connection, if there is no message, it has not returned response to the client. Until a message is returned, the client establishes a connection again and again after the return is completed.The scenario is as follows:Client: La La la, there is no new information, no wo

the meaning of words. For example, enrichment can be interpreted as "sufficient, not empty ".6. Metaphorical Display MethodIt is difficult to reveal abstract concepts that are hard to be interpreted in a specific language by analogy. For example:Bloodbath-like a bloodbath, it describes the brutal slaughter of people.7. Integrated Analysis MethodIn some words, the relationship between the meaning of the phoneme and the meaning of the word is obvious. You can analyze the meaning of the phoneme fi

structure: Product level structure refers to the inheritance structure of products. for example, an abstract class is a TV set. its sub-classes include Haier TV sets, Hisense TV sets, and tcl TV sets, abstract TV sets and TV sets of a specific brand constitute a product level structure. abstract TV sets are the parent class, while TV sets of a specific brand are the child classes. Product Family:In the abstract factory model, a product family refers to a group of products produced by the same

important files after the system is crashed and reinstalled. But let's go back and think about it. Did we go wrong from the very beginning? If the program is placed in the/Application directory to keep the files in good order, and the movie is placed in ~ /Movie directory, music in ~ /Music directory. Put the document in ~ /Document directory, isn't it neat? Why is the system file reinstalled lost? Isn't it because of a problem with the operating system design? Continue to the next stage. Why s

now I am turning back to the opposite. 　　3. Pre-partitioning of the first hard drive (or new computer) Like everyone else, my previous PC also has a partition, a C-drive system, and D-drive software. The e-drive is the installer and iso, and a f-drive video music, the G disk is a document and work file. It seems well-organized and does not worry about the loss of important files after the system is crashed and reinstalled. But let's go back and think about it. Did we go wrong from the very begi

floppy disk, this part is useless, the default values of kernel startup options generated during compilation are stored. The 512 * n Bytes starting from 512 bytes are called the setup part, which is the real mode part of the Linux kernel and runs in the real mode, the main function is to prepare an environment for Linux kernel startup in protected mode. This part will switch to the protection mode and jump to the kernel execution in the protection mode. The last part is the kernel of the protec

First, Curl Summary Individual will summarize curl request into three steps 1. Create a curl handle (curl_init) and set the parameters (curl_setopt) (Open the refrigerator) 2, execute the request (CURL_EXEC), processing the returned data (put the elephant in) 3. Turn off Curl (curl_close) and release all resources (close the refrigerator) In fact, if the code looks more complex, the complex place may be th

The first part: Apple theoryEarly in the morning to open the refrigerator ready to take out the milk to eat breakfast, suddenly found that the refrigerator has accumulated four bottles of fresh milk, which does not include the room outside the milk box today's new two bottles. How to solve? This reminds me of the famous Apple theory, which has similar problems. Bought a bag of apples, a few days later, some
