Once a friend asked me how to quickly online to a large table to add a field or modify the length of a field, the MySQL version is 5.6, so prepare a test environment to prepare a 100 million records of the table, and then to the actual test in which way faster, first to start preparing 100 million records of the table.I have hundreds of millions of records on the line of the table, but a lot of online friends are not, then I practice here a way to achieve their own construction of 100 million da

My colleague raised a question: How can I obtain the current file name in the JavaScript file dynamically inserted in the browser? Background My colleague raised a question: How can I obtain the current file name in the JavaScript file dynamically inserted in the browser? In addition to a file name output by the server, the following three methods should be obtained in the script. Solution The general solution can only be used for page static scripts label introduction or single dynamic loadin

Work encountered in the picture to Gray degree group needs, after research and the guidance of the great God, finally get the following two methods, can realize the bitmap to Gray degree groupThe simple bitmap to Gray degree group is: to get each pixel in the bitmap, and then based on the pixel points to get the RGB value, and finally the RGB value, according to Gray-scale algorithm to get gray value can be/* such as a picture of a 480*800, eventually

the following.So, for example, array[0]=100, we knew to draw a bar at x=0, a height of 100 units long, array[1]=50, and then in X=1 draw a column with a height of 50 unit length, and from this analogy, if you use a for loop to iterate through the array to draw it all out, is what you see.SamplingBut we're not going to have that effect, we just have to take a sample of all the data, such as setting a step 100, a progress pump, to draw some bars in the entire spectrum.Or first of all, according t

on internal elements. The perspective attribute defines the depth of the Z axis plane and the relative size of the elements above and below the plane. In general, the smaller the perspective value, the larger the object, the closer it is to you. The larger the perspective value, the smaller the object, and the farther away it is from you.

and the comments are very clear. After compilation, you can create the first HGE program. How is it? It's easy! Code: write: # Include "HGE. H" // contains the HGE header fileHGE * HGE = 0; // create a pointer to the HGE class.Bool renderfunc () // draws a function. After the program starts, HGE will continuously call it.{Return false; // if the program is normal, false is always returned. If true is returned, it will be executed from system_start.}Bool framefunc () // logic f

format. In this way, two-way real-time transmission of display content and status data is realized using the mobile communication network. Considering the simplicity, this paper uses a 32x64 dot matrix LED unit board to display 16x16 Dot Matrix Chinese characters as an example to describe the system principle. For larger LED screens, you only need to cascade multiple similar led unit boards through the "16 pin 08 interface.2 hardware implementation2.1 hardware interface circuit of TC35I module

Author: Song Baohua Source: Skynet 1. Basic Concepts First, we will explain the concept of Bitmap and palette with common statements. We know that all colors in nature can be composed of red, green, and blue (R, G, B. It can be divided into 0 ~ There are 255 levels, and different combinations of red, green, and blue are 256x256x256, so they can represent about 16 million colors. For human eyes, this is already "true color. For each vertex (r,gand bits), the extended file name in the computer is
