This is a no-holds-barred, in-depth exploration of the way in which we can participate in the blockchain economy. The following is an excerpt from the book, Tokenomics by Thomas Power and Sean Au and published by Packt. One of the biggest challenges of playing in the ICO space is trying to understand the rules to play by. Regardless of what anyone says, we all live in a world bound by rules. We always have and always will, yet technology knows no ... Read More

The opportunity to watch and coach the University of San Francisco (USF) students during our annual Hackathon with our friends at Good Dataprobably taught me as much as it taught the students. The lessons learned I’ll share here will not only benefit future classes, but my customers.  It also gives me an opportunity to make special mention of one Hackathon team that really delivered the goods! This year’s Hackathon focused on analyzing air traffic delays (a subject area with which I unfortunately consider myself an expert).  We used data ... Read More

In 1963 Benoit Mandelbrot published an article called “The Variation of Certain Speculative Prices.”  It is a response to the forming theory that would become Modern Portfolio Theory.  Oversimplified, Mandelbrot’s argument could be summarized as “if this is your theory, then this cannot be your data, and this is your data.”  This issue has haunted models such as Black-Scholes, the CAPM, the APT and Fama-French.  None of them have survived validation tests.  Indeed, a good argument can be made that the test by Fama and MacBeth in 1973 should ...

With time we have seen more and more of mundane manual work being replaced by automation through advanced engineering, computers, robotics and now IoT. We believe that recent advances in AI (or Deep Learning to be more precise) will help accelerate this trend towards automation in a fascinating way. This is because AI adds one very critical component that the factories have been missing till today — “The ability of machines to see”. With computer vision enabled robots, a lot ... Read More

They were invented by Bob Frankston and Dan Bricklin, founders of VisiCalc, and I had a chance to chat with both gentlemen a couple of months ago. I highly recommend watching this TED talk with Dan Bricklin: It's important to understand for which purpose electronic spreadsheets were built in the first place if we want to anticipate what their future might look like. In response to my question in how far the future of spreadsheets is different from its ... Read More

A So-So Second Date with Julia A few months ago, I wrote a quite positive blog on the Julia analytics language, reveling in its MIT pedigree, its comprehensible structure, and its interoperability with data science stalwarts R and Python. I demonstrated some of Julia's capabilities with a skinny data set of daily stock index values, and I showed it collaborating with R's powerful ggplot graphics subsystem. This time around, I decided to test Julia against a much meatier data set -- one that I've already examined extensively with both R and Python. I find ... Read More

Summary:  We’re rapidly approaching the point where AI will be so pervasive that it’s inevitable that someone will be injured or killed.  If you thought this was covered by simple product defect warranties it’s not at all that clear.  Here’s what we need to start thinking about. So far the press reports of AI misbehavior fall mostly in the humorous or embarrassingly incompetent categories.  Alexa orders doll houses when a little girl asks it to.  Robot guards fall into pools or push people over.  Google tags black people as ...
