Oh look! There’s a 666 in the epoch this week… Great! But, as one of my co-workers and I always say, we’re going to “will it” to be a good week in DevOps . It usually works out too.
Department of Choice Concepts
Nitin Agarwal breaks down the Docker filesystem (AUFS). It is a rather simplistic presentation. If you know someone struggling with the concepts it’s definitely worth a read.
Brendan Gregg built out a very simple page containing ALL his works on Linux Performance. I do not think you could bookmark this page enough.

Department of Data Defense
There is some pretty insane stuff happening in Russia. Some pretty senior cybersecurity folks are being held by a military tribunal. Keep an eye on this one.
Department of Refreshment and Refurbishment
DZone recently released their Guide to DevOps: Continuous Delivery and Automation. Lots of cool concepts and stories for you to ponder over.

Not DevOps But Still Cool
Gopher Academy is launching training courses. I will be attending the Introduction to Buffalo — Web Development in Go on January 31, 2017. Take a look at what is coming up.
DevOps’ish One-Liner of the Week

aws ec2 describe-instances --query "Reservations[].Instances[].{ID: InstanceId, Tag: Tags[].Key}" --output text | grep -v Name
