Plex Server Install
December 31, 2019
With the rise of multiple streaming services with varied content, there seems to be a push back to having your own personal collection of movies and shows. A person could go down the road of buying a small form factor motherboard, CPU, Hard Drives and install Linux, deal with local network issues to get the content available outside the house; not including upkeep on the physical as well as the software. Plex has a online server you can install and use to stream your own personal content online, ad free. A notice: THIS GUIDE DOES NOT CONDONE ILLEGAL USE!

This switch involved leaving Wix, a website hosting service to using GitHub pages.
Ubuntu 19 - Enable Hibernation
August 24, 2019
After spending the summer playing with differnet OS's, I found that Debian had hibernation ready capability. Unfortunately, I ran into some other issues with it and my laptop and decided to go back to Ubuntu. Ubuntu 19.04's install process does not create a large enough swap partition to allow the system to hibernate, which Debian did.
OWASP Cornucopia
August 7, 2019
Since the CyberCamps ended last week, I have had time to begin preparing for the Fall semester at Cabrillo College. In that time, I have also been gathering new resources and realigning the baycyber.net website for the academic year's vision and goals. In that time, I came across OWASP Cornucopia, a card game that piqued my interest. After getting the college to pay for the printing of the cards, I learned how to play.

This guide will show how to get Kali Linux running on a GCP image.
