If you have your passwords set to expire automatically on your system for security reasons, there may be times when you want an account who’s password doesn’t expire (such as if you are using a cert or if you have a program or service connecting to a low access account).
You can set up just the one account not to expire by running the following command:
passwd -x -1 <user_name>
This is great to make sure that people are not signing in and leaving their connection open. Who knows who can come over and start using that already authenticated connection?

This is a great way to setup accounts so that you know that the password you provided will be sure to go.

One interesting problem I have encountered in Android development is that the when you rotate the device it restarts the activity from the start. This is very annoying espeical to the end user who can get the splash screen again or have to start to from the begining of the app.
With a few simple lines of code you will be able to prevent this screen rotation from taking place.
Step 1: Edit your android manifest.xml file to add in the following line to where the activity is displayed:
android:configChanges=”keyboardHidden|orientation”
Step 2: Add the following to your activity:
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
}
