There are so many reasons why having a Linux distribution on a USB drive can come in handy. From having a “rescue” OS on your keyring to being able to install a new distribution on your EeePC, a “thumb drive” Linux has many uses. But getting Linux onto a USB drive can’t be simple. Right? Wrong. There is a tool, UNetbootin, that makes installing Linux on a USB drive simple.

Sometimes after a partial upgrade of Ubuntu you suddenly find that it has broken down the System Dependency Tree and now you are unable to revert back the changes.

In such cases there is a very simple command that reinstalls all the distribution packages and reconfigures them automatically.

One thing any hacker should know is how to hack into login account of any operating system. Major Operating Systems that are used these days are Windows, Linux and Mac. So today I will show you how to hack into these Operating Systems. Are you curious how easy it is for someone to gain access to your computer? If so, read on to see the technique one might use to figure out your computer password.

If you run a dual-boot system with Linux and Windows, this has happened to you. You had to do your monthly reinstall of Windows, and now you don’t see the linux bootloader anymore, so you can’t boot into Ubuntu or whatever flavor of linux you prefer.ubuntuIf you run a dual-boot system with Linux and Windows, this has happened to you.

Over the years that I have used Ubuntu, other than the usual Ctrl + C (copy) and Ctrl + V (paste) shortcuts, I have discovered quite a number of keyboard shortcuts that are very useful, but seldom used by many. If you are looking for more keyboard shortcuts to add to your collection, I am sure you will be able to find some new tricks here.

When asked to most of the users “How will you uninstall Linux when it is Dual Boot installed with Windows XP?” The common answers we got was “Start windows XP and format Linux Partition”. Well they were half correct, you do have to format the linux partition but what about the grub loader? The grub loader will still be showing you the option to boot Linux during the start up and by mistake if anybody goes for booting linux, the system will not find any linux on your machine and it will restart. so what can you do in this situation?

We all know that the simplest function in Linux is fork(). The fork is used create a child process which is an exact copy of the calling process (parent process). You might be thinking how can such a simple function reboot a linux machine. Well I must tell you that the program I am going to discuss today uses only this fork function and can force a Linux Server which can serve as many as 100 computers to get rebooted. I have tried this on my College’s Linux Server which Serves more than 200 computers at a time and I was lucky to get out of this situation.

Linux rarely needs to be rebooted. But when it does, it’s often slow to boot. Fortunately, there are ways to speed things up. Some of these methods are not terribly difficult. (although some, unfortunately, are). Let’s take a look.
