3 Stages of Technology Development

  1. Step 1: Establish goals, attach figures to critical requirements then brainstorm ideas. Sort fixable vs unfixable.
  2. Step 2: Establish detailed requirements and investigate remaining solutions. Get familiar with each technology/solution. Brainstorm implementations. Choose the best solution.
  3. Step 3: Dive deep, test, iterate and establish complete documentation.

Hierarchy of Integrity

I've been thinking a lot lately about health, safety and security. I think originally I was interested in studying ideas around the environment and the environment's impact on me and also my impact on the environment. My focus here was on capturing all the possible bad things that can happen and then how to mitigate, detect and prevent them. But unexpectedly I found that it also tied in with another hot topic for me lately: respect and integrity.

Finding the Pattern.

I love graphs, plots and charts. There is something almost magical about their ability to ask a question, analyze it and make a point all in one place.

I think that's why I love to visualize data. I love how powerful the perfect graph can be by allowing you to quickly and deeply grasp a concept (especially for large data sets) by telling a story and using the eye to draw your attention to the right places. Our minds are great at seeing trends and patterns in data when it is visualized.

Effect of Room Correction on Home Theater Performance.

Introduction
Is room correction worth it? Additional processing introduces new artifacts. But it also corrects others caused by room modes and reflections. I think a (somewhat) quantitative look at the numbers will help answer this question.

So what does room correction address?

  • Amplitude response over frequency (frequency response) caused by room modes and speaker/system defects
  • Transient response caused by room reflections or phase distortion in drive electronics and speakers

And what does it introduce?

Similarities.

I am almost all the way through Ken Burn's "Vietnam". I've watched every episode twice and I am blown away at how visceral, gritty and real it feels from my couch. And it has changed me.

Big Bang Reality Check.

I was reflecting on some recent ideas about the "human centric" understanding of our universe. Our minds and bodies are naturally designed to work within a certain size of objects, quantities, spaces and within human perception. And for everything outside that space we scale things to fit our understanding.

Calculus: tbd (Part 5 of x)

.

Calculus: Integrals (Part 4 of x)

Preface
This series is aimed at providing tools for an electrical engineer to analyze data and solve problems in design. The focus is on applying calculus to equations or physical systems.

Introduction
This article will cover integrals.

There are many calculus references, the one I like to use is Calculus by Larson, Edwards and Hostetler.

This also assumes you are familiar with Python or can stumble your way through it.

Calculus: Derivatives (Part 3 of x)

Preface
This series is aimed at providing tools for an electrical engineer to analyze data and solve problems in design. The focus is on applying calculus to equations or physical systems.

Introduction
This article will cover derivatives.

There are many calculus references, the one I like to use is Calculus by Larson, Edwards and Hostetler.

This also assumes you are familiar with Python or can stumble your way through it.

Calculus: Limits of Functions (Part 2 of x)

Preface
This series is aimed at providing tools for an electrical engineer to analyze data and solve problems in design. The focus is on applying calculus to equations or physical systems.

Introduction
This article will introduce limits.

There are many calculus references, the one I like to use is Calculus by Larson, Edwards and Hostetler.
