Netcat or NC is one of the Linux tools for debugging and checking the Network toolkit. Can be used to create TCP/IP connections, and the biggest use is to handle TCP/UDP sockets.Here we will use some examples to learn the Netcat command.1. Using Netcat on the server-client architectureThe Netcat tool can run in server mode and listen on a specified port? 1 $ nc-l 2389 You can then use client mode to connect to port 2389

This article summarizes the PHP Chinese string interception method, very practical skills. The specific methods are analyzed as follows:1, the use of mbstring Extension Library MB_SUBSTR interception will not appear garbled.2, write the interception function, but the efficiency is not as high as the Mbstring expansion library.3, if only for the output interception of the string, can be implemented as follows: substr ($STR, 0,). chr (0).SUBSTR () function can split the text, but the text to be di

be a constant, but you can use a variable in an expression in the constructor method.Common methods for regular expressions:1. RegExp object's Test (string to be examined) method, how to conform to the rule return true, otherwise return false;2. The search (reg) method of the string object to find if the string contains a string that matches the rule3. Replace (reg) method of a String object, replacing the string in the string that matches the rule4. The Split (reg) method of the string object,

request, optional State: Typically randomly generated to identify the client's current status, and the authentication server returns the value as it is. Use the JS Ajax interceptor to get token and refresh token examples for the front and back end of the project to separate the authorization.Auth.jsConst Full_charter = ' abcdefghijklmnopqrstuvwxyzabcdefghijklmnopgrstuvwxyz '; Const Oauth_server= ' Http://localhost:9000/server '; Const Redire

Parsing XML data with JavaScript is a common programming task that JavaScript can do, and jquery can certainly do. Let's summarize some examples of using jquery to parse XML.The first scenario: Yanshi The second scenario: The general steps are as follows:1. Read the XML file$.get ("XMLFile.xml", function (XML) {//xml is the content that can be read, read see 2nd});2. Reading XML contentIf the read XML is coming from an XML file, this is combined

(deprecate). Java recommends providing information in Javadoc to inform the user why this method has been deprecated and what the workaround is.3. @SuppressWarnings – This note simply informs the compiler that ignoring them produces a special warning, such as the use of primitive types in Java generics. Its persistence strategy (retention policy) is source and will be discarded in the compiler.Let's look at an example that shows how to use built-in annotations, as well as the custom annotations

The figure is the inventor of the RSA public key algorithm, from left to right Ron Rivest, Adi Shamir, Leonard Adleman. Photo taken in 1978RSA encryption algorithm is the most commonly used asymmetric encryption algorithm, CFCA in the certificate service cannot leave it. But a lot of new colleagues don't know much about it, just see a book in which the author uses examples to describe it in a simplified and vivid way, so that advanced mathematical the

The examples in this article describe the common operations of databases in Android. Share to everyone for your reference, specific as follows: Android database operation is very common, we will often use, the operation of the method also has a variety of forms, here I have the most common form of the two forms of record, for later use for easy to view. I don't write annotations and explanations, because the Android database operation is essentially

The implementation of this effect is key to the use of date objects and settimeout. A total of three examples, HTML structure as follows, do not add CSS style. Main experience of JavaScript implementation Window.onload=function () { var P1=document.getelementbyid ("P1"), P2=document.getelementbyid ("P2"); P3=document.getelementbyid ("P3"); Showtime1 (); Showtime2 (); Showtime3 (); } 1. Simple implementation

Append: Represents the value corresponding to the key and adds the input at the end Delete: Remove Key's corresponding value More protocols can be consulted: the Protocol.txt in the memcached package Specific examples are as follows: It is important to note that if you specify a character length of 5 at set time and the input exceeds this length, you will be given an error: Client_error bad data chunk 4. Write code to memcached data access op

Preface If you want to use less code to achieve a Cool Data tab, Echarts is a way to implement it. The official website provides a lot of examples for reference: http://echarts.baidu.com/examples.html. Interest can be a glimpse of the first quick ... Environment Construction This environment builds so easy! In fact, there is only one echarts.min.js. Http://echarts.baidu.com/download.html can be downloaded from the website.

Previously seen in Osso many such examples, the various methods are complex, please see the following examples to implement graphics counters. Use in Web pages please use ?A text file that holds the count$count = "Count.txt";Number of digits of the counter, if not filled, the default is 6-bit$wei = "";The URL path of the image$tu = "/tcount/images";?>?if ($wei = = "") {$wei = 6;}if (!file_exists ($count))

time, that is, if notify ()/ Notifyall () is followed by code, and will continue, knowing that the current thread is finished before releasing the synchronized lock object; 3.notify ()/notifyall () after execution, if the right has a sleep () method, will cause the current thread into the blocking state, but the synchronization object lock is not released, still keep their own, then will continue to execute this thread, next to the same 2; 4.wait ()/notify ()/nitifyall () the communication or

This paper describes the use of Optionparser module in Python in detail, and it has good reference value for studying python in depth. Share for everyone to use for reference. The specific analysis is as follows: In general, there are two built-in modules in Python that handle command-line arguments: One is getopt, "Deep in Python" also mentions that only simple processing of command-line parameters; The other is Optparse, which is powerful and easy to use, and makes it easy to generate stand

Thinkphp Framework is a very popular and widely used PHP framework in China, we take a deep look at some simple development examples to explore the development convenience of this framework, as well as the ease of expansion of the design. At the same time from the source analysis point of view of the framework of some deficiencies, as far as possible to do a comprehensive and objective evaluation. This assumes that you have used the thinkphp framework

thread of a process finishes running and the child thread is still executing, the process will not exit until all child threads are finished. For example, the following examples: Copy Code code as follows: Import threading, Time Class Mythread (threading. Thread): def __init__ (self, threadname = ""): #threading. Thread.__init__ (self, name = ThreadName) Super (Mythread, self). __init__ (name = ThreadName) def run (self): Pr

Using foreach Smarty, and then use the Smarty Loop foreach to do a nested loop instance. Two methods are very simple, the key is to construct a multidimensional array, and then loop the corresponding key name to reference ... is not very vague, see examples bar, bad analysis, examples intuitive good-looking, first look at the array, quoting the original article: code is as follows copy

30 great Pull-down menus and sliding menu design examples are worth the reference. Whenever I do a website for a client, I have to toss the best display of level two navigation in a horizontal menu (and don't make it look like it was 10 years ago), and then I started looking for some inspiration. I've found a lot of websites that use pull-down menus or sliding menus, and I think you might be interested in the exam
