Anything to do with Kubernetes
Okay, someone out there understands how Kubernetes works, because it is actually out there in the wild. But come on, only a small priesthood of devoted gurus really know how to configure the cluster topology, networking, role-based access controls, custom resource definitions, ingress controllers, storage classes, pod disruption budgets, affinity rules, and the rest of that 47-ring circus.
Most of us know the very basics of YAML and piece together something that works and then pray that it doesn’t break. Admit it, 90% of your Kubernetes setup was copied and pasted from someone else’s working configuration that you only half understand.
Unicode and character encoding
Many of us grew up on good old ASCII and ANSI character sets. Then Unicode came along and opened up the digital universe to emojis, endless Wingdings, and non-Roman characters. Unicode is great—but it’s pretty much impossible to understand. For instance, it feels like Unicode characters should be two bytes in size… except when they aren’t. But that’s just me. I have no doubt that the rest of you can describe the differences between UTF-8, ISO-8859-1, and Windows-1252. Sure you can.
