Introduction to Cisco Port Channel)Port trunking is used to bind multiple low-bandwidth ports of a vswitch to a high-bandwidth link to achieve load balancing. Avoid link congestion. Through configuration, You can bind two or four ports to forward data on specific ports to prevent packet loss when the forwarding rate of a single link is too low. Advantages of Trunking: The price is low, and the performance is close to that of Gigabit Ethernet. You do n

Introduction to Visual channelsThe core content of data visualization is visual coding, which is the technique of mapping data information into visual elements. Visual coding consists of two parts: a geometric marker (
This tutorial mainly uses Photoshop to use the channel method to skin a freckled woman, and the channel grinding is now the mainstream grinding method, accurate, fast and very popular. Here is a more difficult example of what the whole process of skin grinding. The material picture is a bit dark and partial color, before grinding, we need to have a simple color. Then use the
the other threads do what things, the program automatically exits. Then we think of a way to add a sleep function, so that the main function waits for the Goroutine function to complete before exiting.
The changed code is as follows:
123456789101112131415
Package mainimport ("FMT""Time")funcmain() {go goroutine () time. Sleep (3 * time. Second)}funcgoroutine() {fmt. Println ("Goroutine")}
As expected, the program successfully print
A picture of RGB mode, is the red, blue, green three primary colors on three different channels, each channel is the same color, but the brightness is different, and each of the channels are gray images; we are using the contrast of channel brightness to buckle the picture. This is called the channel cutout. In the channel
CMYK to multiple channels
Multi-channel patterns are usually present as intermediate transition modes for channel splitting and merging. In the opening section of this chapter, the reader has rehearsed the different effects of the channels under different combinations of rules (RGB, Lab, or CMYK).
A much larger use of multichannel mode is in printing. If you convert a CMYK-mode image to multichannel mode,

Starting from this blog post, we began to analyze the source code of the Muduo network library, mainly combining the "Linux multi-thread Server programming" and some learning materials on the Internet!

There are indications that 3G is bound to become the only way to upgrade China's mobile communication industry. In order to preserve and increase the value of the industry's state-owned assets, 3G licenses will also be issued to existing fixed network operators, to become a full-telecom service operator. In the name of the investor, the country intends to build 3 to 3 in the near future ~ Four world-class telecom operation giants, which means more intense market competition in the 3G era is comi
using Photoshop to pull the map, both convenient and good effect. Here I'm going to write a concise tutorial on how to figure out the sample shots, and also want to help someone like the need for hair-gouging.
1, the use of the channel mask in this example method used to deal with portrait of slender hair and animal hair, the effect is extremely powerful. In fact, there are many ways to pull the map (this is Photoshop flexible, powerful performance)
We know that almost all the colours seen by the eye are made of three primary colors of optics: red, green, Blue (RGB) composition, and the computer wants to express 16581375 colors, it will not be silly to use the definition of 16581375 colors to express, as with nature, summed up the most basic three primary colors: R, G, B, You can determine the color of a pixel by just giving the ratio of three colors. What are the benefits of doing this? Obviously, since every color is calculated, we can ch

Two or more programs are in the same state of the computer system as they were between the beginning and the end. This is called a multi-channel program design.

Introduction
Essentially, WCF is a communication service framework that allows us to use different transmission protocols and different message encoding formats to interact with different WS-* series standards, all these details are handled by the channel stack. In the WCF topic series (8): Deep Channel Programming Model Part 1-design, I have a deep understanding of the
When using WCF for communication, the communication policy is changed by configuring binding. Without binding configuration, you can also use the built-in binding encapsulation of WCF.To implement a basic communication similar to socket, so that you can understand the implementation policy of WCF:Listener:
Uri Address = New Uri ( "Http: // MAID: 8888/baseservice" ); Basichttpbinding Binding = New Basichttpbinding (); // Use the httpbinding integrated by WCF Ichannellistener Ireplychannel

Io is the process of copying data from the primary storage and external devices (hard disks, terminals, and networks. Io is the underlying function implementation of the operating system, which is completed by I/O commands.
The system provides advanced tools for executing I/O in all languages. In Java programming, standard lower version I/O uses a stream to complete I/O operations. All I/O operations are considered as a single byte flow, an object called Stream moves one byte a
1. What is a channel?Channel, also known as Channel or frequency band, is a data signal transmission channel that uses wireless signals as the transmission carrier.The operating frequency of the 2.4G band is 2.4-2.4835 GHz. The 83.5MHz band is divided into 13 channels. The center frequency of each
The Channel Mixer command may be the least common command in all palette commands in PS, because it is complex, intuitive, and involves a lot of theoretical knowledge, which is daunting to many beginners. However, once you can master it skillfully, you can get through the joints between color, channel, mask and so on to deepen the understanding and application of PS. This time, about the
