Bluetooth Speaker and Microphone on Raspberry Pi

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 […]

Kubernetes OnPrem Storage

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 […]

Ubuntu 18.04 Jump server setup

In my environment I have limited IP addresses, so we’re creating a new network and then allowing one server, the jump server, to sit between these network.  To do this, my jump server, aka: jump104 is “dual-homed”.  This means it has two network adapters:  One on the public network, and one on the internal private […]

It’s just lube

When looking to optimize your application deployment cycle organizations often turn to buzzwords such as: CI/CD (Continuous Integration/Continuous Delivery), DevOps and invariably the different products/projects they’ve heard of that do this.  In this buzzword blitz its a bit easy to get confused as to what does what.  Today we are hearing: Jenkins, Kubernetes, Mesos, Ansible, […]

Boot2Docker with Cisco AnyConnect

IP Masquerading (NAT in Red Hat)

In my lab I have a server that is dual homed.  It is connected to the outside network on one interface (br0) and the internal network (br1) is connected to the rest of my VM cluster. I want the VMs to be able to get outside.  So the way I did that (on RedHat) was […]
