First, the concept of entropy coding:The bigger the entropy, the more chaotic.Entropy in Informatics:
Used to measure the entropy of messages, and the uncertainty of information
The more random and irrelevant information, the higher the entropy
Source code theorem:
This shows the relationship between the entropy of Shannon and the probability of the source sign.
Entropy of information is the lower limit of average code length after lossless

The basic method of entropy coding in the first and H:
Entropy coding has the function of eliminating statistical redundancy between data, and the syntax element is written to the output code stream as the last operation in the coded end.
Entropy decoding, as the first step in decoding process, parses the code stream into grammatical elements for sub

The following articles mainly introduce the basic tutorial of SQL coding optimization for the IBM DB2 database. The importance of such a specific query is that the more important the query is, you may need to optimize indexes by creating indexes. If you are coding the query that the CIO is running every day, make sure it provides the best performance.

FIG-PHPPSR specification series 1-basic code specification 1. Introduction to FIG-PHP and PSR
The FIG-PHP has developed a series of PHP Development specifications, called the PSR, which is short for the Framework Interoperability Group, which is short for PHP Standard Recommendation. The FIG-PHP working group initially originated from the project representative's discussion of the commonalities between the two projects and found a way to work together
At this point, you should have completed the following preparations:
1. Install JDK
2. Install the SDK (and update the relevant version in the Manager)
3. Related IDE (such as eclipse)
4. After installing ADT
5. Install AVD (if you simulate a real machine)
The setup of the preliminary environment is basically complete, and the HelloWorld can be run according to the online tutorial to ensure that the process can go through.
