Beginners: Learn how to Program - with Python! 
Yup: I have kids. Yes - I routinely wage war trying to get each to learn how to enjoy WRITING games, rather than playing them.

While I too have been know to favor a keyboard-game or three, while teaching complete beginners how to program, over the decades I have discovered that the key to success is to never assume ANYone knows ANYthing. =)

In as much as I have a professional training experience designed to welcome complete novices into the wonderful world of Python Programming therefore, I decided to share the start-up lessons from the same on a new Pro Python play-list on YouTube.

DIY SQLite Videos ... and Inspiration? 
Inspiration.

Where does it come from?

No matter what we believe sparks our brain-joy, surely we all can understand how inspiring words from others can help "make our day"?



So as I set my hand to sharing a few videos designed to help others use SQLite, when it came time to select a set of non-trivial data for demonstrating SQL data-management techniques, I was inspired to use the data from our own Mighty Maxims Project.



Almost forgetting that I also have a Mighty Maxims Book (sales have been "that good" ;-) here is our video Playlist.



So if you would like to learn how to use SQL, as well as SQLite, enjoy our free videos... I'll be glad you did! (lol)

And if you "like" and / or purchase the book, I'll SURELY know who you are (i.e. "THANKS MOM" ;)


Enjoy the Journey,

-Rn

Hadoop 2.2.0 in the Hortonworks Sandbox (HDP 2) 
For the benefit of my fellow Hadoop-ies, as I work thru the evolving coolness of the Hadoop User Experience (HUE) under HDP 2 I wanted to pass in a few observations by-value.

Use Java 6


While we could use Java 1.7, note that the following message means that we had better not use the same as the default compatibility mode:


The google-candy here is:

Java MapReduce
MaxTemperature : Unsupported major.minor version 51.0


What the run time is trying to tell us is to use Java 1.6.

Logging into the VM will - of course - verify as much:



The solution is to simply re-deploy as a JDK 1.6 rendition. Even the Job Designer's "Job Design" need not change.

Moving the source code from the 3rd edition of O'Reilly's "Hadoop: The Definitive Guide" by Tom White to Hadoop 2.2.0, I am also bumping into allot of compatibility warnings and issues.

Stay tuned!!
