I. Introduction of the topicIn the large nine lattice of 9x9, there are 9 small nine gongge of 3x3 lattice, and provide a certain number of numbers. Based on these numbers, use logic and reasoning to fill the other blanks with numbers from 1 to 9. Each number can only appear once per Gongne, and each number can appear only once per row or column. This kind of game only needs the logical thinking ability, has nothing to do with the numerical operation. Although the play is simple, but the digital

Google C + + Style Guide is not an encyclopedia, nor is it a C + + usage guideline, but it describes the coding guidelines for Google and its open source projects, does not seek to be comprehensive and absolutely correct, and many people doubt some of its rules. But as one of the most influential coding specifications, it has a lot of content worth studying.The following is mainly from GSG, director of Titus Winters in the Cppcon 2014 speech.The purpo

In the front-end development process, we often need to change the this point, usually we think of the call method, but for the understanding of call many people are not very clear, then the following small mention Mo will give you a detailed talk about calls and apply the detailed knowledge.The first parameter of call is passed to the object, and the parameter can be any type (including null). Example: Call (OBJ,ARG1,ARG2,ARG3) apply the first parameter to the object, the argument can be an arra

Underscore.js has a sortby function that supports arrays and objects sorted by one field:
The code is as follows
Copy Code
var ret = _.sortby ([5, 2, 3, 4, 1],function (num) {return num;}); >> [1, 2, 3, 4, 5]
However, if you want to display in reverse order, Underscore.js still does not have the transparent support reverse operation. You can actually borrow the elements you want to sort by taking a negative

PCI (here, PCI-DSS, payment card Industry data security standards), We call this a hybrid implementation pattern. The solution is to use a combination of virtual LANs, firewalls, intrusion detection/intrusion prevention systems (IDS/IPS) to ensure virtual machine isolation to support hybrid implementation patterns. Data classification and policy-based management, such as DLP data breach protection, can also be used to prevent data clutter. In a cloud

A dedicated firewall like the Web application Firewall (WAF) is very promising. Web application firewalls can ensure that web-based malware does not set foot in your business. It can also prevent hackers from exploiting vulnerabilities into the 7th layer of OSI, which in turn prevents further intrusion. With the increasing trend of web appli
