about the historical evolution of the code, UTF-8 is how to develop, why Windows still keep GBK encoding ...
And so on, online a search a lot of, most of them are forwarded, share after the same content, still can not solve my inner doubts ...
Coding is a matter of egg pain, if not clear, how to mix in China?
I have set a basic world view of coding by looking through multiple documents and in-depth
average bit number of information contained by all symbols of the source.
Source Coding should minimize the redundancy of the source to bring it closer to entropy.
Transmit more source information with fewer bits
Entropy Coding: minimizes the entropy of a message based on the probability model of the message source in data compression.
Lossless Compression
Variable-Length Encoding
Information Interchange, American Information Interchange standard codes) is a computer coding system based on the Roman alphabet.
2. Features
It is mainly used to display modern English and other Western European languages. It is the most common single byte coding system today and is equivalent to ISO 646.
3. Include content
Control characters: Enter, backspace, newline keys, and so on.

If you want to be an excellent programmer, good code is important, how can you write good code? In this article we will give you some PHP coding specifications and recommendations.

PHP code files must start with the
PHP code files must be encoded with UTF-8 without a BOM.
Example sublime, setting increased, "show_encoding": True

Character Set and character encodingThe information stored in the computer is represented by a binary number, and the characters we see on the screen, such as English and kanji, are the result of binar

Entropy coding is the encoding process by entropy principle without losing any information. Entropy is the average amount of information (measurement of uncertainty) of the source. Common entropy codes are: Shannon (Shannon) encoding, Huffman (Huffman) encoding and arithmetic coding (arithmetic coding). In video coding

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

But I try to be easy to write and I hope to be useful to other friends. Af
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
The G optical transmission technology based on digital coherent receiving PM-QPSK modulation has a milestone in the long-distance optical transmission technology history. The error correction coding technology can be used to further improve the system performance when modulation, detection, balancing, and multiplexing cannot meet the system transmission performance requirements. To achieve the current transmission error rate of 10 Gb OOK on the existi

2. Midi, short for Musical Instrument Digital Interface, is also known as the digital interface of musical instruments. It is a unified international standard for digital music/electronic synthesis instruments. It defines how computer music programs, digital synthesizer, and other electronic devices exchange Music signals, it specifies the protocol for data transmission between cables and hardware and equipment connected by different manufacturers of electronic instruments and computers, and
For programming languages, a good coding style can not only generate effective framework encoding at the beginning of programming, but also make our coding clearer and more standardized. However, as mentioned by the author in this article, although the coding style of some Java programs is widely used, it will have a negative impact on the maintainability of

This problem is also due to their own inconvenience, usually the code is managed to GitHub or coding, on the one hand, for the convenience of code management, and then better storage code.
But recently it's a problem. After the local code commits git, it is cumbersome to go to the server to perform the following git pull.
So you want to use GitHub or coding's Webhook to automate code deployment.
Simply say the whole process-When you push the code to a
