Strings type
The string type is binary secure.
Redis strings can contain any data, such as jpg images or serialized objects. From the perspective of internal implementation, the string can be regarded as a byte array, and the maximum value is 1 GB.Struct sdshdr {Long len; // The length of the bufLong free; // number of available bytes of the bufChar buf []; // actual string content};

Andrew Tridgell kept silence on the criticism of Linus Torvalds while seeking expert legal advice. At this time, another open-source community leader, Bruce Perens, was unable to withstand the attack. He publicly defended the work of The Tridgell reverse engineering Bitkeeper (BK) protocol.
Earlier, Torvalds criticized Tridgell's behavior and posted two harsh comments on the Internet. In the second petition, Torvalds even used the word "vicious destructive behavior.Perens says it's time Torvald

1. Array typeECMAScript arrays and arrays in other languages are sequential tables, but have the following characteristics:A. Each item can hold any type of data.B. The size of the array can be dynamically adjusted.C. Length property of the array: readable writable, you can remove an item from the end of the array by setting the value of length or add a new item to the array 1) Create method 1. Use the array constructor var arr = new Array (); var arr = new Array (;)//pre-specified array

different ways. As long as you don't negate the boss's point of view, you can let the boss put down the resistance, so as to be able to change their ideas in a more secure way. My mother, a good teacher and principal, once told me, "leave the children with a way out--so they can do the right thing." "The same applies to executives," he said.In the following ways, you can rationally and safely help your boss see other ideas:1. "Yes, but ..."-Philippe Wilson worked as head of human resources at S

This article aims to introduce a priceless resource, Larry Wall's patch program, to Linux beginners. Patch is an interface for finding differences between files using the GNU diff command. diff has many options, but this command is most commonly used to generate a file, this file lists the rows in which the content has changed.

What is Perl?
Perl is a high-level programming language, written by Larry Wall and many others, and incorporates the characteristics of many languages. It is mainly by the ubiquitous C language, followed by the SED, Awk,unix shell and at least a dozen other tools and languages evolved. Perl for process, files, and text has a very strong processing and transformation capabilities, so all the tasks related to rapid prototyping design, system tools, sof

In an interview with Han Bing, the "nets" who leak personal information of citizens are not only the interests of citizens, but also the reputation and economic interests of enterprises and institutions. If the circumstances are more serious, the credibility, public trust, and reputation of enterprises and institutions will drop to the bottom, resulting in some practical benefits. We can also i
According to a report released today by the ponemon Institute, most companies are actively moving towards cloud computing, even in the absence of effective security protection, transfers confidential or sensitive data to the cloud.The report pointed out that the transfer speed of enterprises to cloud computing far exceeds the carrying capacity of the enterprise's cloud security environment. According to the survey, most respondents said they had uploa
other MVC frameworks that are designed to have the controller responsible for changing the data. But Backbone's design idea is that the controller's role is only to handle user requests from the view layer, as well as access to the corresponding model layer. The model layer itself is responsible for obtaining data from the data source, as well as for data encapsulation.The following example illustrates how the data model is declared and initialized in backbone.Stooge = Backbone.Model.extend ({
Often see the configuration file contains some similar format variable names and values, in fact, is a serialization process, when you need to use these databases will be a deserialization process, is to restore the string to his original data structure. Here's how PHP does serialization and deserialization of data.In fact, PHP uses two functions,serialize and Unserialize, to serialize and deserialize data.Serialize format an array into an ordered stringunserialize to restore an array to a grou
