What are the benefits of using the. xcassets? Will @1x, @2x, and @3x be built into the installation package together? What is the difference between PDF and @1x, @2x, and @3x? If I

Label: MySQL replication Problem of the last one, on the two-way synchronous replication architecture design of some design points and constraints.Problems and constraintsThe two-master double-write and bidirectional synchronization scenarios of the database mainly consider data integrity, consistency and conflict avoidance. For the same library, the same table, the same record in the same field of the two changes, will cause data consistency judgment conflict, as far as possible through the bus

Simple use of Images. xcassets, and use of images. xcassets In summary, Images. xcassets is just a few words.(1) The following is a simple arrangement.Enter images. right-click xcassets ---> New Image Set or click images of XCode. there is a plus sign in the lower left corner of the xcassets interface. The New Image Set is added and a New Set name is changed. For example, user_icon is used to drag your Image to the corresponding 1X, 2X, in 3X, 1X is

dimension, which is a technical operation, but it's a good start-meaning your design matches the grid of iOS and OS X. Working in a 1x environment also has the advantage of not having to keep in mind that all elements have to be kept even (0, 2, 4, 6, 8, etc.), greatly reducing Photoshop memory usage and faster operation. Although I have a Retina MacBook Pro, it should not change the way it works in a short time. The benefits of this approach are too much, even if the

You can flip one, two, or three coins each time. (Mock Turtles Games)The initial number starts from 0.When N = 1, the coin is positive, and the first hand wins, so sg [0] = 1.When N = 2, the coin is: Anyway, the first hand must win, the first hand operation may be: reverse or positive, the number of solutions is 2, so sg [1] = 2.When N = 3, the coin is reversed. The first hand must win. The first hand may be reversed, reversed, corrected, and reversed. The number of coins is 4, so sg [2] = 4.Pos

In the file system, the object is stored as a binary file, its metadata is stored in the extended properties of the file system, and it is recommended to use the default support extended attribute hungry XFS file system.
