2. "A Practitioner's Guide to Wide Events" by Jeremy Morrell.
"Adopting Wide Event-style instrumentation has been one of the highest-leverage changes I’ve made in my engineering career. The feedback loop on all my changes tightened and debugging systems became so much easier. [..] where do you even start? What data should I add? We’ll cover how to approach this in tooling [using an OpenTelemetry SDK] and code, an extensive list of attributes to add, and I’ll respond to some frequent objections that come up when discussing this approach."
3. "How we avoided an outage caused by running out of IPs in EKS" by Fabián Sellés, Adevinta.
"My team maintains the cluster and a myriad of services that support applications from observability to security passing through networking. One evening, we received a page that some DaemonSets were failing. After logging on to the server and checking the pods status, our worst fear was confirmed as we read the error:

5. "Kubernetes Resource Model, Controller Pattern and Operator SDK refresher" by Vibhav Bobade.
"I have been writing operators for a while, but along the way I have forgotten what SharedInformers, Informers etc. are. As a refresher I want to understand what these are and understand this more intuitively so that I never forget it. Anything that I might not have mentioned here is something that I already know or any beginner or intermediate Kubernetes engineer would. The notes given below are a mix of notes from Eddie Zaneski's "Understanding the Kubernetes Resource Model and Controller Pattern" talk and a bit of personal exploration on these topics."
6. "Install Kubernetes from Binaries".
"These are the notes I took while learning binary installation of K8s. I installed 1 Master and 2 Nodes. I didn’t use scripts or HA during installation. These notes are suitable for: cultivating a practical understanding of various K8s components; installing a minimalist environment."
