Well that explains the low cost

A co-worker recommended Vizio as a top notch TV a while back and the price was ridiculously cheap when I shopped around to price one out. It was only for an occasionally used room and I figured even if it went bad after a couple of years it was worth the cost. Now I understand why the price tag is so low despite appearing to be a quality TV and I’ve turned as much of the default settings as I could find off since it’s used with an external device.

Shell Script for Apt-Get Security Based Updates

I’ve been slowly working this script into a cheap method of notifying me of updates available for Linux instances (Ubuntu specific) instead of purchased product or managed solution. It’s not fancy, flashy, API driven, cloud hosted, OAuth authenticating, or any other buzzwords. It does work though…
