of the numbers in the decimal group inside the three-dimensional array, the three-dimensional inside of which there are three arrays, which requires the sum of the array count in the three second-dimension, and I foreach out and then + = Is the three-dimensional array inside all the count is added, I now do not need to ask for all and, need to separate and, to help in the following to solve the way, thank you! I don't know if I have a clear statement

Before I mistook the high concurrency solution is a thread or queue can be resolved, because high concurrency is a lot of users in the access, resulting in incorrect system data, loss of data phenomenon, so think of the queue to solve, in fact, the way the queue solution can also be handled, such as we are in the auction of goods, Forward comments microblogging or seconds to kill the goods, etc., the same time the traffic is particularly large, the qu

Engineers have a natural instinct for solving problems, especially the bugs of his system. So as long as there is a problem, he wants to solve them all, it seems that as long as the more problems can be solved, he can create more value. Such logic in the enterprise software development, maintenance, may be right, but to get inside the consumer market, but almost the most important reason to kill entrepreneurs.The value of the problemBy definition, the

An engineer is naturally fond of solving problems, especially the bugs in his system. As long as a problem occurs, he wants to solve it. It seems that the more problems he can solve, the more value he can create. Such logic may be right in the development and maintenance of software for enterprises, but it is almost the most important reason to kill entrepreneurs in the consumer market. 　　Value of the probl

First, verify that the server hardware is sufficient to support the current traffic. Ordinary P4 servers generally support up to 100,000 independent IPs per day, if the traffic is larger than this, Then you must first configure a higher-performance dedicated server to solve the problem , otherwise optimization will not solve the performance problem completely. Second, optimize database access. Full static a

As we all know, Mysql paging requires the use of Limit for paging. When the data size is small, the Limit performance can be imagined. For example: {code...} the preceding SQL statement has no performance problems. However, if the offset is too low, a performance bottleneck may occur. For example, {code... as we all know, Mysql uses Limit for paging. When the data volume/Page Shard is small, the Limit performance can be imagined. For example: SELECT pid,author,hash,dateline FROM posts WHERE pid

Windows has its own IE browser, which is also the first browser to be used. Many users prefer to use IE. But recently, some users have found that IE is poisoned and do not know how to solve it? So how can we solve IE browser poisoning? The following small series will bring you a solution to Windows 7 computer IE browser poisoning. Let's take a look!Specific method:Solution 1: manually

When we use the solve function of MATLAB, we often encounter this situation, that is, the equation contains some known parameters to control, but how to get the numerical solution. Examples are as follows: var1=100To solve this equation, if you write directly, var1*x^2+20*x=0 Solve (' var1*x^2+20*x=0 ', ' x ') is not able to get the correct solution. The outp

Use arrays to solve the problem (1). Use arrays to solve the problem. Arrays are extremely common in programming, and array techniques are often used in non-array scenarios. Therefore, Arrays can be used as an important training place to solve problems with data structures.I. Basic Knowledge Overview 1. Storage This is the most basic operation. An array is a set

Weibin Yao): 1. At the beginning of the request, without the session information, Jvm_route based on round robin method, sent to a tomcat above. 2. Tomcat adds the session information and returns it to the customer. 3. When the user requests this, Jvm_route sees the name of the backend server in the session, and it transfers the request to the corresponding server. Temporarily the Jvm_route module does not yet support the default fair mode. Jvm_route's working mode and fair are conflicting. For

First solve the Java thread, solve the Java threadDifferences between threads and processes:A process is essentially an execution program. Each process has its own code and data space. A process-based multitasking feature allows your computer to run two or more programs at the same time. For example, your computer can run other applications such as fetion while running QQ. In process-based multi-task proces

Use timestamps to solve browser cache problems and timestamps to solve browser cache Problems In IE or many other browsers, if each request address is the same, the browser will not connect to the server but read the cache, which is very good for many applications, it can reduce the server pressure or reduce the bandwidth usage. However, for ajax applications, many of them must maintain a connection from t
