I'm going to try to implement the Y combinator without looking! Why? Because I'm procrastinating. I have work to do, but don't want to, and its the weekend, but I can't do pure recreational because I compulsively need to do something that feels legitimized with the veneer of 'learning' in a skill tangentially related to 'my career', so here goes.

The Formula

This is basically cheating, but off the top of my head I recall that the formula for how the Y combinator looks goes something like this:

Y(f) = f(f . f)(f) yeah no I don't remember at all. It has the messy spaghetti quality of nested function calls that

    SELECT 0, 1, 1
  UNION ALL
    SELECT b, a+b, n+1 FROM fib
)
SELECT a FROM fib WHERE n<=8;

    return home; }

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2020-05-31: I won't be maintaining this page or responding to comments anymore (except for perhaps a few exceptional occasions). ]

---

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.
