To give you Photoshop software users to share the details of the fashion of the snowflake effect of the production of a tutorial. Tutorial Sharing: Original: 1. First we get the original image into the camera Raw, first we see the data straight square, the upper right corner, there is a white triangle description of the picture, but is white to show the color of the explosion, If it is the other color descr

It's snowing. This article mainly introduces how javascript can fly snow. It has some reference value. Interested friends can refer to the examples in this article to share with you the javascript Implementation of snowflake fly effect, for your reference, the specific content is as follows: Principle: 1. js dynamically creates a DIV and specifies the CLASS to set different background image styles to display different

, NHibernate provides the comb algorithm (combined Guid/timestamp) in its primary key generation mode. The 10 bytes of the GUID are reserved, and the time (DateTime) in which the GUID is generated is represented by a different 6 bytes.Test with the above algorithm, get the following results: As a comparison, the previous 3 is the result of using the comb algorithm, the last 12 strings are the time sequence (unified millisecond generated 3 uuid), over time if generated again, 12 strings will be l

Snowflake algorithm Snowflake is the open-source distributed ID generation algorithm for Twitter, and the result is a long ID. The core idea is: use 41bit as the number of milliseconds, 10bit as the machine ID (5 bit is the data center, 5 bit Machine ID), 12bit as the number of milliseconds (meaning that each node can produce 4,096 IDs per millisecond), and finally a sign bit, is always 0.

Koch curve is a geometric curve shaped like a snowflake, so it's called a snowflake curve, which is one of the fractal curves, as follows:1, arbitrarily draw a positive triangle, and put each side three equal;2, take three equal part of the middle section of the side to make a positive triangle, and the "middle section" wiped off;3, repeat the above two steps, draw a smaller triangle.4, repeating until inf
