VirtualBox from Oracle is a great application to run other Operating Systems within the native OS.
We installed virtualbox-4.2_4.2.12-84980~Ubuntu~quantal_amd64.deb on a machine with Ubuntu Gnome 64bit. While it showed no error in installation, but when run, it started to display following error:

Kernel driver not installed (rc=-1908)
The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing
‘/etc/init.d/vboxdrv setup’
as root. If it is available in your distribution, you should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.

So first we installed DKMS by running a command from terminal “Sudo apt-get install dkms”. This installed DKMS. Now as suggested in above error message we tried running ‘sudo /etc/init.d/vboxdrv setup’ and we were provided with another error message: Continue reading

Linux v. Windows – practical reasons for beginners to choose Linux.

An overview comparison of windows and Linux:

Ubuntu Precise Pangolin with Cinnamon Desktop.Window is like firmware. Very little scope for customization. Even though it does not sell hardware, it is like buying a phone with camera and music player etc. but without scope of expansion. Actually window’s popularity is due to its Games. However Linux is like a smartphone that has a lot of options. Once we install Linux, it brings with it loads of free software created by volunteers who created it for themselves and distributed it over the net.
At one time it could be said that, the first time computer buyer or for beginner, Windows is the safer option but that is not true any more. It was true, back then because the non-availability of hardware drivers. Linux was not able to run on large number of computers or support other apparatus due to non-availability of drivers. Now major hardware producers are supporting the Linux Foundation which is responsible for its core or kernel and compatibility of all major products are built-in kernel itself.
Here are some of the practical and day-to-day reasons which keep me stuck with Linux. Nothing emotional about it.

Windows’ Price

It is expensive. Worst problem is that a new version is rolled out every three years and it will not work on old machine, so we have to go out and buy a new machine as well. The worst part is dishonesty. The Microsoft first rolls out an alfa product as free trial and then sells beta product as new system. It keeps fixing the bugs and then it releases the final product as new edition. Look at past track record. Window 95 was a beta and 98 got it right. Windows 2000 and Millennium Edition were beta and finally XP was rolled out. Again Vista was a Beta and the Windows 7 was the final. My guess is Windows 8 is another Beta for touch screen monitor machines. Final will be the next.
Now after the purchase of OS, software is to be purchased which is no less expensive. Of course a pirated version is around the corner but why use a pirated when there is a free alternative which is also better? Continue reading
