A problem found:The server is a Linux system, with JMeter test interface, found to open a lot of TCP connections, [[email protected] bin]# ulimit-n 65535 with this command set the total number of connections, when the pressure test, the number of connections may reach more than 50000, Easily error-prone; View the number of TCP in each state:Netstat-an | awk '/^tc

* Returns the number of 1 in a binary representation of a number. *#include This is the most easy way to think of, and constantly in addition to 2 modulo 2 to take the remainder, the following gives another method (omit part of the statement)... i = 32;while (i--) {if (num 1 = = 1) count++; num = num>>1;}This method is shifted to the right, so that the lowest bits 1 are judged, and a more efficient method

In a Cartesian coordinate system, draw a segment from (0,0) to (n,m) to find the number of integer points covered by the segment in a Cartesian coordinate system, from (0,0) to (n,m) draw a line segment, such as n=6,m=4: The line segment in the diagram covers the 3 hour, respectively (0,0) (3,2) (6,4). Similarly, if the n=m=3 line is covered with 4 whole point (0,0) (2,2) (3,3) now gives N and M, the number

Method One:Only the thumbnails are loaded when the picture is loaded from the network or locally.This method does not occupy a lot of memory, but its fatal disadvantage is that because the load is thumbnail, so the picture distortion is more serious, for the image quality requirements of high application, you can use the following method.Method Two:The use of Java Soft reference, image caching, will often need to load the picture, stored in the cache, to avoid repeated loading.Method Three:Destr

When you deploy an MVC project, you are likely to be prompted with the following scenarios:SYSTEM.WEB.MVC, version=3.0.0.1, culture=neutral, Publickeytoken=31bf3856ad364e35 ' which has a higher Version than Referenced assembly ' SYSTEM.WEB.MVC, version=3.0.0.0, Culture=neutral, publickeytoken=31bf3856ad364e35The analysis is due to the Mvc.dll version number of the machine and the server inconsistency, there are two ways to resolve.The first type: the

/IP designer was originally designed to do so there are two main reasons 1. Prevent packets from the last connection, re-appear after getting lost, affect new connections (after 2MSL, all duplicates in the last connection will disappear) 2. A reliable shutdown of the TCP connection the last ACK (FIN) sent at the active shutdown, which is likely to be lost, then the passive side will resend fin, and if the active side is in the CLOSED state, it will respond to RST instead of ACK. So the active
