As we all know, the copy provided by Microsoft's operating system is "mentally retarded" with low speed and no resumable data transfer. In addition, copying will drag other applications down and occupy a large amount of File Cache. Therefore, many advanced copy tools are born, and FastCopy is the best. The copy speed of FastCopy can basically reach the limit of the disk, and its implementation can be seen because it is open-source. However, it is a pity that his project is VC6, and the source co

Who is the fastest? Horizontal evaluation of four browsers at home and abroad (1) In recent months, the competition in the browser industry has been fierce. The three major domestic dual-core browsers have successively released the latest version. The cheetah browser 5.0 focuses on saving the province and speeding up the Internet by 50%. sogou high-speed browser 5.0 joins the smart prefetch engine. The 360 security browser also released the latest

Scenario Description: This articleOnly verifies the parsing speed of using Json Key as the deserialization condition in Android Environment. The conclusion is that the fastest resolution speed is not Alibaba's fastjson, nor Google's Gson, but json-smart. Android 4.4.2 Fastjson-1.1.34.android.jar Gson-2.2.4.jar Json-smart-2.0-RC3.jar ** Note the limitations of the scenario ** Core code: package com.h3c.mytestview;import java.io.StringReader;import net

Recently, I made a small program that assigned values to attributes of the parent class to the attributes of the subclass. I used the automapper component. It feels good. I want to explore its principle and try it by myself. To implement this function, first retrieve the attributes of the parent class object through reflection, and then set the attributes with the same name as the subclass object. However, when we think about the reflection efficiency, we plan to use another method. After search

The fastest way to share directories under Linux is Chszs, without the permission of bloggers to reprint. Permission to reprint should be marked by the author and blog home: Http://blog.csdn.net/chszsBuild FTP, or build network File system, these methods can realize the directory sharing of Linux. But both the FTP and the network file system are too powerful, so they have some inconvenient places. For example, do you want to quickly share a directory

resource while other processes are accessing the resource. Therefore, it is primarily used as a means of synchronization between processes and between different threads within the same process.6. Signal (sinal): signal is a more complex mode of communication for notifying the receiving process that an event has occurred.7. Shared Memory: Shared memory is the mapping of memory that can be accessed by other processes, which is created by a process, but can be accessed by multiple processes. share

In order to turn the wall convenient, bought a VPN, go to OS X below the official did not provide the right client, can not choose the fastest line. So he wrote a script, manually ping the fastest IP. The code is as follows Copy Code $servers = Array (Array (' VIP Dutch line ', ' nl01.yyuu.me ', ' 81.4.105.195 ', ' 4122 or 3108 '),Array (' VIP French Line ', ' fr01.yyuu.me ', ' 1

April 14, 2016, Aliyun's Debian source hangs. The Aliyun host system that caused WENWU cannot update, and the Web service software cannot be installed. So I tried to modify the Sources.list file. The following is a summary of Wenwu, using the Apt-spy command, to automatically find and update the fastest source of Debian software. First: Install Apt-spy, command as follows: Apt-get Install Apt-spy Second: Move and back up the oldest sources.list fil

JSON has become a recognized standard for data transfer between the current server and the Web application, but just as many of the things we are accustomed to, you will feel that it is taken for granted that you do not think deeply. We rarely think about how these JSON libraries are different, but in fact they are really not the same. Therefore, we ran a benchmark to test several commonly used JSON libraries to see which library was the fastest when

program and test, I finally wrote the Web database paging method that I think is the fastest in theory. Second: The specific implementation of the stored procedures. We'll talk about this approach in conjunction with a BBS question. How to make a BBS every page only realistic need one page record? And what do we need to provide the database with those parameters? The following parameters may be available. The first: is the number of pages we need to

Today, in the 51js forum, a netizen published a fast sorting algorithm implemented by ctipt PT, which also involved the data sorting application in javasctipt in the previous days. In order to increase the sorting speed, it uses a fast sorting algorithm. But What surprised me was that, one of the following netizens replied that the sort method of Array itself in javascript was the fastest, faster than the fast sorting algorithm. At that time, I was ve

IBMRoadrunner, the world's fastest computer with Linux installed (figure)-Linux Enterprise Application-Linux server application information. See the following for details. It's so powerful. The operating system uses Red Hat Enterprise Linux and covers an area of 1,100 m² square meters. Maybe you will ask Linux like this? You are really right. Linux is the boss in this scale. The IDC is as long as 3/4 football fields. Use Infiniband for network conne

It is inconvenient to operate shell on a virtual machine. simply make the virtual machine a server and use putty to connect it...
