NetBeans Tech-Talk / Demo at NIT Durgapur

Finally I had my first talk at NITDgp !!!
Response was awesum!! More than 60 (to be precise 67) people turned up so LG-C3 being the biggest classroom at the Computer Science Dept was almost full.Inspite of two other events going on paralelly in the college the turnout was highly unexpected.The reason of the huge turnout was I feel the very Sun Brand !


In the first part of my Demo I covered many topics related to Netbeans Intelligent Text Editor and showed them techniques like Code-Insertion , Code-Refactoring ,Using Javadoc , Live Code Parser and error checker ,
Local History , Code completion , Instant renaming , Compile on Save,and lots of other cool stuffs.
I explained them how to use the Profiler and the Debugger.
I explained them the use of Version Control and automated testing (Unit Testing) .


This was followed by a basic demonstration on the Swing Gui Builder and with functionalities like Automatic feedback , Quick Component Insertion , Anchoring , Alignment .


After this I expained the basic features of event handling and demonstrated it with a small application built using the Swing Builder .


As people asked for more meat so I continued out of my plan to demonstrate them easy Data Binding using MySQL database , JTable and Java Persistence API showing them how to createa CRUD application in 5 mins!


On public demand I also showed them how to import an existing PHP-MySQL project in Netbeans and showed them advantage of using WEB 2.0 frameworks like JMaki and Dojo directly into the existing PHP project.


I gave them an introduction to Visual Web Java Server Faces by demonstrating them how to populated a Woodstock Table from a MYSQL database using simple drag-drop.

Many obvious questions like why Netbeans over Eclipse which I think I answered satisfactorily. Many people came to me afterwards asking more details about multibooting Solaris and more about Web 2.0 and AJAX.
I was on the top of the world when people actually clapped at the end of the talk.
All in all a nice experience. Waiting to have many more sessions like that!! .

My First Experience with Virtual Box

I had already been using opensolaris on my laptop within a dual boot system but sadly few days back my laptop got spoilt that too the system board . I got a laptop from my
sister's friend on a temporary basis . I was obviously not allowed to install a new OS on to it. It was when the idea came to my mind about installing opensolaris on VirtualBox . The reason why I chose virtualBox was because I had earlier used Vmware and my experience was not good at all.
As now I have successfully installed opensolaris on virtualBox and everything is working excellent I want to share my experience with you all .
Infact with VBox you won't find any difference between a metal installed opensolaris and virtually installed opensolaris .

INSTALLING VIRTUALBOX
You can get binaries for all platforms from the site below.The site also contains a user manual which is more than sufficient to get you through the initial installation procedure.

Starting the OpenSolaris virtual machine installed in VirtualBox











OpenSolaris desktop (1280 * 600 resolution)

(One of the main nuances I faced in installing Ubuntu as a guest in VirtuaBox is that I found it very difficult to configure the screen resolution. I spent so much time in something which should have been a easy task. I even wrote a blog entry about increasing the screen resolution in Ubuntu. But in OpenSolaris, I got the maximum resolution just by installing the guest additions.)



And access to the screen resolution setting cannot be this simpler. Just right click anywhere in your desktop and you are there.



And here is the actual screen resolution user interface


Some Applications pre-installed in OpenSolaris



Package Manager

(One good thing about OpenSolaris is that it comes preinstalled with most apps needed for a Java developer)
