Angular users want to know how data binding works. You may see a variety of words: $ watch, $ apply, and $ digest. How do they work? Here I want to answer these questions. In fact, they have already been answered in the official documents, but I still want to combine them.

Subject:
Write an Android Application to access an HTTP-based data service system. To improve security, the data service system adopts the HTTP digest authentication system. The reason is that compared with the basic authentication method, digest authentication ensures the transmission security of authentication information (user name and password) and is easier to use than SSL. A user name and password dia
The HMAC (hash message authentication code) hashes the authorization code, which encrypts the message digest using a key based on the Message digest algorithm (for example, the Md5,sha Series algorithm). It is equivalent to a vest, inside can use MD5,SHA1, SHA256,SHA384,SHA512 and other message digest algorithms, based on the generated message
This is a technique used in conjunction with message authentication codes to ensure message integrity. The main use of one-way hash function algorithm, can be used to verify the integrity of the message, and by hashing the password directly in the form of text preservation, etc., the current widely used algorithms have MD4, MD5, sha-1,jdk1.5 to support the above, the message digest in Java is very simple, Java.security.MessageDigest provides an easy w

Introduction
I mentioned in cocos2d-x study note 16: record storage 1: CCUserDefault all kinds of defects of CCUserDefalut archiving, one of which is plaintext storage, players can directly modify the archive.
This article describes how to use the Digest algorithm for archive verification.

This article is primarily geared towards those who are just beginning to learn angularjs and want to understand how data binding (data-binding) works,If you are already familiar with how to use ANGULARJS, I strongly advise you not to read it.Angularjs users want to know how data-binding works, they encounter a lot of terminology.such as $wacth, $apply, $digest, dirty-checking (dirty value detection) ... Wait, what are they doing?In this article I will
MySQL Performance Profiling Tool (pt-query-digest) is also from percona-toolkit

Troubleshooting of abnormal shutdown of MySQL Slave (pt-slave-restart)
Including
1. slow log (default)
2. tcpdump
3. general log
4. binlog
5. show processlist
The experiment simulates a certain amount of pressure through tpcc, and enables binlog, general log, slow log, and tcpdump to collect logs.
1. slow log method

Example of the message digest algorithm implemented by Python and GO, pythongo
Common message digest algorithms include MD5 and SHA. These algorithms are available in the python and go libraries and can be called as needed. Here we will summarize the implementation of python and go.

Briefly:Message-digest algorithm 5 (Information-Digest algorithm). Often said "MD5 encryption", is it → information-digest algorithm.MD5, in fact, is an algorithm. You can put a string, or a file, or a compressed package, after executing MD5, you can generate a fixed length of 128bit string. This string is basically the only one.Irreversibility:Everyone has a dif
