112: Kubernetes Any Way You Want It, Passing the CKA, GitOps, Joy Sparking Meetings, Processes, Containers, and VMs. Oh My! and More

I’m struggling to write an intro this week (probably broke a rib). But, I did write a tweet that got a lot more attention than I thought it would this week. I’d like to talk about it:

This is not to say I decline every meeting invite I get. It’s to say that if an invite is not complete (an agenda, location, time, etc.) I’m highly likely to decline it. Also, if there doesn’t appear to be value in my going versus something else I could be doing I will typically decline stating the reason politely. In general, I enjoy the meetings I get invited to because I love the work I’m doing. But, I did decline a meeting invite a little bit ago.

Triangle DevOps presents DevOps is Not War with Chris Short of Red Hat
Over the past 500 years, there have been 16 cases of a rising power threatening to displace a ruling power. 75% of those cases resulted in war. Although your organizational transformation probably won’t lead to war, it could be contentious. History can help prevent conflict when driving change. This talk will analyze human tendencies, historical data, and provide real-world examples of how to prevent conflict during your DevOps journey. SPONSORED

CEO of IBM Says Hiring Based on Skills Instead of College Degrees is Vital for the Future of Tech — I’m still grappling with this one personally. No, I didn’t go to college in the traditional sense. But, I also think colleges play an important role in our society. The real reason this is a topic here in the US is due to the enourmous cost of tuition. For example, we’re estimating Max’s (age 3) university tuition to be close to $200,000 USD. That’s the equivalent of ₹14,180,100.00 Indian Rupees, £151,521.00 Pounds, ¥1,349,460.00 Chinese Yuan, or €175,431.00 Euro.

DevOps’ish Tweet of the Week

I found out about this first thing Friday morning when I e-mailed Jess asking about Ansible taking advantage of GitHub Actions. Whatever the reason for this abrupt departure, I trust Jess’ ability to take care of Jess better than anyone else. No one should judge Jess for leaving GitHub regardless the reason.

Also, if you work on GitHub Actions, please reach out to myself or John “gundalow” Barker. We have thoughts.
