Docker operations slowing down on AWS
I’m CC’d on mails when things get slow, but never when things work as expected or are fast…oh well. Like an umpire in baseball, if we are doing our jobs, we are invisible. Subjec…

Golang SSH Security
Working on a project for a client recently, I needed to speak the SSH protocol in Golang code. So I started with the x/crypto/ssh package, part of the suite of libraries from the Golang developers which is not part of the standard library and not part of their usual compatibility guarantees, but more along the lines…

Building a NAS
I’ve been fascinated by high-volume, fault-tolerant data storage systems for a long time. I started my data storage setup in earnest with a 4-disk RAID 5 array on an ARC-1210 controller installed in my daily-driver Windows desktop. When that array inevitably filled up, I added another array on a second ARC-1210. That…

ZFS Is the Best Filesystem For Now
ZFS should have been great, but I kind of hate it: ZFS seems to be trapped in the past, before it was sidelined it as the cool storage project of choice; it's inflexible; it lacks modern flash integration; and it's not directly supported by most operating systems. But I put all my valuable data on ZFS because it…

Things I Wish I'd Known Before Using Vagrant
One of the ironies of working a lot with Docker, Kubernetes, and OpenShift is that I’ve had to learn a lot about Vagrant and Virtualbox. Mostly I use it to spin up OpenShift clusters on my local machine, but I’ve had to poke into lots of corners to get various other things working too.

Ansible open-sources Ansible Tower with AWX
Ever since Red Hat acquired Ansible, I and many others have anticipated whether or when Ansible Tower would be open sourced. Ansible Tower is one of the nicest automation tools I've used... but since I haven't been on a project with the budget to support the Tower licensing fees, I have only used it for testing…
