Big Data Cartoon - What is text analytics?

Analytics may be the next big thing in Big Data, but it is very hard to define what it really is. Firstly, this word shows as misspelled in the browser and in Word or OpenOffice. Secondly, it's too vague and nebulous. As always, when in doubt, we turn to our illustrator, and our RK can illuminate us with a simple to understand cartoon that even data scientists can get.

Big Data Cartoon - What's the latest and greatest in Hadoop?

What's the latest and greatest in Hadoop? Ask this question, and many people will say "Real-time" and point to Spark. Look at Berkeley's AMP labs two-day seminar going on right now, for example.

But what is Spark, really? What are those RDD's? They stand for Resilient Distributed Datasets, but is it any clearer? We asked our illustrator to clarify this, and hopefully we got it explained.

An excellent presentation by Rohit Jain about exciting new open source product Trafodion

Rohit Jain drove from Austin and presented Trafodion (Welsh for "Transaction"), pronounced "Travodion" - for those in the know. Rohit is an HP Database Distinguished and Chief Technologist. The breadth and depth of his knowledge is amazing.

In turn, the audience did not betray the expectations.  Houston is getting its Big Data people, by importing them, and people from Cloudera, Hortonworks and DataStax were all represented.

Pizza was sponsored by HP - thank you - and Rohit has already uploaded the slides to the Meetup. Here are the main slides, and the architecture

, with this note from Rohit: "There was interest in the Trafodion Distributed Transaction Management (DTM) architecture. However, it is a bit dated. Since this presentation, DTM has now been implemented as HBase co-processor code & THLOG has been integrated with the HBase HLOG."

My comment: I started Houston Hadoop Meetup in 2010, with the expectation of an imminent Big Data Boom in Houston. I am still expecting. This was the first meetup though where we had active Big Data professionals, but they were all imported, as I said, from Big Data companies. We are still yet to see native Houstonians and Houston companies doing Big Data. Again, it's coming, and our meetup is one of the focal points.

Big Data Cartoon: Big Data needs big muscle

Inspired possibly by this cartoon in New Yorker, our illustrator has set out to tell us that being in Big Data, you travel a lot, and of course avail yourself of the exercise facilities found in each and every hotel. My latest was a packed gym in downtown San Francisco.

Lately, I've been noticing that trainers at Elephant Scale have been gaining muscle weight.

Got an Ubuntu laptop!

Quite powerful and good-looking, from System76. (It is the one in the middle). Now I have a chance to be productive while traveling or working in friends' place.

I am planning to add Windows in a VM, stay tuned...
