Net by default uses the reflection technology to obtain all member variable values for comparison, which is extremely inefficient. If the equals method of the value object we write is used (for example, placing the value object in hashtable), The equals method should be overloaded.

The problem with preventing SQL injection in these details is that those who are careless programmers or novice programmers, because they do not have the data submitted by the user to do some necessary filtering, resulting in a test for everyone to the time of the breach of your database, Let's briefly introduce a SQL injection method that may occur when a user logs on without security configuration, let's take a look below. For example, the followin

First you have to think, who is your target customer base? For example, you choose the emotional aspects of the article as a breach of your site, no problem, maybe your site traffic in a short time is really big, the reader is also more, but if you look carefully, your target customer base is not the

Mysqld is the MySQL server-side main process, and it can be said that Mysqld is the true core of MySQL, all work revolves around the mysqld process. So to dissect MySQL this behemoth, Mysqld's code is the best breach. Everything starts with the familiar main () function, actually starting with the Mysqld_main () function. These codes are in mysqld.cc. Mysqld_main () then called the Win_main) (). The Win_main () function mainly does some initializati

the release date, after you each loan repayment day is this day. Among them, if your first loan occurs on the day of 29, 30, 31st of the month, the repayment date will be uniform for each month 21st. 2) The first repayment date of a loan other than that of the first one will span the most recent repayment date (including the same day). For example, your current repayment date is 21st every month, and when you borrow again on January 15, the first installment of your loan is

If you want to be a dedicated talent, select the project manager. Another important difference between a project manager and a product manager is that the scope of authorization is different: A project manager is generally the person in charge of an authorized contract: A Project contract is a legal contract t

First, prefaceIn the first two cracked articles, we introduced how to use dynamic debugging to crack the APK, one is through debugging Smali source code, one is through debugging so code to carry out the tracing of the crack, then today we on the two article crack method, Take a look at how to develop an application in Android, how to do a layer of security protection of our application, of course, most of the applications in the market now have done some protection strategy, but there is no abs

, and with it, the browser does not go directly to the Web server to retrieve the Web page but makes a request to the proxy server, which is sent to the proxy server first. The proxy server retrieves the information needed by the browser and transmits it to your browser.Moreover, most proxy servers have the function of buffering, like a large cache, it has a lot of storage space, it constantly store the new data to its native storage, if the browser requested data on its native memory already ex

use the R-series commands to access remote computers and Exchange files on the network. Using the R-Series commands requires special attention, because if the user is not careful, it can cause a serious security breach. After the user issues an R-series command, the remote system checks the file named/etc/hosts.equiv to see if the user's host is listed in the file. If it does not find the user's host, check the remote machine with the same name as th

time, it is thought that the sample application may have done a service-side data validation, the following to see how to solve this problem, the breach of the problem is relatively simple, do not use the hint string information to find, because this error message may be returned by the service, this time need to grab a packet, each request, Just grab a service pack and use the Fiddler tool here:See here, the parameters of the request is very simple,

For better collaboration, code provided by the standard library or by a third party must adhere to common dependency guidelines.For example, it is necessary to abide by hashCode equals the common conventions and to ensure that a series of collection classes and other classes of usage and methods in the Java collect

of TechnologyWell, here we are, the process of the tool: first go to the server to get the configuration information, then decrypt the JSON format into the map structure, and then parse some of the fields, such as the validity period and the number of days to save the information to local. If the discovery expires, you cannot use the tool directly. And we will find the breach is his log loopholes, so in the development process must remember the progr

because the current full-screen mobile phone almost only in industrial design, but not in depth experience and application of deep cultivation, it does not provide consumers with "hardware + software" combined into a deep experience. So if you just put a nice, full screen on your smartphone, but don't give your smartphone a better inner experience, this "full screen" phone is simply a hardware upgrade and doesn't have the revolutionary elements that affect and disrupt the next phone process.Bey

A hashing algorithm in bitcoin implementationIt can be said that the entire implementation of Bitcoin is based on the existing and even many years of computer science in the field of technology or concepts of integration, hashing algorithm in the Bitcoin application is almost all aspects, mainly including SHA256 and RIPEMD160, Bitcoin combines the application of these two hashing algorithms into two functions: hash256 (d) =sha256 (sha256 (d)) and hash160 (d) =ripemd160 (sha256 (d)), where D is t
