Moon in the Water
Moon-in-the-water happens when the moon shines in the water.When there is no moon, there is no moon-in-the-water.When there is no water, there is no moon-in-the-water.

The Convergence
Analysis and Data are not two things, they are one thing. Big Data is about both together!
Not so long ago, we used to have programmers who programmed, and DBAs who managed the data. We forgot that both enterprises were about providing analysis to the users
BigData Solutions
Big Data Solutions include traditional (relational) databases. They also include the more recent open source NoSQL databases. They include the traditional programming methods, but they also include functional programming methods exemplified by Hadoop or Map/Reduce.
The focus is on getting analysis results quickly, and being able to do so even when the problem statement changes on a daily basis.
Traditional (pre-Google) programming fits the above definition. But we think it would be misleading to call it Big Data if all you are doing is traditional programming.

Hands on Hadoop with Amazon EC2
Posted by J Singh | Filed under Amazon AWS, Map Reduce, Hadoop
A few months ago, I gave a talk at the Chelmsford Technology Skill Share Group. It was focused on the whys and wherefores of NoSQL and Map/Reduce. If you are interested in a copy of the presentation, please contact me.
Next week (9/14/11, 4:00 pm, Chelmsford Public Library, McCarthy Meeting Room. Directions.), I'll be giving a hands-on introduction to running Hadoop on Amazon EC2.
It will be as hands-on as the previous talk was conceptual. For the actual material, we will use the excellent tutorial by Michael Noll. Michael first wrote it in 2007 and has kept it up to date. The tutorial helps you install map/reduce and use it for computing the count of every word in a large text. We will use Ulysses by James Joyce as our sample text. Can we do this in 90 minutes? Yes, we can. But the goal is to get the most out of the journey.
To get the most out of the talk, you should be prepared to sign up for an Amazon account. They require a credit card but the credit card won't actually get charged because our usage will be a few ...
