Examples of exception detection methods and ideas based on Big Data Analysis 1 OverviewWith the deepening of information technology in human society, the data produced by information systems is also growing exponentially. In-depth analysis of such data can produce a lot of valuable information. Because of the large amount of data and the diversity of data attributes, classic statistical analysis methods cannot be applied. Therefore, Big Data Analysis

Examples show how hackers Execute SQL injection attacks"SQL injection" is an attack method that uses unfiltered/unaudited user input ("cache overflow" is different from this method ), this means that the application should not run the SQL code. If the application creates SQL strings with no precaution and runs them, unexpected results may occur.We have recorded the twists and turns that have taken place after many wrong turns, and a more experienced p

WPF 3D knowledge points and examples, wpf3d knowledge pointsIntroduction The reason is that a triangle is used to describe the most subtle ry of a plane. The rendering engine can calculate its color based on the material of each triangle and the lighting angle in the scene. In fact, it is three points to determine a plane. The calculation on a plane is the simplest, with the least factors taken into consideration. If three vertices in a 3D space a

it is suitable. After Gs is located in Vs, the following describes how to interact between the two shader. If we use GS, we must also use. GS uses vs to calculate the written uniform, including gl_position, gl_normal, and gl_frontcolor. We need to know That vs cannot modify the built-in uniform value, such as gl_vertex, but can write uniform such as gl_position at will.
