I listened to a very impactful podcast on Wednesday while walking my best buddy beast (happy birthday, Sunny). On the podcast, the speaker asked the audience five questions. One of those questions was, “When was the last time you changed your mind?” This question struck me. When was the last time I changed my mind? What motivated me to make that change? Would I be able to help others make a similar change should they ask for assistance? My mind raced through a series of events where I felt my mind had changed on something. Some were significant, others were trivial. But, the one thing I realized is that I change my mind often. It goes back to something I’ve mentioned in this newsletter a few times, resisting change is a DevOps anti-pattern. It also harkens back to the strong opinions, loosely held mantra that I have tried to adapt to. The speaker goes on to mention that being able to change your mind requires you to be humble, confident, and able to listen. Listen as in actually listening not pausing until the other person is done speaking.

So much of technology and working with it and in it involves change. Yet, as technologist and humans, we are terrible at change. We fear the unknown. We resist breaking the status quo. The fact of the matter is that as humans, our adaptability is what keeps us alive. Could the human race survive as long as it has without adapting to new things? No. So please, do not mock the person that tries new ways to do things. Do not chastise someone for getting smart home equipment to turn on lights. Those people are the ones iterating on things in their lives as part of their continuous improvement process. If your goal is to be the best light switch operator in the world then focus on that. Don’t worry about the rest of the world eliminating the need for the light switch altogether. The best people for business are the ones automating themselves out of their job. Keep giving them more stuff to automate. The podcast? The Lawfare Podcast: Chuck Rosenberg on Value-Based Leadership. Say what you want about Chuck Rosenberg’s politics, fine. But, you cannot question the leadership style and lessons learned from this podcast.

SpaceX hits two milestones in plan for low-latency satellite broadband: Since my days in the Air Force, I have always been interested in the satcom space (I did have to work with satellites often). If SpaceX has figured out a low-cost way to eliminate the half a second latency across satellite links I’d be very happy.

The CNCF takes steps toward serverless computing: The Cloud Native Computing Foundation has launched a serverless working group. To me, this is a natural evolution for serverless and the CNCF. However, in my opinion, DIY serverless/functions is a solved problem: use OpenFaaS.

Cloud Native and Serverless Landscape: Yep… Another CNCF landscape for your dart practice this time around serverless.

Grappling with DevOps Security: If you’re grappling with security at the speed of DevOps in your organization you should probably reach out to me for professional help.

Responding to new open source vulnerability disclosures: “A new vulnerability disclosure is not a new vulnerability. The security flaw existed in your library’s code all along, introducing a weakness in your application. However, when a vulnerability is made public, its likelihood of being exploited skyrockets.”
