We have long lacked a way to judge whether a user is browsing a specified tab. Does the user go to another website? Did they switch back?Now, the HTML5 page visibility interface gives programmers a way to use Visibilitychange page events to determine the state of the current page visibility and to perform certain tasks in a targeted manner. There are also new Document.hidden properties that can be used.Document.hiddenThis new Document.hidden property, which shows whether the page is the page tha

The example in this article describes how Android gets to listen for SD card status. Share to everyone for your reference. The specific analysis is as follows: 1. Register Storageeventlistener to monitor the SD card state that is the onstoragestatechanged () method, when the SD card state changes, call this method. Copy Code code as follows: public void onstoragestatechanged (String path,st

Because the script written above is not very useful, each time you add a firewall rule, you need to manually delete the MD5 file. So we re-wrote a shell to determine if iptables was modified by calculating his rule number.#!/bin/bashiptable_num=$ (sudo/sbin/iptables-l-n|wc-l) if [${iptable_num} = 8];then echo iptables is stoped exit 1else Echo Iptables is started $iptable _num exit 0fiIf the great God has any good way to welcome the recommendation. Thank you!This article from "Do not abandon!" D

Mysql itself is not powerful in performance monitoring, which makes many MySQL DBAs sleep at night,Fortunately, the MySQL database status is monitored through cacti (note that monitoring is not monitoring ).With the powerful drawing function of cacti + rrdtool and dedicated MySQL templates, You can flexibly and quickly create and monitor multiple MySQL instances. (I) For RPM installation, the following RPM
