Switch faults are still quite common. So I have studied the switch fault types and analysis methods, and I will share them with you here, hoping they will be useful to you. Failure during switch operation is inevitable. However, it is the duty of maintenance personnel to promptly handle the fault, identify the fault point as soon as possible, and eliminate the fault. To do this, you must understand the type of switch faults and have the ability to ana

Why analyze algorithmic performance?Should take care of many important things, such as user-friendliness, modularity, safety, maintainability, etc. Why worry about performance?The answer to this is simple, only we have performance, can have all of the above things.For example, if we behave like money, we can buy all the above things. Another reason to study the show is that-speed is fun! Given the algorithms for both tasks, how do we find out which one is better?usually for us, a naïve ("tunnel

First, static analysis of the basic technology1, you can calculate the malicious program MD5 value by using software, and then retrieve the MD5 value to obtain information and use as a label "Md5deep winmd5"2, by retrieving the malicious code string to obtain the corresponding function call interpretation, functional behavior and module invocation. When the retrievable string is very young, it is possible to shell, (note "LoadLibrary" and "GetProcAddr

principal component Analysis ( Principal Component Analysis , PCA is a multivariate statistical analysis method that transforms multiple variables through a linear transformation to select fewer important variables. principle: When we use the statistical analysis method to study the multi-variable problem, the number o

Article Description: Apsalar: Pay attention to user behavior analysis to make money. In the past, terminology such as group research and funnel analysis was used only in medical statistics and hard core sales companies. Now these terms, along with other jargon (such as K-Factor and whale), are being used in the mobile gaming industry. "It's a very competitive market," he said. What you need is

1. Necessity of log Analysis The development of the Internet, will generate a large number of web logs or mobile logs, the log contains a very rich variety of user information. Mining this kind of information through analytic analysis will produce corresponding data value. General medium-sized Web sites (10w + PV), will generate more than 1G of web logs per day. Large Web sites or very large URLs may produ

1, structured analysis methodThe structure method is mainly used to analyze the function of the system, and it is a kind of analytic method that divides the function level directly according to the data stream; The basic feature of structured methods is to use graphical symbols whenever possible when expressing problems, even if non-computer professionals are also easy to understand, design data flow chart only consider the basic functions that the sy

Yii Source Analysis (-), Yii source analysis As the first show of source analysis, I chose Yii (read as crooked rather than crooked Love), its praise of the word I will not say, directly into the subject. Prepare the material first, we recommend to download the latest version of Yii source package (1.1.15) from official website. In demos there is one of the simp

A brief analysis of the steps of FEM analysis after UG modeling. Many netizens who are learning UG This software have been discussing a problem recently, that is: UG how to carry on finite element analysis. To solve this problem, we need to first understand what is UG finite element analysis. And online on the UG finit

This analysis is mainly on the source code analysis, divided into two pieces 1. Xposedinstall Reverse Analysis Java code, 2. Analyze the principle of app_process and frame hooks replaced by frames.The first part:Mainly hope that the analysis is as thorough as possible, this is the second

C program compilation process analysis, compilation AnalysisA few days ago, I read chapter 2 "Compilation and link" in "Programmer self-cultivation-linking, loading and library". I will summarize the C program compilation process based on the content. I usually use gcc now, so it is natural to use GCC to compile hellworld as an example. A brief summary is as follows. The source code of hello. c is as follows: /* He asked hovertree.com */int main () {p

Therefore, the menu creation function is called for the menu creation function of abstractgalleryactivity. public class AbstractGalleryActivity extends Activity implements GalleryContext { private static final String TAG = "Abstract

The process-oriented design method emphasizes the consideration of the software's functional characteristics. process-oriented designers usually divide the system into multiple functional modules at different levels, at the same time, try to minimize the Coupling Degree between modules. The main task of object-oriented analysis is to establish an accurate, complete, and consistent system model-analysis

As a software developer, every time the demand analysis ends, we will sigh, how is this requirement completely different from the same as above? As a customer, we can't understand what the difference is between 1-2-3 and 4-4? I think the first problem is that the customer's requirement is to solve the business problem. In the big aspect, the assumption is divided into 1-2-3-4, this is generally okay. If a problem occurs, the customer can agree to ma
