Run your .net applications on Linux !

Let us suppose that you are one of the greatest .net developers across and you want to use the Linux as the operating system then what will you do ? Will you admit that Windows is better than Linux..! I will say no, dont cry for space ! You just have to use MONO and you will save the world  

Mono is an open source project (sponsored by Novell) that allows you to run .Net applications on Linux (as well as Unix, Mac OS X, Solaris and even Windows). To obtain it, go to the Mono download page and find the version you need for your distro’s. Once you’ve installed Mono, get one of your .Net programmers to create and compile a simple Microsoft Visual Studio C#.net console application. Just something easy, such as: 

using System;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World");
        }
    }
}

Run Multiple Virtual Desktops on your computer

Running Multiple Virtual desktops on your computer is easy with Desktops. This little program is from technet.microsoft.com by Windows Sysinternals. Since it is from Microsoft you do not have to worry about viruses or something like that. Using desktops lets you easily switch to a different desktop in just a matter of seconds. So, with desktops you can check your email listen to songs or something like that and on the other desktop you can browse the web or just chat with friends. You get 4 virtual desktops with this application and it just weighs about 115 kb.

Alter the colour of your Ubuntu

Ext4 File System

Ext4 file system (4th extended file system) is the next generation file systems, retaining backward compatibility with the previous file system, ext3. Ext4 was released as a functionally complete and stable filesystem in Linux kernel 2.6.28. Ubuntu 9.04 was released with support for the ext4 file system.

One of the most evident advantages of ext4 for end users is the drastic reduction in time taken to do an fseek operation of your hard drives. The other advantages of ext4 file system over ext3 are – it provides better performance and greater reliability. Also it increases the maximum file system size to a whooping 1 exabyte. Compared to this, ext3 supports a maximum of only 16 TB of file system size.

Bottom line : A drive with ext4 file system cannot be mounted within older Linux distributions as they don’t have support for ext4.
