Oh the weather outside is frightful, But the DevOps is so delightful, And since we’ve no place to go, Let It Snow! Let It Snow! Let It Snow! This song has been in my head all day as the US east coast has been coated in a blanket of frozen participation. We have not taken down our interior Christmas decorations yet either so that might be part of it too. Department of Choice Concepts Vladimir Vivien wrote a book on Go. Learning Go Programming was written over the course of a year and a half and is an attempt to make it easier for newcomers. I bought it and intend to read it. Department of Dafuq When I mentioned the leap second last week I was hoping it would go off without a hitch. That was not the case when Cloudflare had a globally impacting issue with its RRDNS software. Developers have a hard job, I believe all of us in DevOps recognize that. But, this is a good example of how an assumption caused a big problem. ...

2016 has come to an end. For auld lang syne, my dear! 2016 has gotten a pretty bad rap (deservedly so, in my opinion). Let’s try to leave the past where it is, dump the negative energy, and wake up to new opportunities. I like this time of year for the wrap-up pieces and year in reviews. Here are a few that I enjoyed this week: Predictions for DevOps in 2017 5 DevOps predictions for 2017 In 2017, I’m going to stop watching the news What I Learned in 2016 Department of Next Year’s Old Tech Please, for the love of God, do not let leap seconds bite you in the ass ever again. Percona has a great piece for getting this problem solved: Don’t Let a Leap Second Leap on Your Database! Department of Choice Concepts Julia Evans wrote a fantastic article (and comic), How to ask good questions. Essentially good questions come from the need to plug information gaps, not from a complete lack of knowledge. Do your research then confirm what you need confirmed. This is a skill more people need to solidify. ...

Merry Christmas and Happy DevOps! 🎅 🎄 🤶 Quick hitter this week as the family watches Elf. Department of Refreshment and Refurbishment Python 3.6 was released! The full changelog is available for your review. Ruby 2.4.0 was released! The full changelog is also available. GitLab 8.15 was released! I am not a huge fan of GitLab’s UI but the Auto Deploy feature looks intriguing. OpenJDK on Windows? Yep! Thanks, Redhat. Dominick Krachtus released a nice script to quickly spin up an OpenVPN instance in AWS called autovpn Tony Narlock has made his upcoming book, The Tao of tmux, available to read for free. Department of Choice Concepts David Gilbertson shares some performance tips during his experience, “making the fastest site in the world” Julia Evans has written a fantastic piece on container networking that I would highly recommend taking a look at. Department of Next Year’s Old Tech ClusterHQ shut its doors. Their software is still open source. DevOps’ish One-Liner of the Week Should you be in a position and need to figure out what systems are holding a high number of connections to a system login and try this out: ...

It was the week before Christmas 🤶 🎅 and all through the DevOps world not a creature was stirring not even a mouse 🖱. Hardly… You might be in a change freeze but the open source world is a glow with many gifts under the tree this week. Department of Refreshment and Refurbishment Linus’ gift to the DevOps world came in the form of Kernel 4.9. This is a large release coming in at about 22.3 million lines according to Michael Larabel with, “a bit over two thirds drivers”. Kubernetes 1.5 is out! PetSet is now called StatefulSet (beta), Windows server containers are available, and a slew of other features are now available. Docker spun out containerd, its core container runtime, into a standalone product, “and will be donating it to a neutral foundation early next year”. This is big news especially when you consider Alibaba, AWS, Google, IBM and Microsoft are all onboard the containerd train. CoreOS Linux has rebranded itself to Container Linux. The CoreOS team can do what they want as far as branding but I honestly think this is going to create some confusion in the marketplace. Think about explaining to an overzealous CTO who wants to use containers that Container Linux might not be the best option. ...

Welcome to this week’s edition of DevOps’ish where we cover Dev, Ops, and all the ish in between. Department of Choice Concepts I love the idea of dumping XML and JSON for HTML 5. Despite having to block people trying to pick fights on Twitter, this idea has been pretty well received. I would love to see the frustrations of JSON cast aside for something less syntactically challenging and more human readable. Department of Happy Little Clouds Ryan Scott Brown might have beat Amazon to the punch but AWS has launched a region in Canada! 🇨🇦 🇨🇦 🇨🇦 The general consensus is if a company that is doing business in Canada they are likely going to be diving head first into this AWS region. Canadian privacy laws make sure a lot of Canadian PII does not leave the county. Speaking of Amazon and privacy… A developer interviewing at Amazon had a rather unusual experience taking a proctored test. He ended up terminating the interview early and then as the proctor was unable to clean things up on the dev’s machine the dev terminated the termination. “The normalization of privacy violation has never felt more real.” ...
