CSS snowflake animation
design sketch: Project address:https://codepen.io/jianxiujiu… The structure of HTML is as follows. Create 10 snowflake elements. In fact, three or four elements are OK. The more elements there are, the more snowflakes there are, and the speed of snowflakes is different, which will appear more layered. <body> <div class=”snow”></div> <div class=”snow”></div> <div class=”snow”></div> <div class=”snow”></div> <div […]

First, they are relatively long. In addition, UUIDs are generally out of order Sometimes we want to use a simpler ID, and we […]

Discussion on distributed unique ID generation scheme from mongoid generation
background Mongodb must have been used by everyone. After the data is loaded into the disk, when you query the data, you will find that it will automatically generate a_ “Id”, such as: db.test.insert({“name”:”tom”}) Query results: { “_id” : ObjectId(“5fd049327fbb28868f4660a5”), “name” : “tom” } Mongoid is used as the primary key index. Even in the […]
