Base64 principle Base64 is a method of representing arbitrary binary data with 64 characters. For binary data, a group of three bytes is encoded as four bytes, that is, 3 × 8bit=4 × 6bit. As shown in the figure below, the three consecutive bytes (8bit) are divided into four 6bits, and then each 6bit high two bits ...

1. overview In order to ensure the data's concealment and security, we often save some password data stored in the database by encryption, among which MD5 is a common encryption method 2. Encryption method I know that there are two ways to achieve encryption 1. Encrypt before data insertion 2. Encrypt when inserting data ...

In recent period of time, we have wandered back and forth between image algorithm and audio algorithm. There are often some requirements for audio sampling and transcoding. Existing well-known open source libraries, such as webrtc, Sox, etc, Code reading is really disturbing. And audio resampling is actually interpolation algorithm. It is not m ...

Premise: when you go to the toilet, there is only one pit, and someone takes it IO: synchronous blocking (waiting at the door of the toilet, doing nothing, waiting for the person to come out) NIO: synchronous non blocking (take a cigarette out of the door and go in every now and then to see if the person is out) AIO: asynchronous non blocking ( ...
