. The average duration of each interruption is about 5 minutes, about 4 hours in total. About 50% ~ 80% of the interruptions are meaningless or rarely valuable. 1 hour per day, 7 hours per week, 365 hours per year, one person can study like a full-time student, 3 ~ You can become an expert in five years. If a person's desk is messy, he spends an average of one and a half hours searching for things every day and seven and a half hours every week. People who are good at using time will not spend t

ArcGIS flex API provides several common geometric figures, such as points, lines, and surfaces. When more geometric figures are needed, you need to expand the geometry in ArcGIS flex API. The general idea is to expand the polygon and the polyline of the linear ry. Polygon consists of an array of rings, while polyline consists of a path. Both ring and path are essentially an array of mappoint. Take a star as

1. Basic ConceptsClass of figure: a set of figures with the same characteristics is called a class.A kind of figure has the same sign, and different kinds of objects have different spectral characteristics (the ability to reflect and emit electromagnetic energy)Classification: According to the intrinsic similarity of each kind of sample, the process of dividing the feature space into several sets is adopted by some judgment criterion.2. Basic ideasThe

rate. It is worth further study and there are ready-made libraries available, such as STL. Other technologies are available: DirectDraw (described later), direct3dm, and OpenGL ES. However, development is difficult. 9. How to Use GDI + (native/managed )? GDI + is the next version of GDI, which has been improved and is easier to use. One advantage of GDI is that you do not have to know any details about how data is rendered on the device. GDI + has better implemented this advantage. That is to s

[Nagging] This section describes simple physical collision detection (non-box2d physical collision): collision detection between Rectangles and circles. [Simple collision detection] In some games, collision detection often occurs, such as whether the angry birds collide with the stones after they fly out. Although there is a box2d physical collision engine, you still need to master the simple collision detection method here. (1) rectangle and rectangle (2) circle and circle (3) rectangle

progress of medical work requires a decrease in the number of inpatients, while hypoglycemia indicates that the complication of hypoglycemia has increased.Further considering the increase in morbidity and other factors, the number of patients is increasing, so in fact, high blood sugar and hypoglycemia from 1999-2010 in the hospitalization rate are reduced, each 55.2% and 9.5%. The two trends are the same for age, sex and race. However, compared with the 65~74岁, the rate of hospitalization for

the Ctriangle, Csquare, and Ccircle classes from the Cfigure class, representing triangles, squares, and circles, respectively.We are going to instantiate the types of these objects, so in these derived classes, the Figuretype method, the circumference method, and the area method are implemented. Although the method names in these 3 classes are the same, they are implemented differently, similar to overrides but with a different meaning.How to understand? In the main function of this example, a
