That note should be named "Thinking" to be honest. The goal is to collect a bunch of bullet points that I can read at any given time to remind me how to think better or common gotchas.
They are called multiple ways. I like to call mine a Personal Handbook[1] but I've also seen this being referred as Digital Garden or Personal Knowledge Base.
On the go I'll add a task to taskwarrior and get reminded when I sync it from the PC.

These rules are also on Google's Machine Learning Guide[1]. I find the website easy to parse. Definitely an awesome resource to review before jumping into any ML project!
I have a similar setup. Markdown files published in the open¹ using Hugo. That said, I'd love to have an easy way to add tagging and searching without having to create my Hugo template.
