Add Extra Swap Space To Your Linux Box with a USB drive [Linux Hacks]

You must have heard about a feature called “Readyboost” in Windows Vista and Windows 7, which lets you add a flash drive or USB thumb drive as an extra drive for disk cache. By using this feature system performance is significantly increased, as the newly added flash drive increases the virtual memory of your computer.

In a similar way, you can use a USB flash drive to add extra swap space to your Linux OS. Increasing the swap space means increasing the system performance. Christer Edwards has written a shell script, which allows you to add a USB drive as an extra swap space in Linux. You can download the shell script file from here :

The steps required to use the extra space on the USB drive as swap space are :

  1. Insert USB disk and allow KDE/Gnome to auto-mount the device.
  2. Open a Terminal and run ./ -n to create a new swap addition.
  3. After executing these steps the swap space would have been increased, by the amount of free space on the USB drive. You can check the available swap space for your Linux OS with swapon -s .

When you no longer want to use the USB drive as an extra swap space, you can do the following:

  1. In the Terminal, run ./ -d to delete added swap and safely unmount your USB disk.
  2. Your swap should now have been reduced by the amount of space previously added. swapon -s will now show only your default swap space.

Note: This script is still in alpha stage, so use it on your own risk.

Run Live Linux CD In Windows [How To]

The best feature of most of the Linux distributions is that, they let users to try the whole operating system and all applications without installing them locally on the computer. Linux distribution CDs that provide this feature are called Live CD.

To boot a Linux distribution from a Live CD, you have to insert it into the CD drive and reboot your machine.

But usually there is no possibility to save configuration data and files that you work with, when you boot from a Live CD.

For this reson, we will show you how you can run Live Linux CDs inside Windows. MobaLiveCD is a freeware application for Windows Operating systems, that emulates the Linux Live CD inside Windows using Qemu. It offers a quick way of testing a Live CD without having to boot the computer. It takes only two clicks to start a Live CD inside Windows with MobaLiveCD. This freeware requires a Live CD in ISO format on the computer. Here is a list of all Linux Live CD’s.

You can download MobaliveCD from here.

The disadvantage with this kind of emulation is that a Linux Live CD cannot be   used inside Windows to determine hardware compatibility. Also emulation of a Live CD inside Windows is slower than booting from a Live CD.
