Most of the things I learn on Linux, I’ve learned to play around with as virtual machines on my Windows Desktop. I’m putting this here for me to remember my steps in the future, but in case anyone else finds this helpful, yay, internet!
First of all, I’m a fan of VMware Workstation Player. Their website says: “The free version is available for non-commercial, personal and home use.” When you do pay for it (once you start making money or are working somewhere that you need it), it’s only $149.99 (as of 8/22/2019 when I checked)

DevOps practitioners must get feedback from quality assurance and security testing as early in the development pipeline as possible. When continuously building and deploying web application projects, being able to run a test and get output on it within minutes is a super power skill that gets teams ahead of potential problems. In this workshop, be prepared to use Docker to run multiple tests on your websites, learn about what the different tests are used for, and then become familiar with the output to interpret them for actionable feedback. We will analyze the following testing capabilities.

Organizations that have built a positive DevOps culture have transformed as part of a continuous and ongoing journey. The members of the organization should have a noticeable difference in how they behave presently versus how they behaved in the past. If the ultimate goal is to change the way the entire organization functions and operates, that means two things: changing the way everyone in the organization thinks about how they work and changing the way people behave.

I have had the opportunity to present this topic any many conferences this year and feel it is a critical topic for teams trying to make progress in their DevOps journey. Please feel free to continue the discussion with me on twitter @tomcudd.

This talk continues to be one of my favorites to give and I just keep getting the chance to present it. I will continue to submit it because it’s just a fun one. The Slides have been uploaded to SlideShare and my notes are mostly included here.

Thanks for everyone attending the Nebraska.Code() Conference. After the jump, check out a previous version of my slides and some notes on the topic I collected. I’ll likely be updating the slides a bit more soon, and will post when that happens on twitter.

For those hearing my talk on the topic or wanting a single place to get to each item in the Anti-Pattern list, here is a link to the original summary post and the individual posts for each anti-pattern I discussed:
Automation is the force multiplier that makes a DevOps effort so powerful. While it requires the technical skill and know-how to create frameworks for automating processes in an organization, an automation-first mindset is not easy to start out with. The rest of the DevOps anti-patterns are all about different modes of thinking and this one is no different.

All of the previous cultural pitfalls I discussed have been focused on systemic issues with organizations, teams, or groups of people. This is truly the one that requires individual effort to defeat. Even I have to be intentional about sharing what I know that would make others on my team have the same successes. This differs from the Tribal Knowledge Anti-pattern in that organizations create and force single threaded resources. This forces people to “stay in their lane” which creates hard boundaries in what people know how to work on. Information hoarding usually comes from an individual place of fear and insecurity.

In 2017, I took a very hard look at the issue we caused for Quality Assurance teams I worked with. By automating many Operations tasks, we did not speed up the whole development effort of the projects we worked on. The flow of work through an entire system is the only metric that matters to project leaders and clients, not that one particular piece is better. We had unintentionally created a new, bigger bottleneck by not supporting our QA team properly with what they needed to succeed.
