A fictitious retailer which I am calling Malwart sells automobiles and automotive parts.  On this blog I will be focused on the sale of a particular automobile model called the Blair - a sporty compact that can be ordered in custom colour schemes.  Because all sales must be done by clients that also have accounts,…

The images on this blog are from an algorithmic environment that I first developed about 15 years ago - rendered using a graphical system that I wrote in Java.  A “differential lattice” is a structured array of differences between two points:  e.g. the difference between the closing price of a stock on day T-0 (today) and T-6 (a week ago).  Consequently, if the closing prices are $10.10, $10.20, $10.30, $10.40, and $10.50 (today), then 0/3 is from T-0/T-3 or $10.50 less $10.20 = $0.30.  A…

About a month ago in a blog, I introduced what I described as a “spectral attenuation monitor.”  At the time I only had an image from MS Works that…

It’s possible I haven’t shared my story of being asked whether people can leap over lampposts.  The question was posed by a university professor although I don’t recall the exact context.  In response, I asked if the people are on this planet.  He hissed at me, “Of course they are on this planet!”  Some planets have low gravitational fields that make it possible for humans to leap great heights.  At the time it didn’t seem like an oratorical question; and so I made an effort to answer it. …

I have been writing about the Crosswave Differential Algorithm for a number of years. I described in previous blogs how the algorithm emerged almost by accident while I was attempting to write an application intended to support quality control. In this blog I will be discussing the event model that powers the algorithm. Events are the details and circumstances…

In this blog, I will be considering theory developments from changes in methodology. But first I want to express an opinion on the significance of using numbers. A "number" represents an amplitude or magnitude: 5 pencils; 13 paperclips; 50 sheets of paper. The purpose of these numbers is to facilitate the counting of things that are presumably the same in a specific way: e.g. all 5 pencils are in fact pencils - for if 1 were an eraser, there would be 4 pencils and 1 eraser. The use of…

I have been using the term "mass data assignment" in my blogs. I thought I should offer the community some simulated examples. These are simple simulations: all the data is in one place in an agreeable format. The file contents are meant to be easy to peruse. When I was younger, there was a television series called "Stargate SG-1." I have a number of seasons on DVD. In this series, a special branch of the U.S. Air Force visits offworld sites using stable wormholes: teams enter the wormholes…
