Provisioner I’ve been working on Provisioner for a while now and it’s starting to come together. Most recently I rolled out complete API documentation as well as a brand spanking new website (powered by Jekyll and Github Pages). I’m still trying to think of more use cases, so that’s part of what I will be working on next, as well as better documentation at …
Viktor Petersson, Screenly I was recently interviewed by Dave Haynes of Sixteen:Nine about Screenly.
I recently had to migrate a number of VMs currently running on an NFS share to an iSCSI target. During my research, I was surprised how little documentation there was around this, so I decided to whip up this quick little piece about how to do it. Here are the steps: Create a new iSCSI target (one per VM/image you’re migrating). This step varies depending on …

(Behind the scenes, this dynamic inventory is using Apache Libcloud, which is a great Python library for interacting with …
The built-in Internet Sharing in OS X is very handy. When I’m on the road, I frequently use this to share my laptops WiFi connection with other devices over a wired connection (such as a Raspberry Pi, when I work on Screenly). If you’re connecting some kind of headless device, you will likely want to connect to this device over SSH or similar. The only …
I’m a huge fan of autojump. It allows me to quickly navigate my filesystem in ways without having to type out every folder. There is however one task that I frequently that I wanted to make more efficient: create a new folder and then jump into said folder. Normally, this would simply be: $ mkdir foo $ cd foo This feels somewhat inefficient, so I wrote a …

Not only do they lack things like Two-Factor Authenciation (2FA), but they also have this really frustrating login system. Well, today I had enough and whipped up a CLI tool that allows you to generate the …
