The Big Data Yawn
Over the past couple of months we have met with a number of oil and gas executives to demonstrate our Oil and Gas Solution built on Data-Tactics’ Big Data Engine (BDE). During these conversations it has become obvious that the very mention of "Big Data" produces an involuntary physiological response among business leaders - eye rolls and yawns. It appears that big data has reached the Gartner "trough of disillusionment". These executives have heard from a bewildering…Continue

In-memory database technology is fashionable in recent years as the price of RAM drops substantially and gigabyte chips become affordable. By taking advantage of the cost-performance value of RAM, leading edge database developers are boosting the performance of next-generation databases with in-memory technology. However, many developers who intend to adopt in-memory technology only think of speed in terms of RAM, and do not exploit the true power of in-memory technology.
This is an area of data science that the public is less familiar with. This example involves small data, simulations, and 18 years old crowdsourcing.
It's an attempt to explain the cause of the TWA Flight 800 that exploded near New York on July 17, 1996. I raised the possibility that a potential cause for the Malaysia Airlines flight that went missing last week, was being hit by a missile (accidental or not). Likewise, many people still believe that TWA 800 was destroyed by a…Continue

I have always had a great interest in how businesses organize in order to get things done. Here I raise some discussion points intended to stimulate debate.
Principle of Systemic Domains
Not that long ago, I was completing a graduate degree in “critical” disability studies. The critical part deserves to be in quotations since it is probably subject to interpretation and all sorts of misinterpretation. I am going to suggest that in critical…Continue

How do you know if an outlier is the result of a data glitch, or a real data point -- indeed maybe not an outlier. Difficult question to answer, but the chart below shows that in some cases, the outlier is not an error.
In this example, you could argue that we are not…Continue

I just came across this blog and thought it was an interesting point. i disagree. but its worth a discussion :)
While companies complain about lack of analytic talent, professionals complain about lack of jobs. Everyone wants to work for Facebook, LinkedIn, Google, Intel, Apple, Twitter or some hot start-up. It creates fierce competition getting a job interview, let alone a job. But companies that do not belong to this circle see very few candidates applying for their data scientist open positions; in addition, they are only hiring what I call technical developers (defined by a narrow set of technical…Continue

We are all increasingly active in the digital space. 70%+ of people in the EU, and growing, use the Internet*, all contributing towards more data generation. But public misperceptions and perspectives on data and how it’s used for marketing, threaten to limit data’s potential curtailing marketers’ abilities to provide personalised services. Careful data usage greatly enhances our lives. Unfortunately, fear or irresponsible use (a thankfully rare occurrence), along with some sensationalist…Continue
