Why Learn-by-Doing Matters
I founded Linux Academy over seven years ago to help people learn by doing. The idea was and continues to be that learning by doing helps us learn faster and retain more information. With the pace of change in our multi-cloud world, learning quickly with a higher retention rate has become more important in our everyday lives. Over the years, we at Linux Academy have taken on the responsibility to empower our students with the ability to learn by doing very seriously. It’s in our DNA.
But while Linux Academy is just seven years old, learning by doing is a bit older. John Dewey coined the term Learn by Doing and its philosophy in the early 20th century. His initial applications of experiential learning were in childhood development, but he wrote some pretty inspirational things that have much broader implications for multicloud training for Linux Academy.

Process ID Limiting for Stability Improvements in Kubernetes 1.14
Have you ever seen someone take more than their fair share of the cookies? The one person who reaches in and grabs a half dozen fresh baked chocolate chip chunk morsels and skitters off like Cookie Monster exclaiming “Om nom nom nom.”
In some rare workloads, a similar occurrence was taking place inside Kubernetes clusters. With each Pod and Node, there comes a finite number of possible process IDs (PIDs) for all applications to share. While it is rare for any one process or pod to reach in and grab all the PIDs, some users were experiencing resource starvation due to this type of behavior. So in Kubernetes 1.14, we introduced an enhancement to mitigate the risk of a single pod monopolizing all of the PIDs available.

SUSECON 2019 – What a great experience!
For those of you who made it to SUSECON 2019 in Nashville, I hope you had as great a time as I did. If you were not able to make it please consider coming next year. Without a doubt, this was one of the best events I have ever attended. And I am not just saying that because I work for SUSE.
