OverviewIn distributed systems, there are scenarios that require the use of a globally unique ID, which can be used to prevent ID collisions using a 36-bit UUID, but the UUID has some drawbacks, first he is relatively long, and the UUID is generally unordered.There are times when we want to use a simple ID and want the ID to be generated in an orderly fashion.The snowflake of Twitter solved this demand, and initially Twitter migrated the storage syste

Same Snowflake time limit: +Ms | Memory Limit:65535KB Difficulty:4 Descriptive narrative You may have heard and snowflakes are alike. Your task is to write a program to determine whether the is really true. Your program would read information about a collection of the snowflakes, and search for a pair, the May is identical. Each snowflake have six arms. For each

Twitter's engineer Snowflake also proposed a method of generating a unique sequence in a distributed system;The UUID in Java is also a desirable method, and his disadvantage is that the serial number is too long.The most primitive form of the snowflake algorithm is written in the Scala language https://github.com/twitter/snowflake/releases/tag/

Ctional light per pixel)In this section, we will change the previous shader code to the direction light calculated by pixel. We need to split jobs by two shader to determine which operations need to be performed by pixel.First, let's look at the information received by each vertex:• Normal• Semi-Vector• Light Source DirectionWe need to transform the normal to the viewpoint space and then normalize it. We al

Resolution, pixel, and PPI, resolution, pixel PPI Screen SizeIt refers to the length of the diagonal line of the screen, generally in inches, 1 inch (inch) = 2.54 cm (cm ). In the traditional sense, the photo size is also the concept. Therefore, screens of the same size (diagonal) may have different aspect ratio.Pixel: This is an abstract concept in a bitmap (such as a digital image). It refers to the compu

The Part is in some form similar to the whole, called fractal, and the Koch curve is a geometric curve shaped like a snowflake, so it is called a snowflake curve, which is one of the fractal curves, which is described as follows Let's start with an example: we can see that a small cluster of broccoli is a branch of the whole flower clusters, and they have a similar shape at different scales. In other wo
