Python is an increasingly popular object-oriented, interpreted and interactive programming language used for heavy-duty data analysis. Python is designed for ease-of-use, speed, readability and tailored for data-intensive applications.…Continue
It’s time to forget the ‘vertical’ perception of Big Data, i.e. vast volumes and ROWSof data, and start to think about the ‘horizontal’ reality and true power of data. TheCOLUMNS of rich, informative data is where your real value lies and where truly smart decisions will be made.

The South by Southwest Interactive conference in Austin, Texas captivates our imaginations for a few days every year. How do they do it? The conference makes science and technology look both lucrative and cool. Bright-eyed startup teams leave the conference with dreams of being the next Twitter or Instagram.
We need to see more of this momentum, especially amongst Millennials. To generate interest in technology careers such as those created by the Big Data wave, incentive…Continue

2.7 zetabytes of data exist in the digital universe today according to recent IBM case studies. Yes, you heard right. I said zetabytes; 10^21 bytes or 1,000x larger than an exabyte (which itself is a billion times larger than a gigabyte). From a visual perspective, if the cup of coffee on your desk was equivalent to one gigabyte, a zetabyte would have the same volume as the Great Wall of China. Now multiply that number…Continue

The buzz is one of the most powerful forces in the market, and knowing how to master this important marketing channel is critical. Word of…
