Netbeans is a great IDE and with every version lots more features are introduced that make it even better. One thing that I like to use is the code templates, which have been available from version 6.5. Code templates allows you to type a simple command and get a section of code.

There is one thing that should be followed no matter what sort of form you create and this is the rule of Simple Input Detailed Output, or SIDO for short.
Last month I started writing functions in a particular way, which has made my life as a programmer much easier on more than one occasion. No matter how many comments or verbose parameter names you put in you can end up writing code that you will get lost in. The reason is simple. Lets say you had a function that took in a couple of parameters.
As the new Google web browser was released last night (I'm writing this post using the new browser) I thought it would be good to update our readers on the user agent string that this web browser has.
