What seemed to be an untractable problem involving trillions of quadrillions of computations - far more than required to process all the data produced or collected on Earth since the beginning of times - has been reduced to something computationally feasible and even possibly quite simple. One applicant…Continue
I have an interest in optimization models as well as analytics. My son, who writes apps for the trucking industry, sent me a link to an article on how human factors may impact the "best" solution as opposed to the "optimal" solution to a class of problems.
So too our analysis may lead us in a certain direction but bring us to the wrong conclusion because important factors were not…Continue

I was offered a surface for father's day this year. I had an old iPad that I've used for several years, and I was curious to know if you can use the Surface just like a Windows laptop. While it has great features, faster Internet, and much more, the answer is clearly no.…
This is another example where, if you lack analytic skills, you will jump to the wrong conclusions. This news article was published in MyNorthWest. It's about the new law that went into effect a year ago in WA, allowing grocery stores to sell hard liquor. Here we provide 16 reasons that…Continue

Big data and data science is not just for good guys. If properly leveraged, it also provides competitive advantages for criminals, over their competitors, or to avoid detection.…Continue
Good day folks,
I'm conducting a data analytics project for a small supermarket and the IT guy sent me a file (.db0 extension) of their transaction details, but I'm unable to read it. Apparently it comes from the IBM 4690 Supermarket Application controller. I've done internet searches and nothing helpful comes up. The guy that sent it to me said he has never had to convert or read it into CSV or any other file format, so he can't provide any assistance. Can anyone help?…Continue

Recent revelations regarding the National Security Agency's (NSA) extensive data interception and monitoring practices (aka PRISM) have brought a branch of "Big Data's" research into the broader public light. The basic premise of such work is that computer algorithms can study…Continue

Debugging Hadoop jobs can be a huge pain. The cycle time is slow, and error messages are often uninformative --- especially if you're using Hadoop streaming, or working on EMR.
I once found myself trying to debug a job that took a full six hours to fail. It took more than a week -- a whole week! -- to find and fix the problem. Of course, I was doing other things at the same time, but the need to constantly check up on the status of the job was a huge drain on my energy and…

I am not an expert in database design, since most of my career I have worked with alternate data storage / data access solutions. But one of the very first projects I had to do back in 1985 when I was a student was to write the code for a fully functional database architecture, in Pascal, from scratch. You will probably find some of my questions naive, and some intriguing.…Continue
