Some favorite engineering terms and graphs

Three graphs I find extraordinarily useful because they are very dense and teach many useful terms in a very clear way all at once.

Data Science Map.

A wip towards organizing and mapping out the toolset needed for my career and various projects. The focus this year has been filling in gaps around dataviz and significantly augmenting my data modeling skills. Some work left there around network and dynamic systems. Decision modeling is a new concept to me and needs maturity.

Network Maps Analysis

I was interested in a genealogy of music genres using Wikipedia as a reference. I had some success, no doubt more to learn.

My first look at the data on wikipedia website was with wptools. wptools allows you to download wikipedia html and scrape data from them, for example content from info boxes.

I could have parsed that data into a linked list and then used that linked list to create a network map using GraphViz but before I had a chance to write that code I discovered dbpedia.


  1. The only real power is force (including coercion)
  2. The only good power is respect
  3. All other power is by agreement or convention

Law Spectrum

Thoughts on different ways societies deal with crime. Their general disposition. Needs some work, especially at the ends. Particularly since I am not sure what the x-axis indicates.

A Part of the Music

First there was the sound of the instrument, and it was thought that is all there was to music.

Then songs were composed and the song became a part of music.

Then songs became segments of larger works and these compositions became a part of music.

Then the musicians (and conductors) gave music their own interpretation and the performances they made became a part of music.

Then the studio was invented and now the treatment of the instrument and how music was produced and recorded became a part of music.


Strategies For Thinking

Compiling a list of methods for problem solving and of thinking of all types.

Life On Other Planets

I watched a documentary on the prospects of life on other planets. There was a lot of discussion about what are the necessary conditions for life. At first I was skeptical but after some thought I think I largely agree.

I took some notes during the video:

Stable System

  • Stable star (i.e. no large bursts/castoffs)
  • Stable and somewhat slow orbit
  • Post bombardment

Comfortable Environment

Balancing Needs with Copyright Duration

Because this is the year of the copyright and also because I have been fascinated in freedom of information I wanted to take a look at current US policy and visit, just a little, the debate between the desire for openness and freedom to appropriate and the desire to protect and monetize things which people/corporations developed and in many cases put forth considerable effort in time or money to develop.

Short of developing a theory, to which I have little to add, I sketched up what I think is a very succinct summary of the issue:

A New Web Data Management Strategy

It occurred to me that if I have a tool to manage tracking and another for invasive ads, then why can't I have even more tools to augment what I already have to provide a safer, more productive experience. I tried to establish what tools are necessary and whether or not they currently exist. I did my best to arrange them in a hierarchy.
