Some time ago I had some kind of error or corruption with my *Google Play Games* on my *Nvidia Shield TV* console. I am also a *Google Suite (GSuite)* subscriber which adds additional constraints. 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. As it turns out there are a lot of hidden secrets that you need to check / setup before it all works. And any games you've played so far will probably lose their unsynced data.

**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.

**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.

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.

One of the biggest difficulties I have getting fit is the lack of metrics on progress. I have no way of knowing whether or not a workout is effective or whether or not I'm making good use of my time. Fitness trackers are available now although most of them only track footsteps which to me is useless (maybe I'm wrong).

In addition I also have a terrible time getting quality sleep. I wish there were a device that could monitor and debug my sleeping difficulties.
