ChefSpec Cheat Sheet
When it comes to testing your Chef cookbooks, currently there seem to be two tools that build the standard in the Chef community: ChefSpec and Test Kitchen (with Serverspec, which is the third tool). Where Serverspec can be used for an outside-in testing approach for your infrastructure, ChefSpec is more like unit testing or input testing for your Chef cookbooks. In this blogpost I’ll try to provide some best practices and snippets for common use cases.

Skill Radar and Technology Radar
As a (web) developer, keeping track of all innovation that happens around you can be a hard job. Figuring out which technologies to adopt and which to skip, documenting progress in adoption and communicating it with team mates and colleagues at work is something I was looking for a good solution for quite some time. Inspired by the Technology Radar from Thoughtworks I had a nice conversation with Heiko from Emendare during one of my coaching sessions with him and I wanted to share some insights and methods we came up with. We recently kickstarted a Technology Radar and a Skill Radar in our team - here is a short summary of how it works and what we did to create them.

Installing TYPO3 Neos in Docker
The goal of my “Getting Started” tutorial is to have a TYPO3 Neos installation running within Docker containers on Mac OS X. There are several tutorials and repositories available to achieve this (see Resources further down), I decided to use the Million 12 TYPO3 Neos Docker image. We will use the Neos Demo Site provided by the Neos Team as our example website. Since it is recommended to use this site package as a starting point for your own Neos projects, you not only have a “Dummy Site” at the end but a working Neos environment for your own projects.
