One way to fast update all records in a MongoDB collection is to send an update with multi flag true. Example:

db.my_collection.update({},{ $set: { "Price" : 100 } }, false, true );

I use below script to show current module, controller, action name in Zend view.

$request = Zend_Controller_Front::getInstance()->getRequest();
echo 'Module: '.$request->getModuleName().' ';
echo 'Controller: '.$request->getControllerName().' ';
echo 'Action: '.$request->getActionName().' ';

To show which processes are listening to which ports on a Linux machine you can use:

netstat -atp | grep -i "listen"

On Mac OS X you can use:

lsof -i | grep -i "listen" 

If you have attached an external mouse to your laptop, you may not need touchpad which may be accidentally touch. I’ve made a short script to disable and enable the touchpad.
1: Disabling the TouchPad

#!/bin/sh
dev=`xinput --list | grep PS/2 | grep Generic | cut -f2-2 | cut -c 4-10`
export DISPLAY=:0
xinput set-int-prop $dev "Device Enabled" 8 0
echo "Device id=$dev has been disabled"

2: Enabling the TouchPad

#!/bin/sh
dev=`xinput --list | grep PS/2 | grep Generic | cut -f2-2 | cut -c 4-10`
export DISPLAY=:0
xinput set-int-prop $dev "Device Enabled" 8 1
echo "Device id=$dev has been enabled"
