When using Photoshop, we often have to "pull" out some objects with complex shapes very cleanly, for the production of synthetic images used, generally we need to enlarge the image using a lasso or a path tool manual circle, with these two tools can be made, but this is the most common method, As a master of graphics, how can you not use the channel it! For the use of the channel is a graphic master one of

This document is translated from: How to Close Channels in Golang elegantly.A few days ago, I wrote an article explaining the use of channel in Golang. In Reddit and HN, that article received a lot of approval, but I also received the following criticism about the Go Channel design and specification: There is no simple and common way to check if the
the DMA efficiency. The DMA controller needs to do a lot of work for each data transmission. Increasing the data transmission unit means a decrease in the number of transfers. In addition, the DMA mode steals the entire cycle, and the CPU processing efficiency is reduced. To minimize the duration, we must try to improve the performance of the DMA controller, which can reduce the CPU output efficiency.

Recently, I have found an interesting phenomenon in various major markets. All the users who come to the Computer City to crash, whether beginners, game players or masters, chose intel p4c series processor (supporting hyper-threading) and the i865 chipset (supporting dual-channel memory technology) motherboard, it seems that the selection of P4 with hyper-Threading Technology and supporting dual-channel chi

of textures used in a channel exceeds the maximum number of hardware support, Ogre automatically divides it into multiple channels at run time (only when no fragment shader is used). Each channel has some top-level properties such as ambient light. Refer to 3.1.2 PassEach channel can contain 0 to more texture units, reference 3.1.3TextureUnit. Defines the textur
Dudu Voice based on the Internet real-time communication and team voice combined, is a high quality standard, the top server to ensure a stable voice communication, text communication, group communication, the lowest resources to achieve the most extreme user experience, to adapt to gamers, entertainment, life-long free instant messaging voice software. Suitable for instant chat, Game Voice, multiplayer K song, group function, etc.

Channels can be compared to RJ45 network cables, a total of 11 available channels. Considering that there are overlapping regions between the adjacent two wireless APs, in order to ensure that the signal channel used in this part of the region can not be covered by each other, the wireless AP with the specific signal covering each other must use different channels, otherwise it is easy to cause the signal of each wireless AP to interfere with each oth
Before learning the Photoshop channel mixer, we must understand the composition of the color and the principle of the channel.
In the color system, "red + green = yellow", "red + blue = Pinkco" "Blue + green = Cyan". In the display is in RGB mode, RGB three values are 255 display as white, RGB three values are 0 display black. Any image in the channel inside is
Green Blue has always been the main direction of Japanese style color, fresh and beautiful, quiet and elegant, but also popular style. We usually use Photoshop "optional color" and "level" and other tools to modulate the Japanese blues, you can get very good visual effects, but we can also through other ways to achieve a better and more broad goals, the so-called road to Rome. Here to introduce "channel mixer", intuitive understanding of "
the message. Instead, message delivery in the Actor model is asynchronous, that is, the sending and receiving of messages does not have to be done at the same time, and the sender can send the message before the receiver is ready to receive the message. These two schemes can be thought of as being dual to each other. In some sense, the intersection-based system can simulate the asynchronous message system by constructing a buffered communication method. The asynchronous system can synchronize t

Just to do video tutorials, for a long time did not write graphics and text tutorials, today we discuss the split channel and then merge the method to color.
With the tutorials, we're not just going to learn how to do this, it's more important to understand why we do this, and then we'll have a clear idea of how to do it again when we encounter similar problems.
What this tutorial can learn:

The channel is a core type in go, and you can think of it as a conduit through which the core unit can send or receive data for communication (communication).
Its operator is the arrow

Just like the map and slice data types, the channel must first be created and reused:
