Five quick detox tips foe Linux

Five quick detox tips

  1. Customise your distro Revisor, bundled with the latest Fedora release, is perfect for creating your own customised distribution and putting it on to a USB stick. A customised distribution will enable you to fine tune your own requirements as well as helping to keep your data to a minimum.
  2. Rescue is at hand If you run into problems restoring from a backup or reinstalling the operating system, have something such as SystemRescueCd close to hand for troubleshooting. This can help with LVM and booting as well as getting at your backup archives and even old data.
  3. Ghost a working install Use Partimage to make a ghost copy of a freshly installed and configured Linux installation. This can save you a great deal of time if you just need to quickly reinstall your system and it's perfect as a backup medium too.
  4. Remote storage Store your transferable data on an alternate drive. You can then wipe your Linux installation knowing that your important data is still safe. If it's network-attached storage, there's the added advantage of universal access.
  5. Use symlinks Symbolically link directories you know you want to keep using ln -s source destination. If the destination is on a remote drive, you only need to restore the symbolic links on a fresh installation to get access to your old data. Links will be saved as part of a backup, which is handy.

Creating Seamless Virtual Machine with Virtualbox 1.6

Creating Seamless Virtual Machine with Virtualbox 1.6


Virtualbox 1.6, which was released in May 2, was the first major release since Sun took over virtualbox. All I can say is Wow!! This is perhaps the single biggest, most important open source release which will change the face of how computers are used for years to come. Hell this is even bigger than the release of hardy heron (IMO), and Ubuntu 8.04 LTS was a very important release.

One single feature of virtualbox, seamless, will make some major software completely redundant in coming years. Don’t get me wrong, seamless was possible with virtualbox since the last release before 1.6; but it was buggy, not a part of the features and needed a decent amount of hack and workaround to even get it to work. So seamless was possible, but never like this. With virtualbox 1.6 seamless is truly effortless, and well integrated, and super fast.

I think because of seamless virtual machine, the use of software like wine (compatibility layer for running Windows programs on linux environment), Cygwin (Linux-like environment for Windows), or a commercial product for a virtual machine like vmware, will be redundant. For developer like me, who constantly have to switch back and forth between linux and windows environment, this is god-send.

For a list of new features, bug fixes, check out the official changelog: http://www.virtualbox.org/wiki/Changelog

So lets get going and see how to install and setup seamless virtual machine.

Installing Linux guest in Windows host and configuring seamless mode

Step 1: Setting up Virtual Machine

Download and install virtual box for windows over here.

Create a new virtual machine but clicking “New”:

Choose a name for the virtual machine, choose the distro you would like to install. For this example, I chose Ubuntu.

Next we have to select the base memory. Here I would like to say a few words. Virtual machine are not for all systems, with the decreasing price of ever so powerful dual and quad-core systems, it would be a good investment for you to truly experience the integration of seamless virtual machine. Memory is also very important, I am showing this example on a quad-core with 3Gb of memory.

I am using 1GB for my virtual machine.

Next we will create a virtual dynamic disk for the virtual machine:

The rest of the selection process is pretty straight forward:

I choose 2GB because that all I need for this example, you can choose whatever amount you like.

After creating virtual disk, it should give you summary and that should end the wizard. Before you go on and start the virtual machine you have to assign the Ubuntu image file you should have downloaded by now before instalation. Just mount your ISO image file to the virtual machine cd drive:

Go ahead start the virtual machine by clicking start on top of the menu. Now the OS installation (Ubuntu here) should start. After you are done with installing the OS, go to the next section to configure seamless feature.

Step 2: Setting up Seamless

Before you restart after installation, make sure you unmount the OS image file, the same way you mounted it.

Now we will install “Guest additions” (Device –> Install Guest additions), which will add many of the features needed to enable seamless and other features of the guest OS.

Double-click or run the file VboxLinuxAdditions.run as root, which will install guest additions.

Restart guest ubuntu OS, go to Machine –> Seamless mode. Now you should have two OS running side by side, with the ability to copy&paste any information, without having to press “host” key to switch back and front from guest OS.

This is how my Desktop looks like now, very cool stuff. :)

5 Free Apps to Clone Your Hard Drive

5 Free Apps to Clone Your Hard Drive

Hard drive prices are so low now that it really makes sense to use an imaging program. That way you've got a perfectly cloned backup of your system exactly the way you have it configured in case of a crash, which is much more convenient than reinstalling Windows, activating, and loading all your applications all over again.

Here are four great apps to get the job done - without spending a dime!

DriveImage XML. Runtime Software has never placed too much importance on looks, and it's for a very good reason. Their software works really, really well. DriveImage was the first software I used to create images within Windows. Scheduled backups can be created with the Windows Task Scheduler and command line switches. DriveImage is free for private, home use only. Yes, Macrium Reflect does the same thing and looks nicer, but it's $39.99.

For a straight-up, drive-to-drive clone, you can use Runtime's Shadow Copy. Shadow copy is free for everyone, not just home users.

Like DriveImage, XXClone runs in Windows. It has an extremely simple interface, and gives you the option to copy volume ID to your destination and make it bootable. The interface also provides quick access to the Windows disk manager, in case you need to perform some quick drive tasks prior to cloning. XXClone is free for personal, private use.


Those who, like me, prefer imaging from the command prompt should try EaseUs Disk Copy. It's interface looks a bit like a Ghost/Partition Magic mashup. It's very easy to use, handles all types of internal and external drives, and will even work with dynamic disks. DiskCopy is free for everyone.

Linux buffs will urge you to try PING, which I mention in 5 Apps for a Painless Reformat. Ping can clone drives, create bootable recovery media, back up BIOS data, reset passwords, and clean your cat's litter box. Ok, not really, but it's got more tricks up its sleeve than any other free cloning solution.

Did I miss your imaging app of choice? Comment it!
