Download Yii2 (1) and record Yii2 using the learning records of yii2 at night I have previously learned about Yii1. although I am not familiar with Yii1, I understand the structure slightly. Now I want to learn how to use Yii2 at night and plan to build a background management system. here I will reco

specification to make a good look. Then, it is a painful rewrite. Different organizations in different companies have different coding specifications, which have no advantages or disadvantages. They cannot be mixed with various specifications. This is really not a standard. In addition, it should not be too rigid and can be flexibly simplified. I see this: front-end encoding Specification Zhihu's naming rules are like this: zu-top-nav-link, that is, [namespace-module-content]. Ensure that the f

functions you have. 2. Find out the technologies required to implement these functions. 3. The entire software function is subdivided, followed by step subdivision modules. 4. Code each module that implements each function provides interfaces for debugging. 5. Integrate the access function module and complete debugging. The sophomore dog did not intend to summarize the methods when doing things by himself, so he should use them with caution. MOOC

java program execution process. Source file --> compiler --> byter code --> jvm. First, you need to write the source file, compile it, compile the bytecode file, and finally send it to the java Virtual Machine to execute the bytecode file. This is the process of generating the java program. Don't talk about the preparation knowledge. You can go to MOOC to learn. Enter the topic below, write a classic program, and output hello world, hahaha. Suppose

Decision trees (decision tree), Pocket (Bagging), Adaptive Enhancement (AdaBoost) When the bagging and AdaBoost algorithms are reclassified, it is time for all weak classifiers to function simultaneously. The difference between them is whether each weak separator has the same weight as the subsequent blending generation G. Decision Tree is a conditional fusion algorithm that all

Summary of Python Installation Problems and python Problems Today is the first time I came into contact with the Python tool. I wrote a video on MOOC and installed and used it. The instructor on the video did not elaborate on how to install and use Python, but briefly introduced some common Python tools. Then I directly talked about installing the request library. I thought that the request can be directly installed without additional software insta

rate (perimeter, Area) twice, but because the custom constant is used, the literal constant 3.1415926 is written only once. This avoids errors caused by repeated writing. Running effect: Note: constants are assigned values during declaration and cannot be modified later. The above is taken from MOOC course C # getting started with development Using constants seems to allow you to set the role identity in the game, for example: 1 namespace Test

left to right (the assignment operator is opposite ). See the following code: bool b = 20 - (15 - 8) * 2 > 10 (2 % 2 * 2 + 2) > 2;Console.WriteLine(b); Analysis: first, calculate the brackets with the highest priority. (15-8) get 7. (2% 2*2 + 2) Calculate % and * first, and then calculate +, if the result is 2, the expression is changed: bool b=20-7*2>102>2; Next, the highest priority is 7*2, followed by subtraction, and changed: bool b=6>102>2; Continue to calculate the two greater than sign

See the following example: Int x = 5; x + = 2; // This sentence is equivalent to x = x + 2. After execution, the value of x is 7. Minus value "-= ":First subtract and then assign a value. See the following example: Int x = 5; x-= 2; // This sentence is equivalent to x = X-2;

Top three output test scores for Java programming exercises When I was studying MOOC, I encountered such a Java programming exercise. I checked the Basic Java knowledge I learned: Compile a Java program based on your knowledge to achieve the top three requirements for output test scores: 1. the test scores are saved in the array scores, with the array elements 89,-23, 64, 91,119, 52,732 require that you use a custom method to rank the score and output
