In the classroom of Political Science in middle school, dialectical materialism tells us that everything includes two aspects of opposition and unity. To faithfully reflect the true nature of a transaction, we must adhere to the Contradiction Analysis Method of split into two parts, and make a comprehensive analysis of the contradiction, we must use a two-point theory to understand the nature of the transaction. Simply put, everything needs to see its good and bad sides.

Since the title of front-end engineers, the development of front-end is changing with each passing day. Compared with other mature fields, although the front-end
Code review is a process by which code quality is improved by reviewing codes, which occupies an extremely important position in the XP method, and has become an indispensable part of software engineering. This paper discusses some concepts and experiences of code review, and puts forward some suggestions on how to pay attention to the code review and Code review. Most of the issues covered in this article
talk about what is intra-frame prediction and inter-frame prediction in the encoding process before understanding I-frame B-frame P-frames 1. Intra-frame predictive coding
Intra-frame encoding is used to reduce spatial redundancy of images. In order to improve the efficiency of intra-frame
the design must be damaged to adapt to the impact. This usually leads to the "arbitrary coding" that managers think, but this is the reality of software development.
For example, in A project I recently worked on, I found A time series dependency between the internal structure of module A and Module B. Worse, the internal structure of module A is hidden behind a

into a relatively simple small cycle, through positive communication, feedback and a number of other methods, developers and customers can be very clear development progress, changes, pending problems and potential difficulties, etc. and adjust the development process in time according to the actual situation.

trace code. You can easily remove aspects from the build configuration. Keep track of the code wherever you need it, even if you add new methods to the target class. This can eliminate human error. At the same time you know that all the tracking code is deleted and you don't ignore anything when you remove from the build configuration. You have a reusable aspect that can be applied and upgraded.
contract design or defensive programming

Simply put, why do you need to encode? For example, our computer needs to represent letters ' a ', ' B ', and so on, but how are these letters represented in the computer's memory? It is well known that in computer memory data is represented in binary notation, so we need to convert these letters and numbers or symbols that need to be represented into binary representations that can be represented on the co
and write, and a real database. When it first ran up, little printf was very excited. However, this procedure is not good enough.This program requires refactoring, better testing, documentation, and analysis. It only ran for a while before it crashed. Then again and again the crash!The setup of the program is wrong, the log does not work, the disk speed is unsta
What is an efficient software? An efficient software should not only run faster than software that implements the same functionality, but it should also consume less system resources. This article brings together some of the experiences that the author has accumulated while using VB for software development, and shows you how to write efficient VB code with some simple examples. It contains some techniques
multi-threading features, to use multi-threaded tasks I still prefer to use java/c++ static type language.2, "For example, do not distinguish between byte stream, multibyte string, Unicode string, you need to write in PHP file Unicode, Utf-8, GBK strings must all be escaped with 16, this is a kind of what a crash experience." A few of the disgusting ones with Python not coded disaster? I don't have to worr

The extreme programming team always keeps the system integrated and running at all times. Programmers write all product code in pairs and work together for all time. They are encoded in a similar way to ensure that all Members can understand and improve all the code as needed.Core pr
In the programmer I usually see, if the pure coding ability to see, personally think can be divided into five categories, in order: 1. Copy TypeCopy-type players are legendary "code-copy", they have little idea of the implementation of the function, the thing is to copy the fragments from the code written by the Internet or other team members, and then put in the project, if the running project has expecte

This article describes the key to the duplication in C ++-pointer type and two meaningful concepts-static and dynamic.

As mentioned above, the memory is accessed through variables in C ++, but according to the previous instructions, C ++ can only use variables to operate the memory, that is

Recently, many people invited me to answer a variety of Java EE development of the primary issues, I do not have to emphasize that the beginning of the basic knowledge of beginners to a solid, what is the basic knowledge of Java? What is the basic knowledge of Java? The question is
What is h264 video file format?
H.264 is the latest format defined by the MPEG-4 standard, and it is also one of the most technically available video coding formats, representing the latest technology, some also called AVC (Advanced Video
Multi-channel lpcm: the original format of lossless audio tracks. It is equivalent to a wave file and does not require decoding. You can directly input a Power Amplifier for DA conversion. The fiber optic and coaxial interfaces can only transmit two-channel lpcm, multi-channel lpcm requires HDMI interface transmission. PCM: nonlinear pulse Coding Modulation
