Just Spring

Good book to kickstart Spring Framework

By Aneesh Joy from Cochin, India on 9/26/2011

 

4out of 5

Pros: Easy to understand, Well-written, Concise

Best Uses: Intermediate, Novice, Student

Describe Yourself: Developer

This is a good buy if you know core Java and want to jump in to Spring Framework. This is a small book and you can get the fundamentals right within no time.

It is very true that project deadlines don't allow developers to read fat books cover to cover. This one will definitely get you started and you will get the confidence to sail through a significantly huge spring framework.

Although the book gives a simple introduction, author also tried to provide common use cases like using Java collections, JMS, and JDBC with Spring.

Mobile Credit Card Transation using OTP

Today I made my first Mobile transaction using OTP. OTP stands for One Time Password.

From 2011 Feb onwards I was  not able to do Credit card transations using mobile due to a new rule from Reserve Bank of India. The rule says you can not do online credit card transactions without 3D secure passwords.

Its a good move from RBI. Even if you loose your Credit Card, nobody use it for online transactions without your secret password.

That's about online web transactions..what about mobile transactions...?? Mobile world  does not yet support alpha numeric 3D Secure password.. only numeric passwords....

For mobile world the corresponding technology is OTP. To do any CC transaction from mobile your need to first generate a One Time Password ( OTP ). Its numeric..can be used only once...even if the transaction is failed.

To generate OTP you need to send an SMS to a designated number. Number and message format varies from bank to bank.

You will get a message with your OTP. OTP should be used with in 2 hours after generating it. After 2 hours its invalid.

Ok. Good... If your Credit Card is stolen nobody can misuse it for doing mobile transactions.Great!!

Question to RBI: What  if Credit Card and Mobile is stolen...??? Isn't that possible ???

SUPER MOON witnessed from my terrace

Yes. I have witnessed Super Moon from my terrace.

What is QR Code?

I was just wondering what are these images... I knew for sure that these were targeted for mobile phones. But noting more than that. What are they used for? How are they used?...

Most of you at some point of time definitely must have come across these boxes with black and white patterns. You generally find it in newspaper advertisements...Flex boards placed on highways....

Yesterday I figured out that these are bar codes designed for mobile phones. The bar code reader is your camera mobile phone.

I tried it..its really interesting.. you can read these QR barcodes with your mobile phone....just that you need to install a bar code reader software. Which can be freely downloaded from internet.


The interesting part is that you can create these codes you own..there are many web sites which offer this service.

Now, coming to the code..what data can be encoded.. Text, SMS, Phone Number, Address, URL.

Use Case1: Point your camera to a QR code placed in a flex board adv. go to the web site in one click.
Use Case2: Point your camera to a QR code in a news paper adv. call the guy in one click.
Use Case3: Point your camera to a QR code in a news paper adv. send an SMS

In fact, use of this code is limited to your imagination.

So, here's your home work.. scan the QR code I have given above with your mobile and see my secret message to you....enjoy!!

For more details google "qr code"

Happy New Year 2011!!

Interesting to know that I am in a new year. But as usual I don't see anything different. Just another day.
Last year also lots of things happened in my life..eventful year it was....

It was last year that I got married to my lovely wife....I came back to native town...settled at my home with family .. this was totally unexpected.

Last year I started using facebook. Played FarmVille ..with family.

I did not blog for almost 6 months last year......I am no longer online in gtalk 24X7 as I don't have gtalk access in office.

First time I visited Munnar in my life time..and thus high range areas in Kerala.

Five of my close friends got married last year.

And the final surprise last year was that I got a mystery gift in December!!
