If you're like me, you bought your RPi to "control things" using the I/O pins on the RPi. Using Python and the RPi GPIO library, you can do just that. Python should already be installed on your RPi, and it takes just a minute to install the GPIO library:

Open the terminal on your RPi. Double-click the icon on the desktop named LXTerminal

Type the following command to download the GPIO library as a tarball:
wget http://raspberry-gpio-python.googlecode.com/files/RPi.GPIO-0.4.1a.tar.gz

Unzip the tarball:
tar zxvf RPi.GPIO-0.4.1a.tar.gz

import RPi.GPIO as GPIO ## Import GPIO Library
GPIO.setmode(GPIO.BOARD) ## Use BOARD pin numbering
GPIO.setup(7, GPIO.OUT) ## Setup GPIO pin 7 to OUT
GPIO.output(7, True) ## Turn on GPIO pin 7

Redirect All Requests To Index.php Using .htaccess

In one of my pet projects, I redirect all requests to index.php, which then decides what to do with it:

Simple Example

This snippet in your .htaccess will ensure that all requests for files and folders that does not exists will be redirected to index.php:

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-d

do
  echo $output
  usep=$(echo $output | awk '{ print $1}' | cut -d'%' -f1  )
  partition=$(echo $output | awk '{ print $2 }' )
  if [ $usep -ge 90 ]; then
    echo "Running out of space \"$partition ($usep%)\" on $(hostname) as on $(date)" |
     mail -s "Alert: Almost out of disk space $usep%" you@somewhere.com
