iJava

When Apple Computer decided to rehire Steve Job back. Nobody has imagined Steve will drop "Computer" from Apple. When industry was galloping with Microsoft Windows, Sun's new wonder internet programming langugae Java. Everybody placing them self in World wide Web, Internet compatibilty ..... Steve job started interdoucing some products with iX. After iPhone it is almost impossible to ignore of  "i".
Th most interesting part in India 70% people get their first digital exprenece through a mobile phone. It is very common to use mobile and still illitrate about computers. The penetration of "i" devices is much deeper than computers. So the $ can be generated form "i" applications or services are much higher than PC. As a java progreammer I am excited I just need 18kb to run my JVM. It is interesting to see which platform will rule in "i" devices.

Size does Matter

Every time a girl dump me. I always think "Pallab its all because of that extra 10 kilo". The center of the body is the center of attraction. Then I hit the trade mill and keep hitting the new girl . Any way when I look at the history of application development. We started with command interactive programs, then nice windows based GUI programs ( thanks to Windows who copied from Apple who stole from Xerox ....). And now a days super sexy web application. From command based program to GUI based programs was a huge difference in user experience. Well when the web application came there was a great difference in designing. My teacher taught me for web application the client should be thin,dumb which can only take input and render the output.
And the the server side programs are like god. For everything they are responsible, Whether mandatory field is missing or calculating age of the user when user has already entered the date of birth.Every time it need to request to server. To keep our server as God who can not fail we have to really spend lots of resource.
In last five years we had some fantastic note book in the market and they ship with some amazing browsers. Now we can not blame IE for every stupid script error. It means we can afford to be fat I mean we can migrate something from servers to the client. As our users are already spent good money to have those note book and browsers, lets use them. Allow the client to grow let it become fat .... you will see your application is how intelligent and how it can save money for you ...  So love fat ones because they are smart :)

New operator is like growing Population !!!

Long back before 3 idiot movie of course even before five point some one. We must have realized life in india is a race. For every stupid thing staring from local bus to admission in higher studies and getting a job is challenging here. Why we have such a situation. The answer is pretty simple we are more than 1000 million people country. And we have not sufficient resource to handle it. Definitely I don't want to advocate here some family planning program or how to stop population growth. All of us know the solution for it. Only we need to use our operators carefully !!!
In our computer world the resource is keep increasing. The computers are faster it has more memory. Still I face the respect full errors like java.lang.OutOfMemory error. I was thinking how can I stop population i mean object population so that they don't have to race for memory,cpu etc. They can have a healthy life cycle.... I checked my code I found 99.9 % time I use new operator to create object ( 1% is the interview tips, we can create object using reflection api and Class.for ...) .
If I can use some kind of protection on new operator things will work .....
Then like conservative use new operator when its really required. You have no other object available to do the job.  then only create the object otherwise reuse the existing one .
Avoid new in Loop.  Less object Light application... Happy Users...
