Have you ever met such a site? ArticleThe system uses the HTML file generated statically by FSO to display the file. This can reduce the server load and increase the access speed. Second, it also stops SQLInjection attacks. Let me talk about their article system principle: all the articles are inDatabaseThere is a copy. In addition, an HTML page is generated based on the template. Attack method: Check the source file/check whether there is a page called through Js. For example, call to update t

submitted thrift as an Open-source project to the Apache Foundation. For Facebook at the time, the creation of thrift was designed to address the large data transmission between the various systems of Facebook and the cross-platform nature of the system, so thrift could support a variety of programming languages, such as C + +, C #, Cocoa, Erlang , Haskell, Java, Ocami, Perl, PHP, Python, Ruby, and Smalltalk. communication between many different languages, thrift can be used as a high-performa

to use thrift Thrift defines it fairly succinctly, so that our use of the process is also exceptionally convenient, in simple terms, the use of thrift process only requires the following four steps:1. Design the data format (struct, enum, etc.) that requires interaction and specific services (service), define the Thrift interface description file, that is, the suffix name is. Thrift2. Using the Thrift tool (I am using the older version of 0.5.0), generate the target language file based on the p

use an intermediate language (IDL, Interface Definition language) to define RPC interfaces and data types, and then use a compiler to generate different language code (such as C + +, Java, Python), and the generated code is responsible for RPC protocol layer and Transport layer implementation. For example, the implementation of a service is in C + +, the server needs to generate C + + code to implement the RPC protocol and Transport layer, the servic

The Savgol function returns the coefficients of a savitzky-golay smoothing filter, which can then be applied using the CON VOL function. The Savitzky-golay smoothing filter, also known as least squares or DISPO (digital smoothing polynomial), can be used to s Mooth a noisy signal. The filter is defined as a weighted moving average with weighting given as a polynomial of a certain degree. The returned coefficients, when applied to a signal, perform a polynomial least-squares fit within the filter

the prototype chain of another object.For differences between the two methods, see JavaScript isPrototypeOf vs instanceof usage. Only use prototype chain for inheritance Disadvantages: 1. The prototype property of the reference type value will be shared by the instance; 2. When creating a child-type instance, parameters cannot be passed to the super-Type constructor. functionFather(){this.name ="father";this.friends = ['aaa','bbb'];}functionSon(){}So
