This article I followed was a little outdated. Things do change a lot in 3 years. It’s mostly the same as the function seems to work but the implementation does not. Following the hints here I was able to get this to work. The big one was you need to refresh your browser. I think…
While working at Cisco I developed a project called KUBAM: A simple bare metal provision tool for UCS. I updated the kubam.io page and am now offering support for $500 / node per year. I couldn’t do this at Cisco because I could never get it officially recognized by the powers that be. That is…

On Wednesday I attended the funeral of Brad Jackson, a beloved former Cisco colleague. His story is not one for me to tell, but suffice to say we will all greatly miss him. The story I can tell is the outpouring of love and support shared by the greater Cisco community and how much that…

The book is a true story about a company named Theranos founded by Stanford dropout Elizabeth Holmes that appears to have falsified and misled investors, partners,…
