Android: Keep the Screen On :: 2011/06/15 04:07
안드로이드 애플리케이션에서 스크린 슬립모드로 자동 전환되면서 화면이 꺼지는 것 방지하는 방법이다. 레이아웃 XML 이나 코드 상에서 설정할 수 있는데, 아래 세가지 어느 방법으로 해도 된다.
1. AndroidManifest.xml 에서가 아닌 layout 파일에서 다음처럼 속성값을 준다.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:keepScreenOn="true"
>
2. 코드에서는 Activity 생성 시 다음과 같은 코드를 추가한다.
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
3. 또는 View에서 아무곳에서나 다음 메소드를 호출하면 된다.
(내부적으로 WindownManager의 FLAG_KEEP_SCREEN_ON 플래그를 설정)
setKeepScreenOn(true);

How to remove MySQL completely Mac OS X :: 2011/04/17 13:46
The steps:
First you need to edit the file in: /etc/hostconfig and remove the line
Since this is a system file I advise you to open it with nano in terminal:
Open Terminal
sudo nano /etc/hostconfig
Enter your password if you’re not authed yet.
Delete the following line: “MYSQLCOM=-YES-”
CTRL+X (This is the command for closing NANO, Enter the “Y” key to save the file and exit nano).
Second step:
Make sure MySQL is not running.
Open Terminal and copy and paste and run the following commands:
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm /etc/my.cnf
MySQL is now removed from your MAC.
