Here's how: To capture the entire desktop, press command-shift-3. The screen shot is automatically saved as a PNG file on your desktop.To copy the entire desktop, press command-control-shift-3. The screen shot'll be placed on your clipboard for your paste into another program. To capture a portion of the desktop, press command-shift-4. A cross-hair cursor would appear and you can click and drag to select t
Shell scripting is an essential skill for Linux OPS engineers and a very important skill, so it's only good to learn shell programming well. Basic grammar I will not speak, learn the C language of these languages, a little bit to understand the basis of shell programming, so we directly cut to the point.The 20th day of the classes:Today's Course Outline:
Functions in Shell programming
Write a script that automatically mounts
How to implement automatic mount with AutoFS

,www,inw and so on, as long as it is composed of these 3 characters, multiple characters are matched successfully.
How does the above match to, each one has 2 results? This is the child pattern (a child match), by default, in addition to combining multiple characters into a whole, and storing the parentheses, the part of the expression enclosed in a temporary buffer for subsequent regular expression calls. In this example above, we do not need to call later. So how do you block out this subexpr
Talk about JavaScript events, event bubbling, event capture, and blocking default events These three topics, whether in the interview or in peacetime work, are difficult to avoid.
Event Capture Phase: an event is searched down from the top level of the tag until the event target (target) is captured.
Event bubbling phase: The event starts at the event target and bubbles up until the top level of the page ta
This article mainly introduces the usage of the smarty built-in function capture, and analyzes the three common usage of the capture. if you need it, refer to the example in this article to describe the usage of the smarty built-in function capture. Share it with you for your reference. The specific analysis is as follows:

I. Job Requirements
1. Job content: develop a program to capture data on the smart phone network. The system is not limited, and there are no restrictions on objects (WiFi, Bluetooth, GPRS, etc ).
2. Organizational Form: The team members can be divided into groups. The group consists of up to three members with a clear division of labor. The group leader should be designated.
3. Submit jobs: source code, documents (electronic and printed), and demos.
Okay, I won't let your asynchronous port smoke. I am not saying that nmcap must be simple and easy to use. In fact, it is not difficult to use. however, any command line tool has its shortcomings. isn't the GUI invented to make up for this deficiency?
Nmcap makes automatic crawling easier. also, it allows you to provide scripts to others, which is easier than teaching a person how to use them. I don't know how many people have tried to instruct their parents, friends, or customers by phone
Tcpdump helps us capture and save network packages. the saved network packages can be used to analyze network load conditions. The packages can be parsed using the tcpdump command, or saved as files suffixed with pcap, use wireshark and other software for viewing. The following nine examples of using tcpdump are provided to illustrate the specific use of tcpdump. 1. packet capture for specific network ports
Some of the most recent difficulties in learning JavaScript, such as bubbling and capturing, have been mentioned many times, but I don't know where to apply it. Found some good Article FAQ, here to share with you.
Event bubbling and event capture were presented by Microsoft and Netscape, both of which were designed to address the issue of the event flow (sequence of events) in the page.

Author: Ma JinhuWe have learned how Visual Basic, Delphi, and other languages can capture screen images. So how does C # implement this function? This article will discuss this issue.I. programming and development and running environment:(1). Microsoft Windows 2000 Server Edition(2). Net FrameWork SDK Beta 2II. Key Steps of program design and specific implementation methods:(1) first create a Bitmap object with the same size as the current screen:To i
The so-called multimedia computers usually have sound cards (soft or hard sound cards), which can capture audio. You must be familiar with the attachment "recorder" program that comes with windows. You can use a microphone for recording and generate a wave file. After reading this article, you will find that using DirectShow to write an audio capture application is also so easy!
As you know, DirectShow sup

You can enter the keyword Wireshark, usage, and tutorial on Baidu to find a lot of related materials. So the question is, Why should I write this series of articles?
Most of the materials you can find earlier may have two minor problems:

Oh, look also carefully, yes, we can not worry about it, and someone asked, you did not write about the delegation of the detailed introduction, oh, it seems that my fans know a lot, but this introduction focus on different, nonsense less, into the theme is the truth.The delegate of c#1.0We know it today. A list can be implemented by lamda such as where or predicate, whereas in c#1.0 we have to write a method to implement the predicate logi
