The Linux kernel is the operating system kernel used by the Linux family of Unix-like operating systems. It is one of the most prominent examples of free and open source software. Ubuntu is a computer operating system based on the Linux distribution and distributed as free and open source software, using its own desktop environment.
There are several reasons to upgrade the kernel. One is to take advantage of a specific new feature or driver; another is to be protected against a security vulnerability, or just to maintain an up-to-date and healthy system. So, from time to time it may be wise to upgrade your Linux kernel. Even if you choose not to update to every new kernel revision, it is recommended that you at least upgrade from time to time. It is strongly recommended that you immediately upgrade to a new kernel if that new release solves a security problem.

Ubuntu team developed live file-system which can be booted on system without installing the operating system on hard disk (even with persistent storage which allow you to save changes on pen drive). Most of the Linux systems incorporated this technology in their distributions which allowed people to run Linux distros on CD/DVD or pen/flash drive prior installing it on their systems. By live-booting, you can check that your system is supported by the Linux distribution and take a test drive of the operating system. BUT, how you’re going to run your favorite Linux from pen drive? So, I’m going to tell you the procedure to Boot and Run Linux from pen drive using UNetbootin.

Linux Mint 12 KDE is very easy to use and glossy at graphics appeal. Windows users, moving to Linux will find to be pleasantly simple using Linux Mint KDE. This release is based on Kubuntu 11.10. Linux Mint is a developing Linux distribution and for past some releases, Linux Mint has taken KDE, LXDE, Xfce based versions of Linux Mint as official releases. Recently, I got opportunity to get my hands on its latest KDE edition (Linux Mint 12 KDE version). I was little bore of my Ubuntu 11.10 and wanted to try something new. I thought to give KDE a try, as I’ve not used KDE for last seven months. Some time before, Blue Systems sponsored Linux Mint to work in collaboration with Netrunner (a KDE based Linux distro) to develop KDE with innovation. I must say that they’re working really good, Linux Mint 12 KDE is awesome (with small exceptions).
