A great practical post on team organisation, bridging both development and operations work, as well as planned and ad-hoc tasks. Lots of good points and observations, if you’re organising or working on a team you should read this.
A Gartner piece entitled Seven Steps to Start Your DevOps Initiative. Lots of good observations in here, and the key challenges picked out are interesting if you’re talking with your CIO or similar level execs.
An interesting talk from the recent Devopsdays Chicago, entitled Rules of DevOops, all about making mistakes. Lots of observations about how teams work and communicate, and why abstractions can hurt team work.
A nice quick example of writing a test to confirm you’ve really fixed a bug, this test checks for a recent bash vulnerability using ServerSpec.
Lots of people are building microservice based systems at the moment so this post, with a number of techniques that worked and a few that didn’t, should be useful for anyone getting started.
A quick presentation with 4 strategies for avoiding scheduled maintenance. Good tips if you’re regularly taking evenings to deploy your services.

Taste tester is another workflow tool for Chef, it launches a Chef-Zero instance locally and then checks what changes would happen to a remote machine with your local changes.
