While many PC users stick with the operating system that comes with their PC, others enjoy dabbling in other operating systems. If you want to use two operating systems on the same computer, you have a couple of options. The first is to simply create another partition on the hard drive, while the other is to use an external hard drive. The latter is the easier option and requires only that you change the correct settings to install the second operating system on your external hard drive.  Things you will need Blank CD-R or DVD-R Program to burn the .iso file Instructions 1. Check to make sure that your particular operating system can be run on an external hard drive and supports dual-booting so you can safely run two operating systems on your computer.

The first byte asks, “Are you ill?” The second byte replies, “No, just feeling a bit off.” * * *  Software is like sex: It’s better when it’s free. * * *  Q: how many programmers does it take to change a light bulb? A: none, that’s a hardware problem * * *  “Knock, knock.” “Who’s there?” very long pause…. “Java.” * * *  A physicist, an engineer and a programmer were in a car driving over a steep alpine pass when the brakes failed. The car was getting faster and faster, they were struggling to get round the corners and once or twice only the feeble crash barrier saved them from crashing down the side of the mountain. They were sure they were all going to die, when suddenly they spotted an escape lane. They pulled into the escape lane, and came safely to a halt. The physicist said “We need to mode...

Following are few very useful Java code snippets for Java developers. Few of them are written by me and few are taken from other code reference. Feel free to comment about the code and also add your code snippet.     1. Converting Strings to int and int to String String a = String.valueOf( 2 );   //integer to numeric string int i = Integer.parseInt(a); //numeric string to an int 2. Append text to file in Java Updated: Thanks Simone for pointing to exception. I have changed the code. BufferedWriter out = null ; try {      out = new BufferedWriter( new FileWriter(”filename”, true ));      out.write(”aString”); } catch (IOException e) {      // error processing code } finally {      if (out != null ) {          out.close();      } } 3. Get name of current method i...
