Repping for SysAdmins at the Space Coast! #NASASocial

Date October 30, 2014

Like most children, I was a huge fan of spaceships when I was little. I remember watching Space Shuttle launches on TV, and watching interviews with astronauts in school. I always wanted to go see a launch in person, but that was hard to do when you were a kid in West Virginia. As I […]

Appearance on @GeekWhisperers Podcast!

Date October 29, 2014

I was very happy to visit Austin, TX not long ago to speak at the Spiceworld Austin conference, held by Spiceworks. Conferences like that are a great place to meet awesome people you only talk to on the internet and to see old friends. Part of the reason I was so excited to go was […]

Date September 14, 2014

One of the annoying parts of making sure that you can successfully migrate virtual resources across a vSphere datacenter is ensuring that networks and datastores are not only available everywhere, but also named identically. I inherited a system that was pretty much manually administered, without scripts. I've built a small powershell script to make sure […]
