So you are energized about HPCC Systems and ready to take the leap and "Jump In!" There are three things you will need to do.

For those who don't know me, here is a brief intro in the context of this blog post.

Some people say I talk a lot!? Just so you know, I am not all talk. I explore, I hack and I get it done; more often than not, I am on my own end to end on the getting it done side of things.

As the end of the 2012 calendar year approaches, at least for a good chunk of the world (and may come to an end on 12/21 for a crazy bunch), some people start celebrating holidays in different cultures and countries. I consider this season a good time to go over things to come in the HPCC Systems platform arena.

I often get asked about comparing the HPCC Systems platform and Hadoop. As many of you probably know already, there are a number of substantial differences between them, and several of these differences are described here.

This tutorial will walk you though adding a new feature in the compiler, making sure it executes correctly in the engines, and performing some basic optimisations such as replacing and inlining expressions.

When adding features to the compiler, there are two main places where you have to add code: the compiler itself, including the parser, the expression builder and exporter, and the engines (Roxie, Thor and HThor), including the common graph node representation.

As I was preparing the Keynote that I delivered at World-Comp'12, about Machine Learning on the HPCC Systems platform, it occurred to me that it was important to remark that when dealing with big data and machine learning, most of the time and effort is usually spent on the data ETL (Extraction, Transformation and Loading) and feature extraction process, and not on the specific learning algorithm applied.
