I used to work with a guy that had what looked a bit like a Schrader valve (I never got close and looked) a little bit behind one of his ears. I worked with him for a while but never asked what it was for. Any chance you could give some idea as to what it was for? I assumed he may have had a TBI at some point (I feel like I remember an IED story from him) and it was to relieve pressure or something.
I hated yaml with every fiber of my being when first had to use it, but I really wanted to use HomeAssistant and see what I could do with it. I hated it a bit less when I started using docker compose. I started loving it when I started using it as a way to explain json to non-programming IT types, trying to explain it without braces and brackets seems to get across easier. I guess its more human readable, but as a result formatting has to be spot on (those indents and spaces replace the need for brackets and braces).
One useful trick if you truly hate it but need it, write it in json, then just use a converter to change that into yaml.
