Understanding the Now - The Role of Data in Adaptive Organizations

Slow and Unaware

It was 2005. The war in Iraq was raging. Many of us in the national security R&D community were developing responses to the deadliest threat facing U.S. soldiers: the improvised explosive device (IED). From the perspective of the U.S. military, the unthinkable was happening each and every day. The world’s most technologically advanced military was being dealt significant blows by insurgents making crude weapons from limited resources. How was this even…

Framing Ambiguity, Incentives, and Actions

In the mid 90s, while working in government, I was given an invaluable bit of advice from an Air Force colonel who would become a trusted advisor and a dear friend. He said:

Perspective is elusive... I've worked with countless Ph.D.'s that would obsess over details which did not matter in the grand scheme of things. You seem to have the ability to operate on multiple levels. Don't lose the ability to see the bigger picture.

At the time, I understood…

Top Mistakes Developers Make When Using Python for Big Data Analytics

Interesting article by Karolina Alexiou.

Regarding mistake #1, I disagree. I do it all the time, and it's faster than finding, understanding, and fine-tuning a piece of code that will work for you, unless you are looking for something basic such as computing correlations for weighted observations. If you are good, your reinvented wheel will be better, implemented faster, more robust, and more customized than existing ones.…

Social Construction of Technical Trading Data

I heard an accountant once say that people in his profession are generally bad investors. I am uncertain if this is true. I never really bothered to confirm his assertion. He said that his reasons for believing so relate to the nature in which accountants interpret data, which he implied was rather literal. I personally almost always ignore "book value" - that is to say, the cost of acquisition. For me, the book value is similar to a figure of speech: the investment value never has to be…

In this article a new insight is added to the decision tool box. This insight is represented by an acausal rare, coincidental event that can have a huge impact on the decision maker's enterprise, although absolutely free. Such an event is called a…

Who killed the Storyteller in Marketing

I have just a little over three hours left to live. That’s the half-life of content these days, I am told.

A few hours ago, I was another small idea, floating in your head. Then you checked Buzzsumo to find what is the trending content of the hour. What will go with today’s coffee.

Voila, you had it. The themes and news that will drive traffic, maybe even stop traffic, for a few hours!

You started working. A few quick keyboard strokes later, you posted me, on all the…
