#TS metaprogramming has a small enthusiast community but I don't know of any documentation

1. What keyword and structure is used as an implicit type parameter in order to implement type-level higher-order functions within the Typescript type system?

2. What 3 famous chord progressions are employed throughout the song Coil from Old School RuneScape?

3. How many 4-beat weave patterns are possible to perform with regular poi and a single one in each hand?

Thinking about this metric of like...

Come up with a set of three general-knowledge questions (by general knowledge I mean not stuff about your personal life; roughly the type of information you might find in a Wikipedia article) that you think uniquely narrow you down, in the sense that you feel confident you are the only person on earth who could answer all three questions correctly.

I can think of a few question sets like this for me, where I'm like 80% confident that I'm the only person who knows the answer to all three of them. If you have a little bit of obscure knowledge on a couple of topics, this is fairly easy to do I think.

Well, then the question is, how many meaningfully distinct sets of three questions like this do you have. Call that number your Obscurity Rank.

It's pretty cool to be of high Obscurity Rank, and one should strive for it.
