I haven't talked to my new blog for a long time. I have been charging urgently in the last month and busy with some private affairs. However, my blog garden is still my favorite ~ I want to make statistics this time,Class Design, coding, and performance. What should your team do first? 1. First, design the architecture and consider changes, reuse and reuse as much as possible.--->Start coding again--->Fin

HEVC Video Coding FrameworkThe HEVC coding framework is similar to the H.26X standard coding framework, and is based on a mixed block model.Figure 1 HEVC Coding Framework1. First, the video encoder divides the input video image into a non-overlapping encoding unit.2. Then the predictive

Strings are the most commonly used data types in Python, and many times you use characters that do not belong to the standard ASCII character set, and the code is likely to throw Unicodedecodeerror: ' ASCII ' codec can ' t decode byte 0xc4 In position 10:ordinal not in range (128) exception. This anomaly is easy to come across in Python, especially in python2.x, a problem that puzzles beginners. However, if you understand Python Unicode and follow certain principles in

Evaluate the knowledge of some report tools on the market, many of which rely on programming to develop reports. For simple reports, some do not require programming. However, programming is required for reports that are slightly more complex. Nowadays, information systems are becoming more and more complex. They include a large number of reports. If every report and most reports require programming, the following problems may occur: It is easy to causeProgramLong business trip. Because t

This article mainly introduces four Practical PHP Chinese encoding tips, so you no longer need to worry about coding. The Chinese encoding problem in PHP programming has plagued many people. The cause of this problem is actually very simple. every country (or region) specifies the character collation set for computer information exchange, such as the expanded ASCII code of the United States, GB2312-80 of China, JIS of Japan, etc. As the basis for info

recommended that the variable declaration appear in the code before it is empty. At least one line between the four "P" in the class, and the data in it should be blank between the functions.5. CommentsAnnotations are the specific manifestation of software readability. The program annotation amount generally occupies 20% of the program code, software engineering requirements of not less than 20%. Program a

software system structure.The tighter the connection between the modules, the stronger the couplingThe module's independence is worse.The coupling between modules depends on the complexity of the interface between modules, the mode of invocation and the information transmitted. Coupling and cohesion are the two qualitative standards of module independence, when the software system is divided into modules,

Objective The LZ77 algorithm is a lossless compression algorithm, published by the Israeli Abraham Lempel in 1977. LZ77 is a typical dictionary-based compression algorithm, and many compression techniques are now based on LZ77. In view of its position in the field of data compression, this article will be combined with the image and source details of its principles. Principle Introduction: Let's start with a few professional terms. 1.lookahead buffer (do not know how to express in Chinese, tempo

ObjectiveIn one of my previous articles, I had already talked about the HDFs EC aspect (article link Hadoop 3.0 Erasure Coding Erasure code function pre-analysis), so this article is a supplement to its content. In the previous article, the main point of this paper is to explain the HDFS from the macro level. The role of the EC and the corresponding usage scenarios do not go deep into the internal related architecture design and the content of the spe

RLP coding is the main method of data serialization in the ether square. This paper introduces the main rules and principle analysis of RLP coding, RLP coding has good data processing efficiency, especially the length and type unification as the prefix, in fact RLP is a kind of structural expansion based on ASCII coding
