Recently, the company's network is always slow. When I was so upset, I came up with a small tool for online monitoring and latency testing. In fact, both 360 and Jinshan have corresponding functions. However, I am a code engineer. I am not used to the commercial atmosphere of 360, and Kingsoft is not angry. Let's take a look at Kingsoft. Pretty good. Below is an example Look, this MS is really inferior to my home Alas... The results a

This is a type of question that maximizes the minimum value. This type of question is typically answered using a bipartite enumeration. In the case of a binary answer, first determine the exact range of the answer. Then, the key is how to judge the answer line for each enumeration. I use the [I] array to indicate the height of the flowers in the initial phase. B [I] indicates how much the flowers will increase to reach the answer of the current enumeration (that is, the value of the MID. The two

In unity3d, the object. Destroy () method will destroy the passed parameter object, which will cause all references to this object to become null afterwards. However, this method is not executed immediately when it is called. In each frame, all calls to the destroy () method are delayed until all updates () of the current frame () after the call ends (before the real rendering), it is executed in a unified manner. The result is that the object is still available in the same method after destroy

: Fastclick.jsWhy is there a delay?From clicking on the element on the screen to the click event that triggered the element, the mobile browser will have a waiting time of about 300 milliseconds. Why is it so designed? Because it wants to see if you're going to double-click (double tap) operation.1. Introduction of Fastclick.js File1 typesrc= ' fastclick.js '>script > 2.

First you need to know why the click on the mobile side is dull?Google's developer document 300MS tap delay, gone away can find the reasonThe mobile side to determine is not a double-click, so after clicking can not immediately fire click, to wait 300ms, until the confirmation is not double-click to trigger click. So it causes the click to have a delay. Method 1meta name= "viewport" content="Width=device-width" > is to set the viewport to the actual pixel of the device, there will be no 300ms

When we use IE8 in Windows XP, when browsing a Web page in one window and discovering that there are multiple Iexplore.exe processes in Task Manager, and that the process is not automatically closed after the tab is closed, the process is stubbornly occupied with system resource failures (as shown in the following illustration). This is not really a fault or something, but a new feature of IE8. IE8 designed a backup iexplore.exe process so that the Browsing tab crashes without causing other tabs

You can see the obvious volatility of the data. 3 Analog network packet loss:# TC Qdisc Add dev eth0 root netem loss 1% This command sets the transmission of the ETH0 network card to a random drop of 1% packets.
