Other databases define tables using columns or other parameters. This definition is sometimes very complex, especially when the database is large. The rrdtool database is mainly used for monitoring. Therefore, the structure is very simple. The parameters that need to be defined are the variables with values and the files of these val

Python multithreading is a bit of a chicken, the application of the scene is limited, multiple cores per unit of time can only run a single thread.There is a pool, four pumps, but only one person, one can only open the management of one of them, so four pumps are useless. However, if the pump's operating time and cooling recovery time is 1:3 (thanks to Inoahx, it has been changed), then the utilization of the configuration is as high as 100%.Run code directly single.py#!/usr/bin/python3#-*-codin

These numeric keywords are used to define a mapping relationship with the font's associated characteristics, that is, the weight of the font is divided

In jquery, I can directly use show () and hide () to display and hide elements. This is easier than the operations in js. At the same time, show () and hide () you can also set parameters so that our operation has a cache effect. I will introduce it to you later. Basic usage Show () methodThe hidden The Code is as follows: Copy code $ (". Btn2"). click (function (){$ ("P"). show ();}); Hide () hides visible The Code is as follows: Copy code
