Lab job: Use the same system call using the Library function API and the embed assembly code in C code20135313 Wu Ziyi. Beijing Institute of Electronic TechnologyThe first section uses the Library function API to obtain the user identification number. The library function is Getuid ()The code is as follows:After the compilation runs, the user ID number 1000 is printed and output on the screen.The second section uses assembly to trigger the system call

Lab mode quick to create beautiful brown lomo Non-mainstream pictures
The author has a very deep understanding of the Lomo style, so it is easy to color. No matter in any mode can quickly pull out good-looking effect. Lomo style pictures do not have a special definition, color matching when only the screen with a hazy gray tone, there are obvious dark angle and so on.

Final effect
1, open the photo, press ctrl+
This method can be easily optimized for color and lightness with fewer steps, and the original piece that is adapted for this method must meet the following three conditions:
1, there is no obvious color bias in the image. 2, the image does not have one or several colors saturated excessive. 3, the image has not used the USM sharpening filter.
Some people say that the RGB mode is faster, RGB is really faster, just in the RGB mode of any channel will change the image of the light and shade stru
The tutorial palette is unique. The author pays more attention to the color of the high light part of the picture, and increases the texture and the ruddy color of the skin, which is completed in the high light area. Especially in lab mode, the picture is sweeter with the high light selection palette.

Final effect
1, open the original image, copy a layer, execution: images--adjustment--shadow/highlight, parameters
This tutorial is mainly introduced under the lab channel, adjust the curve to choose different channels to change the color, but also use the channel of the selection to enhance the local color. The method is more novel and worth studying.

1. Open the original selection menu: Image > Mode > Lab colors, and then create a new adjustment layer selection

Lab brightness channel sharpening is one of the most commonly used sharpening methods for professional photographers. it can avoid the color halts and colors generated during sharpening and make the sharpening look more natural, it also makes it possible for us to sharpen an image multiple times. This sharpening technique comes from Scott Kelby's Photoshop CS3 digital photo professional processing techniques book
Lab 1 part 3:the kernelNow we will start to discuss the Jos kernel in detail. Just like boot loader, the kernel begins with some assembly statements that set things up to ensure that the C-language program executes correctly.Using virtual memoryWhen you run boot loader, the link address (virtual address) in boot loader is the same as the load address (physical address). But when the kernel program is entered, the two addresses are no longer the same.T
Lab Purpose
In the C language environment (Turbo C or Vc), write a simple application to manage student status.
Through this experiment, students can skillfully write basic applications in the C language environment.
Lab Significance
Through this experiment, students can further understand the use of structures and arrays in the C language and be familiar with basic input and output methods.
The effect of the tutorial is very personalized, the production of only need in lab mode to copy B channel to the Brightness channel, you can get preliminary results. Later adjust the color and the appropriate sharpening can get the effect we need.OriginalFinal effect
