mux logic

I wrote a blog post a few days ago: business logic architecture model (transaction script, table module, activity record, and domain model). This article only gives a rough description of common design methods, I feel like I'm not doing anything. After several days of research and verification, there are some new understandings. Although these are four independent architecture models, they are not unrelated. Except for the table modules rarely used in

Logic: iterator label (hereinafter referred to as "this label") is a very common label in struts. Its function is to display the value in a given container object cyclically. The source code of such a commonly used tag needs to be studied. The following lists several research results: 1. The tag uses collection internally to represent the given container. All the given container objects (such as arraylist and map) will be converted into collection obj

For a long time, the difference between logic and () is not very definite. I went online today and wroteCodeThe differences are as follows for discussion. When all operands are numbers A. after bitwise AND () are performed on two numbers, the two numbers are converted to binary values, and then right-aligned (the digits are not filled with zeros, for example, the binary representation of 11 11 is, And the binary representation of 3 is 1

This is exactly the same as the logic commands of Delphi. // Logical non-not: {not 1 = 0; not 0 = 1;} var bytenum: byte; begin // assign a value of 111111b (255); reverse: ASM mov Al, 11111111b {eax contains ax; ax contains al; Al is the low eight bits of eax} Not Al {returns 11111111} mov bytenum to the 00000000 reverse, al {give the value in register Al to the variable bytenum} end; showmessage (inttostr (bytenum); {0} // assign a value of 1B

If there is a child, congenital blindness. Can this child gradually adapt to human life? Let me assume that such a person exists in reality, and he lives well. This assumption shows a logic: the lack of an information body for import and processing does not affect intelligent creation. Further, we can think that such a person is born with no touch, maintains growth through injection, cannot identify the smell, and so on all functions except hearing a

Logic: the match tag is used to handle the substring matching problem. If the specified value matches the tag, the content in the TAG body is created. This label is used in the following scenarios: Check whether the cookie with the specified name matches the value of the tag.Check whether the header with the specified name matches the value of the tag.Check whether the JSP bean with the specified name matches the value of the tag or whether the prop

The implementation of the code is simple and the thoughts behind it are complex.If the pure implementation of the Linux TCP pacing send logic-ordinary timer version of the timer_list replaced Hrtimer, will inevitably incur failure. Because in Hrtimer's function, calling a long path function such as Tcp_write_xmit is a way of doing durian in stockings. Well, in frustration I can only refer to the practice of TSQ. Old hate Heart Demon!In the TCP impleme

, close to the user's front end, the use of PHP can be faster to complete the front-end frequent and trivial updates, free to respond to changes in demand. The structural adjustment of the page, basic validation of user input, simple logic related only to user interaction, etc. are well suited to PHP development, and can even be migrated to the front-end team with template technology like Smarty. And the basic business

introduced to me, guide me how to learn. This thing I feel from the beginning, is to learn mathematics ... And I'm learning math now. He assigned me a task to understand "logical regression" within two weeks, to learn at a time outside of work. Because I ETL to go to the project on a special busy trip. Well, look at that. So the following notes were made and talked to him. Then he asked me to continue to study math. The above is I just enter the pit: Data Mining/machine learning background ...

Switch case5, for6, while7, do While Since Dijkstra's paper went to Statement considered harmful, the C language code rarely sees Goto. (gener

more effort to achieve the same level of performance and security as a Web application. Examples of rich-client technologies include the Java swing and so on.Recently, the concepts of Web applications and rich clients have been mixed to form what is known as "hybrid clients", and "hybrid clients" try to gain the benefits of both Web applications and rich clients. Some of the rich clients that are very small and use some high-level controls may be silently downloaded to the user's desktop throug

Online GamesProgramFor a while, most programmers know that "Asynchronous logic" is one of the easiest mistakes in the game logic. The potential harm caused by money farming, experience farming, getting items without money, turning off services, getting back to files, deleting accounts, etc. In fact, it is even more interesting to have such problems in the banking system :). Different teams have different

KeyDown (function (event) {switch (event.keycode) {case 37://leftbreak;case 38://upbreak;case 39:// Rightbreak;case 40://downbreak;default:break; }});After the keyboard event is captured, we need to complete the specific game logic
