Rugged Watch Criteria

Watches are jewelry and as a result there is a wide variation both in price and quality. I'd love to perform a study and scatter map price and quality. The most you could hope for is a straight line: higher price results in higher quality. But in reality I think what you'd end up with is a cloud with very little statistical correlation. Even if you were able to normalize for precious metals or technologies that lend themselves to aesthetics rather than robustness I don't think if would make much of a difference.

Correcting A Broken Google Play Games Installation

Some time ago I had some kind of error or corruption will my Google Play Games on my Shield TV console. Any time I chose to log into google games the system would log in but then the game could not detect the log in. It was odd and I knew the issue was probably a local error. Here's how I fixed it:

First google requires a couple pre-requisites:

  1. A google account
  2. A google+ account

Steps to fix the error:

Linear Algebra in Engineering: Summary (Part 7 of 7)

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 linear algebra to systems of equations or large sets of matrix data.

Introduction
This article will attempt to organize the previous series of articles into a decision tree allowing you to quickly choose the best method for a particular problem.

Procedure
First, ask yourself some questions about your data and the type of answer you need.

Linear Algebra in Engineering: Trend Analysis with with Polynomial Least Squares (Part 2 of 7)

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 linear algebra to systems of equations or large sets of matrix data.

Introduction
This article will demonstrate the use of least squares fit real data to a polynomial.

Linear Algebra in Engineering: Equilibrium in Linear Systems (Part 1 of 7)

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 linear algebra to systems of equations or large sets of matrix data.

Introduction
This article will demonstrate the use of matrix algebra to solve for equilibrium in systems. This is common in network flow, economics and electrical circuits (current and voltage analysis). We will apply exact and least squares solutions.

New Smartphone is a Disappointment

I must express my disappointment in my new smartphone. I thought upgrading from the dated, failing and left behind Samsung Galaxy S III to the larger, faster, updated Samsung Galaxy S6 would be just the tool I needed to bump my game to the next level. But it was not so.

On the plus side the updated audio provided a much higher fidelity listening experience. And the display is gorgeous. And the ambient light sensor actually works (even in the dark it can be adjusted to a reasonable level). The camera is significantly faster, more capable and higher resolution.
