The Full Stack: Apps, AI, DevOps, Infrastructure
If you ever want to get a real perspective on the destruction our species has done to the planet and most of the other species on this earth, this is a great read. I was fascinated by the accounts of our ancestors spreading from Africa to the rest of the world. I read in horror…
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…
I finished this book in about 1.5 weeks. I had some airplane travel time but I was riveted. I was appalled, saddened, and shocked at the same time. 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,…
Today we had to work on switching between two kubernetes clusters. The commands of the day are:
|
1 2 |
kubectl config get-contexts kubectl config use-context <context> |
It’s surprisingly not so simple. Perhaps there are tools out there that people know of to make it easier? What I’ve been doing is taking to ~/.kube/config files and concatenating them together. As an example, my config…
Big things of course! Took the whole family to Europe for 2.5 months. This was the greatest. Kids got such an education on this. So happy we got to do this. I worked with a lot of customers and internal Cisco people while over in Europe. It was nice to finally be on their timezone…
I haven’t worked on VMware for a while but needed to work on a project to automatically install ESXi on a few servers. I invented a tool called KUBAM that was originally for deploying Kubernetes on UCS Bare Metal (KUBAM) but have realized there are a lot of people that can benefit from the use…
My colleague Pete Johnson, at Cisco has released a blog about a project called FONK. I wanted to talk a little bit about why its important. iOS Developers Let’s first start back with the dawn of mobile application development. Pretend you are an iPhone developer back in 2008. You know Objective-C and you know how…
I’ve been working over the last year off and on on different smart contracts. What follows are some technical details I sent to some of my colleagues here at Cisco regarding gas price and gas limits. Two important parts of Ethereum that are not understood very well: Units and Gas. Units 1 Ether in Ethereum…
If you want your own Jarvis from Ironman the first step is to have a computer that can listen to what you say and then talk back to you. The software for that is the hard part but with some AI and RNNs we can get some pretty good functionality. That comes later, so let’s…
Lately I came across a few bare metal servers in our lab and decided I would test some of my ideas on setting up a bare metal kubernetes cluster on these nodes. I started thinking that if I were to do so I would need some persistent storage. There were a few options I could…
