Ascii Character Encoding

Base64 is one of the most commonly used encodings, such as the development of passing parameters, the <img/> tags in modern browsers to render pictures directly through Base64 strings, and for messages and so on.　　The BASE64 encoding is defined in RFC2045, which is defined as: Base64 content transfer encoding is designed to describe the 8-bit byte of any sequence as a form that is not easily recognized directly by the person.

MSSQL Chinese character processing (character set encoding and collation) SQL Server processing of character set encoding and sorting rules is a very tangled problem.

The basic constituent unit of Chinese text is Chinese characters. At present, the total number of Chinese characters has more than 60,000 words. The characteristics of large number of Chinese characters, complicated shape, variant and many other characters give a series of problems to the representation, processing, transmission, exchange, input and output of Chinese characters in the computer, and also bring a lot of difficulty to character work. There are several coding schemes for Chinese character coding: 1. Gb2312-80 Code &http://www.aliyun.com/zixun/aggregation ...

1. Boxing, unpacking or aliases many of the introduction of C #. NET learning experience books on the introduction of the int-> Int32 is a boxing process, the reverse is the process of unpacking. This is true of many other variable types, such as short <-> int16,long <->int64. For the average programmer, it is not necessary to understand this process, because these boxes and unboxing actions can be automatically completed, do not need to write code to intervene. But we need to remember that ...

Hadoop serialization and Writable Interface (i) introduced the Hadoop serialization, the Hadoop writable interface and how to customize your own writable class, and in this article we continue to introduce the Hadoop writable class, 　　This time we are concerned about the length of bytes occupied after the writable instance was serialized, and the composition of the sequence of bytes after the writable instance was serialized. Why to consider the byte length of the writable class large data program ...
