Spectral Attenuation Monitor

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…

Running Calculations on Separate Threads

In order to prevent my programs from freezing up while running long calculations, I generally run the calculations on separate threads.  In Java, this process can be accomplished by separating the GUI from processing.  In the code below, a thread for an instance of MyProcessing would be invoked using start(): e.g. “(new MyProcessing()).start();” would run indefinitely until T is made null.  T can be made null by calling stop() or by directly making T null.  Often when the GUI is closing, I…

Objectification of Incidents

Probably like most people, I tend to recognize data as a stream of values. Notice that I use the term values rather than numbers although in practice I guess that values are usually numerical. A data-logger gathering one type of data would result in data all of a particular type. Perhaps the concept of “big data” surrounds this preconception of data of type except that there are much larger amounts. Consider an element of value in symbolic terms, which I present below: there is an index such…

Common Coding Situations in Java

 This blog contains some snippets of code that I tend to use in Java.  I acknowledge that somebody else writing this blog might include different code.  Except for a short course at Sun Educational Services, most of my Java programming skills are self-taught.  I’m unsure if people with formal backgrounds in computer science might have different styles and conventions.  Mine have been shaped primarily by my needs.

Overcoming Aspects of Social Disablement in Data

When the performance of an employee is evaluated, ideally there are no externalities to complicate the analysis. If the employee has a computer that is constantly freezing up - or the servers in the company frequently operate slowly - the employee's performance data will reflect the functionality and effectiveness of these systems. If the company occupies a highly competitive market, declining sales data is attributable at least in part to competition rather than the behaviours of employees.…

Structural Relationships in Data

The first computer program that I encountered mimicking or emulating human interaction through language was called "Eliza." The version that I knew ran on the Commodore PET. It communicated in English. Eliza made comments that made some sense but which indicated lack of understanding of the conversation. If a person mentions "mother," Eliza might…

Development as Art - Hopscotch and Robots

When I read a blog, I often find myself in deep thought as I approach the end, trying to determine if the author has said anything that I might be able to use. A blog doesn't have to say anything. Nor does it have to be useful to me specifically. It might simply offer a personal reflection on life. As a person who also writes blogs, I…

Qualitative Engine for Organizational Simulations

Given the nature of the community, presumably many visitors already have a strong understanding of the nature of quantitative data. Perhaps more mysterious is the idea of qualitative data especially since it can sometimes be expressed in quantitative terms. For instance, "stress" as an internal response to an externality differs from person to person; yet it would be possible to canvas a large number of people and express stress levels as an aggregate based on a perceptual gradient: minimal,…

Data Instrumentalism

Being the son of a mechanic, I have spent many years handling power tools. I'm especially fond of a couple of hammer-drills in my possession. They can effortlessly drill holes through concrete. At least, this is what my father once claimed. He handed down his most treasured tools to me. I'm big on pliers and screwdrivers. This might be due to my vocational training as a technician. Even today - long after I completed my diploma and continued to further my education - I still carry a licence…

Universal Data Model - A Really Different Look at Data

The idea of environmental determinism once made a lot of sense. Hostile climates and habitats prevented the expansion of human populations. The conceptual opposite of determinism is called possibilism. These days, human populations can found living in many inhospitable habitats. This isn't because humans have physically evolved. But rather, we normally occupy built-environments. We exist through our technologies and advanced forms of social interaction: a person might not be able to build a…

The Awkward Road

This blog is about the peculiar nature in which software sometimes gets developed. I hope that many readers will recognize the relevance of data science in the examples taken from my own projects. I propose that development is the product of creativity more than accreditation. Creativity is something complicated that interacts with a person over his or her life circumstances. Many people know how to write . . . sentences and paragraphs. However, the ability to write well does not necessarily…

Java Coding Samples for Online Data-mining

In this post, I discuss the basic characteristics of code that I have personally used to extract online data - in a process these days often called data-mining.  I intend to cover some general features.  Those that wish to do so can also compile the coding samples.

Over the years, I have programmed in a number of computer programming languages including Visual Basic, Perl, Python, and LISP (AutoLISP).  The coding samples on this blog are written in Java, my language of…
