You'd think that, but I had an auditor that had guidance requesting confirmation of security cameras on the servers. They wanted to drive to the AWS data center to see the cameras. If the drives got stolen, you'd better make sure AWS shares that video with you.

This was my introduction to K3s as well. RPis running K3s with enough resources left over to actually do some small tasks. I hosted a small data pipeline that analyzed trading data from an MMO. It was as fun as it was impractical, and I learned quite a bit.

I can't tell you how many times I pipe in rev to put my text where I want it for cut (then rev it again).

Abbreviated example, getting the service names from a k8s cluster looks roughly like (actual command does a bit more processing):

kubectl get deployments -o wide | rev | cut -d'=' -f1 | rev

But if it's just gobbling whitespace, xargs without a command can be your friend.

$ echo "key: value" | cut -d: -f2 | xargs

value

My brain generally goes "rev sed head tail xargs cut tr ... screw it, I'll use python ... someday I shall learn awk." There's a young engineer on my team that knows awk, and I'm envious.

I've been out of grad school for a bit now, but 10 years ago is about right. There were a lot of things being published about compilers that might have well been direct ports of papers written in the 70s, "now for JITs." And honestly, if you read some of those papers from the 70s about automatic parallelization and such, it was pretty freakin' cool. And there were memory guarantees in Fortran that were not present in C that made it non-applicable. Java had most/all of those guarantees, which is what I think brought about their revival. That's probably not the whole explanation, as I'm not sure why it took Java so long (these were 2010+ papers, 15+ years after Java came out).

In this type of scenario, it's sometimes because there are two or more implementors that are trying to develop the standard in a way that makes their existing implementation compliant. Likely there were existing scripts that relied on the behavior being specific to that implementation, so it was explicitly made optional, which is viewed as better than not adding the behavior to the standard at all. "May" is just a polite standards way of saying "Warning: check yourself before you wreck yourself."
